Abstract

一种双向安全止回阀，其腔体内设主封闭板总成B，主封闭板总成B连接有弹簧B，在主封闭板总成B下有一密封面、薄弱断裂处和打开支架，腔体下方轴连接弹簧A和主封闭板总成A。本装置有用加油领域，可以实现油路双向止回，防止液体倒流。

Description

一种双向安全止回阀
【技术领域】
本发明涉及一种加油设备的止回阀，具体涉及一种双向安全止回阀。 
【背景技术】
止回阀(Check Valve)是能自动阻止流体倒流的阀门。止回阀的阀瓣在流体压力作用下开启，流体从进口侧流向出口侧。当进口侧压力低于出口侧时，阀瓣在流体压差、本身重力等因素作用下自动关闭以防止流体倒流。现有的止回阀仅能保证单向止回。 
【发明内容】
为了克服现有的技术的不足，本发明提供一种双向安全止回阀，可以实现双向止回，防止安全阀内液体倒流或向外喷出。 
本发明所采用技术方案是：一种双向安全止回阀，其腔体内设主封闭板总成B，主封闭板总成B连接有弹簧B，在主封闭板总成B下有一密封面、薄弱断裂处和打开支架，腔体下方轴连接弹簧A和主封闭板总成A。 
当薄弱断裂处受冲击断裂后，打开支架与主封闭板总成B脱离，使主封闭板总成B在弹簧B作用下向下移动，主封闭板总成B移动到关闭状态位置，提 供由上至下止回功能；薄弱断裂处受冲击断裂的同时，主封闭板总成A在弹簧A作用下旋转，主封闭板总成A到达图示关闭状态位置，提供由下向上止回功能，保证了双向止回功能。 
本发明有益效果：本装置有用加油领域，可以实现油路双向止回，防止液体倒流。 
为使更进一步了解本发明的特征和技术内容，详见本发明附图和实施方式，然而所附图式仅供参考与说明用，并非是对本发明加以限制。 
【附图说明】
图1为本发明结构图； 
图中，1-主封闭板总成A；2-弹簧A；3-轴；4-打开支架；5-主封闭板总成B；6-弹簧B；7-密封面；8-薄弱断裂处。 
【具体实施方式】
下面结合附图和实施例对本发明做进一步说明： 
如图1所以的一种双向安全止回阀，其腔体内设主封闭板总成B(5)，主封闭板总成B(5)连接有弹簧B(6)，在主封闭板总成B(5)下有一密封面(7)、薄弱断裂处(8)和打开支架(4)，腔体下方轴(3)连接弹簧A(2)和主封闭板总成A(1)。 
当薄弱断裂处受冲击断裂后，打开支架与主封闭板总成B脱离，使主封闭板总成B在弹簧B作用下向下移动，主封闭板总成B移动到关闭状态位置，提供由上至下止回功能；薄弱断裂处受冲击断裂的同时，主封闭板总成A在弹簧A作用下旋转，主封闭板总成A到达图示关闭状态位置，提供由下向上止回功能，保证了双向止回功能。本装置有用加油领域，可以实现油路双向止回，防止液体倒流。 
然而上述仅本发明较佳可行的实施例而已，非因此局限本发明保护范围，依照上述实施例所作各种变形或套用均在此技术方案保护范围之内。
