Abstract
The utility model discloses a pressure vessel relief valve verifying attachment, including the relief valve body, the relief valve body includes main valve and sealed chamber, and the relief valve body outside is provided with a pressure sensor, and relief valve body inboard is provided with the 2nd pressure sensor, and sealed intracavity is provided with alarm, control chip, memory, LED display screen, power and display screen button, and the power links to each other with alarm, LED display screen, control chip and memory respectively, and a pressure sensor and the 2nd pressure sensor all connect with control chip, the utility model discloses a relief valve pressure verifying attachment sets up on the relief valve, and is permanent effective, can detect the set pressure of relief valve at any time, and the in -process of adjusting moreover need not dismantled the relief valve, and the setting value is automatic when unqualified to send the alarm tone detecting, has safe and reliable's advantage.
Description
Technical field
The utility model relates to a kind of pressure vessel relief valve verifying attachment.
Background technology
Safety valve is the safety attachment of boiler, pressure vessel and pipe-line equipment, its Reliability of Microprocessor and performance quality are directly connected to equipment and personal safety, and having close relationship with energy-conservation and environmental change, timely monitoring and the verification of safety valve set pressure are quite important.
Safety valve is in normally off under opening and closing element is subject to External Force Acting, when the pressure medium in equipment or pipeline increases to over setting, the Special valve of specified value is exceeded by preventing pressure medium in pipeline or equipment to discharge medium outside system, if potential safety hazard can not will be there is by timely Open valve when pipeline or container internal pressure reach certain value in safety valve, according to national regulation, safety valve must verify with timely by periodic detection set-pressure, prior art adopts and valve is disassembled detection check from container or pipeline, and testing result normally set-pressure is qualified, now just need again he to be installed, cause the loaded down with trivial details of work.
Utility model content
For solving the problem, the utility model proposes a kind of pressure vessel relief valve verifying attachment.
A kind of pressure vessel relief valve verifying attachment, comprise safety valve body, described safety valve body comprises main valve and annular seal space, described safety valve body arranged outside has the first pressure transducer, the second pressure transducer is provided with inside described safety valve body, be provided with in described annular seal space, alarm, control chip, storer, LED display, power supply and display screen button, described power supply is connected with storer with alarm, LED display, control chip respectively, and described first pressure transducer is all connected with control chip with the second pressure transducer.
Further, each first pressure transducer of described storer record and the second pressure transducer all detect the initial pressure value of pressure.
Further, described storer is connected with LED display by control chip with the first pressure transducer.
Further, described display screen button is arranged on the on & off switch as display screen in the loop of LED display and power supply composition.
Further, described first pressure transducer is connected into safety valve body and the connecting line place be connected in annular seal space is provided with O-ring seal, and the connecting line surrounding that described second pressure transducer is connected in annular seal space is also provided with O-ring seal.
Further, described annular seal space upper end is provided with the sealed door hinged with valve body.
The utility model compared with prior art, it has following beneficial effect: a kind of pressure vessel relief valve verifying attachment of the present utility model, when coming into operation, do not need safety valve to dismantle when the accuracy detecting safety valve setting value, only the sealed door on safety valve need be opened, because sealed door is an annular seal space relative to safety valve, both Shi Bu UNICOMs, so the unlatching of sealed door does not affect safety valve, after opening closed chamber, press LED switch key, LED just can show the last second pressure transducer and there is force value or force value when reaching certain numerical value, the force value of the first pressure transducer, operating personnel can judge according to both pressure comparisons, when detecting that setting valve is defective namely when the second pressure transducer detects pressure or pressure to certain value, the value of the first pressure transducer is too high or too low, alarm meeting automatic alarm, there is safe and reliable advantage, LED display can show the first pressure transducer in force value at that time simultaneously, dismounting safety valve is needed to verify accurately it when discovery safety valve setting value is defective, must wait until that the first pressure transducer drops to below a certain security value (s), from LED display, operating personnel can know whether safety valve reaches dismounting requirement, carry out timely and accurately detecting and verifying, reduce the fussy degree detected, increase work efficiency.
Accompanying drawing explanation
