Abstract

The invention relates to a decompression protection device, in particular to a double decompression protection device for a quick hot water faucet, which comprises an end cover at one end of a faucet body. A round hole a is arranged on the end cover, a decompression file is positioned on the outer side of the round hole a, a decompression block of a hollow box-body structure is fixedly arranged on the inner side of the round hole a, a contact wall between the decompression block and the end cover is provided with a hole communicated with the round hole a, the other wall is provided with a hole b, a thimble is arranged in the hole b, and the hole b is sealed from the inside to the outside through the spring. The decompression protection device is ingeniously provided with the decompressionblock of the hollow box-body structure and the decompression film. Steam can be exhausted out of the faucet under impact of steam pressure in the faucet through the decompression block and the decompression film, thereby avoiding explosion caused by steam pressure in the faucet.

Description

technical field [0001] The invention relates to a pressure relief protection device, in particular to a double pressure relief protection device for an instant hot water faucet. Background technique [0002] Now as people's living standards are getting better and better, the use of various devices is becoming more and more convenient. In the cold winter, when you turn on the tap, you can get hot water in a short time. This kind of convenience can only be realized by using water heaters and solar energy in the past, which brings great inconvenience to installation and pipe connections. Now there are new fast-heating faucets on the market, and most of them heat the tube in a short period of time by energizing to achieve the fast-heating effect. The existing instant hot water faucet in this aspect only has a single leakage or overvoltage and overheating protection device inside. When the temperature is low in winter, the water in the pipeline freezes and other factors, the int...
