Description

Technical Field

[0001] The utility model relates to the technical field of ball valve control equipment, in particular to a ball valve handle for oil fields. Background Art

[0002] A ball valve is a valve in which the opening and closing member (ball) is driven by the valve stem and rotates around the axis of the ball valve. With the rapid development of science and technology, and the continuous improvement of production processes and product structures, ball valves have gradually developed into a major valve type. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of media.

[0003] The ball valve can be opened and closed by rotating the handle 90 degrees and applying a very small torque to close it tightly. Therefore, it is widely used in oil refining, water conservancy, electricity, municipal engineering, steel and other industries. The ball valve handles currently used in the oil field are mostly square interfaces.

[0004] During use, ball valves are often located in an environment with dense pipeline equipment, especially in oilfield conditions. The existing ball valve rotating handle is limited in length, inconvenient to operate, the handle may be blocked by other equipment, and the operation is laborious. Therefore, a new type of ball valve handle for oilfields is urgently needed. Utility Model Content

[0005] The purpose of the utility model is to provide a ball valve handle for oil fields to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ball valve handle for oil fields, comprising: a ball valve body, a valve stem, and a rotating rod, wherein the valve stem is connected to control the opening and closing of the ball valve body;

[0007] A through slot is formed on the top of the valve stem, and an external through hole group communicating with the through slot is formed on the valve stem;

[0008] The bottom end of the rotating rod is fixedly connected to an insert block matching the through slot, and the insert block is provided with an inner through hole matching the outer through hole group, and the outer through hole group and the inner through hole are matched with bolts and nuts for fixing;

[0009] The top end of the rotating rod is connected with a handle.

[0010] Preferably, a polygonal groove is provided at the top of the rotating rod, a card slot is provided at the bottom end of the polygonal groove, a polygonal hole matching the polygonal groove is provided on the handle, a matching polygonal card block is inserted into the polygonal groove and the polygonal hole, a plug-in card block is fixedly connected to the bottom end of the polygonal card block, the plug-in card block is clamped in the card slot, and a pull ring is fixedly connected to the top of the polygonal card block.

[0011] Preferably, the top surface of the polygonal block is a regular hexagon.

[0012] Preferably, the polygonal groove is provided on one side of the top end of the rotating rod close to the hand-grip end of the handle, and a buffer pad is provided on the other side of the top end of the rotating rod.

[0013] Preferably, the bottom end of the through groove is provided with an arc-shaped bottom groove, and the bottom end of the insert block is provided with an arc-shaped portion matching the arc-shaped bottom groove.

[0014] Preferably, the inserting block is provided with protrusions on both opposite sides facing outwards of the through slot.

[0015] Preferably, the handle is a Z-shaped structure.

[0016] Compared with the prior art, the present invention has at least the following technical effects or advantages:

[0017] By setting a rotating rod, a through slot, and an insert, the handle can be lifted longitudinally to rotate the handle around the axis to a suitable position, changing the angle between the handle and the rotating rod, and then twisted horizontally to avoid obstacles and twist it into place, which also makes it easier for the operator to exert force.

[0018] By providing an arc-shaped bottom groove, the arc-shaped portion rotates in the arc-shaped bottom groove. Due to the existence of friction, the angle of the handle can be stably maintained, and when rotating, shaking is reduced, reducing the possibility of not being screwed into place.

[0019] By arranging a protrusion on the plug block, the protrusion abuts against the edge of the through groove after the rotating rod rotates to a certain angle, thereby limiting the range of the longitudinal rotation angle of the rotating rod, ensuring that the handle is always within the operable angle range, and avoiding the possibility of the handle flipping over and causing the ball valve to switch malfunction.

