[0002] Sensors, such as temperature sensors, water pressure sensors, water flow sensors, etc., are commonly used in fluid pipelines to detect fluid parameters such as temperature, pressure, and flow. For example, a contact temperature sensor, whose detection part is in contact with the object being measured, achieves thermal equilibrium through conduction or convection, so that the indication of the thermometer can directly represent the temperature of the object being measured, and has the advantage of high measurement accuracy. It is widely used in various fields.

[0003] Gas water heaters are one of the application areas. They are installed on pipelines to detect parameters such as water pressure and temperature of the fluid flowing in the pipeline.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example

[0030] A mounting structure such as Figure 1-Figure 3 As shown, the mounting member 300 of this embodiment is a temperature sensor as an example, and the temperature sensor is mounted on the fluid pipeline 100 through the mounting structure 200. The fluid pipeline 100 has a fluid channel, and the purpose of the installed temperature sensor is to detect the temperature of the fluid in the fluid channel.

[0031] In this embodiment, the mounting structure 200 includes a body 21 mounted on the fluid pipeline 100 and a fixing assembly 22. The body 21 is cylindrical and has a mounting channel 21a that runs through in the longitudinal direction (the height direction of the body 21) and communicates with the fluid channel of the fluid pipeline 100. The body 21 is fixed on the outer surface of the fluid pipeline 100, and the fixing method can be welding, screw fixing, etc. The mounting structure can also be set to a structure that is preset to be integrated with the fluid pipeline 100. A small through hole is opened on the fluid pipeline 100, and the temperature sensor is installed in the mounting channel 21a, and the front end extends into the fluid channel through the through hole to contact the fluid and detect the fluid temperature.

[0032] The body 21 of the mounting structure 200 can be directly mounted on the fluid pipeline 100 by opening a through hole in the fluid pipeline 100 as described above. However, this method requires destroying the original fluid pipeline 100, which is inconvenient to operate.

[0033] This embodiment also provides another method of indirectly installing the body 21 on the fluid pipeline 100 through a connecting joint 500. Figure 2 , 3 As shown, the connecting joint 500 can be installed at the end of the fluid pipeline 100. The connecting joint 500 is tubular, and has a connecting channel 51 inside, which is connected to the fluid channel fluid of the fluid pipeline 100. A circular through hole 52 is opened on the wall of the connecting joint 500, which is connected to the installation channel 21a for the front end of the installation part to extend into. The body 21 is connected to the connecting joint 500 in a fixed manner. More preferably, the body 21 and the connecting joint 500 are integrally formed. The two exist in the form of a kit. When in use, it is more convenient to install only by installing the connecting joint 500, and there is no need to drill additional holes in the fluid pipeline 100.

[0034] In this embodiment, the entire mounting structure 200 is mounted on the water outlet pipe of the gas water heater through the connecting joint 500. The temperature sensor is mounted and fixed by a fixing assembly 22 that cooperates with the body 21. The fixing assembly 22 includes an elastic member 22a installed in the mounting channel 21a and a fixing member 22b installed on the temperature sensor 300. In this embodiment, the fixing member 22b includes a plurality of fixing keys, and the elastic member 22a is a spring.

[0035] In this embodiment, the structure of the temperature sensor is as follows: Figure 4 As shown, the whole is roughly cylindrical, including a functional part 31 at the front end, a widened part 32 located behind the functional part 31, and a tightening part 33 located behind the widened part 32. The diameter of the widened part 32 is larger than the diameter of the functional part 31 and also larger than the diameter of the tightening part 33. A fixed key is provided at the upper part of the widened part 32, which is directly integrated with the widened part 21. The number of fixed keys is two, three, or four, etc. In this embodiment, four are preferably used, and they are evenly distributed along the circumferential direction of the widened part 21. The diameter of the through hole 52 on the connecting joint 500 is smaller than the outer diameter of the spring, and smaller than the diameter of the widened part 32, to ensure that the spring is confined in the installation channel 21a. The outer diameter of the spring is slightly smaller than the diameter of the widened part 32. With this design, the widened part 32 can exert a relatively stable pressure on the spring.

[0036] In this embodiment, if Figure 5As shown, four introduction and fixing grooves 21b are opened on the inner wall of the upper part of the body 21, corresponding to the fixing keys. Each introduction and fixing groove includes a vertically arranged introduction groove 21b-1, a fixing groove 21b-2 located on one side of the introduction groove 21b-1, and a connecting groove 21b-3 connecting the introduction groove 21b-1 and the fixing groove 21b-2. The entrance of the introduction groove 21b-1 is located on the end surface of the body 21.

[0037] In this embodiment, if Figure 2 As shown, a limiting groove is provided on the widened portion 32, and the fixing key is installed through the limiting groove, so that when the temperature sensor is rotated, the fixing key is more stable and firm.

[0038] In a specific embodiment, an annular groove 32a is formed on the outer surface of the lower portion of the widened portion 32, and a sealing ring 400 is sleeved in the annular groove 32a. In the installed state, the sealing ring 400 abuts against the inner surface of the installation channel 21a to achieve sealing.

[0039] During installation, place the spring into the installation channel 21a of the main body 21, insert the temperature sensor 300 with a fixed key into the installation channel 21a, align the fixed key with the entrance of the introduction groove 21b-1, and apply a downward force to the temperature sensor. When the fixed key reaches the bottom of the introduction groove 21b-1 (at this time, continuing to apply force will not move the temperature sensor downward), gently turn the temperature sensor in the direction of the connecting groove 21b-3. When the fixed key reaches the bottom of the connecting groove 21b-3 (at this time, continuing to apply force will not move the temperature sensor), release the external force on the temperature sensor 300. Under the action of the spring, the temperature sensor 300 moves upward until the fixed key reaches the top of the fixing groove 21b-2, and the installation of the temperature sensor is completed.

[0040] When the temperature sensor needs to be removed, apply downward force to the temperature sensor. When the fixing key reaches the bottom of the fixing groove 21b-2, rotate the temperature sensor in reverse until the fixing key reaches the end of the connecting groove 21b-3. Release the external force on the temperature sensor. Under the action of the spring, the temperature sensor moves upward, and the temperature sensor can be removed.

[0041] The above operation process is simple and convenient, and the installation structure can fix the temperature sensor stably.
