Description

Technical Field

[0001] The present application relates to the technical field of water supply devices, and particularly to a purified water supply pipeline. Background Art

[0002] In the pharmaceutical industry, the purified water generated by the pharmaceutical water system can flow into the water-using point through the purified water supply pipeline to clean the instruments. When cleaning the instruments, the instruments in some special working conditions require the purified water for cleaning the instruments to be in a low-temperature state to avoid damaging the quality of the products.

[0003] However, the purified water produced by the pharmaceutical water system is usually normal-temperature purified water, which results in that the purified water produced by the pharmaceutical water system cannot meet the requirements for cleaning low-temperature instruments in special working conditions. Summary of the Invention

[0004] Based on this, it is necessary to provide a purified water supply pipeline for the above problems. The purified water supply pipeline can reduce the temperature of the purified water during the process of transporting the purified water to the water-using point, so that the purified water reaching the water-using point can meet the requirements for cleaning low-temperature instruments in special working conditions.

[0005] Its technical solution is as follows:

[0006] A purified water supply pipeline includes a water supply pipeline, and the water supply pipeline includes:

[0007] A heat exchanger, which is provided with a high-temperature channel and a low-temperature channel;

[0008] A first water pipe, which is communicated with the high-temperature channel, and the first water pipe is used to be communicated with the pharmaceutical water system;

[0009] A second water pipe, which is communicated with the high-temperature channel, and the second water pipe is used to be communicated with the water-using point, and the second water pipe is provided with a first temperature sensor;

[0010] A cooling pipeline, which includes an inlet cooling pipe and an outlet cooling pipe. The inlet cooling pipe is communicated with the outlet cooling pipe through the low-temperature channel. The inlet cooling pipe is used to transport a cooling solution to the low-temperature channel, and the outlet cooling pipe is used to receive the cooling solution flowing out of the low-temperature channel. The outlet cooling pipe is provided with a first regulating valve, and the first regulating valve is electrically connected to the first temperature sensor. The first regulating valve can adjust the opening degree according to the temperature value detected by the first temperature sensor.

[0011] In the above purified water supply pipeline, the first water pipe is connected to the pharmaceutical water system and the high-temperature channel of the heat exchanger, and the second water pipe is connected to the high-temperature channel and the water use point. This enables the purified water produced by the pharmaceutical water system to be transported to the water use point through the supply pipeline for cleaning the equipment. Since the inlet cooling pipe in the cooling pipeline is connected to the outlet cooling pipe through the low-temperature channel of the heat exchanger, when the cooling solution flows into the cooling pipeline from the inlet cooling pipe, the cooling solution can flow into the low-temperature channel through the inlet cooling pipe and flow out of the low-temperature channel through the outlet cooling pipe. Therefore, when normal-temperature purified water flows through the high-temperature channel of the heat exchanger and low-temperature cooling solution flows through the low-temperature channel of the heat exchanger, the cooling solution can be used as a refrigerant to cool the purified water to reduce its temperature. Among them, since the first temperature sensor provided on the second water pipe is connected to the first regulating valve of the cooling pipeline, the first temperature sensor can timely detect the temperature of the cooled purified water, so that the first regulating valve can adjust its opening according to the detected temperature value to regulate the flow rate of the cooling solution in the cooling pipeline, thereby ensuring that the cooling solution can cool the purified water to the required range at the heat exchanger, and further ensuring that the purified water reaching the water use point can meet the requirements of low-temperature cleaning of equipment in special working conditions. Therefore, this purified water supply pipeline can reduce the temperature of the purified water during the process of transporting it to the water use point, so that the purified water reaching the water use point can meet the requirements of low-temperature equipment cleaning in special working conditions, thus effectively ensuring the quality of the product.

[0012] The technical solution will be further described below:

[0013] In one embodiment, the supply pipeline includes a second temperature sensor.

[0032] Referring to Figure 1 and Figure 2 , a purified water supply pipeline provided by an embodiment of the present application includes a water supply pipeline 10, and the water supply pipeline 10 includes a heat exchanger 7, a first water pipe 1, a second water pipe 4 and a cooling pipeline 8. Among them:

[0033] The heat exchanger 7 is provided with a high-temperature channel and a low-temperature channel. The first water pipe 1 is communicated with the high-temperature channel. The first water pipe 1 is used to communicate with the water system in the pharmaceutical industry. The second water pipe 4 is communicated with the high-temperature channel. The second water pipe 4 is used to communicate with the water usage point 5. The second water pipe 4 is provided with a first temperature sensor 3. The cooling pipeline 8 includes an inlet liquid cooling pipe 81 and an outlet liquid cooling pipe 88. The inlet liquid cooling pipe 81 is communicated with the outlet liquid cooling pipe 88 through the low-temperature channel. The inlet liquid cooling pipe 81 is used to convey a cooling solution to the low-temperature channel. The outlet liquid cooling pipe 88 is used to receive the cooling solution flowing out of the low-temperature channel. The outlet liquid cooling pipe 88 is provided with a first regulating valve 86. The first regulating valve 86 is electrically connected to the first temperature sensor 3. The first regulating valve 86 can adjust the opening degree according to the temperature value detected by the first temperature sensor 3.

