The invention is provided with a concave flange, a convex flange and binding bolts. The concave flange and the convex flange are provided with central pylomes for the conveying pipes to extend into; the concave flange is connected with the convex flange by the binding bolts. The concave flange can consist of two parts; the concave flange had better consist of two parts; parts of the concave flange are connected by the binding bolts. The convex flange can be formed by two parts; the convex flange had better consist of two parts; parts of the convex flange are connected by the binding bolts.

Description

A kind of flange apparatus that connects delivery pipe
Technical field
The present invention relates to a kind of connection set of delivery pipe, especially relate to a kind of flange apparatus that connects delivery pipe.
Background technique
At present, connection between the delivery pipe generally has three kinds of modes: 1, directly welding: will carry out in the erecting bed when directly welding, generally will carry out trial assembly, welding, removing welding slag, series of processes such as 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, flared fitting etc. are arranged usually, these modes all are 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 shaping round tube flange apparatus for the utility model patent of CN2161798.This device is made up of a pair of annular flange, a lock uint and an airtight pad.On annular flange, be provided with,, be provided with containing groove, utilize the extension annular lamina of containing groove leading edge will extend annular lamina and the various forms that knot of circular duct ora terminalis machine shaping by facility in the annular flange lower end so that annular flange is connected with binding block in conjunction with otch; The oblique angle of being made up of two annular flange upper inclined surface is in the reversed V-shape ring of lock uint, is convenient to assembly two airducts; Add the airtight pad that is between two annular flanges and can prevent effectively that air-flow from leaking, and engage firmly.
Notification number provides a kind of FERRULETYPE fast-assembling piping flange for the utility model patent of CN2466472, form by flange cover dish, pressure ring, collar, seal ring, flange cover dish is enclosed within on the pipe, carve several roads groove in the pipe termination, collar is put into the pipe groove, the two halves pressure ring closes, the pressure ring inboard wall groove is dropped on the collar, to push away before the flange cover dish, be inserted in the two halves pressure ring and combine and put in place, seal ring is inserted in pipe end, connect another flange plate with bolt with pressure ring, fix in the pipe termination, therefore quick and easy for installation.
Summary of the invention
The flange apparatus that the purpose of this invention is to provide the connection delivery pipe that a kind of dismounting is fast convenient, simple in structure, cost is low.
The present invention is provided with spill flange, convex flange and clamping bolt.Spill flange and convex flange are equipped with the central through bore that stretches into for delivery pipe, connect by clamping bolt between spill flange and the convex flange.
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.
Spill flange and convex flange can be metal concave flange and metal convex flange, also can be nonmetal spill flange and nonmetal convex flange, or the compound spill flange of metal and nonmetallic material and compound convex flange.
During practical application, delivery pipe can be straight-through tube or curved siphunculus, also can be pipe joint, as straight-through, threeway, cross fitting, 90 ° of elbows and 45 ° of elbows etc.
During use, spill flange and convex flange are enclosed within respectively on the port of connected 2 delivery pipes, and are welded in the port of delivery pipe, but preferably earlier with delivery pipe port flange, flange is movable to be enclosed within the delivery pipe end, and is pressed on the flange back side.Only need mix seal ring between the port of 2 delivery pipes, the connection by clamping bolt gets final product.During dismounting, no matter be the integral type flange, still split type flange need only unclamp clamping bolt and get final product.So dismounting ten minutes quick and convenient, and flange arrangement is simple, and fabricating cost is low.In addition, when clamping bolt is fastening when putting in place, the flange port of connected 2 delivery pipes all is positioned at the groove of spill flange, makes the flange port be subjected to more effective protection, avoids damaged, thereby also can make sealability better.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the spill flange arrangement schematic representation of the embodiment of the invention.
Fig. 3 is the convex flange arrangement schematic representation of the embodiment of the invention.
Fig. 4 is an embodiment of the invention user mode structural representation.
Embodiment
Referring to Fig. 1~4, the present invention is provided with spill flange 1, convex flange 2, clamping bolt 3 and seal ring 4.Spill flange 1 and convex flange 2 are equipped with the central through bore that stretches into for delivery pipe 5 and 6, connect by clamping bolt 3 between spill flange 1 and the convex flange 2.Convex flange 2 is an integral type, and spill flange 1 is split type, and spill flange 1 is made of the first half 11 and Lower Half 12.During use, the first half 11 of spill flange 1 and Lower Half 12 are superimposed by bolt ear 111 and 121, and 3 companies of wearing get final product through clamping bolt.Bolt hole in each bolt ear of spill flange 1, convex flange 2 and clamping bolt 3 is provided with internal thread.
During use, spill flange 1 and convex flange 2 are enclosed within respectively on the end of connected 2 delivery pipes 5 and 6, elder generation is with the port flange of delivery pipe 5 and 6, again spill flange 1 and convex flange 2 are enclosed within the end of delivery pipe 5 and 6 respectively, and be pressed on the flange back side, the last seal ring 4 of mixing between the end face of 2 delivery pipes gets final product by clamping bolt 3 connections.During dismounting, no matter be the integral type flange, still split type flange need only unclamp clamping bolt 3 and get final product.When clamping bolt 3 fastening putting in place, the flange of connected 2 delivery pipe ports all is positioned at the groove of spill flange 1, makes the flange of port be subjected to more effective protection, avoids damaged, and sealability is better.
The convex flange also can adopt split type, and the spill flange adopts integral type; Spill flange and convex flange also can adopt split type simultaneously or adopt integral type simultaneously.

Claims (2)

1. a flange apparatus that connects delivery pipe is characterized in that being provided with spill flange, convex flange and clamping bolt, and spill flange and convex flange are equipped with the central through bore that stretches into for delivery pipe, connect by clamping bolt between spill flange and the convex flange; The convex flange is made up of at least 2 parts, connects by clamping bolt between the convex flange each several part.
2. a kind of flange apparatus that connects delivery pipe as claimed in claim 1 is characterized in that the convex flange is made up of 2 parts.
