Description

Technical Field

[0001] This utility model belongs to the field of valve performance testing technology, specifically relating to a testing device for solenoid valves and pneumatic valves. Background Technology

[0002] Pneumatic and solenoid valves are crucial pneumatic components in pneumatic systems. Currently, the pass / fail status of pneumatic and solenoid valves is primarily determined manually by testing their seals and on / off states through air or electricity. This method is cumbersome, inefficient, and lacks safety. Some automated testing equipment is limited in function, unable to adapt to multiple valve types, and cannot achieve rapid and accurate testing; furthermore, it lacks integrated protection design. Therefore, there is an urgent need for a compact, easy-to-operate device that supports multi-valve testing. Utility Model Content

[0007] The upper front part of the cover is provided with at least one solenoid valve switch, and the middle front part is provided with a pause button, a start button and a time relay. The operation interface of each button and relay is exposed on the surface of the cover.

[0008] A power supply and an intermediate relay are fixed on the upper part of the base plate, which forms a closed space with the cover. A terminal block is provided in the middle, and at least one set of solenoid valves is installed at the lower part. The connector of the solenoid valve extends to the outside of the cover.

[0009] Further defining the above scheme, the number of solenoid valve switches is multiple groups, each group independently controls one solenoid valve, for simultaneous testing of different types of valves.

[0010] Further defining the above scheme, the power switch is electrically connected to the time relay, and the time relay is electrically connected to the intermediate relay, used to set the on / off time of the solenoid valve.

[0011] As a further limitation of the above scheme, the power fuse is connected in series in the power input circuit, and the housing is also provided with a power plug connected to the power supply.

[0012] As a further limitation of the above scheme, the bottom of the base plate is provided with support feet and heat dissipation holes.

[0013] As a further limitation of the above scheme, the support leg is an adjustable height elastic support leg.

[0029] Please see Figure 1-5 The embodiments of this utility model are described in detail below.

[0030] Example: A testing device for solenoid valves and pneumatic valves includes a base plate 11 and a housing 6. The housing 6 and the base plate 11 are fixedly connected by screws to form a closed structure. The top of the housing 6 is equipped with a power switch 10, a power fuse 13, and a count reset button 14. The control parts extend outside the housing 6 for easy operation and fuse replacement. At least one solenoid valve switch 4 is provided on the inner front wall of the housing 6. A pause button 2, a start button 5, and a time relay 3 are provided in the middle of the inner front wall. The operating interfaces of each button and relay are exposed on the surface of the housing 6 for easy operation and data recording. A power supply 15 and an intermediate relay 12 are fixed on the upper part of the base plate 11, which forms a closed space with the housing 6. A terminal block 16 is provided in the middle, and at least one set of solenoid valves 7 are installed at the lower part. The connectors of the solenoid valves 7 extend outside the housing 6 for easy pipeline connection.

[0031] Preferably, the number of solenoid valve switches 4 is multiple groups, each group independently controls one solenoid valve 7, for simultaneous testing of different types of valves.

[0032] In this embodiment, four sets of solenoid valves are fully open to test multiple sets of pneumatic control valves or solenoid valves. Each solenoid valve can be controlled separately according to requirements to achieve on / off testing and long-term fatigue testing of various pneumatic control valves or solenoid valves, and to achieve cumulative counting.

[0033] Specifically, the power switch 10 is electrically connected to the time relay 3, and the time relay 3 is electrically connected to the intermediate relay 12, used to set the on / off time of the solenoid valve 7. The power fuse 13 is connected in series in the input circuit of the power supply 15, and the housing 6 is also provided with a power plug 1 connected to the power supply 15.

[0034] Preferably, the bottom of the base plate 11 is provided with support legs 9 and heat dissipation holes. The support legs 9 are height-adjustable elastic support legs. The heat dissipation holes are evenly distributed on the bottom of the base plate 11.

[0035] In this embodiment, the bottom of the base plate is provided with heat dissipation holes and support feet, and is equipped with a power fuse to increase the service life of each component.

[0036] Operating Procedure: Connect the object to be tested to the solenoid valve connector via the water / gas pipeline as required. Press the power switch 10 to power on the time relay 3 and the display screen will light up. Set the test cycle through the time relay 3. Press the solenoid valve switch 4 to power on the solenoid valve 7. Press the start button 5 to start the automatic test. The solenoid valve 7 can automatically run to test the pneumatic control valve or solenoid valve according to the set time and achieve cumulative counting. Press the pause button 2 to stop the solenoid valve 7 from working.

[0037] When changing the type of solenoid valve, the solenoid valve 7 is independently controlled by the corresponding solenoid valve switch 4. This allows for the separate control of each solenoid valve as needed to test various valve types. Tests can be performed on single-pneumatic control valves, double-pneumatic control valves, triple-pneumatic control valves, quadruple-pneumatic control valves, and multiple sets of solenoid valves.

[0038] In this embodiment, the solenoid valve switch 4 is fixed to the inner wall of the housing 6, and all interfaces are located outside the housing 6 to achieve quick connection of the pipeline.

[0039] In this embodiment, if the test object needs to be replaced, the counter can be reset to zero by pressing and holding the counter reset button 14 on the top of the cover.

[0040] The device has a simple overall structure, is easy to install and maintain, saves testing time, and improves work efficiency.
