[0025] The utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0026] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by "up", "down", "left", "right", "inside", "outside", "top" and "bottom" are all based on the directions or positional relationships shown in the accompanying drawings. The purpose is only to facilitate the description of the present invention and simplify the description. It does not indicate or imply that the referred parts must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] like Figure 1-2 As shown, the utility model provides a compensation type explosion-proof and anti-freezing and cracking liquid supply and water supply device, comprising: a main pipeline 1, a compression compensation pipe 2, a rectifying device 3, a plurality of fixing devices 4 and a positioning block 5;

[0028] The main pipeline 1 is the basic structure of the whole device. The main pipeline 1 is a hollow cylindrical structure. The main pipeline 1 is a steel delivery pipe. The main pipeline 1 is made of carbon steel. The carbon steel material ensures that the main pipeline 1 has sufficient strength to withstand high pressure. The outer wall of the main pipeline 1 is provided with a liquid flow direction mark to facilitate construction and maintenance personnel to identify the flow direction of the fluid and ensure the normal operation of the device. A number of compression compensation tubes 2 are evenly arranged in the main pipeline 1. The compression compensation tube 2 is a hollow structure. The compression compensation tube 2 is filled with a compressed medium. The compression compensation tube 2 is made of chloroprene rubber material. This material has good elasticity and weather resistance and can remain soft in severe cold conditions. state, so that the compression compensation tube 2 can withstand certain pressure changes and adapt to temperature changes, thereby ensuring the stability of the device under different environmental conditions. Several compression compensation tubes 2 are respectively installed on the inner wall of the main pipeline 1 by the fixing device 4 to ensure that the compression compensation tube 2 will not be displaced when subjected to pressure. The compression medium in the compression compensation tube 2 is air. When the external temperature drops and causes the fluid to freeze in the main pipeline 1, the air in the compression compensation tube 2 can be compressed to provide a release space for the expansion of the fluid, thereby avoiding the risk of the main pipeline 1 bursting due to excessive fluid expansion pressure, and further improving the safety and reliability of the device;

[0029] It should be noted that the gas in the compression compensation tube 2 is replaced with nitrogen when flammable and explosive gases or liquids can be transported in the main pipeline 1. Nitrogen is a non-flammable gas with stable chemical properties. Replacing the gas in the compression compensation tube 2 with nitrogen can significantly improve the safety of the device.

[0030] A positioning block 5 and a rectifying device 3 are respectively provided on both sides of the compression compensation tube 2. The positioning block 5 is a rectangular structure. The positioning block 5 is arranged at the left end of the compression compensation tube 2. The positioning block 5 is connected to the inner wall of the main pipeline 1. The positioning block 5 plays a role in supporting and fixing the compression compensation 2, ensuring that the position of the compression compensation tube 2 is fixed, preventing the compression compensation tube 2 from sliding or twisting in the main pipeline 1, ensuring its stable position in the pipeline, helping to maintain the stable flow of the fluid in the main pipeline 1, and avoiding fluid dynamics instability and potential energy loss caused by the movement of internal components of the main pipeline 1;

[0031] The rectifying device 3 is arranged in the opposite direction of the liquid flow direction mark of the main pipeline 1. The rectifying device 3 is composed of an upper and lower part. The lower end of the rectifying device 3 is a rectangular structure, and the upper end of the rectifying device 3 is a semicircular structure. The semicircular structure is sleeved on the outer wall of the compression compensation tube 2, which helps to guide the fluid to flow smoothly through the compression compensation tube 2, avoiding turbulence and unnecessary energy loss of the fluid in the main pipeline 1. The rectangular structure is connected to the inner wall of the main pipeline 1. The rectifying device 3 combs the fluid, which helps to optimize the fluid to maintain a relatively ideal flow state in the main pipeline 1, which can not only improve the fluid transportation efficiency, but also reduce the energy loss caused by fluid instability, thereby helping to improve the energy utilization efficiency of the entire system;

[0032] Through the coordinated work of the positioning block 5 and the rectifying device 3, the compression compensation tube 2 is not only strengthened in structure, but also can maintain the optimal working state during the entire fluid transportation process.