[0020] By setting up polygonal blocks, polygonal holes and polygonal grooves, the handle is fixed horizontally. The plug-in block is connected to the slot to fix the handle vertically. The polygonal groove is set at the top of the rotating rod close to the hand-held end of the handle, which increases the force contact area between the handle and the top of the rotating rod when pulling, reduces the pressure, reduces the chance of damage to the handle, and improves durability.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings, wherein the same parts are represented by the same figure numerals. It should be noted that the words "front", "rear", "left", "right", "up" and "down", "bottom" and "top" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 As shown, the present invention provides a technical solution to solve the problem in the background art that the handle is easily obstructed, inconvenient to operate and laborious to use. Example

[0030] like Figure 1 and Figure 2 As shown, a ball valve handle for oil fields includes a ball valve body 1, a valve stem 2, and a rotating rod 3. The valve stem 2 is connected to control the opening and closing of the ball valve body 1. A through groove 21 is provided at the top of the valve stem 2, and an external through hole group 22 connected to the through groove 21 is provided on the valve stem 2. An insert block 31 matching the through groove 21 is fixedly connected to the bottom end of the rotating rod 3. An internal through hole 32 matching the external through hole group 22 is provided on the insert block 31. The external through hole group 22 and the internal through hole 32 are matched with bolts 6 and nuts 61 for fixing. The rotating rod 3 can achieve a longitudinal rotation around the bolt 6 through the restricted cooperation of the bolt 6 and the nut 61. The cooperation between the bolt 6 and the nut 61 cannot be too tight, and it is sufficient to meet the normal rotation requirements. The top of the rotating rod 3 is connected to a handle grip 4;

[0031] In actual use, when the handle 4 is blocked by other components and equipment and cannot be properly screwed into place, or the distance between them is too close, making it inconvenient for the operator to exert force, causing practical difficulties and effort, the handle 4 can be pulled vertically to rotate it around the axis to a suitable position, changing the angle between it and the rotating rod 3, and then twisted horizontally to avoid the obstruction and screw it into place, which also makes it easier for the operator to exert force;

[0032] Among them Figure 2 、 Figure 3 As shown, an arc-shaped bottom groove 211 is provided at the bottom end of the through groove 21, and an arc-shaped portion 311 matching the arc-shaped bottom groove 211 is provided at the bottom end of the insert block 31. The arc-shaped portion 311 rotates in the arc-shaped bottom groove 211. Due to the existence of friction, the adjusted angle of the handle 4 can be maintained stably, and when rotating, shaking is reduced, reducing the possibility of not being screwed into place. Example

[0033] Based on the first embodiment, Figure 3 As shown, a ball valve handle for oil fields has a polygonal groove 33 formed on the top of the rotating rod 3, a clamping groove 331 formed on the bottom end of the polygonal groove 33, a polygonal hole 41 matching the polygonal groove 33 is formed on the handle 4, a matching polygonal clamping block 5 is inserted into the polygonal groove 33 and the polygonal hole 41, a plug-in clamping block 52 is fixedly connected to the bottom end of the polygonal clamping block 5, the plug-in clamping block 52 is clamped in the clamping groove 331, a pull ring 51 is fixedly connected to the top end of the polygonal clamping block 5, the top surface of the polygonal clamping block 5 is a regular hexagon, and its matching polygonal groove 33 and polygonal hole 41 are also regular hexagons. The regular hexagon can evenly disperse stress and improve the service life of the handle device;

[0034] The polygonal clamping block 5 is disposed within the polygonal hole 41 and the polygonal groove 33, securing the handle 4 laterally. The plug-in clamping block 52 is engaged within the groove 331, securing the handle 4 longitudinally. The polygonal groove 33 is disposed at the top of the rotating rod 3, near the handheld end of the handle 4. This increases the contact area between the handle 4 and the top of the rotating rod 3 when the handle 4 is pulled, thereby reducing pressure, reducing the chance of damage to the handle 4, and improving durability. A cushion 7 is disposed on the other side of the top of the rotating rod 3 to further protect the handle 4. Furthermore, the Z-shaped structure of the handle 4 facilitates both twisting and pulling operations.
