Description

Technical Field

[0001] The utility model relates to the technical field of insulating pipes, in particular to a Teflon insulating pipe with good sealing performance. Background Technique

[0002] An insulating pipe is short for an adiabatic pipe. Insulating pipes are used for the transportation of liquids, gases and other media, and are used for the adiabatic engineering insulation of pipes in petroleum, chemical industry, municipal engineering, etc. When in use, multiple insulating pipes are connected together to realize the transportation of liquids and gases.

[0003] For example, in the utility model: "A rock wool insulating pipe with good connection sealing performance", the publication number is: "CN209671876U". This patent makes the rock wool insulating pipes be tightly connected and have good sealing performance by setting mutually matching protruding parts at the first connection end and the second connection end of the rock wool insulating pipe, thus ensuring the heat preservation effect of the rock wool pipe. However, in the implementation process of this patent, no reinforcement structure is arranged outside the rock wool pipe body. When the rock wool pipe body is subjected to a large impact force, it is easy to break directly, thus affecting the sealing performance and heat preservation performance of the rock wool pipe. Therefore, the present utility model provides a Teflon insulating pipe with good sealing performance to solve the above problems. Content of the Utility Model

[0004] The purpose of the present utility model is to provide a Teflon insulating pipe with good sealing performance to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A Teflon insulating pipe with good sealing performance, including an insulating outer pipe, a connecting outer sleeve, a Teflon insulating pipe and a rubber connecting pipe. The connecting outer sleeve is installed inside the insulating outer pipe, and the Teflon insulating pipe is installed inside the connecting outer sleeve. One end of the insulating outer pipe is installed with a rubber connecting pipe. A reinforcing outer pipe is installed outside the Teflon insulating pipe, and a stainless steel mesh sleeve is installed outside the reinforcing outer pipe. An installation inner groove is arranged inside the insulating outer pipe.

[0006] Preferably, a sealing rubber insert is installed at the top of the end of the rubber connecting pipe away from the insulating outer pipe.

[0007] Preferably, reinforcing support blocks are evenly installed inside the reinforcing outer pipe.

[0008] Preferably, heat insulating cotton is evenly arranged inside the reinforcing outer pipe.

[0009] Preferably, a circulating water inlet and outlet are arranged at the top of the insulating outer pipe.

[0010] Preferably, a sealing rubber ring is installed inside the installation inner groove.

[0011] Preferably, a sealing slot is provided at the bottom of the rubber connecting tube away from the end of the thermal insulation outer tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The Teflon insulation pipe with good sealing performance is installed with a rubber connecting pipe and a sealing rubber insert, and a sealing slot is arranged on the rubber connecting pipe. When two groups of rubber connecting pipes are connected, the sealing rubber insert on one group of rubber connecting pipes can be inserted into the sealing slot on the other group of rubber connecting pipes. The sealing rubber insert covers the gap at the connection position of the two groups of rubber connecting pipes, which can prevent circulating water from leaking through the gap between the two groups of rubber connecting pipes, thereby effectively improving the sealing performance.

[0014] The Teflon insulation pipe with good sealing performance is installed with a Teflon insulation pipe, a reinforcement support block, a stainless steel mesh sleeve and a reinforced outer pipe. The outer side of the Teflon insulation pipe can be reinforced by the stainless steel mesh sleeve. When the reinforced outer pipe is locally subjected to a large impact pressure, the reinforced outer pipe can evenly disperse the impact pressure to multiple groups of reinforcement support blocks. Not only can it be supported by the reinforcement support blocks, but the impact pressure can also be evenly transmitted to different positions of the Teflon insulation pipe through multiple groups of reinforcement support blocks, so that different positions of the Teflon insulation pipe are subjected to uniform force, thereby preventing the Teflon insulation pipe from breaking due to large local force.

