Abstract

一种能关闭、调整流量,同时能起止回作用的阀门。由手轮、阀杆、导向孔、导向杆、密封压盖、回位弹簧、阀板、阀体、密封面组成,其特征是:阀杆中心加工有导向孔,导向孔内安装有导向杆,导向杆和阀板连接为一体。当阀门开启时,如介质方向按正常方向流动,阀板在介质的推力下打开,如介质反方向流动,阀板在重力和回位弹簧的作用下自动关闭阀门。

Description

止回截止一体阀
所属技术领域
本实用新型涉及工业和民用管道设计,尤其是化工、火电、民用水泵房等设备机房。
目前,公知的止回阀和截止阀均是独立单体设计、安装.这样即占用空间(设备机房通常设备、管道、阀门、仪表、支架等比较集中)又浪费材料(除阀体外多法兰、螺栓、密封垫、支架等).而且多一道连接就多一次泄漏的可能性.
发明内容
本实用新型阀门同时具有止回阀和截止阀作用.
本实用新型解决其技术问题所采用的技术方案是:与传统的截止阀相比,在阀杆中心加工有导向孔,导向孔内安装有导向杆,导向杆可以在导向孔内上下自由移动,导向杆和阀板连为一体,在阀杆外围阀板和密封压盖之间安装有回位弹簧,当阀门关闭时,阀板在阀杆的压力下关闭密封.当阀门开启时,如介质方向按正常方向流动,阀板在介质的推力下打开,介质通过.如介质反方向流动,阀板在重力和回位弹簧的作用下自动关闭阀门.
本实用新型的有益效果是,单独一个阀门既能实现介质流量大小的调节又能起到单方向控制.
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是本实用新型止回截止阀开启状况图。
图2是本实用新型止回截止阀自动关闭状况图。
图1中:1.手轮,2.阀杆,3.导向孔,4.导向杆,5.密封压盖,6.回位弹簧,7.阀板,8.阀体,9.密封面.
具体实施方式
在图1为阀门开启状态,介质从阀门左侧向右侧流动,在密封面(9)位置是从下向上流动,此时阀板(7)在介质推力下克服回位弹簧(6)的压力被打开。为了减少对介质压力的影响,回位弹簧(6)选用弹力参数较小的弹簧。
图2为阀门自动关闭状态,介质流向改变,从阀门右侧向左侧流动,阀板(7)在重力和回位弹簧(6)的作用下,回位到密封面(9)位置关闭阀门,有导向杆(4)确保阀板(7)回位位置,这样起到介质单方向控制。
当旋转手轮(1)使阀杆(2)向下顶住阀板(7)至密封面(9)时,阀门处于人为关闭状态。
