Abstract
The utility model relates to a variable frequency jet accumulation adjusting type pressure water supply device, which comprises an auxiliary accumulation adjusting water tank, a water pump, an electric control system, a jet device, a pressure sensor, a pipe valve and the like. One branch of a municipal water feeding pipe is connected with the inlet of the jet device, and one branch of the municipal water feeding pipe enters the water tank. When the pressure water supply device operates normally and the municipal water flows through the jet device, vacuum can be generated in the absorption chamber part due to the special structure of the jet device so as to absorb water in the water tank, and the water flows into the inlet of the water pump after being mixed in the mixing chamber to form pressurized water, and is then supplied to the user after being pressurized. The combination of the jet device and the auxiliary accumulation adjusting water tank eliminates the impact of the negative pressure on the water inlet, thereby realizing the direct serial connection with the municipal pipe network and the utilization of the original pressure of the municipal water. Moreover, part of spare water can be stored in the auxiliary accumulation adjusting water tank so as to adjust the water supply during peak periods when the municipal water is not sufficient or is cut off.
Description
1, technical field
The utility model relates to a kind of water supply facilities, and specifically a kind of frequency conversion jet holds accent type pressurizing feedwater equipment.
2, background technology
At present, in secondary pressurizing feedwater field, the most frequently used pressurizing feedwater mode has: high level cistern feedwater, pneumatic water supply, frequency conversion feedwater and the modes such as non-negative pressure water supply of newly rising and being promoted rapidly in recent years, and high level cistern feedwater, pneumatic water supply, frequency conversion water supply modes are because of all being provided with bigger water storage box, make secondary pollution comparatively serious, and municipal water puts into water tank secondary pressurization more entirely, wastes original municipal tap water pressure.No-negative-pressure water supply equipment directly is concatenated into the city planting ductwork pressurizing feedwater, and overcome secondary pollution and the problem that wastes energy, but do not had the shortcoming that also there is a maximum in negative pressure equipment, be exactly not lay in water, in case cut off the water or the tap water quantity not sufficient will cause and cuts off the water.This makes no-negative-pressure water supply equipment be subjected to bigger restriction in the application in some areas that often cut off the water.
In order to solve this type of problem, method commonly used now is, adopt the water supply modes of no negative pressure equipment use in parallel with water tank, promptly at a no negative pressure equipment water inlet water storage box in parallel, the standby water of storage compartment, with solution cut off the water or during the water of peak city planting ductwork come hydropenic phenomenon, but have the switching problem of no negative pressure and water tank, control is complicated, and there is hidden danger in reliability.
3, utility model content
The purpose of this utility model is the technical problem that exists at existing secondary pressurizing feedwater mode, provides a kind of frequency conversion jet that is used for the secondary pressurization to hold accent type pressurizing feedwater equipment.This equipment can directly be concatenated into pressurizing feedwater on the city planting ductwork, and the parallel connection of equipment water inlet the one auxiliary water transfer case that holds, mix again through the water supply of water pump pressurization rear line by an ejector with water tank water the municipal tap water, because the design feature of ejector itself makes this equipment can utilize original municipal pressure, realize energy-conservationly, and be provided with and hold the water transfer case, laid in the standby water of part, be particularly suitable for the area of some city planting ductwork imperfections or peak period output deficiency
The purpose of this utility model is achieved through the following technical solutions:
A kind of frequency conversion jet holds accent type pressurizing feedwater equipment, held water transfer case, water pump, electric-control system, ejector, pressure sensor, pipe fitting valve etc. and formed by auxiliary, municipal water inlet pipe one tunnel is directly received the ejector import, and one the tunnel enters water tank, during the equipment operate as normal, when municipal administration water passes through ejector, because the special construction of ejector produces vacuum at the suction chamber position, water tank water is sucked, after mixing chamber is mixed into pressure water, enter pump entrance, after pressurization, be fed to the user.The ejector of equipment holds the synergy of water transfer case with auxiliary, the negative pressure influence of abatement apparatus water inlet, realized directly being connected in series with city planting ductwork, utilize municipal original pressure, and be provided with and auxiliary hold the water transfer case and laid in the standby water of part, municipal administration water shortage or the water when cutting off the water in the time of can regulating the peak.
The beneficial effects of the utility model are, the water supply facilities water inlet directly links to each other with city planting ductwork on the one hand and is connected to the auxiliary water transfer case that holds on the other hand, add by fluidic device and water pump and to press to the user and supply water, equipment directly is connected in series with city planting ductwork, utilize municipal original pressure to realize energy-conservation, and auxiliary hold the water transfer case and have certain water storage function, municipal administration water shortage or the emergent water when cutting off the water in the time of can regulating the peak.
4, description of drawings
Accompanying drawing 1 is a structure diagram of the present utility model.
Among the figure, 1, municipal water inlet pipe, 2, water pump, 3, the auxiliary water transfer case that holds, 4, fluid level controller, 5, electric-control system, 6, the delivery port pressure sensor, 7, ejector, 8, the water inlet pressure sensor, 9, motor operated valve, 10 one way valves, 11, user's pipe network.
5, the specific embodiment
As shown in drawings, a kind of frequency conversion jet of the utility model holds accent type pressurizing feedwater equipment, be by water pump (2), the auxiliary water transfer case (3) that holds, fluid level controller (4), electric-control system (5), delivery port pressure sensor (6), ejector (7), water inlet pressure sensor (8), motor operated valve (9), one way valve (10) is formed, municipal administration water inlet pipe (1) a tunnel is directly received ejector (7) import, one the tunnel enters the auxiliary water transfer case (3) that holds, after ejector (7) two path water mixes, enter water pump (2) inlet, under electric-control system (5) is controlled by the pressure that detects mouth of a river pressure sensor (6), realize constant pressure water supply, equipment also can be realized the mixing ratio of two path water by control motor operated valve (9), can avoid the situation of water tank aqueous metamorphism.Because of equipment importation directly is connected in series city planting ductwork, can utilize original pressure, realize energy-conservationly, and auxiliary hold the water transfer case and have certain water storage function, municipal administration water shortage or the emergent water when cutting off the water in the time of can regulating the peak.
Institute it should be noted that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, the technical solution of the utility model is made amendment or is equal to replacement, and do not break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
