Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a test pressure adjustment unit. Background Technology

[0002] Pneumatic check valves with reverse opening function can only allow compressed air to flow in one direction and cannot flow back in the opposite direction. If reverse opening is required, other mechanisms must be used to control the opening. They have a wide range of applications. After production, these check valves need to be tested, and the testing frequency is 100%. The testing process requires precise multi-level control and output of test pressure and reverse opening pressure. However, there is currently no test pressure adjustment unit for the testing process of pneumatic check valves with reverse opening function to assist in the testing process of such pneumatic check valves with reverse opening function. Utility Model Content

[0008] Furthermore, the second precision pressure regulating valve, the third precision pressure regulating valve, and the high-pressure regulating valve are disposed on the same side of the combined clamping plate, while the first precision pressure regulating valve is fixedly disposed on the other side of the combined clamping plate. The first precision pressure regulating valve and the high-pressure regulating valve are connected to the combined clamping plate through a double-headed ship plate screw.

[0009] Compared with the prior art, the beneficial effects of this utility model include: by setting a high-pressure regulating valve and several precision pressure regulating valves, all of which are connected to the output end of the high-pressure regulating valve to output different test pressures, and by using clamps and combined clamps in conjunction with through-plate screws to connect the high-pressure regulating valve and several precision pressure regulating valves, the structure is simple and clear. The setting of clamps and combined clamps can effectively prevent pipelines from being exposed on the control panel, which is conducive to the air circuit arrangement below the control panel.
