Description
Technical Field
The utility model relates to a measurement system is leaked to the hydrovalve, especially relates to measurement system is leaked to the higher hydrovalve of precision.
Background
The hydraulic valve is a common industrial device, and generally has the problem of leakage when in use, the detection method in the prior art generally adopts two flowmeters with different specifications for detection, a large flowmeter detects the flow of the whole system, and a small flowmeter detects the flow when in leakage and is respectively controlled by stop valves. Meanwhile, any flowmeter is of a positive displacement type, and counts by displacement, so that inaccurate detection is caused due to volume loss, and the price is high.
Disclosure of Invention
An object of the utility model is to provide a high accuracy hydrovalve leaks measurement system, has higher measuring accuracy to the hydrovalve among the prior art leakage measurement accuracy is not enough, and the loaded down with trivial details problem of measuring method and equipment, and measuring equipment is simple.
In order to achieve the above object, the utility model adopts the following technical scheme:
a high-precision hydraulic valve leakage measuring system comprises an inspection oil cylinder, a displacement sensor, an information acquisition system and an information analysis system which are sequentially connected, wherein the inspection oil cylinder is linked with the displacement sensor through a piston rod I; the reset oil cylinder is further connected with an electromagnetic directional valve, and the piston rod II is driven to move through the electromagnetic directional valve.
In the leakage measuring system of the high-precision hydraulic valve, two travel switches are further arranged and are used for respectively controlling the movement of the piston rod II in two directions.
In the above high-precision hydraulic valve leakage measuring system, further, the displacement sensor is a sensor with a precision of not more than 0.01 mm.
The working principle of the high-precision hydraulic valve leakage measuring system is as follows: the inspection oil cylinder is connected with the test piece, when leakage occurs, hydraulic oil flows into the inspection oil cylinder, a piston rod I of the inspection oil cylinder moves leftwards, a displacement sensor linked with the inspection oil cylinder captures a moving signal, the information acquisition system acquires the signal, the information analysis system further analyzes the signal, the signal is converted into data, and whether the test piece is qualified or not is judged. After the test is finished, the piston rod II of the reset oil cylinder is pushed by the electromagnetic directional valve to move rightwards, the piston rod I of the inspection oil cylinder is pushed back to reset, the push-back position is controlled by one travel switch, and the other travel switch controls the piston rod II to return to the original position.
The utility model discloses a high accuracy hydrovalve leakage measurement system compares with prior art and has following advantage:
the utility model discloses a measurement system simple structure easily builds, and it is fast to reset after the piston rod removes, and control is accurate, and the survey is simple quick, but serialization test multiunit test piece, and measurement accuracy is high, adopts the displacement sensor that the precision is 0.01mm, can reach 0.05mL/min to the measurement accuracy who lets out leakage quantity.
