CN2275668Y - Double-soft sleeve three (four)-way inserted structure for quick-coupling of pipe - Google Patents

Abstract

The utility model relates to a double-soft sleeve three (four)-way inserted structure for the quick-coupling of pipelines, which is characterized in that two coaxial pipe openings of the three (four)-way are both insertion opening structures; each insertion opening is directly connected with the original pipeline by a flexible sleeve pipe. The utility model is characterized in that longer construction operation pits are not necessary in the quick-coupling of the pipes; the utility model has the advantages of compact structure, small size, light weight, low labor intensity for workers, high efficiency, easy operations in sealing and installation, quick construction speed, low cost, short time in water supply and stream stop, ensures easily interface quality, and can be applied to the branch pipes installation of water filling pipelines, coal gas pipelines, chemical industry pipelines, etc.

Description

Pipeline adds mouthful double-flexibility sleeve pipe three (four) perfectly straight inserting structures fast

The utility model relates to the joint technical field that allows movable multi-path pipe, specifically is that existing pipeline is added mouthful double-flexibility sleeve pipe three (four) perfectly straight inserting structures fast.

When on the pipeline of having adorned (more than the φ 75mm), adding mouth (arm) operation, two kinds of methods commonly used: the one, pipe is newly installed in dress saddle bit freezing hole on former pipe, welds, but is not suitable for wide-bore; The 2nd, after former pipe blocked, an end linked to each other cement or lead-tight by the socket of a sleeve pipe and a threeway; The other end joins with a flexible sleeve and a straight tube, and straight tube links to each other with the bellmouth of threeway again, therebetween with cement or lead-tight.This method, the mounting structure complexity needs part many, needs long construction to cheat, and is long in time limit, is difficult for sealing, needs downtime long, inconvenience is installed, the cost height.

The purpose of this utility model provides a kind of pipeline and adds mouthful double-flexibility sleeve pipe three (four) perfectly straight inserting structures fast, and this kind connecting structure compactness needs operating pit shorter, labor strength is low, efficient height, easy construction, rapid, easily install, seal, material-saving, cost is lower.

The utility model is achieved in that a kind of pipeline adds mouthful double-flexibility sleeve pipe three (four-way) straight cutting structure fast, it is characterized in that three (four) two logical coaxial mouths of pipe are outlet structure, and each socket all directly is connected with former pipeline by flexible sleeve.

For guaranteeing the quick mounting sealing of straight cutting mouth and flexible sleeve, can on socket, be coated with, or the outer surface that three (four) logical coaxial mouth of pipe sockets are cooperated with flexible sleeve is machining surface with sealer, also can directly use the section bar steel pipe to weld three (four) siphunculus of making.

Because what pipeline adopted when adding fast mouthful is three (four) logical two quick flexible connecting structure of the straight cutting mouth of pipe, so its compact structure, reasonable, in light weight, cost is low, need operating pit shorter during construction, easy to operate, rapid, operation is simple, be easy to sealing, easily guarantees quality of connection, and is durable, duration is short, labor strength is low, efficient is high, and the time of need cutting off the water, stop the supple of gas or steam is short, material-saving, cost is low, remarkable economic and social benefits.Be fit to go up the occasion that fast-assembling three (four) leads on the various existing pipelines such as water, coal gas, chemical industry.

Be described further below in conjunction with embodiment, but not as to qualification of the present utility model.

Fig. 1 is the utility model one embodiment's a structural representation.

Fig. 2 is the prior art constructions schematic representation.

Among Fig. 1, binder lid 1, " O " type plug 2, sleeve pipe 3, gland material 4 constitute flexible sleeve, bolt 5 is tightened, make with the mach left socket of the process of three-way pipe 6 and cooperate with its flexible sealing, the mach right socket of the process of three (four) siphunculus (6) cooperates with another flexible sleeve flexible sealing, 2 interfaces after 7, the 8 last water straight tubes that are respectively original cut off.For diameter is the pipeline of 100mm, disconnected pipe operation length only≤0.5 meter, construction rapidly, good seal, remarkable in economical benefits.

Among Fig. 2, flexible sleeve 9,10 is connected with spigot and socket tee pipe 11 by a prefabricated straight tube 10, and cement or lead joint mouth (YB428-64) three-way pipe 11 right sockets are connected with former pipe end 8 by sleeve pipe 12, cement or lead joint mouth, its poor sealing performance, the operating time is long, and for example diameter is the pipeline of 100mm, need long 〉=1.1 meters of operating pit, construction is slow, need water stopping time long, and labor strength is big, feed consumption, the cost height.

Claims (2)

1, a kind of pipeline adds mouthful double-flexibility sleeve pipe three (four-way) straight cutting structure fast, it is characterized in that three (four) two logical coaxial mouths of pipe are outlet structure, and each socket all directly is connected with former pipeline by flexible sleeve.

2, pipeline according to claim 1 adds mouthful double-flexibility sleeve pipe three (four) perfectly straight inserting structures fast, and it is characterized in that three (four), to collude the outer surface that central siphon mouth socket cooperates with flexible sleeve be machining surface.
