Description

A kind of external pressure of heat exchange tube pick-up unit
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of external pressure of heat exchange tube pick-up unit.
Background technology
Heat interchanger is widely used in all trades and professions at present, often owing to the former thereby unstability of pipe fitting self or design, brings a lot of unnecessary loss for manufacturing and designing of heat interchanger in the hydraulic testing of the heat exchanger tube in the heat interchanger after manufacturing is finished.Analyze reason and mainly be in most of heat interchanger and to bear the limited in one's ability of external pressure when heat exchanger tube is operated in outer pressure condition, usually because external pressure effect meeting causes the unexpected external pressure unstability of heat exchanger tube, has Unpredictability, not only engineering is caused damage, also become simultaneously a kind of potential safety hazard, design formula is an experimental formula also often, can not be found the solution accurately, brings a lot of inconvenience for the application of engineering.And also lack it in the prior art and bear external pressure mechanics performance detection device.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of external pressure of heat exchange tube pick-up unit, can solve the external pressure destabilization problems that heat exchanger tube exists, and has improved the reliability of design, stop potential safety hazard, thereby can avoid unnecessary economic loss.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of external pressure of heat exchange tube pick-up unit, comprise pressure testing container 1, be separately installed with valve 2, exhaust-valve 3, pressurizing valve 12, blowdown valve 13, tensimeter 4, safety valve 5 and viewport 11 on the pressure testing container 1, slideway 9 is installed in the pressure testing container 1, be equipped with the one group of V-type frame 8 that can place pressure testing heat exchanger tube 10 on the slideway 9, pressure testing heat exchanger tube 10 1 ends dispose pressure testing tire 7 and by 6 sealings of cecum plug, and the pressure testing tire 14 of the other end is connected with valve 2 on the pressure testing container 1.
Described pressure testing container 1 can bear the interior pressure higher than pressure testing heat exchanger tube 10 external pressures.
The adjustable height of described V-type frame 8, centre-height and position, the left and right sides should guarantee that pressure testing heat exchanger tube 10 is in the center of pressure testing container 1.
Described viewport 11, V-type frame 8, slideway 9 are distinguished at least one.
Described pressure testing heat exchanger tube 10 can be prefabricated into required shape.
Described pressure testing tire 7,14 can be installed according to the prefabricated shape of pressure testing heat exchanger tube 10.
The utility model can charge into pressure testing working medium separately in pressure testing container 1 when detecting, pressure testing heat exchanger tube 10 is under the external pressure effect; Also can in pressure testing heat exchanger tube 10 inside and pressure testing container 1, charge into pressure testing working medium respectively simultaneously, pressure testing heat exchanger tube 10 is under the symphyogenetic condition of inside and outside pressure, detect the performance that pressure testing heat exchanger tube 10 bears external pressure.The utility model is simple in structure, just can detect by the ability that test exchange heat pipe bears external pressure when engineering design, has improved the reliability of design greatly, has stopped potential safety hazard.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in detail.
With reference to accompanying drawing, a kind of external pressure of heat exchange tube pick-up unit, comprise pressure testing container 1, be separately installed with valve 2 on the pressure testing container 1, exhaust-valve 3, pressurizing valve 12, blowdown valve 13, tensimeter 4, safety valve 5 and viewport 11, slideway 9 is installed in the pressure testing container 1, be equipped with one group of V-type frame 8 on the slideway 9, can be placed with pressure testing heat exchanger tube 10 on the V-type frame 8, pressure testing heat exchanger tube 10 1 ends dispose pressure testing tire 7 and seal by cecum plug 6, the other end disposes pressure testing tire 14, pressure testing tire 14 by loose joint 15 with take over 16 and communicate, take over 16 and be connected with valve 2 on the pressure testing container 1 again.
Described pressure testing container 1 can bear the interior pressure higher than pressure testing heat exchanger tube 10 external pressures.
