Technical Field

The principle of high temperature resistance of the gas pipe in the above scheme is usually: a high-temperature resistant layer made of fire-resistant and heat-insulating material is covered on the outside of the pipeline.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a household heat-resistant and safe gas pipe, comprising a pipe body 1, wherein the pipe body 1 comprises a gas pipe 17 and a cooling pipe, wherein the gas pipe 17 is located in the inner cavity of the cooling pipe, the gas pipe 17 and the cooling pipe are connected via a support ring 19, and the outer surface of the gas pipe 17 is evenly and fixedly connected with the support ring 19, the outer surface of the gas pipe 17 is wrapped with an isolation pad 18, the material of the isolation pad 18 can be rubber, and through the provision of the isolation pad, the gas pipe 17 can be protected, the risk of leakage of the gas pipe 17 can be reduced, and the reliability of the gas pipe when in use can be improved.

[0027] The cooling pipe includes an outer pipe 20 and an inner pipe. The inner pipe is located in the inner cavity of the outer pipe 20. The outer pipe 20 and the inner pipe are connected by a support mesh ring 21, and the outer wall of the inner pipe is evenly fixed with the support mesh ring 21. Through the setting of the support mesh ring 21, the support mesh ring 21 will not affect the flow of cooling water in the cooling pipe while connecting the inner pipe and the outer pipe 20.

[0028] The outer surface of the cooling pipe is wrapped with a protective pipe 22, which can protect the cooling pipe. The outer pipe 20 is fixedly connected to the inner wall of the protective pipe 22, and the material of the protective pipe 22 can be fire-resistant and heat-insulating material.

[0029] From the above description of the pipeline body 1, it can be seen that the gas pipe has the functions of passive cooling and active cooling when in use. When the temperature continues to rise, water can flow in the cooling pipe to actively cool the gas pipe 17, thereby avoiding the high temperature environment of the outer diameter from affecting the gas in the gas pipe 17, reducing the possibility of the gas pipe exploding due to high temperature, and improving the safety of the gas pipe in a high temperature environment, making it suitable for home use.

[0030] One end of the pipe body 1 is provided with a connection joint 1, and the other end of the pipe body 1 is provided with a connection joint 2.

By setting the threaded tube 23, the sealing sheet and the threaded tube 27, the sealing performance of the connecting joint 1 and the pipeline body 1 can be increased.

[0032] The fixed tube 2 is evenly provided with connecting holes 5. When the fixed tube 2 and the pipeline body 1 are threadedly connected, the inner cavity of the connecting hole 5 is in a connected state with the inner cavity of the cooling tube, and a push rod 7 is fixed in the middle of the inner cavity of the connecting hole 5.

The sealing plate 6 moves in the inner cavity of the connecting hole 5 close to the pipeline body 1. When an external force is applied, the sealing plate 6 can move in the inner cavity of the connecting hole 5 to release the restriction on the sealing plate 6. The rebound force of the spring 25 can push the sealing plate 6 so that the sealing plate 6 can fit tightly with the inner wall of the connecting hole 5. At this time, the sealing plate 6 can seal the inner cavity of the connecting hole 5.

[0033] The connecting joint 2 includes a fixed tube 29 threadedly connected to the other end of the pipeline body 1. The inner cavity of the fixed tube 29 is a convex structure. The inner diameter of one end of the fixed tube 29 is the same as the inner diameter of the pipeline body 1, and the inner diameter of the other end of the fixed tube 29 is adapted to the outer diameter of the pipeline body 1.

[0034] The outer ring of the fixed tube 29 is fixedly connected with a sealing tube 10, and the fixed tube 29 is located in the inner cavity of the sealing tube 10. The distance between the end of the sealing tube 10 away from the pipeline body 1 and the fixed tube 29 is the same as the distance between the fixed ring 13 and the end of the fixed tube 2 away from the pipeline body 1. The end of the sealing tube 10 away from the pipeline body 1 is fixedly connected with a fixing ring 211, and the fixing ring 211 is located on the side of the fixed tube 29 away from the pipeline body 1. The distance between the fixing ring 211 and the fixed tube 29 is the same as the distance between the fixing ring 3 and the fixed tube 2 away from the pipeline body 1. When the fixing ring 3 is in contact with the fixing ring 211, the fixed tube 2 and the fixed tube 29 can fit tightly.

[0035] The fixing ring 1 3 is connected to the fixing ring 2 11 by bolts 14. The outer ring of the fixing ring 1 3 is evenly provided with through holes adapted to the bolts 14. The bolts 14 are fixedly connected to the fixing ring 2 11. The outer ring of the bolt 14 is threadedly connected with a nut.

The inner cavity of the slot 13 is connected with a sealing plate 2 12 through a spring 24. The end of the sealing plate 16 and the end of the slot 13 away from the pipe body 1 are both provided with leakage holes. When the slot 13 is inserted into the inner cavity of the connecting hole 5, the slot 13 can squeeze the sealing plate 16 so that the sealing plate 16 is close to the pipe body, and the push rod 7 can squeeze the sealing plate 12 so that the sealing plate 12 is close to the pipe body 1. When the slot 13 is fully inserted into the inner cavity of the connecting hole 5, the sealing plate 12 can enter the end of the connecting hole 2 close to the pipe body 1. At this time, the inner cavities of the two adjacent cooling tubes are in a connected state.

[0037] A water inlet hole is provided at the top of one end of a connecting hole 15 near the pipeline body 1, and another water inlet hole is provided at the top of one end of a connecting hole 2 near the pipeline body 1. The inner cavity of the water inlet hole is threadedly connected with a sealing plug 4 or a water supply pipe 15, and an electric ball valve 16 is provided on one side of the water supply pipe 15. Through the arrangement of the water inlet hole, when the sealing plate 16 is tightly fitted with the inner wall of the connecting hole 1, the sealing plate 16 can be located on the side of the water inlet hole away from the pipeline body 1, and when the sealing plate 2 12 is tightly fitted with the inner wall of the slot 13, the sealing plate 2 12 is located at the end of the other water inlet hole away from the pipeline body.

When the connecting joint 1 and the connecting joint 2 are connected, the inner cavities of the two adjacent cooling pipes are in a connected state, and cooling water can be injected into the cooling pipe of the pipeline body through the water supply pipe 15, which is convenient for actively cooling the gas pipe.

[0038] In some embodiments of the present application, the electric ball valve 16 is controlled by a temperature control switch. When the temperature around the gas pipeline is abnormally high, the electric ball valve 16 is in an open state, and municipal tap water can enter the cooling pipe through the water supply pipe 15 to cool the gas pipeline.

[0039] A clamp ring 26 is fixed to one end of the fixed tube 2 9 away from the pipeline body 1, and a sealing groove 8 is provided at one end of the fixed tube 1 2 away from the pipeline body 1. The clamp ring 26 is adapted to the sealing groove 8, and the slot 13 is located between the clamp ring 26 and the sealing tube 10.
