Abstract
The utility model relates to a semi-closing type automatic air inlet/outlet valve. The utility model is characterized in that the utility model is composed of a valve body (1), an upper valve sheet (2), and a lower valve sheet (4), wherein, the upper and the lower valve sheets are arranged in the inner cavity of the valve body. The utility model is characterized in that hot water is discharged by means of automatic air inlet, and cold circulating water is complemented by means of automatic air outlet, which causes the hot water to be discharged out by once or several times to use. The utility model overcomes the defects that when the hot water is discharged and the air is vented at all times, a water tank can not keep the temperature, and when the water is complemented timely at all times, the hot water is cooled. The utility model enhances the effect of temperature preservation of a water storage tank.
Description
The utility model relates to the cistern device of solar water heater, specifically a kind of semi-enclosed automatic air intake and discharge valve.
Its structure of existing domestic solar water heater's water storage box is generally sealed type, and its deficiency is not mend cold water then not put hot water, has mended the cold water hot water of having had a shower again; Or in can putting hot water constantly, the exhaust loss heat from opening wide has constantly been cut down the due function of water heater again.
The purpose of this utility model provides a kind of intake and exhaust problem that can solve the sealed type water heater, avoids that positive negative pressure is too high to make water tank distortion or damaged, also can emit hot water during not moisturizing, and the semi-enclosed automatic air intake and discharge valve of loses heat not.
This practical purpose is achieved in that by valve body 1, upward valve block 2, lower valve 4 constitute, and last lower valve places body cavity.Also a ball float can be set between last lower valve.
Its principle is that valve is used for water storage box, when opening naturally, last valve block emits hot water, go up valve block when again circulating water being supplied and close naturally, lead to and natural circulation with water in the heat collector thereby reach the water of dress in the water storage box, and water follow or not the circulation time ball float all float on the highest.When water was expired state, the come-up sheet can not opened.Therefore increase thermal insulation property effectively, improved the thermal efficiency significantly.
Below in conjunction with accompanying drawing the utility model is described in further detail, but is not limited to shown in the accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the full phase diagram of water of the present utility model
As shown in Figure 1, the utility model by valve body 1, go up valve block 2, lower valve 4 constitutes, last lower valve places body cavity, and a ball float 3 (need not also can) also can be set between last lower valve.The body cavity diameter is greater than the accent diameter, and following accent has screw thread, and air hole 5 is arranged on the lower valve.
During use, air inlet and exhaust valve is fitted in tighten on the screw of water storage box loam cake and gets final product.Ball float when discharging valve is opened in the valve body goes out according to the hydraulic pressure that sewer stockpiles, and sink to naturally on the lower valve add water state.When the last valve block that avales became semi-closed state, the air of getting in the valve then pore of gap on lower valve of ball float and valve body was pressed in the water storage box, has supplied with the required air that discharges water naturally.Air when adding water in the case can be discharged from the pore on the lower valve, water through pore ball float floating to semiclosed last valve block until with its whole sealings, thereby reach insulation and avoid gas that water storage box is pressed phenomenon askew and that suction is flat.
The characteristics of air inlet and exhaust valve of the present utility model are to utilize auto-admission to emit hot water, automatically Cool circulation water is supplied in exhaust, and is incubated not loses heat. It has solved the intake and exhaust of water storage box Problem can be divided once hot water or is all discharged several times use, has saved the plating pipe of mending draining, Simplify technology, remedied constantly ventilative putting hot water and not being incubated of water tank, and constantly moisturizing And the defective of the hot water of having a shower, improved the heat insulation effect of water storage box.
Claims (4)
1, a kind of semi-enclosed automatic air intake and discharge valve is characterized in that by valve body (1), goes up valve block (2), lower valve (4) formation, and last lower valve places body cavity.
2, air inlet and exhaust valve according to claim 1 is characterized in that the body cavity diameter greater than the accent diameter, and following accent has screw thread.
3, air inlet and exhaust valve according to claim 1 is characterized in that having on the lower valve air hole (5).
4, air inlet and exhaust valve according to claim 1 is characterized in that also can being provided with ball float (3) between last lower valve.
