Description

Technical Field

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

[0002] Currently, industrial gas temperature control valves mainly adopt the following two technical solutions: 1. Mechanical regulating valve: controls the flow of hot and cold gas through the displacement of a single valve core; 2. Electronic proportional valve: relies on external sensors and control systems.

[0003] Chinese Patent Publication No. CN217030052U discloses an intelligent temperature control valve, including a housing. The housing contains a mixing chamber, with a cold water inlet pipe at one end and a hot water inlet pipe at the other end. The inlet end of the cold water inlet pipe is located outside the housing, and a first temperature sensor and a first flow control valve are sequentially arranged along the water flow direction on the cold water inlet pipe. The inlet end of the hot water inlet pipe is also located outside the housing, and a second temperature sensor and a second flow control valve are sequentially arranged along the water flow direction on the hot water inlet pipe. This invention can mix cold and hot water in a specific ratio according to their temperatures, thereby accurately and quickly adjusting the outlet water temperature, ensuring comfort, and providing good performance.

[0004] While this device can precisely regulate water temperature by mixing hot and cold water in a specific ratio, industry technical analysis reveals the following core drawbacks: it requires simultaneous connection of both hot and cold water pipelines and ensures accurate sensor positioning, making installation significantly more difficult than with mechanical valves. Furthermore, the hot and cold water are prone to temperature stratification due to laminar flow, affecting the stability of the outlet water temperature. To address these shortcomings, we propose an industrial gas temperature control valve. Utility Model Content

The temperature control mechanism includes a medium channel disposed on the inner wall of the valve body, a first medium intercepting cylinder slidably connected to the inner wall of the medium channel, a retaining ring fixedly installed at the lower end of the valve cover, a second medium intercepting cylinder slidably connected to the inner wall of the valve cover, and multiple medium flow channel holes arranged in a circumferential array on the surface of the second medium intercepting cylinder. The lower end of the second medium intercepting cylinder is fixedly connected to the upper end of the first medium intercepting cylinder, and the lower end of the valve stem is rotatably connected to the upper end of the second medium intercepting cylinder. The gas mixing mechanism includes a mixing cylinder fixedly installed on the inner wall of the exhaust pipe, and a spiral blade fixedly installed on the inner wall of the mixing cylinder, with the upper end of the mixing cylinder extending into the interior of the first medium intercepting cylinder.

[0021] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an industrial gas temperature control valve.

[0022] like Figure 1-3 As shown, the present invention discloses an industrial gas temperature control valve, comprising a valve body 10, a valve cover 20 fixedly installed on the upper end of the valve body 10, a valve stem 30 disposed inside the valve cover 20, a cold air inlet 11 and a hot air inlet 12 respectively provided at both ends of the valve body 10, an exhaust pipe 13 provided at the lower end of the valve body 10 for gas input and output, and a temperature control adjustment mechanism and a gas mixing mechanism respectively provided inside the valve body 10.

[0023] The temperature control mechanism includes a medium channel disposed on the inner wall of the valve body 10, a first medium intercepting cylinder 40 slidably connected to the inner wall of the medium channel, a retaining ring 41 fixedly installed at the lower end of the valve cover 20, a second medium intercepting cylinder 42 slidably connected to the inner wall of the valve cover 20, and a plurality of medium flow channel holes 43 arranged in a circumferential array on the surface of the second medium intercepting cylinder 42. The first medium intercepting cylinder 40 and the second medium intercepting cylinder 42 are interconnected. The lower end of the second medium intercepting cylinder 42 is fixedly connected to the upper end of the first medium intercepting cylinder 40. The lower end of the valve stem 30 is rotatably connected to the upper end of the second medium intercepting cylinder 42. By rotating the valve stem 30, the second medium intercepting cylinder 42 is driven to move axially, thereby driving the first medium intercepting cylinder 40 to move synchronously.

[0024] A first sealing ring 70 is provided between the valve cover 20 and the second medium intercepting cylinder 42. A first gas channel 60 is formed between the first medium intercepting cylinder 40 and the medium channel. A second sealing ring 71 is provided between the medium channel and the first medium intercepting cylinder 40. A second gas channel 61 is formed between the first medium intercepting cylinder 40 and the retaining ring 41. The cross-sectional areas of the first gas channel 60 and the second gas channel 61 change inversely proportionally. When the first medium intercepting cylinder 40 moves downward, the cross-sectional area of ​​the first gas channel 60 decreases and the cold air flow rate decreases, while the cross-sectional area of ​​the second gas channel 61 increases. When the first medium intercepting cylinder 40 moves upward, the cross-sectional area of ​​the first gas channel 60 increases and the cross-sectional area of ​​the second gas channel 61 decreases, thereby realizing reverse regulation of cold / hot air flow rate and stepless control of flow ratio.

[0025] The gas mixing mechanism includes a mixing cylinder 50 fixedly installed on the inner wall of the exhaust pipe 13, and a spiral blade 51 fixedly installed on the inner wall of the mixing cylinder 50. The upper end of the mixing cylinder 50 extends into the interior of the first medium intercepting cylinder 40 to directly receive the regulated hot and cold air. After being regulated by the first medium intercepting cylinder 40, the hot and cold air enters the mixing cylinder 50. At this time, the spiral blade 51 can spin and break the airflow, destroy the laminar boundary layer, and force turbulent mixing to make the temperature uniform.

[0026] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
