Background technology
Safety valve is the safety attachment of pressure vessel and pipe-line equipment, its Reliability of Microprocessor and the fine or not direct relation of performance
It is closely related to equipment and the safety of the person, and with energy-conservation and environmental protection, safety valve pressure is adjusted too high when occurring dangerous
Can not open in time, easily cause accident generation pressure setting it is too low the phenomenon such as race just occurs, emits, waste the energy and pollution
Environment, sometimes can also because of take-off frequently to the sealing surface of safety valve caused by damage.The set-pressure of safety valve is to be related to set
Enjoy when pressing through high safety valve whether the important parameter that can be opened in time, must be regular to safety valve according to the relevant regulations of country
Detect set-pressure.
Traditional detection check method is mainly using offline verification, i.e., under being dismantled first above safety valve slave unit
Come, verification detection is then carried out on safety valve checkout platform, this method complex operation, workload is big, and the time is long, sometimes tears open
Unload safety valve and also affect normal production, and easily the medium in pipe line is let out in air, and environment is polluted, band messenger
Member's injury；In addition this detection usually requires external power supply.
Utility model content
In view of this, the utility model embodiment provides a kind of safety valve on-line testing device, main purpose be solve by
In safety valve installation and the limitation of use condition, dismounting, lifting and the installation of safety valve are more difficult, and workload is big, verifies into
This height, the problem of check-verifying period is long.
The utility model is realized by the following technical solutions：
A kind of online safety valve testing system, including source of the gas body, inspection body, the body to be tested being sequentially connected with, its
In：
Source of the gas body, for providing required air pressure during verification, the source of the gas body includes gas cylinder, the booster pump being sequentially connected with
And check valve；Verify body, measure during for safety valve testing, including pressure regulator valve, at least two pressure being sequentially connected with
Relief valve is connected with table, a triple valve, the bypass of the triple valve；Body to be tested, including the first stop valve, are connected to
The flange seal terminal pad of one stop valve tract, flange seal terminal pad middle cylinder is provided with connector, flange seal connection
The side flange face of disk is sequentially connected with the second stop valve and pressure body, and opposite side flange face is sequentially connected with safety valve and the 3rd cut-off
Valve.
Further, the check valve is unidirectional stop valve, the dual-use function with check valve and stop valve.
Further, the source of the gas body and examine between body, examine and be connected with high pressure between body and body to be tested
Flexible pipe, the high-pressure hose is provided with snap joint with the source of the gas body, inspection body, body junction to be tested.
By adopting the above-described technical solution, compared with prior art, the utility model safety valve on-line testing device is light
Ingeniously, it is easy to movement, without dismantling safety valve during verification, verification cost is low, the cycle is short, the pressure after safety valve setting after verification
Adjustment accesses guarantee with sealing property, extends the service life of safety valve.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
