Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Example 1
Please refer to fig. 1.
The embodiment discloses a hidden double-sleeve buckled wear-resistant high-voltage connector, which comprises a connector inner layer 6 and a connector outer layer 7 which are communicated, wherein the connector inner layer 6 is embedded with a connector inner sleeve 5, the outer end of the connector outer layer 7 is sleeved with a connector outer sleeve 8, and the connector outer sleeve 8 is externally clamped with a flange 9.
The traditional joint is usually only provided with an outer sleeve, only depends on the prestress of the outer sleeve and the pipe, and has poor sealing effect, because the pipe is of a plastic structure, is a plastic non-rigid material and is easy to creep, and the outer sleeve cannot form great reaction force and cannot seal higher pressure.
In order to improve the defects, the joint adopts a mode of matching the inner sleeve and the outer sleeve, namely the joint inner sleeve 5 and the joint outer sleeve 8 are simultaneously arranged, wherein when the joint outer sleeve 8 is buckled on the joint outer layer 7 (the joint outer layer 7 and the pipe outer layer 4 are integrally formed), the joint inner sleeve 5 plays a supporting role to form a reaction force, so that the joint outer sleeve is more beneficial to ensuring that the joint outer sleeve always maintains the pre-stress pressure on the pipe after yielding deformation, and the sealing reliability and the pressure resistance of a sealing surface are ensured.
However, the common inner sleeve and the outer sleeve are buckled and pressed at the same time, and although a better sealing effect can be formed, the inner sleeve is generally arranged outside the surface of the wear-resistant layer of the pipe, and the defects are that: 1. the pipe circulation is reduced, and the inner sleeve has a certain thickness, so that a step is formed on the inner wall of the pipe, and the conveying resistance is increased; 3. the inner sleeve is directly placed in the conveying slurry, and mineral substances or metal particles and the like in the slurry can generate strong abrasion and corrosion (the abrasion resistance of the conventional carbon steel material to mortar and ore pulp is very low, and the acid and alkali corrosion resistance is very low) on the inner sleeve under certain pressure and flow rate when the pipeline works.
In order to improve the above-mentioned drawbacks, the inner sleeve 5 of the joint of the present embodiment is hidden in the structure of the pipe (inner layer of the joint), which can tightly combine the joint with the pipe by a double-layer buckling method, and does not affect the flow rate of the pipe and the joint, and the inner sleeve is not contacted with mineral particles, metal particles, etc. in the slurry, so as to avoid continuous abrasion of the inner sleeve by mineral substances, metal particles, etc. in the conveying medium until the inner sleeve is consumed and the final integral structure is lost, resulting in joint sealing failure. The disassembly and communication between the pipes can be achieved by bolting the flanges 9 of adjacent pipe joints.

The present embodiment provides a hidden double-sleeve buckled and pressed wear-resistant high-pressure joint, which is basically the same as that of embodiment 1, and the same features are not repeated, except that the layer section of the joint outer sleeve 8 in the present application is l, and a sealing water plane is arranged on the joint outer sleeve 8.
The sealing water plane is arranged on the joint outer sleeve 8, has better sealing performance, and particularly has better sealing effect when adjacent pipes are connected, so that the circulation of materials is ensured.
The joint inner sleeve 5, the joint outer sleeve 8 and the flange 9 are made of high-pressure resistant materials, and specifically, the joint inner sleeve 5, the joint outer sleeve 8 and the flange 9 in the embodiment are all made of steel materials. It has better high pressure resistance.
Further, the inner joint layer 6 in this embodiment is made of a high-pressure wear-resistant material, and the outer joint layer 7 is made of a high-molecular material, preferably high-density polyethylene in this embodiment.
The reinforcing layer 3 is arranged between the joint inner layer 6 and the joint outer layer 7, and the reinforcing layer 3 is made of steel fibers, so that the whole joint is provided with better pressure resistance. The reinforcing layer 3 divides the interior of the whole joint into two parts, a joint inner layer 6 and a joint outer layer 7, and in this embodiment the reinforcing layer 3 does not completely separate the joint inner layer 6 and the joint outer layer 7, i.e. the two parts communicate, so that the whole joint part has a better integrity.
Example 3
Please refer to fig. 1.
The embodiment provides a composite pipe comprising the high-pressure joint of the embodiment 1 or the embodiment 2, and further comprising a pipe, wherein the pipe comprises a pipe wear-resistant layer 1, a pipe inner layer 2, a reinforcing layer 3 and a pipe outer layer 4 from inside to outside; the inner pipe layer 2, the reinforcing layer 3 and the outer pipe layer 4 of the pipe are respectively connected with the inner joint layer 6, the reinforcing layer 3 and the outer joint layer 7 of the joint.
Namely, the composite pipe in the embodiment is composed of a pipe and a joint, wherein the inner layer 2 of the pipe and the inner layer 6 of the joint are formed, the reinforcing layer 3 positioned in the pipe and the reinforcing layer 3 positioned in the joint are in one-to-one correspondence and are connected, the outer layer 4 of the pipe and the outer layer 7 of the joint are made of the same materials, so that the manufacturing is convenient, and the compression resistance and the wear resistance of the joint can be guaranteed.
Further, the pipe and the joint are integrally formed, so that the pipe inner layer 2 and the joint inner layer 6 are more convenient, the reinforcing layer 3 positioned in the pipe and the reinforcing layer 3 positioned in the joint are combined in a seamless and dislocation-free manner, the sealing performance is enhanced, and the manufacturing is also more convenient.
Furthermore, the outer diameter of the pipe extending to the joint is obviously increased in gradient, so that the whole joint and the pipe structure can be reinforced.
Example 4
Please refer to fig. 1.
The present embodiment provides a composite pipe, which is substantially the same as the composite pipe provided in embodiment 3, and the same points are not repeated, except that the pipe wear-resistant layer 1 in the present embodiment is further disposed at the inner end of the joint inner layer 6.
Namely, the wear-resistant layer 1 of the pipe is not only positioned at the innermost end of the pipe, but also positioned at the innermost end of the joint, namely, the material passing inner diameter of the joint is identical with the material passing inner diameter of the pipe and the material of the innermost layer is identical, so that the flow and the resistance of the material passing are not influenced, and the stable operation of material conveying can be further maintained.
In summary, the application provides a double-sleeve buckled wear-resistant high-pressure joint and a composite pipe, which have the following advantages:
1. The inner sleeve of the connector is hidden and embedded in the inner layer of the connector, and the conveying medium cannot contact the inner sleeve of the metal connector, so that the pressure resistance is improved by using the inner sleeve of the connector as the joint, and the problem of abrasion of the inner lining metal sleeve is solved.
