[0028] Example

[0029] A water pressure sensor installation structure for a gas water heater, see Figure 1 At the end of the water outlet pipe 100 of the gas water heater, i.e., the water outlet end, a connection joint 10 is installed. Through the connection structure, a pipeline sensor 20 is installed. This embodiment takes a water pressure sensor as an example. In other specific embodiments, the connection joint 10 can also be set at other positions of the water outlet pipe 100, or set on the water inlet pipe. If the connection joint 10 is set in the middle of the water outlet pipe / water inlet pipe, the water outlet pipe / water inlet pipe is set into two sections, which are sealed and connected at both ends of the connection joint 10.

[0030] When the water pressure sensor is installed by using the connection joint 10, no special modification is required on the outlet pipe or the inlet pipe of the gas water heater, and only a connection joint 10 needs to be connected at a specific position. The installation of the water pressure sensor is convenient, the installation process is simplified, and the installation effect can be guaranteed.
