Description

Synchronous valve operation independent of hydrostatic pressure Technical Field The present invention relates to energy use in a start-stop mechanism when circulating fluid to an elevated vessel in general, and more particularly to a method for operating a start-stop mechanism without any influence of hydrostatic pressure, wherein a plurality of input connections and output connections are operatively connected to at least one closed vessel, each connection having at least one input and at least one output operatively connected to a pressurized system, and each connection having at least one input and at least one output operatively connected to another pressurized system having a pressure differential. Background From prior art WO2022186699A1 and non-resistance circulation to the elevated vessel, one should involve conventional start-stop mechanism (valve) operation that regulates, directs or controls the flow of fluid in the circulation loop. From the prior art, a circulation system should be mentioned, wherein the main operation is to transport the fluid upwards. When using start-stop mechanisms (valves) for such cycles, they will be subjected to hydrostatic pressure and thus to friction and energy use during their operation. One set of methods describes a start-stop mechanism (valve) in which the hydrostatic pressure that can affect the start-stop mechanism is defined by a flow or circulation in the horizontal plane, where the flow is generated by a circulation unit for the purpose of recirculation or regulation of the flow to the consumer. The most notable variant of the method is when fluid is circulated from a source container to a container in an elevated position relative to the source container, wherein the fluid flows from the source container into the elevated container in a non-resistive manner. In such operation, the start-stop mechanism (valve) in the circulation loop will be subjected to hydrostatic pressure, which is defined by the height between the valve and the liquid level in the elevated vessel or by the height between the valve and the liquid level in the source vessel. The pressure may be significant and is generally defined by the term pump head (elevated height), by the difference between the liquid level in the source vessel and the liquid level in the elevated vessel, according to the prior art. The liquid level in the source vessel defines a reference point for the height. This height gives a pressure of about 100 mbar/m. These methods are known as normal fluid circulation methods, wherein the aim is to replace the fluid in the elevated vessel. The main problems of valve operation in cycling to the raised position are: 1. The start-stop mechanism is subjected to a hydrostatic pressure of about 100 mbar/m (10000 pascals). 2. Due to friction in the start-stop mechanism (present due to hydrostatic pressure), the start-stop mechanism will have to operate at a very high energy level. 3. In the case of many start-stop operations within a certain time frame, the energy usage will multiply and be too large. 4. The start-stop mechanism is subjected to pressure (typically pi)R2, where R is the pipe radius). At higher (duct) sizes, the force acting on the start-stop mechanism will increase with increasing area. This requires more energy usage for higher operating speeds or slower speeds to save energy usage during its operation. As an example, valve operation that is not subject to hydrostatic pressure will solve a number of problems: the energy usage will be low. When the flow is started and stopped with the start-stop mechanism, reduced friction will enable faster rotation and will enable higher frequencies. A high frequency start-stop switch in the valve will prevent the water flow from stopping. Prior Art From the prior art, an important observation is that conventional valves operate mainly under pressure. Operating the valve under pressure is a high resistance operation due to the force on the valve area. The force is generally defined as f=pA, and in the case of a meter height and 10000 pascals (100 mbar), this pressure will apply a force of about 32kgf to a 200mm diameter valve opening. This energy would require that conventional valves use a significant amount of energy to open or close, or even remain in place. The height increases and the energy use increases. Many have attempted to address how water is transported from a low pressure system to a high pressure system. Mainly, they try to overcome the force equation f=p at energy equation e= mgh or from pressureObvious disorders in a. From the first formula e= mgh, it is not possible to change any parameters to reduce the energy consumption when water is delivered upwards, and from f=pIt appears that it is more likely to manipulate the pressure or area to be able to overcome gravity. One invention that directly addresses the pressure for vertically moving water is WO2010031162A1, which uses a pressure differential to lift water f
