Abstract
The utility model discloses a pipeline connecting device which belongs to the technical field of pipeline connection and is composed of a connecting sleeve 1 with circumference sealing grooves and circumference locking grooves. The utility model is characterized in that the inner diameter of the interface end of the connecting sleeve 1 is larger than that of the middle part of the connecting sleeve 1; the circumference sealing grooves and the circumference locking grooves are respectively positioned the middle part and the interface part of the inner wall of the connecting sleeve 1; a clamping spring is arranged in each of the locking grooves; the inner side of each of the clamping spring is provided with a cushion ring 3 composed of two half circles. The utility model has the characteristics of high speed, connection and disassembly, and favorable sealing performance, firm and reliable connection and is an ideal connecting device for plastic pipes, non-ferrous metal pipes, and general material pipes.
Description
The utility model relates to a kind of pipeline connecting device, metal conduit connection technique field.
Existing pipeline connecting device mainly contains 1, scyewed joint, 2, flange connects, and 3, welding, 4, bonding, 5, the structure attached method, preceding four kinds of methods, the technical requirements height, engineering work load is big, the raw material consumption is big, particularly, the connection of high pressure pipe line and non-ferrous metal by national technical management requirement, must be accredited welder's welding, the postwelding perspective of also will detecting a flaw, after the passed examination, could use the 5th kind of connecting mode---socket, it is a kind of pipeline connection technique that grew up in recent years, it is fast to have connection speed, and good airproof performance is economized characteristics such as material, as the patent No. is 95234047.7, but because of the coupling arrangement of this structure, requiring projection on the coupled pipe is N (N 〉=2), when this coupling arrangement and coupled pipe combine as a whole, pressure all concentrates on N the projection, if pipe is a plastic materials, projection easily comes off, and causes the connection sealing not firm; When tubing is nonferrous metal tube (as copper, aluminium), also there is this situation, both influenced to mould the speed of Dai Gang, cause the waste of metallic material and the raising of cost.Simultaneously, the connecting mode of nonferrous materials is restricted.Secondly, it is big and be difficult for bonding characteristics that vinyl tube has toughness, during scyewed joint, can not bear pressure, limited using scope, though igelite hardness is bigger, easily bonding, toughness is relatively poor, frangible, shorten working life, and cost is high 1/3 times than polyethylene.
The purpose of this utility model is, provides a kind of and makes that pipe connects, sealing is convenient, solid and reliable, and the connection of the common metal pipe that can suit, the pipeline connecting device that suitable especially again plastic tube, nonferrous metal tube connect,
Technical solution of the present utility model is, it is made up of the joint sleeve 1 with two interfaces at least, each interface of joint sleeve 1, at least a circumferential seal groove and a circumference locking slot on the corresponding joint sleeve inwall, be characterized in, the internal diameter of joint sleeve 1 interface end is greater than the internal diameter of joint sleeve 1 intermediate portion, circumferential seal groove is positioned on the internal diameter of joint sleeve 1 intermediate portion, locking slot is positioned on the internal diameter of joint sleeve 1 interface end, in each locking slot, establish a notched jump ring 2, be provided with packing ring 3 in the space of each jump ring 2 inboard, packing ring 3 is made up of two semicircles.
The interface of the joint sleeve 1 of this pipeline connecting device can be 2, also can be 3,4.When the interface of joint sleeve 1 is 2, and two interfaces have just formed a kind of pipe box coupling that connects straight tube when being positioned on the same axis; When the interface of joint sleeve 1 is 2, and two interfaces have just formed a kind of elbow coupling that connects mutual vertical tube when vertical mutually.When the interface of joint sleeve 1 is 3, wherein two are positioned on the same axis, the 3rd be positioned at same axis on two when vertical, just formed a kind of threeway coupling that connects straight pipeline and vertical pipe.In like manner, when the interface of joint sleeve 1 was 4, per two were positioned on the same axis, and two interfaces of two interfaces and other wherein are when mutually vertical.Formed a kind of four-way coupling that connects straight pipeline and vertical pipe.
Because the internal diameter of the utility model joint sleeve 1 interface end is greater than the internal diameter of joint sleeve 1 intermediate portion, circumferential seal groove is positioned on the internal diameter of joint sleeve 1 intermediate portion, locking slot is positioned on the internal diameter of joint sleeve 1 interface end, both guarantee the sealing of this pipeline connecting device, formed the inner retaining side for the treatment of block in the connecting tube again.When in locking slot, establishing notched jump ring, in the space of jump ring inboard, establish the packing ring of forming by two semicircles, allow then to treat that block in the connecting tube is laid on the whole circumference, make the block on the coupled pipe stressed evenly, prevented that the point type block is because of the concentrated caducous deficiency of force bearing point, therefore, connection is solid and reliable.After this pipeline connecting device connected pipe, the pressure that is born was particularly suited for the connection of plastic tube and nonferrous metal tube more than or equal to the pressure that coupled pipe bore.For example, connect the pipeline connecting device of bore 8 " * 1/2 " pipe, bear 〉=20kg/cm
2During pressure, still connect, seal reliable.

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
Embodiment 1, with reference to figure 1, Fig. 2, found out by Fig. 1, Fig. 2, and this is one two pipeline connecting devices that are positioned at interface on the same axis to be arranged.Belong to a kind of new-type Pipe jointing part.Two seal grooves 4,5 on the joint sleeve 1 are positioned on the internal diameter of intermediate portion, are positioned in the inner space of jump ring 2, two jump rings of each embedding of locking slot one band breach 6 of interface end by a packing ring 3.This packing ring 3 is made up of two semicircles.Connection process is, pinches the two ends of jump ring 2 breach 6 with instrument, makes its radius-zoom-out break away from locking slot, and packing ring 3 is shifted out.Then seal ring 8,9 is snapped into respectively in the seal groove 5,4, the pipe 7,10 of end band circumference block is extend in the joint sleeve from joint sleeve two interfaces, then two packing rings 3 are snapped into respectively on pipe 7 and the pipe 10, to snap into respectively in the locking slot of joint sleeve with two jump rings 2 of breach 6 at last, thereby finished the process of utilizing this pipeline connecting device that two pipes are connected as one.
In like manner, can also provide embodiment, because the pairing seal groove of interface end, locking slot, jump ring, gasket construction are identical with embodiment 1, so seldom state here with the pipeline connecting device of 4 interfaces.But belong to protection domain of the present utility model.
