Abstract
The invention discloses a novel detachable sleeve comprising inner connecting pipes and outer sleeves, wherein the inner connecting pipes are sleeved in the outer sleeves. The novel detachable sleeve further comprises pressing cover flanges, middle flanges, flanges, asbestos packings and supporting blocks, wherein the pressing cover flanges are fixedly connected to the outer walls of the inner connecting pipes; the flanges are fixedly connected with the outer walls of the outer sleeves; and the middle flanges are mounted between the inner connecting pipes and the outer sleeves. According to the novel detachable sleeve, the flanges are additionally arranged on the basis of a previous sleeve structure, so that a detachable structure is formed; the inner connecting pipes are convenient to replace; when the inner connecting pipes are abandoned, the outer sleeves can be continually used, so that the production cost is saved; the asbestos packings are filled between the middle flanges and the inner connecting pipes, so that the sealing performances of the sleeves are effectively enhanced and the application of the novel detachable sleeve in a high-pressure field is added; and the supporting blocks are additionally arranged so that the rigidity of the inner connecting pipes is improved, the vibration can be effectively prevented, and the damage to the sleeves, caused by vibration, is avoided.
Description
Technical field
The invention belongs to the pipe joint technical field, be specifically related to a kind of removable sleeve pipe.
Background technique
The application of sleeve pipe on the industry equipment such as chemical industry, medicine, food is very extensive, and for satisfying every profession and trade to the user demand of sleeve pipe, existing sleeve pipe is of a great variety, and structure is not quite similar, and the sleeve pipe that some are simple in structure often can only be confined to specific use occasion; And the wider sleeve pipe of some using scope then exists complex structure, the poor problem of sealing effect, has not only increased manufacture cost, uses also inconvenience is installed, and installation efficient is low.And often there is vibration problem in existing sleeve pipe, and this problem has been accelerated the damage of sleeve pipe, has reduced the working life of sleeve pipe.
Summary of the invention
The above-mentioned technical problem that exists in order to overcome the prior art field the object of the invention is to, and a kind of New removable sleeve pipe is provided, and is simple in structure, and installation efficiency is high, is convenient to change.
New removable sleeve pipe provided by the invention, comprise inner connecting tube and outer sleeve, inner connecting tube is sleeved in the outer sleeve, it also comprises gland flange, spacer flanger, flange, asbestos packing and support block, described gland flange is fixedly connected on the inner connecting tube outer wall, flange is fixedly connected on the outer sleeve outer wall, and spacer flanger is installed between inner connecting tube and the outer sleeve.Described spacer flanger is fixedly connected with flange by bolt, is fastenedly connected by fastening piece and gland flange.Be filled with asbestos packing between described spacer flanger and the inner connecting tube.Described support block is fixedly connected on the inwall of outer sleeve.
New removable sleeve pipe provided by the invention, its beneficial effect is: increase flange on original sleeve structure basis, make it become dismountable structure, be convenient to change inner connecting tube, inner connecting tube is scrapped, and outer sleeve can continue to use, and has saved cost of production; Between spacer flanger and inner connecting tube, fill asbestos packing, effectively strengthened the sealability of sleeve pipe, increased its application in the high pressure occasion; The extension supporting piece has not only improved the rigidity of inner connecting tube, can also effectively prevent vibration, avoids vibrating the casing failure that causes.
Description of drawings
Fig. 1 is the overall structure schematic representation of one embodiment of the invention.
Mark among the figure:
1. fastening piece; 2. gland flange; 3. spacer flanger; 4. flange; 5. asbestos packing; 6. inner connecting tube; 7. outer sleeve; 8. support block; 9. bolt.
Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, New removable sleeve pipe provided by the invention is described in detail.
Embodiment
With reference to Fig. 1, the New removable sleeve pipe of present embodiment comprises inner connecting tube 6 and outer sleeve 7, inner connecting tube 6 is sleeved in the outer sleeve 7, it also comprises gland flange 2, spacer flanger 3, flange 4, asbestos packing 5 and support block 8, described gland flange 2 is fixedly connected on the inner connecting tube outer wall, flange 4 is fixedly connected on the outer sleeve outer wall, and spacer flanger 3 is installed between inner connecting tube 6 and the outer sleeve 7.Described spacer flanger 3 is fixedly connected with flange 4 by bolt 9, is fastenedly connected by fastening piece 1 and gland flange 2.Be filled with asbestos packing 5 between described spacer flanger 3 and the inner connecting tube 6.Described support block 8 is fixedly connected on the inwall of outer sleeve 7.
The New removable sleeve pipe, during manufacturing, first with flange welding sleeve outer wall upper end outside, then support block is welded on the outer sleeve lower inner wall, after being welded on gland flange on the inner connecting tube outer wall, fill asbestos packing, spacer flanger is installed between inner connecting tube and the outer sleeve at last, and make spacer flanger and asbestos packing fastening by fastening piece, by bolt flange and spacer flanger are fastenedly connected.Inner connecting tube is scrapped, and dismountable flange is changed inner connecting tube, and outer sleeve can continue to use, and has reduced cost of production.Weld support block on the outer sleeve lower inner wall, not only improved the rigidity of inner connecting tube, also effectively prevented vibration, avoid vibrating the casing failure that causes, prolonged the working life of sleeve pipe.Fill asbestos packing, effectively strengthened the sealability of sleeve pipe, make it can not only be applied to common occasion, can also be applied to the high pressure occasion.
Above-mentioned explanation only be for clearly demonstrate that the present invention does for example, be not to be restriction to embodiment of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Everyly belong to the row that apparent variation that technological scheme of the present invention amplifies out or change still are in protection scope of the present invention.
