Abstract
The utility model discloses a device for testing the life span of a valve, consisting of a pressure reserveir and a blankoff flange with a ring flange connected with the pressure reserveir through a pipeline. A start-and-stop valve and a pressure sensor are arranged in turn from the pressure reserveir to the blankoff flange on the pipeline. When a testing is conducted, water in the pressure reserveir is boosted to and maintained between 150 to 250 percent of the rated pressure in time of testing the valve by a pressure pump, the valve cavity of a to-be-tested valve is connected with the flange seal of the blankoff flange, the valve to be tested is put into water, and a start-and-stop valve is turned on, and pressure water is poured into the valve cavity of the to-be-tested valve. When water in the valve cavity reaches the setting value, the pressure retainer of the start-and-stop valve is turned off to observe whether the pressure loss displayed on the pressure sensor is overproof. When the pressure is not overproof, the valve to be tested proves to be well sealed. After the pressure is released, the to-be-tested valve is turned on and off without pressure for a plurality of times. The process is repeated and recorded until an overproof leakage occurs to the to-be-tested valve, thereby achieving an automatic and continuous testing of the life span of a valve.
Description
Technical field:
The utility model relates to a kind of proving installation, relates to a kind of valve life testing device specifically.
Background technology:
Valve valve plate and valve seat in opening-closing process produce wearing and tearing inevitably, and after repeatedly opening and closing, when wearing and tearing between valve plate, the valve seat acquire a certain degree, the leakage phenomenon that exceeds standard will appear in valve after closing.A collection of valve is produced, and how long is its serviceable life? also promptly after opening and closing how many times, occur leaking exceeding standard? also there is not a kind of ideal device to test at present to it.
The utility model content:
The purpose of this utility model just is to provide a kind of valve life testing device.
The purpose of the utility model is achieved in that
It comprises pressure reserveir, the blind plate that has mounting flange that is connected with described pressure reserveir by pipeline; On described pipeline, be disposed with keying valve, pressure transducer from pressure reserveir to blind plate.
Impulsive force during for the buffering pressurization, described pressure reserveir and the pipeline that opens and closes between the valve are provided with reduction valve.
For realizing automatic control, described keying valve is a solenoid valve, and the execution coil of described solenoid valve is electrically connected with the output port of microprocessor; The signal output part of pressure transducer is electrically connected with the input port of described microprocessor.
Advantage of the present utility model just is to be provided with a pressure reserveir, the blind plate that has mounting flange that is connected with this pressure reserveir by pipeline, and on described pipeline, be disposed with from pressure reserveir to blind plate and open and close valve, pressure transducer.During test, the 150-250% of rated pressure and keep this pressure when at first the water in the pressure reserveir being boosted to valves test with force (forcing) pump, with after treating the valve pocket of side valve door and flangeseal on the described blind plate being connected, to treat that the side valve door places water, open and open and close valve injection pressure water in the valve pocket for the treatment of the side valve door, when the hydraulic pressure in the valve pocket reaches setting value, close and open and close valve pressurize timing, whether the shown pressure value of observed pressure sensor has loss, if then showing, the pressure free of losses treats that the side valve door sealing is good, to treat after the pressure release that the side valve door opens and closes repeatedly, repeat said process, and record valve opening and closing number of times up to treating the side valve door bad seals to occur till, thereby realize to the valve test in serviceable life, for the user provides objective operating life data.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in the figure, the utility model comprises pressure reserveir 1, the blind plate that has mounting flange 34 that is connected with described pressure reserveir 1 by pipeline 2; On described pipeline 2, be disposed with keying valve 5, pressure transducer 6 from pressure reserveir 1 to blind plate 4.Impulsive force during for the buffering pressurization, described pressure reserveir 1 and the pipeline 1 that opens and closes between the valve 5 are provided with reduction valve 7.For realizing automatic control, described keying valve 5 is elected solenoid valve as; The execution coil of solenoid valve is electrically connected with the output port of microprocessor 8; The signal output part of pressure transducer 6 is electrically connected with the input port of described microprocessor 8.
