Description

Technical Field

[0001] The present application relates to the technical field of pharmaceutical water, and in particular to a one-way water supply system. Background Art

[0002] Nowadays, in the production process of pharmaceutical factories, some water-using places such as workshops and laboratories need a small amount of softened water, cleaning water, etc. In the related art, the conventional design scheme is to use a loop water supply system to circulate purified water and water for injection and distribute them to the corresponding water-using places. However, the water pipeline required for the loop water supply system is long, the equipment investment cost is high, and the flow resistance of water in the pipeline is large, the water supply pressure is difficult to guarantee, and the required system power is high, resulting in increased operating costs. Summary of the invention

[0003] Based on this, it is necessary to provide a one-way water supply system to address the problems of high equipment investment cost and high operating cost in the prior art.

[0004] The present application provides a one-way water supply system, which comprises:

[0005] Water storage tanks;

[0006] A water delivery pipeline, the water inlet of the water delivery pipeline being connected to the water outlet of the water storage tank;

[0007] A driving water pump, wherein the driving water pump is arranged in the water delivery pipeline;

[0008] A one-way valve, the one-way valve is arranged in the water delivery pipeline and is located downstream of the driving water pump;

[0009] A pressure transmitter, the pressure transmitter is arranged in the water delivery pipeline and is located downstream of the one-way valve;

[0010] a pressure stabilizing tank, the pressure stabilizing tank being arranged in the water delivery pipeline and being located downstream of the pressure transmitter; and

[0011] A water-using place is connected to the water outlet of the water delivery pipeline.

[0012] When the one-way water supply system of this scheme is working, the softened water stored in the water storage tank is discharged and flows along the water pipeline to the driving water pump. At this time, the one-way valve is opened, and the softened water flows through the pressure transmitter and the pressure-stabilizing tank in sequence along the water pipeline at a certain pressure under the pumping of the driving water pump. Through the linkage between the pressure transmitter and the driving water pump and the pressure-stabilizing effect of the pressure-stabilizing tank, the system water supply pressure can be effectively guaranteed. Finally, the softened water is delivered to the water-using place through the water pipeline to meet the water demand. Compared with the loop water supply system of the prior art, in this scheme, the softened water can flow from the water storage tank along the water pipeline in a one-way straight line to the water-using place, which reduces the length of the water pipeline and reduces the equipment investment cost. In addition, since the water pipeline is short, the water is subject to small flow resistance, thereby ensuring the system water supply pressure, improving the water transmission efficiency, reducing the system operating power requirements, and effectively controlling the operating cost.

[0013] The technical solution of this application is further described below:

[0014] In one of the embodiments, the driving water pump is electrically connected to the pressure transmitter.

[0034] See also Figure 1 , which is a one-way water supply system 100 shown in an embodiment of the present application, which can be used in a pharmaceutical factory to transport and provide the required softened water to some water-using places 70 such as workshops and laboratories during the production process.

[0035] Exemplarily, the one-way water supply system 100 includes a water storage tank 10 , a water delivery pipeline 20 , a driving water pump 30 , a one-way valve 40 , a pressure transmitter 50 , a pressure regulating tank 60 , and a water use place 70 .

[0036] Wherein, the water storage tank 10 is a container for storing softened water, and can be made of materials such as stainless steel plates. During installation, it can be fixed on the ground by a special bracket, or it can be hung on a wall or the like by a hanger, and can be flexibly selected according to actual needs.

[0037] In order to conveniently monitor the amount of softened water stored in the water tank 10 , a transparent observation window extending in the height direction may be provided on the side wall of the water tank 10 , or a liquid level sensor may be directly installed in the water tank 10 .

[0038] The water inlet of the water supply pipeline 20 is connected to the water outlet of the water storage tank 10; the driving water pump 30 is arranged in the water supply pipeline 20; the one-way valve 40 is arranged in the water supply pipeline 20 and is located downstream of the driving water pump 30; the pressure transmitter 50 is arranged in the water supply pipeline 20 and is located downstream of the one-way valve 40; the pressure regulating tank 60 is arranged in the water supply pipeline 20 and is located downstream of the pressure transmitter 50; the water use place 70 is connected to the water outlet of the water supply pipeline 20.

[0039] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: when the one-way water supply system 100 of this solution is working, the softened water stored in the water storage tank 10 is discharged and flows along the water pipeline 20 to reach the driving water pump 30. At this time, the one-way valve 40 is opened, and the softened water flows along the water pipeline 20 with a certain pressure through the pressure transmitter 50 and the pressure-stabilizing tank 60 in sequence under the pumping of the driving water pump 30. Through the linkage between the pressure transmitter 50 and the driving water pump 30 and the pressure-stabilizing effect of the pressure-stabilizing tank 60, the water supply pressure of the system can be effectively guaranteed. Finally, the softened water is delivered to the water-using place 70 via the water pipeline 20 to meet the water demand. Compared with the loop water supply system of the prior art, in this solution, softened water can flow from the water storage tank 10 along the water supply pipeline 20 in a unidirectional radial direction to the water use place 70, which reduces the length of the water supply pipeline 20 and reduces the equipment investment cost. Moreover, since the water supply pipeline 20 is short, the flow resistance of the water is small, thereby ensuring the system water supply pressure, improving the water supply efficiency, reducing the system operating power requirement, and effectively controlling the operating cost.

