Abstract
The invention provides a closed valve service life test device which comprises a tested 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 the tested valve are successively connected after the liquid storage tank. The cut-off valves B are connected after the tested valve. The components above 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, and the bottom of the water tank is connected with the water pump through a water pipe. The test device has the advantages that when a service life test is carried out, an on-line seal test can be carried out; time saving and labor saving effects are achieved; test is convenient and quick; the machine has dual functions; gas and liquid test mediums can be switched; the cost is low; and the application is wide.
Description
Technical field
The present invention relates to a kind of proving installation, particularly relate to a kind of multifunctional airtight valve life test apparatus.
Background technology
Current airtight valve is when carrying out band and carrying durability test, when proceeding to stipulated number, when sealing property detection is carried out to tested valve, tested valve need be pulled down from testing conduit, separately leakage test be carried out to tested valve, more tested valve be installed on testing conduit after having tested, waste time and energy, testing crew labour intensity is large, and need build different test loops for different gas and liquid pilot medium in addition, cost is high.
Summary of the invention
Waste time and energy when carrying out durability test to overcome existing airtight valve, testing crew labour intensity is large, and builds different test loops for dissimilar medium, the deficiency that cost is high, the invention provides a kind of airtight valve life test apparatus.
The technical solution adopted for the present invention to solve the technical problems is a kind of airtight valve life test apparatus, comprise tested valve, water pump, fluid reservoir, pressure regulator valve, stop valve A and stop valve B, water pump is connected with fluid reservoir, pressure regulator valve is connected to successively after fluid reservoir, stop valve A, pressure transducer and tested valve, stop valve B is also connected to after tested valve, connected by pipeline between above-mentioned each parts, stop valve C and leakage rate measuring tool are also housed after tested valve, also a pipeline is separately connected to before pressure transducer, be connected to stop valve A successively, pressure regulator valve, gas-holder and air compressor machine, also a pipeline is separately connected to after tested valve, be connected to stop valve B successively, water tank, water tank bottom is connected by water pipe with water pump.
Beneficial effect of the present invention can carry out leakage test online when carrying out durability test, time saving and energy saving, and convenient test is quick, a machine dual-purpose, gas and liquid pilot medium changeable, cost is low, and application is wide.

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, pressure regulator valve 3 is connected to successively after fluid reservoir 11, stop valve A4, pressure transducer 5 and tested valve 6, stop valve B9 is also connected to after tested valve 6, connected by pipeline between above-mentioned each parts, stop valve C7 and leakage rate measuring tool 8 are also housed after tested valve 6, also a pipeline is separately connected to before pressure transducer 5, be connected to stop valve A4 successively, pressure regulator valve 3, gas-holder 2 and air compressor machine 1, also a pipeline is separately connected to after tested valve 6, be connected to stop valve B9 successively, water tank 12, be connected by water pipe with water pump 10 bottom water tank 12.
Time initial, gas-holder 2 or fluid reservoir 11 are full of medium, and the top hole pressure of setting pressure regulator valve 3 is 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, be full of after system until water, confirm in removal system after air, close stop valve B9 again), system is boosted, until pressure transducer 5 send pressure reach setting value time, send signal, tested valve 6 cuts out automatically, tested valve 6 cuts out to put in place and sends pass and put in place after signal, stop valve A4 closes automatically, stop valve B9 opens automatically simultaneously, medium after the tested valve valve of emptying, after the delay adjustments time, tested valve 6 is opened automatically, complete a circulation.Repetition above-mentioned steps like this, realizes durability test function.
Leakage test: when after durability test to certain (setting adjustable) number of times, leakage test can be carried out online.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, opens stop valve A4, when system boosts to the seal test pressure of setting, opens stop valve C7, the bubble number within the dwell time in dosing leak amount detection tool 8 or gas volume.
