Description

Water control valve convenient to adjust water level

Technical Field

The utility model relates to an automatic valve of control water level, concretely relates to water control valve convenient to adjust water level.

Background

The automatic water control valve is a valve for automatically controlling the water level of inlet water, the opening and closing of a valve port are controlled through the lifting of a floater, when the water in a container reaches a set water level, the floater enables a valve clack to be automatically closed under the action of buoyancy, when the water in the container is lower than the set water level, the floater sinks downwards under the action of self gravity, the valve clack is opened, the valve is automatically opened, and the water in the container enters the container. 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, a water inlet pipe and a water outlet pipe are respectively arranged on two sides of the valve body, and the water inlet pipe is bent downwards and is communicated with a central pipe. In use, the lower portion of the central tube passes through the bottom of a container (e.g., a toilet tank) and communicates with an external water supply line. The water control valve has the following technical defects: 1. under the common condition, the water inlet pipe and the central pipe are processed into an integral structure, or the water inlet pipe is in threaded connection with the central pipe, the length of the connected water inlet pipe and the central pipe cannot be adjusted, and because the water containers (such as toilet water tanks) have different specifications and types and different internal heights, water control valves of various specifications are required to be processed to be matched with the water containers, and the universality of the water control valves is poor. 2. Some users need to set the water level height of the water container (such as a toilet water tank) according to the condition of using the water container (such as the toilet water tank) so as to achieve the purpose of saving water, and the length of the water inlet pipe after being connected with the central pipe cannot be adjusted, so that the requirements of the users are difficult to meet. 3. There are also lever-type float water control valves on the market, in which the lever and the float are open structures, and although the length of the pull rod on one side of the lever can be adjusted to further adjust the height of the water level, for a water container with a narrow space (such as a toilet water tank), the adjustment of the water level is inconvenient due to the space limitation.

SUMMERY OF THE UTILITY MODEL

In order to overcome current water control valve can not the regulated water level or adjust the inconvenient and poor not enough of commonality of water level, the utility model provides a water control valve convenient to regulated water level adopts piston grafting structure between inlet tube and the center tube in this water control valve convenient to regulated water level to utilize T shape nut to connect, have the characteristics that the regulated water level is convenient, occupation space is little and the commonality is good.

The technical scheme of the utility model is that: the utility model provides a water control valve convenient to adjust water level, includes valve body, float chamber and center tube, and the valve body below is connected with the float chamber of built-in float, and the both sides of valve body are equipped with inlet tube and outlet pipe respectively, be equipped with screw thread section and piston section on inlet tube downwarping and the inlet tube, in the piston section on the inlet tube inserted the center tube from the upper end of center tube, piston section on the inlet tube can reciprocate and seal between piston section and the center tube relatively the center tube, be connected through T shape nut between screw thread section on the inlet tube and the center tube, the main aspects and the center tube threaded connection of T shape nut, screw thread section threaded connection on the tip of T shape nut and the inlet tube, screw thread section on the inlet tube equals with the pitch of the screw.

And an O-shaped ring is arranged on the piston section on the water inlet pipe.

The number of the O-shaped rings is 2.

The thread section and the water inlet pipe main body are welded into a whole through the injection melting joint.

The utility model discloses following beneficial effect has: by adopting the scheme, when the height of the water level is adjusted, the T-shaped nut is rotated to separate the T-shaped nut from the central pipe, then the water inlet pipe is moved up and down to enable the float chamber to reach a proper position, and then the T-shaped nut is connected to the central pipe. The utility model provides an adopt piston grafting structure between inlet tube and the center tube to utilize T shape nut to connect, occupation space is little, and it is convenient to adjust the water level, can adapt to the flourishing water receptacle of various specifications (like toilet tank), and the commonality is good.
