Abstract
A kind of more spring cylinder piston actuators of heavy-load type, including push rod, lower cover of air cylinder, push rod rotating prevention sleeve, cylinder body, dive key, spring, air cylinder tie rod, piston, clamp nut, cylinder upper cover and handwheel part, push rod rotating prevention sleeve is provided with keyway, push rod rotating prevention sleeve is fixed by bolts on lower cover of air cylinder, piston and push rod are tightened together with clamp nut, feather key is housed on push rod, feather key slides on the keyway of push rod rotating prevention sleeve, piston-deflection caused by spring during for limiting executing agency's action, positioning sleeve is welded with piston, for the position of fixed spring, air cylinder tie rod is fastening lower cover of air cylinder, cylinder body and cylinder upper cover.The size of executing agency is greatly reduced using the utility model, saves cost, easily facilitates transport and installation.This executing agency includes two kinds of forms of positive interaction and reaction, with handwheel and without two kinds of specifications of handwheel.
Description
Technical field：
Executing agency's technical field is the utility model is related to, more particularly to a kind of more spring cylinder piston types of heavy-load type perform
Mechanism, the mechanism are that a kind high-thrust single acts on more spring cylinder piston actuators, and the pneumatic actuator is used to control
Straight stroke valve acts.
Background technology：
Pneumatic actuator is the common equipment of industrial process control field, it be widely used in chemical industry, oil, metallurgy,
The industries such as electric power.Pneumatic actuator and other pneumatic control annexes are used cooperatively, and can receive the aperture of control signal control valve,
And then the flow of control pipeline medium.
Single-acting pneumatic actuator one kind currently used for control valve is more spring diaphragm type pneumatic actuators, its by
Pressure element is rubber diaphragm, easy aging, damage, and its supply gas pressure is limited to membrane ruggedness, and service pressure only has
0.45MPa or so, so thrust output scope is also smaller.And its spring scope of design is narrower, if it is defeated to change executing agency
Go out thrust, otherwise integral replacing spring, or changing executing agency, easily causes economic loss.Another is cylinder piston
Formula executing agency, its form of springs are Single spring, and thrust range is limited, are not easy to change executing agency's thrust, and executing agency's chi
It is very little too big.
Utility model content：
In view of this, it is necessary to provide a kind of heavy-load type more spring cylinder piston actuators.
A kind of more spring cylinder piston actuators of heavy-load type, including push rod, lower cover of air cylinder, push rod rotating prevention sleeve, cylinder body,
Dive key, spring, air cylinder tie rod, piston, clamp nut, cylinder upper cover and handwheel part, push rod rotating prevention sleeve are provided with keyway,
Push rod rotating prevention sleeve is fixed by bolts on lower cover of air cylinder, and piston and push rod are tightened together with clamp nut, is equipped with and is led on push rod
Xiang Jian, feather key slide on the keyway of push rod rotating prevention sleeve, for limiting piston-deflection caused by spring when executing agency acts,
Positioning sleeve is welded with piston, for the position of fixed spring, air cylinder tie rod is fastening on lower cover of air cylinder, cylinder body and cylinder
Lid.
The concrete operating principle of pneumatic actuator is, when executing agency is used cooperatively with other control annexes, to receive
Control signal, compressed air is inputted from air inlet, executing agency's push rod 1 is stretched out, and band movable valve is closed, when executing agency receives
When control signal is vented, push rod 1 is retracted in the presence of compression spring, and band movable valve is opened.Spring of the present utility model uses
Modularized design, the thrust output of executing agency can be changed by adjusting number of springs according to being actually needed, and Single spring is held
Row mechanism wants change thrust output and is merely able to redesign spring or changes executing agency, can so cause greatly not
Just.
In this way, being greatly reduced the size of executing agency using the utility model, cost is saved, easily facilitates transport
And installation.This executing agency includes two kinds of forms of positive interaction and reaction, with handwheel and without two kinds of specifications of handwheel.
Brief description of the drawings：
Fig. 1 is the cut-away section structural representation of the more spring cylinder piston actuators of heavy-load type.
In figure：Push rod 1, lower cover of air cylinder 2, push rod rotating prevention sleeve 3, cylinder body 4, dive key 5, spring 6, air cylinder tie rod 7, piston
8th, clamp nut 9, cylinder upper cover 10, handwheel part 11.
Embodiment：
Please refer to Fig. 1, the more spring cylinder piston actuators of heavy-load type, including push rod 1, lower cover of air cylinder 2, push away
Bar rotating prevention sleeve 3, cylinder body 4, dive key 5, spring 6, air cylinder tie rod 7, piston 8, clamp nut 9, cylinder upper cover 10 and handwheel portion
Part 11, push rod rotating prevention sleeve 3 are provided with keyway, and push rod rotating prevention sleeve 3 is fixed by bolts on lower cover of air cylinder 2, and piston 8 and push rod 1 are used
Clamp nut 9 is tightened together, and feather key 5 is housed on push rod 1, and feather key 5 is slided on the keyway of push rod rotating prevention sleeve 3, is used for
Piston 8 caused by spring deflects during the action of limitation executing agency, positioning sleeve is welded with piston 8, for the position of fixed spring 6
Put, air cylinder tie rod 7 is fastening lower cover of air cylinder 2, cylinder body 4 and cylinder upper cover 10.
The concrete operating principle of pneumatic actuator is, when executing agency is used cooperatively with other control annexes, to receive
Control signal, compressed air is inputted from air inlet, executing agency's push rod 1 is stretched out, and band movable valve is closed, when executing agency receives
When control signal is vented, push rod 1 is retracted in the presence of compression spring, and band movable valve is opened.Spring of the present utility model uses
Modularized design, the thrust output of executing agency can be changed by adjusting number of springs according to being actually needed, and Single spring is held
Row mechanism wants change thrust output and is merely able to redesign spring or changes executing agency, can so cause greatly not
Just.
