The utility model relates to a hydraulic water level control valve. Including the valve body and the valve cover, the valve three is provided with a throttle body cavity, the central nut and the valve stem in the stem at the bottom of the filter is provided with a central stem, and the bottom is provided with a through hole; the diaphragm is arranged between the body cavity and the adjacent cavity; the valve pad is arranged between the side cavity and the inferior vena cava, between the valve flap and pad the inferior vena cava is provided with a guide with three claw gland, between the valve guide pad, gland and stem through the guide nut fixed. The utility model has the advantages of hydraulic level control valve designed by using the principle of control, novel structure, scientific and reasonable, simple and easy; the working state is stable and reliable, flexible and open in the use of pressure within the prescribed scope of water hammer impact; raw material saving, light weight, small volume, low cost, and convenient installation and maintenance.
【技术实现步骤摘要】
本技术为一种水位控制阀,特别是一种液压水位控制阀,主要用于工矿企业和民用建筑的水箱、水池和水塔等储水器,用来自动控制水位。即当储水器中的水位低于规定位置时自动启阀让水进入,当水位达到规定位置时自动闭阀和停止进水。现有技术为浮球阀见图3,连接有阀杆26的横杆27外端有浮球28,阀体29装于储水器内,阀体旁的法兰盘30与进水管道连通。当储水器内水位下降时,浮球牵动横杆下降,阀31开启,水从旁口进入并向下注入储水器。待水位达到规定位置时,浮球通过横杆带动阀杆和阀上升,直至阀关闭,停止向储水器注水。其不足之处在于浮球大,整体结构较笨重;由于阀装于储水器内,安装和维修不方便。本技术的目的在于克服上述现有技术中的不足之处而提供一种装于储水器外、采用液压闭阀、结构轻巧、安装维修方便的液压水位控制阀。本技术设计的液压水位控制阀包括阀体和阀盖,所述阀盖内表面上有三个位置控制爪;所述阀体为三通腔体,阀体中央设有节流螺母和阀杆,阀杆中央自上而下设有一通孔;在阀体上腔和旁腔之间设有膜片,在上腔与膜片之间设有上压盖,在旁腔与膜片之间设有阀瓣,所述上压盖、膜片和阀瓣之间由连接螺栓固定;在旁腔与下腔之间设有阀瓣垫,在阀瓣垫与下腔之间设有带有三个爪的导向压盖,所述阀瓣垫、导向压盖与阀杆之间通过导向螺母固定。本技术设计的液压水位控制阀还可以包括阀杆下端设有的过滤器。本技术设计的液压水位控制阀运用运用原理控制,结构新颖,科学合理,简单易行;工作状态平稳可靠,在规定的使用压力范围内开启灵活,无水锤冲击;节省原材料,重量轻、体积小,成本低,且安装维修方便。下面结合实施例和附图对本技术作进一 ...
