Abstract
The utility model belongs to the field of boosting water supply devices, and particularly relates to a negative pressure free pipe network pressure folding water supply device. Chinese water supply modes at present comprise high position water tank water supply, air pressure water supply, frequency conversion speed adjustment power supply and the like, the power supply modes can firstly store water in a water pool or a water tank, and then give pressure to supply water under the condition that water supply pipe network pressure is not enough, thereby wasting original water pressure of the water supply pipe network greatly, enabling the water pressure to generate secondary pollution, and being unbeneficial for constructing saving type society. The negative pressure free pipe network pressure folding power supply device comprises a negative pressure preventing device, a flow stabilizing tank, a pressure sensor, a water pump machine set, a bypass pipe and an automatic control cabinet, wherein the top portion of the negative pressure preventing device is provided with a liquid level detector, an air feeding pipe, a floating ball and an air leakage hole. The power supply device can suck water directly from the water feeding pipe, and can not generate any influence on other users of the water feeding pipe, and the power supply device realized pressure folding power supply of the pipe network.
Description
Technical field
The utility model belongs to pressurization supply equipment field, and particularly a kind of negative pressure-free pipe network Pressure-superposed water supply equipment can directly absorb water from waterline network, and come control of pump (group) frequency control constant-pressure operation according to the difference of customer requirements pressure and grid pressure.
Technical background
Present stage, China's way of supplying water had high-level tank water, pressure water supply, frequency modulation water supply etc.These way of supplying water are under the situation of waterline network insufficient pressure, earlier water is stored in pond or the water tank, carry out pressurizing feedwater again, this has just wasted the original hydraulic pressure of waterline network, also makes hydraulic pressure produce secondary pollution, and is very unfavorable to building a conservation-minded society, utilize problem at the original hydraulic pressure of waterline network, developed a kind of can directly the suction, can not produce the supply equipment of any influence, realized pipe network pressure-superposed water supply other users of waterline network from waterline network.
Summary of the invention
The purpose of this utility model provides a kind of negative pressure-free pipe network Pressure-superposed water supply equipment, solved force (forcing) pump can not be directly from waterline network suction problem, make that laminating supplies water is applied.
The technical scheme that the utility model adopted is:
A kind of negative pressure-free pipe network Pressure-superposed water supply equipment comprises anti-negative pressure device, the current stabilization jar, first pressure sensor, second pressure sensor, water pump assembly, bypass pipe, automatic control cabinet, it is characterized in that level sensor, ventilating pipe, ball float, deflation hole being installed at the top of anti-negative pressure device, described level sensor links to each other with automatic control cabinet, described first pressure sensor and second pressure sensor are connected the import and export of automatic control cabinet and water pump assembly, on the pipeline between described water inlet and the delivery port bypass pipe are installed.
Described ventilating pipe stretches into anti-negative pressure device bottom.
The beneficial effects of the utility model are: the pipe network pressure-superposed way of supplying water following advantage of having compared with alternate manner:
(1) because waterline network directly absorbs water, can save and build pond or water tank spending.
(2) because waterline network directly absorbs water, avoided water to contact, prevented water pollution once again with atmosphere.
Description of drawings
Fig. 1 is anti-negative pressure device schematic diagram;
Fig. 2 is a pipe network negative pressure water supply schematic diagram.
Above-mentioned number in the figure explanation: 1-prevents negative pressure device, 2-current stabilization jar, 3-first pressure sensor, 4-second pressure sensor, 5-water pump assembly, 6-bypass pipe, 7-automatic control cabinet, 8-level sensor, 9-ventilating pipe, 10-ball float, 11-deflation hole.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, Fig. 2:
A kind of negative pressure-free pipe network Pressure-superposed water supply equipment comprises anti-negative pressure device 1, current stabilization jar 2, first pressure sensor 3, second pressure sensor 4, water pump assembly 5, bypass pipe 6, automatic control cabinet 7, top at anti-negative pressure device 1 is equipped with level sensor 8, ventilating pipe 9, ball float 10, deflation hole 11, ventilating pipe 9 stretches into anti-negative pressure device bottom, level sensor 8 links to each other with automatic control cabinet 7, and first pressure sensor 3 and second pressure sensor 4 are connected the import and export of automatic control cabinet 7 and water pump assembly 5, and bypass pipe 6 is installed on the pipeline between water inlet and the delivery port.
Referring to Fig. 1:
The utility model is anti-negative pressure device, is cylinder.
Anti-negative pressure device has following function;
(1) initial operating stage degassing function;
(2) when the waterline network pressure oscillation, cause liquid level change, actual liquid level is passed to automatic control cabinet.
Referring to Fig. 2:
Steady flow compensator and anti-negative pressure device are one group of gas, when system's initial operating stage moisturizing, gas is run out of from the deflation hole in the equipment, when liquid level rises, makes ball float close the deflation hole, upper space just is full of air, air carries out compressing and expanding under the effect of waterline network feed pressure, the pressure that different liquid levels is corresponding different so just can be provided with peak level and lowest water level, water level is higher than peak level explanation waterline network pressure and satisfies the requirement of user's hydraulic pressure, and water pump quits work; Water level is lower than lowest water level explanation waterline network pressure and is lower than the pneumatics power of establishing, and water pump continues operation will produce draft to pipe network, influences the stability of pipe network, so the termination of pumping instruction takes place.
