Description

Technical Field

[0001] The utility model relates to the technical field of valve openers, in particular to a foldable modular valve opener. Background Art

[0002] Valves are devices used to control the direction, pressure, and flow of fluids in fluid systems. They enable or stop the flow of media (liquids, gases, powders) within piping and equipment, and can control their flow. Valves are control components in pipeline fluid transportation systems, used to change the cross-section of the passage and the direction of the medium's flow. They perform functions such as diverting, shutting off, throttling, checking, diverting, or providing overflow and pressure relief. On existing ships, valves in some equipment and related pipelines are often installed in confined spaces that are difficult to access. In these situations, valve openers are required to open and close the valves.

[0003] The existing valve opener is usually composed of a handle, a connecting rod and a handwheel clamp. When the handwheel clamp is clamped to the handwheel, the handle is turned to make the clamp drive the handwheel to rotate. The common valve opener is welded as a whole, which takes up a lot of space. It is inconvenient to store and transport it, which makes the valve opener less convenient to use. For this reason, we propose a foldable modular valve opener. Utility Model Content

[0007] A locking member is arranged at the bottom of the fixed disk, a baffle and a protective shell are provided at the bottom of the locking member, a rotating plate and a telescopic column are provided inside the protective shell, a side wall of the rotating plate is provided with a snap-in groove that cooperates with the telescopic column, and the telescopic column is electrically connected to a control switch.

[0008] Preferably, a plurality of locking bolts are provided on the two side walls of the folding rod.

[0009] Preferably, a threaded hole is provided on the side wall of the insertion block.

[0010] Preferably, a tension spring is provided on the side wall of the rotating plate.

[0011] Preferably, a rotating column is fixedly connected to the side wall of the rotating plate.

[0012] Preferably, the rotating column passes through the outer wall of the protective shell.

[0013] Preferably, the control switch is arranged on the top of the handle.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model can loosen the locking bolt to allow the folding rod 1 and the folding rod 2 to be pulled apart in cooperation with the limit plate, and then the folding rod 2 is rotated toward the bottom direction of the folding rod 1, and the handle of the folding rod 2 is clamped between the limit strips of the fixed plate, thereby realizing the folding of the modular valve opener, making it convenient to fold the modular valve opener for storage and transportation, and increasing the convenience of using the modular valve opener.

[0016] 2. The utility model provides a rotatable rotating plate. When the handwheel rod inside the handwheel of the valve presses against the rotating plate and enters the interior of the locking piece, the rotating plate first rotates upward and then resets, and then the telescopic column extends to cooperate with the clamping groove of the rotating plate. At this time, the rotating plate is blocked and cannot rotate to achieve the locking of the handwheel rod. When the telescopic column retracts, the rotating plate is no longer blocked and the handle can be pulled to make the locking piece move away from the handwheel rod, so that the modular valve opener can be conveniently locked with the handwheel when opening the valve, so that the valve opener and the handwheel can be stably connected when the valve opener is rotated.

[0033] In addition, the electrical components and electrical equipment mentioned above all use external power supplies. The circuits, electronic components, and modules involved in this utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to the internal structure and methods.

[0034] Working principle: After loosening the locking bolt 123, the folding rod 110 and the folding rod 2 112 can be pulled apart in cooperation with the limiting piece 121, and then the folding rod 2 112 is rotated toward the bottom direction of the folding rod 110, and the handle 113 of the folding rod 2 112 is clamped between the limiting strips 131 of the fixing piece 130, thereby realizing the folding of the modular valve opener, making it easy to fold the modular valve opener for storage and transportation, and increasing the convenience of using the modular valve opener; by setting a rotatable rotating plate 220, when the hand wheel inside the valve is When the handwheel rod presses against the rotating plate 220 and enters the interior of the locking piece 200, the rotating plate 220 first rotates upward and then resets, and then the telescopic column 210 extends to cooperate with the clamping groove 222 of the rotating plate 220. At this time, the rotating plate 220 is blocked and cannot rotate to achieve the locking of the handwheel rod. When the telescopic column 210 retracts, the rotating plate 220 is no longer blocked and the handle 113 can be pulled to make the locking piece 200 away from the handwheel rod, so that the modular valve opener can be conveniently locked with the handwheel when opening the valve, so that the valve opener and the handwheel can be stably connected when the valve opener is rotated.
