[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] like Figure 1-3 As shown, the component includes a hollow air circuit block 1, on which five groups of two-way solenoid valves 2 are arranged side by side, wherein each group of two-way solenoid valves 2 has two and are respectively arranged on both sides of the air circuit block 1 (referred to as the left and right sides). At the same time, five ventilation pipes 3 extending left and right are arranged side by side inside the air circuit block 1, and the two ends of each ventilation pipe 3 are respectively connected to the two two-way solenoid valves 2 of each group.

[0016] Preferably, the gas circuit block 1 is made of high-strength, corrosion-resistant stainless steel, and a certain number and size of mounting openings 6 are provided on the left and right side surfaces, the bottom surface and other side surfaces according to the requirements of the test process.

[0017] Preferably, a sealing ring 5 is provided on each two-way solenoid valve 2 to completely seal the installation thereof on the gas circuit block 1 .

[0018] Taking one set of two-way solenoid valves 2 and the connected vent pipe 3 as an example, the left and right ends of the vent pipe 3 are respectively connected to one end of the two two-way solenoid valves 2, while the middle of the vent pipe 3 and the other ends of the two two-way solenoid valves 2 are respectively connected to three self-sealing connectors 4 extending outside the air circuit block 1. The self-sealing connector 4 connected to the middle of the vent pipe 3 can be connected to a calibration leak, leak detector, air pipe, etc. as needed, while the self-sealing connector 4 connected to the two two-way solenoid valves 2 is used to connect to the pipeline of the test station.

[0019] In addition, one end of the vent pipe 3 is mounted on the gas circuit block 1 and is blocked by a plug 7 , which is mounted on the mounting port 6 of the gas circuit block 1 .

[0020] Preferably, each sealing joint 4 is made of stainless steel and is installed on the installation port 6 of the gas circuit block 1 .

[0021] The two self-sealing connectors 4 connected to the two two-way solenoid valves 2 in each group of the assembly are used to connect two different test stations respectively. By controlling the on and off of the two two-way solenoid valves 2, various functional tests can be performed on the two test stations respectively.

[0022] Among them, five groups of two-way solenoid valves 2 are respectively connected to the interfaces for testing, calibration, breaking air, purging positive pressure, and purging negative pressure on each test station, and can be used for testing, calibration, breaking air, purging positive pressure, purging negative pressure and other functional tests at each test station.

[0023] When performing functional tests such as testing, calibration, breaking air, purging positive pressure, and purging negative pressure on the two test stations, first connect the two self-sealing connectors 4 connected to the two two-way solenoid valves 2 to the corresponding interfaces of the two test stations; then connect the self-sealing connector 4 in the middle of the vent pipe 3 to the corresponding detection equipment, such as connecting to a leak detector when conducting a test, and connecting to a calibration leak hole when conducting a calibration.

[0024] Then, when the test station connected to the left needs to be functionally tested, the two-way solenoid valve 2 on the right is closed and the two-way solenoid valve 2 on the left is opened, so that the test station connected to the left can be functionally tested; when the test station connected to the right needs to be functionally tested, the two-way solenoid valve 2 on the left is closed and the two-way solenoid valve 2 on the right is opened, so that the test station connected to the right can be functionally tested. In this way, the functional tests between the two test stations can be independent of each other without affecting each other.

[0025] In addition, when performing functional tests such as calibration, breaking air, and blowing positive pressure, the airflow direction in the component is the vent pipe 3, the two-way solenoid valve 2, and the test station, and when performing functional tests such as testing and blowing negative pressure, the airflow direction in the component is the test station, the two-way solenoid valve 2, and the vent pipe 3.

[0026] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
