Abstract
The utility model discloses a low pressure water tank of balcony wall hanging type solar water heater. A flow switch is mounted on a water outlet pipe; a normal close solenoid valve and a pressure release valve are mounted on the water inlet pipe; a controller is connected between the flow switch and the normal close solenoid valve. The water tank of the utility model achieves the advantages of long service life, high safety and high reliability; can prolong the service life of the inner tank of a water tank by 3 to 5 times.
Description
Technical field
The utility model relates to a kind of solar water heater, especially relates to a kind of balcony wall-hanging solar water heater low pressure tank.
Background technology
The balcony wall-hanging solar water heater is gone through development in several years, it all is the totally-enclosed pressure-bearing type of water tank and heat collector, whenever water temperature rises 10 ℃, to produce 1 ㎏ pressure, like this, the necessary energy of water tank and heat collector pressure-bearing 10 ㎏, the inner water tank long-term work is at artesian condition, if enamel has crackle,, make inner water tank shortening in service life at first from the cracks corrosion.
Summary of the invention
The purpose of this utility model is: at the problem and shortage that prior art exists, provide a kind of long service life, safe and reliable balcony wall-hanging solar water heater low pressure tank.
The technical solution of the utility model is: comprise storage tank, water inlet pipe, outlet pipe, water inlet pipe is connected with the inner bag below of storage tank, outlet pipe is connected with the inner bag top of storage tank, storage tank has upper circular tube and following circulation pipe, flow switch is housed on the outlet pipe, normally closed solenoid valve and relief valve are housed on the water inlet pipe, connect controller between flow switch and the normally closed solenoid valve.
The setting pressure of the utility model relief valve is 2 ㎏.
The beneficial effects of the utility model are: when using hot water, open the hot water valve on the outlet pipe, hot water flows through from flow switch, flow switch is opened, give magnetic valve voltage by controller, normally closed solenoid valve is opened, cold water begins to enter water tank from water inlet pipe, hot water is ejected, for using hot water.When using up hot water, close the hot water valve on the outlet pipe, flow switch cuts out, and cuts off power of electromagnetic valve by controller, and normally closed solenoid valve is in normally off, does not have intake pressure in the water tank, therefore, is low pressure in the water tank.Rising along with temperature in the water tank produces pressure, and when pressure rose to 2 ㎏, relief valve began pressure release, and when pressure was lower than 2 ㎏, relief valve quit work, and carried out so repeatedly.The utility model long service life, safe and reliable, can make improve 3-5 doubly the service life of inner water tank.
Description of drawings
Fig. 1 is the structural representation of the utility model balcony wall-hanging solar water heater low pressure tank.
The specific embodiment
From the structural representation of the utility model wall-hanging solar water heater low pressure tank shown in Figure 1 as can be seen, comprise storage tank 1, water inlet pipe 7, outlet pipe 5, water inlet pipe 7 is connected with the inner bag below of storage tank 1, outlet pipe 5 is connected with the inner bag top of storage tank 1, cold water enters from water inlet pipe 7, and hot water is ejected from outlet pipe 5.Storage tank 1 has upper circular tube 2 and following circulation pipe 3, in order to connect solar thermal collector.Flow switch 4 is housed on the outlet pipe 5, normally closed solenoid valve 8 and relief valve 9 are housed on the water inlet pipe 7, relief valve 9 is arranged on the water inlet of storage tank 1, the setting pressure of relief valve 9 is 2 ㎏, when pressure rises to 2 ㎏, and relief valve 9 beginning pressure releases, when pressure was lower than 2 ㎏, relief valve 9 quit work.Connect controller 6 between flow switch 4 and the normally closed solenoid valve 8, by the interlock of controller 6 control flow switches 4 and normally closed solenoid valve 8.
Operation principle of the present utility model is: when using hot water, open the hot water valve on the outlet pipe, hot water flows through from flow switch 4, flow switch 4 is opened, give magnetic valve voltage by controller 6, normally closed solenoid valve 8 is opened, cold water begins to enter water tank from water inlet pipe 7, hot water is ejected, for using hot water.When using up hot water, close the hot water valve on the outlet pipe, flow switch 4 cuts out, and cuts off power of electromagnetic valve by controller 6, and normally closed solenoid valve 8 is in normally off, does not have intake pressure in the water tank, therefore, is low pressure in the water tank.Rising along with temperature in the water tank produces pressure, when pressure rises to 2 ㎏, and relief valve 9 beginning pressure releases, when pressure was lower than 2 ㎏, relief valve 9 quit work, and carried out so repeatedly.
