Abstract

本实用新型公开了一种高压卧立两用止回阀。它由阀体、阀座、阀瓣、弹簧组成,阀体内设有弹簧,弹簧上有阀瓣,阀体两端为法兰,阀座压住阀瓣并嵌入阀体内,它们之间设有密封圈。本实用新型将阀座与阀体的螺纹连接改为压入式,阀体两端为法兰式,因而使阀体的长度变小,使密封性能大大提高,同时安装、维修也更加方便。

Description

高压卧立两用止回阀
本实用新型涉及工业管道或各种泵上使用的高压止回阀,特别适用于油气田开采中的污水、蒸汽、原油、石油新产品输送的高压工业管路及各种地面及油田注水井井口。
目前在油气田的高压注水泵出口处和注水井口使用的是专利号为92222105.7高压止回阀,这种止回阀可立、卧式或随意方位安装,检修更换阀瓣、阀座方便,并且密封性能好、阀瓣开启迅速灵活、使用寿命长,但这种止回阀阀座与阀体之间螺纹连接,阀体与管路之间为卡扣式,因而阀体过长这就要求在安装时管路之间要留有相当大的空隙,而许多管路之间的空隙很小,因而在安装时带来了很大的不便。
本实用新型的目的在于克服现有技术的缺点,提供一种高压卧立两用止回阀。
本实用新型的目的是这样实现的:高压卧立两用止回阀由阀体、阀座、阀瓣、弹簧组成,阀体内设有弹簧,弹簧上有阀瓣,阀体两端为法兰,阀座压住阀瓣并嵌入阀体内,它们之间设有密封圈。
本实用新型将阀座与阀体的螺纹连接改为压入式,因而使阀体的长度变小,便于安装,同时密封性能也大大提高,安装、维修也更加方便。
下面结合附图对本实用新型作进一步描述:
图1为高压卧立两用止回阀的结构示意图;
图中:1-阀体、2-阀座、3-阀瓣、4-弹簧、5-密封圈;
如图1所示,高压卧立两用止回阀由阀体1、阀座2、阀瓣3、弹簧4组成,阀体1两端为法兰,阀体1内设有弹簧4,弹簧4上有阀瓣3,阀座2压住阀瓣3并嵌入阀体1内,它们之间设有密封圈5。
高压止回阀由原来的卡扣式安装变成法兰式,阀座2与阀体1由原来的螺纹连接变成压入式,这样对管路之间的缝隙要求不是很高,因而使安装、维修更加容易,密封更加可靠。
