[0001] This utility model relates to the field of temperature control valve technology, and in particular to an automatic temperature control valve. Background Technology

[0002] A temperature control valve is a type of valve that adjusts the valve opening based on the detected fluid temperature, thereby regulating the fluid flow rate and ultimately achieving temperature control. It is commonly used in fields such as chemical engineering, pharmaceutical manufacturing, and automobile production.

[0003] Existing technologies often have the following drawbacks: existing automatic temperature control valves typically use an automated valve core to control the valve opening during use, thereby adjusting the fluid flow rate. However, this adjustment method has a large adjustment range and is difficult to achieve the fine adjustment effect in pipelines with different flow requirements.

[0004] Therefore, this utility model provides an automatic temperature control valve. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing automatic temperature control valves, which typically use automated valve cores to control valve opening and adjust fluid flow. However, this adjustment method has a large adjustment range and is difficult to achieve precise adjustment in pipelines with different flow requirements. Therefore, this invention proposes an automatic temperature control valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic temperature control valve, comprising a valve body and a side tube, wherein an automatic adjustment cap is installed on the side of the side tube away from the valve body, a valve stem is installed inside the side tube, a fixed cylinder is fixedly connected to the inner wall of the side tube, a through hole is opened on the side of the fixed cylinder, an inner core is rotatably connected to the inner wall of the fixed cylinder, and six adjustment holes are opened on the side of the inner core, the six adjustment holes being evenly distributed on the side of the inner core.

[0007] The effect achieved by the above components is that, through the fixed cylinder, through hole, inner core, and six adjustment holes of different sizes, the pipeline flow rate can be preset when using the temperature control valve, thereby providing the pipeline with a matching fluid flow rate as much as possible and improving the accuracy of subsequent fluid flow rate adjustment.

[0008] Preferably, a threaded ring is fixedly connected to the side of the fixed cylinder near the automatic adjusting cap, the external thread of the threaded ring matches the internal thread of the automatic adjusting cap, and a valve cap is fixedly connected to the side of the threaded ring away from the fixed cylinder.

[0009] The effect achieved by the above components is that the fixed cylinder and the automatic adjustment cap can be connected through the threaded ring, thereby facilitating the installation and removal of the automatic adjustment cap.

[0010] Preferably, the valve cap has six graduations on the side away from the valve body, and the six graduations are evenly distributed on the side of the valve cap away from the valve body. The inner core has an indicator groove on the side near the automatic adjustment cap.

[0011] The effect achieved by the above components is that the indicator grooves and scales can improve the effect and accuracy of adjusting the inner core angle.

[0012] Preferably, the inner wall of the valve cap is fixedly connected with six clamping plates, and the six clamping plates are evenly distributed on the inner wall of the valve cap.

[0013] The effect achieved by the above components is that the set plate can achieve the effect of positioning and position restriction.

[0014] Preferably, the inner wall of the inner core is slidably connected with six slide rods, and each of the six slide rods is fixedly connected to a limiting plate at one end near the card plate. The limiting plate has a U-shaped cross-section.

[0015] The effect achieved by the above components is that, through the sliding rod, the limiting plate can move closer to or away from the card plate, thereby cooperating with the card plate to restrict the rotation of the inner core and release the restriction on its rotation.

[0016] Preferably, a control plate is fixedly connected to the side of the limiting plate near the slide rod, and the vertical cross-section of the control plate is "L" shaped.

[0017] The effect achieved by the above components is that the position of the limit plate can be easily moved through the control panel.

[0018] Preferably, each of the six slide rods is fitted with a spring, and the two ends of the spring are fixedly connected to the limiting plate and the inner core, respectively.

[0019] The effect achieved by the above components is that the springs ensure a stable connection between the limiting plate and the inner core, and also limit the position of the limiting plate.

[0020] In summary:

[0021] In this invention, the fixed cylinder, through hole, inner core, and six adjustment holes of different sizes can improve the adaptability of the temperature control valve to pipelines with different flow requirements, so as to provide the most accurate flow adjustment effect in pipelines with different flow requirements.

