Abstract
The invention provides a valve leakage test device, which comprises a valve body, a valve plate and a pressure test plate, wherein a seal pad is arranged between the valve body and the pressure test plate; the pressure test plate is connected with a large water inlet pipe, a small water inlet pipe and a pressure meter which are communicated with an inner cavity of the valve body respectively; the large water inlet pipe is connected with the small water inlet pipe through a three-way joint, and the other end of the three-way joint is connected with the water inlet pipe; a block valve is arranged on the large water inlet pipe; and an adjusting valve and a micro flow meter are arranged on the small water inlet pipe sequentially. The valve leakage test device has the advantages of simple structure, quantitative detection of the amount of valve leakage, and convenient and quick test.
Description
Technical field
The present invention relates to a kind of device, particularly relate to a kind of valve leakage test device.
Background technology
During valve seal test at present, adopt an end to seal with the pressure testing plate, valve is in the closed position, suppress to authorised pressure pressurize a period of time, watch the valve sealing face place to have or not leakage with eyes, can only judge qualitatively whether valve leaks, and can not quantitatively measure the size of valve leak amount.
Summary of the invention
Can only to judge whether valve leaks in order overcoming qualitatively when existing valve seal is tested, and can not quantitatively to measure the deficiency of leakage rate size, the invention provides a kind of valve leakage test device.
The technical solution adopted for the present invention to solve the technical problems is a kind of valve leakage test device, comprise valve body, valve plate and pressure testing plate, between valve body and the pressure testing plate sealing gasket is housed, is connected to big water inlet pipe, little water inlet pipe and tensimeter on the pressure testing plate, communicate with body cavity respectively; Be connected by three-way connection between big water inlet pipe and the little water inlet pipe, the other end of three-way connection links to each other with water inlet pipe; On big water inlet pipe, block valve is housed, variable valve and micro flowmeter are housed on little water inlet pipe successively.
The invention has the beneficial effects as follows simple in structurely, can quantitatively measure the size of valve leak amount, convenient test is quick.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural map of present embodiment;
Among the figure: 1. valve body; 2. valve plate; 3. sealing gasket; 4. pressure testing plate; 5. tensimeter; 6. big water inlet pipe; 7. variable valve; 8. little water inlet pipe; 9. block valve; 10. micro flowmeter; 11. three-way connection; 12. water inlet pipe.
Embodiment
As shown in Figure 1, a kind of valve leakage test device comprises valve body 1, valve plate 2 and pressure testing plate 4, between valve body 1 and the pressure testing plate 4 sealing gasket 3 is housed, and is connected to big water inlet pipe 6, little water inlet pipe 8 and tensimeter 5 on the pressure testing plate 4, communicates with valve body 1 inner chamber respectively; Be connected by three-way connection 11 between big water inlet pipe 6 and the little water inlet pipe 8, the other end of three-way connection 11 links to each other with water inlet pipe 12; On big water inlet pipe 6, block valve 9 is housed, variable valve 7 and micro flowmeter 10 are housed on little water inlet pipe 8 successively.During concrete leakage test, pressure testing plate 4 is connected with valve body 1, valve plate 2 is in the closed position, close variable valve 7, block valve 9 is in opening, and press water enters from water inlet pipe 12, enter in the valve body 1 through three-way connection 11, big water inlet pipe 6, block valve 9, at first get rid of air in the valve body 1, valve body 1 internal pressure slowly is raised to the test pressure value of regulation, can read from tensimeter 5; Close block valve 9 then, because the seepage between the sealing surface, the drop of tensimeter 5 upward pressures, open variable valve 7 this moment, and fine setting, press water enters in the valve body 1 from little water inlet pipe 8, micro flowmeter 10, variable valve 7, keeps steady state value (test pressure of regulation) until tensimeter 5, read the reading of micro flowmeter 10 this moment, is the leakage that this is tested valve.
Claims (1)
1. a valve leakage test device comprises valve body, valve plate and pressure testing plate, between valve body and the pressure testing plate sealing gasket is housed, and it is characterized in that: be connected to big water inlet pipe, little water inlet pipe and tensimeter on the described pressure testing plate, communicate with body cavity respectively; Be connected by three-way connection between big water inlet pipe and the little water inlet pipe, the other end of three-way connection links to each other with water inlet pipe; On big water inlet pipe, block valve is housed, variable valve and micro flowmeter are housed on little water inlet pipe successively.
