Drawings
Fig. 1 is a schematic diagram of a preferred overall structure of a high-pressure connecting pipe type buffering check valve in the utility model.
In the figure: 1. taking over a pipe; 2. a gasket; 3. a pipe connecting nut; 4. a fitting body; 5. an O-shaped sealing ring; 6. a valve flap; 7. a valve core; 8. a buffer adjustment spring; 9. a valve body.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1, the high-pressure receiving pipe type buffer check valve includes a valve body 9, wherein two ends of the valve body 9 are provided with connecting pipes 1, a connector body 4 is arranged between one of the connecting pipes 1 and the valve body 9, a valve core 7 and a buffer adjusting spring 8 are arranged between the connector body 4 and the inside of the valve body 9, one end of the buffer adjusting spring 8 is connected with the inside of the valve body 9, the other end of the buffer adjusting spring is connected with the valve core 7, and the valve core 7 blocks a medium circulation port inside the valve body 9.
In the present embodiment, a gasket 2 is provided between the adapter tube 1 and the coupling body 4 or the valve body 9. Thereby the connection between the adapter tube 1 and the connector body 4 or the valve body 9 is firmer and the sealing performance is better.
In the present embodiment, the adapter 1 and the adapter body 4 or the valve body 9 are screwed together. The connection between the adapter tube 1 and the adapter body 4 or the valve body 9 is facilitated, so that the connection is quicker.
In the present embodiment, an O-ring seal 5 is provided between the valve body 9 and the joint body 4. The design of the O-shaped sealing ring 5 ensures that the sealing performance between the valve body 9 and the joint body 4 is better.
In the embodiment, the joint body 4 and the valve body 9 are in threaded connection. The connection between the abutment body 4 and the valve body 9 is facilitated so that it can be quickly disassembled and assembled.
In the present embodiment, a valve flap 6 is provided on the valve element 7, and the valve flap 6 is connected to a damping adjustment spring 8. Therefore, the valve core 7 can be better protected, and the valve clack 6 wraps the valve core 7 in a semi-surrounding mode.
Example two:
in summary, as shown in fig. 1, during normal circulation, the valve core 7 is pushed by a medium pressure medium flowing in from the left side to extrude the valve core 7, the valve core 7 extrudes the buffer adjusting spring 8 to move the valve core 7 inwards, and then the valve core 7 no longer blocks a medium delivery port inside the valve body 9, the medium flows from the left connection pipe 1 to the other connection pipe 1 through a delivery channel inside the valve body 9, and the valve is in an open state.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
