Three, summary of the invention
The object of the present invention is to provide a kind of pressure vessels for the chemical industry safety valve that is applicable to that heavy caliber, dismounting, installation are extremely inconvenient, can online periodic check, the pressure vessels for the chemical industry detector of detection.
The technical solution adopted in the present invention is as follows
A kind of instrument for detecting container, its special character is to include center model 3, be respectively equipped with gas source interface on the center model 3, pressure gauge connection, pressure sensor interface and spare interface, source of the gas 1 is connected by the gas source interface of associated line with center model 3, tensimeter 6 and pressure transducer 5 respectively with the pressure gauge connection of center model 3, pressure sensor interface is connected, be provided with pressure-release valve 2 between source of the gas 1 and the center model 3, be provided with container path stop valve 4 between safety valve 7 and the pressure vessels for the chemical industry interface channel, under the situation that container path stop valve 4 cuts off safety valve 7 and pressure vessels for the chemical industry interface channel, safety valve 7 is separated from the pressure vessels for the chemical industry passage, promote, this moment, center model 3 was positioned over safety valve 7 inlets, the opening of the corresponding safety valve 7 of the upper shed face of center model 3 satisfies safety valve 7 verifications by the power source in the center model 3, detect needed pressure;
Around being, the gas source interface of described center model 3, pressure gauge connection, pressure sensor interface and spare interface evenly distribute, the lower surface sealing of center model 3, and upper surface is the opening sealing surface, the opening of opening shape and safety valve 7 is complementary;
It is described that what adopt by the power sources in the center model 3 is nitrogen or pressurized air.
Principle of work of the present invention: by power source input center model 3 with extraneous source of the gas 1, realize the off-line state of safety valve 7, extraneous power source is by center model 3, inject the inlet valve pocket of safety valve 7, make safety valve 7 reach set-pressure and sealing load, realize verification, detection safety valve 7.
A kind of instrument for detecting container of the present invention, solved the weak point that present prior art exists, remedy the limitation of domestic existing safety valve detector, a kind of be applicable to heavy caliber, dismounting, installation extremely online periodic check, the detection of inconvenient pressure vessels for the chemical industry safety valve are provided, use accurately, efficient, sensitive, reliable, need not power supply, easy to carry, very big dissemination is arranged.
Four, description of drawings:
Fig. 1: a kind of instrument for detecting container structural representation;
Fig. 2: the structure cut-open view of center model 3;
Fig. 3: be the vertical view of Fig. 2 center model 3.
Five, embodiment
Provide a kind of reasonable embodiment of the present invention below in conjunction with accompanying drawing.
With reference to figure 1,2,3, a kind of instrument for detecting container, include center model 3, be respectively equipped with gas source interface on the center model 3, pressure gauge connection, pressure sensor interface and spare interface, source of the gas 1 is connected by the gas source interface of associated line with center model 3, tensimeter 6 and pressure transducer 5 respectively with the pressure gauge connection of center model 3, pressure sensor interface is connected, be provided with pressure-release valve 2 between source of the gas 1 and the center model 3, be provided with container path stop valve 4 between safety valve 7 and the pressure vessels for the chemical industry interface channel, under the situation that container path stop valve 4 cuts off safety valve 7 and pressure vessels for the chemical industry interface channel, safety valve 7 is separated from the pressure vessels for the chemical industry passage, promote, this moment, center model 3 was positioned over safety valve 7 inlets, the opening of the corresponding safety valve 7 of the upper shed face of center model 3 satisfies safety valve 7 verifications by the power source in the center model 3, detect needed pressure; Around being, the gas source interface of center model 3, pressure gauge connection, pressure sensor interface and spare interface evenly distribute, the lower surface sealing of center model 3, and upper surface is the opening sealing surface, the opening of opening shape and safety valve 7 is complementary; The making material of center model 3 is No. 20 steel, and all associated lines all adopt 15MPa metal flexible cord, and the power source in the center model 3 adopts nitrogen or pressurized air.
During use, at first, guarantee safe disconnection, do not have dielectric leakage by the interface channel between pressure vessels for the chemical industry passage stop valve 4 closed safe valves 7 and the pressure vessels for the chemical industry.With lifting instrument (lifting jack etc.) safety valve 7 is separated, promotes from pressure vessels for the chemical industry interface channel valve, hoisting depth should be greater than the thickness of center model 3.The size of safety valve 7 bores that the root a tree name is detected, corresponding center model 3 is placed into accurately the porch of safety valve 7, the sealing surface of safety valve 7 and the sealing surface of center model 3 are matched, unclamp the lifting instrument, by thru-bolt 8 with safety valve 7, center model 3, and the pressure vessels for the chemical industry interface channel on flange, tightening together reaches the regulation requirement.
A kind of instrument for detecting container of present embodiment, solved the weak point that present prior art exists, remedy the limitation of domestic existing safety valve detector, a kind of be applicable to heavy caliber, dismounting, installation extremely online periodic check, the detection of inconvenient pressure vessels for the chemical industry safety valve are provided.Use accurately, efficient, sensitive, reliable, need not power supply, easy to carry, very big dissemination is arranged.
