Abstract
One kind not closing safety valve seal test device, for not closing safety valve leakage test, composition includes: seal closure, the anti-flange in outlet, pressure gauge, measuring cup, vacuumfilter, air accumulator, reservoir, ball valve 1, ball valve 2, ball valve 3, several connecting pipe roads, metering liquid；Seal closure is connect with safety valve spring cover, is exported anti-flange and is connect with safe valve outlet, is ball valve 1 between seal closure and air accumulator, is ball valve 2 between pressure gauge and measuring cup, is ball valve 3 between vacuumfilter and measuring cup.This device solves the problems, such as traditional not close safety valve seal test device test result inaccuracy.
Description
Technical field
It is that one kind does not close safety valve leakage test the utility model relates to not close safety valve sealing performance detection field
Device.
Background technique
Safety valve (hereinafter referred to as " safety valve ") is not closed and is widely used in thermoelectricity system, and such structure safety valve is let out
Leakage, a part of gas medium are discharged by safety valve exiting exhaust gas mouth, and also some gas medium is between valve deck and valve rod
Gap discharge, the gas medium leaked out between valve deck and valve rod is by safety valve spring cover to atmosphere.
The method of traditional safety valve leakage test is to install anti-flange in the outlet of safety valve, connects gas collecting tube and amount
Cup, clock the number of bubbles for checking and revealing per minute, then leakage number of bubbles is compared with the slip that standard maximum allows, and sentences
Whether the leakproofness of Dingan County's full valve is qualified.The test method can only detect the gas revealed by safety valve exiting exhaust gas mouth,
Leaked gas between valve deck and valve rod cannot be collected.
Summary of the invention
The purpose of this utility model is to provide one kind not to close safety valve seal test device, which can be quasi-
True tests the sealing performance of safety valve, improves the accuracy of test result.
The technical solution of the utility model is:
One kind not closing safety valve seal test device, it includes seal closure, the anti-flange in outlet, pressure gauge, measuring cup, vacuum
Nutsch filter, air accumulator, reservoir, ball valve 1, ball valve 2, ball valve 3, several connecting pipe roads, metering liquid, seal closure and safety
The connection of valve spring cover, exports anti-flange and connect with safe valve outlet, is ball valve 1, pressure gauge and amount between seal closure and air accumulator
It is ball valve 2 between cup, is ball valve 3 between vacuumfilter and measuring cup.
Further, seal closure is made of lightweight transparent material.
The beneficial effects of the utility model are: one kind does not close safety valve seal test device and is capable of detecting when to pass through safety
Leaked gas total amount between the gas and valve deck and valve rod of the leakage of valve outlet exhaust outlet.
Detailed description of the invention
Fig. 1 is that one kind does not close safety valve seal test device schematic diagram
In figure, 5. seal closures, 6. ball valves 1,7. air accumulators, 8. vacuumfilters, 9. ball valves 3,10. measuring cups, 11. meterings are used
Liquid, 12. reservoirs, 13. ball valves 2,14. pressure gauges, the 15. anti-flanges in outlet
Specific embodiment
Embodiment shown in Fig. 1, a kind of application method for not closing safety valve seal test device, including following step
It is rapid:
1) safety valve to be detected is not closed safety valve seal test device with one kind to connect, it is ensured that any connection interface
There must not be leakage；
2) ball valve 1 (6) are closed, closed air accumulator (7), opened ball valve 2 (13), opened ball valve 3 (9), open vacuum filtration
Device (8), the interior metering of measuring cup (10) rise to graduation mark V1 with liquid (11) liquid level line；
4) ball valve 3 (9) are closed, closed vacuumfilter (8), opened air accumulator (7), opened ball valve 1 (6), discharge connection
With metering liquid (11) all in pipeline, guarantee that the registration of pressure gauge (14) is no more than amount by the aperture of regulation ball valve 1 (6)
Journey；
5) ball valve 1 (6) are closed, closed air accumulator (7)；
6) pressure of safety valve import to be detected is risen into seal test pressure, closes ball valve 2 (13) after one minute, record
Metering liquid (11) liquid level line scale V2 in measuring cup (10)；
7) the leakage rate V3=V2-V1 of safety valve is calculated.
Claims (2)
1. one kind does not close safety valve seal test device, it is characterised in that: it include seal closure (5), the anti-flange (15) in outlet,
Pressure gauge (14), measuring cup (10), vacuumfilter (8), air accumulator (7), reservoir (12), ball valve 1 (6), ball valve 2 (13), ball
Liquid (11) are used in valve 3 (9), several connecting pipe roads, metering, and seal closure (5) is connect with safety valve spring cover, export anti-flange
(15) it is connect with safe valve outlet, is ball valve 1 (6) between seal closure (5) and air accumulator (7), pressure gauge (14) and measuring cup (10)
Between be ball valve 2 (13), between vacuumfilter (8) and measuring cup (10) be ball valve 3 (9).
2. one kind according to claim 1 does not close safety valve seal test device, it is characterised in that: the seal closure
