Abstract
The utility model provides a zero clearance draw -in groove coupling mechanism of executor main shaft and valve rod. Being equipped with connecting clamp subunit spare at main shaft and valve rod middle part, being equipped with the clip in the both sides of valve rod, be equipped with the clip hole on the clip of both sides respectively, the both sides clip passes through the anti -loosening screw card and on the valve rod, is equipped with the spring between the valve rod of both sides clip. The utility model discloses simple structure is reliable, realizes that no clearance fit connects, can observe whether to install targetting in place, prevent to install the direction mistake. It is suitable applied with the dirty clearance draw -in groove coupling mechanism of valve rod as the executor main shaft.
Description
Technical field
This utility model provides the gapless draw-in groove bindiny mechanism of executor's main shaft and valve rod.
Background technology
At present, executor's main shaft is connected to adopt screw thread transition connected mode more with valve rod, and main shaft is tired with threaded stem processing
Difficulty, installs inconvenient, and it is difficult to ensure that axiality after main shaft and valve rod installation, easily produces at diameter of thread in work process
Raw stress concentration, main shaft is easily snapped off with valve rod, causes executor's cisco unity malfunction.
Utility model content
In order to overcome the shortcoming of executor's main shaft and valve rod bindiny mechanism, the utility model proposes a kind of simple and practical
Executor's main shaft and the gapless draw-in groove bindiny mechanism of valve rod.This mechanism passes through to install spring and clip on valve rod, solves valve
The technical problem that door executor's gapless draw-in groove connects.
This utility model solves the scheme that adopted of technical problem：
In main shaft and valve rod middle part equipped with connection clip assembly, in the both sides of valve rod equipped with clip, on the clip of both sides
It is respectively equipped with clamp hole, both sides clip is stuck on valve rod by backing-up screw, equipped with spring between the valve rod of both sides clip.Institute
Stating has two plane of symmetry boss on clip, in the wedging straight ring groove of main shaft.Described clip is provided with observation port.
Good effect, this utility model is simple and reliable for structure, realizes blind-mate and connects；Can see whether to be installed to
Position, prevents installation direction mistake.The suitable dirty gap draw-in groove bindiny mechanism application as executor's main shaft and valve rod.
Brief description
Fig. 1 is this utility model structure chart；
Fig. 2 is this utility model exploded view.
In figure, 1. main shaft, 2. connection clip assembly, 2.1. clip, 2.2. spring, 2.3. clamp hole, 2.4. backing-up screw,
3. valve rod.
Specific embodiment
According to the figure, in main shaft 1 and valve rod 3 middle part equipped with connecting clip assembly 2, in the both sides of valve rod equipped with clip
2.1, both sides clip is respectively equipped with clamp hole 2.3, both sides clip is stuck on valve rod by backing-up screw 2.4, in both sides clip
Valve rod between equipped with spring 2.2.
Two plane of symmetry boss are had on described clip, in the wedging straight ring groove of main shaft.
Described clip is provided with observation port.
Utility model works process：
When backing-up screw is screwed into clip screwed hole, spring-compressed, clip and clip near motion, be finally clamped in main shaft with
On valve rod, when unclamping backing-up screw, recoil of spring, drive clip to separate with clip, depart from main shaft and valve rod simultaneously.
Have on clip in the two symmetrical slope boss wedging straight ring grooves of main shaft, realize gapless draw-in groove and connect so that pressing from both sides
Son loads main shaft guiding, easily makes in the inclined-plane wedging straight ring groove of main shaft.Enter clip and clamp main shaft and valve rod
Meanwhile, main shaft is controlled to be connected with valve rod no axial float.There is gap, to fully achieve by two symmetrical slopes between main shaft and valve rod
The strength transmission to main shaft and valve rod for the boss.
Clip is provided with observation port, and clip is provided with observation port, can observe docking of main shaft and valve rod in installation process
Whether situation, can be put in place by observation port inspection assembling after installation terminates simultaneously.Clip screwed hole is provided with turnup structure,
Increase screw thread effective length.
Clip is provided with two symmetrical slope boss, is similarly provided with two symmetrical slopes in clip with the symmetrical position of observation port convex
Platform, clip is identical with clip two symmetrical slope boss structure.
Two symmetrical slope boss positions are in a center of symmetry with observation port, and clip assembly clamping is when main shaft is with valve rod regardless of anti-
Just, anti-loaded in preventing from installing.
Advantage of the present utility model：
1. simple and reliable for structure, realize blind-mate and connect；
2. can see whether to be installed in place, prevent installation direction mistake.
