Abstract

一种自力式微压调节阀,包括阀体、阀座、阀杆、指挥器活塞、指挥器弹簧座,其主要技术特征是阀杆阀头端与阀座密封为四氟橡胶密封圈,所述四氟橡胶密封圈的截面为圆锥形;所述四氟橡胶密封圈与阀座之间还设有补偿垫圈。本实用新型采用四氟橡胶密封圈,并加装补偿垫圈,使阀门增加压力平稳,阀后压力缓冲小且无气体泄漏现象。

Description

自力式微压调节阀
技术领域
本实用新型涉及一种自力式微压调节阀,特别是指阀门密封结构的改进。
背景技术
自力式微压调节阀主要用于工业炉火天然气点火系统,起到减压稳压作用,以前在阀门内部采用不锈钢硬密封,容易产生在生产停止使用时阀后压力升高安全阀起跳现象,容易出现危险,因为硬密封在管路有焊渣和杂质的情况下会产生泄漏。
发明内容
本实用新型提供一种增加压力平稳,阀后压力缓冲小且无气体泄漏的自力式微压调节阀。
本实用新型是通过如下技术方案来实现的:一种自力式微压调节阀,包括阀体、阀座、阀杆、指挥器活塞、指挥器弹簧座,其主要技术特征是阀杆阀头端与阀座密封为四氟橡胶密封圈,所述四氟橡胶密封圈的截面为圆锥形;所述四氟橡胶密封圈与阀座之间还设有补偿垫圈。
本实用新型采用四氟橡胶密封圈,并加装补偿垫圈,使阀门增加压力平稳,阀后压力缓冲小且无气体泄漏现象。
附图说明:
图1为本实用新型的结构示意图。
具体实施方式:
如图1所示,本自力式微压调节阀,包括阀体1、阀座2、阀杆5、指挥器活塞6、指挥器弹簧座7,阀杆阀头端与阀座密封为四氟橡胶密封圈3,所述四氟橡胶密封圈的截面为圆锥形;所述四氟橡胶密封圈与阀座之间还设有补偿垫圈4。
本实用新型采用四氟橡胶密封圈,并加装补偿垫圈,使阀门增加压力平稳,阀后压力缓冲小且无气体泄漏现象。

Claims (2)

1.一种自力式微压调节阀,包括阀体、阀座、阀杆、指挥器活塞、指挥器弹簧座,其特征在于阀杆阀头端与阀座密封为四氟橡胶密封圈,所述四氟橡胶密封圈的截面为圆锥形。
2.如权利要求1所述的一种自力式微压调节阀,其特征在于所述四氟橡胶密封圈与阀座之间还设有补偿垫圈。
