Abstract
The utility model relates to a feeding and drainage combined valve of a solar water heater. A valve body is provided with a water inlet and a water outlet, and a feeding control valve is arranged on the water outlet of the valve body. The valve body is also provided with a water pressure control interface. A piston arranged in the valve body controls the conduction and the closing of the water inlet and the water outlet, and simultaneously cuts off the conduction between the water pressure control interface in the valve body and the water inlet. The vicinities of the water pressure control interface and the water inlet are respectively provided with a drainage gas return valve. The utility model has the functions of the automatic closing of feeding and draining water in water pipes when needed and is particularly suitable for being used in the cold weather environment.
Description
The utility model relates to a kind of control valve that uses in solar water heater, refer in particular to a kind of solar water heater water combination valve up and down.
At present, the solar water heater of selling on the market all has a water storage tank, is connected to a upper hose and an overflow pipe on water tank, wait until during last water that the water storage of water storage tank is full after, when water refluxes from overflow pipe, manually close water supply valve.Also there is on water storage tank one of configuration can close the into control valve of water automatically, solved the automatic control of water on the water storage tank.But the upper hose of above-mentioned water storage tank has water all the time in the upper hose after last intact water or use are closed, in the winter of cold, the water in the upper hose is easy to freeze, and causes the obstruction of upper hose, influences the water up and down of upper hose, and serious also can be with the upper hose bursting by freezing.
The purpose of this utility model is the problem at above-mentioned existence, propose a kind of can go up that water is closed automatically and can be when needed with the solar water heater of the water emptying in water storage tank upper hose water combination valve up and down.
The purpose of this utility model is to realize like this, solar water heater of the present utility model water combination valve up and down comprises valve body, water inlet and delivery port are arranged on valve body, water control valve on the delivery port place of valve body has, on valve body, also has a hydraulic pressure control interface, conducting between piston control water inlet and the delivery port is arranged in valve body and close, side at piston has spring, this piston cuts off the conducting between interior hydraulic pressure control interface of valve body and the water inlet simultaneously, and a draining return-air valve is respectively arranged near hydraulic pressure control interface and water inlet.Above-mentioned last water control valve is made up of ball float, connecting rod, spool and valve seat, and side sleeve pipe with holes is arranged in the outside of ball float and connecting rod, and this sleeve pipe is connected with valve seat; Above-mentioned draining return-air valve is made up of spring, steel ball and blind nut, and is porose on the blind nut.
The water combination valve is when last water about the solar water heater of the present utility model, water flows into from water inlet, under the effect of water pressure, piston moves, conducting between water inlet and the delivery port, water flows into water storage tank through last water control valve, and when the water level of water storage tank reaches certain height, spool will be gone up water control valve and close under the double action of the buoyancy of ball float and water pressure.Simultaneously, piston resets under the effect of spring, closes between water inlet and the delivery port, and after the hydraulic pressure removal of water inlet, the draining return-air valve of water inlet is opened under the effect of negative pressure, and the water in the water inlet pipe can discharge.When needing water, the place imposes certain hydraulic pressure at the hydraulic pressure control interface, and piston is moved, water in the conducting between water inlet and the delivery port, water storage tank can flow out, when the hydraulic pressure removal of hydraulic pressure control interface, piston resets again, water inlet and delivery port are closed, and the draining return-air valve at hydraulic pressure control interface place is opened under suction function, and the water in the water pipe is emitted.Therefore, solar water heater of the present utility model up and down the water combination valve have and can go up that water is closed automatically and can be particluarly suitable for using in the arctic weather environment when needed with the function of the water emptying in the water pipe.
Description of drawings:
Fig. 1 is the solar water heater of the present utility model structural representation and the pipeline catenation principle figure of water combination valve up and down.
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, solar water heater of the present utility model water combination valve up and down comprises valve body 2, water inlet 18 and delivery port are arranged on valve body 2, water control valve on the delivery port place of valve body 2 has, on valve body 2, also has a hydraulic pressure control interface 1, conducting between piston 7 control water inlets 18 and the delivery port is arranged in valve body 2 and close, side at piston 7 has spring 13, this piston 7 cuts off the conducting between valve body 2 interior hydraulic pressure control interfaces 1 and the water inlet 18 simultaneously, and a draining return-air valve is respectively arranged near hydraulic pressure control interface 1 and water inlet 18.Above-mentioned last water control valve is made up of ball float 9, connecting rod 10, spool 12 and valve seat 11, in the outside of ball float 9 and connecting rod 10 side sleeve pipe with holes 8 is arranged, and this sleeve pipe 8 is connected with valve seat 11; Above-mentioned draining return-air valve is made up of spring 8 and 17, steel ball 4 and 16, blind nut 6 and 14, on the blind nut 6 and 14 porose 5 and 15.
