Description

Quick joint for pipeline

Technical Field

The utility model relates to a quick-operation joint of pipeline that pipeline was used.

Background

Urban water supply and drainage pipe network systems usually adopt cement, cast iron, galvanized steel pipes or plastic pipes, and because the length of the pipes is long, the short pipes are usually required to be connected.

As shown in fig. 1, a conventional pipe quick coupling generally comprises a cast iron housing and a rubber ring, wherein the rubber ring is generally disposed at two ends of the pipe quick coupling and has no anti-separation structure, and the actual sealing position is not at the actual connection position of the pipe. Therefore, the pipeline can fall off in the actual use process, and the sealing ring can be flushed away by high-pressure water flow in the actual use process. And liquid in the pipeline can enter the half joint, especially corrosive liquid can corrode the internal structure of the half joint after entering the half joint, and the mode that is easily thought about for the situation is to adopt the half joint made of corrosion-resistant materials, but the cost is inevitably increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a pipeline quick-operation joint can two treat the pipeline of connecing of good sealing connection.

The utility model discloses a following technical scheme, a pipeline quick-operation joint, establish the pipe sleeve joint on two pipe joints of treating, pipe sleeve joint inner chamber middle part is provided with sealed gum cover, and pipe sleeve joint extrusion sealed gum cover makes its radial deformation.

When the pipeline quick connector in the scheme is used, the sealing rubber sleeve is aligned to the position to be connected, and then the sealing rubber sleeve is extruded through the pipe sleeve joint to be blocked at the sealing position, so that the sealing rubber sleeve directly acting on the connecting position has a better sealing effect, and liquid in a pipeline cannot enter the Hough section to corrode the Hough section.

The specific implementation mode is as follows:

a quick pipeline joint comprises a pipe sleeve joint sleeved on two pipelines 1 to be connected, wherein a sealing rubber sleeve 20 is arranged in the middle of an inner cavity of the pipe sleeve joint, and the pipe sleeve joint extrudes the sealing rubber sleeve 20 to enable the sealing rubber sleeve 20 to deform in the radial direction.

When the pipeline quick connector is in actual use, the joint of two pipelines 1 to be connected is generally positioned in the middle of the pipeline quick connector, so that the sealing rubber sleeve 20 is aligned to the position to be connected and then the sealing rubber sleeve 20 is extruded through the pipe sleeve joint to be blocked at the sealing position in the actual use of the scheme, the sealing rubber sleeve 20 directly acting on the joint has better sealing effect, and liquid in the pipeline cannot enter the half joint to corrode the half joint.

The pipe sleeve joint is formed by encircling two half-half bodies 10, and the two half-half bodies 10 are close to each other to extrude the sealing rubber sleeve 20 to deform in the radial direction. The structure is simple and the installation and the manufacture are more convenient.

The half-half body 10 is provided with a limit groove 11 in the middle of the inner cavity for accommodating a semicircular ring of the sealing rubber sleeve 20. The sealing rubber sleeve 20 is prevented from axially moving in the half-half body 10, and the limit groove 11 axially deforms and limits the sealing rubber sleeve 20, so that the radial extrusion force of the sealing rubber sleeve 20 is improved.

The groove bottom of one end of the limiting groove 11 protrudes to form a positioning boss 111, the other end of the limiting groove is recessed to form a positioning concave table 112, and the positioning boss 111 and the positioning concave table 112 form an embedded fit. This allows the two half-halves 10 to have the same structure and to be manufactured using the same mold.

The two ends of the limiting groove 11 of one half-half body 10 are protruded to form a positioning boss 111, the two ends of the limiting groove 11 of the other half-half body 10 are recessed to form a positioning concave table 112, and the positioning boss 111 and the positioning concave table 112 form an embedded fit. The male half body 10 and the female half body 10 can be distinguished conveniently, and identification is facilitated.

The inner walls of the half-half bodies 10 on two sides of the sealing rubber sleeve 20 are circumferentially and continuously or discontinuously provided with anti-disengaging teeth 12, the anti-disengaging teeth 12 on the two half-bodies 10 form an anti-disengaging gear ring, and the inner diameter of the anti-disengaging gear ring is reduced when the two half-bodies 10 are close to each other. During installation, the anti-falling teeth 12 on the two half-half bodies 10 are pressed on the pipe wall to prevent the pipeline to be connected from axially falling off.

The two sides of the inner ring of the sealing rubber sleeve 20 are in a bell mouth shape with a small middle and two large ends. This is beneficial to the inner ring of the sealant sleeve 20 being squeezed into the pipe joint to seal more effectively.

An annular groove 21 is formed in the inner ring of the sealing rubber sleeve 20, and the notch of the annular groove 21 is located between the two bell mouths. In the in-service use process like this, the notch of ring channel 21 can imbed the pipeline junction, and rivers just can get into and fill ring channel 21 from the notch and order about sealed gum cover 20 and expand, promote sealed effect, because spacing groove 11 has carried out the axial spacingly to sealed gum cover 20, sealed gum cover 20 only can be under the water pressure effect outer lane to the half extrusion of huff section, the inner circle is to the pipe wall extrusion of taking over pipeline 1.

The two half-half bodies 10 are connected through square-neck bolts 30, and square holes are formed in the two half-half bodies 10 corresponding to the square-neck bolts 30. The bolt is prevented from loosening and falling off.
