Description

Technical Field

[0001] This utility model relates to the technical field of pipeline pressure stabilization, and in particular to a refrigerant circulation pressure stabilization device for a cold and heat source station. Background Technology

[0002] A refrigerant supply station is a facility used to provide refrigerant and heat transfer fluids, widely used in centralized cooling and heating systems. During refrigerant circulation, factors such as flow rate changes, temperature fluctuations, and equipment start-up and shutdown can cause fluctuations in refrigerant delivery pressure (too high or too low), affecting the effectiveness of centralized cooling. Therefore, a pressure stabilizing device is needed to maintain the refrigerant output pressure within a set range to prevent abnormal pressure from affecting the cooling effect. In the prior art, a utility model patent with patent application number 202321257690.X discloses a pressure stabilizing system and a cooling circulation pressure stabilizing system, which mainly consists of pipes, pressure-boosting valves, pressure-reducing valves, and expansion valves. It maintains stable fluid pressure within the pipes by pressurizing or depressurizing them. However, it has the following problems during use: it only regulates the fluid pressure within the pipes and cannot filter out solid impurities in the fluid. These solid impurities can also affect the fluid's transport within the pipes. Therefore, the aforementioned prior art device is inconvenient to use and has poor practicality. Thus, a refrigerant circulation pressure stabilizing device with filtration function is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a refrigerant circulation pressure stabilizing device for cold and heat source stations that can not only regulate water pressure but also filter out solid impurities in the refrigerant fluid, preventing solid impurities in the fluid from clogging external delivery pipelines, ensuring fluid delivery efficiency, and is easy to use and highly practical.

[0004] This utility model discloses a refrigerant circulation and pressure stabilizing device for a cold and heat source station, comprising a base plate, a supply pipe, an output pipe, and a support. The output end of the supply pipe is connected to the output pipe, and both the supply pipe and the output pipe are mounted on the base plate via the support. It also includes a pressure gauge, a pressure stabilizing mechanism, and a filter mechanism. The pressure gauge is mounted on the output pipe, and the output end of the output pipe is connected to the filter mechanism, which performs filtration. The output pipe is equipped with a pressure stabilizing mechanism, which stabilizes the fluid pressure. The input end of the supply pipe is connected to the refrigerant delivery port of the cold and heat source station, the output end of the filter mechanism is connected to an external delivery pipeline, and the pressure gauge and pressure regulating mechanism are both connected to an external controller. Operators pre-load preset parameters into the controller. The pressure is controlled by a pressure gauge. When refrigerant is supplied to the outside through a cold and heat source station, the refrigerant is delivered to the output pipe via the supply pipe. Then, the pressure gauge detects the delivery pressure of the refrigerant in the output pipe and transmits the delivery pressure to the controller. The controller then adjusts the delivery pressure of the refrigerant in the output pipe according to the delivery pressure detected by the pressure gauge, so that the delivery pressure of the refrigerant in the output pipe is maintained within the specified range. Afterward, the refrigerant is filtered by the filtration mechanism to remove solid impurities before being delivered to the external pipeline. It can not only regulate water pressure, but also filter out solid impurities in the refrigerant fluid, preventing solid impurities in the fluid from clogging the external delivery pipeline, ensuring the fluid delivery efficiency, and is convenient to use and highly practical.

[0005] Preferably, the filtration mechanism includes a U-shaped tube, a water supply pipe, a drain pipe, and a backflushing mechanism. The left end of the U-shaped tube is connected to the output end of the output pipe, and the right end of the U-shaped tube is connected to the water supply pipe. A drain pipe connected to the U-shaped tube is provided at the lower part of the U-shaped tube, and a valve is provided on the drain pipe. A filter screen is provided in the U-shaped tube, located on the right side of the drain pipe. The backflushing mechanism is installed on the water supply pipe and has a backflushing function. The output end of the water supply pipe is connected to the external refrigerant delivery pipeline. When the refrigerant is delivered to the U-shaped tube through the output pipe, solid impurities in the refrigerant fluid are filtered out by the filter screen. Then, the refrigerant fluid is delivered to the external delivery pipeline through the water supply pipe, avoiding solid impurities from clogging the external delivery pipeline. This method is convenient to use and has high reliability and practicality.

[0006] Preferably, the backflushing mechanism includes valve A, valve B, a high-pressure water pump, and a flushing pipe. Valve A and valve B are respectively installed on the output pipe and the water supply pipe. The output end of the high-pressure water pump is connected to the flushing pipe, and the flushing pipe is connected to the water supply pipe. The input end of the high-pressure water pump is connected to an external water supply mechanism. When it is necessary to clean the solid impurities on the filter screen, the collection box is placed below the drain pipe. First, valves A and B are closed, then the valves on the drain pipe are opened, and then the high-pressure water pump is turned on, allowing external water to enter the water supply pipe through the high-pressure water pump and the flushing pipe. Then, the water enters the U-shaped pipe through the water supply pipe, and then the water flows backward through the filter screen in the U-shaped pipe, washing off the solid impurities attached to the filter screen. The washed solid impurities and water are discharged together into the collection box through the drain pipe, which facilitates the washing of the filter screen in the U-shaped pipe.

