Problems solved by technology

However, no matter whether it is a pull-type spool or a push-type spool, there are the following disadvantages: the sealing structure of the control rod directly blocks the water inlet of the valve casing, resulting in a large water pressure, and manual operation and control When using the control rod, it needs a lot of strength; when it uses elastic parts for the control rod to reset itself, the elastic parts also need to overcome the water pressure, which makes the elastic parts prone to fatigue and affects the service life

Embodiment Construction

[0026] Examples, see Figure 1-Figure 4 As shown, a valve core of the present invention includes a valve housing 1 with a transparent structure at both ends, a control rod 2, a hydraulic control member 3, a waterway control seal 6 and a capillary pore forming member 5; the hydraulic control member 3 A water pressure chamber 33 with a first opening 31 and a second opening 32 is formed. The side of the valve housing 1 is provided with a secondary water outlet hole 12 and a main water outlet hole 11, one end of which is a water inlet 13; the water pressure control part 3 and the waterway control seal Parts 6 are respectively set in the valve casing 1, and the waterway control sealing part 6 forms a seal on the second opening 32 of the water pressure control part 3. The waterway control sealing part 6 has the function of being affected by the water pressure difference and can be elastically deformed to communicate with the valve. The water inlet end 13 of the shell 1 and the defor...

Abstract

The invention discloses a valve element and a water way control valve. The valve element comprises a valve shell, a control rod, a water pressure control piece, a water way control sealing piece and a capillary hole forming element. The water pressure control piece forms a water pressure cavity with a first opening and a second opening. An auxiliary water outlet and a main water outlet are formed in the side face of the valve shell, wherein one end is a water inlet end. The water pressure control piece and the water way control sealing piece are arranged in the valve shell in a sleeved mode. The water way control sealing piece is provided with a deforming part which is directly or indirectly matched with the main water outlet of the valve shell in a sealing mode. The capillary hole forming element is arranged on the water way control sealing piece in a sleeved mode, and a capillary hole for being communicated with the water pressure cavity and the water inlet end of the valve shell is formed. The first opening of the water pressure cavity is communicated with the auxiliary water outlet of the valve shell. The control rod is movably arranged the water pressure control piece in a sleeved mode and is provided with a sealing part. The first opening is opened or sealed by the fact that the sealing part moves in the axial direction along with the control rod. The water way control valve comprises a valve body and the valve element. The water way control valve has the advantages that operation force is small, and operation stroke is short.

Description

technical field [0001] The invention relates to a valve core, in particular to a valve core and a waterway control valve with labor-saving operation and short operation stroke. Background technique [0002] The spools of the prior art can be mainly divided into three categories according to their operating modes: rotary spools, pull-type spools and push-type spools, wherein the pull-type spools and the push-type spools are similar, and both adopt The control rod that can move axially realizes the opening or closing of the waterway. Specifically, a blocking structure is set on the control rod. By moving axially, the blocking structure blocks or leaves the water inlet hole of the valve housing, so as to achieve the switch purpose of water. However, no matter whether it is a pull-type spool or a push-type spool, there are the following disadvantages: the sealing structure of the control rod directly blocks the water inlet of the valve casing, resulting in a large water pressur...
