Abstract
The utility model discloses a kind of city high-rise residential building tap water non-negative pressure stable-pressure device, comprise tap water pipe network outlet pipe, pressurized pump station water inlet pipe, pressurized pump station, pressurized pump station outlet pipe, vacuum tank and barrier film capsule, tap water pipe network outlet pipe is connected with pressurized pump station water inlet pipe; Pressurized pump station outlet pipe is connected with building user's water supply pipe; In vacuum tank, be provided with at least one telescopic barrier film capsule; The inner chamber of barrier film capsule communicates with the outlet pipe of pressurized pump station; Between barrier film capsule outer walls and vacuum tank inwall, be gas chamber, be filled with nitrogen in chamber, nitrogen pressure equates with the required pressure of supply water that meets building tap water; The inflation inlet of nitrogen chamber is arranged on the sidewall of vacuum tank.When the tap water pressure in barrier film capsule changes, barrier film capsule is dilatation thereupon, can compensate in time tap water pressure poor; Because the water in barrier film capsule does not contact with the nitrogen in vacuum tank, so nitrogen do not run off, and plays the stable effect of pressure compensation.
Description
Technical field
The utility model relates to a kind of without negative pressure stable-pressure device, relates in particular to the tap water non-negative pressure stable-pressure device of a kind of city high-rise residential building, belongs to supply equipment technical field.
Background technology
The end of municipal network water supply, conventionally by the tap water of 3kgf/cm2 pressure roughly, offers the pressurized pump station of a plurality of high-rise residential buildings, and pressurized pump station flows to building user by the tap water after supercharging again.The tap water pressure providing due to municipal network water supply often fluctuates greatly, when each end of pipe network is during simultaneously in opening, its pressure of supply water can produce the sudden change that declines, and therefore, the pressure of supply water of pressurized pump station output also can fluctuate because of the running water pressure fluctuation of municipal network water supply.The way that prior art addresses this problem is: the inlet pipes that is pressurized pump station at the end of municipal network water supply arranges a vacuum tank, vacuum tank top installation one is filled with the air bag of fixed volume nitrogen, air pressure is generally about 3 standard atmospheric pressures of 3kgf/cm2(), when the tap water of 3kgf/cm2 pressure enters in tank, the gentle bag pressure dynamic balance of tap water, does not act on mutually; When tap water pressure is less than gasbag pressure, air bag, to liberating nitrogen atmospheric pressure in tank, makes tap water boosting arrive 3kgf/cm2, thereby realizes the substantially invariable object of import hydraulic pressure of pressurized pump station.This voltage regulation way is the direct acquisition that contacts and interact with water by nitrogen, wherein a part of nitrogen molecule can enter in water, and by water, taken away under the effect of pumping plant, nitrogen volume in original air bag is reduced, cause the not enough 3kgf/m2 of actual pressure in air bag, do not have pressure compensation effect, make still to produce in user pipe certain negative pressure.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of city high-rise residential building tap water non-negative pressure stable-pressure device, flows to the outlet pipe of building for being arranged on pressurized pump station, guarantees in user pipe without negative pressure.
To achieve these goals, the utility model adopts following technical scheme: a kind of city high-rise residential building tap water non-negative pressure stable-pressure device, comprise tap water pipe network outlet pipe, pressurized pump station water inlet pipe, pressurized pump station, pressurized pump station outlet pipe, vacuum tank and barrier film capsule, tap water pipe network outlet pipe is connected with pressurized pump station water inlet pipe; Pressurized pump station outlet pipe is connected with building user's water supply pipe; In vacuum tank, be provided with at least one telescopic barrier film capsule; The inner chamber of barrier film capsule communicates with the outlet pipe of pressurized pump station; Between barrier film capsule outer walls and vacuum tank inwall, be gas chamber, be filled with nitrogen in chamber, nitrogen pressure equates with the required pressure of supply water that meets building tap water; The inflation inlet of nitrogen chamber is arranged on the sidewall of vacuum tank.
In the gas chamber of the utility model between vacuum tank inwall and barrier film capsule outer walls, be full of the nitrogen of setting pressure, and the inner chamber of barrier film capsule and the outlet pipe of pressurized pump station are communicated, when the tap water pressure in barrier film capsule changes, due to barrier film capsule dilatation at any time, thereby the tap water pressure in compensation booster pumping plant outlet pipe is poor in time, guarantees in user pipe without negative pressure; Because the water in barrier film capsule does not contact with the nitrogen in vacuum tank, thereby nitrogen can not run off, and plays the stable effect of pressure compensation.
As further improvement of the utility model, above-mentioned barrier film capsule is two.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks, broken section structural representation.
Wherein: 1 tap water pipe network outlet pipe, 2 pressurized pump station water inlet pipes, 3 pressurized pump stations, 4 vacuum tanks, 5 and 5 ' barrier film capsule, 6 pressurized pump station outlet pipes, A inflation inlet.
The specific embodiment
Take barrier film capsule as two be example by reference to the accompanying drawings specific embodiment of the present utility model being described further.
As shown in Figure 1, tap water pipe network outlet pipe 1 is connected with pressurized pump station water inlet pipe 2; Pressurized pump station outlet pipe 6 is connected with building user's water supply pipe; In vacuum tank 4, be provided with two telescopic barrier film capsules 5 and 5 '; Barrier film capsule 5 and 5 ' inner chamber communicate with pressurized pump station outlet pipe 6; Between barrier film capsule 5 and 5 ' outer wall and the inwall of vacuum tank 4, be gas chamber, be filled with nitrogen in chamber, nitrogen pressure equates with the required pressure of supply water that meets building tap water; The inflation inlet A of gas chamber is arranged on the sidewall of vacuum tank 4.
The present embodiment arranges two barrier film capsules 5 and 5 ' vacuum tank 4 is interior, and in the gas chamber between vacuum tank 4 inwalls and two barrier film capsules 5 and 5 ' outer wall, be full of the nitrogen of setting pressure, make the inner chamber of barrier film capsule 5 and 5 ' communicate with pressurized pump station outlet pipe 6 simultaneously, when the tap water pressure in barrier film capsule 5 and 5 ' changes, barrier film capsule 5 and 5 ' is dilatation thereupon, thereby the tap water pressure in compensation booster pumping plant outlet pipe 6 is poor in time, guarantees in user pipe without negative pressure; Because barrier film capsule 5 does not contact with the nitrogen in vacuum tank 4 with the water in 5 ', thereby nitrogen can not run off, and plays the stable effect of pressure compensation.
