Description

一种微阻止回阀
技术领域
    本实用新型涉及启闭阀门类,具体是一种微阻止回阀。
背景技术
目前,微阻止回阀结构形式各式各样,有启闭式止回阀的形式,也有外置缓冲缸形式,但都就需要一种液体才能够完成阀门关闭时的缓冲,消除破坏性水锤,以保障供水管道设施的运行安全可靠性。但往往由于液压管路的泄漏或阻塞,失去应有的功能。
实用新型内容
本实用新型的目的是提供一种微阻止回阀,安装在管路中或泵的出口处,用于泵停机时防止介质倒流产生水锤冲击泵倒转的安全装置,密封性能稳定可靠,耐磨损、使用寿命长、运行平稳、无振动。
本实用新型的技术方案如下:
一种微阻止回阀,包括有阀体,阀体的两端分别为进水口、出水口,阀体的内腔中转动铰接有横置于阀体内的阀板,阀板外侧的阀体内壁上设有支撑杆,支撑杆外套装有弹簧,所述的阀板的内侧壁上粘接有橡胶缓冲垫,阀体上方的内壁固定有止动块,止动块的顶端顶置于阀板的外侧壁。
    所述的止动块的顶端设有软质垫块。
本实用新型安装在管路中或泵的出口处,用于泵停机时防止介质倒流产生水锤冲击泵倒转的安全装置,具有阀瓣轻开启度大,节电效果显著,流体阻力小,密封性能稳定可靠,耐磨损、使用寿命长、运行平稳、无振动,适用于给排水、消防、暖通等系统管道中或水泵出口处防止介质倒流产生水锤对管路或泵产生危害。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种微阻止回阀,包括有阀体1,阀体1的两端分别为进水口2、出水口3,阀体1的内腔中转动铰接有横置于阀体内的阀板4,阀板4外侧的阀体内壁上设有支撑杆5,支撑杆5外套装有弹簧6,阀板4的内侧壁上粘接有橡胶缓冲垫7,阀体1上方的内壁固定有止动块8,止动块8的顶端顶置于阀板4的外侧壁,止动块的顶端设有软质垫块。
