Problems solved by technology

[0004] But above-mentioned pressing mechanical automatic switch spool drives the telescopic movement spring action in the water sealing seat through the magnetic attraction force of telescopic auxiliary magnet through the constriction portion on the water sealing seat, after long-term use, the magnetic attraction force of magnet will weaken and The spring of the telescopic movement is soaked in water, and the magnetic attraction force it receives is easily affected. Therefore, the stability of the push mechanical automatic switch valve core is poor during use.

Embodiment 1

[0028] Such as figure 1 and figure 2 As shown, the push-type spool includes a spool shell 1, a spool 2 arranged in the spool shell 1, an elastic member 3, a rotating sleeve 4 arranged on the top of the spool shell 1, and the rotating sleeve 4 can be positioned at a high position and The telescopic mechanism 5 for switching between low positions has a water outlet hole 1a at the bottom of the valve core housing 1, and a water inlet hole 1b at the side of the valve core housing 1. The spool 2 moves up under the action of the elastic member 3 and makes the upper end of the spool 2 abut against the lower end of the rotating sleeve 4. The lower end of the spool 2 has a sealing portion, which can extend when the rotating sleeve 4 moves to a lower position. Into the water outlet hole 1a and block the water outlet hole 1a.

[0029] Specifically, the valve core housing 1 includes a cylindrical housing 1c and a valve seat 1d fixed on the bottom of the housing 1c. Several clamping ho...

Embodiment 2

[0036] The structure and working principle of the push-type spool in this embodiment are roughly the same as those in Embodiment 1, the difference is that there is an abutment piece made of rigid material between the upper end of the spool 2 and the lower end of the rotating sleeve 4, which abuts against The upper side of the piece abuts against the lower end of the rotating sleeve 4, and the lower side of the abutting piece abuts against the upper end of the spool 2.

[0037] In this embodiment, the abutting member includes a ball 6, the lower end of the rotating sleeve 4 is provided with a concave friction groove 4a, and the upper end of the valve core 2 is provided with a concave friction groove 2b at a position corresponding to the friction groove 1 4a. The diameter of the ball 6 is greater than the depth of the first friction groove 4a and the diameter of the ball 6 is greater than the depth of the second friction groove 2b, and the ball 6 partly extends into the first fri...

Embodiment 3

[0039] The structure and working principle of the push-type spool in this embodiment are roughly the same as those in Embodiment 2, the difference is that the abutment includes connector one 7 and connector two 8, both of which are made of ceramic materials, connector one 7 It is fixedly connected with the lower end of the rotating sleeve 4, and the second connecting piece 8 is fixedly connected with the upper end of the valve core 2. The opposite sides of the first connecting piece 7 and the second connecting piece 8 are planes and the two are adjacent to each other. Here, the friction coefficient of the ceramic material is small and the wear resistance is good, and the force and push between the valve core 2 and the rotating sleeve 4 are more stable through the plane abutment between the first connecting piece 7 and the second connecting piece 8 .

Abstract

The invention provides a press type valve element and belongs to the technical field of valves. The press type valve element solves the problem that an existing press type valve element is poor in use stability. The press type valve element comprises a valve element shell, a valve element body, an elastic piece, a rotating sleeve and an extending and retracting mechanism, wherein the valve element body and the elastic piece are arranged in the valve element shell, the rotating sleeve is arranged on the upper portion of the valve element shell, and the extending and retracting mechanism enables the rotating sleeve to be switched between a high position and a lower position. The bottom of the valve element shell is provided with a water outlet hole. The valve element body can be far away from the water outlet hole and acts on the lower end of the rotating sleeve under the action of elastic force of the elastic piece. The upper end of the valve element body abuts against the lower end of the rotating sleeve, or an abutting piece is arranged between the upper end of the valve element body and the lower end of the rotating sleeve, and the upper side and the lower side of the abutting piece abut against the rotating sleeve and the valve element correspondingly. The lower end of the valve element body is provided with a seal portion. The seal portion can extend into the water outlet hole and block the water outlet hole when the rotating sleeve moves to the lower position. The press type valve element has the advantage of being good in use stability.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a valve core, in particular to a push type valve core. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief, etc., and are widely used in various fields. At present, the commonly used valves are generally rotary control valves, that is, the switch control of the valve needs to be driven by turning the handwheel or handle. situation, it is more inconvenient to use. [0003] For this reason, people have designed a kind of pressing mechanical automatic switch spool, and have applied for Chinese patent (its application number is: 201620370370.9; Its announcement number is: CN205715926U), this spool includes upper valve body and lower valve body, upper valve There is a water sealing seat betwe...
