阀门可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。
用于流体控制系统的阀门，从最简单的截止阀到极为复杂的自控系统中所用的各种阀门，其品种和规格相当繁多。
煤化工领域由于氧气工况安全事故多发，且极易造成巨大的人身安全或经济财产损失，因此对氧气工况用阀门设立了远高于一般行业标准的技术与质量要求。
《煤化工设备推荐手册》推荐了上海科科阀门、苏州纽威阀门、上海开维喜、中核苏阀、浙江超达、上海精工等厂家阀门，煤化工领域国产阀门也有应用实践。
1 适用于煤化工严苛工况的几种阀门1.1 氧气切断球阀煤化工领域中的氧气切断球阀必须达到的要求：（1）严格脱油脱脂：密封等级高达ANSI B16.104 VI 级/API 598 （双向）；（2）温度要求高：煤气化工艺靠近气化炉的主氧路最后一个氧气切断阀，要求使用温度高达500 ℃；（3）压差大：氧气放空阀、氧气旁通阀，开启瞬间的压差达到4.7~8.6 MPa，造成阀门开启需要的扭矩大，氧气流速高，要求对于阀门内件的材料选择高；（4) 开关时间要求高：煤气化工艺中的主氧路阀门开关时间要求开关时间较短，尤其阀门关闭时间一般都要求<3 s；（5）密封副表面合金高：球体与阀座之间的摩擦属于干摩擦，容易造成阀门开关不流畅，表面合金容易剥落，这就要求球体与阀座表面为硬化合金。

A set of Belleville-Spring Washers are used on each gland stud to help exert a continuous compressive force on the gland follower flange and therefore reduce fugitive emissions from the stem packing. NEWAY standard Belleville-Spring Washers are protected by a weatherproof cap to keep them free from environmental contamination, resulting in a longstable life.The packing set is a combination of parallel and vertical layer sealing elements, which are made of expanding graphite in die-formed rings and have features of heat resistance, less stress relaxation and low creep. With this special structure, it allows for a low-friction on rotary & rising stem valves, therefore providing the stabilized seal performance for long cycle life.For medium and low temperature service, the standard V shape PTFE packing rings are installed for lowemission control.Floating Ball Valve Design FeatureLow Emission Control2963161861171514128137541110Series FE1 Ball ValveRegular port, uni-body, end entry designBlow-out Proof StemInternally inserted and functions as the backseat for assured stem sealing at all pressuresMetal-to-Metal Sealing When non-meatl sealing is deteriorated by fire,ball floats to shut off the line fruidEmission-free Graphite primary gasketIndex noPart123456789Index no PartBody Closure BallGland Flange Lever Seat Ring Stem Gland Gasket101112131415161718Grounding Washer Packing Set Stop Plate Thrust Washer Retainer Washer Bolt Rotaining SpringSeries FE1 Ball ValveSeries FE1 Ball ValveRegular port,uni-body,cast steel,end entry designClass 150LBWeight KgW mmH mmL mmD mmd mmSizeinDimensionsWW DLdHWDLddHGear Operator1 / 22 3101 / 23 / 411-1/222-1/23468101 / 23 / 49.512.71930385164761141441879.512.712.71925.43851647610215220325412.719108117127165178191203229267292330140152545964901021121211662082463035459120140140160265265265300400 300 * 400 *120140 1.72.72.985.008.7112.416.6624.38541011502.83.61638111071817962416135151412Series FB2 Ball Valveavailable in size from to 12 full port or witnessed and certified by Lloyd s Register.Double "D" Stem HeadProvides mounting of the lever handle alwaysin parallel to the flow passage Blow-out Proof Stem Internally inserted and functions as the backseat for assured stem sealing at all pressuresEmission-free Graphite primary gasket Metal-to-Metal SealingWhen non-meatl sealing isdeteriorated by fire,ball floats to shut off the line fruid easily for installation of gear, motor or pneumatic actuator 123456789Body Closure Ball Yoke Gland Flange Seat Ring Stem Gland Gasket 101112131415161718Grounding Washer Packing Set Thrust Washer Stud Nut Bolt Bolt Spring Steel BallSeries FB2 material specifications Series FB2 Ball Valve Two-piece,split body,cast steel,side entry design Full Port Size in D mm L mm H mm W mm Weight Kg Reduced Port Size in D mm L mm H mm W mm Weight Kg d mm 150L B Gear Operator Dimensions W H D L Full Port WH d D L Reduced Port W 123456789101112131415161718No. Part Standard Stainless Steel Sour Service Low TemperatureServiceASTM A352-LCB ASTM A352-LCB ASTM A182-F316ASTM A216-WCB ASTM A216-WCB PTFE ASTM A182-F316ASTM A182-F316316SS + Graphite Graphite PTFE PTFE ASTM A320-L7M ASTM A194-7M ASTM A320-L7M ASTM A320-L7M S.S.S.S.ASTM A216-WCB ASTM A216-WCB ASTM A105/ENP ASTM A216-WCB ASTM A216-WCB PTFE ASTM A182-F6a ASTM A276-420316SS + Graphite Graphite PTFE PTFE ASTM A193-B7M ASTM A194-2HM ASTM A193-B7M ASTM A193-B7M S.S.S.S.ASTM A351-CF8M ASTM A351-CF8M ASTM A182-F316ASTM A351-CF8M ASTM A351-CF8M PTFE ASTM A182-F316ASTM A182-F316316SS + Graphite Graphite PTFE PTFE ASTM A193-B8ASTM A194-8ASTM A193-B8ASTM A193-B8S.S.S.S.ASTM A216-WCB ASTM A216-WCB ASTM A105/ENP ASTM A216-WCB ASTM A216-WCB PTFE ASTM A182-F6a ASTM A276-420316SS + Graphite Graphite PTFE PTFE ASTM A193-B7ASTM A194-2H ASTM A193-B7ASTM A193-B7S.S.S.S.Body Closure Ball Yoke Gland Flange Seat Ring Stem Gland Gasket Grounding Washer Packing Set Thrust Washer Stud Nut Bolt Bolt Spring Steel Ball 1 / 23 / 411-1/222-1/23456810121 / 2131925385164761021251522032543051310811712716517819120322935639445753361014059637697107142152178252272342345479591301301602302304004007001100 300 * 300 * 400 * 600 *1303/4*1/2*3/43/4*1/2*3/41*3/4*11-1/2*1-1/22*1-1/2*22-1/2*2*2-1/23*2-1/2*34*3*46*4*68*6*810*8*1012*10*121.782.003.517.2311.0515.022.036.058.0110.0195.0309.0346.02.29131925385164761021522032541319253851647610215220325430519117127165178190203229394457530610152828510011512015316219129034044282130130160230230400400460 300 * 300 * 400 *130 3.04.57.09.515.016.029.548.0123.0212.0230.03.5Series FB2 Ball Valve122019178111354197161021181631415296Blow-out Proof Stem Internally insertedand functions as the backseat for assured stem sealing at all pressuresSeries FB2 Ball Valve Two-piece, split body, forged steel, side entry design This series ball valves are featured with two-piece bolted with flanged end body and floating ball.

