Background technology:
The non-negative pressure water-supply installation secondary compression system that is applied to high building more and more widely, non-negative pressure water-supply installation is usually by steady flow compensator, vacuum suppresser, water pump, valve, pipe fitting, sensor, compositions such as electrical control system, its most important function does not have negative pressure function exactly, next is totally-enclosed free of contamination water supply function, though present non-negative pressure water-supply installation can satisfy water supply requirement, but, still have the following disadvantages: first, non-negative pressure water-supply installation is by vacuum suppresser, pressure sensor realizes not having negative pressure function, when the two all breaks down, equipment just might produce negative pressure, and directly has influence on the safety of city planting ductwork.Second, steady flow compensator is an important components, and present non-negative pressure water-supply installation steady flow compensator is made a totally enclosed container usually, and inside does not all have flusher, the inside of accumulating over a long period like this will deposit some incrustation scales and foreign material, and these things can directly influence water supply quality.
Box non-negative pressure method of water supply is that comprehensive traditional secondary booster supplies water and pot type does not have a kind of novel way of supplying water that grows up on the basis of negative pressure relay pressurizing water supply, not enough or accident occurs and cut off the water when causing municipal water supply undesired to solve at municipal ductwork pressure, bring into play its bigger regulating action as a buffer area, water pump changes into from the water intaking pressurization of water tank the inside, because the waterbox design principle is one hour a water supply volume of user around satisfying at least, so can be in the normal normal water supply volume requirement that guarantees the resident of water use peak phase.The anti-negative pressure device of box non-negative pressure water-supply installation is that system realizes the water-supply method conversion and prevents that public pipe network from producing the critical component of no negative pressure, for improving its functional reliability, still needs to update.
The anti-negative pressure measure mode of the box no-negative-pressure water supply equipment that uses is more at present, and is relatively poor aspect operational reliability, the automatic control ability shortcoming of electromechanical integration; And complex structure is made and maintenance, repair cost height.
The utility model content:
The purpose of this utility model is to be used for remedying the anti-negative pressure equipment of the box no-negative-pressure water supply equipment of prior art, and is relatively poor aspect operational reliability, the automatic control ability shortcoming of electromechanical integration; And complex structure is made and the high deficiency of maintenance, repair cost, and is provided more perfect on a kind of structure, guarantees the water system security of operation, and reduces manufacturing, mounting cost greatly, makes the simpler and more direct anti-negative pressure device of maintenance, repair.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of anti-negative pressure device that is used on the box no-negative-pressure water supply equipment, this device is made up of feed pipe, urceolus, flange, electromagnetic valve and sensor, and described electromagnetic valve directly is connected with feed pipe with sensor; Described electromagnetic valve is arranged on the upper end of three-dimensional feed pipe;
Described sensor is arranged on the feed pipe water inlet end;
Described urceolus is inserted in the urceolus lower cover to the urceolus loam cake by the feed pipe water side, and back, urceolus location is fixed by compact heap;
Described feed pipe water inlet end and water side are respectively arranged with water-in flange and water-output flange;
Described electromagnetic valve is for adopting normally open solenoid valve, and sensor is a pressure sensor;
The water-in flange of described water inlet end is a loose flange.
The anti-negative pressure device that the utility model is used for box no-negative-pressure water supply equipment has solved device systems and has cut off the water or fetch water switching during the water supply flow wretched insufficiency at the public pipe network of tap water, guarantee the public pipe network of tap water not to be produced the negative pressure suction, and make every effort to simple in structure, maintenance, repair are convenient, perfect in shape and function, with high content of technology, reliable, Operation and Maintenance, maintenance have good social benefit easily.Compact conformation of the present invention is reasonable, and assembling and setting is simple, reduces manufacturing cost, has good business economic benefit.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation
Fig. 2 is that A among Fig. 1 is to figure
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to shown in Figure 1: a kind of anti-negative pressure device that is used on the box no-negative-pressure water supply equipment, this install by feed pipe 10,11, and 12, urceolus 5, flange 1,3,8, electromagnetic valve 4 and sensor 6 compositions, electromagnetic valve 4 directly is connected with feed pipe 12 with sensor 6; Electromagnetic valve 4 is arranged on the upper end of three-dimensional feed pipe 12 by fastening devices, electromagnetic valve 4 supplies water to city planting ductwork by auto-closing, the pressure sensor 6 that is used for conducted signal is arranged on feed pipe water inlet end 10, little when the city planting ductwork water supply flow, when pressure drops to setting value, pressure sensor 6 carries out the transmission of signal; Urceolus 5 is inserted in urceolus lower cover 2 to urceolus loam cake 7 by feed pipe water side 11; and back, urceolus 5 location is fixing by compact heap 9; as shown in Figure 2; can protect inner electromagnetic valve 4 and the pressure sensor 6 that is provided with by urceolus 5; be respectively arranged with water-in flange 8 and water-output flange 1 at feed pipe water inlet end 10 and water side 11; three-dimensional feed pipe 12 and water inlet end 10 and water side 10 interconnect by flange 3,8.
Normally open solenoid valve 4 is in normally open when city planting ductwork normal water supply flow,, pressure little when the city planting ductwork water supply flow drops to setting value, pressure sensor 6 transmits signal to control system, make electromagnetic valve 4 auto-closings disconnect city planting ductwork and supply water, water pump changes water intaking forced feed user in the water tank into; After city planting ductwork supplied water recovery normally, pressure sensor 6 transmitted signals to control system, made electromagnetic valve 4 unlatching and disconnection cistern water supply automatically, directly supplied with the user from city planting ductwork water intaking relay pressurizing.Equipment microcomputer in running is monitored city planting ductwork and system pressure constantly, automatically control vacuum suppresser and steady flow compensator suppress the generation of negative pressure, both made full use of the pressure of city planting ductwork, do not produce negative pressure again, city planting ductwork is not produced any harmful effect, guaranteed the safety of water.Non-negative pressure water-supply installation can utilize original pressure of tap water pipe network, can employ enough storage water yields again and satisfy the peak period water, and can not produce suction to the tap water pipe network.
