Description

Technical Field

[0001] This utility model relates to the field of pipelines, and in particular to a corrosion-resistant ventilation duct lining structure. Background Technology

[0002] Pipeline lining is a system where the outer layer is made of steel or a rigid structure, and the inner layer is made of wear-resistant, corrosion-resistant, and high-temperature-resistant rubber. The physical and chemical properties of the rubber itself reduce the impact of the pipeline transported medium on the external structure, such as impact and corrosion.

[0003] While existing pipe linings are installed in two halves, which can prevent air intake and reduce risks, their sealing effect is poor. Gaps exist when the two sections of the lining are connected, the connection is not tight enough, the upper lining cannot be effectively fixed, resulting in poor stability. Moreover, their pressure and impact resistance is poor. When the pipe is subjected to external impact, the inner lining cannot effectively resist the impact force and is prone to cracking and deformation after being subjected to external impact, making it less practical. In order to solve the above problems, we propose a corrosion-resistant ventilation duct lining structure. Utility Model Content

[0004] The purpose of this invention is to provide a corrosion-resistant ventilation duct lining structure that solves the problems of poor fixing effect and poor pressure and impact resistance of existing duct linings.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a corrosion-resistant ventilation duct lining structure, including a first lining, a second lining at the bottom of the first lining, a connecting member symmetrically arranged between the first and second linings, a limiting member installed at the top and bottom of the connecting member, a limiting groove opened on the opposite side of the first and second linings, a fixing bolt penetrating through the interior of the first and second linings, a threaded hole opened inside the limiting member, a pressure-resistant layer installed on the surface of the first and second linings, and through holes opened on the front of the first lining, the second lining, and the connecting member, with a reinforcing rod installed inside the through hole.

[0006] The above technical solution can improve the fixing effect of the lining, enhance the sealing and stability of the lining, and has high practicality. At the same time, it can achieve good pressure resistance and impact resistance, significantly increase the impact resistance of the pipeline, improve its service life, and ensure high safety.

[0007] The present invention is further configured such that the first liner, the second liner, and the connector are all made of PVC material.

[0008] Using the above technical solution, the first liner, the second liner, and the connector have good acid resistance, alkali resistance, and durability.

[0009] The present invention is further configured such that the interior of the first liner, the second liner, and the connector are all fitted with an anti-corrosion layer.

[0010] By adopting the above technical solution and setting the anti-corrosion layer, the anti-corrosion effect inside the first liner, the second liner and the connector can be improved.

[0011] The present invention is further configured such that the fixing bolt is made of stainless steel.

[0012] Using the above technical solution, the fixing bolts have the characteristics of high strength, low density and excellent corrosion resistance.

[0013] The present invention is further configured such that a moisture-proof layer is installed on the surface of the pressure-resistant layer.

[0014] By adopting the above technical solution and setting up a moisture-proof layer, the moisture-proof effect against the outside can be improved, and it can also play a certain role in heat preservation.

[0015] The present invention is further configured such that the compressive layer is made of glass fiber material.

[0016] Using the above technical solution, the compression layer, through winding, curing, and composite molding, has the characteristics of high strength, corrosion resistance, aging resistance, impact resistance, and insulation and flame retardancy.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model involves placing the first liner and the second liner into the pipe one after the other. After the first liner and the second liner are placed in, the connector is picked up and inserted from the front. When the connector is inserted, the limiting member needs to enter the limiting groove. After the connector is fully inserted and aligned with the first liner and the second liner, the fixing bolt is inserted from the through groove and screwed into the threaded hole. This can improve the fixing effect of the liner, improve the sealing and stability of the liner, and has high practicality.

