One works, no negative pressure controller no negative flow controller uses patented technology (patent number: 9205.1) time monitoring and control of municipal pipe network and Compensation tank pressure, when there is insufficient water pressure, no negative pressure controller begins work to ensure that pressure is not affected municipal pipe network, water companies, No. 135 document provides municipal pressure can not be less than 2KG, no negative flow controller not only to ensure the security and stability of water users, while ensuring the stability of the municipal pipe network pressure . Two, two-way compensation device uses patent technology of energy storage and release of a two-way compensation adjustment device (patent number: ZL9417.8) water pipe network can automatically compensate for continuous water, can also play a role in the user network regulator compensation ensure that the equipment on the water pipe network does not produce negative pressure water low peak-way compensator work, the end of high-pressure water pump outlet toward the low pressure chamber, to pay the low pressure chamber, fill up after a low pressure chamber, close, high-pressure chamber to continue to pay again when level gradually increased, with the weight of the inert gas is squeezed back energy storage in the device, thus completing the process of low peak to the tank water, when the peak of water or municipal pipe network pressure drop, Changsha, China Zhen Pump Limited two-way device to compensate for constant water chamber, while the energy storage device to release the energy of water, low-pressure chamber, the plot squeeze water pressure chamber to the low pressure chamber water, sinks with constant pressure chamber together with the municipal water supply water to the water, thus completing the peak of the user replenishment process. Third, the energy storage technology using patented energy storage (patent number: 9204.7) with built-in pressure does not float on water, inert gas, when the peak of the water, releasing energy squeeze water pressure chamber to the low pay, take advantage of energy conservation principles of law to achieve the peak of water to the user to ensure that the water in the tank to the greatest degree of compensation to the user's network, the inhibition of negative pressure to produce, to assure municipal pipe network impact. Energy-saving features of the traditional way of water supply reservoir can not be separated, the water reservoir is generally supplied by the water pipe network, so that the original pressure of the water into the pool becomes a zero pressure, and then began to pressure from zero pressure , resulting in substantial waste of power resources. Tank pressure laminated secondary pressurized water supply equipment, is an ideal energy-saving water supply equipment, it is a direct connection with the water pipe network, water pipe network does not produce any side effects of secondary water supply equipment, municipal directly overlying pressure on the basis of water supply pipe network, energy conservation, and also has a fully enclosed, non-polluting, small footprint volume, quick installation, reliable operation, easy maintenance and many other advantages. Tank pump integrated equipment works secondary pressurized water supply equipment into the water pressure and water pipe network is directly connected to the remaining water in the water pipe network pressure-driven equipment pushed into the water, the water pressure pump equipment residual pressure Based on the continued pressure will increase water pressure to the pressure required by the user after the outlet pipe network water; specifically: When users tap water supply pipe network is greater than the amount of inlet pressure drops, Changsha, vibration pump Co. intake pressure drops when the device is less than zero absolute pressure (or pressure pipe network protection setting), the device of the negative pressure to prevent and control the device automatically starts to work on the equipment running until adjusted standby equipment downtime, Make sure no water pipe network pressure and reduce adverse impacts on the water pipe network; when the ability to restore the water supply pipe network, network pressure inlet pressure recovery to protect the above, the device automatically starts to restore normal supply; when the water pipe network the remaining water pressure to meet user requirements, the device automatically enters sleep mode, the water directly to the user by the water pipe network, lack of water supply equipment to automatically resume operation; when the user does not use water or water is very small, the device automatically enters sleep mode shutdown by setting In the small flow regulator packing equipment water tank side to maintain the number of users of water leaking pipe network, users of water tank holding pressure regulator can not maintain the desired pressure of the water supply network, the device automatically wake up and resume normal operation. Process equipment running full use of the remaining pressure water pipe network, not always adversely affect the water pipe network also satisfy customer needs, reduce water consumption and achieve optimal operation of water supply systems.
