Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of the valve test, especially, relate to a direct-acting overflow valve test device.
[ background of the invention ]
All existing hydraulic equipment is provided with overflow valves for limiting hydraulic pressure and protecting equipment. The direct-acting overflow valve is divided into four common specifications of 06mm, 10mm, 20mm and 30mm according to the drift diameter; each specification has six common pressure specifications of 25bar, 50bar, 100bar, 200bar, 315bar and 400 bar. When a new overflow valve is replaced or installed, the pressure needs to be calibrated according to the requirements of the drawing. However, no such dedicated calibration device is available in the prior art.
Therefore, it is necessary to provide a new direct relief valve testing apparatus to solve the above problems.

In the embodiment, the testing structure is provided with four groups of overflow valves which respectively correspond to four specifications of 06mm, 10mm, 20mm and 30 mm.
The highest pressure provided by the manual pump 2 is greater than or equal to 600bar, and the upper limit of the pressure display range of the electronic pressure gauge 3 is greater than or equal to 600 bar.
In this embodiment, the manual pump 2 is used for providing a hydraulic source for the test, and in other embodiments, other hydraulic devices, such as an automatic hydraulic pump, a hydraulic cylinder, and the like, may be used.
In this embodiment, the pressure is tested by the electronic pressure gauge 3, and in other embodiments, other pressure testing devices may be adopted, and this scheme is not limited.
During testing, the overflow valve to be tested is mounted on the corresponding overflow valve mounting valve hole 4 according to the specification of the overflow valve, then the output pipe of the manual pump 2 is communicated with the corresponding connecting terminal, and the electronic pressure gauge 3 is mounted on the corresponding pressure measuring point 6; and then the manual pump 2 is pressed to observe the overflow outlet 7, and when liquid overflows from the overflow outlet 7, the reading of the electronic pressure gauge 3 is the protection pressure threshold of the overflow valve to be tested.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
