  电竞必威的详细资料:

一、电竞必威特点

(1)电竞必威结构比betway简单,制造与维修都较方便。   

(2)密封面不易磨损及擦伤,密封性好,启闭时阀瓣与阀体密封面之间无相对滑动,因而磨损与擦伤均不严重,密封性能好,使用寿命长。   

(3)启闭时,阀瓣行程小,因而必威高度比betway小,但结构长度比betway长。   

(4)启闭力矩大、启闭较费力,启闭时间校长。   

(5)流体阻力大,因阀体内介质通道较曲折,流体阻力大,动力消耗大。

(6)介质流动方向 公称压力PN16MPa时,一般采用顺流,介质从阀瓣下方向上流;公称压力PN20MPa时,一般采用逆流,介质从阀瓣上方向下流.以增加密封件能。使用时,必威介质只能单方向流动,不能改变流动方向。

二、电竞必威执行标准

设计规范:GB/T 12235

结构长度:GB/T 12221

法兰连接:JB/T 79

试验与检验:JB/T 9002
