Jiangsu Yuda Power Station Auxiliaries & Valve Manufacturing Co., Ltd. is a member unit of Chinese Society of Electrical Engineering, which is a special manufacture of bypass device of steam turbine and temperature reducing and pressure reducing devices. Leaded by Professor Wang Huiyu in many years, our company had a systematic development and research on temperature reducing and pressure reducing devices. We absorbed advanced experience of Germany ARCA Corporation, Sweden CCI Corporation, Sulzer Corporation, TW Company affiliated to Germany Siemens Corporation and so on; researched and developed new welding case type decompression valve (patent no. ZL02218384.1) matched for temperature reducing and pressure reducing devices, segment formed control valve (patent no.

Through continuous promotion and practice, our product will be accepted by more and more clients. We will make a brief introduction as following:
一、旁路系統(tǒng)的主要作用
I. Main functions of bypass system
1.1在鍋爐啟停過程中，運(yùn)行人員可以通過增加鍋爐負(fù)荷來提高升溫升壓速度，并可將鍋爐蒸汽量及蒸汽溫度提高到一個(gè)較高水平，從而可以大大縮短機(jī)組冷態(tài)或熱態(tài)啟動(dòng)時(shí)間。
1.1 During startup or shutdown of boiler, operator may raise temperature and pressure ascending speed to increase load of boiler, and raise the steam volume of boiler and steam temperature to a higher level so as to shorten starting time for machine in cold state and thermal state.
1.2實(shí)現(xiàn)在停機(jī)時(shí)不停爐,以便于在短時(shí)間停機(jī)后,快速使汽機(jī)帶負(fù)荷,避免由于鍋爐重新點(diǎn)火升溫升壓而造成啟動(dòng)延誤。
1.2 Realize shutdown of machine without stopping boiler, so as to avoid delay of startup due to re-ignite and temperature rising in a short duration after shutdown.
1.3一定容量的汽機(jī)旁路可在汽輪機(jī)沖轉(zhuǎn)前使鍋爐煤燃燒率穩(wěn)定在允許的最低負(fù)荷以上運(yùn)行，而不必動(dòng)用燃油系統(tǒng),既可節(jié)省燃油又可提高升溫升壓速度。
1.3 Bypass of steam turbine with certain capacity may allow the boiler to operate with a combustion rate above the lowest load without using fuel system before steam turbine rotating, which saves fuel and raises speed of temperature and pressure ascending.
1.4由于再熱器被高壓旁減溫后的蒸汽冷卻,從而在鍋爐啟停過程中保護(hù)了再熱器。
1.4 Because the reheater is cooled by temperature reducing steam of high pressure bypass, the reheated is protected during the startup and shutdown of boiler.
1.5當(dāng)出現(xiàn)甩負(fù)荷等工況時(shí),旁路能快速打開,從而減少了安全門動(dòng)作次數(shù),不但保護(hù)了安全門的嚴(yán)密性,并可避免主燃料跳閘。
1.5 When load rejection occurs, bypass will open soon so as to reduce action of safety door, which could protect the tightness of safety and avoid tripping of main fuel.
1.6低旁具有快關(guān)功能，當(dāng)凝汽器超溫超壓時(shí)起到保護(hù)凝汽器的作用。
1.6 Low pressure bypass has function of swift shutdown in order to protect steam condenser when temperature and pressure of steam condenser is beyond standard.
1.7機(jī)組正常運(yùn)行時(shí)，旁路系統(tǒng)的自動(dòng)調(diào)節(jié)作用可以有效地防止主蒸汽及再熱蒸汽超壓。
1.7 When the device is operating normally, the automatic adjustment of bypass system will prevent the main steam and regenerated steam surpassing pressure effectively.
二、旁路系統(tǒng)簡(jiǎn)述
II. Description of bypass system
旁路系統(tǒng)可分為汽機(jī)旁路和過熱器旁路。在這里我們著重介紹汽機(jī)旁路的有關(guān)內(nèi)容。
Bypass system is divided into steam turbine bypass and super-heater bypass. We induced relative content about bypass of steam turbine.
汽輪機(jī)旁路一般由高壓旁路和低壓旁路組成，通常串聯(lián)。無論是高旁還是低旁一般都由旁路蒸汽轉(zhuǎn)換閥、噴水調(diào)節(jié)閥自動(dòng)控制系統(tǒng)等組成。必要時(shí)還可增加主蒸汽隔斷閥，減溫水隔斷閥等相關(guān)部件。
Steam turbine bypass is generally made of high pressure bypass and low pressure bypass, series connection is available. Either high pressure bypass or low pressure bypass is composed of bypass steam conversion valve, spray water control valve and so on. Major steam stop valve, attemperation water stop valve and other relevant parts are added when necessary.
