Pressure sealing structure and water heating valve with automatic opening and closing function

Abstract

The invention relates to the technical field of valves, in particular to a pressure sealing structure and a water heating valve with an automatic opening and closing function. The water heating valvecomprise a valve body, a driving mechanism arranged above the valve body and a sealing mechanism arranged at the inner side of the valve body, wherein the valve body comprises an upper valve body anda lower valve body; water inlets and water outlets are arranged in the two ends of the upper valve body; a sealing part is arranged at the top of the lower valve body; a circulation opening allowing water flow to pass through is arranged in the bottom of the sealing part; a limiting part is arranged at the inner side of the circulation opening; a valve plate capable of moving vertically is inserted into the limiting part; and the top end of the valve plate penetrates above the circulation opening. The valve body is formed by connecting the upper valve body and the lower valve body in the threaded mode, so that the upper valve body and the lower valve body can be detached during maintenance, a sealing structure in the valve body is convenient to replace, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a water heating valve with a pressure sealing structure and an automatic opening and closing function. Background technique [0002] Plumbing is one of the types of radiant floor heating, and it is also the most popular heating method at present. The water heating is through the ground coil, the circulating hot water in the pipe, through the heat medium in the radiant layer of the floor, evenly heats the whole ground, and uses the ground's own heat storage and the law of heat radiation upward to conduct from bottom to top to achieve The purpose of heating. Since the temperature gradient gradually decreases from the bottom of the feet to the head is formed indoors, it gives people a comfortable feeling of warming the feet and cooling the head. [0003] The water heating coil is a hose evenly distributed under the ground, and its two ends are connected to the water tank. The water...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing plumbing valve has an integral structure, and the valve body cannot be disassembled. When the sealing structure inside the valve is worn, it cannot be replaced in a targeted manner. Therefore, the entire valve can only be replaced, so the maintenance cost is high;

[0005] 2. Most of the existing plumbing valves are composed of a valve body and an internal valve plate. When the water heating is turned off, the valve plate will bear huge water pressure. As the use time increases, the valve plate will easily deform and cause the valve to be sealed. decreased sex