[0019] 2. This utility model inserts a reinforcing rod into the through hole from the front. When the pipe is impacted by external force, the impact force is first transmitted inward to the pressure-resistant layer. The pressure-resistant layer initially offsets and absorbs the force. When the force is too large and causes the pressure-resistant layer to deform inward, it will press on the reinforcing rod. The reinforcing rod will absorb, disperse and protect the force a second time. This achieves good pressure resistance and impact resistance, significantly increases the impact resistance of the pipe, improves its service life, and enhances safety. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] refer to Figure 1 , Figure 2 and Figure 3 A corrosion-resistant ventilation duct lining structure includes a first lining 1, a second lining 2 at the bottom of the first lining 1, and a connector 3 symmetrically arranged between the first lining 1 and the second lining 2. Limiting elements 4 are installed at the top and bottom of the connector 3. Limiting grooves 5 are formed on opposite sides of the first lining 1 and the second lining 2. Fixing bolts 6 are inserted through the interior of both the first lining 1 and the second lining 2. Threaded holes 7 are formed inside the limiting elements 4. The first lining 1 and the second lining 2 are inserted into the duct sequentially. After insertion, the connector 3 is lifted and inserted from the front. When inserting the connector 3, the limiting elements 4 must enter the limiting grooves 5. Once the connector 3 is fully inserted and aligned with the first lining 1 and the second lining 2, the fixing bolts 6 are inserted from the grooves and screwed into the threaded holes 7. This structure improves the fixing effect of the lining, enhances its sealing and stability, and is highly practical.

[0028] refer to Figure 1 , Figure 2 and Figure 3 The first liner 1, the second liner 2, and the connector 3 are all made of PVC material. The first liner 1, the second liner 2, and the connector 3 have good acid resistance, alkali resistance, and durability.

[0029] refer to Figure 1 , Figure 2 and Figure 3 The first liner 1, the second liner 2, and the connector 3 are all equipped with an anti-corrosion layer 11. The anti-corrosion effect of the first liner 1, the second liner 2, and the connector 3 can be improved by setting the anti-corrosion layer 11.

[0030] refer to Figure 1 and Figure 3 The fixing bolt 6 is made of stainless steel and features high strength, low density and excellent corrosion resistance.

[0031] Brief description of the usage process: First liner 1 and second liner 2 are placed into the pipe one after the other. After the first liner 1 and second liner 2 are placed, the connector 3 is picked up and inserted from the front. When the connector 3 is inserted, the limiting member 4 needs to enter the limiting groove 5. After the connector 3 is inserted to the bottom and aligned with the first liner 1 and second liner 2, the fixing bolt 6 is inserted from the through groove and screwed into the threaded hole 7.

[0032] Example 2:

[0033] refer to Figure 1 , Figure 2 and Figure 4 A corrosion-resistant ventilation duct lining structure is disclosed, wherein a pressure-resistant layer 8 is installed on the surface of both the first liner 1 and the second liner 2. Through holes 9 are provided on the front of the first liner 1, the second liner 2, and the connector 3. A reinforcing rod 10 is installed inside the through hole 9. By inserting the reinforcing rod 10 into the through hole 9 from the front, when the duct is subjected to external impact, the impact force is first transmitted inward to the pressure-resistant layer 8, which initially offsets and absorbs the force. When the force is too large and causes the pressure-resistant layer 8 to deform inward, it will compress the reinforcing rod 10. The reinforcing rod 10 will then absorb, disperse, and protect the force a second time. This structure achieves good pressure and impact resistance, significantly increases the duct's impact resistance, improves its service life, and enhances safety.

[0034] refer to Figure 1 and Figure 4 A moisture-proof layer 12 is installed on the surface of the pressure-resistant layer 8. The moisture-proof layer 12 can improve the moisture-proof effect against the outside and also play a certain role in heat preservation.

The compression layer 8 is formed by winding, curing and composite molding, and has the characteristics of high strength, corrosion resistance, aging resistance, impact resistance and insulation and flame retardancy.

[0036] Brief description of the usage process: By inserting the reinforcing rod 10 into the through hole 9 from the front, when the pipe is impacted by external force, the impact force will first be transmitted inward to the pressure-resistant layer 8. The pressure-resistant layer 8 will initially offset and absorb the force. When the force is too large and causes the pressure-resistant layer 8 to deform inward, it will press the reinforcing rod 10. The reinforcing rod 10 will absorb, disperse and protect the force a second time.