[0028] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: an automatic temperature control valve, including a valve body 1 and a side tube 2. An automatic adjustment cap 6 is installed on the side of the side tube 2 away from the valve body 1. A valve stem 9 is installed inside the side tube 2. A fixed cylinder 3 is fixedly connected to the inner wall of the side tube 2. A through hole 4 is opened on the side of the fixed cylinder 3. An inner core 8 is rotatably connected to the inner wall of the fixed cylinder 3. Six adjustment holes 11 are opened on the side of the inner core 8, and the six adjustment holes 11 are evenly distributed on the side of the inner core 8. By using the fixed cylinder 3, the through hole 4, the inner core 8, and the six adjustment holes 11 of different sizes, the flow rate of the pipeline can be preset when using the temperature control valve, thereby providing a matching fluid flow rate to the pipeline as much as possible and improving the accuracy of subsequent fluid flow rate adjustment.

[0029] The following is a detailed explanation of its overall setup and function.

[0030] Reference Figures 1-5As shown in this embodiment: a threaded ring 5 is fixedly connected to the side of the fixed cylinder 3 near the automatic adjusting cap 6, and the external thread of the threaded ring 5 matches the internal thread of the automatic adjusting cap 6. A valve cap 7 is fixedly connected to the side of the threaded ring 5 away from the fixed cylinder 3. The threaded ring 5 allows the fixed cylinder 3 and the automatic adjusting cap 6 to be connected, facilitating the installation and removal of the automatic adjusting cap 6. The valve cap 7 has six graduations 10 on the side away from the valve body 1, evenly distributed on this side. An indicator groove 12 is provided on the side of the inner core 8 near the automatic adjusting cap 6. The indicator groove 12 and graduations 10 improve the effect and accuracy of angle adjustment of the inner core 8. Six retaining plates 13 are fixedly connected to the inner wall of the valve cap 7, evenly distributed on this side. The retaining plates 13 provide positioning and position limiting effects.

[0031] Six sliding rods 14 are slidably connected to the inner wall of the inner core 8. Each of the six sliding rods 14 has a limiting plate 16 fixedly connected to one end near the locking plate 13. The limiting plate 16 has a U-shaped cross-section. The sliding rods 14 ensure that the limiting plate 16 can move closer to or further away from the locking plate 13, thus cooperating with the locking plate 13 to restrict and release the rotation of the inner core 8. A control plate 17 is fixedly connected to the side of the limiting plate 16 near the sliding rods 14. The vertical cross-section of the control plate 17 is L-shaped. The control plate 17 allows for easy movement of the limiting plate 16. Springs 15 are fitted onto the surfaces of the six sliding rods 14. The two ends of the springs 15 are fixedly connected to the limiting plate 16 and the inner core 8, respectively. The springs 15 ensure a stable connection between the limiting plate 16 and the inner core 8, while also limiting the position of the limiting plate 16.

[0032] Working principle: When using the temperature control valve, first connect the valve body 1, then open the automatic adjustment cap 6. The control plate 17 drives the limit plate 16 to move, so that the slide rod 14 slides on the inner wall of the inner core 8. Thus, the limit plate 16 moves away from the clamping plate 13, releasing the restriction on the rotation of the inner core 8. Then, rotate the inner core 8 and use the scale 10 on the valve cap 7 and the indicator groove 12 on the inner core 8 to adjust the angle of the inner core 8 so that the adjustment hole 11, which matches the pipeline flow requirement, is close to the through hole 4. After the preset flow is completed, release the control plate 17. Under the action of the spring 15, the limit plate 16 moves close to the clamping plate 13, restricting the rotation of the inner core 8. Then, move the automatic adjustment cap 6 close to the side pipe 2 and fix the automatic adjustment cap 6 with the threaded ring 5 so that it can automatically control the rotation of the valve stem 9. By incorporating a fixed cylinder 3, through hole 4, inner core 8, and six adjustment holes 11 of different sizes, the adaptability of the temperature control valve to pipelines with different flow requirements can be improved, enabling it to provide the most accurate flow adjustment effect possible in pipelines with different flow requirements.
