Description

Technical Field

[0001] The utility model relates to the technical field of valve body anti-dropping, in particular to an anti-dropping type valve body structure. Background Art

[0002] The opening and closing parts of the ball valve are driven by the valve stem and rotate around the axis of the ball valve. They can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between the V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium in the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the drive mode.

[0003] For example, the patent document with the announcement number CN 117967852 A discloses an anti-slip valve body structure, including a valve body, a docking sleeve, a screw-on sleeve, a sealing ring body, and an anti-slip mechanism. After the docking sleeve is screwed onto the end of the valve body through the screw-on sleeve, the floating rotary rod drives the lifting cylinder to move downward, so that the lifting cylinder drives the two moving rods to move downward, so that the moving rod drives the buckle block at the outer end to pass through the floating cavity to the lower inner part of the annular buckle groove, and then the horizontal rotary rod drives the buckle block to move and press against the lower inner side of the limiting ring convex, so that the limiting ring convex is pressed inward by the pressing of the buckle block, so that the screw-on sleeve is limited by the buckle block, and when the screw-on sleeve is loosely rotated outward, the buckle block is pressed against the limiting ring convex to achieve anti-slip, so that the screw-on sleeve will not be loosely rotated outward, thereby improving the stability of the entire structure.

[0004] However, in actual use, this structure can often only check and limit the outer side of the simple valve core ball at the bottom, but the reinforcement force of the ball itself is relatively small. Once the force of the fluid entering the valve body is too large, the limiting force on the outside cannot effectively ensure that the valve body is prevented from falling off. At the same time, the valve body adopts an integrated structural design, and the internal structure cannot be quickly disassembled and maintained, which cannot meet daily use needs. Therefore, it is urgent to design an anti-falling valve body structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-slip valve body structure to solve the problem that the existing structure proposed in the above background technology can only perform a simple inspection and limit on the outer side of the valve core ball at the bottom during actual use, but the reinforcement force of the ball itself is relatively small. Once the force of the fluid entering the valve body is too large, the limiting force on the outer side cannot effectively ensure the anti-slip operation of the valve body. At the same time, the valve body adopts an integrated structural design, and the internal structure cannot be quickly disassembled, assembled, and maintained, and the daily use needs cannot be met.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-drop-off valve body structure, comprising a central valve seat, a valve stem is arranged on the top of the central valve seat, a valve core is arranged at the inner center of the central valve seat, storage racks are fixedly connected to both sides of the central valve seat, and a hydraulic rod is arranged at one end of the storage rack;

[0007] An arc frame, wherein the bottom end of the side surface of the central valve seat is fixedly connected with the arc frame, the bottom end of the arc frame is fixedly connected with a base, and a rotating disk is arranged inside the base.

[0008] Preferably, one end of the rotating disk is fixedly connected to a threaded rod, and one end of the threaded rod is provided with a bearing seat.

[0009] Preferably, one end of the threaded rod is movably connected to an oil pushing seat via a bearing seat, and an oil delivery pipe is provided at the center of each side of the arc frame.

[0010] Preferably, plug-in holes are provided at the four inner corners of the central valve seat, an inner core sleeve is provided on the inner wall of the central valve seat, and reinforced sockets are provided on both sides of the valve core through a storage rack and a hydraulic rod.

[0011] Preferably, a first connecting pipe seat is arranged on the front side of the central valve seat, and a second connecting pipe seat is arranged on the back side of the central valve seat.

[0012] Preferably, threaded bolts are provided at the four front corners of the first connecting pipe seat, and threaded caps are provided at the four back corners of the second connecting pipe seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The anti-drop-off valve body structure, through the central valve seat, valve stem, valve core, storage rack, hydraulic rod, arc frame, rotating disk, threaded rod, bearing seat, oil push seat, oil pipeline and reinforced socket, can enable the equipment to perform high-strength anti-drop-off reinforcement operation on the valve body spherical center position. In the actual use process, the staff first takes over the two ends of the central valve seat, and then rotates the valve stem on the top of the central valve seat to adjust the rotation of the central valve core inside the central valve seat to realize the regulation and control operation of the pipeline fluid at both ends. At the same time, when the central valve is used in daily life When the inside of the seat is sealed and closed by the valve core, the rotating disk inside the base can be rotated to drive the oil push seat to be lifted up inside the arc frame through the threaded rod and the bearing seat, and the hydraulic oil inside the sunken arc frame is sent along the oil pipeline to the hydraulic rods on both sides of the storage frame, so that the hydraulic rods drive the reinforced sockets contracted inside the storage frame to connect the two ends to the flow ports on both sides of the valve core, and then reinforce the valve core on both sides to ensure that the valve core performs highly stable anti-dropping operation inside the central valve seat, which reflects the practicality of the equipment design.

[0015] The anti-drop valve body structure further improves the overall use effect of the equipment by providing a central valve seat, arc frame, base, plug-in hole, inner core sleeve, first connecting pipe seat, second connecting pipe seat, threaded bolt and threaded cap. In daily use, the staff can respectively connect the first connecting pipe seat and the second connecting pipe seat at the front and rear ends of the central valve seat, and then insert the threaded bolt into the four corners of the first connecting pipe seat, and plug it into the second connecting pipe seat along the plug-in holes at the four corners inside the central valve seat, and then fix one end of the threaded bolt through the threaded cap, so as to realize the fastening and sealing installation of the two ends of the central valve seat, and facilitate the rapid disassembly and maintenance of the valve core inside the central valve seat, as well as the cleaning operation when the inner core sleeve is blocked, which reflects the comprehensiveness of the equipment design.
