Description
Technical field
This utility model belongs to compensation of pipeline field, and institute's utility model is a kind of bend pipe based on corrugated tube and sleeve design
The advantage of corrugated tube and sleeve is dexterously combined by pressure-balancing type compensator, has the characteristics that low cost.
Background technology
Corrugated tube is a kind of flexible compensation element, axial, the horizontal and angular displacement in being compensated with suction line, extensively
Apply compensation of pipeline design in.Corrugated tube in normal operation, will bear pipeline pressure load and bear position again
Transfer lotus, stress state is complicated, simultaneously takes account of etching problem, the selection of therefore generally corrugated tube is higher than pipe material rank,
For example, generally in hot water and vapour system pipeline, corrugated tube generally adopts austenitic stainless steel, such as 316L, therefore cost relatively
High.
Sleeve expansion joint also can be compensated to the displacement in pipeline using gland sealed form, is typically limited to axial direction
The compensation of displacement, compared with bellow-type expansion application, its cost is relatively low to be a big advantage.
The utility model proposes a kind of bend pipe pressure balance type compensator based on corrugated tube and sleeve design, for being situated between
Mass flow to change at, working end arranges corrugated tube, and balance end arranges sleeve, and corrugated tube and sleeve design realize displacement jointly
Compensate, and introduce sleeve and compare the manufacturing cost that all can reduce compensator using corrugated tube design.
Utility model content
The advantage of comprehensive bellow-type expansion and compensating sleeve is it is proposed that a kind of bend pipe pressure based on corrugated tube and sleeve design
Dynamic balance type compensator, is applied to expand the new approaches of compensation of pipeline design at the change of medium flow direction, adopts simultaneously and all
Reduce cost with corrugated tube design.
For realizing above-mentioned technical purpose, be employed technical scheme comprise that：A kind of bend pipe based on corrugated tube and sleeve design
Pressure-balancing type compensator, including end pipe, corrugated tube, elbow assembly, adapter and end socket, one end of corrugated tube is connected with end pipe,
Its other end is connected with elbow assembly, and the elbow wall of elbow assembly is connected with one end of adapter, the other end of adapter and end socket
Connect, described end socket is sleeve end socket, the outer wall of end socket is connected with the outer wall of end pipe by pull bar, and end socket one end seals, separately
One end open is simultaneously set in outside adapter, is provided with black box between the opening and the outer wall of adapter of end socket, the opening of end socket
Mouth end and adapter relative movement are arranged.
Black box described in the utility model is packing seal assembly.
Packing seal assembly described in the utility model includes gland and airtight and watertight padding, and gland is arranged on the opening of end socket
End, is provided with seal ring, gland, the outer wall of end socket inwall, seal ring and adapter surround for placing on the opening inwall of end socket
The packing cavity of airtight and watertight padding, gland is connected with the opening of end socket by bolt, and airtight and watertight padding is compressed.
Airtight and watertight padding described in the utility model is politef packing.
The opening of end socket described in the utility model is provided with the lute pipe nozzle connecting with packing cavity.
This utility model beneficial effect is：This compensator can apply at the change of medium flow direction, realizes pipeline axially
Displacement and the compensation of lateral displacement, working end arranges corrugated tube, and balance end arranges sleeve, reduces the application cost of compensator,
The new approaches of compensation of pipeline design are expanded.

Specific embodiment
The working end setting corrugated tube of compensator, the compensation of achievable axial displacement and lateral displacement；The balance of compensator
End setting sleeve, realizes axial displacement and compensates, and corrugated tube one end and sleeve one end adopt end plate to constrain blind flange force with Tiebar structure,
Realize the balance of pressure, compensator does not externally export blind flange force.The compensator of this kind of form due to being provided with ball, taper faced washer,
Frictional force between ball, taper faced washer can be balanced each other with the cross force of working end, and therefore balance end only has the compensation of axial displacement,
Therefore cleverly introduce sleeve expansion joint design in balance end, elbow has pressure port, realize working end and balance end pressure
UNICOM, sleeve expansion joint taken over by setting（Gasket ring）Realize the effective area of corrugated tube and the effective area phase of tube-in-tube structure
With.When compensator bears compression displacement, that is, during the compression of working end, sleeve balance end stretches；When compensator bears stretching displacement
When, sleeve balance end is compressed.Corrugated tube and sleeve are compensation original paper, due to introducing compensating sleeve design, with whole setting ripples
Stricture of vagina pipe compensates and compares, and cost reduces, and on the other hand, if provided as corrugated tube, it is not under occurring post instability condition for balance end
Maximum wave number be working end corrugated tube quantity half, therefore to have an institute limited for compensation dosage, and balance end is set to sleeve, then
There is not post unstability.
Sealing between sleeve balance end and adapter does not affect the sealing group of compensating sleeve movement using achievable sealing again
Part, black box can adopt mechanism seals, packing seal.Black box is being flowed perpendicular to the end face of rotation axiss by least one pair of
Body pressure and compensation mechanism elastic force（Or magnetic force）Effect and auxiliary seal cooperation under keep laminating and with respect to slip structure
The device preventing fluid leakage becoming.
As shown in Figure 1, 2, a kind of bend pipe pressure balance type compensator based on corrugated tube and sleeve design is by end pipe 1, end
Board component 2, shipment bar 3, corrugated tube 4, intervalve 5, guide shell 6, elbow assembly 7, pull bar 8, adapter 9, bolt 10, gland 11,
Nut 12, airtight and watertight padding 13, overcoat cartridge module 14, ball, taper faced washer 15, pull-rod nut 16, end socket 17 form, overall from structure
Composition from the point of view of, one end of elbow is bellows structure, and opposite side is tube-in-tube structure, and bellows structure can compensate stretching, press
Contracting and lateral displacement, tube-in-tube structure is passed through gland 11, politef packing and overcoat cartridge module 14 and is realized sealing, can compensate
Stretching and compression displacement, so entire compensation device structure can flow to axial direction and the lateral displacement at change with compensation medium.Elbow
On have pressure port, working end and balance end are realized by end board assembly 2, pull bar 8, ball, taper faced washer 15 and pull-rod nut 16
Connection, the effective area of corrugated tube is identical with the effective area of tube-in-tube structure, thus realizing the constraint of blind flange force, compensator is whole
Body does not externally export blind flange force.
As shown in Figure 3,4, compensator setting lute pipe nozzle 18, can be to the airtight and watertight padding politef packing of sleeve at
Add lute, the addition of lute can make the sealing effectiveness of sleeve more preferable, bear bigger pressure rating, can with pressure relatively
Use under high operating mode, in addition in engineering actual moving process, within certain time between overhauls(TBO), lute pipe can be passed through to sleeve
Nozzle adds lute, improves sealing effectiveness in running for the sleeve and service life.
