BURKERT塑料阀体球阀,BURKERT塑料膜片阀,德国BURKERT球阀
BURKERT塑料阀体球阀属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。当介质由阀瓣下方进入阀门时，操作力所需要克服的阻力，是阀杆和填料的摩擦力与由介质的压力所产生的推力，关阀门的力比开阀门的力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。近年来，从自密封的阀门出现后，截止阀的介质流向就改由阀瓣上方进入阀腔，这时在介质压力作用下，关阀门的力小，而开阀门的力大，阀杆的直径可以相应地减少。同时，在介质作用下，这种形式的阀门也较严密。我国阀门“三化给”曾规定，截止阀的流向，律采用自上而下。本阀要水平安装截止阀开启时，阀瓣的开启高度，为公称直径的25%～30%时，流量已达到zui大，表示阀门已达全开位置。
