进口燃气截止阀

 

德国巴赫进口燃气截止阀概述：Overview of Bach imported gas globe valve in germany:

进口燃气截止阀属于燃气阀门中的一种，也可称液化气截止阀(液化气阀门)。本产品有耐压、耐腐蚀作用，使用于城市液化气石油气贮备站，也使用于炼油厂、石油化工厂、石油化工厂的液化气系统，作为控制介质截的启闭装置。

Imported gas cut-off valve is a kind of gas valve, also known as liquefied petroleum gas stop valve (liquefied petroleum gas valve). This product has the function of pressure resistance and corrosion resistance. It is used in the liquefied petroleum gas storage of the city, and also used in the liquefied petroleum gas system of the refinery, petrochemical plant and petrochemical plant, as the cool device of the cutting and closing of the dielectric section.
进口燃气截止阀采用成形聚四氟乙烯/柔性石墨作为密封填料，由填料压盖提供初始密封，当发生磨损引起的动密封泄漏时，可用填料压盖螺母进行调整，适用于大多数高中压非腐蚀性流体输送场合。在阀瓣的金属密封面上设置一沟槽，镶装一软密封环与阀座金属密封面形成软硬双重密封结构，提高了密封性能，避免了金属密封旋转摩擦产生静电，引起的火花。金属硬密封面保护软密封材料过载不受损，延长阀门使用寿命。适用于石油、化工、钢铁、水力、电力等行业。阀座密封面材料为尼龙塑料。

进口燃气截止阀的定义：Definition of imported gas globe valve:

1、手轮顺时针方向转时,阀杆向下移动,阀瓣下降使密封面密合,将通路切断.逆转时则开启,阀杆提到较高点上密封起作用。   
2、本阀门增加了一个上密封.在阀门开启状态时,与填料一起两层密封作用,并对填料有一定的保护作用  
3、本阀门采用尼龙制品作密封面,填料为软成形填料,上密封也为软材质,密封性能较好。
4、填料密封性能随介质压力上升而增强，即具有自密封性能，无需人工维护。
5、防火结构：当软密封材料被烧坏后，金属密封面仍能保持密封，避免火灾扩大。
6、采用弹性V形聚四氟乙烯或丁qing橡胶作为动密封填料，由填料盖、不锈钢弹簧提供初始密封。
7、阀座密封面材料为尼龙塑料提高了密封性能，避免了金属密封旋转摩擦产生静电，引起的火花。
8、防静电结构：当阀门的内密封体旋转摩擦产生静电时，利用一个导电装置和大地连通，从而避免静电导致天然气火灾。
9、当阀门外部失火时，软密封材料被高温烧毁，其金属密封仍能保证阀门紧闭密封，从而形成了软硬双重密封结构，密封性能好。

The definition of imported gas valve:

2、1, hand wheel clockwise rotation, the valve stem to move down, the valve flap to close the sealing surface, cut off the path. When the reverse is open, the valve stem to mention the highest point on the seal effect.    

3、2, the addition of a valve on the seal. In the valve open state, and filling the role with two seals, and the protective effect of on the filler

4、3, the valve with nylon products for sealing cover, packing for the soft forming filler, the seal is also soft material, sealing performance is better.

5、4, the sealing performance of the media with the increase in pressure, which has self sealing performance, without manual maintenance.

6、5, fireproof structure: when the soft sealing material is burned, the metal sealing surface can remain sealed, avoid the spread of fire.

7、6, using elastic V shaped Teflon or nitrile rubber as sealing filler, the filler cap, stainless steel spring provides initial seal.

8、7, the valve seat sealing surface material for nylon plastic to improve the sealing performance, to avoid the metal seal rotary friction produce static electricity, caused by sparks.

9、8, anti-static structure: when the valve inside the seal body to produce static friction rotation, the use of a conductive device and the earth to connect, so as to avoid static electricity caused by natural gas fire.

10、9, when the valve outside the fire, the soft sealing material was burned at high temperature, the metal seal can still ensure that the valve closed and sealed, thus forming a double seal structure of hard and soft, good sealing performance.