[0034] In the above-mentioned purified water supply pipeline 10, the first water pipe 1 is connected to the pharmaceutical water system and the high-temperature channel of the heat exchanger 7, and the second water pipe 4 is connected to the high-temperature channel and the water usage point 5. This enables the purified water produced by the pharmaceutical water system to be transported to the water usage point 5 through the supply pipeline 10 for cleaning the instruments. Since the inlet liquid cooling pipe 81 in the cooling pipe 8 is connected to the outlet liquid cooling pipe 88 through the low-temperature channel of the heat exchanger 7, when the cooling solution flows into the cooling pipe 8 from the inlet liquid cooling pipe 81, the cooling solution can flow into the low-temperature channel through the inlet liquid cooling pipe 81 and flow out of the low-temperature channel through the outlet liquid cooling pipe 88. Therefore, when the normal-temperature purified water flows through the high-temperature channel of the heat exchanger 7 and the low-temperature cooling solution flows through the low-temperature channel of the heat exchanger 7, the cooling solution can be used as a refrigerant to cool the purified water to reduce the temperature of the purified water. Among them, since the first temperature sensor 3 provided on the second water pipe 4 is connected to the first regulating valve 86 of the cooling pipe 8, the first temperature sensor 3 can timely detect the temperature of the cooled purified water, so that the first regulating valve 86 can adjust its opening degree according to the detected temperature value to regulate the flow rate of the cooling solution in the cooling pipe 8, thereby ensuring that the cooling solution can cool the purified water to the required range at the heat exchanger 7, and further ensuring that the purified water reaching the water usage point 5 can meet the requirements of low-temperature cleaning of instruments in special working conditions. Therefore, the purified water supply pipeline 100 can reduce the temperature of the purified water during the process of transporting the purified water to the water usage point 5, so that the purified water reaching the water usage point 5 can meet the requirements of low-temperature instrument cleaning in special working conditions, thereby effectively ensuring the quality of the product.

[0035] Optionally, the cooling solution can be a liquid with low-temperature characteristics, such as a low-temperature ethylene glycol solution.

[0036] Optionally, the first regulating valve 86 includes a pneumatic regulating valve. The pneumatic regulating valve has the characteristics of simple control, fast response, and high safety factor. Therefore, setting the first regulating valve 86 as a pneumatic regulating valve is beneficial to ensuring the safety performance of the purified water supply pipeline 100 and simplifying the structure of the purified water supply pipeline 100.

[0037] In one embodiment, as Figure 1 and Figure 2 shown, the supply pipeline 10 includes a second temperature sensor 2. The second temperature sensor 2 is provided on the first water pipe 1 and is electrically connected to the first regulating valve 86. The first regulating valve 86 can adjust the opening degree according to the temperature value detected by the second temperature sensor 2. In this way, the second temperature sensor 2 can detect the temperature of the purified water before cooling, and the first temperature sensor 3 can detect the temperature of the purified water after cooling. Therefore, the first regulating valve 86 can adjust its opening degree to a suitable position according to the temperature difference of the purified water before and after cooling, so as to ensure that the purified water can be cooled to the required temperature range and the cooling capacity of the cooling solution can be fully utilized, avoiding waste of cooling resources.

[0038] In one embodiment, as Figure 1 and Figure 2 shown, the liquid inlet cooling pipe 81 is provided with a first control valve 85, and the first control valve 85 is used to control the on-off of the liquid inlet cooling pipe 81. In this way, when it is not necessary to clean the instrument or reduce the purified water, the flow of the cooling solution in the cooling pipe 8 can be stopped, thereby effectively avoiding the waste of cooling resources and reducing costs.

