Abstract
The invention relates to a bidirectional ventilation device capable of reducing heat loss of a water tank of a solar water heater. The bidirectional ventilation device comprises a body, an air outlet port valve, an air outlet, an air inlet and an air inlet valve, wherein an air inlet and outlet channel is disposed inside the body, a boss is disposed in the air inlet and outlet channel, the air inlet and the air outlet are arranged on the boss, the air outlet valve is fixedly connected onto the body, the top end of the air outlet valve is abutted to the upper end of the air outlet, and the air outlet valve is hermetically connected with the air outlet. The air conduction direction of the air outlet valve and the air conduction direction of the air inlet valve are opposite, and each of the air outlet valve and the air inlet valve is conducted in the single direction. The air outlet valve can be automatically opened to exhaust air when the internal pressure of a water tank is higher than the external pressure of the water tank and the difference between the internal pressure and the external pressure reaches a certain pressure value, and the air inlet valve can be automatically opened to suck air when the internal pressure of the water tank is lower than the external pressure of the water tank and the difference between the internal pressure and the external pressure reaches a certain pressure value, so that air is supplemented into the water tank.
Description
Technical field
The present invention relates to a kind of air interchanger of solar water heater, particularly a kind of two-way air interchanger that reduces the solar water heater water tank heat loss.
Background technique
All be provided with outlet pipe in the water tank of solar water heater, when the solar water heater water tank pressure inside became big, air compressed can be discharged through opening wide outlet pipe, play hypotensive effect, prevented that pressure is excessive and destroyed water tank liner; After the water tank water level inside descended, when its internal pressure reduced, air can enter into water tank inside from the exhaust duct that opens wide, and keeps the water tank internal pressure, thereby prevented that water tank from being taken out flat; Because the exhaust duct of general water tank setting is in opening-wide state always; Even if in the inside and outside differential pressure range that allows; It is not in running order basically; Water temperature in the water tank can cause damage owing to opening wide of exhaust duct, has influenced the heat insulation effect of solar water heater to a great extent.
Summary of the invention
Technical problem to be solved by this invention provides a kind of energy-conserving and environment-protective, and is simple in structure, can effectively improve the two-way air interchanger of the solar water heater of solar water container heat utilization efficiency.
Solve the problems of the technologies described above, the present invention realizes as follows: the two-way air interchanger of a kind of solar water heater of the present invention comprises body, air outlet valve body, air outlet, suction port and suction port valve body; Said body interior is provided with turnover gas passage, is provided with boss in the turnover gas passage, and boss is provided with suction port and air outlet; Said air outlet valve body is fixedly connected on the body, and its top abuts against the upper end of air outlet, and the two formation is tightly connected; Said suction port valve body is fixedly connected on the body, and its top abuts against the lower end of suction port, and the two formation is tightly connected.
The gas conducting direction of air outlet valve body and suction port valve body is opposite, and all is unidirectional conducting; Greater than external pressure, and can open automatically and carry out exhaust when reaching the certain pressure value by inside and outside differential pressure in the water tank internal pressure for the air outlet valve body, thereby can prevent effectively that the water tank internal pressure is excessive and cause water tank liner to damage; Less than external pressure, and inside and outside differential pressure is when reaching the certain pressure value in the water tank internal pressure for the suction port valve body, can open automatically to carry out air-breathingly, promptly carries out tonifying Qi in the water tank, thereby can prevent effectively that the water tank internal pressure is too small and it is flat to cause water tank to be inhaled; In the scope that the water tank inside and outside differential pressure allows; Air outlet valve body and suction port valve body all are in off position; Promptly all be in closed state; Thereby this device not only can be guaranteed the normal use of solar water heater, and can also reduce to a great extent because of outlet pipe and be in the heat loss that opening-wide state causes always.
Good effect of the present invention: the two-way air interchanger of a kind of solar water heater according to the invention, through setting out gas port valve body and suction port valve body, realized two-way ventilation; In the scope that the water tank inside and outside differential pressure allows, air outlet valve body and suction port valve body all are in closed state, reduce to a great extent because of outlet pipe to be in the heat loss that opening-wide state causes always; Improved solar energy utilization rate fully; Energy-conserving and environment-protective meet the strategy of national green energy resource, suitablely promote widely.

Embodiment
As depicted in figs. 1 and 2; Solar water heater generally comprises water tank (7), intake pipe (9), outlet pipe (8) and heat collecting pipe (10) etc.; The two-way air interchanger of a kind of solar water heater of the present invention is arranged at the upper end of solar water heater water tank (7); Can play the effect of air inlet-outlet pipe, it comprises body (1), air outlet valve body (2), air outlet (3), suction port (4) and suction port valve body (5); Said body (1) inside is provided with turnover gas passage (11), is provided with boss (6) in the turnover gas passage (11), and boss (6) is provided with suction port (4) and air outlet (3); Said air outlet valve body (2) is fixedly connected on the body (1), and its top abuts against the upper end of air outlet (3), and one-way sealing is carried out in air outlet (3); Said suction port valve body (5) is fixedly connected on the body (1), and its top abuts against the lower end of suction port (4), and suction port (4) is carried out one-way sealing.
Air outlet valve body (2) is opposite with the gas conducting direction of suction port valve body (5), and all is unidirectional conducting; Greater than external pressure, and can open automatically and carry out exhaust when reaching the certain pressure value by inside and outside differential pressure in water tank (7) internal pressure for air outlet valve body (2), thereby can prevent effectively that water tank (7) internal pressure is excessive and cause water tank liner to damage; Suction port valve body (5) in water tank (7) internal pressure less than external pressure; And when inside and outside differential pressure reaches the certain pressure value; Can open automatically and carry out air-breathingly, promptly carry out the interior tonifying Qi of water tank (7), thereby can prevent effectively that water tank (7) internal pressure is too small and it is flat to cause water tank to be inhaled; In the scope that water tank (7) inside and outside differential pressure allows; Air outlet valve body (2) and suction port valve body (5) all are in off position; Promptly all be in closed state; Thereby this device not only can be guaranteed the normal use of solar water heater, and can also reduce to a great extent because of outlet pipe and be in the heat loss that opening-wide state causes always.
Some principles of work and power of the two-way air interchanger of a kind of solar water heater that the present invention that just explains through diagrams recited above is correlated with; Owing to concerning the technician in constructed field, be easy to carry out on this basis some modifications; Therefore this specification do not really want two-way air interchanger with a kind of solar water heater of the present invention be confined to shown in or in described concrete mechanism and the Applicable scope; So every modify that possibly be utilized and equivalent, all belong to the protection domain of patent of the present invention.
