Problems solved by technology
The current detection equipment valve is not convenient enough to fix, and at the same time, high-pressure water is passed into the valve to be tested, which requires special liquid pressurization equipment, which makes the detection equipment more complicated and costly.
And these supercharging devices usually use electric shock control, so that in the absence of electricity, the test work of the machine cannot be carried out

Embodiment Construction
[0016] Below in conjunction with embodiment the present invention is further described:
[0017] Such as figure 1 As shown in the embodiment, this small-scale hydrostatic precision manual control testing machine includes a fixed frame plate 1, a connecting sliding shaft 2, a sliding pressure plate 3, a push screw rod 4, and a booster rod 5. The fixed frame plate 1 is two Blocks are placed vertically opposite each other. In this embodiment, the number of connecting sliding shafts 2 is four, and they are vertically connected between two fixed frame plates 1. The sliding pressure plate 3 is slidably assembled on the fixed frame plate 1. on the connecting sliding shafts 2 between them; the four connecting sliding shafts 2 are respectively assembled at the four corner positions of the sliding pressing plate 3, so that the sliding pressing plate 3 runs more stably on the connecting sliding shafts 2 . The sliding pressing plate 3 is rotatably assembled with one end of the pushing s...

The invention provides a small-range hydrostatic precise manual control testing machine, which comprises fixing frame plates, connecting sliding shafts, a sliding pressing plate, a pushing screw rod and a pressurizing rod, wherein the sliding pressing plate is slidably assembled on the connecting sliding shafts between the fixing frame plates; one end of the pushing screw rod penetrates one fixing frame plate, and is in threaded assembly with a push fixing block fixed on one fixing frame plate; a smooth shaft of the pressurizing rod penetrates a valve positioning block and extends into an inner cavity of a valve, and the smooth shaft of the pressurizing rod is in sliding seal assembly with the valve; and the upper part of the valve is connected with a liquid feeding device and a pressure testing device at a position when a hand wheel is assembled. The sliding pressing plate is controlled through the hand wheel, and pressurization of the valve is realized by rotating the pressurizing hand wheel, the structure is simple, all operations can be finished manually, and the small-range hydrostatic precise manual control testing machine overcomes the dependence of valve sealing tests on valves.
Description
technical field [0001] The invention relates to the technical field of testing machinery, in particular to a small-scale hydrostatic precise manual control testing machine. [0002] Background technique [0003] After the production of the valve is completed, it is necessary to carry out various tests on whether the valve meets the specification requirements. One of the hydraulic tests is also called the shell test to test the waterproofness of the valve and the external waterproofness of the valve cock. This test mainly uses medium to rush into the valve with high pressure to simulate the high pressure environment in which the valve is used, and then judges whether the test valve meets the requirements by detecting whether the valve medium leaks. The test medium is usually water, air or helium; when the pressure to be tested is high, it is best to test with water, because water can accumulate energy as little as possible. [0004] When using the medium water test, it is n...
