Abstract

The utility model provides a closed valve service life test device which comprises a test valve, a water pump, a liquid storage tank, pressure regulating valves, cut-off valves A and cut-off valves B. The water pump is connected with the liquid storage tank. The pressure regulating valves, the cut-off valves A, a pressure sensor and a tested valve are successively connected after the liquid storage tank. The cut-off valves B are connected after the tested valve. The components are connected through pipelines. A cut-off valve C and a leakage rate measurement tool are arranged after the tested valve. A pipeline is connected before the pressure sensor, wherein the pipeline is successively connected with the cut-off valves A, the pressure regulating valves, a gas storage tank and an air compressor. Another pipeline is connected after the tested valve, wherein the pipeline is successively connected with the cut-off valves B and a water tank. The bottom of the water tank is connected with the water pump through a water pipe. The device provided by the utility model has the advantages that when a service life test is carried out, an on-line seal test can be carried out; the closed valve service life test device has the advantages of time saving, labor saving, convenient and quick test, low cost and wide application; the machine has two functions; and gas and liquid test mediums are exchangeable.

Description

A kind of airtight valve life test apparatus
Technical field
The utility model relates to a kind of proving installation, particularly relates to a kind of multifunctional airtight valve life test apparatus.
Background technology
At present airtight valve is when be with year durability test, when proceeding to stipulated number, when tested valve is carried out to sealing property detection, tested valve need be pulled down from testing conduit, separately tested valve be carried out to leakage test, after having tested, more tested valve be installed on testing conduit, waste time and energy, testing crew labour intensity is large, need build different test loops in addition for different gas and liquid pilot medium, and cost is high.
Summary of the invention
In order to overcome existing airtight valve, when carrying out durability test, waste time and energy, testing crew labour intensity is large, and builds different test loops for dissimilar medium, the deficiency that cost is high, and the utility model provides a kind of airtight valve life test apparatus.
It is a kind of airtight valve life test apparatus that the utility model solves the technical scheme that its technical matters adopts, comprise tested valve, water pump, fluid reservoir, pressure regulator valve, stop valve A and stop valve B, water pump is connected with fluid reservoir, after fluid reservoir, be connected to successively pressure regulator valve, stop valve A, pressure transducer and tested valve, after tested valve, be also connected to stop valve B, between above-mentioned each parts, by pipeline, connect, stop valve C and leakage rate measuring tool are also housed after tested valve, before pressure transducer, be also separately connected to a pipeline, be connected to successively stop valve A, pressure regulator valve, gas-holder and air compressor machine, after tested valve, be also separately connected to a pipeline, be connected to successively stop valve B, water tank, water tank bottom is connected by water pipe with water pump.
The beneficial effects of the utility model can be carried out online leakage test when carrying out durability test, and time saving and energy saving, convenient test is quick, a machine dual-purpose, and gas and liquid pilot medium are changeable, and cost is low, and application is wide.
Accompanying drawing explanation
Fig. 1 is the structural map of the present embodiment;
In figure: 1. air compressor machine; 2. gas-holder; 3. pressure regulator valve; 4. stop valve A; 5. pressure transducer; 6. tested valve; 7. stop valve C; 8. leakage rate measuring tool; 9. stop valve B; 10. water pump; 11. fluid reservoirs; 12. water tanks.
Embodiment
As shown in Figure 1, a kind of airtight valve life test apparatus, comprise tested valve 6, water pump 10, fluid reservoir 11, pressure regulator valve 3, stop valve A4 and stop valve B9, water pump 10 is connected with fluid reservoir 11, after fluid reservoir 11, be connected to successively pressure regulator valve 3, stop valve A4, pressure transducer 5 and tested valve 6, after tested valve 6, be also connected to stop valve B9, between above-mentioned each parts, by pipeline, connect, stop valve C7 and leakage rate measuring tool 8 are also housed after tested valve 6, before pressure transducer 5, be also separately connected to a pipeline, be connected to successively stop valve A4, pressure regulator valve 3, gas-holder 2 and air compressor machine 1, after tested valve 6, be also separately connected to a pipeline, be connected to successively stop valve B9, water tank 12, water tank 12 bottoms are connected by water pipe with water pump 10.
When initial, gas-holder 2 or fluid reservoir 11 are full of medium, set the top hole pressure of pressure regulator valve 3 to test pressure, and stop valve A4, stop valve C7 are in closed condition; Tested valve 6, stop valve B9 are in opening.
Durability test: open stop valve A4, for gas test medium, close stop valve B9 (for water test medium simultaneously, after water is full of system, confirm in removal system after air, close again stop valve B9), system is boosted, when pressure transducer 5 sends pressure and reaches setting value, send signal, tested valve 6 cuts out automatically, tested valve 6 cuts out to put in place to send to close and puts in place after signal, stop valve A4 closes automatically, stop valve B9 opens automatically simultaneously, medium after the tested valve valve of emptying, delay adjustments is after the time, tested valve 6 is opened automatically, complete a circulation.So repeat above-mentioned steps, realize durability test function.
Leakage test: when durability test is to certain (setting adjustable) number of times, can carry out online leakage test.Before test: stop valve A4, stop valve C7 are in closed condition; Tested valve 6, stop valve B9 are in opening; Leakage test: close tested valve 6, open stop valve A4, when system boosts to the seal test pressure of setting, open stop valve C7, measure leakage rate and detect bubble number or the gas volume in tool 8 within the dwell time.
