Description

Technical Field

[0001] The utility model relates to the field of natural gas valves, in particular to a natural gas valve with an anti-mistouch function. Background Art

[0002] The natural gas valve is a safety device for gas pipeline projects, which is used to cut off, connect and adjust the gas in the pipeline. It has good control characteristics and closing and sealing performance, and is suitable for various gas medium pipelines such as city gas, liquefied petroleum gas, natural gas, oxygen, etc. The natural gas valve solves the problems of valve not closing tightly and not opening due to gas coking with its unique design, novel structure and good sealing performance, and effectively improves the sealing performance and service life.

[0003] In daily life, since natural gas valves are usually installed in kitchens or other easily accessible places, family members or visitors may accidentally touch them, especially when the space is narrow or there are other obstacles. For example, if there are seasonings around the natural gas valve, the natural gas valve may be accidentally touched while taking the seasonings. In addition, if the user is not familiar with the operation of the natural gas valve or is distracted during operation, it may also cause accidental touching. Therefore, when designing the natural gas valve, it is necessary to provide a new type of natural gas valve with anti-accidental touching function to further improve the overall safety. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a natural gas valve with an anti-accidental touch function to solve the technical problem of potential safety hazards in traditional natural gas valves.

[0005] To achieve the above object, the utility model provides the following technical solutions: a natural gas valve with an anti-mistouch function, comprising a valve body, a regulating mechanism is arranged on the top of the valve body, the regulating mechanism comprises a valve head, a valve core rotating rod is arranged inside the valve head, and a slot is opened on the top of the valve core rotating rod;

[0006] The top of the slot is provided with an anti-accidental touch mechanism, the anti-accidental touch mechanism comprises a rotating slot, a rotating block is rotatably connected inside the rotating slot, and a handle is fixedly connected to the top of the rotating block;

[0007] A spring groove is provided inside the handle, a movable rod passes through the axis of the spring groove, the movable rod passes through the top and bottom of the handle and is slidably connected to the handle, a lower pressure plate is fixedly connected to the outer side of the movable rod, a spring is provided inside the spring groove, and the spring abuts against the lower pressure plate.

[0008] By adopting the above technical solution, the valve body, as the basic structure of the entire valve, provides stable support and connection points to ensure the stability of the valve during use. In addition, the adjustment mechanism enables users to easily adjust the opening and closing degree of the valve through the setting of the valve head and the valve core rotating rod to meet different usage requirements.

[0009] Furthermore, an insert block is provided at the bottom of the movable rod, and the insert block is plugged into the slot.

[0010] By adopting the above technical solution, the plug-in method of the plug-in block at the bottom of the movable rod and the slot ensures a reliable connection between the anti-accidental touch mechanism and the adjustment mechanism to prevent accidental falling off or loosening. In addition, the plug-in design allows the anti-accidental touch mechanism to be quickly removed from the adjustment mechanism when necessary, which is convenient for maintenance and replacement.

[0011] Furthermore, the insert block and the slot are both arranged in a hexagonal structure, and the material of the insert block and the slot is carbon steel.

[0012] By adopting the above technical solution, the hexagonal structure increases the contact area between the plug and the slot, improves the stability of the connection, and the carbon steel material has good strength and wear resistance, which extends the service life of the plug and the slot.

[0013] Furthermore, a button is arranged on the top of the movable rod, and a card is arranged on one side of the button.

[0014] By adopting the above technical solution, the setting of the button allows the user to easily control the up and down sliding of the movable rod by pressing, and the operation is simple and intuitive. In addition, the presence of the card provides an additional safety guarantee to prevent the movable rod from sliding uncontrollably, thereby enhancing the anti-accidental touch function.

[0015] Furthermore, a card slot is provided on the top of the handle, and the card slot is engaged with a card.

[0016] By adopting the above technical solution, the card slot and the card are connected in a way that ensures the stability of the handle during the adjustment process, preventing misoperation caused by accidental touch, and the card connection design allows the handle to be quickly separated from other parts of the anti-mistouch mechanism when needed.

[0017] Furthermore, the card and the card slot are used to ensure that the handle drives the slot to rotate through the insertion block.

[0018] By adopting the above technical solution, through the coordinated use of the card and the card slot, it is ensured that the handle can accurately drive the slot and the valve core rotating rod to rotate when it is turned, thereby improving the accuracy of adjustment. In addition, this design method also enhances the structural strength of the entire anti-mistouch mechanism and improves its ability to withstand external forces.

[0019] Furthermore, an air inlet and an air outlet are respectively provided on two sides of the valve body, and the air inlet and the air outlet are interconnected.

[0020] By adopting the above technical solution, the through-connection design of the air inlet and the air outlet enables natural gas to pass through the valve smoothly, reducing flow resistance and improving the flow efficiency of the valve. In addition, the design of the two ports also facilitates connection with external natural gas pipelines and simplifies the installation process.

[0021] Furthermore, both ends of the air inlet and the air outlet are fixedly connected to external natural gas pipelines respectively, and the entire material of the valve body is stainless steel.

