一、美标对夹凸耳止回阀产品简介:
H76型凸耳对夹双瓣旋启式止回阀(美标)
H76 type lug
and wafer type double discs swing check valve(ANSI standard)
二、美标对夹凸耳止回阀概述:
H76型凸耳对夹双瓣式止回阀用于管路系统中。该阀流道通畅阻力小,动作灵敏,密封性能好。其主要作用是防止介质倒流、防止泵及其驱动电动机反转,以及容器内介质的泄放。所以被广泛应用于化工、医药、食品、市政水力等行业。该阀安装位置不受限制,通常安装于水平管路上,但也可以安装于垂直管路或倾斜管路上。
三、美标对夹凸耳止回阀工作原理:
H76型凸耳对夹双瓣式止回阀开启时,靠介质的工作压力把阀瓣冲开,此时阀门开启,介质通过;关闭时,靠介质逆流和阀瓣的自重,阀瓣绕阀体内转轴旋转,从而使阀瓣和阀座密合,达到关闭止回阀的目的。
四、美标对夹凸耳止回阀结构特点:
H76型凸耳对夹双瓣式止回系列阀门主要由阀体、阀瓣、阀杆及弹簧等结构组成。由于阀体的结构短、重量轻,阀瓣关闭行程短关闭迅速,减少水锤水击等特点。阀瓣为半圆双瓣结构,可绕阀体内的转轴旋转,转轴的轴线必须和阀体密封面在一个平面上,保证关闭时达到密封。连接方式:采用了对夹凸耳结构,可使阀体外形更加美观、休积小、重量轻。
五、美标对夹凸耳止回阀技术参数:
