Abstract
The utility model relates to the technical field of a water pump, and specifically to a novel water supply device without negative pressure, which is characterized in that the novel water supply device without negative pressure comprises a water source 1, a water pump 2, a pressure gauge 3, a pneumatic water tank 4, a check valve 5, a gate valve 6, a inflation valve 7, a safety valve 8, a pipeline 9 and a negative pressure regulation device 10, wherein the negative pressure regulation device 10 is arranged under the pneumatic water tank 4; and the negative pressure regulation device 10 is used for outputting energy to the pneumatic water tank 4 to discharge the negative pressure from the pneumatic water tank 4 and the pipeline 9. The novel water supply device without negative pressure provided by the utility model has the advantages that the requirements of water point pressure and water yield and the like are met, and the water cannot be contaminated easily.
Description
Technical field
The utility model relates to the pump technology field, especially a kind of novel non-negative pressure water supply facilities.
Technical background
Automatic water supply equipment generally is made up of three parts, and the water supply capacity of equipment is determined that by water pump assembly the system coordination operation is controlled by switch board.The air pressure energy-storing device comprises barrier film air pressure tank and two kinds of automatic air supply tanks, and its main effect is the energy storage pressurize, deals with a small amount of water supply and normal, leakage, and the while also is the indispensable parts of automatic control.Because the difference of work characteristics, water supply facilities can not arranged the negative pressure in the pipe body sometimes, when malleation is big, just can't regulate pressure, and the energy consumption of water supply facilities is increased greatly.
Summary of the invention
A kind of novel non-negative pressure water supply facilities, it is characterized in that, comprise: water source 1, water pump 2, pressure meter 3, auto-pneumatic cylinder 4, flap valve 5, gate valve 6, charge valve 7, safety valve 8, pipeline 9, negative pressure adjusting device 10, the described negative pressure adjusting device 10 that below air pressure tank body 4, is provided with, described negative pressure adjusting device 10 is to air pressure tank body 4 output energy, get rid of the negative pressure in air pressure tank body 4 and the pipeline 9, when pipeline 9 medium pressure are little, negative pressure adjusting device 10 is started working to air pressure tank body 4 output energy, increase pipeline 9 medium pressure, do not allowed the outer medium of water pump flow backwards or be penetrated in the pipeline 9, satisfy and use water spot hydraulic pressure, requirements such as the water yield, water quality is difficult for contaminated.
The utility model effect is: improve water supply facilities operating efficiency and stability 1.; 2. regulating pressure satisfies with requirements such as water spot hydraulic pressure, the water yields; 3. simple and practical, easy for installation, reduce cost, improved operating efficiency and provided cost savings.
Description of drawings
Fig. 1 is a kind of novel non-negative pressure water supply facilities schematic diagram;
Water source 1, water pump 2, pressure meter 3, auto-pneumatic cylinder 4, flap valve 5, gate valve 6, charge valve 7, safety valve 8, pipeline 9, negative pressure adjusting device 10.
The specific embodiment
Referring to Fig. 1, a kind of novel non-negative pressure water supply facilities, the described negative pressure adjusting device 10 that below air pressure tank body 4, is provided with, described negative pressure adjusting device 10 is to air pressure tank body 4 output energy, get rid of the negative pressure in air pressure tank body 4 and the pipeline 9, when pipeline 9 medium pressure are little, negative pressure adjusting device 10 is started working to air pressure tank body 4 output energy, increase pipeline 9 medium pressure, do not allowed the outer medium of water pump flow backwards or be penetrated in the pipeline 9, satisfy with requirements such as water spot hydraulic pressure, the water yields, water quality is difficult for contaminated.
