Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the main part in the center of the figure is the valve body 1 of the automatic anti-freezing and cracking protection valve for pipelines in the water heater. The hot water inlet 10 on the valve body 1 communicates with the water outlet pipe 82 of the water heater 80, and the hot water outlet 11 communicates with the shower ball valve 84. The water inlet 5 of the valve body 1 is connected with the tap water pipe 85, and the water outlet 6 is connected with the water inlet pipe 81 of the water heater 80; the drain port 18 of the valve body 1 is connected with the sewer pipe 86; the switch controller 83 is connected with the The electromagnetic relief valve 20 is connected to the circuit.

[0019] A piston chamber and a check valve chamber are arranged in the valve body 1 of the automatic anti-freezing crack protection valve for pipeline...

Abstract

The invention relates to the technical field of water heaters, and discloses an automatic protection valve for preventing frost cracking of an internal pipeline of a water heater. By controlling instantaneous pressure release of an electromagnetic pressure release valve, an upper valve cavity, the water heater, a water outlet, a rear cavity of a drain valve and a front cavity of the drain valve are communicated with atmosphere, so that residual water in the water heater and the internal pipeline is drained out of a water outlet under the action of dead weight. Therefore, the problem of possible frost cracking of an internal pipeline of a water heater can be fundamentally solved, the hidden danger of water leakage is eliminated, and unnecessary economic loss brought to users is avoided.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an automatic protection valve for preventing water heaters and internal pipes connected thereto from freezing and cracking. Background technique [0002] Water heaters have become an indispensable appliance when people take a bath, especially when the weather is cold, water heaters, especially electric water heaters, can quickly provide hot water for people to take a bath. In order to be more convenient for people to use, the water inlet pipe of the water heater is usually connected with the tap water pipe. When the user needs hot water for bathing, as long as the ball valve of the shower is opened, the hot water will gushe out immediately. When the bath is over and the user closes the ball valve of the shower, some water will always remain in the water heater and the inner pipeline connected thereto. But when the temperature drops sharply, especially in winter in the nort...
