Description
Technical field: the invention belongs to technical field of solar water heaters, relate to a kind of closed solar water heater water tank protective valve, especially relate to a kind of water-heater water tank anti-pumping valve.
Background technology: present improving constantly along with people's living standard, the application of solar water heater more and more widely, especially northern area almost is that every household is had a bath with solar water heater or done washing winter, scrubs life appliance etc., and particularly closed solar water heater generally is subjected to people's favor.But in the winter of cold, closed solar water heater water tank often makes because of there's a sudden fall in temperature and forces down in the water tank in atmospheric pressure, causes water tank to be flattened or is called " taking out flat ", and influence result of use.
Summary of the invention: the technical problem to be solved in the present invention is when there's a sudden fall in temperature in the winter time and cause closed solar water heater water tank to take out flat technical problem, and a kind of solar water heater water tank is anti-takes out flat protective valve thereby provide.
For solving the problems of the technologies described above, the present invention has taked following technical scheme: it comprises valve body, valve gap and valve body connector, body cavity is provided with the below that dividing plate is positioned at the body cavity boss, be provided with negative pressure piston, malleation piston, positive pressing spring and spring capping that negative pressure spring, piston rod are provided with strip groove on the dividing plate successively, be equipped with pore on dividing plate, spring capping and the valve gap.
Said dividing plate is spill, and the size of concave bottom surface is corresponding with negative pressure spring lower end, and the pore on the dividing plate is 6, evenly is located on the concave crown face.
The pore of said spring capping is located at the center of spring capping, and its diameter is less than the diameter of positive pressing spring.
Pore on the said valve gap is 4, evenly is located at the periphery in the valve gap, is groove shape.
Said negative pressure piston is convex, one circular groove is arranged at the bottom on the negative pressure piston rod, size is corresponding with the upper end of negative pressure spring, and the strip groove on the negative pressure piston rod evenly is provided with 4 at its periphery, and negative pressure piston head bottom surface diameter is slightly less than the peripheral diameter of dividing plate concave crown face pore.
Said malleation piston is the boss annular, is sleeved on the negative pressure piston head by the negative pressure piston rod, and its internal diameter size is corresponding with the diameter of negative pressure piston rod, and its external diameter is slightly larger than the diameter of body cavity boss, and malleation piston bottom periphery is corresponding with the body cavity boss.
During use, anti-pumping valve of the present invention is vertically mounted on the top of solar water heater water tank, the valve body connector is communicated with water tank.When the pressure of water in the water tank is higher than setting pressure, the malleation piston is by jack-up, positive pressing spring upwards shrinks, malleation piston bottom surface breaks away from the body cavity boss, steam in the water tank enters valve pocket by the gap of the pore on valve body connector, the dividing plate, negative pressure piston head sides and body cavity boss, discharge through the pore of centre porosity on the valve gap periphery of spring capping again, make to press in the water tank to maintain setting pressure; When the pressure of water in there's a sudden fall in temperature the water tank is lower than external atmosphere pressure, the negative pressure descent of piston, the negative pressure spring shrinks downwards, the gap appears in negative pressure piston head and malleation piston bottom surface, outside air enters valve pocket along the pore of valve gap periphery by the spring capping centre porosity, pass through the strip groove on the negative pressure piston rod periphery again, the gap of negative pressure piston head and malleation piston bottom surface, the gap of negative pressure piston head sides and body cavity boss, by the pore on the dividing plate, the valve body connector enters water tank, replenish an amount of air, make the interior pressure of water tank identical, avoided water tank to be shriveled by atmosphere with ambient pressure.
Modern design of the present invention, rational in infrastructure, in the time of preventing the winter temperature rapid drawdown effectively, solar water heater water tank is taken out flat phenomenon.
