[0002] A one-way valve, also known as a check valve or a non-return valve, is a fluid control valve whose main function is to allow fluid to flow in one direction while preventing the fluid from flowing in the opposite direction. In the traditional one-way valve design, there are often some problems in the installation process, which may require multiple steps and complex tools, and the installation and maintenance process is cumbersome. For example, a Chinese patent discloses "a one-way valve" with an application number of "202121917289.5". By setting a control mechanism, it can facilitate the control of the one-way fluidity of gas or liquid, and at the same time enable the return spring to work inside the fixed sleeve to avoid direct contact with the transmitted gas or liquid, thereby effectively increasing the service life of the valve. By setting a sealing mechanism, it can promote the transmission efficiency of gas or liquid, and at the same time increase the overall sealing effect of the valve when sealing, thereby effectively increasing the stability of the valve during use. However, the installation and maintenance of the one-way valve may still be cumbersome. Utility Model Content

The valve body 1 is connected with the left joint 2 and the right joint 5, and the valve body 1 is located between the left joint 2 and the right joint 5. The right surface of the right joint 5 is provided with a right connecting groove 6 for installing and fixing the external pipeline.

[0023] The left inner wall of the right connecting groove 6 is fixedly connected with a right sealing ring 12, which is used to seal with the external pipeline to prevent fluid leakage from the connection. The output port 8 is located at the center of the right connecting groove 6. The side inner walls of the left connecting groove 3 and the right joint 5 are both provided with threads for the tightness and strength of the one-way valve connection. The valve body 1 and the inner wall of the right joint 5 are threadedly connected with a support ring 7 for providing an installation basis for the support spring 11 and helping to maintain the position of the valve core 10 in the valve body. The left end surface of the support ring 7 is fixedly connected with a support spring 11 for the valve core 10 provides a reset force, the right end of the support spring 11 is fixedly connected to the left end face of the support ring 7, the end of the support spring 11 away from the support ring 7 is fixedly connected to the valve core 10, the valve core 10 is fixedly connected to the left end of the support spring 11, the support spring 11 and the valve core 10 are both located inside the valve body 1 and on the left side of the output port 8, a sealing port 9 is provided inside the valve body 1, which is the key position of the valve core 10 to control the flow of fluid, when the valve core 10 is closed, it blocks this port to prevent the fluid from passing, and the valve core 10 is located on the right side of the sealing port 9.

[0024] Working principle: the valve body 1 is the main part of the whole one-way valve, connecting the left joint 2 and the right joint 5 to form a fluid channel. The left joint 2 and the right joint 5 are respectively provided with a left connecting groove 3 and a right connecting groove 6 to provide connection with the external pipeline. The left connecting groove 3 and the right connecting groove 6 are connected to the left inner wall and the left inner wall of the left sealing ring 13 and the right sealing ring 12 to ensure the sealing of the connection. The inner walls of both are provided with threads to improve the tightness and strength of the one-way valve connection through double threads. The support ring 7 is connected to the inner wall of the valve body 1 and the right joint 5 by threads. One end of the support spring 11 is fixed on the support ring 7, and the other end is connected to the valve core 10 to provide a reset force for the valve core 10. The center of the left joint 2 and the right joint 5 is divided into a circle. An input port 4 and an output port 8 are separately provided, which are the main channels for fluid to enter and exit. When the fluid enters the valve body 1 from the input port 8 on the left joint 2, the fluid will act on the valve core 10 to generate a thrust to the right. If the pressure of the fluid is large enough to overcome the elastic force of the supporting spring 11, the valve core 10 will be pushed to the right, thereby opening the blocking port 9, allowing the fluid to pass through and flow to the output port 8 on the right joint 5. In this process, the left sealing ring 13 and the right sealing ring 12 ensure that the fluid will not leak from the connection. When the fluid tries to flow back into the valve body 1 from the output port 8 on the right joint 5, the valve core 10 has been reset and blocked the blocking port 9 under the elastic force of the supporting spring 11, so the fluid cannot pass directly.