[0015] The Teflon insulation pipe with good sealing performance is provided with insulation cotton inside the reinforced outer pipe. The Teflon insulation pipe has good heat resistance, cold resistance and corrosion resistance. The insulation cotton is used together to effectively improve the insulation effect of the reinforced outer pipe and the Teflon insulation pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention: a Teflon heat-insulating pipe with good sealing performance, including a heat-insulating outer pipe 1, a connecting outer sleeve 2, a Teflon door heat-insulating pipe 3, and a rubber connecting pipe 9. The connecting outer sleeve 2 is installed inside the heat-insulating outer pipe 1, and the Teflon door heat-insulating pipe 3 is installed inside the connecting outer sleeve 2. One end of the heat-insulating outer pipe 1 is installed with a rubber connecting pipe 9. An outer reinforcing pipe 12 is installed on the outer side of the Teflon door heat-insulating pipe 3, and a stainless steel mesh sleeve 8 is installed on the outer side of the outer reinforcing pipe 12. An installation inner groove 5 is arranged on the inner side of the heat-insulating outer pipe 1, and a sealing rubber ring 4 is installed inside the installation inner groove 5. The sealing rubber ring 4 is in close fit with the connecting outer sleeve 2, which can effectively improve the sealing performance. A circulating water inlet and outlet 7 is arranged on the top of the heat-insulating outer pipe 1, and the circulating water can enter and exit inside the heat-insulating outer pipe 1 through the circulating water inlet and outlet 7.

[0023] As Figures 1-3 shown, a sealing rubber insert 10 is installed on the top of the rubber connecting pipe 9 away from the heat-insulating outer pipe 1, and a sealing slot 11 is arranged at the bottom of the rubber connecting pipe 9 away from the heat-insulating outer pipe 1. When connecting two rubber connecting pipes 9, the sealing rubber insert 10 on one rubber connecting pipe 9 can be inserted into the sealing slot 11 on the other rubber connecting pipe 9. By covering the gap at the connection position of the two rubber connecting pipes 9 with the sealing rubber insert 10, it can prevent the circulating water from leaking out through the gap between the two rubber connecting pipes 9, thereby effectively improving the sealing performance.

[0024] As Figures 1-4 shown, reinforcing support blocks 6 are evenly installed inside the outer reinforcing pipe 12, and heat-insulating cotton 13 is evenly arranged inside the outer reinforcing pipe 12. The Teflon door heat-insulating pipe 3 has good heat resistance and cold resistance, and good corrosion resistance. When used in combination with the heat-insulating cotton 13, it can effectively improve the heat-insulating effect of the outer reinforcing pipe 12 and the Teflon door heat-insulating pipe 3.

[0025] Working principle:

[0026] When in use, the connecting outer sleeve 2 can be connected to external connecting devices such as joints, so that liquids and gases enter the Teflon door heat-insulating pipe 3 through the connecting outer sleeve 2, and the circulating water can enter and exit inside the heat-insulating outer pipe 1 through the circulating water inlet and outlet 7;

[0027] When it is necessary to connect two groups of Teflon gate insulating pipes 3, the two groups of rubber connecting pipes 9 can be closely attached to each other so that the two groups of Teflon gate insulating pipes 3 are connected. Then, the sealing rubber insert 10 on one group of rubber connecting pipes 9 is inserted into the sealing slot 11 on the other group of rubber connecting pipes 9. By using the sealing rubber insert 10 to block the gap at the connection position of the two groups of rubber connecting pipes 9, it is possible to prevent the circulating water from leaking out through the gap between the two groups of rubber connecting pipes 9, thus effectively improving the sealing performance.

[0028] During use, the stainless steel mesh sleeve 8 can reinforce the outside of the Teflon gate insulating pipe 3. When a relatively large impact force is applied locally to the reinforcing outer pipe 12, the reinforcing outer pipe 12 can evenly disperse the impact force to multiple groups of reinforcing support blocks 6. It can not only be supported by the reinforcing support blocks 6, but also the impact force can be evenly transmitted to different positions of the Teflon gate insulating pipe 3 through multiple groups of reinforcing support blocks 6, making the forces on different positions of the Teflon gate insulating pipe 3 uniform and avoiding the Teflon gate insulating pipe 3 from breaking due to excessive local stress.

[0029] At the same time, the Teflon gate insulating pipe 3 has good heat resistance, cold resistance and corrosion resistance. When used in conjunction with the heat insulating cotton 13, it can effectively improve the heat insulation effect of the reinforcing outer pipe 12 and the Teflon gate insulating pipe 3.

[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
