Abstract

直角截止阀、止回阀阀座,属阀门制作技术领 域。主要由金属外环(1)和非金属软密封内环(2)构 成,外环(1)位于阀体(5)与管道法兰(3)之间,用螺栓 (4)固定联接,内环(2)安装在外环(1)的凹槽内。使 用时,阀头(6)锥面与内环(2)锥面接触,实现可靠密 封。

Description

直角截止阀、止回阀阀座,属阀门制作技术领域。
现有技术中的直角截止阀、止回阀,阀体与阀头大都整体采用金属制作,密封性能取决于两者接触处起密封作用部位的加工精度,要想使密封性能好,加工精度要求高,成本增加。
本实用新型的目的是使阀体密封可靠,且加工简单、成本低。
本实用新型是通过如下技术方案实现的:该阀座主要由金属外环和非金属软密封内环组成,外环位于阀体与管道法兰之间,由螺栓固定连接,外环上开有凹槽,内环安装在外环凹槽内。关闭阀门时,阀头锥面与安装在外环凹槽内的软密封内环锥面相接触,实现可靠的密封。
下面,结合附图及实施例,详述本实用新型。
图1,本实用新型主视剖视图。
本例主要由金属外环(1)和非金属软密封内环(2)组成,本例中的内环(2)采用橡胶或聚四氟乙烯等弹性材料制成,外环(1)位于阀体(5)与管道法兰(3)之间,用螺栓(4)固定连接,外环(1)上开有凹槽,内环(2)安装在外环(1)的凹槽内。关闭阀门,阀头(6)锥面与内环(2)锥面相接触,可以实现可靠的密封。
由于本实用新型在阀座上安装了软密封内环(2),使阀头(6)的锥面可直接与内环(2)锥面接触,可以实现可靠的密封。

Claims (2)

1、直角截止阀、止回阀阀座,由金属外环(1)和软密封内环(2)组成,其特征是外环(1)位于阀体(5)与管道法兰(3)之间,用螺栓(4)固定连接,外环(1)上开有凹槽,内环(2)安装在外环(1)的凹槽内。
2、根据权利要求1所述的直角截止阀、止回阀阀座,其特征是所说的内环(2)可用橡胶或聚四氟乙烯等弹性材料制成。
