The utility model discloses a high pressure angle valve quality detection device is with solving repairing quality was examined to high -pressure angle valve after the maintenance a device, it overhauls and to leak or outer problem of leaking in appearing when moving after unqualified successfully to have stopped high -pressure angle valve, the passive situation that high -pressure angle valve repairing quality can only come into operation and inspect afterwards through the device has been changed in the past, through detect the repairing quality who has ensured high -pressure angle valve to high -pressure angle valve, thereby the emergence of leakage accident has been avoided, thereby the grinding quality and equipment quality of high -pressure angle valve have been inspectd, the finish integrity of put into service's angle valve of each maintenance has been ensured, security and reliability.
Description
Technical field
The utility model belongs to pick-up unit technical field, is specifically related to a kind of high-pressure angle valve quality detection device.
Background technology
At present, the TECACES technique that urea production adopts, high-pressure angle valve is the critical equipment in this process unit, its effect is effective critical control point of process for producing urea, high-pressure angle valve is mainly used in urea high-tension ring, and the pressure born during operation is high, and temperature is high, the processing medium very strong with corrosivity contacts, the how easy generation corrosion leakage of seal point.If leak, very large impact is caused on normal production, the medium leaked not only causes environmental pollution, and corrosive medium causes carbon steel securing member and has corrosion, very large hidden danger is caused to safety in production, thus whether high-pressure angle valve normally runs and play very important effect in the daily production of urea plant, not only needs the workmanship that valve will have, and also needs the proper operation of maintainer simultaneously and meticulously safeguards.
The structure of high-pressure angle valve by handwheel, topworks, supporting studs, circumferential limited block, connect the parts such as double ring set and axle jump ring, valve rod, gland and gland, filler, valve body, valve rod and valve head (being wholely set), valve seat and valve body inlet pipe nipple and form; The static and dynamic sealing point of high-pressure angle valve is more, as between valve rod and filler, valve body and valve base chamber, valve head and valve base chamber, between valve seat and valve body inlet pipe nipple etc.If there are seal point existing problems in maintenance process, high-pressure angle valve runs under High Temperature High Pressure, strong corrosive medium occasion, is easy to cause leakage.The lighter can cause the pressure sealing operation of leak source, and safeguard causing very large cost burden to device, bring very large potential safety hazard to device production run, severe one causes whole urea plant to stop, and causes huge economic loss to company.But cannot checking repair quality after existing high-pressure angle valve maintenance, can only carry out passive inspection afterwards by coming into operation, the high-pressure angle valve after this just gives maintenance normally uses and brings great potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of high-pressure angle valve quality detection device, cannot detect the problem of its quality after solving the maintenance of existing high-pressure angle valve.
The technical scheme that the utility model adopts is: a kind of high-pressure angle valve quality detection device, comprise the connector be connected with the import and export flange of high-pressure angle valve, connector is provided with joint, connector is also connected with high-pressure hose by joint, the other end of high-pressure hose is connected with pressuring pump, and pressuring pump is provided with piezometer.
Feature of the present utility model is also,
High-pressure hose is the connecting pipe of high pressure resistant band metal inner lining.
Pressuring pump is manual pressuring pump.
The model of manual pressuring pump is SYL-7.6/25.
The beneficial effects of the utility model are: a kind of high-pressure angle valve quality detection device of the present utility model cannot check the problem of its quality after solving the maintenance of existing high-pressure angle valve.The passive situation that after a kind of high-pressure angle valve quality detection device of the present utility model high-pressure angle valve maintenance in the past, quality can only be checked afterwards by coming into operation, ensure that integrity, the safety and reliability of the complete angle valve be delivered for use of each maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-pressure angle valve quality detection device of the present utility model;
Fig. 2 is the structural representation of connector in Fig. 1.
In figure, 1. high-pressure angle valve, 2. connector, 3. high-pressure hose, 4. piezometer, 5. pressuring pump.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of high-pressure angle valve quality detection device that the utility model provides as depicted in figs. 1 and 2, comprise the connector 2 be connected with the import and export flange of high-pressure angle valve 1, connector 2 is provided with joint, connector 2 is also connected with high-pressure hose 3 by joint, the other end of high-pressure hose 3 is connected with pressuring pump 5, pressuring pump 5 is provided with piezometer 4.
High-pressure hose 3 is the connecting pipe of high pressure resistant band metal inner lining.
Pressuring pump 5 is manual pressuring pump, and its model is SYL-7.6/25.
Example, connector 2 can oneself be processed, and it selects 20 of modifier treatment
#the operations such as steel is rough turn through Linear cut blanking, lathe, finish turning, boring, mantle fiber are processed into a series of coupling assembling meeting various high-pressure angle valve size, connector 2 are provided with for matching the joint be connected with high-pressure hose 3; High-pressure hose 2 selects the high pressure hose connector of the high pressure resistant band metal inner lining of 450MPa level; Manual pressuring pump selection rated pressure is 25MPa, model is the high-pressure pump of SYL-7.6/25; Measurement range selection 0 ~ the 30MPa of piezometer 4.
During use, first connector 2 is first connected with the suction flange of high-pressure angle valve 1, be connected with high-pressure hose 2 by joint again, the other end of high-pressure hose 2 is connected to manual pressuring pump, then utilizes water tank to intake in manual pressuring pump and suppresses, drain the air in high-pressure angle valve 1 cavity, pressure is elevated to gradually 1.1 times of high-pressure angle valve 1 operate pressure, pressurize 30min, checks each seal point, and high-pressure angle valve 1 is then qualified without invariant position pressure shown in outer leak source, non-internal leakage, piezometer 4 pointer; After connector 2 and the discharge flange of high-pressure angle valve 1 being connected after removing connector 2, being detected by same detection mode of suppressing, if high-pressure angle valve 1 is still without invariant position pressure shown in outer leak source, non-internal leakage, piezometer 4 pointer, is qualified again.
A kind of high-pressure angle valve quality detection device of the present utility model is used to solve a kind of device of high-pressure angle valve at inspection survey of repairs repair quality, successfully stop the problem occurring interior leakage or leak outside when high-pressure angle valve overhauls defective rear operation, change high-pressure angle valve repair quality in the past to be come into operation the passive situation checked afterwards by device, by detecting the repair quality that ensure that high-pressure angle valve to high-pressure angle valve, thus avoid the generation of leakage accident, thus examine Grinding Quality and the assembling quality of high-pressure angle valve, guarantee the reliability of overhauling rear use.
