Abstract
The utility model discloses a kind of city tap-water pipe network end without negative pressure stable-pressure device, comprise tap water pipe network outlet pipe, vacuum tank, barrier film capsule and pressurized pump station, the inwall of vacuum tank is the cavity that holds aqueous water; In vacuum tank, be provided with at least one telescopic barrier film capsule, this barrier film capsule outer walls contacts with aqueous water, is filled with at least nitrogen of 3kgf/m2 in barrier film capsule, and the inflation inlet of barrier film capsule is fixed on the sidewall of vacuum tank; The water inlet of vacuum tank is connected with the outlet pipe of city planting ductwork, and the delivery port of vacuum tank is connected with the water inlet of pressurized pump station.The utility model arranges barrier film capsule in vacuum tank, the nitrogen in barrier film capsule is not contacted with the water in vacuum tank, thereby nitrogen can not run off; Simultaneously in the time that the fluid pressure in tank changes, due to barrier film capsule dilatation at any time, thereby the pressure differential in compensating tank in time, ensure in user pipe without negative pressure.
Description
Technical field
The utility model relates to a kind of without negative pressure stable-pressure device, relate in particular to a kind of city tap-water pipe network end without negative pressure stable-pressure device, belong 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 multiple communities and building, and pressurized pump station flows to user by the tap water after supercharging again.Not only little without negative pressure and pressure oscillation in order to ensure the water that user uses, therefore, the tap water pressure that need to first ensure to input pressurized pump station import is constant, and the tap water pressure directly providing by 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, thereby not reach pressurized pump station import tap water pressure be constant perfect condition.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(), in the time that the tap water of 3kgf/cm2 pressure enters in tank, the gentle bag pressure dynamic balance of tap water, does not act on mutually; In the time that 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 taken away by water 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 proposes a kind of city tap-water pipe network end without negative pressure stable-pressure device, for being arranged on the end of municipal tap water pipe network, guarantee in user pipe without negative pressure.
To achieve these goals, the utility model adopts following technical scheme: a kind of city tap-water pipe network end is without negative pressure stable-pressure device, comprise tap water pipe network outlet pipe, vacuum tank, barrier film capsule and pressurized pump station, the inwall of vacuum tank is the cavity that holds aqueous water; In vacuum tank, be provided with at least one telescopic barrier film capsule, this barrier film capsule outer walls contacts with aqueous water, is filled with at least nitrogen of 3kgf/m2 in barrier film capsule, and the inflation inlet of barrier film capsule is fixed on the sidewall of vacuum tank; The water inlet of vacuum tank is connected with the outlet pipe of city planting ductwork, and the delivery port of vacuum tank is connected with the water inlet of pressurized pump station.
The utility model arranges barrier film capsule in vacuum tank, the nitrogen in barrier film capsule is not contacted with the water in vacuum tank, thereby nitrogen can not run off; Simultaneously in the time that the fluid pressure in tank changes, due to barrier film capsule dilatation at any time, thereby the pressure differential in compensating tank in time, ensure in user pipe without negative pressure.
As further improvement of the utility model, above-mentioned barrier film capsule is two.
Brief description of the drawings
Fig. 1 is that master of the present utility model looks, broken section structural representation.
Wherein: 1 tap water pipe network outlet pipe, 2 vacuum tanks, 3 barrier film capsules, 4 nitrogen, 5 pressurized pump stations, 6 aqueous waters, A vacuum tank water inlet, B vacuum tank delivery port, C pressurized pump station water inlet, D pressurized pump station delivery port, E inflation inlet.
Detailed description of the invention
Taking barrier film capsule as two as example by reference to the accompanying drawings detailed description of the invention of the present utility model being elaborated.
As shown in Figure 1, the present embodiment comprises tap water pipe network outlet pipe 1, vacuum tank 2, barrier film capsule 3 and pressurized pump station 5, and the inwall of vacuum tank 2 forms the cavity that holds aqueous water 6; Vacuum tank water inlet A is connected with tap water pipe network outlet pipe 1, and vacuum tank water outlet B is connected with pressurized pump station water inlet C; In vacuum tank 2, be provided with two barrier film capsules 3, these barrier film capsule 3 use nontoxic rubbers are made; Vacuum tank 2, barrier film capsule 3 entirety completely cut off with air; The inflation inlet E of barrier film capsule 3 is arranged on the sidewall of vacuum tank 2, and its inside is filled with the nitrogen 4 of 3kgf/m2.
The present embodiment, at the interior barrier film capsule 3 that arranges of vacuum tank 2, the nitrogen 4 in barrier film capsule 3 is not contacted with the water in vacuum tank 2, thereby nitrogen 4 can not run off; Simultaneously in the time that the fluid pressure in tank changes, due to barrier film capsule 3 dilatation at any time, thereby the pressure differential of compensation voltage stabilizing tank 2 in time, the pressure at vacuum tank water inlet A place is remained under the state of 3kgf/m2, thereby ensured from the water of pressurized pump station delivery port D output without negative pressure and pressure substantially constant.
