[0023] During ship manufacturing and subsequent maintenance, due to the complex pipeline layout in the bottom layer of the flower plate area, some butterfly valves are often located deeper below the flower plate. At present, the valve body located deep in the flower plate is generally driven by using an extended valve stem. However, for some unconventional valves, it is difficult to drive them by extending the valve stem, and manual processing is still required, causing great inconvenience.

[0024] With respect to the above-mentioned related technologies, the inventor believes that it is difficult to operate the valve body located at a deeper position in the bottom layer of the flower steel plate by using a conventional extended valve stem.

[0025] In order to facilitate the operation of a valve body located deep inside, the present application provides an extended butterfly valve operating handwheel device.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The present application embodiment discloses an extended butterfly valve operating hand wheel device. Figure 1-Figure 3 An extended butterfly valve operating hand wheel device includes an extension part 1, which is a rigid structure with a retractable length. After the extension is extended to determine the length, it can be used after the length is fixed. In some embodiments, the extension part 1 includes an extension sleeve 2 located on the outside, and the extension sleeve 2 is a cylindrical hollow tube body. An extension rod 3 is coaxially arranged inside the extension sleeve 2. The extension rod 3 is located inside the extension sleeve 2 and is relatively slidably connected. The outer wall of the extension rod 3 abuts against the inner wall of the extension sleeve 2. When the extension rod 3 slides into place on the inner wall of the extension sleeve 2, the overall length of the extension part 1 meets the requirements. The overall length of the extension part 1 is determined by relatively welding and fixing the extension rod 3 and the extension outer tube.

[0030] In some embodiments, a slideway is provided on the inner side wall of the extension sleeve 2, and the slideway is arranged along the circumferential direction of the extension sleeve 2, and a slider is fixedly connected to the position of the extension rod 3 relative to the slideway, and the slider is located inside the slideway and is relatively slidably connected. When the extension rod 3 slides inside the extension sleeve 2, the slider moves inside the slideway, thereby limiting the movement of the extension rod 3.

[0031] The two ends of the slideway are spaced apart from the two ends of the extended slideway, so that the extended rod 3 will not be separated from the inside of the slideway, thereby reducing the situation where the extended rod 3 is separated from the inside of the extended sleeve 2.

[0032] The extension part 1 includes a connecting end 12 close to the valve member and a driving end 11 away from the valve member. The connecting end 12 is used to be fixedly connected to the valve member, and the driving end 11 is used to manually drive the extension part 1 to rotate, thereby driving the connecting end 12 to rotate synchronously, and the valve member is driven to rotate through the connecting end 12 to realize the driving of the valve member.

[0033] In some embodiments, pin holes 13 are respectively provided at both ends of the extension part 1, and the connecting end 12 of the extension part 1 is connected to the valve member through the pin holes 13, and then the pin is inserted into the inside of the pin hole 13 to fix the valve member relative to the connecting end 12. The driving end 11 of the extension part 1 is connected to the driving hand wheel 4 through the pin hole 13, and the driving hand wheel 4 and the driving end 11 are fixed by inserting the pin into the inside of the pin hole 13, so that the extension part 1 is driven to rotate by rotating the driving hand wheel 4.

[0034] The driving hand wheel 4 includes a circular driving portion 41 and a central portion 42 located in the center. The central portion 42 is sleeved on the outside of the extension rod 3. A plurality of connecting portions 43 are fixedly connected to the driving portion 41. The connecting portions 43 are fixedly connected to the central portion 42. The plurality of connecting portions 43 are distributed on the driving portion 41 in a centrally symmetrical structure.

[0035] Reference Figure 4 A connection cap 5 is also provided at the connection end 12 of the extension part 1. In some embodiments, the connection cap 5 and the connection end 12 are detachably connected, and a threaded connection can be selected. A connection hole is provided at the end of the connection cap 5 away from the extension rod 3. The connection hole is used to match the valve component, and then the connection cap 5 is connected to the valve component. The connection cap 5 with different connection holes can be selected according to different valve components, thereby increasing the applicability of the device.

[0036] A binding section 6 is also provided on the outer side wall of the extension part 1 . The outer side wall of the binding section 6 is a frosted surface. The binding section 6 is used to connect with an external pipe support, thereby improving the connection stability of the extension part 1 .
