Anti-freezing rank air replenishing device of solar water heater

Abstract

The invention discloses an anti-freezing rank air replenishing device of a solar water heater, which comprises a connecting body, wherein the upper end and the lower end of the connecting body are provided with ports, the side part of the connecting part is provided with an anti-freezing rank air replenishing chamber in a communicating manner through a water inlet and outlet hole and a balance hole which are arranged on the connecting body, the anti-freezing rank air replenishing chamber is composted of a cavity body and a cavity cover, the cavity cover is provided with an exhaust hole, the cavity body is internally provided with a floating ball, the floating ball is arranged in the anti-freezing rank air replenishing chamber through a rubber location lifting ring connected to the cavity body, a floating ball guide rod connected with the upper end of the floating ball is inserted into the exhaust hole, and the lower end of the floating ball guide rod is provided with a sealing cushion. The anti-freezing rank air replenishing device can avoid air blockage before and after the solar water heater is emptied, and guarantees smooth water utilization of water.

Description

technical field [0001] The invention relates to an accessory of a solar water heater, in particular to an antifreeze exhaust and air supply device installed on the solar water heater. Background technique [0002] With the popularization of green energy, solar water heaters are becoming more and more popular. When solar water heaters are used in winter or in cold regions, freezing and cracking often occur. In order to prevent the occurrence of freezing and blocking, an emptying valve is installed at the water inlet and outlet of the solar water heater, and then the upper and lower water pipes are connected to the room. The upper and lower water pipes often form an indoor A shower head is installed behind the U-shaped pipe bend, so that the solar water heater often forms a dynamic air pressure balance at the U-shaped pipe bend before and after emptying, and an air block occurs. When the air block occurs, the user will not be able to use water. Contents of the invention [...

Problems solved by technology

When solar water heaters are used in winter or in cold areas, freezing and cracking often occur. In order to prevent the occurrence of freezing and blocking, an emptying valve is installed at the water inlet and outlet of the solar water heater and then the upper and lower water pipes are connected to the room. The upper and lower water pipes often form an indoor After the U-shaped pipe is bent, the shower head is installed, so that the solar water heater often forms a dynamic air pressure balance at the U-shaped pipe bend before and after emptying, and an air block occurs. When the air block occurs, the user will not be able to use water.
