?J941H-16C?DN125玉林电动截止阀

J941H电动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，一律采用自上而下。

结构特点

1、选材考究，符合国内、外相关标准，结构合理，造型美观。

2、阀瓣、阀座密封面采用铁基合金堆焊或司太立（Stellite）钴基硬质合金堆焊而成，耐磨、耐高温、耐腐蚀、抗擦伤性能好，使用寿命长。

4、阀杆经调质及表面氮化处理，有良好的抗腐蚀性和抗擦伤性。

5、可采用各种配管法兰标准及法兰密封面型式，满足各种工程需要及用户要求。

6、阀体材料品种齐全，填料、垫片可根据实际工况或用户要求合理选配，能适用于各种压力、温度及介质工况。

7、倒密封采用螺纹连接密封座或本体堆焊奥氏体不锈钢而成，密封可靠，更换填料可在不停机情况下进行，方便快捷，不影响系统运行。

8、配有DZW系列多回转式电动装置，具有壳体小，重量轻，功能全，并可与远程电脑配套使用，也可按用户要求选配电动装置。
