Abstract

The utility model discloses an air inlet and outlet respirator for a solar water heater, which comprises a connecting pipe (1) with a channel (11) inside, and a valve plate ( 2), the cross-section of the valve plate (2) coincides with the cross-section of the channel (11). Installing the solar water heater inlet and outlet respirator at the exhaust pipe of the solar water heater can avoid heat exchange between the hot air in the water tank and the cold air outside when the water heater does not use water.

Description

Inlet and outlet respirator for solar water heater

technical field

The utility model relates to a respirator for air in and out of a solar water heater.

Background technique

Existing solar water heater water tank inlet and outlet air exhaust pipes are all directly connected to the outside world, and the open end of the exhaust pipe is facing downwards. It is impossible to avoid the exchange of hot air in the water tank with cold air outside without using water. resulting in heat loss. People are eager to install a kind of adjustment control device at the exhaust pipe place, and this device can avoid the heat exchange between the hot air in the water tank and the cold air of the outside under the situation that water heater does not use water.

Utility model content

The technical problem to be solved by the utility model is to provide a solar water heater inlet and outlet air respirator, which can be installed at the exhaust pipe of the solar water heater to avoid hot air in the water tank when the water heater does not use water. Exchange heat with the cold outside air.

In order to solve the above technical problems, the utility model provides a solar water heater inlet and outlet respirator, which includes a connecting pipe with a channel inside, and a valve plate connected to the channel in rotation, the cross section of the valve plate and the channel The cross-section is consistent.

As the improvement of the solar water heater inlet and outlet respirator of the present utility model: the connecting pipe is a plastic pipe with a length of 5 to 10 cm.

The solar water heater air inlet and outlet respirator of the utility model is installed at the exhaust pipe of the solar water heater during actual use, so that the connecting pipe is fixedly connected with the open end of the exhaust pipe. When the solar water heater is not in and out of water, there is no gas flow in the exhaust pipe. Therefore, the valve plate is parallel to the cross section of the channel, so the entire channel is closed, thereby avoiding heat exchange between the hot air in the water tank and the cold air outside. , that is, to block heat loss. Only when the solar water heater enters or exits the water, the channel is in the open state, that is, the air in and out is kept unimpeded; the details are as follows: when the solar water heater enters the water, the exhaust pipe discharges the gas outward, and the valve plate is downward under the impact of the airflow Turn over, so that the channel is in an open state; or when the solar water heater is out of water, the exhaust pipe sucks inward, and the valve plate is turned upward under the impact of the air flow, so that the channel is in an open state.

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the sectional structure schematic diagram of solar water heater inlet and outlet air respirator of the present utility model;

Fig. 2 is a schematic top view of Fig. 1;

Fig. 3 is a schematic diagram of Fig. 1 when the solar water heater is in a state of water intake;

Detailed ways

Fig. 1～Fig. 2 combined provides a kind of air inlet and outlet respirator of solar water heater, comprises a connecting pipe 1 with passage 11 inside, and this connecting pipe 1 is a plastic pipe, and the length is 5～10cm.

A valve plate 2 is arranged in the channel 11, and only one end point of the valve plate 2 is fixedly connected with the channel 11, so the valve plate 2 and the channel 11 are connected in rotation. The cross section of the valve plate 2 matches the cross section of the channel 11 .

In actual use, the solar water heater inlet and outlet respirator of the present utility model is located below the exhaust pipe 3 of the solar water heater, and the connecting pipe 1 is fixedly connected to the opening end of the exhaust pipe 3 in a sealed manner; therefore, it can be designed as a connecting pipe 1 The outer diameter is equal to the inner diameter of the exhaust pipe 3, so that the connecting pipe 1 is sleeved in the exhaust pipe 3.

When the solar water heater is not in and out of water, there is no gas circulation in the exhaust pipe 3, so the valve plate 2 is parallel to the cross section of the channel 11, so the entire channel 11 is in a closed state, as shown in Figure 1; thus avoiding the water tank The hot air inside exchanges heat with the cold air outside, that is, to block heat loss. Only when the solar water heater is in or out of water, the channel 11 is in the open state, that is, to keep the air in and out; the details are as follows: when the solar water heater is in water, the exhaust pipe 3 discharges the gas outward, and the valve plate 2 is under the impact of the airflow Turn up and down (as shown in Figure 3), so that the channel 11 is in an open state; or when the solar water heater discharges water, the exhaust pipe 3 inhales inwardly, and the valve plate 2 is turned up under the impact of the air flow, so that the channel 11 is opened. 11 is in an open state (as shown in Figure 4).

Finally, it should also be noted that what is listed above is only a specific embodiment of the present invention. Apparently, the utility model is not limited to the above embodiments, and many variations are possible. All deformations that a person skilled in the art can derive or associate directly from the content disclosed in the utility model shall be considered as the protection scope of the utility model.

Claims (2)

1. The solar water heater inlet and outlet respirator is characterized in that it includes a connecting pipe (1) with a channel (11) inside, and a valve plate connected to the channel (11) in rotation is provided in the channel (11) (2), the cross-section of the valve plate (2) coincides with the cross-section of the channel (11). 2. The solar water heater inlet and outlet respirator according to claim 1, characterized in that: the connecting pipe (1) is a plastic pipe with a length of 5-10 cm.
