Description

Water level regulator for water control valve

Technical Field

The invention relates to a device for automatically controlling water level, in particular to a water level regulator for a water control valve.

Background

The automatic water control valve is a valve for automatically controlling the water level in the container, the opening and closing of the water inlet of the valve are controlled through the lifting of the floater, when the water level in the container reaches the set water level, the floater enables the valve clack to be automatically closed under the buoyancy effect, when the water in the container is lower than the set water level, the floater sinks under the self gravity effect, the valve clack is opened, and the valve is automatically opened to allow water in the container to enter. The existing water control valve mainly comprises a valve body, a float chamber and a diaphragm type valve core assembly, wherein the float chamber is connected below the valve body, and a water inlet pipe and a water outlet pipe are respectively arranged on two sides of the valve body. When the water tank is used in some larger water storage tanks, a user cannot adjust the position of the water level in the water tank at any time according to the water consumption of the user, so that excessive water remained in the water tank can be caused, and a fresh water source cannot be timely supplemented.

The device comprises a valve body 1, a float chamber 2, a first float 3, a top pin mounting seat 4, a top pin 5, a spring 6, a flexible rope 7, a second float 8, a connector 9, a spring seat 10, a counterweight 11 and a pull rod 12.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

The water level regulator for the water control valve comprises a valve body 1 and a float chamber 2, wherein the float chamber 2 is positioned below the valve body 1, a first floater 3 capable of controlling the valve clack to be opened and closed is arranged in the float chamber 2, the bottom of the float chamber 2 is connected with a jacking pin mounting seat 4, a jacking pin 5 capable of moving up and down is arranged in the jacking pin mounting seat 4, a spring 6 is arranged between the jacking pin 5 and the jacking pin mounting seat 4, the upper end of the jacking pin 5 is in contact with the bottom of the first floater 3, the lower end of the jacking pin 5 is connected with a second floater 8 through a slender flexible rope 7, a pull rod 12 is arranged at the lower end of the jacking pin 5, and the upper end of the flexible rope 7 is tied in a hole below the pull rod 12. When the second floater 8 does not contact the water surface, the second floater 8 pulls the ejector pin 5 to compress the spring 6, and the first floater 3 controls the valve clack to open; the spring 6 is able to spring the knock pin 5 upwards and push the first float 3 to close the flap when the second float 8 is submerged in water. Due to the adoption of the technical scheme, in a normal state, namely the second floater 8 is not subjected to the buoyancy of water, the ejector pin 5 is pulled downwards under the gravity action of the second floater 8 (comprising a counterweight) to enable the ejector pin 5 to compress the spring 6, at the moment, the first floater 3 sinks under the gravity action of the first floater, the valve clack is opened, the valve is in an open state, and water enters the container; when the water level in the container reaches the height of the second floater 8, the gravity of the second floater 8 is counteracted with the buoyancy of the water, the downward traction force of the ejector pin 5 is lost, the ejector pin 5 is sprung up under the action of the spring 6 and pushes the first floater 3 to enable the valve clack to be closed, the valve is in a closed state, and water inflow in the container is stopped. The invention adds the ejector pin 5, the spring 6 and the second floater 8, the second floater 8 detects the water level height, and the position of the first floater 3 is controlled through the flexible rope 7, the spring 6 and the ejector pin 5, so that the opening and closing of the valve are controlled, and the water level is convenient to adjust by prolonging or shortening the length of the flexible rope 7 when the water level height is adjusted, thereby meeting the requirements of users.

The lower end of the float chamber 2 is provided with a joint 9, and the ejector pin mounting seat 4 is in threaded connection with the joint 9. The ejector pin mounting seat 4 is of an integrated structure, is in threaded connection with the joint 9, and is convenient to assemble.

The spring seat 10 is arranged in the ejector pin mounting seat 4, the spring 6 is sleeved outside the ejector pin 5, and the lower end of the spring 6 is arranged in the spring seat 10. The spring seat 10 plays a role in positioning, and can stabilize the spring 6 and prevent the spring 6 from being inclined.

The second floater 8 is connected with a counterweight 11. The pulling force of the second floater 8 on the jacking pin 5 is conveniently adjusted through the counterweight 11 so as to overcome the elastic force of the spring 6.

The above-mentioned embodiments should not be construed as limiting the invention, and any float-type water control valve of any configuration may be used with the modifications of the invention, and any product that is the same as the spirit and substance of the invention should be construed as being within the scope of the invention.
