Abstract

The present invention relates to a kind of outflow safety valve device for testing functions, including vacuum pump, altimeter, first row air valve, the first shut-off valve, the second shut-off valve, third shut-off valve, calibrator, differential pressure indicator, height limiter, metering valve and second row air valve, the second shut-off valve and calibrator are sequentially installed on the main pipeline between the vacuum pump and altimeter.The invention has the advantages that being provided with first exhaust valve connector and second exhaust valve connector, two valve can be tested simultaneously, improve testing efficiency, structure is simple, easy to use.

Description

Outflow safety valve device for testing functions
Technical field
The present invention relates to a kind of outflow safety valve device for testing functions.
Background technique
Safety valve carries out functional test by simulation ambient pressure, to outflow safety valve, meets needed for functional test It is required that but the drawback present in it are as follows: at high cost, the period is long and difficult in maintenance, and test process is comparatively laborious, test effect Rate is low.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of outflow safety valve device for testing functions, of the invention Technical solution is:
Outflow safety valve device for testing functions, including vacuum pump, altimeter, first row air valve, the first shut-off valve, second Shut-off valve, third shut-off valve, calibrator, differential pressure indicator, height limiter, metering valve and second row air valve, in the vacuum pump The second shut-off valve and calibrator are sequentially installed on main pipeline between altimeter, the supervisor between altimeter and calibrator It is communicated with the first branch pipe(tube) on road, is sequentially installed with differential pressure indicator and height limiter on first branch pipe(tube), close to highly Regulating valve is installed on the first branch pipe(tube) at table;Second is communicated on main pipeline between vacuum pump and the second shut-off valve Pipeline is sequentially installed with the first vacuum meter and the first shut-off valve on second branch pipe(tube), in first vacuum meter and first section Only be provided with third branch pipe(tube) on the second branch pipe(tube) between valve, be disposed on the third branch pipe(tube) first row air valve and First exhaust valve connector;It further include the 4th branch pipe(tube), one end of the 4th branch pipe(tube) is connected to vacuum pump and the second cut-off On main pipeline between valve, the other end is equipped with second exhaust valve connector, and is sequentially installed on the 4th branch pipe(tube) Three shut-off valves, metering valve, the second vacuum meter and second row air valve.
The invention has the advantages that it is provided with first exhaust valve connector and second exhaust valve connector, it can be simultaneously Two valve are tested, testing efficiency is improved, structure is simple, easy to use.
Detailed description of the invention
Fig. 1 is agent structure schematic diagram of the invention.
Specific embodiment
The invention will now be further described with reference to specific embodiments, the advantages and features of the present invention will be with description and It is apparent.But examples are merely exemplary for these, and it is not intended to limit the scope of the present invention in any way.Those skilled in the art Member it should be understood that without departing from the spirit and scope of the invention can details to technical solution of the present invention and form into Row modifications or substitutions, but these modifications and replacement are fallen within the protection scope of the present invention.
Referring to Fig. 1, the present invention relates to a kind of outflow safety valve device for testing functions, including vacuum pump 1, altimeter 2, One exhaust valve 15, the first shut-off valve 13, the second shut-off valve 7, third shut-off valve 8, calibrator 6, differential pressure indicator 5, height limiter 4, Metering valve 9 and second row air valve 11 are sequentially installed with second section on the main pipeline between the vacuum pump 1 and altimeter 2 Only valve 7 and calibrator 6 are communicated with the first branch pipe(tube) on the main pipeline between altimeter 2 and calibrator 6, in first branch pipe It is sequentially installed with differential pressure indicator 5 and height limiter 4 on road, regulating valve is installed on the first branch pipe(tube) close at altimeter 2 3;It is communicated with the second branch pipe(tube) on main pipeline between vacuum pump 1 and the second shut-off valve 7, is successively pacified on second branch pipe(tube) The second branch pipe(tube) equipped with the first vacuum meter 14 and the first shut-off valve 13, between first vacuum meter and 14 first shut-off valves 13 On be provided with third branch pipe(tube), first row air valve 15 and first exhaust valve connector are sequentially installed on the third branch pipe(tube) 16;It further include the 4th branch pipe(tube), one end of the 4th branch pipe(tube) is connected to the main pipeline between vacuum pump 1 and the second shut-off valve 7 On, the other end is provided with second exhaust valve connector 12, and third shut-off valve 8, meter are sequentially installed on the 4th branch pipe(tube) Measure valve 9, the second vacuum meter 10 and second row air valve 11.
The working principle of the invention is: providing gas source by vacuum pump, is divided to two branches (third branch pipe(tube) and the 4th branch pipe Road) after, two valve connectors are formed, realize the test to valve.
