Description

Technical Field

[0001] The utility model belongs to the technical field of pressure reducing valve testing, in particular to a precision performance comprehensive testing workbench for pressure reducing valves. Background Art

[0002] A pressure reducing valve is a valve that reduces the inlet pressure to a required outlet pressure through regulation, and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. From the viewpoint of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction. Then, by relying on the regulation of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve is kept constant within a certain error range. The pressure reducing valve reduces the water pressure by the local resistance of the flow channel inside the valve to the water flow, and the range of the water pressure drop is automatically adjusted by the inlet and outlet water pressure difference on both sides of the film or piston connecting the valve disc.

[0003] After the pressure reducing valve is prepared, it is often necessary to conduct a comprehensive precision performance test on the pressure reducing valve, which requires the use of a pressure reducing valve precision performance comprehensive test workbench. The existing comprehensive test workbench is used to test the pressure reducing valve. Generally, the pressure reducing valve is placed on the workbench, and then the metal pipe is installed on the air inlet and outlet of the pressure reducing valve to test the pressure reducing valve.

[0004] However, when most of the existing pressure reducing valve precision performance comprehensive testing workbenches are used to test the pressure reducing valve, the pressure reducing valve and the metal pipe are generally installed by plugging. As a result, the pressure reducing valve cannot be clamped by the workbench, causing the pressure reducing valve to shake during the test, which may cause the metal pipe to separate from the pressure reducing valve, resulting in interruption of the pressure reducing valve test. Therefore, a pressure reducing valve precision performance comprehensive testing workbench is proposed. Utility Model Content

The installation of the pressure reducing valve body 4 is completed, and the workbench 1 is turned on by the switch button, and the gas is input into the interior of the pressure reducing valve body 4 through the metal tube 2.
