Abstract
The utility model discloses a simple automatic air makeup device for pressure water tank, relating to a water supply equipment, which is a device automatically filling air to pressure water tank to make up the air in the tank losing for various causes. An air makeup tank is arranged in series between the water pump and the pressure water tank, which presses the air from the air makeup tank into the pressure water tank each time the pump starts. A non-return air inlet valve is arranged on the makeup tank. When the pump stops, air comes in automatically resulting from the negative pressure formed in the makeup tank. This process repeats and air is automatically filled into the pressure water tank. When the air in the tank comes up to the design level, the air relief valve automatically releases air, maintaining the effective water capacity in the pressure water tank.
Description
Technical field: the utility model relates to water supply equipment, especially a kind of simple and easy automatic air supply device of pressure water pot.
Background technique: at present in the hydrotechny equipment; pressurized tank device commonly used; mostly be to utilize the compressible principle of gas; adopt tank body top gas storage; the method of below water storage so that jar in the volume water inlet of gas the time obtain compression, gas pressure discharges the water that makes in the tank body to line transportation during shutdown; restart machine when pressure is low to moderate setting value and in jar, draw water, move in circles.The defective that this technology exists is: because gas has water-soluble characteristic, adds the sealing problem on upper tank body top, jar interior gas can be reduced gradually, thus the pressure duration of influence jar interior water, and then influence is supplied water.
Summary of the invention: in order to overcome the drawback that gas can reduce gradually in the existing pressure water pot jar, the utility model provides a kind of simple and easy automatic air supply device of pressure water pot, and above-mentioned drawback is solved.
The technical solution adopted in the utility model is: the automatic air supply tank of connecting between pressure of supply water jar and water pump, utilize air supply tank to store air, when each starting mode of pump draws water, the automatic extruding of air in the air supply tank is entered the press water jar, if the air in the pressure water pot is when additional too much, then have to be arranged on height and the corresponding valve air relief of design water level (special valve that venting does not discharge water) realization automatic deflation on the tank body, guarantee that air maintains in the predetermined volume in the jar.
The beneficial effects of the utility model are, the pressure water pot replenishes air automatically, makes the function of pressure water pot continual and steady, and quality of water supply is guaranteed.
Description of drawings
Accompanying drawing is a kind of structure principle chart of simple and easy automatic air supply device of pressure water pot.
Reaching embodiment in conjunction with the accompanying drawings further specifies as follows:
In the accompanying drawings, 1. submersible pump, 2. intake pipe, 3. air supply tank automatically, 4. breather check valve, 5. unidirectional outlet valve, 6. pressure water pot, 7. contact type pressure gauge, 8. safety valve, 9. bleed valve, 10. water supply line
Shown in the accompanying drawing in the specific embodiment; the keying of submersible pump (1) is controlled by contact type pressure gauge (7); during each startup submersible pump (1); water enters air in automatic air supply tank (3) and the compressed tanks from intake pipe (2); breather check valve (4) is closed; air enters pressure water pot (6) by unidirectional outlet valve (5) and replenishes a jar interior air; when the pressure in the pressure water pot (6) reaches contact type pressure gauge (7) setting value; submersible pump (1) is shut down; water in the intake pipe (2) is let out in that action of gravity is following; automatically form negative pressure in the air supply tank (3); breather check valve under the barometric pressure effect (4) is opened; gas enters automatic air supply tank (3), starts when drawing water once more, repeats above process.When the air quantity in the pressure water pot (6) reaches the volume of design, reentrant air will be discharged automatically from bleed valve (9), guarantee the actual volume of pressure water pot (6).
Claims (4)
1. the simple and easy automatic air supply device of a pressure water pot is the supplementary equipment of water system, and the air that replenish to reduce in trend press water jar is characterized in that: the automatic air supply tank of connecting between pressure of supply water water pot and water pump.
