Description

一种微阻缓闭止回阀
技术领域
    本实用新型涉及启闭阀门类，具体是一种微阻缓闭止回阀。
背景技术
目前，微阻缓闭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缓闭止回阀，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：
一种微阻缓闭止回阀，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，阀体的下端为支撑台，支撑台内设有导向孔，导向孔内滑动安装有阻力杆，阻力杆外套装有弹簧，所述的阀杆的外侧壁上粘接有橡胶缓冲垫。
    所述的阀体的顶端安装有压力表。
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，一种微阻缓闭止回阀，包括有阀体1，阀体1的两端分别为进水口2、出水口3，阀体的内腔中转动铰接有横置于阀体内的阀板4，阀体的下端为支撑台5，支撑台5内设有导向孔6，导向孔6内滑动安装有阻力杆7，阻力杆7外套装有弹簧8，阀杆的外侧壁上粘接有橡胶缓冲垫9，阀体的顶端安装有压力表10。
