Abstract
本实用新型涉及水泵技术领域，尤其一种新型无负压给水设备，其特征在于，包括：管道、水泵、压力表、控制装置、止回阀、闸阀、控制阀、安全阀、第一控制阀、第二控制阀，所述一种新型无负压给水设备，在管道中设有第二控制阀，所述第二控制阀是向管道启动输出气体能量，调节水源管道中的水压，当管道中水压力小的时候，输出保压气体能量，调节水源管道介质压力，满足用水点水压、水量要求，简单实用，安装方便，降低成本。
The utility model relates to the technical field of water pumps, in particular to a new type of non-negative pressure water supply equipment, which is characterized in that it includes: pipelines, water pumps, pressure gauges, control devices, check valves, gate valves, control valves, safety valves, and first control valves. . The second control valve, the new type of non-negative pressure water supply equipment, is provided with a second control valve in the pipeline, and the second control valve is to start and output gas energy to the pipeline to adjust the water pressure in the water source pipeline. When the water pressure in the pipeline is low, the energy of the pressure-holding gas is output to adjust the medium pressure of the water source pipeline to meet the water pressure and water volume requirements of the water point. It is simple and practical, easy to install, and reduces costs.
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.
