Abstract
The utility model discloses an air pressure canister, which comprises a shell. Wherein, the bottom of the shell is provided with a water outlet. The utility model is characterized in that: the shell is provided with a rubber diaphragm inside; the rubber diaphragm divides the internal air in the shell into a water storage chamber and an air storage chamber; an air inlet is provided on the air storage chamber and the air storage chamber is positioned on the upper part of the water storage chamber. Compared with the prior art, the utility model has the following advantages that: the utility model can make the water pump of the frequency conversion water supply equipment work internally, reduce the wear and tear of the water pump, prolong the service life of the water pump and save the energy; the air storage chamber is positioned on the upper part of the water storage chamber, which avoids the uneven stress of the rubber diaphragm due to the deadweight of the water; the proper volume of the air pressure canister can prolong the sleep time of the water pump and can not waste the capital, which is convenient for maintenance.
Description
Technical field
The utility model relates to the local supply device, specifically a kind of air pressure tank of frequency conversion water supply facilities.
Background technology
To family or similar applications local supply device, the air pressure tank that mixes by the original adoption air water and then change the diaphragm type air pressure tank that water, gas are separated into.This diaphragm type air pressure tank has the long-term advantage of using of once inflation.And air water does not contact, and can guarantee that water quality is not contaminated, reduces the corrosion of water to tank body, prolongs tank body application life.At present the diaphragm type air pressure tank of using adopts the scrotiform barrier film of the less and middle huge jujube nuclear shape of the identical and diameter of upper and lower opening diameter more, because the deadweight effect of water makes the diaphragm of rubber discontinuity, has reduced the application life of barrier film.The patent No. is 85203272, denomination of invention provides a kind of new types of diaphragm formula air pressure tank that is used for the local supply device for the Chinese utility model patent of " diaphragm type air pressure tank ", it is characterized in that the scrotiform barrier film is spherical in shape or go up the date core shaped young, that end opening is big, can prolong the application life of barrier film like this, increase the hydroecium volume.Its weak point is still thoroughly not solve because the deadweight effect of water makes the problem of diaphragm of rubber discontinuity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of application life that prolongs barrier film to society, is applicable to the air pressure tank of frequency conversion water supply facilities.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of air pressure tank comprises housing, in the bottom of housing one delivery port is arranged, it is characterized in that a rubber diaphragm is arranged in the described housing, described rubber diaphragm is divided into reservoir chamber and air storage chamber with the enclosure interior space, and an air inlet is arranged on air storage chamber, and described air storage chamber is positioned at the top of reservoir chamber.
The further technical scheme of the utility model is:
The capacity of described reservoir chamber is 35～50L.
Because the utility model has been taked above-mentioned technical measures, it compared with prior art has following advantage:
1, the water pump discontinuous operation of frequency conversion water supply facilities be can make, water pump loss, prolongation water pump life-span, energy conservation reduced;
2, air storage chamber is positioned at the top of reservoir chamber, has avoided because the deadweight effect of water makes the problem of diaphragm of rubber discontinuity;
3, the volume of the air pressure tank of suitable size can prolong the length of one's sleep of water pump, does not waste fund again, and is convenient to safeguard.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
With reference to Fig. 1, the utility model comprises housing 1, and a delivery port 2 is arranged in the bottom of housing 1, one rubber diaphragm 4 is arranged in the housing 1, rubber diaphragm 4 is divided into reservoir chamber 3 and air storage chamber 6 with housing 1 inner space, and an air inlet 5 is arranged on air storage chamber 6, after the inflation air inlet 5 is sealed.Air storage chamber 6 is positioned at the top of reservoir chamber 3.The capacity of reservoir chamber 3 is 35～50L.
The utility model utilizes the minimum character of water compressibility, uses external force, and promptly water pump pumps into water in the reservoir chamber 3, and the gas in the air storage chamber 6 is compressed pressure and raises; When water pump quits work, when promptly external force disappeared, the gases in the air storage chamber 6 expanded, and acted on water in the reservoir chamber 3 by rubber diaphragm 4, and water is discharged from delivery port 2.
The terminal valve of life pipe network is difficult to accomplish watertight, therefore, does not have water supply facilities or system that air pressure tank is set, keeps system pressure by the press water of pipe network self.Because the compression ratio of water is far smaller than gas, but significantly descends when pipe network has the leakage build-up of pressure of low discharge, can make the water pump frequent starting.Because the application of frequency conversion, the equipment control of pump supplies (variable constant voltage) because of need.Variable frequency control water pump low speed guarantees to utilize this point by pipe network " constant voltage " during zero delivery, and the frequency conversion water supply facilities that air pressure tank no longer is set just must have do not stop work in 24 hours work or frequent starting of a water pump to guarantee the pressure of pipe network.Therefore, the utility model can guarantee the normal rest of water pump and prolong the intermittent time.
The volume of air pressure tank depends on the water yield of replenishing pipe network in the certain pressure scope.Reveal under the certain situation of flow (L/S) at pipe network, the volume size of air pressure tank has determined water pump to restart the length of intermittent time, and volume is big more, and the intermittent time is long more; Therefore, select the big slightly air pressure tank of volume can prolong the length of one's sleep of water pump.But the excessive air pressure tank of volume also can bring negative effect: increase fund input, maintenance inconvenience, inflationtime length etc.Through calculating, it is proper selecting the air pressure tank of regulating pondage about 35～50L for use.
