進(jìn)口不銹鋼螺紋球閥
德國(guó)托普進(jìn)口不銹鋼螺紋球閥應(yīng)用領(lǐng)域:
適用于化工、石油、天然氣、冶金、等行業(yè)及含硫化氫介質(zhì)、雜質(zhì)多、腐蝕嚴(yán)重的天然氣
進(jìn)口不銹鋼螺紋球閥結(jié)構(gòu)：
1.閥門全開、全關(guān)位置的鎖緊裝置：為防止啟、閉閥門的誤動(dòng)作，在全開、全關(guān)位置設(shè)置有鎖定孔。可將閥門位置鎖定，以防止其他人誤動(dòng)，以及震動(dòng)等原因引起的閥位誤動(dòng)，保證設(shè)備的安全。
2.閥桿防飛結(jié)構(gòu)：閥桿的下部設(shè)計(jì)凸肩，裝配時(shí)將閥桿從閥體內(nèi)部下裝，防止閥內(nèi)壓力生高閥桿飛出。同時(shí)也可以在意外火災(zāi)后，閥桿與閥體的密封性能。
3.防靜電的機(jī)能：在使用于可燃性介質(zhì)如燃點(diǎn)較低的汽油、天燃?xì)狻⒈榈纫兹冀橘|(zhì)時(shí)，應(yīng)考慮防止靜電的問題，以避免因球體與聚四氟乙烯閥座間的摩擦產(chǎn)生靜電而產(chǎn)生爆炸。
4.防火結(jié)構(gòu)：當(dāng)發(fā)生意外火災(zāi)時(shí)，閥座、填料、墊片等非金屬材料被燒毀，為阻止介質(zhì)的大量泄漏，設(shè)計(jì)了防火的密封結(jié)構(gòu)。
The locking device 1 the valve is fully open and fully closed position to prevent misoperation of opening and closing the valve, a locking hole is arranged on the fully open and fully closed position. The position of the valve can be locked to prevent other people from moving, as well as the vibration caused by the valve position error, to ensure the safety of equipment.
2 stem anti fly structure: the lower design shoulder of the stem, the assembly will stem from internal under pressure in the valve body, to prevent the high blow out. At the same time, it can also be in the event of fire, the valve stem and valve sealing performance.
3 anti-static function: in use in flammable medium such as low burning gasoline, natural gas, propane and other combustible materials, should be considered to prevent electrostatic problems, to avoid static friction for sphere and PTFE seat between the explosion.
4 fire protection structure: when accidental fire, the valve seat, packing, gasket and other non-metallic materials were burned, in order to prevent a large number of media leakage, the design of the fire sealing structure.
