Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of guiding type pneumatic actuator for control valve.
Background technique
The driving mechanism of pneumatic actuator has two kinds of pinion and-rack and fork types, and the guiding type pneumatic actuator is to drive shift fork by the piston rod moving linearly to rotate, and then drives main shaft or valve rod rotates.Guiding type pneumatic actuator of the prior art mainly comprises cylinder part and shift fork transmission part, cylinder part comprises cylinder, cylinder head, piston and piston rod, the shift fork transmission part comprises pull-fork assembly, main shaft and casing, main shaft and pull-fork assembly are arranged in the casing, and main shaft and casing are rotationally connected, and pull-fork assembly and piston rod are in transmission connection, pull-fork assembly is when output torque, do not have special guide mechanism, just by piston and piston rod guiding, easily cause the jam phenomenon.
The model utility content
The utility model provides a kind of guiding type pneumatic actuator that has guide mechanism, can not produce the jam phenomenon for above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of guiding type pneumatic actuator, comprise cylinder assembly and pull-fork assembly, described cylinder assembly comprises cylinder, cylinder head, piston and piston rod, pull-fork assembly comprises shift fork, main shaft and casing, the end of described shift fork is provided with the first elongated chute, and the central position of described shift fork is provided with a through hole; Be provided with a bearing pin on the described piston rod, described bearing pin and the first chute are slidingly matched; Described main shaft is installed in the through hole at shift fork center; It is characterized in that, be provided with the second chute that passes for bearing pin on the described casing, described the second chute is elongated, and is parallel with piston rod.
Further setting of the present utility model is, described through hole is a splined hole.
Further setting of the present utility model is, described cylinder is two, is separately positioned on the both sides of casing, and two cylinders share piston rods.
Further setting of the present utility model is, is provided with damping device on described cylinder head and the casing.
Guiding type pneumatic actuator described in the utility model is by arranging the second chute of the long strip that passes for bearing pin at casing, and the first chute that long strip is set in the end of shift fork, so that the motion of shift fork has been subject to strict restriction and guiding, and then realized that the straight line motion with piston rod changes the rotating operation of shift fork into, and then the switching of control valve.This guiding type pneumatic actuator simple in structure, have guide mechanism, can not produce the jam phenomenon.
