Description
Technical field
The present invention relates to a kind of actuator, be specifically related to a kind of cylinder type actuator.
Background technique
Bleed pressure that cylinder type actuator can bear is high, thrust is large, travel speed is fast and sturdy and durable.Adapted double-purpose valve door holder, pure pressurized air is accepted in the upper and lower of cylinder simultaneously, and discord corrosive atmosphere environment carries out gas exchange, never corrosion, long service life.When normal work, press the action of double-acting cylinder actuator, when air failure, spring can make spool safety reset, makes valve closing or opens.
Cylinder actuating mechanism in running, exist acceleration, at the uniform velocity, the stage such as deceleration, be therefore controlled in practice and seem very important for the travel speed of actuator.
Summary of the invention
The invention provides a kind of cylinder type actuator, this actuator can increase the travel speed of adjusting actuator, has solved the speed issue that cylinder actuating mechanism runs in running.
Object of the present invention reaches by the following technical programs:
One cylinder type actuator, comprise cylinder, push rod, be arranged on the support and the piston that has hole that is arranged on cylinder interior support top of cylinder below, cylinder head is provided with the adjusting screw that extends to cylinder interior, adjusting screw below linking springs cover, between spring shield and piston, be connected with Returnning spring, cylinder bottom is connected with support by cylinder snap ring, push rod bottom is arranged on internal stent, push rod top extends to cylinder interior through the hole of piston, push rod upper outside is provided with push rod separation sleeve, push rod separation sleeve one end is connected with the locking nut that push rod upper end arranges, one end and piston contact, push rod lower outside is also provided with push rod bellows or spring.When need actuator in running speed time, can in cylinder, pass into gas or reduce gas, thereby the elastic force of receiving that changes Returnning spring changes the thrust that push rod is subject to, and then changes the deformation quantity of push rod bellows or spring, regulates needed travel speed.Returnning spring, in the time of air failure, uses as the parts of safety reset.
Described push rod below is provided with pushrod clip, and pushrod clip and the slide bar being arranged on internal stent one side vertical direction are slidably connected, and in described support, are provided with stroke scale with respect to a side of slide bar.The stroke of the actuator under corresponding pressure can be accurately known in the setting of pushrod clip and stroke scale, thereby can know travel speed, knows the performance of actuator.
Described push rod and support contact segment are provided with lining on push rod, and on push rod, lining below is provided with lining under push rod, is also provided with support push rod O type circle on push rod under lining and push rod between lining.The setting of the upper and lower lining of push rod can make push rod and support close contact prevent push rod landing.
Described piston is provided with piston O type circle.
Described support top is provided with support O type circle.
The setting of a series of O type circles can, by tight actuator's inner sealing, improve the performance of whole actuator.
The present invention compared with prior art, there is following advantage and beneficial effect:
The present invention is provided with push rod bellows or spring in the bottom of push rod, can be according to needed speed in actual motion, adjust the gas flow in cylinder and then change the deformation quantity of push rod bellows or spring, thereby reach the object of the opening speed that changes actuator.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Embodiment 1
As shown in Figure 1, one cylinder type actuator, comprise cylinder 1, push rod 6, be arranged on the support 2 and the piston that has hole 8 that is arranged on cylinder 1 internal stent 2 tops of cylinder 1 below, cylinder 1 top is provided with the adjusting screw 3 that extends to cylinder 1 inside, adjusting screw 3 below linking springs covers 4, between spring shield 4 and piston 8, be connected with Returnning spring 5, cylinder 1 bottom is connected with support 2 by cylinder snap ring 11, push rod 6 bottoms are arranged on support 2 inside, push rod 1 top extends to cylinder 1 inside through the hole of piston 8, push rod 6 upper outside are provided with push rod separation sleeve 9, push rod separation sleeve 9 one end are connected with the locking nut that push rod upper end arranges, one end and piston contact, push rod 6 lower outsides are also provided with push rod bellows 7 or spring.
Cylinder 1 top is provided with suction port, and gas enters cylinder 1 inside by this suction port, and promotion piston 8 moves and also changes the elastic strain of Returnning spring 5, thereby promotes pushrod movement, and band movable valve plug is opened or closes.
Returnning spring 5, in the time of air failure, uses as the parts of safety reset.When being typically designed to, flow direction valve in the time losing gas, help actuator to reply.
The travel speed of actuator need to be accelerated, need to change the air content in cylinder, the elastic strain of the Returnning spring in intensifying cylinder, thereby the elastic strain that strengthens push rod bellows 7 or spring.
If desired the travel speed of actuator is slowed down, need to reduce the elastic strain of the Returnning spring in cylinder, thereby the elastic strain that reduces push rod bellows or spring achieves the goal.
