Abstract
The utility model discloses a negative-pressure-free water supply device for a solar water heater. The device comprises a steady flow tank and a water pump, wherein a water inlet is formed at the top part of the steady flow tank; a water outlet is formed at the bottom part of the steady flow tank; the water inlet is connected with a tap water pipe; the water outlet is connected with the water pump; a pressure gage and a floating ball-type automatic air intake and exhaust valve are arranged on the steady flow tank; the floating ball-type automatic air intake and exhaust valve comprises a floating ball and a guide hole with the size matched with the outer diameter of the floating ball; a limit hole is formed at the bottom end of the guide hole; the diameter of the limit hole is larger than that of the guide hole; and the floating ball-type automatic air intake and exhaust valve can automatically adjust the air amount in the steady flow tank according to the pressure in the steady flow tank to remove the negative pressure. In the utility model, the floating ball-type automatic air intake and exhaust valve controls the air pressure in the steady flow tank, so that the air can be automatically compensated, the negative pressure is removed, and the side effect of excessive pumping and suction is avoided.
Description
Technical field
The utility model relates to a kind of non-negative pressure method of water supply device that is used for solar water heater.
Background technology
Along with the reinforcement of everybody environmental consciousness and the energy scarcity problem of increasingly sharpening, solar water heater has entered daily life.The storage tank of prior solar water heater occurs in water supply process easily owing to excessively aspirating the phenomenon that produces negative pressure, and this makes that solar water heater can't continue to supply water, and serious also may cause conduit failure.
The utility model content
At the problem that existing situation exists, the purpose of this utility model is to provide a kind of non-negative pressure method of water supply device that is used for solar water heater that can eliminate negative pressure automatically.
For achieving the above object, a kind of non-negative pressure method of water supply device that is used for solar water heater of the utility model, comprise current stabilization jar and water pump, the top of current stabilization jar is provided with water inlet, the bottom is provided with delivery port, water inlet links to each other with running water pipe, delivery port links to each other with water pump, the current stabilization jar is provided with Pressure gauge and the automatic air intake-exhaust valve of ball float type, the automatic air intake-exhaust valve of ball float type comprise ball float and with the suitable pilot hole of ball float external diameter, the lower end of pilot hole is provided with spacing hole, the diameter of spacing hole is greater than the diameter of pilot hole, the automatic air intake-exhaust valve of this ball float type is regulated air capacity in the current stabilization jar automatically according to the pressure in the current stabilization jar, to eliminate negative pressure.
The utility model is controlled the air pressure in the current stabilization jar by the automatic air intake-exhaust valve of ball float type, can be in time make-up air automatically, eliminate negative pressure, avoid the excessively side effect of suction.
Description of drawings
Accompanying drawing is the utility model structural representation.
Wherein Reference numeral is as follows:
Current stabilization jar 1, water pump 2, water inlet 3, delivery port 4, running water pipe 5, Pressure gauge 6, the automatic air intake-exhaust valve 7 of ball float type, ball float 71, pilot hole 72, spacing hole 73.
The specific embodiment
As shown in drawings, a kind of non-negative pressure method of water supply device that is used for solar water heater of the utility model, comprise current stabilization jar 1 and water pump 2, the top of current stabilization jar 1 is provided with water inlet 3, the bottom is provided with delivery port 4, water inlet 3 links to each other with running water pipe 5, delivery port 4 links to each other with water pump 2, current stabilization jar 1 is provided with Pressure gauge 6 and the automatic air intake-exhaust valve 7 of ball float type, can in time observe pressure in the current stabilization jar 1 by Pressure gauge 6, the automatic air intake-exhaust valve 7 of ball float type comprise ball float 71 and with the suitable pilot hole 72 of ball float external diameter, the lower end of pilot hole 72 is provided with spacing hole 73, the diameter of spacing hole 73 is greater than the diameter of pilot hole 72, and is rounding off between the inwall of pilot hole 72 and spacing hole 73.
When the air pressure in the current stabilization jar 1 descended, atmospheric pressure compressing ball float 71 pilot hole 72 of postponing moved downward, in the time of in ball float 71 runs to spacing hole 73, the automatic air intake-exhaust valve 7 of ball float type is opened, thereby with current stabilization jar 1 and ambient atmosphere conducting, automatic make-up air is to eliminate negative pressure.After current stabilization jar 1 internal pressure was stable, by pouring into of water in the running water pipe 5, ball float 71 upwards ran in the pilot hole 72, with 1 sealing of current stabilization jar.
