Description
Technical field
It the utility model is related to a kind of butterfly valve locking pin mounting structure.
Background technology
At present, the connector between the butterfly plate and valve rod of butterfly valve is mainly connecting pin, specially straight pin and taper bolt, this
The anti-drop function of two kinds of pins is not strong, in the case where butterfly valve switchs the operating mode with High Pressure Difference for a long time, sells in transmitting large torque, and pin is easily de-
Fall, cause butterfly valve seal to fail, and then cause the damage of valve and the generation for accident of stopping, currently used anticreep means are pin
After the completion of assembling, in the connecting end surface spot welding of butterfly plate and pin, this anticreep method can cause dismounting difficult in maintenance, Er Qiexiao
Scrap, can not reuse after splitting out.
Utility model content
The purpose of this utility model is in order to solve the above-mentioned technical problem, and to provide a kind of butterfly valve locking pin mounting structure,
It is superior with shank anti-drop function so as to fulfill butterfly valve.In order to achieve the above object, technical solutions of the utility model are as follows：
Butterfly valve locking pin mounting structure, including valve rod, the dish plate that is sheathed on valve rod, run through the valve rod in the dish plate
Equipped with pin hole, the pin hole internal clearance is equipped with butterfly valve locking pin, and the butterfly valve locking pin includes body, arranged on intrinsic core
Axis, one end of the body offer circumferentially uniformly distributed some notch, and the notch is extended in the middle part of the body, the mandrel
Tapered portion including cylindrical portion, arranged on cylindrical portion one end, arranged on the threaded portion of the cylindrical portion other end, the threaded portion extend institute
State body.
Specifically, the body is cylindrical structure.
Docked specifically, the tapered portion coordinates with the body interior.
Specifically, the threaded portion is equipped with the fixing piece of corresponding fastening.
Specifically, the fixing piece is nut.
Compared with prior art, the beneficial effect of the utility model butterfly valve locking pin mounting structure is mainly reflected in：Pass through
Body and the mating connection of mandrel tapered portion, have anticreep effect；The notch opened up by body peripheral, makes body have elasticity
The ability of deformation, fastens mandrel；Mandrel extends body and is equipped with threaded portion, its dismounting is fixed conveniently, reusable.
Brief description of the drawings
Fig. 1 is the mounting structure schematic diagram of the utility model embodiment；
Fig. 2 is the present embodiment butterfly valve locking pin structure diagram；
Digital representation in figure：
1 valve rod, 11 dish plates, 12 pin holes, 2 bodies, 21 mandrels, 22 notch, 23 tapered portion, 24 threaded portions, 25 cylindrical portions, 26
Fixing piece.
Embodiment
Clear, complete description will be carried out to the technical scheme in the embodiment of the utility model below in conjunction with the accompanying drawings, it is clear that
The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Embodiment：
With reference to shown in Fig. 1-2, the present embodiment is butterfly valve locking pin mounting structure, including valve rod 1, is sheathed on valve rod 1
Dish plate 11, dish plate 11 is interior to be equipped with pin hole 12 through valve rod 1, and 12 internal clearance of pin hole is equipped with butterfly valve locking pin.
Butterfly valve locking pin includes body 2, the mandrel 21 in body 2.Body 2 is cylindrical structure, one end of body 2
Circumferentially uniformly distributed some notch 22 are offered, notch 22 extends to the middle part of body 2.
One end of mandrel 21 is equipped with tapered portion 23, and the other end of mandrel 21 is equipped with threaded portion 24 and extends body 2.Taper
Portion 23 is docked with 2 internal engagement of body, and tapered portion 23 is corresponding with notch 22.The middle part of mandrel 21 is cylindrical portion 25.Threaded portion 24
Fixing piece 26 equipped with corresponding fastening, the present embodiment fixing piece 26 are nut.
During using the present embodiment, the pin hole 12 between dish plate 11 and valve rod 1 is accomplished fluently in advance, body 2 and mandrel 21 are assembled
It is ready, 2 one end of body containing tapered portion 23 is loaded into pin hole 12, and it is assembled depth in place；Nut is loaded into mandrel 21
Threaded portion 24, tighten fixation, under the pulling force effect of nut, the tapered portion 23 of mandrel 21 produces body 2 outside extruding
Power, meanwhile, the circumferentially disposed notch 22 of body 2, makes the periphery of body 2 produce outside elastic deformation, so as to reach wedging
With the effect of anticreep.
When needing to remove maintenance, come loose nut, and the wedging power between body 2 and pin hole 12 eliminates, and body 2 and pin hole
Matching somebody with somebody between 12 is combined into clearance fit, you can takes out body 2.
The present embodiment has anticreep effect by the mating connection of body 2 and 21 tapered portion 23 of mandrel；Outside by body 2
The notch 22 of Zhou Kaishe, the ability for making body have elastic deformation, fastens mandrel 21；Mandrel 21 extends body 2 and is equipped with screw thread
Portion 24, makes its dismounting be fixed conveniently, reusable.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality
New protection domain.
