Description
Technical field
The present invention relates to a kind of fresh and alive devices of water body in the technical field of supply equipment more particularly to holding air pressure tank.
Background technique
Secondary water-supply equipment is varied in structure and control mode, and " water pump group+frequency conversion is relatively mostly used in structure
The form of power control cabinet ".In general difference is supplied at regular time and quantity with domestic water, domestic consumption change curve is larger, and
With apparent time response, therefore, living water equipment should have " multi-purpose water, more power consumptions；Less with water, few power consumption " energy conservation
Feature.
Air pressure tank is the precondition that water pump can enter sleep, will with external force using the minimum property of the compressibility of water
Water is stored in tank, and gas is increased by compression pressure, when external force disappearance expansion of compressed gas can exclude water, due to the pressure of water
Contracting is than being far smaller than gas, when the leakage that pipe network has small flow can cause stress a sharp decline, can make water pump frequent starting,
If general pump directly supplies water to user, it must be just equipped with air pressure tank, alleviate water pump frequent starting.
Existing air pressure tank is mainly made of valve cap, inflating port, air bag, tank body, ring flange, when it is connected in water system
When, mainly play an accumulator, when system water pressure is greater than the nitrogen pressure between tank body and air bag, system water meeting
It is squeezed into air bag under the action of system pressure, in this way first is that the nitrogen between tank body and air bag can be compressed, reduces its volume,
Pressure increases；Second is that will increase the accommodation space of the entire water of system, reduce system pressure, until the pressure and tank body of system water
Nitrogen pressure between air bag reaches new balance and just stops water inlet.When system water pressure is less than gas pressure in tank, gas
Intracapsular water can squeeze out under the pressure effect of nitrogen between tank body and air bag, refill system, system water capacity reduces pressure
Power rises, and the nitrogen volume between tank body and air bag increases pressure decline, and until the two reaches new balance, water stops from air bag
System is squeezed back, pressurized tank plays the role of regulating system pressure oscillation.
In actual use, it is found that water pressure fluctuations very little because water pressure fluctuations are small passes in and out the water of air pressure tank in air pressure tank
Amount is corresponding to be reduced, and commonly uses the water inlet of air pressure tank, water outlet in same place, this is resulted in air pressure tank only close to Inlet and outlet water
The water in water energy and water supply network at mouthful swaps, and most of water in air pressure tank cannot replace for a long time, is easily formed
Stagnant water, and the stagnant water microorganism easy to breed that the residence time is too long causes secondary pollution to water to keep water putrid and deteriorated.

Illustrate the working principle of the invention below:
As shown in figure 3, when the pressure in the gas chamber 5 that water supply network hydraulic pressure is greater than air pressure tank 1, under the action of water pressure, into
First spring 15 of water cavity check-valves 11 is compressed, and the first flap 14 is moved along water inlet guide post 13 to one end close to air pressure tank 1,
Intake antrum check-valves 11 is opened, and water supply network supplies water into the water chamber 4 of air pressure tank 1, at this point, water chamber check-valves 12 is closed
It closes.
As shown in figure 4, when the pressure in the gas chamber 5 that water supply network hydraulic pressure is less than air pressure tank 1, in the gas chamber 5 of air pressure tank 1
Gas expansion, air bag 3 compressed, and the water in the water chamber 4 of air pressure tank 1 is supplied to water supply network, at this point, water chamber check-valves 12
Second spring 18 compressed, the second flap 17 is moved along water outlet guide post 16 to far from one end of air pressure tank 1, water chamber check-valves
12 are opened, and air pressure tank 1 supplies water to water supply network, at this point, intake antrum check-valves 11 is closed.
When supplying water sufficient, the intake antrum check-valves 11 of double check valve 7 is opened, since the water in water supply network is passing through
When the intake antrum 9 of double check valve 7, according to bernoulli principle, area of passage reduces, and water flow velocity increases, by high flow rate, through into
The water of water cavity 9 can flow to the top of the water chamber 4 of air pressure tank 1, the i.e. one end of air pressure tank 1 far from double check valve 7.As shown in Figure 5.
When user with water is less or the water supply of water supply network is inadequate when, the water chamber check-valves 12 of double check valve 7 is opened, air pressure
Water in the water chamber 4 of tank 1 close to water outlet is supplemented to outlet pipe 22 through the water chamber 4 of double check valve 7, to meet user's need
It asks.As shown in Figure 6.
In conjunction with Fig. 5 and Fig. 6, when supplying water sufficient, the water flow velocity for flowing into air pressure tank 1 is big, can flow to the water chamber 4 of air pressure tank 1
Top, when small flow water or insufficient water, the bottom of the water chamber 4 of air pressure tank 1 close to intake-outlet water first from water chamber 4
Interior inflow outlet pipe 22, the water body into water chamber 4 realize first in first out, the water supply principle of last-in, last-out, to make air pressure tank 1
Interior water body realizes effective displacement, ensure that the fresh and alive of water body, reduces the probability of secondary pollution of water.
Operation of the present invention is simple, only need to be in the intake-outlet of air pressure tank 1 under the premise of not changing existing air pressure jar structure
It connects between the water outlet pipe network of supply equipment a double check valve 7, is fixedly connected with fastener, implements cleverer
It is living.
The present invention solves the problems, such as existing water-in and water-out secondary pollution of water present in the air pressure tank of same place, really
It protects the water energy in use process in air pressure tank and obtains Rapid replacement, keep water body fresh and alive.
The foregoing is merely preferred embodiments of the present invention, are not intended to limit embodiments of the present invention and protection model
It encloses, to those skilled in the art, should can appreciate that all with made by description of the invention and diagramatic content
