Abstract

The invention relates to a gas secondary pressure detection mechanism, a gas distributor and a gas water heater. The gas secondary pressure detection mechanism comprises a detection device body, a connecting and fixing piece and a sealing ring, wherein a gas path channel and a detection hole are arranged in the detection device body, and the gas path channel is used for making the detection hole communicate with a gas main channel in the gas distributor. The detection device body is provided with an exhaust port communicating with the detection hole, the connecting and fixing piece is connected with the detection device body, the sealing ring is extruded to seal the exhaust port, and the detection device body is provided with a limiting part used for limiting the movement distance of the connecting and fixing piece in the direction of extruding the sealing ring. When the connecting and fixing piece is matched with the limiting part for limiting, the ratio of the compression amount delta h of the extruded sealing ring to the thickness H1 of the sealing ring in a natural state is within a rated ratio range. Therefore, the compression amount of the sealing ring is within a reasonablerange, and the situation that the sealing ring is damaged and loses sealing performance after being excessively extruded and deformed in the disassembling and assembling process is avoided.

Description

technical field [0001] The invention relates to the technical field of water heater components, in particular to a gas secondary pressure detection mechanism, a gas distributor and a gas water heater. Background technique [0002] A gas water heater is a water heater that uses the heat provided by the combustion of gas in a burner to heat water to provide hot water for users. The gas distributor is assembled on the burner to control whether each nozzle of the burner is connected. In order to ensure the normal and reliable operation of the gas water heater, the gas pressure entering the gas distributor needs to be within a reasonable range. Therefore, a secondary pressure detection mechanism will be provided on the gas distributor to determine whether the gas pressure entering the gas distributor is within a reasonable range by detecting the pressure at the detection hole of the secondary pressure detection mechanism. After the detection is completed, the detection hole is ...
