Description

Technical Field

[0001] This utility model relates to an oil and gas pipeline tool, and more specifically, a fixed valve handwheel lifting device. Background Technology

[0002] Most valves in oil and gas gathering and transportation pipelines utilize classic handwheel valves, which are convenient to operate and inexpensive, but also have some drawbacks. Therefore, professionals have innovated and improved them. Currently, innovations in handwheel valves mainly focus on labor-saving operation, automated control, and remote operation. Labor-saving valve designs primarily utilize physical principles to modify the handwheel structure to achieve the desired effort reduction. Automated control generally uses hydraulic or pneumatic pressure to open and close the valve. Remote control typically uses sensors to control valve opening and closing. However, for valves located in concealed positions, there are no specific solutions for the opening and closing issues. For example, when pipelines are laid in underground trenches, the handwheel is positioned low and space is limited, making it difficult to apply force to open and close the valve, hindering operation. In emergencies, the inability to turn the handwheel in time to shut off the valve may lead to significant adverse consequences, even major accidents and property damage. Utility Model Content

Detailed Implementation

[0013] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0014] like Figure 1 and Figure 2 As shown, the fixed valve handwheel raising device includes an extension head 10, and a pair of opposing clamps 20 are provided below the extension head 10. The clamps 20 are detachably connected to the extension head 10.

[0015] The extension head 10 includes a tubular extension tube 11. The bottom end of the extension tube 11 is provided with an annular connecting plate 12. The lower part of the side wall of the extension tube 11 is provided with a through oblong observation slot 14. The upper part of the side wall of the extension tube 11 is provided with a through rotating through hole 13. The circumference of the connecting plate 12 is provided with a plurality of through first connecting round holes 15.

[0016] The clamp 20 includes a semi-annular main base plate 21, on which a plurality of through second connecting round holes 22 are provided. The second connecting round holes 22 are connected to the first connecting round holes 15 by connecting bolts 50.

[0017] It should be noted that the connecting plate 12 is welded to the extension tube 11.

[0018] In addition, a sealing cap 16 is provided at the top of the extension tube 11. The sealing cap 16 is welded to the extension tube 11.

[0019] The following describes the operation of the fixed valve handwheel raising device, including the steps: Step S1: Place the extension tube 11 of the extension head 10 onto the valve screw 30; Step S2: Place the two clamping plates 20 under the valve handwheel 40 to form a ring shape, so that it is basically aligned with the connecting plate 12; Step S3: Align the second connecting hole 22 on the clamping plate 20 with the first connecting hole 15 on the connecting plate 12, and use four Φ14mm connecting bolts 50 to fix the second connecting hole 22 and the first connecting hole 15 together. Thus, the clamping plate 20 and the connecting plate 12 are firmly fixed to the valve handwheel 40. At this time, the extension pipe 11 protrudes about 30cm from the ground. Step S4: By inserting the handle of an "F" wrench or a steel pipe into the rotating through hole 13, rotate the valve handwheel 40 using the lever principle. At the same time, observe the opening degree of the valve screw 30 by looking at the slot 14.

[0020] like Figure 3 and Figure 4The image shows a second embodiment of the fixed valve handwheel raising device of this utility model. A detachable extension sleeve 50 is provided above the extension head 10. A through lower hole 51 is provided on the lower part of the side wall of the extension sleeve 50, and a through upper hole 52 is provided on the upper part of the side wall of the extension sleeve 50. The lower hole 51 is connected to the rotating through hole 13 via an extension bolt 60.

[0021] It should be noted that the inner diameter of the extension sleeve 50 is adapted to the outer diameter of the extension tube body 11.

[0022] When the length of the extension tube 11 is insufficient, the extension sleeve 50 can be fixed to the head of the extension tube 11 to further improve the ease of use of the lifting device.

[0023] This device extends the valve control part to the ground and utilizes the lever principle to enable convenient and effortless turning of the valve handwheel. It also makes the valve's open / closed status visible. The part of the device that extends to the ground occupies little space, is simple to operate, and makes up for the shortcoming of handwheel valves being difficult to operate in confined spaces. It has low manufacturing costs, simple installation methods, good field application results, convenient valve opening and closing, small space occupation, safe operation, and strong practicality.
