Abstract
The utility model relates to a flexible telescopic device for pipeline, comprising a main body of the telescopic device, a rubber sealing ring and a telescopic pipe; the main body of the telescopic device is of reduced double-flange structure, and the rubber sealing ring is impacted on the main body of the telescopic device by a flange pressure disc; the telescopic pipe penetrates through the flange pressure disc, extends into the main body of the telescopic device, and is tightly clamped by the rubber sealing ring. The utility model has the advantages that the main body of the telescopic device and the telescopic pipe can be rotated opposite to each other, the flexible telescopic device for pipeline can extend and contract in axial direction, and the bend in radial direction can be up to 11 DEG; no leakage can be guaranteed in the pressure of 25 kilograms per square centimeter.
Description
The utility model is a kind of pipeline flexible expansion bend.The flexible stretchability that mainly is applicable to conveyance conduit joints such as feedwater, blowdown, coal gas, oil liquifier connects.
At present, pipeline connects main by (one) common movable joint, (two) free flow coupling, and (three) have flexible but do not have flexible expansion bend.They have following shortcoming respectively: (one) common movable joint, do not possess telescopicing performance, and (two) free flow coupling can not be dismantled after the installation, can only work the effect of being fixedly connected.(3) the common pipe expansion bend do not have flexibility can not be crooked, not anticorrosive.If make of copper material and aluminum alloy material, then improved cost etc. greatly.
The design the purpose of this utility model, just be to provide a kind of pipeline flexible joiner with the above three kinds of pipe joint advantage, connect with flexible with the flexibility that guarantees piping erection, make it easy for installation, use flexibly, the life-span is long and antidetonation again the pipeline of no seepage and no leakage connect requirement.
Figure of description is a structural drawing of the present utility model, among the figure: the 1st, telescopic pipe, the 2nd, nut, the 3rd, flange gland, the 4th, rubber seal, the 5th, bolt, the 6th, expansion bend body.
As shown in the figure, the flexible telescopic coupling for pipe that provides of the utility model is made up of telescoping tube (1), bolt (5), nut (2), flange gland (3), rubber seal (4), expansion bend body (6) six parts. Expansion bend body (6) and flange gland (3) The centre accompanies sealing rubber ring (4). Connect by bolt (5), nut (2), telescoping tube (1) clamps sealing by flange gland (3) by rubber ring (4), places in the expansion bend body (6).
Telescopic pipe (1), flange gland (3), expansion bend body (6) all can be selected HT200 or KT33-8 material for use, form through cutting.
Rubber seal can select for use neoprene to make.
Telescopic pipe (1) is the flange tubulose, on 4～12 screws that connect with Outer Tube are arranged, main effect is to regulate expansion bend length, to satisfy its use and installation requirement.
Acting as with expansion bend body (6) of flange gland (3) connects, and compresses sealing rubber ring (4) and adjusts the flexibility of expansion bend.Have on the flange plate with expansion bend body (6) and connect screw accordingly.Rubber seal (4) is clipped in the middle of expansion bend body and the flange gland, cushion rubber endoporus and telescopic pipe outer tube wall compress, the expansion bend body adopts the two flange arrangements of reducing, and path is all nominal diameter mutually with the telescopic pipe internal diameter, greatly directly greater than the expansion bend outer tube diameter to satisfy the requirement of soft readjustment scope.
For satisfying the soft readjustment requirement, the mesopore of flange gland (3) is made bell mouth shape in the utility model, and for identical reason, expansion bend body (6) larger diameter end flange-interface place can process bigger chamfering.
The utility model has the advantages that: simple in structure, easy to install, concentrated the advantage of articulated joint, straight connector and common expansion bend in the prior art, cooperate with the expansion bend body by telescopic pipe and can finish flexible, rotation and 11 °, and guarantee at 25kg/cm with three kinds of adjustment tasks of interior bending
2No seepage and no leakage under the pressure.
Claims (2)
1, a kind of pipeline flexible expansion bend, comprise telescopic pipe, expansion bend body and rubber seal, it is characterized in that: the expansion bend body is the two flange arrangements of reducing, rubber seal is clamped in the larger diameter end of expansion bend body through a flange platen, and telescopic pipe passes the flange platen and places the expansion bend body and clamped by rubber seal.
2, pipeline flexible expansion bend according to claim 1, it is characterized in that: the mesopore of flange platen is bell mouth shape.