[0039] Further, in one embodiment, as Figure 1 and Figure 2 shown, the liquid outlet cooling pipe 88 is provided with a second control valve 87, and the second control valve 87 is used to control the on-off of the liquid inlet cooling pipe 81. The cooling pipe 8 includes a return cooling pipe 84, and the return cooling pipe 84 is communicated with both the liquid inlet cooling pipe 81 and the liquid outlet cooling pipe 88. The first control valve 85 is arranged on the liquid inlet cooling pipe 81 between the return cooling pipe 84 and the low-temperature channel, and the second control valve 87 is arranged on the liquid outlet cooling pipe 88 between the return cooling pipe 84 and the low-temperature channel. The return cooling pipe 84 is provided with a third control valve 83, and the third control valve 83 is used to control the on-off of the return cooling pipe 84. In this way, when both the first control valve 85 and the second control valve 87 are closed and the third control valve 83 is opened, the cooling solution in the liquid inlet cooling pipe 81 can flow into the liquid outlet cooling pipe 88 through the return cooling pipe 84. When both the first control valve 85 and the second control valve 87 are opened and the third control valve 83 is closed, the cooling solution in the liquid inlet cooling pipe 81 can flow into the liquid outlet cooling pipe 88 through the low-temperature channel, so that the cold air solution can cool the purified water flowing through the heat exchanger 7. Therefore, with the cooperation of the first control valve 85, the second control valve 87 and the third control valve 83, the flow path of the cooling solution can be switched as needed, so that it is possible to select whether to use the cooling solution to cool the purified water as needed.

[0040] Schematically, as Figure 1 and Figure 2 shown, the first regulating valve 86 is arranged on the liquid outlet cooling pipe 88 between the return cooling pipe 84 and the low temperature, so that the first regulating valve 86 can regulate the flow rate of the cooling pipe 8 when cooling the purified water.

[0041] In one embodiment, as Figure 1 and Figure 2 shown, the liquid inlet cooling pipe 81 is provided with a pressure gauge 82, and the pressure gauge 82 is used to detect the water pressure in the liquid inlet cooling pipe 81. In this way, the flow rate of the cooling solution in the current cooling pipe 8 can be judged according to the pressure value detected by the pressure gauge 82, and thus the flow rate of the cooling solution in the cooling pipe 8 can be controlled by adjusting the water pressure, so as to ensure that the purified water can be cooled to the required temperature range and the cooling capacity of the cooling solution can be fully utilized, avoiding the waste of cooling resources.

[0042] In one embodiment, as Figure 1 andFigure 2 As shown, the number of the water supply pipes 10 is two, and the two water supply pipes 10 are arranged in parallel. In this way, the two pipes can supply water to the water consumption point 5 simultaneously to meet the flow rate requirements for instrument cleaning.

[0043] Further, in one embodiment, as Figure 1 and Figure 2 shown, the purified water supply pipeline 100 includes two second regulating valves 6. One of the second regulating valves 6 is arranged in the first water pipe 1 or the second water pipe 4 of one of the water supply pipes 10, and the other second regulating valve 6 is arranged in the first water pipe 1 or the second water pipe 4 of the other water supply pipe 10. Each second regulating valve 6 is used to regulate the flow rate of the purified water in the corresponding water supply pipe 10. In this way, the opening degrees of the second regulating valves 6 in the two water supply pipes 10 can be adjusted according to the water consumption requirements of the water consumption point 5 to control the flow rates of the purified water in the respective water supply pipes 10. In addition, when the water volume at the water consumption point 5 is uneven or there are deviations in the flow rates of the two water supply pipes 10, the opening degrees of the respective second regulating valves 6 can also be adjusted to ensure that the flow rate values of each water supply pipe 10 are the same, thereby improving the stability of the purified water supply pipeline 100. Therefore, the setting of the second regulating valves 6 can balance the flow rates of the two water supply pipes 10.

[0044] Optionally, each second regulating valve 6 includes a pneumatic regulating valve. The pneumatic regulating valve has the characteristics of simple control, fast response, and high safety factor. Therefore, setting the second regulating valve 6 as a pneumatic regulating valve is beneficial to ensuring the safety performance of the purified water supply pipeline 100 and simplifying the structure of the purified water supply pipeline 100.

[0045] Further, in one embodiment, in combination with Figure 2 shown, the purified water supply pipeline 100 includes a control panel, and the control panel is electrically connected to each second regulating valve 6. The control panel is used to adjust the opening degree of each second regulating valve 6. In this way, when the user inputs corresponding control instructions to the control panel, the control panel can adjust the opening degree of any second regulating valve 6 according to the instructions to quickly adjust the flow rate value of any water supply pipe 10. Therefore, the setting of the control panel enables the user to conveniently control the flow rate of the purified water supply pipe 10, which is beneficial to simplifying the maintenance operation and improving the user experience.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0047] The above embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
