進口不銹鋼螺紋球閥|進口螺紋不銹鋼球閥
德國托普進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、腐蝕嚴重的天然氣
進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、閉閥門的誤動作,在全開、全關(guān)位置設(shè)置有鎖定孔??蓪㈤y門位置鎖定,以防止其他人誤動,以及震動等原因引起的閥位誤動,保證設(shè)備的安全。
2.閥桿防飛結(jié)構(gòu):閥桿的下部設(shè)計凸肩,裝配時將閥桿從閥體內(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.防靜電的機能:在使用于可燃性介質(zhì)如燃點較低的汽油、天燃氣、丙烷等易燃介質(zhì)時,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,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.
