Abstract
The invention provides a non-negative pressure water supply device not only implementing non-negative pressure, but also conveniently implementing flow stabilizing compensator inner washing. According to the invention, a negative pressure automatic isolator is installed on the water inlet pipe of the water supply device. When negative pressure is generated in the flow stabilizing compensator and can not be eliminated, the negative pressure automatic isolator automatically cut the connection between the device and the urban water supply pipe, so as to protect safety of the urban water supply pipe; meanwhile, a branch conduit is led from the water outlet of the water pump into the internal for the flow stabilizing compensator, thus internal washing of the flow stabilizing compensator is convenient.
Description
Technical field
A kind of non-negative pressure water-supply installation that is applied to the high building pressurization belongs to the non-negative pressure water-supply installation field.
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.
Summary of the invention
Goal of the invention of the present invention be to provide a kind of can the above defective of customer service, can reliably realize not having negative pressure, can conveniently realize the non-negative pressure water-supply installation of steady flow compensator interior flushing again.
Goal of the invention of the present invention is achieved in that the present invention installs an automatic isolator of negative pressure on the water inlet pipe of supply equipment, in the time of can not eliminating when producing negative pressure in the steady flow compensator, the automatic isolator of negative pressure disconnects equipment and municipal network water supply automatically, thus the safety of protection city planting ductwork; Simultaneously, pick out an arm at the delivery port of water pump and be incorporated into steady flow compensator inside, can wash steady flow compensator inside easily, thereby realize purpose of the present invention.
The present invention has improved the reliability and the safety of supply equipment widely, has guaranteed the water quality that supplies water.

The specific embodiment
Below with reference to above accompanying drawing, the specific embodiment of the present invention is done further detailed description.
The automatic isolator of negative pressure (1) is installed between city planting ductwork (2) and the equipment water inlet pipe (4), equipment water inlet pipe (4) is connected with steady flow compensator (3), and the delivery port of equipment water inlet pipe (4) is positioned at the inner top of steady flow compensator (3), vacuum suppresser base (5) and pressure sensor (7) are arranged on steady flow compensator (3), vacuum suppresser (6) is installed on vacuum suppresser base (5), blowoff valve (10) and pump water inlet (8) are housed in the bottom of steady flow compensator (3), pump water inlet (8) is connected with the water inlet of water pump (9), delivery port at water pump (9) connects pumping line (11), main gate valve (12) is installed on pumping line (11), on the pumping line (11) between water pump (9) and the main gate valve (12), be connected to cleaning hose (14), cleaning hose (14) can be incorporated into water in the inner chamber of steady flow compensator (3) from pumping line (11), and flushing gate valve (13) is housed on cleaning hose (14).The automatic isolator of negative pressure (1), pressure sensor (7) and water pump (9) all are connected with electrical control cabinet by lead.
During operate as normal, flushing gate valve (13) is in closed condition, water from city planting ductwork (2) through the automatic isolator of negative pressure (1) access arrangement water inlet pipe (4), enter then in the inner chamber of steady flow compensator (3), water pump (9) is transported to pumping line (11) after water is pressurizeed by pump water inlet (8), is fed to the user by main gate valve (12).When coming the water yield less than water supply volume, liquid level descends in the steady flow compensator (3), realizes not having negative pressure function by vacuum suppresser (6) and pressure sensor (7) before producing negative pressure.
After vacuum TVS (6) and pressure sensor (7) all produce fault; steady flow compensator will produce negative pressure in (3); when negative pressure involves the automatic isolator of negative pressure (1); the automatic isolator of negative pressure (1) will be closed by atmospheric effect; city planting ductwork (2) and equipment water inlet pipe (4) are cut off; thereby avoid negative pressure that city planting ductwork (2) is impacted; the automatic isolator of negative pressure (1) will send alarm signal to electrical control cabinet simultaneously; stop the running of water pump (9), equipment is played a protective role.
When needs carry out steady flow compensator (3) interior flushing, close main gate valve (12), open flushing gate valve (13), this moment, water will form a circulation, the water of elevated pressures sprays to the bottom of steady flow compensator (3) from cleaning hose (14), thereby incrustation scale and dirt are dashed, open blowoff valve (10) this moment and will easier incrustation scale and dirt be discharged, so just realized purpose of the present invention.When practical operation, can utilize blowoff valve (10) to adjust water level in the steady flow compensator (3), thereby obtain developing result preferably.
Institute it should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should contain and covers in the middle of claim scope of the present invention.