When the sealing materials (seat sealing or stemo-ring) are damaged or decomposed by fire or otheraccidental causes, leakage from the seat and stem can beprevented by injection of sealant into these fittings. Fitting isalso internally installed a second check valve to providesbackup sealing. Emergency sealant injection system Cavity Pressure ReliefEach ball seats shut off the line fluid independently on the upstream and downstream side, allowing double block o p e r a t i o n. W h e n t h e p r e s s u r e i s simultaneously applied to both sides of the ball in closed position, the valve bore and the body cavity will be isolated from each other, and the residue within the body cavity can be released through the drain plug.Double block and bleed Top flange Injection Closure Gland Body Ball SeatThe stem is made separately from the ball; The lover end of the stem is designed with an integral collar to be blowout-proof.Antistatic device is a standard feature of NEWAY ball valve . A spring-loaded pin assures the electrical continuity, between ball ,stem and body, so as to avoid sparks during turning of the stem to open and close the valve, which could be dangerous in caseof hazardous area installation.Super Fire safe designExternal leakage preventionLeakage from the valve stem area isprevented by double sealing with 2 O-rings and gland gasket. Leakagethrough the valve body joint is alsoblocked by double sealing with O-ringand body gasket. After a fire hasdeteriorated O-rings, gland gasket,body gasket and stem firesafe packingare the measure that prevents externalfluid leakage. When non-metal materials such as O-ring, seat insert and spacer aredecomposed or deteriorated by fire, theedge of the metal seat preloaded by theBall to shut off the line fluid to minimize internal leakage through the valve bore.

硬密封球阀球体工艺流程
硬密封球阀球体工艺流程英文回答：The manufacturing process of a hard-sealed ball valve involves several steps to ensure the quality and functionality of the valve. Here, I will walk you through the process in detail.1. Material Preparation: The first step is to prepare the materials required for the ball valve. This typically involves selecting a suitable metal alloy for the valve body and ball, such as stainless steel or carbon steel. The materials are then cut and shaped into the desired sizes.2. Machining: Once the materials are prepared, machining processes are carried out to create the necessary features on the valve body and ball. This includes drilling holes for the inlet and outlet ports, as well as machining the ball to achieve the desired shape and dimensions.3. Welding: In some cases, the valve body and ball may need to be welded together. This is done using specialized welding techniques to ensure a strong and leak-proof joint. The welded parts are then carefully inspected for any defects.4. Surface Treatment: After the machining and welding processes, the valve body and ball undergo surface treatment to enhance their corrosion resistance and improve their appearance. This may involve processes such as polishing, plating, or coating.5. Assembly: Once all the individual components are ready, they are assembled together to create the complete ball valve. This includes attaching the valve stem, handle or actuator, and any necessary seals or gaskets. The assembly is done with precision to ensure smooth operation and proper sealing.6. Testing: Before the ball valves are ready for use, they undergo rigorous testing to ensure their performance and reliability. This includes pressure testing to checkfor leaks, as well as functional testing to ensure smooth operation and proper sealing.7. Packaging and Shipping: Finally, the finished ball valves are packaged and prepared for shipping to the customers. They are carefully packed to prevent any damage during transportation.中文回答：硬密封球阀的制造过程包括多个步骤，以确保阀门的质量和功能。
