Description

Technical Field

[0001] The utility model relates to the technical field of oil outlet valves, in particular to an isobaric oil outlet valve pair. Background Art

[0002] The oil outlet valve is a one-way valve. Under the action of spring pressure, the conical surface on the upper part of the valve fits tightly with the valve seat. Its function is to isolate the high-pressure oil pipe from the cavity on the upper end of the plunger when the supply is stopped, preventing the oil in the high-pressure oil pipe from flowing back into the injection pump.

[0003] In the prior art, the oil outlet valve acts as a one-way valve, which can only allow oil to flow out but not in. The oil outlet valve pair is mainly composed of a valve body, a valve core and a spring, and is mainly used to control the flow of fluid. During the use of the existing isobaric oil outlet valve pair, the oil outlet valve gasket is easily damaged. Once the oil outlet valve plate is damaged, oil leakage, insufficient oil pressure, insufficient oil injection, etc. are likely to occur. The oil outlet valve gasket is also prone to deformation. Once the oil outlet valve plate is deformed, the oil outlet valve is likely to be stuck, and high-pressure oil cannot be generated. Therefore, we propose an isobaric oil outlet valve pair. Utility Model Content

The oil outlet valve pair is mainly composed of a valve body, a valve core and a spring, and is mainly used to control the flow of fluid. During the use of the existing isobaric oil outlet valve pair, the oil outlet valve gasket is easily damaged, and after the oil outlet valve plate is damaged, oil leakage, insufficient oil pressure, insufficient oil injection, etc. are likely to occur. The oil outlet valve gasket is also prone to deformation. Once the oil outlet valve plate is deformed, it is easy to cause the oil outlet valve to get stuck, and high-pressure oil cannot be generated.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An isobaric oil outlet valve assembly includes an oil outlet valve seat, the interior of the oil outlet valve seat extends to the top where a valve core is clamped, the top of the valve core is fixedly connected to a valve cap, and the bottom of the valve cap, located on the periphery of the valve core, is fixedly connected to a gasket assembly;

[0013] As a preferred solution of the present invention, the first buffer gasket is made of rubber material, and the first elastic material is made of silicone material.

[0014] The technical effect of adopting the above-mentioned further scheme is: by filling the first elastic material made of silicone material into the interior of the first buffer gasket, the elasticity of the first buffer gasket can be effectively increased, thereby effectively improving the buffering performance of the first buffer gasket, thereby effectively preventing the oil outlet valve gasket body from being deformed during use, and at the same time protecting one side of the oil outlet valve gasket body to prevent the oil outlet valve gasket body from being stretched.

[0015] As a preferred solution of the present invention, the connecting layer is made of rubber material, and the oil outlet valve gasket body is made of copper material.

[0016] As a preferred solution of the present invention, the second buffer gasket is made of rubber material, and the second elastic material is made of silicone material.

[0017] The technical effect of adopting the above further solution is that the second buffer gasket made of rubber material has good elasticity, thereby being able to effectively protect the oil outlet valve gasket body and prevent the oil outlet valve gasket body from being damaged.

By protecting both sides of the oil outlet valve gasket body, the oil outlet valve gasket body can be effectively prevented from being deformed and stretched, thereby effectively improving the service life of the oil outlet valve gasket body. The first elastic material and the second elastic material can further improve the strength of the first buffer gasket and the second buffer gasket, thereby ensuring the protection of the oil outlet valve gasket body.

[0031] like Figure 1-5 As shown, the utility model provides a technical solution: an isobaric oil outlet valve pair, including an oil outlet valve seat 1, the interior of the oil outlet valve seat 1 extends to the top where a valve core 2 is clamped, the top of the valve core 2 is fixedly connected to a valve cap 3, the bottom of the valve cap 3 and the periphery of the valve core 2 are fixedly connected to a gasket assembly 4, the gasket assembly 4 includes an oil outlet valve gasket body 41, the top of the oil outlet valve gasket body 41 is bonded with a first buffer gasket 42, the interior of the first buffer gasket 42 is filled with a first elastic material 43, the top of the first buffer gasket 42 is coated with a connecting layer 44, the first buffer gasket 42 is bonded to the valve cap 3 through the connecting layer 44, the bottom of the oil outlet valve gasket body 41 is bonded with a second buffer gasket 45, and the interior of the second buffer gasket 45 is filled with a second elastic material 46.

[0032] Example 2

[0033] like Figure 1-5 As shown, a cross-guide valve core body 21 is fixed to the bottom of the valve core 2, and guide blocks 22 are symmetrically fixed on both sides of the protruding part of the cross-guide valve core body 21. The sliding connection between the guide blocks 22 and the guide grooves 11 can effectively improve the stability of the cross-guide valve core body 21.

[0034] A guide groove 11 is provided inside the oil outlet valve seat 1 corresponding to the guide block 22 , and the guide block 22 is slidably connected to the guide groove 11 . Oil passing grooves 12 are provided adjacent to the guide grooves 11 . The setting of the oil passing grooves 12 facilitates the passage of oil through the oil outlet valve seat 1 .

[0035] The oil outlet valve seat 1 is made of alloy steel. The alloy steel has high strength and can effectively improve the wear resistance and corrosion resistance of the oil outlet valve seat 1.

[0036] The valve core 2 is made of hard alloy, and the surface of the valve core 2 is spray-coated. The hard alloy itself has high strength, and the spray-coating process can effectively ensure corrosion resistance and wear resistance, thereby effectively improving the service life.

[0037] The first buffer gasket 42 is made of rubber, and the first elastic material 43 is made of silicone, which can effectively protect the oil outlet valve gasket body 41.

[0038] The connecting layer 44 is made of rubber material, and the oil outlet valve gasket body 41 is made of copper material. The oil outlet valve gasket body 41 made of copper material has good strength and is not easy to deform.

[0039] The second buffer gasket 45 is made of rubber, and the second elastic material 46 is made of silicone, which can cooperate with the first buffer gasket 42 and the first elastic material 43 to protect the oil outlet valve gasket body 41.

[0040] The working process of the utility model is as follows: when using an isobaric oil outlet valve pair, first, when the valve core 2 and the cross guide valve core body 21 are impacted and lifted up, the oil will pass through the inner guide groove 11 and the oil groove 12 of the oil outlet valve seat 1, and when the valve core 2 is lifted up, the gasket assembly 4 is also lifted up at the same time. After being lifted up, when the oil supply is terminated, the valve core 2 will reset, and when resetting, the second buffer gasket 45 will be impacted, and the impact of the second buffer gasket 45 will prevent the oil outlet valve gasket body 41 from being impacted, and When the second buffer gasket 45 receives an impact, the second elastic material 46 also performs buffering, while the first buffer gasket 42 and the first elastic material 43 on the other side also play a buffering role. In this way, the oil outlet valve gasket body 41 located in the center position can be well protected, thereby effectively preventing the oil outlet valve gasket body 41 from being deformed and strained. The design of the present invention can effectively prevent the oil outlet valve gasket from being strained and deformed during use, thereby effectively ensuring that the isobaric oil outlet valve pair can operate normally.
