Valve element of small-sized bottom-inlet side-outlet magnetic time delay valve

Abstract

The invention relates to a switch valve product, in particular to a valve element of a small-sized bottom-inlet side-outlet magnetic time delay valve. The valve element of the small-sized bottom-inlet side-outlet magnetic time delay valve comprises a valve body, wherein a magnetic valve structure is arranged at the upper part of the valve body; the middle part of the valve body adopts a cylinder body structure; a water storage cavity is formed inside the cylinder body; a time delay water hole communicated with a water inlet cavity and a water storage cavity is also formed inside the cylinder body; a sliding push rod is arranged inside the magnetic valve; a magnetic post is installed at the top of the sliding push rod; a return spring is installed between the top of a piston and the bottom of the magnetic valve; the valve element of the small-sized bottom-inlet side-outlet magnetic time delay valve has structural key points as follows: a bottom plate is arranged at the lower part of the valve body; the inlet of a water inlet passage is formed in the bottom plate of the valve body; a water outlet passage, of which a water outlet is formed in the peripheral side wall of the valve body is formed above the bottom plate; the water inlet cavity is formed in the middle of the valve body; a pressure relief cavity is formed in the periphery of the valve body; a rubber sealing ring is installed on a sealing head at the lower end of the piston to form lower limiting seal with the bottom plate. The valve element of the small-sized bottom-inlet side-outlet magnetic time delay valve is small in size, higher in adaptability, simple in structure, material-saving and water-saving.

Description

technical field [0001] The invention relates to a switch valve product, in particular to a small bottom-in and side-out magnetic time-delay valve core. [0002] Background technique [0003] Patent No. 2013203371659 discloses a bottom-in and side-out magnetic delay flush valve spool. like figure 1 As shown, there is a valve body 10, the upper part of the valve body 10 is provided with a magnetic valve structure, and the middle part of the valve body 10 is a cylinder structure, especially: the lower part of the valve body 10 is provided with a bottom plate 12 and an axial arc partition 28 is divided into the water inlet 11 and the water outlet 13, the inlet of the water inlet 11 is opened on the bottom plate 12 of the valve body 10, the outlet of the water outlet 13 is opened on the side wall of the valve body 10, and the inlet end of the water outlet 13 is a retaining ring Structure 27; a piston is housed in the cylinder, and the piston is composed of a head 20, a rod ...

AI Technical Summary

Problems solved by technology

[0004] The spool of the bottom-in and side-out magnetic force delay flushing valve is formed by separating the water inlet 11 and the water outlet 13 at the bottom of the valve body by an arc-shaped partition 28 arranged on the bottom plate 12, and the height of the arc-shaped partition affects the The overall height of the valve body makes the valve body high in height and large in volume, which is only suitable for installation on larger faucets and urinal flush valves. It cannot be installed on faucets with smaller designs. The valve core is suitable for sexually restricted