[0033] The fixing device 4 is a circular ring structure, and a plurality of fixing devices 4 are evenly sleeved on the compression compensation tube 2 to minimize the obstruction to the fluid flow. The fixing device 4 is connected to the inner wall of the main pipeline 1 to ensure that the compression compensation tube 2 will not shift when under pressure.

[0034] The outer wall of the compression compensation tube 2 is provided with two through holes penetrating the main pipeline 1, and the through holes are respectively provided with a charging and discharging valve 6 and a pressure-limiting relief valve 7. The charging and discharging valve 6 allows the operator to manually control the charging and discharging of the compressed medium in the compression compensation tube 2. The pressure-limiting relief valve 7 can automatically open when the pressure borne by the compression compensation tube 2 exceeds the safety threshold, and release the excessive compressed medium in the compression compensation tube 2, thereby preventing the device from overloading and possible explosion risks. The charging and discharging valve 6 and the pressure-limiting relief valve 7 provide maintenance personnel with a means of managing and adjusting the pressure of the device, greatly improving the safety performance of the device.

[0035] It should be noted that, in the actual working process, the compressed medium in the compression compensation tube 2 is released through the charging and discharging valve 6, which can provide additional expansion space for the frozen fluid in the main pipeline 1, avoiding destructive pressure on the main pipeline 1 due to fluid expansion. After the compressed medium in the compression compensation 2 is released, a high-temperature medium such as hot water or steam can be injected into the compression compensation tube 2 through the charging and discharging valve 6. Due to heat transfer, the high-temperature medium will help melt the frozen fluid in the main pipeline 1. As the high-temperature medium circulates in the compression compensation tube 2, its heat will gradually be transferred to the main pipeline 1, thereby causing the frozen fluid in the main pipeline 1 to begin to melt. When the fluid in the main pipeline 1 is completely melted, the injection of the high-temperature medium can be stopped, and the charging and discharging valve 6 can be closed.

[0036] The following is a detailed introduction to the actual working scenario of a compensating explosion-proof and anti-freezing and cracking liquid supply and water supply device.

[0037] In actual working process, a compensating explosion-proof and anti-freezing cracking liquid supply water supply device adopts a compression compensation pipe 2. When the external temperature drops and causes the fluid to freeze in the main pipeline 1, the compressed medium in the compression compensation pipe 2 can be compressed to provide additional expansion space for the water in the main pipeline, thus avoiding the risk of the main pipeline bursting due to excessive water expansion pressure.

[0038] If the pressure on the compression compensation tube 2 exceeds the safety threshold, the pressure-limiting relief valve 7 will automatically open to release excess compressed medium to prevent overloading of the device and possible explosion risks. The charging and discharging valve 6 allows the operator to manually control the filling and discharge of compressed medium in the compression compensation tube 2, which provides maintenance personnel with a means to manage and adjust the pressure of the device, greatly improving the safety performance of the device. The rectifying device 3 reduces the pressure fluctuation and turbulence of the fluid before entering the compression compensation tube 2 by guiding the fluid, thereby improving the efficiency of the fluid passing through the compression compensation tube 2. The positioning block 5 ensures that the position of the compression compensation tube 2 is fixed, preventing unnecessary displacement or vibration, and helping to maintain the stable flow of the fluid in the main pipeline 1, avoiding fluid dynamic instability and potential energy loss caused by the movement of internal components of the pipeline.

[0039] It can be understood that the above-mentioned various embodiments mentioned in the present invention can be combined with each other to form a combined embodiment without violating the principle logic. Due to space limitations, the present invention will not elaborate on them.

The specific execution order of the steps should be determined by their functions and possible internal logic.
