[0002] A temperature measuring ball valve is a type of valve with temperature measurement and control functions. It is widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation and rocket industries. During use, impurities in the medium can easily cause blockage.

[0003] Chinese patent publication number CN201232766Y discloses a temperature measuring ball valve. This utility model connects the valve body to the handle by extending the valve stem through the outer end. A temperature-conducting component is provided at the bottom of the valve body, allowing the bottom of the ball valve to have an opening and a temperature sensor installed. This enables accurate measurement of the internal temperature of the ball valve and allows for simultaneous operation of fluid opening / closing and temperature measurement.

[0004] The aforementioned device achieves its temperature measurement function by setting up a temperature sensor during use. During the placement of the sensor, the bottom limiting device alone can limit the sensor and block it, but it cannot improve the stability of the sensor. This makes the contact position of the sensor inside unstable, which can easily affect the accuracy of temperature monitoring data and thus affect the performance of the temperature measuring ball valve. Optimization and improvement are needed. Utility Model Content

The clamping and positioning assembly is used for clamping and positioning the temperature sensor. The connection and adjustment assembly is located outside the valve body and includes a connection end. An internal threaded tube is located inside the connection end, and a positioning insertion ring is located inside the internal threaded tube. The connection and adjustment assembly is used for connecting and adjusting the external pipeline.

[0008] Preferably, the threaded connector is threaded to the bottom inner side of the mounting tube, and a plug is connected to the bottom of the threaded connector. A sealing gasket is provided on the outside of the plug, and a rubber ring is provided on the inside of the threaded connector.

[0009] Preferably, the fixing ring is fixedly connected to the inner side of the placement tube, and a rotating connecting block is connected to the inner side of the fixing ring.

[0010] Preferably, the side-rotating clamping block is rotatably connected to the inner side of the rotating connecting block, and the top of the rotating connecting block is connected to an elastic connector.

[0011] Preferably, the connecting end is fixedly connected to the outside of the valve body, and the inner side of the connecting end is provided with internal threads.

[0012] Preferably, the built-in threaded tube is threaded to the inside of the connection end, and a sealing gasket is connected to the outside of the built-in threaded tube.

[0013] Preferably, the inner wall of the built-in threaded tube is provided with a turning groove, and the positioning insertion ring is welded to the inner side of the built-in threaded tube.

[0014] Preferably, the rotating connecting block and the side rotating clamping block are rotatably connected, and the side rotating clamping block and the elastic connecting member are elastically connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention improves the stability of temperature sensor installation and ensures the accuracy of temperature sensor detection data by setting a side-rotating clamp block on the inside of the installation tube to clamp and position the temperature sensor side, and then pressing and fixing the bottom end with a rubber ring on the inside of the threaded joint.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 4 As shown, this application provides a temperature measuring ball valve, including: a valve body 1, a valve stem 2 connected to the inner side of the valve body 1, a handle 3 connected to the top end of the valve stem 2, a mounting tube 4 connected to the bottom end of the valve body 1, and a temperature sensor 6 disposed on the inner side of the mounting tube 4.

[0026] The inner side of the placement tube 4 is provided with a clamping and positioning component, which includes a threaded joint 9. The inner side of the threaded joint 9 is provided with a rubber ring 10, and the top of the rubber ring 10 is provided with a fixing ring 11. The inner side of the fixing ring 11 is provided with a side rotation clamping block 13. The clamping and positioning component is used for clamping and positioning the temperature sensor 6.

[0027] Specifically, such as Figure 2 As shown, the threaded connector 9 is threaded to the inner bottom end of the placement tube 4, and the bottom end of the threaded connector 9 is connected to the plug 7. A sealing gasket 8 is provided on the outer side of the plug 7, and a rubber ring 10 is provided on the inner side of the threaded connector 9. The threaded connection between the threaded connector 9 and the placement tube 4 facilitates the positioning of the plug 7. During positioning, the sealing gasket 8 improves the sealing effect of the connection, and the rubber ring 10 improves the stability of the connection at the bottom end of the temperature sensor 6.

