Description

Technical Field

[0001] This utility model relates to the field of temperature control valve technology, and more specifically, to a flow-guided temperature control valve for engineering machinery. Background Technology

[0002] In industries such as hot water, heating, and water cooling, independent manual or automatic temperature control valves are generally used when temperature control is involved. A temperature control valve typically includes a temperature control valve controller and a regulating valve. When in use, a temperature is set through the temperature control valve controller. The temperature sensor of the indoor temperature and the thermal expansion and contraction of the temperature sensor control the opening and closing of the regulating valve to make the indoor temperature consistent with the temperature set by the temperature control valve controller, thus achieving the purpose of temperature regulation.

[0003] In actual use, when the temperature control valve outputs liquid, the liquid flow inside the valve body is blocked by the inner wall of the valve body, which causes the liquid flow to be obstructed. This makes it easy for particulate matter in the liquid to accumulate and affect the performance of the temperature control valve. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a flow-guided temperature control valve for engineering machinery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flow-guiding temperature control valve for engineering machinery includes a valve cover, a valve body on top of the valve cover, multiple bolts threadedly connecting the valve cover and the valve body, gaskets fitted around the bolts, a first connecting flange fixedly connected to the bottom of the valve cover, two second connecting flanges fixedly connected to the outside of the valve body, and a flow-guiding mechanism inside the valve body. The flow-guiding mechanism includes a first outlet and a second outlet, respectively located on opposite sides of the valve body. An arc-shaped surface is provided inside the valve body, and two sealing seats are fixedly connected thereto. The first and second outlets are symmetrically arranged inside the valve body. A valve core is installed on the valve cover and the valve body, a temperature bulb is fixedly connected to the bottom of the valve core, an O-ring is fitted around the outside of the valve core, and a lip-shaped toothed ring is fixedly connected to the top of the valve core. The O-ring is made of fluororubber. A compression sealing mechanism is provided on the outside of the first and second connecting flanges.

[0007] By adopting the above technical solution: water outlet one and water outlet two are used to guide and transport liquids with temperatures higher and lower than the temperature bulb respectively. The arc-shaped surfaces inside water outlet one and water outlet two are used to guide the liquid, improving the smoothness of the liquid flow. The O-rings made of fluororubber are used to improve corrosion resistance and high temperature resistance. In addition, the interference fit of the lip-shaped toothed ring with the internal sealing seat of the valve body improves the pressure resistance and sealing performance of the valve core and valve body connection.

[0008] As a further description of the above technical solution: the extrusion sealing mechanism includes multiple slots, the slots are disposed on one side of connecting flange one and connecting flange two, a sealing ring is fixedly connected to the inner side of the slot, a cavity is opened on the inner side of the sealing ring, and multiple reinforcing ribs are fixedly connected to the inner side of the cavity, the reinforcing ribs are distributed in a ring array inside the sealing ring.

[0009] By adopting the above technical solution, the sealing rings inside connecting flange one and connecting flange two can deform when compressed, allowing the sealing rings to fit more closely to the connecting surface and maintain the sealing performance between the temperature control valve and the external pipeline.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up a flow guiding mechanism, compared with the existing technology, the arc-shaped surfaces inside the outlet one and outlet two facilitate shot peening of the arc-shaped surfaces, and at the same time guide the liquid during the flow process, reduce dead angles in the liquid flow, avoid the throttling phenomenon of the temperature control valve, make the liquid flow smoother, and reduce the risk of impurities accumulating in the temperature control valve.

