[0020] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model.

[0021] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0022] See also Figure 1-5 The utility model is a temperature-pressure integrated sensor, comprising a pressure sensor core 4, a temperature sensor core 5, a sensor ball valve body 6, and a temperature sensor waterway sleeve 7. The pressure sensor core 4 is threadedly connected to the outlet at one end of the sensor ball valve body 6. The temperature sensor waterway sleeve 7 is threadedly installed in the sensor ball valve body 6. A gap 701 is provided at the end of the temperature sensor waterway sleeve 7 extending out of the sensor ball valve body 6. The gap 701 communicates with the liquid inside the sensor ball valve body 6. A ball valve 3 is installed inside the sensor ball valve body 6. The ball valve 3 is located in the channel between the gap 701 and the pressure sensor core 4. The temperature sensor core 5 is threadedly installed inside the temperature sensor waterway sleeve 7.

[0023] Furthermore, the pressure sensor core 4 is provided with an external hexagonal screw at a position outside the sensor ball valve body 6 , and the external hexagonal screw is used to tighten or remove the pressure sensor core 4 .

[0024] Furthermore, the handle 1 of the ball valve 3 extends out of the sensor ball valve body 6 .

[0025] Furthermore, the temperature sensor core 5 is provided with an external hexagonal screw at a position outside the sensor ball valve body 6 , and the external hexagonal screw is used to tighten or remove the temperature sensor core 5 .

[0026] Furthermore, a temperature sensor waterway sleeve 7 is sleeved on the outside of the temperature sensor core 5, the temperature sensor core 5 is threadedly connected to the temperature sensor waterway sleeve 7, the temperature sensor waterway sleeve 7 is threadedly connected to the sensor ball valve body 6, and a sealing ring 2 is provided at the position where the outside of the temperature sensor waterway sleeve 7 is connected to the sensor ball valve body 6.

[0027] Furthermore, a plug-in slot 702 is provided at the upper end of the temperature sensor waterway sleeve 7, and the plug-in slot 702 is used as a force groove during connection. The plug-in slot 702 is used when installing the temperature sensor waterway sleeve 7. When the temperature sensor waterway sleeve 7 is threaded into or removed from the sensor ball valve body 6, a flat-blade screwdriver is used to apply force at the plug-in slot 702 to rotate it.

[0028] Furthermore, the temperature sensor water channel sleeve 7 is an elongated cylinder, and one end of the temperature sensor water channel sleeve 7 is an open structure.

[0029] Embodiment: The sensor ball valve body 6 is in the form of a three-way. The lower opening is the inlet of the fluid. There are two openings in the upper part, and the outlet is directly above the lower part, which is threaded and used to install the temperature sensor waterway sleeve 7. The other outlet is used to install the pressure sensor core.

[0030] The passage where the pressure sensor is installed is opened and closed by the rotation angle of the ball valve 3. When the valve ball 3 is in the open state, the liquid to be measured enters the sensor ball valve body 6 from the gap 701 between the lower part of the sensor ball valve body 6 and the temperature sensor water channel sleeve 7, and then passes through the valve ball 3 and is guided to the lower end of the pressure sensor core 4. According to the principle of pressure conduction, the pressure of the liquid at the measured position is measured. When the valve ball 3 is closed, the passage for pressure measurement can be closed.

[0031] The temperature sensor waterway sleeve 7 is installed on the sensor ball valve body 6. The top of the temperature sensor waterway sleeve 7 is located at the center line of the pipeline and contacts the center temperature of the fluid. The temperature sensor core 5 is inserted into the temperature sensor waterway sleeve 7 and isolated from the liquid. The temperature measurement point is located at the top of the temperature sensor core 5, that is, the center line of the pipeline. Through heat conduction between the temperature sensor waterway sleeve 7 and the temperature sensor core 5, the measurement point obtains the center temperature of the pipeline liquid, which achieves the rigor of the measurement.

[0032] The pressure sensor core 4 is installed at the outlet on the ball valve 3 side of the sensor ball valve body 6. The pressure of the liquid passes through the gap 701 between the temperature sensor water channel sleeve 7 and the sensor ball valve body 6, and then passes through the valve ball 3 to reach the pressure measuring point of the pressure sensor core 4 to achieve pressure measurement. The gap 701 on the pressure sensing path can reduce sudden pressure shocks and protect the pressure sensor core 4. By turning the handle on the ball valve body 90°, the ball valve 3 can be closed, that is, the pressure measurement path is closed. The temperature sensor core 5 is isolated from the liquid and can be directly replaced; after closing the pressure measurement path, the pressure sensor core 4 can be replaced.
