Description
Technical field
This utility model relates to calibration equipment, especially relates to a kind of calibration equipment of relief valve on pressure vessels and pipes.
Background technology
Relief valve is the safety attachment of pressure vessel and pipe-line equipment; its Reliability of Microprocessor and performance quality are directly connected to equipment and the safety of the person; and be closely related with energy-conservation and environmental conservation; safety valve pressure is adjusted and too high can not be opened in time when occurring dangerous; easily cause the generation pressure setting of accident too low to arise that race, the phenomenon such as emit; waste the energy and pollute environment, the most also frequently the sealing surface of relief valve can be caused damage because of take-off.The set-pressure of relief valve be related to equipment pressurized too high time the important parameter that whether can open in time of relief valve, the relevant regulations according to country must periodic detection set-pressure to relief valve.
Traditional detection check method mainly uses off-line verification, first relief valve is disassembled above equipment, then on safety valve checkout platform, carry out verification detection, this method operation complexity, workload is big, and the time is long, sometimes dismounting relief valve also affects normal production, and easily the medium in pipe line is let out in air, and pollute environment, bring personnel to injure；The most this detection typically requires external power supply.
At present, document is also mentioned some on-line testing devices, but these devices all exist following deficiency: be 1, containing inessential parts, the lightest；2, detection body non-integration, is not easy to on-the-spot Fast Installation and completes verification；3, when verification distant place or eminence equipment, need to move calibration equipment everywhere, be not easy to work and carry out；4, when relief valve to be verified and calibration equipment body too far time, be unfavorable for that the saving of cylinder gas uses, have certain limitation, it is impossible to meet the relief valve detection of Multiple Type and different size.
Summary of the invention
For the problems referred to above, this utility model provides a kind of has testing device of safety valve that is light portable, easy and simple to handle, safe and reliable without additional power source, equipment and that can meet Multiple Type relief valve.
This utility model be the technical scheme is that by its technical problem of solution
Portable safety valve calibration equipment, including source of the gas and inspection body, it is characterized in that: be connected by the first pipeline between described source of the gas with inspection body, described inspection body is connected with equipment with pressure by second pipe, described equipment with pressure is connected with relief valve by the second stop valve, connects and is provided with bleeder valve on the second pipe of described second stop valve and relief valve junction.
Wherein, described inspection body includes that regulation valve, Pressure gauge and the three-way valve being successively set on main pipeline, described regulation valve and the first pipeline are connected, and described three-way valve is connected with second pipe.
As the further improvement of such scheme, described Pressure gauge is provided with 2.
As the further improvement of such scheme, described first, second pipeline is high-pressure hose.
As the further improvement of such scheme, one end that described first, second pipeline is connected with inspection body is respectively arranged with articulation.
Further, described source of the gas includes gas cylinder and the first stop valve being sequentially connected with gas cylinder and air relief valve.
The beneficial effects of the utility model are: compared with traditional calibration equipment, this appliance arrangement light portable, easy and simple to handle, can meet Multiple Type relief valve detection, safe and reliable.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model rather than whole embodiment, and those skilled in the art is not on the premise of paying creative work, it is also possible to other designs obtained according to these accompanying drawings and accompanying drawing:
Fig. 1 is the control schematic diagram of this utility model preferred embodiment.
Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to be completely understood by the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art is obtained on the premise of not paying creative work, belong to the scope of this utility model protection.
With reference to Fig. 1, the Portable safety valve calibration equipment of this utility model preferred embodiment, Portable safety valve calibration equipment, including source of the gas 1, inspection body 2, it is characterized in that: be connected by the first pipeline 6 between described source of the gas 1 with inspection body 2, described inspection body 2 is connected with equipment 3 with pressure by second pipe 7, and described equipment 3 with pressure is connected with relief valve 4 by the second stop valve 5, connects and is provided with on the second pipe of described second stop valve 5 and relief valve 4 junctionBleeder valve8；Wherein, described inspection body includes regulation valve 21, Pressure gauge 22 and the three-way valve 23 being successively set on main pipeline, described regulation valve and the first pipeline 6 are connected, described three-way valve 23 is connected with second pipe 7, described regulation valve 21, can be used for regulating bleed pressure, and can a upper gas cylinder air pressure drop be as little as unsatisfactory for verification require time, close this valve, this valve downstream air pressure can be kept, after gas cylinder to be updated, proceed verifying work；Described three-way valve 23 is connection source of the gas and device to be verified when verification, before verification, rotates this valve, the gas of pipeline remaining between stop valve 5 and bleeder valve 8 of releasing；After verification, rotate this valve, this valve downstream gas is vented via this valve, it is ensured that downstream line is dismounting and in moving process without press operation, it is ensured that safety；23 connect emptying flexible pipe 24, it is ensured that gas of releasing is emitted at away from operator.
