Abstract
The utility model discloses a pressure test device for floating-head type heat exchangers, which is formed by a connecting flange, a short connection pipe, a sealing ring cover and a press cap at the floating-head end of the heat exchanger. The connecting flange of the floating head is fixedly connected with the short connection pipe, the outer end of the short connection pipe is fixedly connected with the sealing ring cover, a floating pipe plate is embedded into the sealing ring cover and is circumferentially seated into a sealing ring, a press cover is inserted into the sealing ring cover and is tightly pressed against the sealing ring, a pipe end of the inner port of the press cover pressing on the sealing ring is cuniform. The short connection pipe is provided with a connecting pipe connector, and the connecting pipe connector is provided with a screwed plug. The utility model has the advantages of saving raw materials, low cost, shortening production cycle, reducing pressure test time, improving overhaul efficiency of the heat exchanger, and is a pressure test device for floating-head type heat exchangers with simple and convenient operation, safety, reliability and accurate leaking pipe bundle judgment.
Description
Technical field
The utility model belongs to pressure testing device, particularly relates to a kind of movable tube sheets heat exchanger pressure testing device.
Background technology
A large amount of movable tube sheets heat exchangers are arranged in the oil-refining chemical process units, when movable tube sheets heat exchanger manufacturing, maintenance, the leak detection program that heat exchanger tube is connected with floating tubesheet is the tube head pressure testing, must adopt special-purpose structure for pressure test that open housing and heat exchanger fuse are closed, form enclosed cavity, could guarantee that pressure testing is satisfactory for result.Present domestic movable tube sheets heat exchanger pressure testing device generally adopts TEMA standard " leak detection of E-4.13 pipe " method to carry out, and this method is shell-and-tube heat exchanger manufacturing firm employing both at home and abroad widely.Carrying out floating tubesheet tube head pressure test leak-detecting with the TEMA standard method needs the special pressure testing mold of a cover, comprises structure for pressure test, filler, gland, pad and some studs, nut etc.Though this floating tubesheet tube head pressure testing mold is simple in structure, easy installation and removal and safe and reliable need be with the heavy in section forging system of sending a car, and one-time investment is big, and interchangeability is poor, and a cover mold is only applicable to the heat exchanger of a kind of nominal diameter and pressure rating.And after tube bank and housing assembling, when the relative distance of floating tubesheet and outer skull side flange sealing surface surpassed certain limit, filler just can not be fitted on the floating tubesheet excircle well, does not also guarantee excellent sealing.Domestic other improvement type also is to encrypt the packing material on the floating tubesheet cylindrical, compresses the method for airtight and watertight padding with gland, and this device exists also that weight is big, poor, the nonadjustable shortcoming of sealing station of versatility.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, provides a kind of pressure testing effective, lightweight movable tube sheets heat exchanger pressure testing device.
Movable tube sheets heat exchanger pressure testing device of the present utility model is that the floating head end at heat exchanger is made of adpting flange, nipple, seal ring set and pressure cap.Raising the nose above water to breathe adpting flange fixedlys connected with nipple, the nipple outer end is fixedly connected seal ring set, floating tubesheet is embedded in the seal ring set, floating tubesheet ring week seat go into sealing ring, it is interior and compress sealing ring that gland inserts seal ring set.
As further improvement of the utility model, on nipple, be provided with the tube connector joint, on the tube connector joint, plug is arranged.
As further improvement of the utility model, the pipe end that is pressed on the sealing ring of gland inner port is a wedge shape.
As further improvement of the utility model, adpting flange is that bolt is connected with the heat exchanger flange, and gland is connected with the studding bolt with seal ring set.
Movable tube sheets heat exchanger pressure testing device of the present utility model is the weight that alleviates structure for pressure test, and the bolt hole of adpting flange is replaced, has seal groove with connecting journal stirrup on adpting flange; In order to reach the effect used one to adapt to the variation of shell flange bolt hole center distance more, the connecting hole of journal stirrup is designed to the radially slotted hole of different-diameter, and the quantity of journal stirrup is the least common multiple of several (1.0MPa, 1.6MPa, 2.5MPa, 4.0MPa) shell flange; In order to adapt to the variation of the movable tube sheets heat exchanger flange and the various degree of depth of tube sheet, adopt the seal ring set structure of lengthening, and adopt the stud of adjustable axial distance to connect gland and seal ring set, but make the distance free adjustment between shell flange and the floating tubesheet; For the enhanced leaktightness effect, adopt the O-ring seal design that strengthens, to realize the contact force automatic compensation type sealing of structure for pressure test and heat exchanger.Adopt above-mentioned method for designing to make structure for pressure test have good versatility, make the weight of structure for pressure test reduce to about 50% of original structure simultaneously.So both having saved material, and reduced the frock expense, and can shorten fabrication cycle again, and reduced the pressure testing time, and improved the heat exchanger overhaul efficiency, is a kind of easy and simple to handle, safe and reliable and can accurately judge the movable tube sheets heat exchanger pressure testing device that leaks tube bank.
Description of drawings
Figure of description is the structural representation of the utility model movable tube sheets heat exchanger pressure testing device.
The specific embodiment
Movable tube sheets heat exchanger pressure testing device of the present utility model is at the floating head end of heat exchanger adpting flange, nipple, seal ring set and pressure cap to be installed to constitute, adpting flange 1 welds mutually with nipple 2, weld mutually with seal ring set 3 outer end of nipple 2, floating tubesheet 4 is embedded in the seal ring set 3, the ring week seat of floating tubesheet 4 is gone into sealing ring 5, gland 6 inserts in the seal ring set 3 and compresses sealing ring 5, the pipe end that is pressed on the sealing ring 5 of gland 6 inner port 9 is a wedge shape, and gland 6 is connected with seal ring set 3 usefulness studding bolts 11.Adpting flange 1 and heat exchanger flange 10 have annular seal groove for bolt is connected on adpting flange 1, add sealing ring in the groove with the space of airtight heat exchanger flange 10 with adpting flange 1.
During use, at first adpting flange 1 is connected with heat exchanger flange 10, the bolt hole of adpting flange 1 is a slotted hole, can be connected with the shell flange of different nominal pressures, same nominal diameter.Then sealing ring 5 tightly is attached on the floating tubesheet 4, compresses, at last gland 6 is connected with seal ring set 3 usefulness studding bolts 11, suppress from the inlet opening water inlet with gland 6.On nipple 2, be provided with tube connector joint 7, plug 8 is arranged on tube connector joint 7, when single heat exchanger is carried out pressure testing, union nipple 7 is closed with plug 8; When two heat exchanger series connection, can open pipe cap 8 and intake or discharge water by union nipple 7.
