Description

Technical Field

[0001] The utility model relates to the technical field of valve bodies, in particular to a self-cleaning time-delay urinal valve. Background Art

[0002] In plumbing products, the urinal valve is a valve installed on the container, and its main function is to control the water flow. The working principle of the urinal valve is very simple. The valve cuts off the water flow and opens the sluice gate, and then uses the water flow pressure to flush the container. Due to factors such as frequent use of the valve or poor water quality, the inside of the urinal valve may be blocked. The existing technology mostly uses the valve body to disassemble for cleaning, which is inconvenient.

[0003] Based on this, the inventor studied and proposed this case. Utility Model Content

[0004] The utility model provides a self-cleaning time-delay urinal valve, which overcomes the shortcomings described in the background technology.

[0005] The technical solution adopted by the utility model to solve its technical problem is:

[0006] A self-cleaning delayed urination valve comprises a valve body, a button self-cleaning valve core group, an inlet pipe group and an outlet pipe group. The valve body is nested with a button self-cleaning valve core group, the inlet pipe group is connected with the interior of the valve body, and the button self-cleaning valve core group is opened by controlling the button self-cleaning valve core group, so that water in the inlet pipe group passes through the button self-cleaning valve core group and flows to the outlet pipe group. The outlet pipe group is connected with the interior of the valve body. The button self-cleaning valve core group comprises a button, a reset spring, a push rod group, a basic valve core, a seat body and a self-cleaning spring. The basic valve core is penetrated with a push rod group, the button is nested at one end of the basic valve core, and a reset spring is installed between the button and the basic valve core. The seat body is nested in the valve body, and one end of the push rod group is slidably installed on the inner surface of the seat body. The side end of the push rod group and the inner surface of the seat body form a chamber, a self-cleaning spring is arranged in the chamber, a perforation is arranged on the side of the chamber in contact with the self-cleaning spring, a compressibly displaced straight section structure is arranged on the self-cleaning spring, and the straight section structure is matched along the displacement of the perforation. The straight section structure is specifically achieved by reserving a sufficient length on one side of the self-cleaning spring in contact with the push rod group, and then bending it to first pass through the inside of the self-cleaning spring and then pass through the chamber.

[0007] The self-cleaning delayed urinal valve of the utility model relies on the time difference between the time required for the reset spring and the self-cleaning spring to recover after being deformed by force; the self-cleaning is achieved by the cooperation between the straight section structure of the self-cleaning spring in the valve body and the perforation on the chamber.

[0008] A preferred technical solution: A water outlet cavity is provided on the side where the valve body is connected to the water outlet pipe assembly, and the input end of the water outlet cavity opens or closes the internal water passage of the basic valve core through the cooperation of the basic valve core and the push rod assembly. The input end of the water outlet cavity refers to the end where water enters the water outlet cavity after passing through the basic valve core when the valve body is opened.

[0009] A preferred technical solution: a water inlet cavity is provided on one side of the valve body connected to the water inlet pipe assembly, and a mounting port is provided on one side of the water inlet cavity of the valve body.

[0010] A preferred technical solution: a decorative sheet is arranged on the outer side of the installation opening.

[0011] A preferred technical solution: A sealing ring is provided at the nested installation position of the basic valve core and the valve body.

[0012] A preferred technical solution: a sealing ring is provided at the nested installation position of the seat body and the valve body.

[0013] A preferred technical solution: a cone seat is arranged on one side of the open end of the seat body, a flow port is arranged on the cone seat, and a blocking structure adapted to the flow port is arranged on the push rod assembly.

[0014] A preferred technical solution: the installation port is a built-in screw port.

[0015] A preferred technical solution: an external threaded port is provided on one side of the water outlet cavity of the valve body.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are:

[0017] The utility model drives the self-cleaning spring through the push rod group, and the self-cleaning spring is compressed while one end of the spring straight section structure passes through the small hole of the chamber; if debris passes through, the movement of the self-cleaning spring and the cooperation of the water flow, the foreign matter is automatically cleaned by the flow of water pressure, and the self-cleaning effect is achieved. The overall structure is simple and the promotion and application value is high. BRIEF DESCRIPTION OF THE DRAWINGS
