Description
Technical field
The present invention relates to a kind of agricultural water conservancy sealing for tubing joints devices, and in particular to a kind of hydraulic engineering pipeline pvc pipe
Road junction sealing structure.
Background technique
Building for pipeline is a more important ring in the construction work of agricultural water conservancy project, due to the length of water conservancy water pipe
It is all certain for spending, and the inadequate pipeline of length just needs the water pipe by two or two or more to connect, but this is just needed
There are two ways to water pipe seal nipple plays the role of being fastenedly connected as the important accessory of connecting pipe, existing, it is a kind of
It is to bond after water pipe and connector heating and connect to the two, the disadvantage is that needing dedicated tool, and cannot dismantle, it is another
It is exactly to be connected with each other using pipe sleeve, but the pipe sleeve of the prior art is usually only to the clamping of pipe outer wall, during irrigation
Since water pipe itself is there are the impact of hydraulic pressure, sleeve pipe structure can simply have the poor easy leak of leakproofness, and water pipe is in irrigation
The problem of easy sliding falls off, and complicated pipe sleeve will increase manufacturing cost, be unable to installing and dismounting or inconvenience；Simultaneously as
PVC water pipe is usually the general part produced in batches, in assembly, very to the concentricity, tube wall thickness and forming requirements of PVC water pipe
Height, after the damage of PVC water pipe, sealing structure can be generally also dropped, and be resulted in waste of resources.
Summary of the invention
In view of the deficiencies of the prior art, the technical problem to be solved in the present invention is to provide a kind of agricultural water conservancy PVC pipelines
Junction sealing structure, the sealing structure have structure simple, easy for assemble or unload, and antileaking falls off, reusable etc.
Feature is suitble to promote and apply in irrigation and water conservancy irrigating facility.
To realize that listing can make the effect of PVC water pipe connection sealing, technical solution provided by the invention is as follows:
A kind of agricultural water conservancy PVC pipeline junction sealing structure, including main pipe, left sealing element and right sealing element, it is described
Main pipe is divided into horizontal segment, left connection part and right connection part, wherein left connection part and right connection part respectively with left sealing element and the right side

The structure of left and right linkage section is continuous zigzag configuration, and the outer wall of the left and right linkage section is provided with external screw thread one, it is described it is left,
The end tip of right connection part is V-arrangement inner lip, and the outer tube is continuous L-shaped structure, and inner wall is provided with two sections of internal screw threads,
Respectively internal screw thread one and internal screw thread two, internal screw thread one and internal screw thread two are located at the horizontal segment of outer tube, the external screw thread
One is screwed on the internal screw thread one of the outer tube, and the inner lip is docked with the V-arrangement external lip of the inner sleeve pipe outer wall protrusion, institute
It states main pipe and is provided with O-shaped rubber seal, the inner sleeve and institute between the inner sleeve at the left and right linkage section
It states and is provided with external screw thread two on the outer wall of main pipe's opposite side, the external screw thread two is screwed on the internal screw thread two, described interior
The inner wall of casing and main pipe's opposite side is in the gradually smaller open-like shape of thickness, is set in the inner sleeve inside pipe wall horizontal segment
It is equipped with waterproof layer, section is equipped between the open-like shape inner wall and PVC pipeline into wedge-shaped rubber seal, when fit sealing, PVC
Pipeline is sequentially inserted into outer tube, inner sleeve and main pipe, two sections of internal screw threads of the outer tube and the external screw thread one of main pipe and
The external screw thread two of inner sleeve cooperates precession and then the V-arrangement external lip of the inner sleeve is pushed to dock and press with the inner lip of main pipe
Real O-shaped elastic seal ring and wedge-shaped rubber seal seal PVC pipeline.
Further, the waterproof layer uses material for the hollow cylindrical of rubber, and the face contacted with PVC water pipe is at recessed
Convex not flat-shaped, after installation fastening, the waterproof layer and PVC water pipe are fitted closely together, further prevent water flow to reveal, simultaneously
Also the resistance that can increase horizontal direction between sealing structure and PVC water pipe, avoids loosening.
Further, the outer shape of the main pipe is hexagon, be conducive to screw left and right end seal with respectively with
The sealing of main pipe fastens.
Further, the housing tube outer surface has trench groove or protrusion, increases contact friction force when being conducive to be screwed on,
Installation easy to disassemble.
The present invention is by adopting the above-described technical solution, have the advantages that
1, this sealing structure structure is simple, is constituted using main pipe, inner tube set and outer tube sleeve three parts, each section can be independent
Manufacture is screwed on assembling by internal and external threads at two, is easily installed and dismantles, can also weigh through replacing pipeline after PVC pipeline damage
It is multiple to use, agricultural cost is reduced, while the cooperation of two sections of internal and external threads avoids causing PVC pipeline de- because of the influence of hydraulic pressure etc.
It falls；
2, this sealing structure passes through pressurization three times --- O-shaped rubber seal, waterproof layer, the voussoir rubber of elastic packing
Glue sealing ring, it is ensured that entire sealing structure does not leak in long-time use because of ageing of rubber.
