UJ41H柱塞截止阀

UJ41H柱塞截止阀一、柱塞截止阀结构及工作原理：     柱塞式截止阀是由阀体、阀盖、阀杆、柱塞、密封圈、手轮等零七八碎件组成（如图）。当旋转手轮时，通过阀杆带动柱塞，使柱塞顶斜锥面与阀座锥面往复离合，完成阀门的开启和关闭。
    在阀门中，柱塞与密封圈间采用过盈配合。通过调节阀盖固定螺栓的压紧，使密封圈被压缩，内圈紧包柱塞外圈紧贴阀腔内壁，这样在密封圈上所产生的径向分力将在于流体的压力，从而保证了密封性，杜绝了外泄漏。
    由于密封圈采用回弹性强，而靡性高的无毒新型密封材料，所以密封可靠、经久耐用。阀座与柱塞的锥面密封部位，采用优质耐靡材料，能保证阀门的使用寿命。
    本阀门结合柱塞阀的无泄漏优点和截止阀的启闭快特点，成为一个结构新颖、用途广泛的新品种。

YJ41W氧气截止阀不锈钢截止阀

YJ41W氧气截止阀不锈钢截止阀氧气截止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六时，操作力所需要克服的阻力，是阀杆和填料的磨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，法兰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，一律采用自上而下。
　　氧气截止阀开启时，阀瓣的开启高度，为公称直径的25%～30%时，流量已达到最大，表示阀门已达全开位置。所以截止阀的全开位置，应由阀瓣的行程来决定。氧气截止阀具有以下优点：　 1、结构简单，制造和维修比较方便。
2、工作行程小，启闭时间短。
3、密封性好，密封面间摩擦力小，寿命较长。氧气截止阀主要性能和使用范围：型号公称压力壳体试验压力Ps(Mpa) 气密封试验适用温度(℃) 适用介质水气 YJ41W-25P
