Abstract
The utility model relates to a quick-to-mount pipe joint which comprises a flange disc, bolts and a sleeve pipe. The utility model is characterized in that the middle section of the sleeve pipe is a right cylinder hole; two ends of the sleeve pipe have inverse cone cutting hole structure; the bottom end of each of inverse cone cutting holes is provided with a sealing ring; a split locking ring is arranged in the inverse cone cutting holes; the bottom end of each of the locking ring is pressed on a gasket which is pressed on the sealing rings. The utility model can well solve the problems existing in the traditional pipe joints that the traditional pipe joints adopt a connection mode that the traditional pipe joints are connected after the flange disc is welded, the operation is complicated, the efficiency is low, the flange disc can not be welded in inflammable and detonable situations, etc. The utility model has the advantages of simple operation, no special devices, convenient use in various situations, no limitation of environmental conditions, favorable sealing effects and no leakage; the flange disc does not need welding; professionals can operate the utility model; the top end of the sleeve pipe adopts the right cylinder hole; a sealing cavity is in an airtight state after installation; the locking ring adopts the split structure, so the installation is convenient, a surface contact is formed to enlarge locking force and the effects of locking are ensured.
Description
One, technical field: the utility model relates to a kind of pipe joint, particularly relate to a kind of quick and easy for installation, safety, good seal performance can be applied to the joint of various pipelines joint.
Two, background technique: in various industries, the pipeline that transportation of substances is used is very general, joint to various pipelines, adopt respectively welded a flange plate with two tube heads more, after installing the seal ring butt joint between the flange plate additional, by bolton two pipes are coupled together, but the Placement of this tube head exists: 1, complicated operation, the electric equipment that needs professional workforce and specialty, very inconvenient as field work; 2, can't operate because of not using electric welding in inflammable and explosive occasions such as chemical plant, oil fields; 3, the work complexity causes efficient lower.
Three, summary of the invention:
1, goal of the invention: the utility model provides a kind of fast holding pipe joint, and purpose is to solve traditional tube head Placement and needs connect behind the welding flange, complicated operation, efficient is low, inflammable and explosive occasion can't welding flange etc. the problem that exists of aspect.
2, technological scheme: the utility model is achieved through the following technical solutions:
A kind of fast holding pipe joint, this pipe joint comprises flange plate, bolt, sleeve pipe, it is characterized in that: the stage casing is the straight cylinder hole in the sleeve pipe, for falling to cut the vertebral foramen structure, falls to cut the vertebral foramen bottom and is provided with seal ring in the sleeve pipe two ends; The opposite opened locking ring is located at down and cuts in the vertebral foramen, and the locking ring bottom is pressed on the packing ring, and packing ring is pressed on the seal ring.
Falling to cut the vertebral foramen structure is made of two sections sections vertebral foramens and straight cylinder hole, top.
3, advantage and effect: by the enforcement of technical solutions of the utility model, can solve traditional tube head Placement well needs connect behind the welding flange, complicated operation, efficient is low, inflammable and explosive occasion can't welding flange etc. the problem that exists of aspect.The utility model advantage is as follows:
1, without welding flange, simple to operate, can operate without special device and professional workforce;
2, all be easy to use in various occasions, be not subjected to the restriction of environmental conditions;
3, good sealing effect does not have and reveals;
4, cannula tip adopts the straight cylinder hole, and the Seal cage after the installation is an air-tight state;
5, locking ring is the opposite opened structure, and is easy for installation, and the contact of formation face strengthens coupling mechanism force, guarantees locking effect.
Four, description of drawings: accompanying drawing 1 is the utility model structural representation.
Five, embodiment:
Among the figure: 1, packing ring; 2, sleeve pipe; 3, seal ring; 4, locking ring; 5, flange plate; 6, bolt.
As shown in Figure 1, the fast holding pipe joint of the utility model, this pipe joint comprises the flange plate 5 that is arranged on institute's connecting tube joint, the bolt 6 of mounting flange 5, be arranged on the sleeve pipe on the pipe joint 2 between the flange plate 5, the stage casing is the straight cylinder hole in the sleeve pipe 2, and section vertebral foramen structure of falling for being made of two sections sections vertebral foramens and straight cylinder hole, top in sleeve pipe 2 two ends is fallen to cut the vertebral foramen bottom and is provided with seal ring 3; Opposite opened locking ring 4 is located at down and cuts in the vertebral foramen, and locking ring 4 bottoms are pressed on the packing ring 1, and packing ring 1 is pressed on the seal ring 3.
Use of the present utility model is as follows: when installing at the scene, on the tube head of two pipelines that will connect, overlap upper flange plate, overlap upper gasket again, put seal ring then, two tube heads are packed in the straight cylinder hole, stage casing of sleeve pipe, at last, between pipeline outward flange dish and packing ring, load onto locking ring, with bolt that two flange plate are fastening, under the effect of two flange plate, locking ring holds on to two working lines, and tube head is combined closely with the stage casing in sleeve pipe, realizes sealing by seal ring.
Claims (2)
1, a kind of fast holding pipe joint, this pipe joint comprise flange plate (5), bolt (6), sleeve pipe (2), it is characterized in that: the interior stage casing of sleeve pipe (2) is the straight cylinder hole, for falling to cut the vertebral foramen structure, falls to cut the vertebral foramen bottom and is provided with seal ring (3) in sleeve pipe (2) two ends; Opposite opened locking ring (4) is located at down and cuts in the vertebral foramen, and locking ring (4) bottom is pressed on the packing ring (1), and packing ring (1) is pressed on the seal ring (3).
2, according to the fast holding pipe joint described in the claim 1, it is characterized in that: fall to cut the vertebral foramen structure and constitute by two sections sections vertebral foramens and straight cylinder hole, top.