[0007] Preferably, the pressure stabilizing mechanism includes a storage tank, a pressure relief pipe, a delivery pump A, and a discharge pipe. The storage tank is mounted on a base plate and has a chamber inside. The upper and lower ends of the pressure relief pipe are connected to the output pipe and the storage tank, respectively. A solenoid valve is installed on the pressure relief pipe. The input end of the delivery pump A is connected to the chamber of the storage tank, and the output end of the delivery pump A is connected to the output pipe through the discharge pipe. Both the solenoid valve on the pressure relief pipe and the delivery pump A are connected to an external controller. When the water pressure in the output pipe is too high, the controller opens the solenoid valve on the pressure relief pipe, allowing some of the refrigerant fluid in the output pipe to enter the storage tank through the pressure relief pipe for storage, thereby reducing the pressure of the refrigerant fluid in the output pipe. When the refrigerant fluid pressure in the output pipe is insufficient, the valve on the pressure relief pipe is closed, and the delivery pump A is opened, allowing the refrigerant fluid in the storage tank to enter the output pipe through the delivery pump A and the discharge pipe, thereby increasing the pressure of the refrigerant fluid in the output pipe and ensuring that the output pipe delivers refrigerant fluid at a stable pressure.

[0008] Preferably, it also includes a support frame, a transfer pump B, an inlet pipe, and a drain pipe. The support frame is mounted on the base plate, and the transfer pump B is fixedly mounted on the support frame. The input end of the transfer pump B is connected to the supply pipe through the inlet pipe, and the output end of the transfer pump B is connected to the output pipe through the drain pipe. When the pressure in the output pipe is insufficient, and the transfer pump A cannot meet the water pressure in the output pipe, the transfer pump B is turned on, so that the refrigerant fluid in the supply pipe is transported to the output pipe through the inlet pipe, the transfer pump B, and the drain pipe, thereby promoting the transport of the refrigerant fluid in the supply pipe to the output pipe and increasing the refrigerant fluid transport pressure in the output pipe.

[0009] Preferably, the storage tank is provided with an insulation layer and a thermometer; the above arrangement reduces the heat loss of the refrigerant fluid in the storage tank and facilitates the observation of the temperature of the refrigerant fluid in the storage tank.

[0010] Preferably, the liquid storage tank is provided with multiple cooling plates, the cooling ends of which are embedded in the inner wall of the liquid storage tank, and the heat dissipation ends of which are located on the outer side of the liquid storage tank. When the temperature of the refrigerant fluid in the liquid storage tank is too high, the multiple cooling plates are opened to cool down the liquid storage tank, thereby cooling down the refrigerant fluid in the liquid storage tank and ensuring the temperature of the refrigerant fluid.

[0011] Compared with the prior art, the advantages of this utility model are: it can not only regulate water pressure, but also filter out solid impurities in the refrigerant fluid, thus preventing solid impurities in the fluid from clogging the external delivery pipeline, ensuring the fluid delivery efficiency, and is convenient to use and highly practical.

The output end of the liquid supply pipe 2 is connected to the output pipe 3. Both the liquid supply pipe 2 and the output pipe 3 are mounted on the base plate 1 via the bracket 4. The pressure gauge 5 is mounted on the output pipe 3. The output end of the output pipe 3 is connected to the filter mechanism, which has a filtering function. A pressure stabilizing mechanism is installed on the output pipe 3, which has the function of stabilizing fluid pressure. The input end of the liquid supply pipe 2 is connected to the refrigerant delivery port of the cold and heat source station. The output end of the filter mechanism is connected to the external delivery pipeline. The pressure gauge 5 and the pressure regulating mechanism are both connected to an external controller. The operator prepares the controller in advance. The system delivers refrigerant at a preset pressure. When refrigerant is supplied to the outside via the cold / heat source station, it is delivered to the output pipe 3 through the supply pipe 2. Then, the pressure gauge 5 detects the refrigerant delivery pressure in the output pipe 3 and transmits it to the controller. The controller then adjusts the refrigerant delivery pressure in the output pipe 3 according to the pressure gauge 5, keeping it within a specified range. Afterward, the refrigerant is filtered by the filtration mechanism to remove solid impurities before being delivered to the external pipeline. This system not only regulates water pressure but also filters out solid impurities in the refrigerant fluid, preventing blockage of the external pipeline by these impurities, ensuring efficient fluid delivery, and offering ease of use and high practicality.

