Abstract
The utility model relates to the technical field of water pump, and particularly to novel no-negative-pressure water supply equipment. The novel no-negative-pressure water supply equipment is characterized in that: the novel no-negative-pressure water supply equipment comprises pipeline, a water pump, a pressure gauge, a control device, a check valve, a gate valve, a control valve, a safety valve, a first control valve and a second control valve; the pipeline is internally provided with the second control valve which starts air energy output to the pipeline and adjusts the water pressure in water source pipeline; and when the water pressure in the pipeline is small, pressure holding air energy is output for adjusting medium pressure of the water source pipeline and satisfying the requirement for water pressure and water amount at the water using point. The novel no-negative-pressure water supply equipment has the following advantages: simple structure, high practicability, high convenience in mounting, and reduced cost.
Description
Technical field
The utility model relates to the pump technology field, especially a kind of novel non-negative pressure water supply facilities.
Background technology
Automatic water supply equipment generally is comprised of three parts, and the water supply capacity of equipment determines by water pump assembly, and the coordinated operation of equipment is controlled by switch board.The air pressure energy-storing device comprises two kinds of diaphragm air pressure tank and automatic makeup gas tanks, and its Main Function is the energy storage pressurize, deal with a small amount of water supply and normal, reveal, also be simultaneously automatic indispensable parts of control.Because the difference of work characteristics, the pipe body pressure transient uses water spot hydraulic pressure unstable sometimes, also easily brings water pollution simultaneously.
Summary of the invention
For overcoming the above problems, the utility model provides a kind of novel non-negative pressure water supply facilities, it is characterized in that, comprise: pipeline 1, water pump 2, pressure meter 3, control device 4, flap valve 5, gate valve 6, control valve 7, safety valve 8, the first control valve 9, the second control valve 10, described a kind of novel non-negative pressure water supply facilities, in pipeline 1, be provided with the second control valve 10, described the second control valve 10 is to start the output gas energy to pipeline 1, regulate the hydraulic pressure in the water pipeline 1, when water pressure is little in the pipeline 1, output pressurize gas energy is regulated water pipeline 1 pressure medium, satisfies and uses water spot hydraulic pressure, water yield requirement.
Effect of the present utility model is: improve water supply facilities operating efficiency and stability 1.; 2. regulating pressure satisfies with water spot hydraulic pressure, water yield requirement; 3. simple and practical, easy for installation, reduce cost.
Description of drawings
Fig. 1 is the utility model schematic diagram;
Wherein: pipeline 1, water pump 2, pressure meter 3, control device 4, flap valve 5, gate valve 6, control valve 7, safety valve 8, the first control valve 9, the second control valve 10.
The specific embodiment
Referring to Fig. 1, described a kind of novel non-negative pressure water supply facilities, in pipeline 1, be provided with the second control valve 10, described the second control valve 10 is to start the output gas energy to pipeline 1, regulate the hydraulic pressure in the water pipeline 1, when water pressure is little in the pipeline 1, output pressurize gas energy, regulate water pipeline 1 pressure medium, satisfy with water spot hydraulic pressure, water yield requirement.
