Description
Technical field
The utility model relates to a kind of solar water heater emptying antifreezing valve.
Background technique
Solar water heater is meant the water heater that heats as the energy with solar energy.Be and one of gas water-heater, electric water heater three big water heaters mutually arranged side by side.Solar water heater is converted into heat energy to solar energy, and water is heated to high-temperature from low temperature, uses to satisfy the hot water of people in life, production.For easy to use, the exhaust-valve that is connected with water pipe is installed on the water tank of solar water heater, the exhaust-valve of conventional construction generally comprises valve body, be provided with water-inlet cavity and water chamber in the valve body, be provided with valve rod in the water chamber, valve rod one end is equipped with the valve plug that cooperates with the wall slipper seal of water chamber chamber, and valve rod slides along water chamber chamber wall by the drive mechanism valve plug that is arranged in the body cavity.When valve rod promoted valve plug and detaches water cavity under drive mechanism, exhaust-valve was opened, and tap water just flows in the solar water container by exhaust-valve.When valve rod was drawn in valve plug in the water chamber under drive mechanism, exhaust-valve was in closed condition.Close tap water this moment, the water in the exhaust-valve just flows out under action of gravity automatically, has played antifreeze effect.The tradition exhaust-valve, simple in structure, control is convenient, and deficiency is, driving mechanism is arranged in the body cavity, not only safeguards inconvenience, and after long-term the use, driver part is corroded easily, and grow incrustation scale easily, and cause transmission malfunctioning, shortened the working life of exhaust-valve greatly.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure at above-mentioned deficiency, and control is convenient, long service life, and solar water heater emptying antifreezing valve simple to operate.
For solving the problems of the technologies described above, this solar water heater emptying antifreezing valve comprises valve body, be provided with water-inlet cavity and water chamber in the valve body, be provided with valve rod in the water chamber, valve rod one end is equipped with the valve plug that cooperates with the wall slipper seal of water chamber chamber, its structural feature is: valve body middle part is provided with the connection chamber that is obliquely installed with water-inlet cavity or water chamber and water-inlet cavity and water chamber are connected together, valve body is provided with the valve rod hole that cooperates with valve rod middle part slipper seal, the valve rod the other end passes valve rod hole and extends to the valve body outside, and the axially movable control mechanism of actuate valve stem is installed on the valve body.
The solar water heater emptying antifreezing valve of this structure is to realize that by the external control structure control is convenient, long service life, and simple to operate.
The external control structure mainly comprises the connection chamber that is arranged in the valve body, and connection chamber is connected together water-inlet cavity and water chamber.Because the length direction of connection chamber and water chamber length direction or be obliquely installed with the water-inlet cavity length direction, so stagger in the position of water-inlet cavity and water chamber, like this, when the valve rod hole that the valve rod in the water chamber cooperates by slipper seal extended out in valve body, the water-inlet cavity of valve rod outer end and valve body was partly kept apart.The control mechanism that cooperates with the valve rod transmission is installed on the valve body, just can actuate valve stem moves vertically by handling control structure.Like this, the inner valve plug of installing of valve rod just can slip in the water chamber, close the function of this solar water heater emptying antifreezing valve to realize the sealing water chamber, perhaps in water chamber, skid off, the function of opening this solar water heater emptying antifreezing valve to realize connecting water chamber is controlled very simple.Because the driven portion of control mechanism and valve rod all is arranged on the valve body outside, avoided the corrosion of water and gathering of incrustation scale, improved structure stability and working life greatly.
As a kind of implementation, described control mechanism comprises the tooth bar that is arranged on the valve body outer valve stem, and motor is installed on the valve body, and the gear that cooperates with the tooth bar transmission is installed on the output shaft of motor.
Use motor as power take-off, it is convenient just to change counter-rotating control, and output accuracy is higher, and cost is lower.Realize the power transmission of motor and valve rod by the cooperation of wheel and rack, simple in structure, reliable transmission helps to improve working life.
As improvement, near being provided with in the valve rod of water chamber and the inner air-inlet cavity that is communicated with of valve rod, the valve rod between valve plug and the valve rod hole is provided with the inlet hole that air-inlet cavity is communicated with water chamber.
Be provided with in valve rod and the inner air-inlet cavity that is communicated with, when being installed to this solar water heater emptying antifreezing valve on the water tank, air-inlet cavity just is communicated with the atmosphere of water tank upper.Like this, when discharging water emptying, the atmosphere in the water tank just can enter in this solar water heater emptying antifreezing valve and the water pipe by air-inlet cavity and inlet hole, helps the smooth emptying of water interior in this solar water heater emptying antifreezing valve and the water pipe.
As further improvement, the magnetizer corresponding with the water chamber position is installed on the valve body.
Magnetizer has antiscale, scale removal, sterilization, algae removal, and makes big molecular water change into the physicochemical characteristics effect of change water such as micromolecular water.Use warm water after the magnetization to have a bath or wash dish, help to ensure that people's is healthy.
As improvement, the supporting frame that is slidingly matched near an end suit of gear with valve rod is installed on the valve body.
Supporting frame is installed on valve body, can be played spacing supporting effect, help to improve the axially movable stability of valve rod the valve rod outer end.
As further improvement, be set with the seal ring that cooperates with the valve rod hole slipper seal on the valve rod.
Seal ring is set, helps to improve the sealability of valve rod and valve rod hole, effectively avoid water leakage phenomenon.
In sum, adopt the solar water heater emptying antifreezing valve of this structure, rational in infrastructure, control is convenient, long service life, and simple to operate, be adapted at using on the various solar water heaters, help to improve the water reliability.