其中旁路系統(tǒng)的主要部件為旁路蒸汽轉(zhuǎn)換閥，它是旁路系統(tǒng)的核心，決定了整套裝置的性能和質(zhì)量。旁路蒸汽轉(zhuǎn)換閥通常又被稱為旁路調(diào)節(jié)閥，蒸汽變換閥，減溫減壓閥等等。旁路蒸汽變換閥要求減溫減壓必須在同一閥體內(nèi)完成，壓力對(duì)閥體的要求越厚越好，能更好地承壓，而溫度要求閥體壁越薄越好，才能快速消除溫度應(yīng)力對(duì)閥體造成的傷害，保護(hù)閥體。如果減溫水直接作用于旁路閥閥體或減溫水霧化不徹底，勢(shì)必由于溫度應(yīng)力的原因?qū)е麻y體產(chǎn)生延時(shí)裂紋，事故隱患隨之而產(chǎn)生，系統(tǒng)壽命也將大大縮短。同時(shí)減溫水的霧化方式和效果，也決定了影響著出口蒸汽的品質(zhì)和整套系統(tǒng)的噪音、振動(dòng)、調(diào)節(jié)精度等。因此旁路閥的設(shè)計(jì)制造技術(shù)相當(dāng)關(guān)鍵。
The main parts of bypass system are bypassing steam reversion valve which is the core of bypass system and decides the performance and quality of whole set of device. Bypassing steam conversion valve is usually called bypass regulation valve, steam conversion valve or temperature reducing & pressure reducing valve and so on. Bypassing steam conversion system requires that temperature reducing and pressure reducing should be finished in one valve, as pressure requires thicker valve body to undertake pressure better and temperature requires thinner wall to eliminate damage to valve due to temperature stress for protecting valve body. If attemperation water acts on valve body of bypass valve directly or atomization of attemperation water is not thorough, the valve body will crack because of temperature stress, bringing hidden trouble for safety and reducing service life of system at the same time. Moreover, the atomization pattern and effect of attemperation water will determine steam quality on outlet and noise, vibration and regulating precision of whole system, etc. Therefore, the designing and manufacturing technology of bypass valve is very crucial.
三、結(jié)構(gòu)特點(diǎn)
III. Structural feature
3.1我公司的旁路閥閥體嚴(yán)格按GB10868-89《減溫減壓閥技術(shù)條件》設(shè)計(jì)制造，采用鍛焊結(jié)構(gòu)。
3.1 The bypass valve produced by our company is strictly designed and manufactured according to GB10868-89 “Specifications of the steam converting valve”, with welded structure.
3.2旁路閥采用減溫減壓一體化結(jié)構(gòu)，但減溫減壓分段進(jìn)行的結(jié)構(gòu)形式。整個(gè)減溫減壓可分為四個(gè)階段（詳見產(chǎn)品圖紙）。
3.2.The integrated structure that the bypass valve adopts is temperature reduction and decompression, but the temperature reduction and decompression is in a different period and step. The entire process can be divided into four stages (see products drawing).
3.3當(dāng)蒸汽進(jìn)入閥體時(shí)，先進(jìn)入相當(dāng)于籠罩式減壓閥的閥芯，進(jìn)行第一減壓，在此階段相當(dāng)于減壓閥的減壓過程，在這里我們對(duì)閥體內(nèi)腔作了特殊處理，消除了卡門渦流的和汽蝕產(chǎn)生（與同行廠家的減壓閥結(jié)構(gòu)有較大區(qū)別詳見我公司焊接式減壓閥專利號(hào)ZL0221838.1）。其中籠罩式減壓閥具有調(diào)節(jié)閥、減壓閥和截止閥的三重功效。當(dāng)閥體關(guān)閉時(shí)，內(nèi)活塞相當(dāng)于截止閥閥瓣，從而具有良好的密封性能。由于密封面堆焊了高硬度硬質(zhì)合金，閥門可以達(dá)到零泄漏，而且使用壽命相當(dāng)長(zhǎng)。
閥瓣、閥桿、閥座都采用了優(yōu)質(zhì)耐熱合金材料，并經(jīng)過固熔滲氮等處理。提高了閥桿、閥瓣的硬度和耐磨，可以防止由于熱膨脹閥桿、閥瓣咬死的情況發(fā)生。
3.3.When the steam enters valve body, it enters the valve core equivalent to the shrouding type relief pressure valve, and perform the first depression process, which equivalents to depression course of relief pressure valve in this stages. The special-purpose processing in the inner chamber of valve we adopt here dispels the occurrence of Karmen vortex and cavitation erosion (have a great difference with the pressure relief valve structure of relevant trade, for detail information see the welding type patent ZL0221838.1 of relief pressure valve of our company). The pressure relief valve of shrouding type has the triple function of regulating valve, pressure relief valve and shutoff valve. When the valve body is closed, the interior piston is equivalent to valve flap of shutoff valve, thus have good sealing properties. Because the sealed surface has piled and welded with the high hardness hard alloy, the valve can reach to zero leakage, and the service life is quite long.
