Description
Technical Field
The utility model relates to the technical field of petroleum machinery, in particular to novel super high pressure automatic re-setting plane sealing check valve.
Background
The check valve is commonly called as a check valve, fluid can only flow along the water inlet, and the medium at the water outlet cannot flow back. Check valves are also known as check valves or check valves. For preventing reverse flow of oil in hydraulic systems or for preventing reverse flow of compressed air in pneumatic systems. The one-way valve has a straight-through type and a right-angle type. The straight-through one-way valve is installed on the pipeline by threaded connection. The right-angle check valve has three forms of threaded connection, plate connection and flange connection. The check valve is often needed to be used in the connection of petroleum machinery pipelines, and the existing check valve has the problem of poor sealing property and cannot meet the use requirement.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel super high pressure automatic re-setting plane sealing check valve to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel superhigh pressure automatic re-setting plane sealing check valve, includes the valve body, the one end of valve body is provided with the union tight cap, and the other end of valve body is provided with the valve gap, be provided with the valve clack in the valve body, and valve clack department still is provided with the spring, the spring winding still is provided with the valve clack holding ring on the flow direction sign, and one side in the valve body, the valve clack holding ring sets up the one end that is located the flow direction sign in the valve body.
As a further improvement to the technical scheme, the union nut is connected with the valve body through a clamping sleeve, and a check ring is further arranged at the clamping sleeve.
As a further improvement to the technical scheme, the valve cover is connected with the valve body through a cone-end set screw, and an O-shaped ring is further arranged at the cone-end set screw.
As a further improvement to the technical scheme, the surface of the valve body is provided with a rivet.
As a further improvement on the technical scheme, a sealing ring is further arranged on the contact surface of one side of the valve clack and the inner wall of the valve body.
As a further improvement to the above technical solution, the seal ring is any one of a rubber seal ring and a metal seal ring.
