Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As depicted in figs. 1 and 2, tubular heat exchanger quick leak-checking device of the present utility model comprises operation valve 13, is connected with hollow adjusting packoff at the endpiece 14 of operation valve 13, and hollow adjusting packoff and heat exchanger tube inner chamber are suitable.
During inspection, an above-mentioned tubular heat exchanger quick leak-checking device respectively is installed at the two ends of same heat exchanger tube, the tubular heat exchanger quick leak-checking device of one end is used for sealing and fast pressure relief, the tubular heat exchanger quick leak-checking device of the other end and pressure-source communication are used for sealing and pressurising fast, use operation valve control pressurising and stress-relief process, hollow adjusting packoff and heat exchanger tube inner chamber are suitable, use hollow adjusting packoff to make the heat exchanger tube closed at both ends, within a certain period of time whether the heat exchanger tube after working pressure table 5 is observed closed at both ends in the pressure medium stream pressurize, pressurize can not be judged to be and damage, not pressurize can be judged to be leakage, need to change, thereby can exchange heat pipe fast and pursue root leak detection investigation, checked operation is fast convenient, check result accurately and reliably, thereby effectively shortened the supervision time, improved checking efficiency.
Described hollow adjusting packoff is connected to the endpiece 14 of operation valve 13 by connecting pipe 16, when the heat exchanger tube that is used for different tube diameters is checked, only needs to change hollow adjusting packoff, and is convenient.
Described hollow adjusting packoff can adopt following structure: expansion-head 10 1 ends of tubulose are connected with connecting pipe 16, the other end of expansion-head 10 is provided with seam 15, is disposed with rubber ring 8, movable sleeve 11 and movable sleeve holding device by seam 15 on the expansion-head 10 of connecting pipe 16.When the movable sleeve holding device held out against, rubber ring 8 was radially expanded by seam 15 and movable sleeve 11 extruding, closely contacts with the heat exchanger tube inwall, thereby makes the heat exchanger tube termination sealed.
Regulate for ease of sealing, described movable sleeve holding device is to be arranged on spring 6 between movable sleeve 11 and the connecting pipe 16, to be installed in the compression handles 7 on movable sleeve 11 and the connecting pipe 16 and to be arranged on handle 12 on the connecting pipe 16, in the time of need holding out against movable sleeve 11, need be fulcrum only with handle 12, unclamp compression handles 7, under the effect of spring 6, can make movable sleeve 11 extruding rubber rings 8, reach sealing effectiveness.Certainly, this structure is changed slightly, make compression handles 7 change application of force direction, rubber ring 8 is squeezed, but also want the charged pressure medium after considering sealing, such change will increase the labour intensity of operation, be good with last scheme still.
For guaranteeing the sealing effectiveness of heat exchanger tube end, can at least two rubber rings 8 be set between seam 15 and movable sleeve 11, be provided with expansion sleeve 9 between two adjacent rubber rings 8.
For ease of operation, described operation valve 13 can adopt spray gun 2, and spray gun 2 is connected with pressure source by pipe adapter 1.As shown in Figure 1, needle-valve 3 and needle-valve handle 4 are installed on the spray gun 2, when needing air inlet, depress needle-valve handle 4 and can make tubular heat exchanger quick leak-checking device of the present utility model and pressure-source communication.Described pressure source can be pressure gas source or pressure liquid source.
For ease of observing, can the tensimeter 5 that be communicated with the inner chamber of hollow adjusting packoff be set in endpiece 14 backs of operation valve 13, tensimeter 5 can an installation leakage detection apparatus at one end on, and the equal setting pressure of leakage detection apparatus table 5 that needn't two ends.
Embodiment:
This tubular heat exchanger quick leak-checking device can be converted by spray gun 2, mainly is made up of pipe adapter 1, spray gun 2, needle-valve 3, needle-valve handle 4, tensimeter 5, spring 6, rubber ring 8, compression handles 7, expansion sleeve 9, movable sleeve 11 and expansion-head 10.
This device must use in pairs, and its structure is identical, but uses different.One is used for quick pressurising, must be connected with pressure source, and one is used for fast pressure relief.Stream oriented device is aimed at two terminations of same heat exchanger tube simultaneously during use, with handle 12 is fulcrum, the compression handles 7 of holding with a firm grip is inserted heat exchanger tube fully with expansion-head 10 to movable sleeve 11, unclamps compression handles 7 then, under the effect of spring 6, expansion-head 10 produces action to axial with movable sleeve 11, makes rubber ring 8 produce elastic deformation, radially expands, make it closely to contact, reach sealing and fixation with the inwall of heat exchanger tube.At this moment depress the needle-valve handle 4 of pressurising end, carry out quick pressurising, and observe tensimeter 5, when reaching inspection pressure, unclamp needle-valve handle 4, the seeking time internal pressure not fall, represent that promptly this heat exchanger tube does not have leakage.Depress the needle-valve handle 4 that unloads pressure side again and carry out fast pressure relief, depress the compression handles 7 at two ends then, compression spring 6, rubber ring 8 is done the time spent in no external force, be radially expanded disappearance, cushion rubber returns to the state before the elastic deformation, no longer closely contacts with the inwall of heat exchanger tube, expansion-head 10 can be extracted from heat exchanger tube, and the leak detection of a heat exchanger tube finishes.By that analogy, can hunt leak by root.
Need to prove: should do air-tight test or hydrostatic test under the corresponding test pressure before this device uses, guarantee that this device sealing meets tightness test or hydrostatic test requirement; Press the difference of heat exchange tube diameter, dispose different expansion-head 10, expansion sleeve 9, movable sleeve 11 and rubber ring 8, only need to change this cover combination, just can carry out quick leak-checking the heat interchanger of different tube diameters; The pressure medium that leak detection is used can working pressure gas, also can working pressure liquid, according to field condition, can grasp flexibly.
