[0029] In the above embodiment, the valve pressure test platform can be formed by welding the top seat 3, the base 1 and the vertical rod 2. At the same time, this structure is relatively simple and easy to manufacture, and can meet the requirements of basic valve pressure testing.

[0030] Furthermore, the push rod 5 is fixedly installed on the top seat 3 , and the pressure test valve 7 is movably installed in the middle of the upper surface of the base 1 .

[0031] Through the cooperation of the jack 61 of the pressure test mechanism 6 and the push rod 5, the upper pressure cover 62 can be fitted with the upper end of the valve. At the same time, under the action of the jack 61, the pressure test valve 7 can be fixed on the lower pressure cover 10 on the upper surface of the base 1.

[0032] See also Figure 1 、 Figure 2 and Figure 3 In this embodiment, the bracket 4 is a channel steel, and the bracket 4 is welded to both sides of the bottom of the base 1. Four groups of pulleys 9 are provided and fixedly installed on both sides of the inside of the bracket 4 respectively.

At this time, the pressure test valve 7 is in a partially open state. The upper and lower ends of the pressure test valve 7 are aligned with the middle of the upper pressure cover 62 and the lower pressure cover 10. At the same time, sealing rubber gaskets are installed at both ends of the pressure test valve 7. The sealing gaskets are compressed by the jack 61 to ensure that the sealing is intact. After the pressure test preparation is completed, the pressure test valve body 7 is filled with the test medium by connecting the pressurization port 63 to the manual pressure test pump. When the gas in the pressure test valve 7 is exhausted, the drain valve below is closed to close the drain port 8.