[0040] On the basis of the above embodiment, the driving water pump 30 is electrically connected to the pressure transmitter 50. It is necessary to explain that the pressure transmitter 50 is a device that can convert pressure into a pneumatic signal or an electric signal for control and remote transmission. It can convert the physical pressure parameters of gas, liquid, etc. sensed by the pressure measuring element sensor into a standard electrical signal (such as 4~20mADC, etc.). For example, in this application, the pressure transmitter 50 will monitor the water pressure to generate a corresponding command signal and feed it back to the driving water pump 30, thereby providing a basis for the driving water pump 30 to adjust the power of driving the softened water to flow.

[0041] Optionally, the driving water pump 30 in the present application can be any one of a multi-stage pump, a single-stage pump, etc., which can be flexibly selected according to actual needs.

[0042] Please continue reading Figure 1 In addition, in another embodiment, the one-way water supply system 100 further includes a pressure gauge 80, which is disposed in the water delivery pipeline 20 and is located between the pressure transmitter 50 and the pressure regulating tank 60. By providing the pressure gauge 80, it is convenient for the staff to intuitively observe the real-time water supply pressure of the system, thereby facilitating the staff to adjust the water supply pressure of the system in a timely manner, and eliminating potential safety hazards caused by excessive water supply pressure.

[0043] Further, based on any of the above embodiments, the one-way water supply system 100 also includes a first control valve 90 , which is disposed in the water supply pipeline 20 and located between the water storage tank 10 and the driving water pump 30 .

[0044] The first control valve 90 is directly connected to the water outlet of the water storage tank 10. When the one-way water supply system 100 is shut down for a long time or needs to be regularly eliminated, the first control valve 90 can be opened to drain all the softened water in the system to avoid residual softened water and cause health problems.

[0045] For example, the first control valve 90 may be any one of a manual valve and an electric control valve.

[0046] Please continue reading Figure 1 In another embodiment, the one-way water supply system 100 further includes a second control valve 90a, which is disposed in the water delivery pipeline 20 and located between the first control valve 90 and the driving water pump 30. By controlling the second control valve 90a on and off, it is convenient to control whether the softened water flows into the driving water pump 30, thereby regulating the operating conditions of the one-way water supply system 100.

[0047] Furthermore, the one-way water supply system 100 further includes a third control valve 90b, which is disposed in the water delivery pipeline 20 and is located between the driving water pump 30 and the one-way valve 40. By on-off controlling the third control valve 90b, the connection or shutoff of the softened water in the water delivery pipeline 20 can be further flexibly controlled.

[0048] Please continue reading Figure 1 Furthermore, the one-way water supply system 100 further includes a sampling valve 90c, which is disposed in the water delivery pipeline 20, and is located between the one-way valve 40 and the pressure transmitter 50. The staff can regularly sample the softened water flowing through the water delivery pipeline 20 through the sampling valve 90c, so as to detect the water quality.

[0049] Please continue reading Figure 1 In addition, based on any of the above embodiments, the water use place 70 includes at least two floors 71, and each floor 71 is provided with water facilities. It can be understood that the water use place 70 may refer to a production workshop or a mobile laboratory building of a pharmaceutical factory, and different rooms on each floor 71 in the production workshop or the laboratory building are provided with water facilities. The water delivery pipeline 20 can deliver softened water to the water facilities on any floor 71 to meet the water needs of different people and different locations.

[0050] Specifically, the water-using facilities in the above embodiment include a water intake pipe 72, a water intake valve 73 and a water pool, the water inlet of the water intake pipe 72 is connected to the water outlet of the water delivery pipeline 20, the water intake valve 73 is arranged at the water outlet of the water intake pipe 72, and the water pool is arranged below the water intake valve 73. The water intake pipe 72 is directly connected to the water delivery pipeline 20, so that soft water can be directly diverted from the water delivery pipeline 20 to the water intake valve 73, and workers can use softened water by opening the water intake valve 73; the water pool installed below the water intake valve 73 can receive excess softened water flowing out of the water intake valve 73, so as to avoid the soft water from flowing out and polluting the environment and causing waste of water resources.

[0051] Preferably, the water intake pipe 72, the water intake valve 73 and the water tank are all provided in multiple numbers and are arranged one by one in a corresponding manner. In this way, a set of water facilities can be provided in different rooms to meet the water demand.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