Valve flap, the valve stems and valve base all have adopted the high-quality heat-resisting alloy material, and processed with melting and nitriding procedure ,etc. which improved the hardness and wear-resisting of valve stem and valve flap, so as to prevent the occurrence of the valve stem and valve flap blockage due to the situation of thermal expansion.
3.4蒸汽經(jīng)過一次減壓后，到達(dá)閥體下部進(jìn)入減溫階段，在此部位減溫水進(jìn)入閥體。根據(jù)熱力學(xué)計(jì)算，減溫水的噴射速度為18～23.6m/s其霧化效果最佳。為了保證噴射速度控制在此范圍內(nèi)，一方面我們采用了分段式調(diào)節(jié)閥（詳見我公司分段式調(diào)節(jié)閥專利，專利號(hào)ZL01237443.1）控制減溫水的噴射量，另一方面我們采用了環(huán)形噴咀結(jié)構(gòu)。充分保證了減溫水不受上部閥門開度和減溫水壓力的影響，減溫水霧化效果始終處于最佳狀態(tài)。
在此階段國(guó)內(nèi)外產(chǎn)品均采用桿狀噴咀，插入閥體內(nèi)，實(shí)現(xiàn)減溫。環(huán)形噴咀較桿狀噴咀有以下特點(diǎn)：(1)、桿狀噴咀插在閥體內(nèi),自然會(huì)產(chǎn)生卡門渦流和汽蝕現(xiàn)象,給整個(gè)系統(tǒng)帶來了噪音和振動(dòng)。(2)、桿狀噴咀插在閥體內(nèi)長(zhǎng)期振動(dòng)，必然會(huì)影響設(shè)備使用壽命，甚至嚴(yán)重時(shí)，噴咀折斷造成事故。(3)、環(huán)形噴咀由于噴咀孔多面積大，從而大大降低了減溫水的水珠顆粒直徑，比桿狀噴咀更能充分霧化減溫水。同時(shí)，當(dāng)蒸汽需要相同量的減溫水時(shí)，桿狀噴咀的減溫水是線狀注入的，而環(huán)形噴咀的減溫水是面狀噴射的進(jìn)入閥體，從而大大縮短了減溫水的霧化過程。
環(huán)形噴咀的結(jié)構(gòu)形式，其實(shí)早就被國(guó)內(nèi)外專家所認(rèn)識(shí)和接受，但由于長(zhǎng)期以來，環(huán)形噴咀減溫水水室與閥體直接接觸，溫度應(yīng)力無法消除。因此一直不能得到推廣和運(yùn)用。我公司王惠雨教授通過多年的研制和開發(fā)，終于開發(fā)出了減溫水水室與閥體不直接接觸的特殊結(jié)構(gòu)形式。徹底解決了消除溫度應(yīng)力這一難題。并因此而獲得了實(shí)用新型專利（專利號(hào)ZL01237444.X）。
3.4.The steam reach to the bottom body of the valve and enter the temperature reduction stage after depression. The temperature reduction water in this position enters into valve body. According to the calculation of thermodynamics, the spraying speed of temperature reduction water has the best effect of atomizing result in 18- 23.6m/s. For the ensuring spray speed in this range, on one hand we have adopted the segmenting type regulating valve (for detail information see the segmenting type regulating valve patent of our company, patent number ZL01237443.1) to control the spraying amount of temperature reduction water; on the other hand we have adopted the structure of ring nozzle so as to fully guarantee the temperature reduction water is free of valve opening degree and temperature reduction water pressure influence. The effect of temperature reduction water atomizing result may maintain in best state all the time.
The domestic and international products of this stage usually adopt the form of rod shape nozzle; insert into the valve body and realize temperature reduction. The ring nozzle has the following feature compared with the rod shape nozzle: (1). the rod shape nozzle inserting in the valve body, and emerge the phenomenon of Karmen vortex and cavitation erosion naturally , which brought the noise and vibration to the whole system. (2). the rod shape nozzle shaking for a long time in the valve body will inevitablely influence equipment service life, the break of rod shape nozzle may cause the accident in a serious condition. (3). The ring shape nozzle reduced the diameter of water drop particle of temperature reduction water in a considerable degree, which may realize the fully atomizing result compared with rod shape nozzle. Meanwhile, when the steam needs the same quantity of temperature reduction water, the temperature reduction water of rod shape nozzle is linear to pour into, and the temperature reduction water of ring shape nozzle is flat spraying, so as to shorten the atomized course of reducing the temperature reduction water greatly .
In fact the structure form of ring shape nozzle has already known and accepted by the domestic and international expert. However, it can not be popularized and applied in application all the time. due to the reason that the temperature stress can not be eliminated because the contacting of rod shape nozzle temperature reduction water and valve body. Wang Hui, rain professor of our company finally developed special structure form in which the temperature reduction water and valve body were not contact directly through the years of research and development, which Have solved this difficult problem of the temperature stress elimination completely.
