Description

Technical Field

[0001] The utility model relates to the technical field of gas valves, in particular to a gas pipeline control valve. Background Art

[0002] Gas pipeline control valves are used to control the opening and closing of pipelines and are usually called regulating valves or control valves. The main function of this type of valve is to adjust the flow and pressure of the medium in the pipeline, and to control the gas flow by changing the opening and closing degree of the valve.

[0003] However, gas pipeline control valves use complex mechanical structures and precision processing technology in the design and manufacturing process. These structures and technologies ensure that the valve can accurately regulate the flow and pressure of the gas, but they also increase the manufacturing cost and complexity. In some application scenarios, users may not need such high-precision control, or cannot afford the high cost due to budget constraints. Utility Model Content

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] See also Figures 1 to 4 , is a gas pipeline control valve according to an embodiment of the present invention, comprising a valve body assembly 10 and a valve plate assembly 20 connected to the valve body assembly 10 .

[0025] The valve body assembly 10 includes a valve body 11, support sheets 12 installed on opposite sides of the inner wall of one end of the valve body 11, and a plurality of through-beam photoelectric switches 13 evenly spaced and arrayed on one side of each support sheet 12. The valve body 11 is arranged in a tubular shape and is used to be installed in the middle section of the gas pipeline. The support sheet 12 and the through-beam photoelectric switch 13 are arranged at intervals.

[0026] In this embodiment, the number of the through-beam type photoelectric switches 13 on each side of the inner wall of the valve body 11 is at least three, and the through-beam type photoelectric switches 13 are arranged in an array along the length direction of the support sheet 12 .

[0027] Furthermore, a through groove (not shown) is provided on one side of the valve body 11 close to the valve plate assembly 20 , and the through groove is used for arranging components of the valve plate assembly 20 .

[0028] The valve plate assembly 20 includes a bearing frame 21 installed on one side of the outside of the valve body 11, a lead screw 22 rotatably installed inside the bearing frame 21, a motor 23 installed at one end of the lead screw 22 away from the valve body 11, a lead screw nut 24 matched with the lead screw 22, and a valve plate 25 connected to the lead screw nut 24; one end of the valve plate 25 is used to penetrate and extend into the interior of the valve body 11, and a positioning piece 26 is connected to the end of the valve plate 25 located inside the valve body 11, and the positioning piece 26 is used to correspond to the radiation type photoelectric switch 13. In actual use, the extension amount of the valve plate 25 directly determines the opening and closing size of the inside of the valve body 11, thereby controlling the gas flow of the gas pipeline. As a key component, the radiation type photoelectric switch 13 can sense the movement of the valve plate 25 in real time and accurately, and quickly feed back this information to the control system. This feedback mechanism enables the control system to dynamically control the motor 23 to adjust the position of the valve plate 25 to achieve accurate control of the gas flow. Whether the flow needs to be increased or decreased, the control system can respond quickly and accurately based on the data provided by the photoelectric switch 13. Compared with the traditional gas pipeline control valve, the utility model adopts a simpler mechanical structure, which drives the valve plate 25 to slide inside the valve body 11 through the screw 22 to achieve opening and closing adjustment. This simplification not only reduces the manufacturing cost, but also improves the reliability and durability of the valve 11. At the same time, the use of multiple photoelectric switches 13 ensures the accuracy of valve positioning, making the control of gas flow more accurate and stable. While meeting the demand for precise control in industrial production, it also effectively controls costs, providing users with a more economical and affordable choice.

[0029] In this embodiment, if Figure 3 and Figure 4 As shown, the valve plate 25 is matched with a through groove, and the opposite sides of the valve plate 25 are clamped in the gap between the support sheet 12 and the opposing photoelectric switch 13, which can effectively limit the valve plate 25, improve the connection stability between the valve plate 25 and the valve body 11, and at the same time improve the opening and closing control accuracy of the entire control valve.

[0030] In this embodiment, the lead screw 22, the motor 23 and the lead screw nut 24 are all located outside the valve body 11, which can prevent these components from directly contacting the inside of the valve body 11, making the structure inside the valve body 11 more concise and reducing potential leakage points. At the same time, the external design also facilitates the maintenance and replacement of these components, improving the overall reliability and service life.

[0031] The above-mentioned gas pipeline control valve has a simple structure and is easy to use. It adopts a simpler mechanical structure. The valve plate 25 is driven by the screw 22 to slide through the interior of the valve body 11, and is matched with a plurality of opposing photoelectric switches 13 to position and control the opening and closing size. It effectively controls costs while meeting the needs, providing a more economical and affordable choice.

[0032] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
