Abstract

The utility model provides a welded corrugated pipe special for a freezing and drying device and belongs to the technical field of pipeline connection. The welded corrugated pipe comprises corrugated pipe bodies, a first flange and a second flange, wherein the first flange and the second flange are connected with two ends of each corrugated pipe body, and a spacer ring is arranged between the corrugated pipe bodies. The spacer ring is of an annular pad structure, and the periphery portion of the spacer ring is slightly thicker than the inside. The welded corrugated pipe is simple in manufacture, low in cost and high in efficiency, and the service life is prolonged greatly. The welded corrugated pipe has adverse factors including complicated manufacture process, multiple manufacturing steps, high manufacturing cost, low efficiency and the like. The shortcoming that formed corrugated pipes (wave trough cross sections of the corrugated pipes are semi-circular) manufactured in the prior art is overcome, and the problem that the welded corrugated pipe is too high in manufacturing cost can be solved. The problems of existing products are solved, the welded corrugated pipe is simple in structure and reasonable in design, and the service life of the welded corrugated pipe can be greatly prolonged.

Description

Freezing, drying equipment special welding bellows
Technical field
The invention belongs to pipeline interconnection technique field, particularly relate to a kind of freezing, drying equipment special welding bellows.
Background technique
Existing bellows is for the connection of various device and pipeline, and application is general, for bellows dry, refrigeration equipment, mostly has one. and amount of bow is not enough, two. and extending amount is little, three. and the problems such as the little and poor in flexibility of extent of the error, can not guarantee its usage requirement.And, there are strict status requirement and structural limitations in space that when mounted need be enough to the device being attached thereto.Caused and needed, with the increase of equipment machine volume and complex structure etc., both to have increased whole set equipment to manufacture complexity and cost, strengthened again usage space, and can not guarantee sealing effect and working life completely.
Summary of the invention
For the technical problem of above-mentioned existence, the invention provides a kind of amount of bow foot, extending amount is large, extent of the error is wide and can universal adjustment assembly position etc. the moulding bellows of feature.It can guarantee usage requirement in any occasion, and the advantage such as can guarantee again good sealing effect, make greatly to extend in working life of bellows has solved the problem that existing product exists.
The object of the invention is to be achieved through the following technical solutions:
Freezing, a drying equipment special welding bellows, comprise first, second flange that bellows and two ends connect, and between described bellows, is provided with spacer ring.
Described spacer ring is air ring structure, and its peripheral part is slightly thicker than inside.
Described spacer ring peripheral part near two end part respectively with circular groove.
Described first flange one end, with boss, is connected with bellows, and its boss periphery is with circular groove, and the other end is with the groove coordinating with external piece.
Described second flange one end, with boss, is connected with bellows, and its boss periphery is with circular groove, and the other end is with the groove coordinating with external piece and seal ring connected in star.
On described the second circumference of flange also with the mounting hole coordinating with external piece.
Beneficial effect of the present invention is:
The present invention is simple in structure, reasonable in design, can not only be connected with external piece well, and good airproof performance, installation, convenient disassembly, increased amount of bow, extending amount and pliability thereof, can greatly extend the working life of bellows.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A structural representation of Fig. 1.
In figure: 1. bellows, 2. the first flange, 21. first boss, 22. first grooves, 3. the second flange, 31. second boss, 32. second grooves, 33. annular grooves, 34. mounting holes, 4. spacer ring, 41. inner sleeves, 42. circular grooves.
Embodiment
Below by embodiment and accompanying drawing, the invention will be further described.
Embodiment: as shown in Figure 1 and Figure 2, the present invention includes first, second flange 2,3 that bellows 1 and two ends connect, 1 of described bellows is provided with spacer ring 4.
As shown in Figure 2, described spacer ring 4 is air ring structure, and its peripheral part is slightly thicker than inside.Described spacer ring 4 peripheral parts respectively with circular groove 42, increase toughness near two end part.
As shown in Figure 2, described first flange 2 one end, with the first boss 21, are connected with bellows 1, and its first boss 21 peripheries are with circular groove 42, and the other end is with the first groove 22 coordinating with external piece.
Described second flange 3 one end, with the second boss 31, are connected with bellows 1, and its second boss 31 peripheries are with circular groove 42, and the other end is with the second groove 32 and the seal ring connected in star 33 that coordinate with external piece.On described the second circumference of flange also with the mounting hole 34 coordinating with external piece.
