Simple hydration control ball valve mechanism

The invention relates to a hydration control ball valve mechanism, in particular to a simple hydration control ball valve mechanism applied to a water replenishing tank which can automatically replenish water and automatically close when reaching a predetermined liquid level.

The traditional hydration control ball valve mechanism mainly connects the inlet end of the valve body of the ball valve to the water source, the water outlet end is located at the bottom of the valve body, and a rod is arranged on the valve body, and one end of the struts is connected to the valve body. The ball plug, the other end of the pole is connected with a float ball, and the float ball drives the ball plug valve switch with the rise and fall of the water level.

At present, there is a hydration control float ball valve mechanism disclosed in the new patent case of the water meter of the water tower float ball valve No. M361587, wherein the float ball valve is provided with a piston in the valve body thereof, and the piston is connected with a rod. Extending out of the valve body, and then connecting a floating ball, the water level device is mainly connected to an arm plate on a bracket, and then connected to a floating ball by a soft cable on the arm plate, the water level device can be disposed on the floating ball valve. The outer side of the valve body is sleeved on the floating ball struts of the floating ball valve by the arm plate, or the water level device can also set the bracket and the arm plate inside the valve body, and the side end of the arm plate is a guiding portion having a hook portion, the soft portion of the floating ball is connected by the guiding portion, and the piston of the floating ball valve body is hooked by the hook portion, thereby controlling the floating by the weight of the floating and sinking ball through the soft cable The ball valve bleeds the influent water level of the fluid and opens the float valve into the water at a low water level.

Although the water level device can utilize the gravity and buoyancy action of the float ball and the floating sun ball to achieve the control function of the water tank automatic water supply, if the ball plug valve is connected to the pressurized water source, the ball plug in the ball plug valve is pressurized. The resistance of the fluid is not easy to switch normally. Or, after the ball valve is used for a period of time, the fouling in the valve body will cause a clamping effect on the piston in the ball valve, causing the ball valve to fail to switch normally, resulting in the water level. The combination of the valve and the ball valve is not suitable for automatic pressure control of large pressure fluids.

In addition, the above-mentioned conventional water level device does not have an adjustment function, and it is difficult to change the torque required for the ball valve switch, and it is also impossible to change the maximum switching angle of the ball valve.

At this time, the force of the weight hang 22 is also applied to the control rod 21 to increase the torque of the open ball valve 10, so that the ball valve 10 can maintain the normal switch. .

In the foregoing, the present invention changes the position of the weight hanging 22 to the axis of the ball valve 10 by adjusting the position of the weight hanging 22 on the control rod 21, as shown in FIG. 7 and FIG. If the distance is long, the torque of the opening ball valve 10 can be increased, and the distance of the floating ball 31 to the axis of the ball valve 10 can be changed by using the adjustable length of the control rod 21, and the distance can be increased to increase the closing ball. The torque of the plug valve 10.

In addition, as shown in FIG. 7 and FIG. 8, the present invention can also adjust the angle limit of the downward rotation of the control lever 21 by the adjusting bolt 42 of the angle adjusting device 40, and can adjust the maximum switching angle of the ball valve 10. In another aspect, the present invention can be utilized with the adjustable float connection assembly 32 of the float device 30 to vary the level of the hydration control by adjusting the overall length of the float connection assembly 32 that connects the floats, wherein the float is utilized. The elongation of the connecting component 32 can reduce the liquid level of the water replenishing control. Conversely, shortening the length of the floating ball connecting component 32 can increase the liquid level of the hydration control.