[0022] By adopting the above technical solution, the stainless steel material has good corrosion resistance and strength, and can resist the corrosive components in natural gas and the influence of the external environment, thereby extending the service life of the valve. Moreover, the fixed connection method with the external pipeline ensures that the valve will not be displaced or fall off due to external force during use, thereby improving the safety of the entire system.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] 1. The utility model is provided with an anti-mistaken touch mechanism. Since a card slot is provided on the top of the handle, the card slot is engaged with the card. Therefore, when the button is pressed, the card will be inserted into the card slot, so that the movable rod can slide downward, and the plug at the bottom of the movable rod will be inserted into the slot of the valve core rotating rod. At this time, the switch of the valve can be adjusted by turning the handle. When the button is released, due to the elastic force of the spring, the movable rod will slide upward, and the plug will be pulled out of the slot. At this time, the valve is in an anti-mistaken touch state and cannot be adjusted at will.

[0025] 2. The utility model provides an adjustment mechanism, an insert block, and a slot, wherein the insert block and the slot are all hexagonal structures. Therefore, compared with a circular or square structure, the edge of the hexagonal structure is more prominent and unique, so it can provide greater friction and stability when plugged in, which means that when turning the handle to adjust the valve, the insert block is less likely to slide or misalign in the slot, ensuring the accuracy and reliability of the operation. Moreover, since the hexagon has more sides than the quadrilateral, when it is subjected to torque, each side shares less force, so that a greater torque can be transmitted without being easily damaged. This makes the connection between the insert block and the slot more stable and less likely to break or fail when the valve needs to be rotated vigorously, such as when it is closed or opened in an emergency.

[0035] See also Figure 1 , Figure 2 , Figure 3 A plug block 508 is provided at the bottom of the movable rod 506, and the plug block 508 is plugged into the slot 403. The plug block 508 and the slot 403 adopt a hexagonal structure to ensure that the connection between the two is tight and not easy to loosen, and the torque can be stably transmitted during the valve switching process. Moreover, the hexagonal design allows the user to intuitively perceive the alignment of the plug block 508 and the slot 403 during operation, which is convenient for completing the plug-in action quickly and accurately.

[0036] See also Figure 2 , Figure 3 , Figure 4 The plug block 508 and the slot 403 are both arranged in a hexagonal structure. The material of the plug block 508 and the slot 403 is carbon steel. The hexagonal structure makes it difficult for the plug block 508 and the slot 403 to be opened by conventional tools, thereby enhancing the anti-theft ability of the valve. In addition, the carbon steel material has good hardness and wear resistance, can resist friction and impact in daily use, and extend the service life of the valve.

[0037] See also Figure 1 , Figure 2 , Figure 3 A button 509 is disposed on the top of the movable rod 506, and a card 510 is disposed on one side of the button 509. The user only needs to press the button 509 and push the card 510 to easily complete the opening and closing operations of the valve without complicated steps or tools.

[0038] Embodiment 2:

[0039] See also Figure 1 , Figure 3 A card slot 511 is provided at the top of the handle 503, and the card slot 511 is engaged with the card 510. The design of the card slot 511 enables the card 510 to be accurately aligned and locked when inserted, thereby avoiding valve switching errors caused by misoperation. Moreover, the card slot 511 and the card 510 are tightly and stably engaged, and are easy for users to unlock and re-lock, which is convenient for daily use.

[0040] See also Figure 1 , Figure 2 The card 510 and the card slot 511 are used to ensure that the handle 503 drives the slot 403 to rotate through the plug block 508. The cooperation between the card 510 and the card slot 511 can ensure that the handle 503 efficiently drives the slot 403 and the valve core rotating rod 402 to rotate through the plug block 508, so as to quickly and accurately adjust the opening of the valve. Moreover, since the card 510 and the card slot 511 are closely matched and rotate smoothly, the user will not feel frustration or stagnation during operation, which improves the comfort of use.

[0041] See also Figure 1 , Figure 2 An air inlet 2 and an air outlet 3 are respectively provided on both sides of the valve body 1, and the air inlet 2 and the air outlet 3 are connected. The through-connection design of the air inlet 2 and the air outlet 3 ensures that the natural gas can pass through the valve smoothly, reducing the flow resistance and pressure loss. Moreover, the standardized design of the air inlet 2 and the air outlet 3 enables the valve to be easily connected to the external natural gas pipeline, simplifying the installation process and reducing the installation cost.

[0042] See also Figure 1 , Figure 2 , Figure 4 The two ends of the air inlet 2 and the air outlet 3 are fixedly connected to the external natural gas pipeline respectively. The overall material of the valve body 1 is stainless steel. The stainless steel material has good corrosion resistance and can resist the erosion of the valve body by impurities and moisture in the natural gas, thereby extending the service life of the valve. In addition, the stainless steel material has high strength and low weight, so that the valve can withstand pressure while maintaining its lightness, which is convenient for transportation and installation.

[0043] The implementation principle of the utility model is as follows: first, when opening the valve again, the button 509 needs to be pressed, and the button 509 drives the movable rod 506 to slide downward, compressing the spring 505. At the same time, the plug 508 is inserted from the slot 403 to ensure the connection between the plug 508 and the valve core rotating rod 402. At the same time, the card 510 will be engaged with the card slot 511. At this time, the handle 503 can drive the valve core rotating rod 402 to rotate;

[0044] When the valve needs to be in an accidental touch state, it is only necessary to rotate the handle 503 in the opposite direction to turn the valve core rotating rod 402 back to the closed position, and then release the button 509. Under the action of the spring 505, the movable rod 506 slides upward, and the plug block 508 re-disengages from the slot 403. At this time, turning the handle 503 in time will not cause the valve core rotating rod 402 to rotate, thereby achieving the effect of preventing accidental touch.

[0045] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0046] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
