Abstract
Description
Technical Field
[0001] The utility model relates to a valve, more specifically, to a butterfly valve. Background Art
[0002] A butterfly valve regulates fluid flow by rotating a disc-shaped disc (disc) around the valve axis. When the disc rotates 90°, the valve can be switched between fully open and fully closed. By changing the disc's angle, the flow rate of the medium can also be adjusted.
[0003] According to the manual opening and closing method, they are divided into handle butterfly valves and turbine butterfly valves. The handle butterfly valve is separated from the gear plate by pressing the handle, and then the valve core is rotated by turning the handle. When it is rotated into place, the handle is released to make the handle and the gear plate engage again to form a limit.
[0004] However, since the tooth pitch on the gear plate is arranged at equal distances, the handle and the tooth groove often cannot be aligned, requiring multiple adjustments to the position, or even the need to look down to check. Utility Model Content

[0026] Reference Figures 1 to 5 As shown, to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a butterfly valve, comprising a valve body 1, a valve stem 2 and a handle 3, wherein the valve stem 2 is rotatably connected to the valve body 1, and one end of the handle 3 is fixedly connected to the valve stem 2; a limit plate 4 is provided on the valve body 1, and a plurality of limit grooves 41 are provided on the limit plate 4, and the plurality of limit grooves 41 are arranged at equal angles A along the circumference of the limit plate 4;
[0027] A marble assembly 5 is provided on the limiting disk 4, and a limiting hole 31 is provided at one end of the handle 3. There are multiple groups of limiting holes 31 and / or marble assemblies 5, which are arranged at equal angles B along the circumference of the limiting disk 4, and angle A is the same as angle B.
[0028] The design of the utility model is combined with Figure 2 and Figure 3 As shown, when the handle 3 is separated from the limiting slot 41 and the handle 3 is rotated, the marble assembly 5 is limited by the limiting hole 31 during the rotation process, so that there will be a sense of frustration every time it is rotated by an angle, so that the operator can judge whether the handle 3 is aligned with the limiting slot 41 by feel, thereby improving the convenience of operation.
[0029] The present invention is further configured as follows: one group of limiting holes 31 is provided, multiple groups of marble assemblies 5 are provided, and the marble assemblies 5 and the limiting slots 41 are provided in a one-to-one correspondence.
[0030] When the handle 3 is rotated from one side to the other, the limiting holes 31 will respectively cooperate with each marble assembly 5. When the marble assembly 5 is inserted into the limiting hole 31 and then moved out, a sense of frustration can be formed.
[0031] The present invention is further configured as follows: a plurality of groups of limiting holes 31 are provided, and are arranged in a one-to-one correspondence with the limiting grooves 41 , and a group of marble components 5 is provided. Figure 2 and Figure 3 It is the implementation diagram of this embodiment. Similarly, when the handle 3 rotates, the ball component 5 will form a fit with each limiting hole 31 respectively, and a sense of jerk will also be formed.
[0032] The present utility model is further configured that: both the limiting holes 31 and the ball components 5 are provided with multiple groups, and they are arranged in one-to-one correspondence with the limiting grooves 41.
[0033] The present utility model is further configured that: the ball component 5 includes an installation groove 51, a limiting ball 52 and a limiting spring 53 arranged on the limiting disc 4, and the limiting ball 52 is installed in the installation groove 51 through the limiting spring 53.
[0034] With the design of this structure, when the handle 3 rotates, when the installation groove 51 corresponds to the limiting hole 31, under the action of the limiting spring 53, the limiting ball 52 is clamped into the installation groove 51, forming an obstruction.
[0035] Embodiment 1, as Figure 3 shown, a metal plate 32 is arranged in the limiting hole 31. When the limiting ball 52 is embedded into the limiting hole 31, it collides with the metal plate 32. With the design of this structure, when the limiting ball 52 is clamped into the limiting hole 31, the limiting ball 52 collides with the metal plate 32 to emit a clear sound, thereby improving the recognition during rotation.
[0036] Embodiment 2, as Figure 4 and Figure 5 shown, a visible groove 33 is arranged at the upper end of the handle 3. The visible groove 33 is communicated with the limiting hole 31, and a linkage member 6 is arranged in the visible groove 33.
[0037] The present utility model is further configured that: the linkage member 6 includes a linkage rod 61 and a linkage spring 62, and the linkage rod 61 is slidably connected in the visible groove 33 through the linkage spring 62.
[0038] As Figure 4 and Figure 5 shown, when the limiting ball 52 is clamped into the limiting hole 31, it can push the linkage rod 61 to move upward, so that the linkage rod 61 approaches the visible groove 33, which is convenient for the operator to observe from the outside.
[0039] The present utility model is further configured that: two groups of limiting plates 7 are arranged on the limiting disc 4, and multiple groups of limiting grooves 41 are all arranged between the limiting plates 7. With the design of this structure, it is convenient to limit the rotation of the handle 3 and avoid excessive rotation.
[0040] The present utility model is further configured that: the limiting plate 7 is arranged in a "冂" - shaped structure, and one end of the limiting plate 7 is screwed with a limiting bolt;
[0041] Multiple groups of connection holes 42 for inserting the limiting plates 7 are arranged on the limiting disc 4.
