[0001] This utility model belongs to the field of hydrophobic anti-theft technology for steam pipes, and particularly relates to a hydrophobic anti-theft device for buried steam pipes. Background Technology

[0002] When buried steam transmission pipes are affected by internal and external temperature differences, condensation is likely to form on the inner wall. The accumulation of condensation will affect the steam transmission efficiency and increase the risk of corrosion and pressure fluctuations. At the same time, the entire drainage system is susceptible to damage from external theft, affecting normal steam transmission and drainage operations. Summary of the Invention

[0006] Furthermore, the core tube is provided with a hydrophobic port that connects to the inner hydrophobic layer, and the hydrophobic port is located at the bottom of the core tube body.

[0007] Furthermore, the outer sleeve is provided with a connecting port for docking with the outer protective layer, the opening of the outer protective layer extends to the ground, and the opening of the outer protective layer remains in a normally open state.

[0008] Furthermore, a transition valve is also provided on the inner hydrophobic layer, and the transition valve is located between the drain valve and the outer protective layer.

[0014] Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 . Detailed Implementation

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] like Figure 1 and Figure 2 As shown, a condensate-proof and anti-theft device for buried steam pipes includes a core pipe 1 for transporting steam and an outer sleeve 2 covering the core pipe 1, with a protective interlayer 3 formed between the outer sleeve 2 and the core pipe 1. It also includes a condensate drain pipe 4, which has an inner condensate-proof layer 5 and an outer protective layer 6. The inner condensate-proof layer 5 connects to the core pipe 1 and is used to collect and discharge condensate within the core pipe 1. The drain outlet of the inner condensate-proof layer 5 is equipped with a drain valve 10 locked by an anti-theft component 7. The outer protective layer 6 connects to the protective interlayer 3, allowing the protective interlayer 3 to be connected to the outside environment through the outer protective layer 6. This invention utilizes the condensate drain pipe 4 to effectively drain condensate from the core pipe 1, thereby preventing condensate accumulation within the core pipe 1 and avoiding affecting steam transport efficiency. It also reduces the risk of corrosion and pressure fluctuations. Furthermore, the drain valve 10 and the anti-theft component 7 ensure the safety and normal operation of the system, improve system efficiency, reduce maintenance costs, and protect the system from external damage.

[0017] The inner hydrophobic layer 5 serves a hydrophobic function, while the outer protective layer 6 provides protection for the inner hydrophobic layer 5, ensuring the safety and stability of the hydrophobic operation.

[0018] The core tube 1 is provided with a drainage port 8 that connects to the inner hydrophobic layer 5. To facilitate the drainage of condensate, the drainage port 8 is located at the bottom of the core tube 1. The inner hydrophobic layer 5 is connected to a green belt or rainwater well so that the condensate can be safely discharged into the underground drainage system.

[0019] In this invention, the outer sleeve 2 serves to protect the core tube 1. Due to the temperature difference between the protective interlayer 3 and the outside of the outer sleeve 2, the pressure inside the protective interlayer 3 changes, becoming unbalanced with the external environment, posing a safety risk. Therefore, if... Figure 1 or Figure 2 As shown, the outer sleeve 2 is provided with a through port 9 for connecting to the outer protective layer 6. The opening of the outer protective layer 6 extends to the ground and is kept in a normally open state, so that the protective interlayer 3 maintains pressure balance with the outside world and ensures safety.

[0020] To improve hydrophobicity control, a transition valve 11 is also provided on the inner hydrophobic layer 5, which is located between the drain valve 10 and the outer protective layer 6.

[0021] The anti-theft component 7 can prevent the drainage system from being operated illegally. As a preferred option, the anti-theft component 7 is a specially designed anti-theft bolt, ensuring that only authorized personnel can perform maintenance or drainage operations.

[0022] More specifically, such as Figure 1 As shown, the drainage pipe 4 includes an inner drainage pipe 41 and an outer protective pipe 42. The internal space of the inner drainage pipe 41 is an inner drainage layer 5, and the outer protective layer 6 is formed between the inner drainage pipe 41 and the outer protective pipe 42.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
