Abstract
The utility model relates to a ventilated check valve in solar energy water heater systems. The ventilated check valve is designed for solving the problems of automatic water intake control and fluent water outflow of a water heater water storage tank. The utility model mainly comprises a valve body, a valve plug, a sealed ring and a ball float. The ventilated check valve is installed above the water storage tank with a plumb. When the water storage tank supplies water, air in the water storage tank is automatically fluent to enter atmosphere; when the water in the water storage tank flows out, the atmosphere enters the water storage tank through the ventilated check valve to make the water is fluent. The utility model has simple structure, low cost and reliable use and is an important component for ensuring that the solar energy water heater systems can normally work.
Description
The utility model relates to a kind of ventilation cutoff valve, is mainly used in the automatic loading water system of high-order sealed mode water storage box, is specially adapted to the household water heater industry.
At present, a kind of " sealing valve " (CN90223727,6) of domestic applications patent, its structure as shown in Figure 2, it mainly contains, and valve is stifled 4, valve body 1, guiding valve 5 and O RunddichtringO 7 constitute.Its O RunddichtringO 7 maintains static with valve body 1, and valve stifled 4 and valve body 1 are fixedly connected, and guiding valve 5 slides up and down along the spline guiding groove in valve body 1 inside.Two vents that are cross are arranged on valve body top, and two vents all communicate with the full inner chamber of valve.This " sealing valve " has following shortcoming: the first, complex structure, manufacture cost height.The second, since guiding valve along the upper and lower slip of spline guiding groove, so not only make complexity, and operational safety is poor.
The purpose of this utility model is the shortcoming at above-mentioned prior art, makes simply, uses ventilation cutoff valve reliable, easy for installation, low cost of manufacture and provide a kind of.
The utility model is achieved in that it is stifled by valve body, valve, seal ring, ball float are formed.Particularly ball float adopts the table tennis of producing by international standard, and seal ring adopts the internal cones structure, on the stifled upper surface of valve vent slot is arranged.
Below in conjunction with drawings and Examples model utility is further described.
Fig. 1 is a structure sectional view of the present utility model.
Fig. 2 is the sectional view of " sealing valve ".
Among the figure: 1, valve body, 2, ball float, 3, seal ring, 4, valve is stifled, 5, guiding valve, 6, vent slot, 7, O type seal ring.
In Fig. 1, be fixedly connected between valve stifled 4 and the valve body 1, seal ring 3 outer surfaces and valve body 1 internal surface are fixedly connected, and ball float 2 can block up between 4 the end face unsteady at the internal cones of the seal ring 3 of valve body 1 inside and valve.The interior Cylinder diameter of valve body 1 and the gap between ball float 2 external diameters can be as the criterion along this gap circulation can make free upper and lower motion of ball float and air.When the internal cones cone angle of seal ring 3 floats can make ball float and internal cones closely paste sternly water-tightly, when the water surface sank, ball float can lean on gravity fall to break away from the internal cones surface to be principle automatically.Upper-end surface at valve stifled 4 has vent slot 6, and vent slot size and quantity are principle ventilating.
The outer surface of valve body 1 is a Cylinder, and internal surface is the garden cylinder of two different diameters.Ball float 2 is the thin-walled hollow spheroid, the table tennis that ball float of the present utility model is adopted international standards.Seal ring 3 outer surfaces are two different diameter garden cylinders, and internal surface is a cone.Valve stifled 4 is for outer surface is a ladder garden post, and internal surface is the cylinder pipe thread, and stifled 4 end faces of valve have vent slot 6.
During work, when the water storage box moisturizing, rely on city hydraulic pressure to make water enter water storage box automatically, air atmosphere outside this valve expulsion valve in the water storage box, after the water storage box fills with water, water floats ball float 2 and rises, after ball float 2 rises to the inner conical surface of seal ring 3, water makes ball float 2 closely paste mutually with the inner conical surface of seal ring 3 to the buoyancy of ball float, forms face contact seal because of seal ring produces resiliently deformable under the floating function of ball float transmission between the two, makes water charging system stop into water.When water heater, water flows out along inlet pipeline.Make that ball float 2 breaks away from the seal ring internal surface voluntarily and falls to stifled 4 upper surfaces of valve to the buoyancy disappearance of ball float 2, extraneous air enters in the water storage box through vent slot 6.
This implementation is novel to have following advantage: the first, and it has adopted the table tennis by the international standard manufacturing is ball float, make ball float spheroid geometric accuracy be guaranteed, and cost reduces significantly.The second, seal ring adopts the inner conical surface structure, and material is the manufacturing of middle hardness rubber, make when ball float rises easily from the concentricity line of normal moveout correction, and both contacts are the face contact, thereby making to seal is guaranteed.Three, stifled 4 upper surfaces of valve have vent slot 6, make that the water storage box water-in and water-out are unimpeded, and the employing of above technology has overcome the defective of prior art, has improved using effect.
Claims (4)
1, a kind of ventilation cutoff valve, it includes stifled 4, the valve body 1 of valve, it is characterized in that including ball float 2, seal ring 3 constitutes, valve stifled 4 is fixedly connected in valve body 1 bottom, and seal ring 3 is fixedly connected on the top of valve body 1 inside, and ball float 2 floats between stifled 4 tops of seal ring 3 bottoms, valve of valve body 1 inside.
2, ventilation cutoff valve according to claim 1 is characterized in that ball float adopts the table tennis of making by international standard.
3, ventilation cutoff valve according to claim 2, the internal surface that it is characterized in that seal ring is a cone.
