Abstract

The utility model relates to a quick joint for pipelines. The utility model belongs to a pipe joint. The quick joint for pipelines is composed of a connecting body, a pressure ring, a tapered slot press jaw, and a plasticity joint washer. The connecting body is a pipe head with a thread outside, and is sheathed on a pipe needed to be connected. One end of the pressure ring is provided with an internal thread matched with the thread outside the connecting body, and the other end of the pressure ring is provided with an inward flange. One big end of the pressure jaw is opposite to the connecting body. The pressure jaw is installed in the pressure ring. The plasticity joint washer is positioned between the connecting body and the pressure jaw to lead the connecting body and a pressure head to be tightly screwed. The plasticity joint washer is pressed to be deformed by the pressure jaw to connect the pipe and to seal working medium in the pipe. The quick joint for pipelines has the advantages of simple structure, convenient operation, and reliable performance.

Description

A kind of pipeline rapid pipe joint
The utility model belongs to a kind of pipe joint.
In existing piping erection engineering, connecting tube generally adopts on-the-spot mantle fiber to connect, and promptly required pipe on-the-spot mantle fiber earlier, installs then, and mantle fiber can't not installed, so the workman must have the mantle fiber instrument at any time when installation, and is very inconvenient.
The purpose of this utility model is for overcoming the problems referred to above, providing a kind of mantle fiber that need not can realize that pipe is connected with the installation of other parts such as valve with pipe or pipe.
Above-mentioned purpose adopts following measure to realize, it is made up of crack paw and plasticity seal washer of connecting body, pressure ring, taper, and this connecting body is a tube head, and its internal diameter is slightly larger than the external diameter of institute's connecting tube, and be sleeved on the pipe that will connect, tube head is provided with outside thread; One end of this pressure ring is provided with the internal thread that outside thread with connecting body matches, and is screwed in screw thread mutually with connecting body, and the other end of pressure ring is established inward flange, and this flange internal diameter is slightly larger than the connecting body internal diameter; The crack internal diameter of paw of this taper is identical with the connecting body internal diameter, axially has 6-12 bar slit on its small end head, and is provided with internal thread, and with its big termination connecting body is installed in the pressure ring; This plasticity seal washer can adopt plastic washer, and it places between connecting body and the paw.When tightly revolving connecting body and pressure ring, the pressure ring flange promotes paw packing ring extrusion-deformation, thereby the pipe of installation is firmly connected, and the sealing intraductal working medium.
The utility model has the advantages that: can make the piping erection engineering save on-the-spot cover wire process with it, easily pipe directly is connected with other parts (as various elbows, threeway, water tap, radiator and water meter etc.) with pipe or pipe, it is simple in structure, and is with low cost, and installation rate is fast.
Describe the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is this quick coupling structure schematic representation.
Fig. 2 is the taper paw structural representation that cracks.
Wherein, 1 is connecting body, establishes outside thread 5 on the connecting body tube head, and its internal diameter is slightly larger than the pipe 2 that will connect and 3 external diameter, and is sleeved on pipe 2 and 3; One end of pressure ring 4 is established the internal thread 6 that is complementary with connecting body outside thread 5, and the other end is established inward flange 7; The taper paw 8 that cracks is installed in the pressure ring 4 connecting body 1 with its big termination, axially has eight slits 11 on its small end head, and is provided with internal thread 9; Plastic seal packing ring 10 places between paw 8 and the connecting body 1, tightly revolve connecting body 1 and pressure ring 4, the flange 7 of pressure ring promotes 10 distortion of paw 8 extruding plastic seal washers and seals pipe 2 and 3 interior working medium (as water, vapour etc.), the strength of this outer press ring is pressed on the outer wall of pipe 2 paw that cracks, and the paw internal diameter adds internal thread 9 can make the pipe that is connected further reinforce unlikely disengagement.
