Abstract
The utility model discloses an externally braced high-pressure anti-accumulation pressure balanced universal expansion joint, which comprises a working corrugated pipe assembly (1) mounted on outside of a connecting pipe assembly (4), and a balancing corrugated pipe assembly (2) and a working corrugated pipe assembly (3) which are sequentially connected with the working corrugated pipe assembly (1). A lapping portion of the connecting pipe assembly (4) and the connecting pipe assembly (5) is equipped with a flexible sealing assembly (9), pull rods are further disposed outside the corrugated pipes, and blowing assemblies are mounted at end portions in the medium inlet direction of the working corrugated pipe assembly and the balancing corrugated pipe assembly. Through the procedures, the purpose of completely preventing dust accumulation can be achieved while rigidity of the corrugated pipes can be reduced, and therefore the expansion joint is particularly applicable to small-bore high pressure pipelines with dust particles as media and between two devices in modern petroleum, chemical industrials and the like.
Description
Technical field
The utility model relates to a kind of expansion joint, is applicable to that medium is the small-bore high pressure line of dust granules.
Background technique
For guaranteeing conveying property, medium is that the high pressure line of dust granules mostly is vertical or true dip direction, and its two ends respectively connect two equipment.For the solution problem of expanding with heat and contract with cold need be provided with expansion joint, for reducing thrust to equipment, the pressure balance expansion joints that adopt more, and for pitch pipe, not only there is axial displacement, but also have lateral displacement, need with this understanding to adopt to absorb two pressure balance lateral mode expansion joints simultaneously to displacement.Low pressure, bore are big, the non-dusting occasion of medium but present pressure balance lateral mode expansion joint is only applicable to, and can't satisfy medium is the small-bore high pressure line requirement of dust granules.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned deficiency at prior art, and it is the anti-build pressure balanced transversal type expansion joint of outer drawing type high pressure on the small-bore high pressure line of powder method particle that a kind of medium that is applicable to is provided.
The technical solution adopted in the utility model is as follows:
A kind of outer drawing type high pressure is prevented build pressure balanced transversal type expansion joint, it is characterized in that it includes the work bellows component that is installed in the adapter assembly outside, one end of work bellows component links to each other with an end of balance bellows component, the other end of balance bellows component links to each other with an end of another section work bellows component, shell ring in the middle of the other end of this section work bellows component is connected to, establish one group of work bellows component in addition between middle shell ring right side and the adapter assembly, two groups of work bellows components and the combination of middle shell ring absorb lateral displacement, above-mentioned two overlaps of taking over assembly are installed the flexible sealing assembly, the top sweep module is located at the end of the medium inlet direction of above-mentioned another section work bellows component, middle sweep module is located at the balance bellows component end of medium inlet direction, also be provided with two groups of pull bars in the outside of bellows, the blind plate power of bellows reaches balance by the connection of these two groups of pull bars.。
Described adapter assembly is provided with oblique outlet.
The outside, two ends of above-mentioned one group of pull bar is equipped with taper faced washer, and the outside of taper faced washer is equipped with Ball faced nut, and the outside of Ball faced nut is equipped with locking nut, and two nuts are respectively established in another outside, group pull bar two ends.
The beneficial effects of the utility model have:
The utility model is specially adapted to modern oil, chemical industry (especially domestic flourish Coal Chemical Industry industry) two equipment room media are the small-bore high pressure line of dust granules, in expansion displacement, also absorb the lateral expansion displacement at absorption axes, and counter-force and moment are little.The combination of two groups of whirlwind sweep module and oblique outlet can prevent effectively that the dust granules in the medium from entering bellows interior, keeps inner no any particle to gather.The overlap of last lower linking tube assembly is installed flexible sealing structure, can guarantee freely stretching of expansion joint when the dust granules in stoping medium enters bellows interior.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model work bellows component 1 is installed in takes over assembly 4 outsides, the right-hand member of work bellows component 1 links to each other with the left end of balance bellows component 2, the right-hand member of balance bellows component 2 links to each other with the left end of work bellows component 3, the useful area of bellows is the twice of work bellows component 1,3 in the balance bellows component 2, and the useful area of work bellows component 1 and 3 equates.Shell ring 6 in the middle of the right-hand member of work bellows component 3 is connected to is established 3, two groups of work bellows components of one group of work bellows component 3 in addition and is absorbed lateral displacement with middle shell ring 6 combinations between middle shell ring 6 right sides and the adapter assembly 5.
The utility model is taken over assembly 4 and with the overlap of taking over assembly 5 flexible sealing assembly 9 is installed, and can guarantee freely stretching of expansion joint when the dust granules in stoping medium enters bellows interior.Top sweep module 8 is located at work bellows component 3 ends of medium inlet direction; middle sweep module 7 is located at balance bellows component 2 ends of medium inlet direction; forming effective whirlwind purges; prevent that the dust granules in the medium from entering bellows interior; and on adapter assembly 4, be provided with oblique outlet, can guarantee that inner no any particle gathers.Also be provided with pull bar 10 and pull bar 11 in the outside of bellows, the blind plate power of bellows reaches balance by the connection of pull bar 10,11.
The utility model pull bar 10 ends are equipped with taper faced washer 13, and the outside of taper faced washer 13 is equipped with Ball faced nut 14, and the outside of Ball faced nut 14 is equipped with locking nut 15, solve the lateral displacement of expansion joint by the rotation of taper faced washer 13 and Ball faced nut 14.Two nuts 12 are respectively established in another outside, group pull bar 11 two ends.The structure that the utility model also also adopts multilayer to add stabilizing ring at bellows is born the high pressure of system, and has reduced rigidity to greatest extent.
Other undeclared part of the utility model is same as the prior art.
