Problems solved by technology

However, due to the cooperation between the valve core and the valve body of the manual three-way water diversion valve, the outer wall of the valve core and the inner wall of the valve body are used to achieve the sealing effect, due to errors in manufacturing or assembly, or due to long After a long time of use, a gap will easily appear between the valve core and the valve body after wear and tear, making the sealing effect of the manual three-way water diversion valve poor

Embodiment 1

[0030] Such as Figures 1 to 4 As shown, a seal for a steering valve. The steering valve includes a valve body 1, a valve core 2, and a valve stem 3. The valve core 2 is cylindrical. The valve body 1 is provided with a water inlet 1a and a water outlet 1b. The valve core A valve core hole 2a is opened on the side of the valve core 2, and the sealing member is arranged between the outer wall of the valve core 2 and the inner wall of the valve body 1. The sealing member includes a ring-shaped support seat 5 positioned with the valve body 1 And the sealing part 4 fixed to the support seat 5, the sealing part 4 is annular and its outer side is two parallel and annular protruding sealing lips 4a, each sealing lip 4a is attached to the outer wall of the valve core 2 superior. The sealing lips 4a each include two strip-shaped force-receiving parts 4a1 parallel to the axis of the valve core 2, and the corresponding two ends of the force-receiving parts 4a1 are connected by an arc-sha...

Embodiment 2

[0035]The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: Figure 5 As shown, the inner side of the sealing part 4 is a plurality of strip-shaped fixing parts 4b. The fixing part 4b is embedded in the support seat 5 and one end thereof is connected to the inner side of the sealing lip 4a. The fixed part 4b is embedded in the support seat 5 to make the seal The part 4 is fixedly connected with the supporting seat 5, which has the advantages of simple structure and convenient connection.

Embodiment 3

[0037] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: Image 6 As shown, the sealing part 4 and the supporting seat 5 are integrally cast with rubber, and the sealing part 4 and the supporting seat 5 are integrally cast with rubber, which has the advantages of simple process and convenient manufacture.

Abstract

The invention provides a seal for a reversing valve, which belongs to the technical field of valves. The invention solves the problems of conventional valves, i.e. easy abrasion of spools and valve bodies and poor sealing effect. The reversing valve comprises a valve body, a spool and a valve rod, the spool is cylindrical, the valve body is provided with a water inlet and a water outlet, the side of the spool is provided with a spool hole, the seal is arranged between the outer sidewall of the spool and the inner wall of the valve body, and comprises an annular holder and a sealing part fixed on the holder, the sealing part is annular, and the outer side of the sealing part is provided with a plurality of sealing lips which are arranged in parallel and annularly projected. The seal for the reversing valve has the advantages of good sealing effect, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of valves, and relates to a seal, in particular to a seal for a steering valve. Background technique [0002] At present, in the related equipment of industrial and water heating drainage and liquid control systems, the steering valve is widely used due to its advantages of quick switching, convenient operation, small fluid resistance, and simple structure. [0003] In general plumbing drainage and liquid control systems, a steering valve with a cylindrical spool is generally used. When in use, the valve core is used to rotate around the axis of the valve stem to realize on or off and adjust the size of the opening to adjust or open the valve. Shut off plumbing. [0004] For example, a manual three-way water diversion valve [application number: 200420077886.1; authorized announcement number: CN2711479Y] proposed in Chinese patent documents, the valve body is "ten" shape, with a water inlet, two water outlet...
