Description
技术领域technical field
本实用新型属于流体控制技术领域,具体涉及一种浮球阀。The utility model belongs to the technical field of fluid control, in particular to a floating ball valve.
背景技术Background technique
现有常见的浮球阀由曲臂和浮球等部件组成,可用来自动控制水塔或水池的进水,从而控制液面。The existing common float valve is composed of a crank arm and a float ball and other components, which can be used to automatically control the water inlet of a water tower or a pool, thereby controlling the liquid level.
浮球阀的工作原理为:浮球始终都要漂在液面上,当液面上涨时,浮球也跟着上升。浮球上升一并带动连杆也上升。连杆与另一端的阀门相连,当上升到一定位置时,连杆支起橡胶活塞垫,封闭水源。当水位下降时,浮球也随液面下降,连杆又带动活塞垫开启水源。当进水水源压力比较高时,要通过浮球的上升带动连杆从而再带动活塞垫关闭进水水源。由于活塞受到的进水压力为轴向力,这种情况下就需要足够的驱动力,这个驱动力只能通过增大浮球体积从而增大浮力,使连杆带动的活塞获得足够大的作用力从而关闭进水。或者在浮球体积不改变的情况下,增加连杆长度,通过增大力矩来带动活塞关闭进水。但无论是增大浮球体积还是增加连杆长度,由于其使用场合受空间限制,不能提供足够的空间来安装布置大体积浮球、长连杆的浮球阀,因此只能使用成本更高的液位控制方式。The working principle of the floating ball valve is: the floating ball must always float on the liquid surface, and when the liquid level rises, the floating ball also rises. When the floating ball rises, the connecting rod also rises. The connecting rod is connected with the valve at the other end. When it rises to a certain position, the connecting rod supports the rubber piston pad to close the water source. When the water level drops, the float ball also drops with the liquid level, and the connecting rod drives the piston pad to open the water source. When the pressure of the inlet water source is relatively high, the connecting rod is driven by the rise of the floating ball, thereby driving the piston pad to close the inlet water source. Since the water inlet pressure on the piston is an axial force, sufficient driving force is required in this case. This driving force can only increase the buoyancy by increasing the volume of the floating ball, so that the piston driven by the connecting rod can obtain a sufficiently large effect. force to close the water inlet. Or in the case that the volume of the floating ball does not change, increase the length of the connecting rod, and drive the piston to close the water inlet by increasing the torque. However, whether it is to increase the volume of the floating ball or increase the length of the connecting rod, due to the space limitation of its use, it cannot provide enough space to install the floating ball valve with large volume floating ball and long connecting rod. Liquid level control method.

所述阀内筒13为一个圆筒,圆筒下端侧面开若干个孔,孔的数量及尺寸可调。The valve inner cylinder 13 is a cylinder, and a plurality of holes are opened on the side of the lower end of the cylinder, and the number and size of the holes are adjustable.
所述阀座16底部为一个带有液体流出管口的圆柱状筒体,液体从阀外筒01管口进入后,当阀芯04处在高位时,则阀内筒13下端侧面孔为开启状态,液体进入阀内筒13后从阀座16下端的管口流出。The bottom of the
所述的一种浮球阀,液体经过阀外筒01进入内部后,由于此时浮球07处于低位状态,连杆06通过销轴05的连接使阀芯04处于高位状态,所以阀内筒13下端侧面的孔为开启状态,液体流经阀内筒13后从阀座16下端筒体管口流出进入容器。当容器内液位升高时,浮球07也随之升高,阀芯04在连杆06带动下下滑到低位状态,阀内筒13处于关闭状态,液体停止流动及进入。阀内筒13、阀外筒01与阀盖02、阀座16之间的密封垫,通过螺杆03把它们加紧固定,防止渗漏。阀芯04上面安装两个密封圈17可以使阀芯04在低位时阀门关闭更严密。In the above-mentioned floating ball valve, after the liquid enters the interior through the valve

2)本实用新型中,由于阀芯和阀内筒的开启或关闭由现有技术中的油流轴向推动阀芯的作用力优化为剪切作用力,无论进入浮球阀的液体其压力大小,该浮球阀均适用,所以对于浮球大小与连杆长度的选择只需满足浮球上下摆动的驱动力能够克服阀芯上下活动的摩擦力与自身重力即可。2) In this utility model, due to the opening or closing of the valve core and the valve inner cylinder, the force of the oil flow in the prior art to push the valve core axially is optimized as a shear force, regardless of the pressure of the liquid entering the float valve. , the floating ball valve is applicable, so the selection of the size of the floating ball and the length of the connecting rod only needs to satisfy the driving force of the floating ball swinging up and down to overcome the friction force of the valve core moving up and down and its own gravity.
