Abstract
The utility model relates to a kind of high-low temperature cylinder valve life test platform, comprises the test fixture for installing cylinder valve to be measured, and the air intake opening of described test fixture is connected with reduction valve, retaining valve and gas admittance valve in turn; The gas outlet of described test fixture is connected with emptying needle-valve; Described servomotor is for controlling the switch of cylinder valve to be measured.The utility model can be tested the durability of cylinder valve.
Description
Technical field
The utility model relates to cylinder valve technical field of measurement and test, particularly relates to a kind of high-low temperature cylinder valve life test platform.
Background technology
Cylinder valve is the valve controlling gas turnover in gas cylinder.Domestic cylinder valve structure is divided into three kinds: one is flapper-type, and one is diaphragm type, also has a kind of needle-like formula.Diaphragm valve gas residence is good, but easily damages, and serviceable life is short.Therefore adopt flapper-type valve and needle-like formula valve at present more.
The resistance to pressure of cylinder valve, durability, impermeability and resistance to impact are all weigh the standard of cylinder valve quality.By when 1.2 times of nominal operating pressures in prior art, valve is in cut out and any opening at least pressurize one minute No leakage, when 0.05MPa pressure, valve is in cut out and any opening, and at least the impermeability of pressurize one minute leak free mode to cylinder valve is tested; By bearing 4 times of nominal operating pressures under working pressure, at least pressurize five minutes without permanent strain and the resistance to pressure of leak free mode to cylinder valve test.But also not to the device that the durability of cylinder valve is tested in prior art.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-low temperature cylinder valve life test platform, can test the durability of cylinder valve.
The utility model solves the technical scheme that its technical matters adopts: provide a kind of high-low temperature cylinder valve life test platform, comprise the test fixture for installing cylinder valve to be measured, the air intake opening of described test fixture is connected with reduction valve, retaining valve and gas admittance valve in turn; The gas outlet of described test fixture is connected with emptying needle-valve; Described servomotor is for controlling the switch of cylinder valve to be measured.
The air intake opening of described test fixture is connected by high-pressure hose with between reduction valve.
The exit of described reduction valve is provided with tensimeter.
The gas outlet of described test fixture is connected by emptying flexible pipe with between emptying needle-valve.
Also delivery gauge is provided with between the gas outlet of described test fixture and emptying needle-valve.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model regulates test pressure by reduction valve, the switch of cylinder valve to be measured is controlled by servomotor, thus the test achieved cylinder valve durability, accurately can test out the life-span of cylinder valve to be measured.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment of the present utility model relates to a kind of high-low temperature cylinder valve life test platform, and as shown in Figure 1, comprise the test fixture 1 for installing cylinder valve to be measured, the air intake opening of described test fixture 1 is connected with reduction valve 2, retaining valve 3 and gas admittance valve 4 in turn; The gas outlet of described test fixture 1 is connected with emptying needle-valve 5; Described servomotor is for controlling the switch of cylinder valve to be measured.Wherein, the air intake opening of described test fixture 1 is connected by high-pressure hose 7 with between reduction valve 2, utilizing high-pressure hose 7 to connect can prevent hypertonia from causing pipeline breaking, and is provided with tensimeter 6 in the exit of described reduction valve 2, can Real Time Observation test pressure by tensimeter 6.The gas outlet of described test fixture 1 is connected by emptying flexible pipe 9 with between emptying needle-valve 5, is also provided with delivery gauge 8 between the gas outlet of described test fixture 1 and emptying needle-valve 5.
Principle of work of the present utility model is as follows: high-pressure air source enters experiment porch by air inlet ball valve, first decompression pressure regulating valve is passed through to test pressure, platform test frock is entered by air inlet high-pressure hose, Serve Motor Control cylinder valve switch to be measured, valve life testing is carried out by repeatedly opening closedown cylinder valve to be measured, under exhaust mode, be vented by emptying flexible pipe and rear end needle-valve emptying.
Working pressure of the present utility model is 44.8MPa, actuating medium is nitrogen or air, conduit operating temperature controls between-50 DEG C ~ 100 DEG C, the moment of torsion of servomotor is adjustable within the scope of 0 ~ 20N*M, the rotating speed of servomotor is adjustable, and the angle of rotation aperture of servomotor is adjustable, and servomotor upper-lower height is adjustable, the highest inlet pressure of reduction valve is 68.9MPa, and reduction valve top hole pressure is 0.34MPa ~ 41.3MPa.
Be not difficult to find, the utility model regulates test pressure by reduction valve, is controlled the switch of cylinder valve to be measured by servomotor, thus achieves the test to cylinder valve durability, accurately can test out the life-span of cylinder valve to be measured.