[0012] 2. By setting up a compression sealing mechanism, compared with the existing technology, the compression sealing of the groove and sealing ring can maintain the seal between the temperature control valve and the pipeline. At the same time, the elastic support of the sealing ring by the cavity can improve the sealing performance of the connection between the temperature control valve and the external connecting pipeline.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The embodiments disclosed in this application are as follows: Figure 1-6 The flow-guiding type temperature control valve for engineering machinery shown includes a valve cover 1, a valve body 2 on the top of the valve cover 1, multiple bolts 15 threadedly connected to the inner sides of the valve cover 1 and the valve body 2, and washers 16 fitted on the outer sides of the bolts 15. A connecting flange 3 is fixedly connected to the bottom of the valve cover 1, and two connecting flanges 4 are fixedly connected to the outer side of the valve body 2. A flow-guiding mechanism is provided inside the valve body 2. The flow-guiding mechanism includes an outlet 17 and an outlet 28, which are respectively located on both sides of the valve body 2. An arc-shaped surface 5 is provided inside the valve body 2, and two sealing seats 6 are fixedly connected to the inner side of the valve body 2. The outlet 17 and outlet 28 are symmetrically arranged inside the valve body 2. A valve core 7 is installed inside the valve cover 1 and the valve body 2, and the bottom end of the valve core 7 is fixedly connected to... The valve has a temperature bulb 8, an O-ring 9 fitted on the outside of the valve core 7, and a lip-shaped toothed ring 10 fixedly connected to the top of the valve core 7. The O-ring 9 is made of fluororubber. A compression sealing mechanism is provided on the outside of the connecting flange 1 3 and the connecting flange 2 4. The valve core 7 and the temperature bulb 8 are used to control the liquid with a temperature lower than the set temperature to be discharged from the outlet 2 18 side, and the liquid with a temperature higher than the set temperature to be discharged from the outlet 1 17 side. The arc-shaped surface 5 inside the outlet 1 17 and the outlet 2 18 guides the liquid during the flow process. The arc-shaped surface 5 also ensures that there are no dead corners in the shot peening process of the valve body 2, and at the same time, the liquid flows more smoothly, reducing the deposition of impurities in the temperature control valve and improving the overall reliability and service life of the valve body.

[0022] Reference Figure 1 , Figure 4 and Figure 5As shown, the compression sealing mechanism includes multiple slots 11, which are located on one side of connecting flange 3 and connecting flange 4. A sealing ring 12 is fixedly connected to the inside of the slot 11. A cavity 13 is opened inside the sealing ring 12, and multiple reinforcing ribs 14 are fixedly connected to the inside of the cavity 13. The reinforcing ribs 14 are arranged in a ring array inside the sealing ring 12. By utilizing the elastic deformation of the sealing ring 12 inside the slot 11 under compression, and in conjunction with the multiple reinforcing ribs 14 inside the sealing ring 12, the sealing ring 12 has good support force, which reduces the risk of leakage when the temperature control valve is connected to the external pipeline and improves the safety of the temperature control valve.

[0023] The working principle of this utility model is as follows: When liquid temperature is controlled, if liquid with a temperature lower than the opening temperature of the temperature sensor enters the valve cover 1, the temperature sensor 8 will not control the valve core 7 to move upward, allowing the liquid inside the valve cover 1 to enter the outlet 18 through the valve core 7. The liquid is then discharged through the outlet 18 and the connecting flange 4 on one side. Afterward, if liquid with a temperature lower than the temperature controlled by the temperature sensor enters the valve cover 1, the valve core 7 will be in the middle of the valve body 2, allowing the liquid entering the valve cover 1 to be output through the outlets 17 and 18 on both sides. Then, if liquid with a temperature higher than the fully open temperature of the temperature sensor enters the valve cover 1, the temperature sensor 8 will control the valve core 7 to move upward, allowing the O-ring 9 on the outside of the valve core 7 to separate from one side of the valve cover 1, allowing the high-temperature liquid inside the valve cover 1 to pass through... The outlet 17 outputs water, and the arc-shaped surface 5 inside the valve body 2 can guide the output liquid to reduce dead angles in the liquid flow. When assembling the valve cover 1 and valve body 2, the valve cover 1 and valve body 2 are fastened together by bolts 15 and washers 16. Then, when the temperature control valve is connected to the external pipeline, it is bolted to the pipeline by connecting flange 1 3 and connecting flange 2 4. When connecting flange 1 3 and connecting flange 2 4 are squeezed against the pipeline, the sealing ring 12 inside the connecting flange 1 3 and connecting flange 2 4 will be fully squeezed. The cavity 13 inside the sealing ring 12 allows the sealing ring 12 to be squeezed and fitted against the pipeline wall, so that the temperature control valve and the pipeline are tightly connected. Finally, the interference fit between the lip tooth ring 10 and the sealing seat 6 is used to improve the sealing pressure resistance of the valve core 7, the lip tooth ring 10 and the sealing seat 6.
