Abstract
The utility model relates to a PE conveying pipe for natural gas installation, in particular to an anti-shearing steel-plastic adapter, which comprises a section of PE conveying pipe sleeved on a bypass steel pipe, and a locking sleeve arranged at the joint of the PE conveying pipe and the bypass steel pipe, wherein the locking sleeve is sleeved at the outer wall of the PE conveying pipe; wherein: the left part of the locking sleeve is provided with an extension pipe section, and a shearing force resistant filling pipe is filled between the extension pipe section and the outer wall of the PE conveying pipe. The utility model provides high life, improved the safety in utilization and reduced the later maintenance cost.
Description
Technical Field
The utility model relates to a PE delivery pipe connects is used in the natural gas installation, especially an improve life, improve safety in utilization and reduce later maintenance cost's crossover sub is moulded to anti-shearing steel.
Background
In the natural gas conveying process in the prior art, the PE conveying pipe buried underground needs to be communicated with a PE conveying pipe joint through a bypass pipe to realize the communication between the load of a user and a gas transmission main pipe because sunlight cannot be seen, the bypass pipe in the prior art is a steel pipe and is generally called a bypass steel pipe, the bypass steel pipe is inserted into one end of the PE conveying pipe joint, and then the joint is locked through an external locking sleeve to realize the installation and connection of the bypass steel pipe and the PE conveying pipe joint. The PE conveying pipe joint with the structure has poor corrosion resistance in the using process, stress concentration exists at the joint of the outer lock sleeve and the end part of the PE conveying pipe joint due to the settlement of landfill soil, the risk of shearing exists along with the use time, once the joint of the outer lock sleeve and the end part of the PE conveying pipe joint is sheared, natural gas leakage is caused, and safety accidents are easily caused. In order to ensure the use safety of the natural gas, safety personnel dispatched by a gas company are required to check potential safety hazards at intervals, the later maintenance cost is high, and the service life is short.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an improve life, improve the safety in utilization and reduce later maintenance cost's crossover sub is moulded to anti-shearing steel.
The technical scheme adopted for achieving the purpose is that the anti-shearing steel-plastic adapter comprises a PE conveying pipe and a locking sleeve, wherein the PE conveying pipe is sleeved on a bypass steel pipe; wherein: the left part of the locking sleeve is provided with an extension pipe section, and a shearing force resistant filling pipe is filled between the extension pipe section and the outer wall of the PE conveying pipe.
The structure of the utility model has the advantages that: the service life is prolonged, the use safety is improved, and the later maintenance cost is reduced.
Drawings
The invention can be further illustrated by means of non-limiting examples given in the figures.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
referring to the attached drawing 1, the shear-resistant steel-plastic adapter in the drawing comprises a section of PE conveying pipe 2 sleeved on a bypass steel pipe 1, and a locking sleeve 3 arranged at the joint of the PE conveying pipe 2 and the bypass steel pipe 1, wherein the locking sleeve 3 is sleeved on the outer wall of the PE conveying pipe 2; wherein: the left part of the locking sleeve 3 is provided with an extension pipe section, and a shearing force resistant filling pipe 4 is filled between the extension pipe section and the outer wall of the PE conveying pipe 2. In this embodiment, the weakest department of PE conveyer pipe has effectively been guaranteed in the setting of anti-shear force filling tube 4, has effectively guaranteed PE conveyer pipe 2 promptly and has managed 1 junction department with the bypass steel, has reached the purpose of well-being-sheared, has improved life, has improved the safety in utilization and has reduced the later maintenance cost.
In order to ensure the stability of connection, and the tightness, further improve safety and service life, in the above embodiment, preferably: and an anti-disengaging structure 5 meshed with each other is arranged at the joint part of the PE conveying pipe 2 and the bypass steel pipe 1 and/or the joint part of the PE conveying pipe 2 and the locking sleeve 3.
In order to ensure the corrosion resistance and further prolong the service life, in the above embodiment, preferably: and an anti-corrosion sleeve 6 is arranged at the outer end of the joint of the PE conveying pipe 2 and the bypass steel pipe 1.
For ease of manufacture, in the above embodiments, preferably: the anti-corrosion sleeve 6 is made of PE material. The shear-resistant filling pipe 4 is filled in a tubular shape with a PE material.
It is obvious that all the embodiments described above are some, not all embodiments of the present invention. Based on the embodiment of the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the scope of the protection of the present invention.
To sum up, because of above-mentioned structure, the utility model provides high life, improved the safety in utilization and reduced the later maintenance cost.
