Abstract

The utility model relates to a liquid full self controller, which comprises a floating ball groove and a floating ball rising and falling in the groove. The floating ball groove is connected with a water outlet pipe of tap water through a water inlet pipe extending downwards and is connected with an overflow pipe and an inlet pipe of a container through a bypass. The pipe of the lower end of a pipe body is provided with a self controlling valve seat and a valve core, and the floating ball is connected with the valve core through a hard lever, the lower end of which is provided with a fork lever. By using the utility model, users do not need to watch and wait that the solar water heater is full of water to close the valve when a solar water heater is filled with water, and a self controlling valve can be automatically closed to stop filling water in the container when the container is full of water through the function of the floating ball.

Description

The hydroful automatic controller

The utility model relates to a kind of full liquid automatic controller, is used for high-level container, particularly the automatic control of the water inlet of solar water heater.

Some high-level container, for example be contained in the solar water heater on roof, owing to can't observe the liquid level in the container, water intaking valve generally need be waited until in the run-down pipe there are flowing out after opening, when water has been filled it up with in the expression container, just water valve cuts out, in this process, need long waiting time, the people can not leave, and is cumbersome.

The purpose of this utility model provides a kind of full liquid automatic controller, and it is used for high-level container, and especially for solar water heater, automatic stop water inlet in the time of making into water to certain liquid level avoids waiting for that hydroful closes the trouble of valve.

This hydroful automatic controller comprises a ball float groove and ball float that can lifting in groove, the ball float groove can link to each other with the rising pipe of tap water by the water inlet pipe that extends downwards, this water inlet pipe is provided with the bypass that can be connected with container run-down pipe and container induction pipe respectively, be provided with automatic control valve seat and spool in the pipe of body lower end, ball float links to each other with spool by the stiff rod that a lower end is provided with fork arm, the automatic control valve seat is provided with a pair of pilot hole, and fork arm passes two pilot holes and links to each other with the automatic control spool.

This hydroful automatic controller is used for solar water heater or other high-level container, when water valve is opened water inlet, water level rises in the container, when water level rises to when being higher than run-down pipe, water inlet in the ball float groove, when ball float was upwards floated by buoyancy, internally piloted valve was raised and makes and close automatically, and the water inlet pipe stop is intake to container.Therefore, from will be behind the tap water opening of valves can relieved leaving away, need not to wait for and wait for and close valve, make the water inlet operation of solar water heater easier, more reliable.

Below in conjunction with description of drawings structure of the present utility model.

Fig. 1 is the structural representation of the utility model hydroful automatic controller.

Fig. 2 is valve seat construction figure.

As shown in Figure 1, the upper end of water inlet pipe 5 is provided with ball float groove 1, ball float 2 is arranged in the ball float groove, the bypass 3 of water inlet pipe is joined with the run-down pipe of solar water heater, the induction pipe of bypass 6 and solar water heater joins, ball float 2 is connected with stiff rod 4, the lower end fork arm 7 of stiff rod is connected with automatic control spool 8, the lower end pipe internal fixation of water inlet pipe has valve seat 9, fork arm passes a pair of pilot hole 9-1 of valve seat, and can move up and down in the hole, and the structure of valve seat is seen Fig. 2, it is an annular solid, and pilot hole 9-1 is located on the cross bar 9-2 of annular solid.

Claims

The hydroful automatic controller, comprise a ball float groove and ball float that can lifting in groove, it is characterized in that the ball float groove links to each other with the rising pipe of tap water by the water inlet pipe that extends downwards, this water inlet pipe is provided with the bypass that can be connected with the run-down pipe and the induction pipe of container respectively, be provided with automatic control valve seat and spool in the pipe of water inlet pipe lower end, ball float links to each other with spool by the stiff rod that a lower end is provided with fork arm, and the automatic control valve seat is provided with a pair of pilot hole, and fork arm passes two pilot holes and links to each other with the automatic control spool.
