Description

PVC loose joint
Technical Field
The utility model relates to a pipe joint field especially relates to a PVC loose joint.
Background
The pipeline uses the pipe, pipe coupling piece and valve, etc. to connect and is used for conveying the gas, liquid, or bring the fluid device of the solid particle, the use of the pipeline is very extensive, mainly used in water supply, water drainage, heat supply, supply gas, long distance transport petroleum and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations, the existing pipe is formed by unit body union coupling, the traditional pipeline is generally connected through the spiro union or welded mode, the spiro union mode is apt to appear leaking water or connect the problem not firm, the leakproofness is very high to the requirement of welding technique, generally the people is difficult to competed, the working efficiency is low.
For the above reasons, a PVC union has been developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art, and provides a PVC loose joint which can effectively prevent the problem of water leakage and greatly improve the working efficiency; the utility model discloses simple structure, the cost is low, light in weight, the transportation transport of being convenient for, the equipment work load is little, site operation is convenient, long service life.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a PVC loose joint is composed of: the straight pipe, the end cover, the reinforcing rib, the sealing ring, the socket joint pipe and the skirt edge; the outer pipe comprises a straight pipe, the outer periphery of the straight pipe is provided with external threads, the upper end and the lower end of the inner wall of the straight pipe are provided with inclined planes, the inclined planes are provided with sealing rings, the upper end and the lower end of the straight pipe are provided with end covers, the end covers are circular, the inner wall of each end cover is provided with an internal thread, the internal thread of each end cover corresponds to the external thread of the straight pipe in a screwed mode, the periphery of the straight pipe below the external threads is provided with a skirt edge, reinforcing ribs are evenly distributed on the periphery of the outer pipe between the skirt edges, the middle part of the inner wall of the straight pipe is provided with an internal.
The utility model has the advantages that: when the sealing ring is used, the position of the socket joint pipe is adjusted according to the length of the pipe, two pipes to be connected are respectively inserted into two ends of the straight pipe, and the end covers are screwed down, so that the working efficiency is greatly improved, the problem of water leakage can be effectively prevented by the sealing ring, and the working efficiency is greatly improved; the utility model discloses simple structure, the cost is low, light in weight, the transportation transport of being convenient for, the equipment work load is little, site operation is convenient, long service life is fit for generally popularizing and applying.
Drawings
The present invention will be further explained with reference to the accompanying drawings:
FIG. 1 is a schematic view of the assembly structure;
in fig. 1: the straight pipe comprises a straight pipe 1, an end cover 2, a reinforcing rib 3, a sealing ring 4, a socket joint pipe 5 and a skirt edge 6.
Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings:
both ends set up the external screw thread about 1 periphery of straight tube, the upper and lower both ends of 1 inner wall of straight tube set up the inclined plane, inclined plane department sets up sealing washer 4, the upper and lower both ends of straight tube 1 set up end cover 2, end cover 2 is ring shape, the inner wall of end cover 2 sets up the internal thread, the internal thread of end cover 2 corresponds the spiro union with the external screw thread of straight tube 1, the 1 periphery of straight tube of external screw thread below sets up shirt rim 6, 1 periphery evenly distributed strengthening rib 3 of outer tube between a pair of shirt rim 6, 1 inner wall middle part of straight tube sets up the internal thread, set up socket joint pipe 5 in the straight tube 1, the upper end periphery of socket joint pipe 5 sets up the external screw thread, the external screw thread of.
