Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations set forth in the following description of the specific embodiments.

In the first embodiment, please refer to fig. 1-4, the present invention provides a technical solution: the utility model provides a check valve, includes valve body 1 and the inside spring 5 and the case 3 that sets up thereof, and the both ends of valve body 1 are connected with suction nozzle 2 and play gas nozzle 4 respectively, and suction nozzle 2 and play gas nozzle 4 all with 1 threaded connection of valve body, the junction between suction nozzle 2 and the valve body 1 sets up sealing washer 6, and the junction of going out gas nozzle 4 and valve body 1 also sets up sealing washer 6.

Referring to fig. 1-4, the air inlet nozzle 2 is provided with a conical cavity 2.2 for accommodating the conical valve core 3, the air inlet 2.1 is arranged inside the air inlet nozzle 2, the air inlet 2.1 and the conical cavity 2.2 are mutually communicated to form an air inlet channel, the spring 5 is arranged between the valve core 3 and the air outlet nozzle 4, the conical cavity 2.2 is used for accommodating the cone 3.1 of the valve core 3, the valve core 3 is composed of the cone 3.1 and a shaft body 3.2, the shaft body 3.2 is used for sleeving the spring 5, the air outlet 4.1 and a through hole 4.2 are arranged inside the air outlet nozzle 4, and the outside of the through hole 4.2 is arranged as a shaft barrel 4.3.