[0021] like Figure 1 and Figure 5 The filtration mechanism includes a U-shaped pipe 6, a water supply pipe 7, a drain pipe 8, and a backflushing mechanism. The left end of the U-shaped pipe 6 is connected to the output end of the output pipe 3, and the right end of the U-shaped pipe 6 is connected to the water supply pipe 7. A drain pipe 8 is installed at the bottom of the U-shaped pipe 6 and is connected to the drain pipe 8. A valve is installed on the drain pipe 8. A filter screen is installed in the U-shaped pipe 6 and is located on the right side of the drain pipe 8. The backflushing mechanism is installed on the water supply pipe 7 and has a backflushing function. The output end of the water supply pipe 7 is connected to the external refrigerant delivery pipeline. When the refrigerant is delivered to the U-shaped pipe 6 through the output pipe 3, solid impurities in the refrigerant fluid are filtered out through the filter screen. Then, the refrigerant fluid is delivered to the external delivery pipeline through the water supply pipe 7, which avoids solid impurities clogging the external delivery pipeline. It is convenient to use and has high reliability and practicality.

[0022] like Figure 1 , Figure 4 and Figure 5The backwashing mechanism includes valve A9, valve B10, high-pressure water pump 11, and flushing pipe 12. Valve A9 and valve B10 are installed on output pipe 3 and water supply pipe 7, respectively. The output end of high-pressure water pump 11 is connected to flushing pipe 12, and flushing pipe 12 is connected to water supply pipe 7. The input end of high-pressure water pump 11 is connected to an external water supply mechanism. When it is necessary to clean the solid impurities on the filter screen, the collection box is placed below the drain pipe 8. First, valves A9 and B10 are closed, then the valves on the drain pipe 8 are opened, and then high-pressure water pump 11 is turned on, so that external water enters the water supply pipe 7 through high-pressure water pump 11 and flushing pipe 12. Then, the water enters the U-shaped pipe 6 through the water supply pipe 7, and then the water flows backward through the filter screen in the U-shaped pipe 6, washing off the solid impurities attached to the filter screen. The washed solid impurities and water are discharged into the collection box through the drain pipe 8, which facilitates the washing of the filter screen in the U-shaped pipe 6.

[0023] like Figure 1 The pressure stabilizing mechanism includes a storage tank 13, a pressure relief pipe 14, a delivery pump A15, and a discharge pipe 16. The storage tank 13 is mounted on the base plate 1 and has a chamber inside. The upper and lower ends of the pressure relief pipe 14 are connected to the output pipe 3 and the storage tank 13, respectively. A solenoid valve is installed on the pressure relief pipe 14. The input end of the delivery pump A15 is connected to the chamber of the storage tank 13, and the output end of the delivery pump A15 is connected to the output pipe 3 through the discharge pipe 16. The solenoid valve on the pressure relief pipe 14 and the delivery pump A15 are both connected to an external controller. When the output pipe... When the water pressure in pipe 3 is too high, the controller opens the solenoid valve on the pressure relief pipe 14, allowing some of the refrigerant fluid in the output pipe 3 to enter the storage tank 13 through the pressure relief pipe 14, thus reducing the pressure of the refrigerant fluid in the output pipe 3. When the pressure of the refrigerant fluid in the output pipe 3 is insufficient, the controller closes the valve on the pressure relief pipe 14 and opens the delivery pump A15, allowing the refrigerant fluid in the storage tank 13 to enter the output pipe 3 through the delivery pump A15 and the discharge pipe 16, thus increasing the pressure of the refrigerant fluid in the output pipe 3 and ensuring that the output pipe 3 delivers refrigerant fluid at a stable pressure.

The input end of the transfer pump B18 is connected to the supply pipe 2 through the inlet pipe 19, and the output end of the transfer pump B18 is connected to the output pipe 3 through the drain pipe 20. When the pressure in the output pipe 3 is insufficient, and the transfer pump A15 cannot meet the water pressure in the output pipe 3, the transfer pump B18 is turned on, so that the refrigerant fluid in the supply pipe 2 is transported to the output pipe 3 through the inlet pipe 19, the transfer pump B18, and the drain pipe 20, thereby promoting the transfer of the refrigerant fluid in the supply pipe 2 to the output pipe 3 and increasing the refrigerant fluid delivery pressure in the output pipe 3.

[0025] The liquid storage tank 13 is equipped with an insulation layer and a thermometer. The above-mentioned configuration reduces the heat loss of the refrigerant fluid in the liquid storage tank 13 and facilitates the observation of the temperature of the refrigerant fluid in the liquid storage tank 13.

The cooling ends of the multiple cooling plates are embedded in the inner wall of the liquid storage tank 13, and the heat dissipation ends of the multiple cooling plates are located on the outer side of the liquid storage tank 13. When the temperature of the refrigerant fluid in the liquid storage tank 13 is too high, the multiple cooling plates are opened to cool down the liquid storage tank 13, thereby cooling down the refrigerant fluid in the liquid storage tank 13 and ensuring the temperature of the refrigerant fluid.

[0028] It should be added that: all electrical equipment in this case is connected to an external controller, which coordinates and controls the operation of each piece of electrical equipment.
