Specific embodiment
Below the present invention is further described the embodiment combined in accompanying drawing：
As shown in Figure 1 and 2, the invention mainly comprises safety valve exhaust port 1, closure plate component, collection fistulae 7, flow tester 9, data
Acquisition Processor 10, computer 11, database 12 and printer 13.
Connect closure plate component in safety valve exhaust port 1, as shown in Fig. 2 closure plate component includes cover plate 4, sealing gasket 3, elasticity
Tightening piece 2, supporter 6 and snap joint 5.The outer surface of supporter 6 connects sealing gasket 3 and elastic tensioning block 2, elastic tensioning block 2
Setting is distributed about 3 with sealing gasket.
The supporter 6 is cylindrical structure, is made using lightweight, the preferable material of intensity, for example：Lucite or aluminium
Alloy.Supporter 6 primarily serves supporting role.
Supporter 6 and the common connecting cover plate 4 of the lower surface of sealing gasket 3, the connection snap joint 5 of the center of cover plate 4.
The sealing gasket 3 is made using elastomeric soft rubber material, and sealing gasket 3 is towards the side table of elastic tensioning block 2
Face is provided with the reservoir 14 of at least two annulars, and the cross section of reservoir 14 is V-arrangement.Reservoir 14 is used to store expanding foam solution
Body.
The cover plate 4 is made using lightweight transparent material, for example：Lucite.Because cover plate 4 employs lightweight transparent material
Material makes, and making the operation of safety valve leakage test becomes easier, easy, can improve the work effect of safety valve leakage test
Rate.Meanwhile, once the gas of safety valve escape spills from the other sealing surfaces of conduit, can quicklook observe, so as to protect
The accuracy of card test data.
The elastic tensioning block 2 is made using elastomeric material, for example：Rubber.Elastic tensioning block 2 fills in safety valve exhaust port
1, by elasticity and frictional force sealing gasket is made against the flange sealing surface of safety valve exhaust port 1 or the outer surface of screw thread exhaust outlet.
The snap joint 5 can quickly connect collection fistulae 7 and keep sealing not leak, and collect the gas that the pipe of fistulae 7 will leak out out
Body medium is derived and determines its leakage rate.
Collection fistulae 7 one end connects the snap joint 5 of closure plate component, the flow tester of other end connection traffic tester 9
Fast interface 8.Flow tester 9 is electrically connected with data collection processor 10, and data collection processor 10 is electrically connected with computer 11,
Computer 11 is electrically connected with database 12 and printer 13.
The present invention operation principle be：Foaming liquid is applied in the reservoir on sealing gasket first, by elastic expanding
Tight block is filled in safety valve exhaust port, makes the sealing gasket for having smeared foaming liquid touch safety valve exhaust port flange sealing surface or spiral shell
The outer surface of line safety valve exhaust port.Because safety valve escape amount very little, and the gas for leaking out are exported, therefore by elastic expanding
The frictional force that the elasticity of tight block is produced can provide enough sealing preload pressures.Then, one end insertion of collection fistulae is quickly connect
In head, other end insertion flow tester fast interface.Then, flow tester signal output part is accessed at data acquisition
Reason device, data collection processor, printer are electrically connected with computer；Computer passes through network and database（Server）Carry out data friendship
Change, computer is first by the numbering of valve to be tested and essential information write into Databasce（Server）, then by test data, data and curves with
Test result writes, and can inquire about the test data of all valves by computer, it is ensured that the situation of each test assignment can be entered
Row is reviewed.
Before test, computer is first by the numbering of tape test safety valve and essential information write into Databasce（Server）, or from number
According to storehouse（Server）In transfer the essential information of safety valve to be tested, distribute new inspection numbering；Preparation before test is just
Position after, the pressure of safety valve entrance is risen into seal test pressure and pressure remained steady is made, start flow tester and
Data collection processor, and open the TT＆C software in computer；TT＆C software will measure flow tester in process of the test
Real-time traffic data or when m- flow curve be displayed on screen, and the flow value automatic data collection of a minute in the stipulated time,
Show and record, then according to GB/T12243-2005《Spring loaded safe valve》Automatically the sealing of safety valve is judged
Whether performance is up to standard；All test datas, data and curves and test result are synchronously written database（Server）In, by surveying
Examination management software can be inquired about, and automatically generate test report and test record, obtained and imported leakage test data and result
In the verification report and calibration tails of safety valve.
The present invention not only makes the seal test device of safety valve become simpler and easy to operate, and work can be greatly improved
Make efficiency；Simultaneously as it makes sealing property test realize digitize, test data and result realize record automatically and certainly
Dynamic storage, eliminates manual read and fetches data the error being likely to result in, and makes measuring accuracy and stability also obtain large increase again.
