Description
Affiliated technical field
The utility model relates to a kind of valve, the especially a kind of solar water heater emptying valve that water in the solar water heater water-supply-pipe can be discharged.
Background technology
Exhaust-valve is not set between boiler on traditional solar water heater and the water-supply-pipe, could obtain hot water after cold water in the water-supply-pipe need being bled off during use, not only cause the waste of water resource, and cause certain trouble to the user, for overcoming this defective, people have begun to be provided with the exhaust-valve that the water in the water-supply-pipe can be bled off between boiler and water-supply-pipe, the existing exhaust-valve that is used for solar water heater is realized that by electric motor driven conversion valve port the major defect one that the exhaust-valve of this structure exists is a complex structure, the manufacturing cost height, should not popularize; The 2nd, motor is fragile, and service life is short, maintenance cost is high.
Summary of the invention
Task of the present utility model is to provide a kind of simple in structure, low cost of manufacture, long service life, is suitable for the function that promptly has control valve that popularizes to have the novel solar water heater exhaust-valve of exhaust-valve function again.
For realizing above-mentioned task, the utility model is taked following technical scheme.The utility model comprises valve body, armature, solenoid, movable core, bucker, valve plate, spring, it is characterized in that at one end being provided with the hot water mouth, the other end is provided with in the inner chamber of valve body of water transport port and is provided with the valve port that hot water mouth and water transport port are connected, in the valve body of valve port upside, be provided with the valve chamber that can be connected with the hot water mouth, on the valve body of valve chamber upside, be positioned with the armature that side within it is provided with solenoid by screw, have through hole in the centre of the armature that is arranged in the solenoid inboard and be set with bucker at this through hole, bucker drops on the step of valve body by gasket base, be provided with spring in bucker inner chamber upper end, in the bucker of this spring downside, movable core is housed, the lower end of movable core is provided with the valve plate that has sealing gasket that is located on the valve port, be provided with the air chamber that is connected with water transport port at valve body upside near water transport port one side, be positioned with the gland that has through hole on the air chamber upper port, in this through hole, be set with the valve plate guide pillar that is provided with valve plate in its lower end, have the air guide crack on the valve plate guide pillar, suit is positioned with spring on the valve plate guide pillar of gland upside.
According to technique scheme, when the solenoid dead electricity, valve plate is located on the valve port under the effect of spring, thereby realize the task of valve-off, behind the valve closing with water-supply-pipe that water transport port is connected in water will under the effect of himself gravity, fall, make to be negative pressure state in the air chamber, move down at the effect lower valve plate guide pillar of this negative pressure, by the air guide crack on the valve plate guide pillar air chamber is connected with atmosphere, thus the task that realization can all be emitted the water in the water-supply-pipe.When solenoid was switched on, armature upwards picked up movable core under the effect of solenoid, drive on the valve plate to move, thereby the task of valve was opened in realization.When needs are given the solar water heater moisturizing, open the moisturizing valve, the stream waterborne in the water-supply-pipe, on the effect lower valve plate guide pillar of hydraulic pressure, move, cut off the air guide crack that air chamber is communicated with atmosphere, water enters in the solar water heater by valve port simultaneously, thereby realizes the task of moisturizing.Can effectively realize task of the present utility model in sum.
Owing to adopted technique scheme, the beneficial effects of the utility model one are owing to adopted negative pressure to control automatic evacuation structures, so have simple in structure, reliable, long service life, be suitable for the characteristics that popularize with the existing exhaust-valve of Motor Control; The 2nd, because control valve and exhaust-valve are designed in a valve body, so it is complete to have function, the characteristics that mounting cost is low, easy to maintenance.
