Abstract
The utility model discloses a flange jamming type connecting pipe fitting which comprises a connecting pipe, connecting flanges, bolts, joint flanges and a structure, wherein the structure is that inner holes of the joint flanges are equal to the inner diameter of the connecting pipe; the outside of the connecting pipe is protruded into a trapezoidal surface of the connecting pipe; the bolts are connected with the connecting flanges and the joint flanges; the connecting flanges contact one side of the trapezoidal surface of the connecting pipe; the other side of the trapezoidal surface of the connecting pipe contacts with a sealing gasket. Thereby, the utility model has the advantage of convenient connection and operation; the work efficiency is enhanced; the utility model puts an end to the defects that adhesive joints are infirm, and the inner diameter is reduced by the inner fovea; the utility model ensures that the connecting pipe with the pipe diameter more than phi 60MM is firmly sealed; the utility model puts an end to the phenomenon of dripping; the utility model which ensures the normal running of pipelines enlarges the application range.
Description
One, technical field:
A kind of flange card convex type connecting pipe of the utility model relates to plumbing pipe and pipeline connecting pipe fitting technical field thereof, is applied to copper pipe, thin-wall stainless steel, stainless steel-plastic composite pipe.
Two, background technique:
At present, the water of being supplied on the market, the hot-water heating pipe adopts traditional galvanized pipe substantially, the pipeline of copper tube, its Placement is continued to use the outer silk of pipeline processing, no matter straight joint, elbow, pipe joints such as threeway, all should connect with pipe joint with internal thread, very easy oxide etch, influenced actual working life, polluted water, aluminium-plastic composite pipe can overcome and reduce water pollution, though using bayonet connection can carry out pipeline connects, owing to very easily intensity being lost in the aluminium skin corrosion of centre in water oxygenization, cause plastic-aluminum combined tracheal rupture, leak, again because aluminium-plastic composite pipe is caught a cold by heat expansion to contract easily, time one is of a specified duration, influenced the sealing of bayonet connection, the water leakage phenomenon that is caused happens occasionally, and has influenced applying of aluminium-plastic composite pipe, and what then come is to substitute above-mentioned three kinds of pipeline materials with stainless steel-plastic composite pipe, but, 1-adopts bonding method that pipeline and pipe joint are bonded together, and relates to adhesion technique requirement height, and bonding fastness varies with each individual, relatively lack technical support, be difficult to use in field boundary and close with uniform temperature; 2-adopts at the pipeline material jointing and adds being connected and sealed of pipeline connecting pipe fitting with the method for indent, the problem that takes place is to be cost to sacrifice internal diameter of the pipeline, and connection relative complex, adopt the mode of connecting tube evagination, for connecting tube, if adopt the sealing of nut roof pressure greater than Φ 60mm caliber, exist because pipeline section is long-pending relatively large, the pressure that bears relatively is big, causes the phenomenon of water clock easily, is difficult to guarantee the defective of the normal operation of pipeline.
Three, summary of the invention:
The purpose of a kind of flange card convex type connecting pipe of the utility model is the structure of inverter tube pipe connecting, and it is firm to reach long-time connection.Its technology is achieved in that the structure that comprises that connecting tube, adpting flange, bolt, joint flange, joint flange endoporus equate with the connecting tube internal diameter, it is characterized in that: the connecting tube evagination becomes the connecting tube trapezoidal faces, bolt connects adpting flange, joint flange, adpting flange conflict connecting tube trapezoidal faces one side, connecting tube trapezoidal faces opposite side conflict gasket seal, described pipe connector lug trapezoidal faces is identical with the end shape that above-mentioned connecting tube evagination becomes the connecting tube trapezoidal faces to offset.Its tangible advantage is that easy to connect, operation is convenient, has improved work efficiency, stopped the defective that bonding not firm and indent reduces internal diameter, guaranteed the connecting tube greater than Φ 60mm caliber, it is firm to seal, stop the phenomenon of water clock, guaranteed the normal operation of pipeline, enlarged application area.
Four, description of drawings:
Fig. 1 is the structural representation that direct first end connects the embodiment of connecting tube;
Wherein, 1-joint flange, 2-gasket seal, 3-adpting flange, 4-bolt, 5-connecting tube, 6-connecting tube trapezoidal faces;
Five, embodiment:
Be further described with direct first end and being connected of connecting tube below in conjunction with accompanying drawing:
See accompanying drawing 1, connecting tube (5) is inserted in the connecting tube (5) that adpting flange (3) back evagination becomes connecting tube trapezoidal faces (6), stretch into joint flange (1), adpting flange (3) one end conflict connecting tube trapezoidal faces (6) one sides, connecting tube trapezoidal faces (6) opposite side conflict gasket seal (2), gasket seal (2) opposite side conflict joint flange (1), bolt (4) connects adpting flange (3), joint flange (1).
See accompanying drawing 1, intercepting connecting tube (5) length, be inserted in two adpting flanges (3) respectively, expand the connecting tube trapezoidal faces (6) that two end evaginations with the expanding device, two adpting flanges (3) between the connecting tube trapezoidal faces (6) of connecting tube (5) two end evaginations can't be deviate from, connecting tube (5) stretches into joint flange (1), adpting flange (3) one end conflict connecting tube trapezoidal faces (6) one sides, connecting tube trapezoidal faces (6) opposite side conflict gasket seal (2), connect adpting flange (3) by bolt (3), joint flange (1) also screws, and compresses gasket seal (2) by connecting tube trapezoidal faces (6) and seals.
Whole piping, according to configuration, the joint flange of pipeline (1), profile can be different, but the joint flange that the endoporus functional structure is identical (1) has straight joint, 90 ° of elbows, equal tee joint, reducing T, 45 ° of elbow connections, the elbow connection etc. of riding, and the technology of connection is identical with above-mentioned process.
Claims (3)
1. flange card convex type connecting pipe, comprise connecting tube (5), adpting flange (3), bolt (4), joint flange (1), joint flange (1) endoporus equates in interior structure with connecting tube (5) internal diameter, it is characterized in that: connecting tube (5) evagination becomes connecting tube trapezoidal faces (6), adpting flange (3) conflict connecting tube trapezoidal faces (6) one sides, connecting tube trapezoidal faces (6) opposite side conflict gasket seal (2).
2. according to the described a kind of flange card convex type connecting pipe of claim 1, it is characterized in that: described pipe connector lug (3) shape is identical with the end shape that above-mentioned connecting tube (5) evagination becomes connecting tube trapezoidal faces (6) to offset.
3. according to the described a kind of flange card convex type connecting pipe of claim 1, it is characterized in that: bolt (4) connects adpting flange (3), joint flange (1).
