Abstract
A connecting structure of conveying pipe relates to a connecting structure between conveying pipes. The present invention provides a connecting structure of conveying pipe with convenient and rapid dismantlement, stable and reliable connection, good sealed performance and wide range of application. The invention is provided with two conveying pipes connected, a concave flange, a convex flange, binding bolts and an obturating ring. The ports of two conveying pipes are provided with at least a layer of flanging; the concave flange and the convex flange are respectively sleeved on the outer edge of the ends of two conveying pipes and support on the back of flanging of port of each conveying pipe; the concave flange and the convex flange are connected with the conveying pipes respectively and movably; the circumferences of the concave flange and the convex flange are provided with at least two binding bolts; the obturating ring is arranged between the ports of two conveying pipes.
Description
Technical field
The present invention relates to the linkage structure between a kind of delivery pipe and the delivery pipe.
Background technique
At present, connection between the delivery pipe (comprising straight tube and bend pipe) generally has three kinds of modes: 1, directly welding: will carry out in the erecting bed when directly welding, generally to carry out series of processes such as trial assembly, welding, removing welding slag and pickling, back dismounting inconvenience is installed, and welding quality is difficult for checking.2, pipe joint connects: generally be applicable to the delivery pipe of minor diameter, Welded fitting, Bite type fittings and flared fitting etc. are arranged usually, above-mentioned Placement all is by being threaded of making on fittings body and the tubing, the precision prescribed height, the assembly technology complexity, easy damaged tubing, cost height.3, flange connects: reliable operation, mounting or dismounting are convenient, but often will weld out or cast out flange at the port of delivery pipe, make the required precision height, increase cost.
Notification number provides a kind of connection set of slurry delivery pipe for the model utility of CN2605451, it be by two be arranged in parallel and internal diameter be conical pressing plate, two groups of taper voussoirs being complementary with the pressing plate internal diameter, be loaded on bolt on the two parallel pressing plates and back-up ring, O shape circle, support ring constitutes, have simple, reliable, convenient, practical advantage, can reach the double effects that connects and seal.
Summary of the invention
The purpose of this invention is to provide convenient quick, the linkage structure that connects reliable and stable, good seal performance, delivery pipe applied widely of a kind of dismounting.
The present invention is made of connected 2 delivery pipes, spill flange, convex flange, clamping bolt and seal ring.The port of 2 delivery pipes is equipped with at least 1 layer of flange; Spill flange, convex flange are enclosed within respectively on the outer, 2 delivery pipe ends, and be resisted against on the port flange back side of delivery pipe separately, spill flange and convex flange constitute flexible connection with delivery pipe respectively, circumference at spill flange and convex flange is provided with at least 2 clamping bolts, is provided with seal ring between the port of 2 delivery pipes.
The spill flange can be made up of at least 2 parts, and the spill flange preferably is made up of 2 parts, connects by clamping bolt between the spill flange each several part.
The convex flange can be made up of at least 2 parts, and the convex flange preferably is made up of 2 parts, connects by clamping bolt between the convex flange each several part.
Delivery pipe can be straight-through tube or curved siphunculus or pipe joint.Pipe joint can be straight coupling, union, tee union, cross fitting, 90 degree elbows, one eighth bend etc.
The angle of flange is preferably 90 ° less than 180 °.Be can be orthogonal between the flange of delivery pipe and the tube wall, also can become other angle, certainly the angle of the end of delivery pipe also corresponding the variation.
Delivery pipe port flange is at least 1 layer of flange.Flange is preferably the individual layer flange, double flare or 3 layers of flange, and the individual layer flange is 1 font, and double flare is the shape of falling ∪, and 3 layers of flange are ∽ shape.
Delivery pipe can be metalwork, also can be non-metal part, or the composite members of metal and nonmetallic material.
Because the present invention is provided with movable flange, mutually nested with the convex flange and axially fasten by clamping bolt and to be connected by the spill flange, can be according to the different requirements of delivery pipe material, bore, purposes, the port of delivery pipe can be set as individual layer, bilayer or multilayer flange, compressive strength, sealing are met the demands, so the present invention have and connect outstanding advantage and effects such as efficient and convenient, solid and reliable, working stability, good seal performance, simple in structure and cost cost are low.

Fig. 1 is the structural representation of the embodiment of the invention 1.
Fig. 2 is the convex flange arrangement schematic representation of the embodiment of the invention 1.
Fig. 3 is the spill flange arrangement schematic representation of the embodiment of the invention 1.
Fig. 4 is the structural representation of the embodiment of the invention 2.
Embodiment
Referring to Fig. 1～3, the present invention is made of 2 delivery pipes 1 and 2, convex flange 3,4,4 clamping bolts 5 of spill flange and seal ring 6.Convex flange 3 and spill flange 4 are enclosed within respectively on the outer, end of delivery pipe 1 and 2, and are resisted against on delivery pipe 1 and 2 port flange 11 and 21.Flange 11 is the individual layer flange, and flange 21 is a double flare.Between the port of 2 delivery pipes 1 and 2, be provided with seal ring 6.
Convex flange 3 is the integral type flange, and spill flange 4 is divided into the first half 41 and Lower Half 42.During use, the first half 41 and Lower Half 42 are superimposed by bolt ear 411 and 412, pass through clamping bolt 5 to get final product.
The convex flange also can be split type, and the spill flange is an integral type; Convex flange and spill flange also can be integral type, also can be split type.When being split type, can adopt 2 parts or many parts.Such flange Connecting format can realize fast, dismounting easily, good sealing effect.
Referring to Fig. 4, similar to Example 1, its difference is that 1 in 2 delivery pipes is a straight tube 2 for 7,1 of bend pipes.In Fig. 4, other code name 3～6 is identical with Fig. 1.
Bend pipe among Fig. 4 also can adopt pipe joint.
