[0030] Example

[0031] See also Figure 1-Figure 3 The multifunctional crank for an orifice valve provided in this embodiment includes a crank body 1, a first square sleeve 2, a second square sleeve 3 and a hand-held rocker 4. The crank body 1 is, for example, a bar-shaped body, one end of which forms a first mounting end 11, and the other end forms a second mounting end 12. The first mounting end 11 and the second mounting end 12 are mainly used as a platform for mounting other workpieces; specifically, the first square sleeve 2 is welded to the first mounting end 11, and the second square sleeve 3 is welded to the second mounting end 12, which means that the first square sleeve 2 and the second square sleeve 3 are respectively located at the two ends of the crank body 1, so as to facilitate the operation of different components of the orifice valve (switch slide valve, operating lifting shaft). In order to facilitate the hand-cranking force, the hand-held rocker 4 is welded to the first mounting end 11 or the second mounting end 12, that is, the hand-held rocker 4 is located at either end of the crank body 1, so as to form a rocker arm with the longest torque with the square sleeve at the other end. The handheld rocker 4 is formed with an inner hexagonal wrench 5 at one end away from the corresponding square sleeve, so that the orifice valve can be vented and the top screw can be removed. Since the inner hexagonal wrench 5 is at the other end of the handheld rocker 4, no movement interference will occur.

[0032] Through the above technical scheme, by integrating the first square socket 2, the second square socket 3 and the hexagonal wrench 5 on the crank handle body 1, and utilizing the force application method of the crank handle body 1, not only can the sliding valve be switched, the lifting shaft be operated, the venting and the top screw be removed, but the operation is also convenient and labor-saving.

[0033] In order to cope with the high-level orifice valve in the designated station, the diameter of the first square sleeve 2 is 12mm, and the diameter of the second square sleeve 3 is 18mm, that is, the high-level orifice valve is operated using the first square sleeve 2 with 12mm and the second square sleeve 3 with 18mm.

[0034] In some embodiments, the end face of the first square sleeve 2 is welded to the side surface of the first mounting end 11; the side wall surface of the second square sleeve 3 is welded to the end of the second mounting end 12, that is, the small-diameter square sleeve is welded to the first mounting end 11 by end face welding, leaving one end face (with a square hole) for operation; the large-diameter square sleeve is welded to the second mounting end 12 by side face welding, thereby leaving two end faces (with square holes) for special operations.

[0035] On the basis of the above scheme, the hand-held rocker 4 is welded to the first mounting end 11, so that it can be used as the force-applying rocker end and rotated with the second square sleeve 3 as the axis to achieve rocker operation centered on the large-diameter square sleeve operation point, and the axial direction of the hand-held rocker 4 is parallel or consistent with the axial direction of the first square sleeve 11. When the rocker operation is centered on the small-diameter square sleeve operation point, one hand rotates the second square sleeve 3 and the other hand holds the hand-held rocker 4 for auxiliary positioning, thereby increasing the stability and smoothness of the operation. In addition, the length direction of the rocker body 1 is perpendicular to the axial direction of the hand-held rocker 4, making the rocker as a whole more convenient for force-applying operation. On this basis, the axial direction of the second square sleeve 3 is parallel or consistent with the axial direction of the hand-held rocker 4. Whether it is centered on the large-diameter square sleeve operation point or the small-diameter square sleeve operation point, this mutually perpendicular connection form can achieve a convenient and labor-saving effect.

[0036] In order to facilitate the handheld joystick 4 as a crank end to conveniently apply force to the first square socket 2 and the second square socket 3, the first square socket 2 and the second square socket 3 are located on the same side of the crank body 1. By holding the handheld joystick 4, the above operations can be performed on the first square socket 2 and the second square socket 3. In some real-time scenarios, the second square socket 3 can also be held in the hand, and the hex wrench 5 can be conveniently operated with the handheld joystick 4 as the operation center.

[0037] Considering that when the large-diameter square sleeve operation position or the small-diameter square sleeve operation position is taken as the center, there will be no motion interference between the two, especially when the second square sleeve 3 is taken as the operation center, the rotation of the hand-held rocker 4 and the first square sleeve 2 cannot affect the rotation of the second square sleeve 3. A clearance platform 6 is formed between the second square sleeve 3 and the second mounting end 12, and the clearance platform 6 makes the end face of the second square sleeve 3 away from the crank handle body 1 protrude relative to the end face of the first square sleeve 2 away from the crank handle body 1, that is, the end face of the second square sleeve 3 protrudes relatively, so that the above-mentioned motion interference will not occur (when the first square sleeve 2 is not the operation center, the rotation range of the second square sleeve 3 will not cause motion interference to the surface of the orifice valve, and when the second square sleeve 2 is not the operation center, the rotation range of the first square sleeve 2 will cause motion interference to the surface of the orifice valve).

[0038] In this embodiment, the yield platform 6 includes an inclined portion 61 and a first connecting portion 62 and a second connecting portion 63 formed at both ends of the inclined portion 61. The first connecting portion 62 is used for a smooth transition between one end of the inclined portion 61 and the second mounting end 12, and the second connecting portion 62 is used for a smooth transition between the other end of the inclined portion 61 and the side wall of the second square sleeve 3, thereby ensuring that the connection between the two sides of the yield platform 6 can form a higher strength connection form. On this basis, the thickness of the inclined portion 61 gradually increases from the second connecting portion 63 to the first connecting portion 62, thereby ensuring that the second square sleeve 2 will not be easily deformed when used as an operation center or a crank end.

[0039] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the utility model omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the utility model.
