Move freely in housing vertically；The thermal expansion of this heat exchanger shell and tube bank is freely, and completely eliminating the temperature difference should
Power, tube bank can be extracted out, it is simple to cleans.Floating head heat exchanger floating head end structure includes: floating head end housing, sets in floating head end housing
Be equipped with shell flange, floating tubesheet be provided with heat exchanger tube, floating tubesheet can together with heat exchanger tube in housing axially from
By moving.After floating tubesheet has welded with heat exchanger tube, generally housing is carried out the water pressure test, test heat exchanger tube and floating
Whether the weld seam between tube sheet has seepage, current test device to be to utilize O RunddichtringO to be positioned over side flange and floating tubesheet
Between seal and carry out the water pressure test, and if hydraulic test pressure excessive may cause sealing ring from floating tubesheet with
Overflow between side flange and cause test failure, more seriously say and be likely to result in security incident.Also the hydraulic pressure frock of a kind of test is
Binocular structure, outer cylinder body is sleeved on outside inner barrel, and outer cylinder body inwall is provided with baffle ring, and baffle ring is placed with packing, packing
Utilizing inner barrel one end to suppress, inner barrel is attached by flange and bolt with outer cylinder body, and this device can also be carried out
The water pressure test under a certain pressure, but its structure is complicated, and packing hardness is relatively big, during the compacting of inner barrel one end, deflection is relatively
Little, some position is unable to reach and fully seals.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, this utility model provides a kind of simple in construction, is prone to behaviour
Make, security performance is more excellent and the floating head heat exchanger tube head water pressure test frock that can recycle.
This utility model is achieved through the following technical solutions: a kind of floating head heat exchanger tube head water pressure test frock,
Including floating tubesheet, shell flange and frock flange, shell flange is provided with connection seam, described frock flange be provided with
Connect the draw-in groove of seam coupling, be provided with sealing gasket between shell flange and frock flange, the endoporus of frock flange is provided with
Closure gasket groove, described floating tubesheet is arranged in the endoporus of frock flange, and the cylindrical of floating tubesheet is adaptive with closure gasket groove, seals
Being provided with O RunddichtringO and packing in annular groove, the end face of closure gasket groove is provided with the pressure ring being pressed in annular groove, frock flange
Being provided with stud on outer face, pressure ring is fixed on frock flange by nut and stud.
In such scheme, described packing uses oil immersion asbestos packing.
In such scheme, described packing is set to one or more layers in closure gasket groove.
This utility model floating head heat exchanger tube head water pressure test by frock compared with prior art, has following useful effect
Really:
This hydraulic pressure test fixture simple in construction, easy to operate, sealing and safety are higher, it is possible to recycle, it is possible to
Smoothly complete the floating head heat exchanger tube head water pressure test, it is ensured that the quality of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model floating head heat exchanger tube head water pressure test frock；
Fig. 2 is the zoomed-in view in Fig. 1 at A.
In figure: 1. shell flange, 2. sealing gasket, 3. draw-in groove, 4. connect seam, 5. frock flange, 6. bolt, 7. nut,
8.O RunddichtringO, 9. packing, 10. pressure ring, 11. fixed bolts, 12. nuts, 13. floating tubesheets, 14. heat exchanger tubes.
Detailed description of the invention
With specific embodiment this utility model floating head heat exchanger tube head water pressure test recruitment pretended below in conjunction with the accompanying drawings into
The description of one step:
Fig. 1 is the structural representation of this utility model floating head heat exchanger tube head water pressure test frock, and Fig. 2 is in Fig. 1 at A
Zoomed-in view.In figure, this floating head heat exchanger tube head water pressure test frock, including floating tubesheet 13, shell flange 1 and work
Dress flange 5, shell flange 1 is provided with connection seam 4, and described frock flange 5 is provided with and the draw-in groove 3 being connected seam 4 coupling,
It is provided with sealing gasket 2 between shell flange 1 and frock flange 5, plays end face seal effect, between shell flange 1 and frock flange 5
Being fixed by bolt 6 and nut 7, the endoporus of frock flange 5 is provided with closure gasket groove, floating tubesheet 13 is arranged on frock flange
In the endoporus of 5, the cylindrical of floating tubesheet 13 is adaptive with closure gasket groove, is provided with O RunddichtringO 8 and packing 9, O in closure gasket groove
RunddichtringO 8 is arranged on the bottom of closure gasket groove, and the end face of closure gasket groove is provided with the pressure ring 10 being pressed in annular groove, frock method
Being provided with stud 11 on the outer face of blue 5, pressure ring 10 is fixed on frock flange 5 by nut 12 and stud 11.
During the water pressure test, only frock flange 5 need to be fixed on shell flange 1, due to housing by bolt 6 and nut 7
Sealing gasket 2 is set between flange 1 and frock flange 5, so tights a bolt 6 and nut 7, between shell flange 1 and frock flange 5
Just can seal fixing；Arranging O RunddichtringO 8 and packing 9 between frock flange 5 and floating tubesheet 13 circumference, packing 9 can be 1 layer
It is alternatively multilamellar, tightens stud 11 and nut 12 makes pressure ring 10 compress packing 9 and O RunddichtringO 8, such O RunddichtringO 8 and dish
Root 9 deforms under the compacting of pressure ring 10, seals up the space of frock flange 5 and floating tubesheet 13.O type in this utility model
Sealing ring 8 uses rubber to make and is easily deformed, and packing 9 uses oil immersion asbestos packing.Whole floating head can be changed with that
The housing of hot device carries out the water pressure test, the tube head of detection heat exchanger tube 14 whether seepage.After inspection, first pull down pressure ring 10, then
Unclamp the bolt 6 between frock flange 5 and shell flange 1 and nut 7, thus structure for pressure test can be removed, this floating head
Heat exchanger tube head water pressure test frock can continue to reuse.Whole pressure testing process need not welding, and operation is convenient, sealing
And safety is higher, so substantially increases work efficiency and pressure testing safe coefficient, and be prevented effectively from drawing crack floating tubesheet 13
And the weld seam between heat exchanger tube 14, is greatly improved the quality of product.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, although this utility model is disclosed above with preferred embodiment, but is not limited to this utility model, any ripe
Know professional and technical personnel, in the range of without departing from technical solutions of the utility model, when available the disclosure above method and
Technology contents makes a little Equivalent embodiments changing or being modified to equivalent variations, as long as being without departing from this utility model technology
The content of scheme, any simple modification above example made according to technical spirit of the present utility model, equivalent variations with
Modify, still fall within the range of technical solutions of the utility model.
