Description

一种新型止回阀 
技术领域
本实用新型涉及阀门技术领域,尤其是一种新型止回阀。 
背景技术
传统的止回阀为防止介质回流而设计的止回阀,但在高温高压下橡胶密封容易泄漏,从而失去了止回效果,而且在腐蚀性强的高温高压下,弹簧两头最易腐蚀,造成弹簧容易断裂,橡胶软密封也容易失效,使阀门容易失效。 
实用新型内容
一种新型止回阀,其特征在于,包括:阀体1、止回阀板2、阀套3、四氟密封4、止回弹簧5、连接套6、阀盖7、阀杆套8,所述一种新型止回阀是设有四氟密封4,所述一种新型止回阀是设置有止回弹簧5,所述四氟高分子密封4是设置在通过介质方向的止回阀板2的正面,防止阀腔泄露和腐蚀。所述止回弹簧5两头设置有阀套3和阀杆套8,使止回弹簧5得到阀套3和阀杆套8的保护,避免了弹簧两头薄弱处最容易腐蚀处,腐蚀断裂,造成阀门失效。 
本实用新型的有益效果是:1.强化耐腐蚀效果;2.避免了弹簧断裂;3.节省材料达到节能效果。 
附图说明
图1是一种新型止回阀结构示意图 
阀体1、止回阀板2、阀套3、四氟密封4、止回弹簧5、连接套6、 阀盖7、阀杆套8 
具体实施方式
图1所示,所述一种新型止回阀在止回阀板2的阀板面设有四氟密封4,所述四氟密封4设置在止回阀板2的正面,就是面向介质的方向,防止阀腔泄露和腐蚀。所述止回弹簧5两头,得到阀套3和阀杆套8的保护,所述止回弹簧5上端设置有阀杆套8与之相连,避免了弹簧两头薄弱处最容易腐蚀处,腐蚀断裂,造成阀门失效。