[0028] Specifically, such as Figure 3As shown, the fixing ring 11 is fixedly connected to the inner side of the placement tube 4, and the inner side of the fixing ring 11 is connected to the rotating connecting block 12. The side rotating clamping block 13 is rotatably connected to the inner side of the rotating connecting block 12, and the top of the rotating connecting block 12 is connected to the elastic connecting member 14. The rotating connecting block 12 and the side rotating clamping block 13 are rotatably connected, and the side rotating clamping block 13 and the elastic connecting member 14 are elastically connected. The rotating connecting block 12 and the side rotating clamping block 13 are rotatably connected. The top outer side of the side rotating clamping block 13 is fixedly connected to the rotating connecting block 12 through the elastic connecting member 14. The elastic force of the elastic connecting member 14 makes the side rotating clamping block 13 have an inclined angle, so that the clamping space of the side rotating clamping block 13 is wider at the bottom and narrower at the top, which facilitates clamping and positioning when the temperature sensor 6 is pushed upward, and ensures the stability of the temperature sensor 6.

[0029] A connection adjustment assembly is provided on the outer side of the valve body 1. The connection adjustment assembly includes a connection end 5. An internal threaded tube 16 is provided on the inner side of the connection end 5. A positioning plug ring 19 is provided on the inner side of the internal threaded tube 16. The connection adjustment assembly is used for the connection adjustment of external pipelines.

[0030] Specifically, such as Figure 4 As shown, the connecting end 5 is fixedly connected to the outside of the valve body 1, and the inner side of the connecting end 5 is provided with an internal thread 15. The internal thread 15 can be directly connected to the external pipe, or it can be filled by the built-in threaded pipe 16 when the external pipe is thin.

[0031] Specifically, such as Figure 4 As shown, the built-in threaded tube 16 is threaded to the inside of the connecting end 5, and the outside of the built-in threaded tube 16 is connected to a sealing gasket 2 17. After filling, the built-in threaded tube 16 can be sealed by the sealing gasket 2 17 connected at both ends to improve the sealing performance of the connection.

[0032] Specifically, such as Figure 4 As shown, the inner wall of the built-in threaded tube 16 is provided with a turning groove 18, and the positioning plug-in ring 19 is welded to the inner side of the built-in threaded tube 16. The setting of the turning groove 18 facilitates the rotation of the built-in threaded tube 16, and the turning groove 18 can be plugged into a suitable rotating tool.

[0033] In this embodiment: a side-rotating clamping block 13 is provided on the inner side of the placement tube 4 to clamp and position the side of the temperature sensor 6. Then, the bottom end is tightly pressed and fixed by the rubber ring 10 on the inner side of the threaded joint 9, which can improve the stability of the installation of the temperature sensor 6 and ensure the accuracy of the temperature sensor 6 detection data. When connecting the pipe on the outer side of the connection end 5, the connection of the built-in threaded tube 16 can facilitate the connection of different types of pipes. Then, the positioning insertion ring 19 is set to facilitate the tight pressing and fixing when the pipe is inserted.

[0034] Specifically, this solution involves the following steps: During the use of the temperature measuring ball valve, the valve stem 2 and the internal valve ball are controlled by rotating the handle 3 to adjust the opening and closing of the valve body 1. The temperature sensor 6 inside the mounting tube 4 is used for temperature monitoring. To improve the stability of the temperature sensor 6 installation, a rotatable and elastically supported side-rotating clamp 13 is used to clamp the side of the temperature sensor 6. The bottom end is connected to a rubber ring 10 via a threaded connector 9 for tight adjustment, ensuring the stability of the temperature sensor 6 connection and the accuracy of the temperature monitoring data. When the valve body 1 is connected to an external pipeline, an internal thread 15 allows for direct connection to the external pipeline. Alternatively, when the external pipeline is thin, it can be filled using an internal threaded tube 16. The internal threaded tube 16 has a ground-shifting groove 18 for inserting a suitable rotating tool, facilitating the installation and removal of the internal threaded tube 16. Without the use of specific tools, it is difficult to adjust the internal threaded tube 16, which also means that the connection stability of the internal threaded tube 16 can be guaranteed.
