Description

螺纹连接球式止回阀
技术领域:本实用新型属于止回阀,适用于工业、民用蒸汽锅炉及锅炉辅助给水设备系统,特别涉及一种螺纹连接球式止回阀。
背景技术:目前止回阀密封不严,易磨损,易粘卡,易造成介质倒流现象,使用寿命短。
发明内容:本实用新型的发明目的是根据上述问题提供了一种螺纹连接球式止回阀,这种止回阀,入口阀座,阀腔内有阀球(4)、阀球(4)与阀腔空隙大,可解决密封不严、易磨损、易粘卡、易造成介质倒流现象和使用寿命短等问题。
本实用新型是这样实现的(如图):一种螺纹连接球式止回阀,由阀体(1)、出口阀座(2)、检查丝堵(3)、阀球(4)和入口阀座(5)组成,出口阀座(2)和入口阀座(5)与阀体(1)为一体,入口阀座(5)为锥形,阀腔内有阀球(4),阀体(1)两端内有螺纹。
本实用新型的加工简单,安全可靠,密封性能好,维修方便,使用寿命长。
附图说明:附图为螺纹连接球式止回阀剖面图。
具体实施方式:首先按图要求做模具,铸造成型后,将阀球(4)装入阀腔,上紧检查丝堵试压,用车床车阀体(1)两端内螺纹,试压检测。
