Embodiment Construction

[0012] It can be seen from the drawings that the automatic descaling delay valve includes a valve body 1, a valve core assembly 2 fixed in the valve body and a valve cover 3 connected to the valve body 1, wherein the valve body is provided with an open inner cavity, and the inner cavity The wall is provided with threads 4 for connecting the "convex" shaped gland 15, the fastening ring 23 and the valve cover 3. A sealing platform 5 is provided at the bottom of the inner chamber, and a water inlet hole 7 in the center of the inner chamber communicated with the water inlet connection interface 6 is arranged in the center. The water inlet hole 7 is provided with a sealing boss 8 along the edge, so as to make the structure of the valve body 1 more compact and the shape more compact. Aesthetically pleasing, the shape of the valve body 1 is in the shape of a "turtle body" or "round cake", and the inlet and outlet water connection interfaces 6, 26 are arranged on the center line of the...

Abstract

A delay valve able to automatically remove the water scale is composed of valve body, valve core module and valve cover. It features that its flexible damping valve core consisting of two half-open dampers and spring is combined with the steel needle and big and small sealing membranes to form a multi-sealing scheme, realizing the float, flexible and delayed water discharge, automatically controlled sealing, and automatically removing water scale.

Description

technical field [0001] The invention relates to a valve, in particular to an automatic descaling delay valve. Background technique [0002] There are many types of valves that combine damping and valve needles to form a damping spool system to reduce the occurrence of clogging, such as elimination devices for reducing vibration, injection valves for fuel delivery, and electromagnetic hydraulic valves for controlling hydraulic systems. , Delay valve for flushing, etc. Especially for the delay valve for direct flushing, there is also a damping valve needle structure to reduce the blockage of the damping hole by scale and cause poor water supply. In this type of structure, the traditional long pull rod is mostly used as the starting rod to achieve the purpose of labor-saving operation and easy maintenance. But this type of structure is not suitable for horizontal structure and can only be used as vertical structure, so the scope of use is limited, such as the tie rod structur...
