Problems solved by technology

Although the one-time economic cost of this scheme is not high, it is mainly used for the initial installation of solar water heaters. The problem of restricting the exhaust, because common household solar water heaters are non-pressure water heaters, and only one overflow port and exhaust port are left in the water tank. If there is foreign matter blocking the overflow port or the air circulation at the overflow port is not smooth, the water tank will The internal air cannot be replenished immediately, and the pressure difference between the inside and outside of the water tank will cause the water tank to collapse

Abstract

The invention discloses a pipe-freezing-proof device of a solar water heater. The pipe-freezing-proof device comprises a heat-preservation water tank. The upper end of the heat-preservation water tank is provided with a sensor socket, the lower end of the heat-preservation water tank is provided with a water conveying pipe, the upper end of the water conveying pipe is provided with an electromagnetic valve, the lower end of the water conveying pipe is provided with a hot water valve and a tap water valve, the lower end of the electromagnetic valve is connected with a tee joint, and the sensor socket is communicated with the tee joint through a gas guide pipe. The electromagnetic valve is a normally-closed electromagnetic valve. The pipe-freezing-proof device of the solar water heater is simple in structure, suitable for various solar water heaters, effectively solves the freezing-proof problem of the solar water heater in winter and greatly saves electricity when compared with the prior art.

Description

technical field [0001] The invention relates to an antifreeze pipe device, which is suitable for the field of solar water heaters. Background technique [0002] Since a part of the water delivery pipe of the solar water heater is always placed outdoors, in the cold winter, the water in the water delivery pipe will freeze, and the water delivery pipe will be blocked in the lightest case, and the solar water heater will no longer be used in winter, and the water delivery pipe will be frozen and cracked in severe cases. Using solar water heaters, and when the temperature rises, the leakage of the water pipes will cause water waste and pipe replacement problems. For this reason, some families empty the water in the solar water tanks and their pipes before the water pipes freeze in winter, or turn on the solar water heaters. The hot water tap dripped slowly. The utilization efficiency of solar water heaters is too low in winter, and some manufacturers also sell heating tapes for...
