Abstract
The utility model relates to a water tank ventilating joint of solar energy water heater for connecting the water tank and prolonging soaking time of hot water in the water tank of solar energy water heater. The joint is a valve piece composed of a superior and an inferior one-way valves; wherein, a valve body has the interface connected with the water tank; the upper end of the superior one-way valve is communicated with atmosphere and the lower end with the water tank; the upper end of the inferior one-way valve is communicated with the water tank and the lower end with atmosphere. When in use, pressure difference needed to open the one-way valve should be adjusted in advance; with the water temperature in the water tank is rising, the inferior one-way valve closes automatically, and the superior one-way valve opens to exhaust air when pressure difference between the pressure inside the water tank and atmospheric pressure exceeds the adjusted value; when discharging water, with negative pressure appearing in the water tank, the superior one-way valve closes and the inferior one-way valve opens to make air entered into the water tank. The utility model effectively avoids the problem of fast cooling of hot water for frequent air release and substantially prolongs soaking time of hot water in the water tank, thereby having the advantages of simple structure, safe use, convenient installation and low cost.
Description
Technical field
The utility model relates to domestic-heating system used unit or component technology field, especially relates to the exhaust inflator of solar water heater water tank.
Background technique
The present solar water heater that uses, its water tank generally all is connected to intake pipe, outlet pipe, spill pipe, breathing pipe; Breathing pipe communicates with atmosphere, and when the water tank temperature rising, the water tank internal air pressure rises, and gas promptly can be discharged from breathing pipe; When discharging water, water tank level descends, and the water tank internal air pressure is reduced to negative pressure, and can mend into air this moment from breathing pipe, the water inlet of automatic control device instruction simultaneously, and water tank is unlikely blasts or shrivels thereby protected; But this structure, daytime, water temperature raise in the water tank under solar radiation, owing to breathing pipe directly is communicated with atmosphere, the continuous exhaust of water tank, to night, the very fast reduction of the hot water temperature in the water tank, holding time is short.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, a kind of solar water heater water tank ventilating joint to be provided, can prolonging the holding time of hot water in the solar water heater water tank effectively.
For achieving the above object, the technical solution of the utility model is such: a kind of solar water heater water tank ventilating joint, by two valve members that one-way valve is formed up and down, it has a valve body, the ventilation interface of this valve body and solar water heater water tank joins, the upper end of last one-way valve communicates with atmosphere, and the lower end communicates with water tank; The upper end of following one-way valve communicates with water tank, and the lower end communicates with atmosphere; Regulate one-way valve in advance and open required pressure reduction, the water tank water temperature raises, and following one-way valve is closed automatically, and when the difference of pressure in the water tank and atmospheric pressure surpassed this setting value, last one-way valve was opened exhaust; When discharging water, negative pressure appears in water tank, last closed check valve, following one-way valve opens, water tank air inlet.
Owing to adopted technique scheme, a kind of solar water heater water tank ventilating joint of the present utility model, can avoid water tank to cause the situation of the very fast cooling of hot water effectively because of constantly exitting, the holding time of hot water in the water tank is prolonged greatly, and have simple in structure, characteristics safe in utilization, easy for installation, that cost is low.
