Background technology

At present, the performance of hand control valve mainly is to detect (or the simple and easy stand of temporarily building detects) at valve class multi-function test stand stand, owing to there is not special-purpose testing table, test after the handle of hand control valve need being pulled down, can not simulate the real vehicle applying working condition fully and test, influence the authenticity of test findings, cause under a lot of situations, the endurance issues of hand control valve needs just to expose in complete vehicle test or car load use, and cost of development is strengthened, and the construction cycle lengthens greatly.

Summary of the invention

The purpose of this utility model is that design a kind ofly can simulate the real vehicle applying working condition fully, provide source of the gas to the test exemplar, and test exemplar action is loaded a kind of automobile hand control valve endurancing Pneumatic loading that drives source of the gas is provided.

The technical solution of the utility model is achieved in that automobile hand control valve endurancing Pneumatic loading of the present utility model comprises source of the gas, test exemplar air feed loop, action drives air feed loop, its test exemplar air feed loop comprises first pressure adjusting pressuring valve, first rain glass, first gas tank, first separating switch that is connected successively by pipeline, to testing exemplar; Action drives air feed loop comprises that oscillating cylinder drives loop and vertical air cylinder driven loop; Oscillating cylinder drives the loop and comprises second pressure adjusting pressuring valve, second rain glass, second gas tank, second separating switch, second solenoid valve that is connected successively by pipeline, to oscillating cylinder; Vertically the air cylinder driven loop comprises the 3rd pressure adjusting pressuring valve, the 3rd rain glass, the 3rd gas tank, the 3rd separating switch, the 3rd solenoid valve that is connected successively by pipeline, to vertical cylinder.

Described automobile hand control valve endurancing Pneumatic loading is all established 1～5 outlet by first gas tank, second gas tank, the 3rd gas tank, is divided into 1～5 output loop respectively.

The utility model patent has the following advantages:

1, in the control gas circuit, use two 20L gas tanks, a loading air feed that is used for vertical actuating cylinder, a loading air feed that is used for oscillating cylinder makes the gas circuit stable gas pressure.

2, independently pressure-regulating valve and rain glass of each loop, the expulsive force that is used for regulating gas circuit air pressure and cylinder.

3, independently separating switch of each loop, in case lost efficacy in certain loop, or exemplar has problem, can stop separately, do not influence the work in other exemplar and loop.

4, each exemplar adopts independent solenoid valve, is convenient to control respectively and count, and can independently control the test of single exemplar.

5, in the input gas circuit of hand control valve, use a 30L gas tank, be used for the loading air feed of three exemplars, and guarantee stable gas pressure.
