Abstract
The utility model relates to a kind of non-negative pressure water-supply installation with automatic decompression device, comprise steady flow compensator, valve, water pump, pressure sensor, pressure meter, base, each water pump is all directly connected on by steady flow compensator on the waterline network of municipal tap water company, each water pump is equipped with corresponding valve, it is online that pressure sensor and pressure meter are installed on outlet pipe, and the bypass pipe that described steady flow compensator is communicated with water outlet pipe network is provided with automatic decompression device.By such improvement, whole water supply network is well protected, when after pump, pressure is increased to certain value, automatic decompression device will be opened automatically, and pressure is down to normal pressure limit automatically, the normal water supply simultaneously do not affected.
Description
Technical field
The utility model relates to non-negative pressure water-supply installation technical field, especially a kind of non-negative pressure water-supply installation with automatic decompression device.
Background technology
Non-negative pressure water-supply installation is applied in the secondary pressurized system of municipal water supplies, high building water more and more widely, this equipment has steady flow compensator, negative pressure inhibition device, water pump, valve, pipe fitting, sensor, electrical control system usually, its most important function is normal water supply while, ensure that steady flow compensator does not form a negative pressure state, is secondly totally-enclosed pollution-free.Its basic functional principle is: it is directly connected on by steady flow compensator on the waterline network of municipal tap water company by water pump, the water of tap water pipe network directly enters regulating tank, when the pressure of tap water pipe network can not meet require with water time, the online pressure sensor of outlet pipe is sampled to hydraulic pressure, pressure signal is changed the corresponding signal of telecommunication, feeding frequency converter or intelligent controller compare calculation through the force value that conversion is given with user, result is changed into the frequency adjusting signals controlling frequency converter out-put supply frequency, export control pump start stop signal simultaneously, by regulating running pumping source frequency, make the stable water pressure of user's pipe network in pre-set force value.
Although current non-negative pressure water-supply installation can meet water supply requirement, but analyze according to the actual service condition in scene, also have the following disadvantages: when the pressure sensor that outlet pipe is online occurs abnormal, frequency converter or controller do not receive pressure signal, take for pressure and can not meet instructions for use always, and then heighten the running frequency of pump motor always, water supply network pressure constantly increases, when being increased to certain value, cause water supply network to break, say and cause very large economic loss and negative effect.
Utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of non-negative pressure water-supply installation with automatic decompression device.
The utility model solves the technical scheme that its technical problem adopts: a kind of non-negative pressure water-supply installation with automatic decompression device, comprise steady flow compensator, valve, water pump, pressure sensor, pressure meter, base, each water pump is all directly connected on by steady flow compensator on the waterline network of municipal tap water company, each water pump is equipped with corresponding valve, it is online that pressure sensor and pressure meter are installed on outlet pipe, and the bypass pipe that described steady flow compensator is communicated with water outlet pipe network is provided with automatic decompression device.
The beneficial effects of the utility model are, by such improvement, whole water supply network are well protected; when after pump, pressure is increased to certain value; automatic decompression device will be opened automatically, and pressure is down to normal pressure limit automatically, the normal water supply simultaneously do not affected.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure 1, steady flow compensator, 2, valve, 3, water pump, 4, pressure sensor, 5, pressure meter, 6, automatic decompression device, 7, base.
Detailed description of the invention
If Fig. 1 is an example structure schematic diagram of the present utility model, it comprises; Steady flow compensator 1, valve 2, water pump 3, pressure sensor 4, pressure meter 5, automatic decompression device 6, base 7.With base 7 for outside framework, inside be provided with two groups of water service pipes, water service pipe is equipped with water pump 3, valve 2 is equipped with before and after on each water pump 3, two water service pipes are communicated with the outlet pipe of base 7 bottom, outlet pipe is established pressure sensor 4 and pressure meter 5, outlet pipe separately establishes bypass line, bypass pipe is established automatic decompression device 6.
When system normal water supply, automatic decompression device 6 is in closed condition.When pressure sensor on outlet pipe 4 occurs abnormal, ductwork pressure will be caused constantly to rise, when rising to certain value, automatic decompression device 6 will be opened, by excess pressure Self-tipping in steady flow compensator 1, in order to avoid outlet pipe damages because pressure constantly rises.
