Abstract

The invention relates to a connecting method for arched steel bands and gas pipes. The connecting method includes: firstly manufacturing rubber pipe flange casings with inner diameter faces corresponding to outer helix convex and concave faces of two pipes, respectively inserting two opposite pipe ends of two pipe sections into metal flanges, helically sleeving the metal flanges into the rubber pipe flange casings, implanting a sealing rubber ring between two pipe connecting ends, and connectively fixing the metal flanges at two ends, namely completing connecting of two pipe sections. The connecting method for arched steel bands and gas pipes has the advantages that metal flange welding procedure is omitted, connecting requirement of helical welding of the steel bands and the gas pipes can be met, the structure is simple, connecting is safe and reliable, transport and using are convenient, and under-coalmine mounting and operating are facilitated.

Description

A kind of connecting means of arch ribbon spiral welding gas tube
Affiliated technical field
The present invention relates to spiral welding steel band gas pipe, be specially a kind of connecting means of spiral welding arch steel band gas tube, be applicable to the connection of underground mine use spiral welding steel band gas tube.
Background technique
At present, the connecting means of known spiral welding steel band gas tube is at pipe end weld metal flange plate or process plastics flange and connect, and the problem of existence is complex procedures, because pipe end has flange, transportation, stores and makes troubles.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of connecting means that is exclusively used in spiral welding steel band gas tube is provided, do not need welded flange in advance, can save operation, pipeline and link can store respectively and transport, easy construction.
The technological scheme that technical solution problem of the present invention adopts is: a kind of connecting means of spiral welding arch steel band gas tube, make a kind of aperture surface rubber pipe flange cover corresponding with body external spiral male and female face earlier, this rubber pipe flange overlaps the flange rib that there is the radially outward expansion end, tapered from large to small from flange rib rubber pipe flange cover external diameter backward, need the body end of butt joint to be inserted in the metal flange dish respectively to two joints, spiral is inserted in rubber pipe flange cover again, put into O-ring seal between the two body connecting ports, the metal flange dish with two ends is connected and fixed the connection of namely finishing the 2-section pipe body again.
Described metal flange dish internal diameter greater than the outer diameter of rubber pipe flange cover tapering small end less than the external diameter of the big end of tapering.
Described metal flange dish is connected to bolt and connects.
During connection, earlier the metal flange dish is enclosed within on the pipeline body, again rubber pipe flange cover is screwed on the body end face along body spiral prominence concave surface.Utilize bolt that the two pipeline bodys that have rubber pipe flange cover are linked together.Because of circle undersized in the metal flange dish in the big end size of rubber pipe flange cover tapering, after the connection, rubber pipe flange cover endoporus can realize dwindling under the effect of metal flange dish and the tubing cylindrical between sealing.
The invention has the beneficial effects as follows, saved metal flange dish welding process, can satisfy the connection request of spiral welding steel band gas tube, simple in structure, connect safe and reliablely, be convenient to transport, easy to use, be convenient to fitting operation under the mine.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the cross-sectional schematic of Placement structure of the present invention.
Fig. 2 is metal flange dish structural representation in the Placement of the present invention.
1. bodys among the figure, 2. rubber pipe flange cover, 3. connecting bolt, 4. plain cushion, 5. metal flange dish, 6. nut, 7. O-ring seal.
Specifically execute real mode
Embodiment: in Fig. 1, earlier metal flange dish 5 is set on the outer surface of spiral welding arch steel band gas tube 1, the rubber pipe flange being overlapped the spiral concave surface of 2 internal surfaces and the convex surface of spiral welding steel band gas tube 1 outer surface spins together again, between two tube end faces, add sealer circle 7, utilize connecting bolt 3, plain cushion 4 and nut 6 that two tubing are linked together.
It is a tapering face that the rubber pipe flange overlaps 2 outer surfaces, the interior round size of metal flange dish 5 is overlapped the big end of the 2 appearance conical surfaces less than the rubber pipe flange, when by external force metal flange dish 5 being shifted onto the rubber pipe flange and overlaps the big end place of the 2 appearance conical surfaces, make the rubber pipe flange overlap 2 endoporus size decreases, be pressed in tightly on spiral welding steel band gas tube 1 outer surface, reach sealing effect between the two.
Hole dimension is determined according to the size that the rubber pipe flange overlaps the 2 appearance conical surfaces in the metal flange dish 5.Greater than the size of conical surface small end, less than the size of the big end of the conical surface.

Claims (3)
