Description

Technical Field

[0001] This utility model relates to the field of fluid control equipment technology, and in particular to a ball valve opening and closing device. Background Technology

[0002] A ball valve is a rotary valve that uses a spherical valve core with a central orifice to control fluid flow. By rotating the ball 90 degrees, the fluid can be fully opened or fully closed.

[0003] Patent CN221145484U discloses a universal ball valve opening and closing device. This device opens and closes the ball valve through threaded connection when the ball valve is not in operation, effectively improving the ease of use of the ball valve. However, since the ball valve is exposed to the outside for a long time, the external threads may strip due to external factors during long-term use. This may cause inconvenience for operators when using the ball valve opening and closing device. Therefore, this problem needs to be optimized and improved. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0016] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0017] Example 1: like Figure 1-3 As shown, the ball valve opening and closing device includes a ball valve body 1 and a ball valve opening and closing device 3. The upper end of the ball valve body 1 is provided with an opening and closing base 2. The opening and closing base 2 is connected to the ball valve opening and closing device 3 to realize the opening and closing of the ball valve. The top of the ball valve opening and closing device 3 is provided with an operating rod 5. The opening and closing action of the ball valve opening and closing device 3 is controlled by rotating the operating rod 5.

[0018] The ball valve opener / closer component 3 includes a first fixing block 101, a second fixing block 104, and a rotating shaft 102. The first fixing block 101 is located directly above the second fixing block 104, and the two are fixedly connected by the rotating shaft 102. The bottom of the second fixing block 104 is provided with two magnetic fixing components 105, which are engaged with the opening / closing base 2. At the same time, a coupling 103 is coaxially provided on the rotating shaft 102 to enhance the axial stability of the rotating shaft 102.

[0019] The magnetic fixing assembly 105 includes a connecting block 201, a telescopic rod 202, a magnetic ring 203, and a matching buckle 204; the connecting block 201 is fixed to the bottom of the second fixing block 104, the upper end of the telescopic rod 202 is connected to the connecting block 201, and the lower end is connected to the magnetic ring 203, and the matching buckle 204 is provided at the bottom of the magnetic ring 203.

[0020] The installation and operation procedure for this ball valve opener / closer is as follows: The opening and closing base 2 is welded to the upper end of the DN50 ball valve body 1, and two cylindrical grooves are machined on the surface of the base; the connecting block 201 of the magnetic fixing component 105 is bolted to the bottom of the second fixing block 104, and the telescopic rod 202 has a built-in 304 stainless steel helical spring; the rotating shaft 102 passes through the first fixing block 101 and the second fixing block 104, and is axially positioned by the coupling 103; the operating rod 5 is inserted into the top of the opening and closing component 3, and its bottom is provided with a limiting boss to fix the operating rod and prevent it from falling off, while also having an interference fit with the sealing ring 4.

[0021] During use, the operator activates the magnetic ring 203, aligning the locking buckle 204 with the groove in the opening / closing base 2. The magnetic force drives the locking buckle 204 to engage in the groove, compressing and buffering the telescopic rod 202, producing a "click" sound to indicate that the locking is complete. The operator then rotates the operating lever 590° clockwise, causing the rotating shaft 102 to rotate, thus achieving full opening and full closing of the ball valve. The coupling 103 suppresses shaft misalignment, and the sealing ring 4 prevents media leakage along the operating lever.

[0022] Meanwhile, the upper surface of the opening and closing base 2 is provided with a groove, and the mating buckle 204 matches and engages with the groove. The groove and the mating buckle 204 are shaped like a strip, a triangle, or a cylinder. The strip, triangle, or cylindrical structure facilitates better engagement between the groove of the opening and closing base 2 and the mating buckle 204, making the opening and closing of the ball valve smoother and less slipping when the ball valve is rotated.

[0023] Example 2: like Figure 1-3 As shown, for high-frequency vibration scenarios in oil pipelines, the following upgrades are made to the structure of the device: the coupling 103 is replaced with a rubber-metal composite bushing, increasing the damping coefficient to 0.3; the magnetic ring 203 is equipped with a current adjustment module for stepless voltage regulation from 0 to 24V, and the adsorption force is automatically increased to 300N when the vibration intensifies; the telescopic rod 202 has a built-in disc spring assembly to buffer axial impact.

[0024] At the same time, the dynamic control function of the ball valve opening and closing device is improved. When installing, the buckle 204 is selected with a triangular configuration to resist the torsional load of the pipeline. At the same time, a sensor is set to monitor the vibration frequency in real time. When it is >50Hz, the voltage of the magnetic ring 203 is increased to 18V.

[0025] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0026] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0027] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
