Abstract
The utility model discloses the quick pressure test frock of a kind of heat exchanger tube not damaged, belong to the tooling device of machinery industry.The quick pressure test frock of heat exchanger tube not damaged, comprises the packoff at heat exchanger tube two ends.One end of heat exchanger tube is closed by independently A packoff, and the B packoff that the other end of heat exchanger tube is equipped by joint test is closed, and operating personnel only need the set nut of the packoff tightening heat exchanger tube two ends, can complete the preliminary work of withstand voltage test.Handling fast, very convenient, and for heat exchanger tube not damaged.Employing different from the past welding closure plate, time-consumingly takes material.Simultaneously to take production site little for this frock, and bend pipe, endless tube are applicable equally.
Description
Technical field: the utility model belongs to the tooling device of machinery industry, especially a kind of pressure test frock.
Background technology: heat exchanger tube is explicitly provided main pressurized element in TSG R0004-2009 " fixed safe technology of pressure vessel Supervision Code ", always run into welding in the fabrication process, the manufacturing process such as bending, inevitably will exchange heat pipe and again do withstand voltage test after the above-mentioned situation of generation.Did withstand voltage test is all weld with closure plate the effect that heat exchanger tube two ends reach airtight in the past, and the whole withstand voltage test of every root heat exchanger tube completes and probably needs 2-3 people.30 minutes, the expense that wastes time and energy is expected.
Summary of the invention: technical problem to be solved in the utility model is to provide the quick pressure test frock of a kind of heat exchanger tube not damaged, technique is simple in test, operation easier is little for it, assembling is quick, labour intensity is low, the purpose of this utility model is achieved in that the quick pressure test frock of heat exchanger tube not damaged, comprises the packoff at heat exchanger tube two ends.One end of heat exchanger tube is closed by independently A packoff, and the B packoff that the other end of heat exchanger tube is equipped by joint test is closed, and the connecting line of B packoff and rig for testing is equipped with tensimeter (8) and stop valve (9).Independently A packoff has a sealing block and a set nut.Sealing block has the threaded circular hole that larger than heat exchanger tube bore, and a darker annular groove identical with bore inside and outside heat exchanger tube is arranged at the bottom of circular hole, is seal boss, bottom the circular hole outside annular groove, O-ring seal is housed in the middle of annular groove.B sealing block and the A sealing block of the B packoff of joint test equipment have approximate structure, and the seal boss only in its annular groove has duct to communicate with the connecting line of rig for testing.
The quick pressure test frock of heat exchanger tube not damaged, operating personnel only need the set nut tightening heat exchanger tube two ends can complete the preliminary work of withstand voltage test, singlely just can complete.Handling fast, very convenient, and for heat exchanger tube not damaged.Employing different from the past welding closure plate, time-consumingly takes material.Simultaneously to take production site little for this frock, and bend pipe, endless tube are applicable equally.
Accompanying drawing illustrates: Fig. 1 is the structural representation of the quick pressure test frock of heat exchanger tube not damaged.
Embodiment: be further described below in conjunction with width figure.
As shown in drawings, the quick pressure test frock of heat exchanger tube not damaged, is made up of the packoff at heat exchanger tube two ends.One end of heat exchanger tube is closed by independently A packoff, and the B packoff that the other end of heat exchanger tube is equipped by joint test is closed, and the connecting line of B packoff and rig for testing is equipped with the tensimeter 8 of detection experiment pressure and the stop valve 9 of closed heat exchanger tube.
Independently A packoff has an A sealing block 1 and a set nut 5; A sealing block 1 has the threaded hole that larger than heat exchanger tube 6 bore, a darker annular groove 2 identical with bore inside and outside heat exchanger tube is arranged at the bottom of circular hole, seal boss 4 in the middle of annular groove, O-ring seal 3 is housed bottom the threaded hole outside annular groove, and the set nut 5 of heat exchanger tube coordinates with threaded hole.Set nut tightens the effect that rear seal boss and O-ring seal reach interior external seal, there will not be the situation of leakage in withstand voltage test process.
The B sealing block 7 of the B packoff of joint test equipment has approximate structure with A sealing block 1, and the seal boss only in its annular groove has duct to communicate with the connecting line of rig for testing.Heat exchanger tube one end is inserted the annular groove of A sealing block, tighten set nut.The test end of heat exchanger tube is inserted B packoff, the set nut of tightening test end.Open stop valve, test(ing) medium enters heat exchanger tube, can start withstand voltage test.
