[0003] The existing valve assembly such as patent application number CN202322326956.8 discloses an elastic guide ring, moving iron core guide structure and solenoid valve, and patent application number CN202410944577.1 discloses an air spring stiffness valve core assembly and air spring stiffness valve, and most of the valves on the market such as Figure 1 And Figure 2 As shown, it is made by the process of coating adhesive on the metal framework and then vulcanizing, and the rubber parts of the front section of the valve assembly and the valve seat are continuously impacted during the working process of the stiffness valve, and after 100-300 thousand times of impact, the rubber can appear the phenomenon of rupture and falling off, thereby leading to product failure, and the service life cannot reach 130 thousand times of use requirement. UTILITY MODEL CONTENT

[0004] The utility model solves the technical problem to provide a high strength stiffness valve valve structure, its simple structure reduces the risk of rubber falling off and rupture, reduces the deformation amount of rubber, improves the strength, thereby reaches the requirement of product service life.

[0005] To solve the above problem, the utility model adopts the following technical scheme:

[0006] A high strength stiffness valve valve structure, the valve seat and the rubber part, the valve seat side end is distributed with annular groove along annularly, the rubber part is embedded in annular groove, and the bottom end of annular groove is inverted "trapezoidal".

[0007] Further technical scheme is that the annular groove includes annular outer groove and annular inner groove, the annular outer groove is located the outer side of annular inner groove and is interconnected, and the annular inner groove is inverted "trapezoidal", the rubber part can be embedded in annular groove and is not easy to fall off through annular inner groove, and the rubber part at annular outer groove mainly plays the impact bearing role.

[0008] Further technical scheme is that the adhesive (not shown) is further distributed between the valve seat and the rubber part, and the connection strength is increased.

[0009] The utility model has the advantages of:

[0010] The utility model discloses a high strength rigidity valve valve structure, and the valve seat completely wraps rubber part, can reduce the deformation degree of rubber in the impact process, improves the strength, simultaneously, the annular groove bottom end on the valve seat is inverted "trapezoidal" structure, reduces the risk of rubber peeling, fracture, to reach the purpose of improving product life.

[0020] The preferred embodiments of the utility model are described in detail below, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined.

[0021] Reference Figures 3 to 7As shown, a high-strength rigidity valve structure comprises a valve seat 1 and a rubber part 2, the valve seat 1 is provided with an annular groove 3 at the side end along the annular direction, the rubber part 2 is embedded in the annular groove 3, and the bottom end of the annular groove 3 is in the shape of an inverted "trapezoid".

[0022] The annular groove 3 comprises an annular outer groove 31 and an annular inner groove 32, the annular outer groove 31 is located outside the annular inner groove 32 and is in communication with each other, the annular inner groove 32 is in the shape of an inverted "trapezoid", and the rubber part 2 can be embedded in the annular groove 3 and is not easy to fall off through the annular inner groove 32, and the rubber part 2 located at the annular outer groove 31 mainly plays a role of bearing impact. An adhesive (not shown) is further distributed between the valve seat 1 and the rubber part 2 to increase the connection strength.

[0023] In the embodiment, the new valve seat 1 is provided with the annular groove 3 at the front end in addition to the adhesive used to bond the metal and the rubber together, the annular inner groove 32 is in the shape of an inverted "trapezoid" with a large bottom size and a small mouth size, which can effectively prevent the rubber part 2 from being separated from the valve seat 1 made of metal material, such as Figure 7 A schematic view of the structure installed on a rigidity valve is shown, wherein the rubber part 2 is wrapped by the valve seat 1 and continuously impacts on a valve seat sealing sleeve 4.

[0024] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any change or replacement without creative labor should be covered in the protection scope of the present application.
