A kind of retarder travel control device of control valve belongs to the technical field of control valve fitment.Including speed reducer housing, it is characterized in that being equipped with micromotor, travel switch component, stroke plectrum above the speed reducer housing, the related stroke of valve plectrum of the stroke plectrum is formed with valve opening stroke plectrum, and on output main shaft, closes stroke of valve plectrum and valve opening stroke plectrum and touch cooperation control micromotor rotation with travel switch component.Above-mentioned utility model has the following technical effect that：Cooperation is touched by two plectrums and two travel switches, it is 0 300 ° that can reach output main axis stroke range, and rotational travel angle can arbitrarily be adjusted by exporting main shaft in the range, easy to operate.
Description
Technical field
The utility model belongs to the technical field of control valve fitment, and in particular to a kind of retarder Stroke Control of control valve
Device.
Background technology
The keying for controlling valve core is a mechanical action, it is therefore desirable to a controller carries out automatically controlling it,
And this mechanical action cannot be completed in moment, therefore just need to configure one speed reducer travel control device.And existing subtract
Fast device travel control device all only with the cooperation of a stroke plectrum and travel switch, can only achieve one and open the work(closed substantially
Can, the stroke range of output main axis cannot be controlled in the larger context, and Stroke Control range is small, and stroke is fixed, no
It can adjust, limitation is big.
Utility model content
In view of the above defects of the prior art, the utility model aim is to provide a kind of retarder of control valve
The technical solution of travel control device.
A kind of retarder travel control device of control valve, including speed reducer housing, it is characterised in that outside the retarder
Micromotor, travel switch component, stroke plectrum be installed above shell, the related stroke of valve plectrum of the stroke plectrum with open
Stroke of valve plectrum forms, and on output main shaft, closes stroke of valve plectrum and valve opening stroke plectrum and is touched with travel switch component
Connect cooperation control micromotor rotation.
A kind of retarder travel control device of the control valve, it is characterised in that the pass stroke of valve plectrum with open
Stroke of valve plectrum is rotatably fixed on by locking nut on output main shaft.
The retarder travel control device of a kind of control valve, it is characterised in that travel switch component includes switch branch
Upper stroke switch and lower stroke switch is arranged in frame on switch bracket, and valve opening travel switch touches cooperation with upper stroke switch, closes
Stroke of valve is switched touches cooperation with lower stroke switch.
The retarder travel control device of a kind of control valve, it is characterised in that the switch bracket is in body of rectifying
Structure is simultaneously fixed on speed reducer housing, and the body top of rectifying is fixedly connected with upper stroke switch, and body lower part of rectifying is fixedly connected down
Travel switch.
Above-mentioned utility model has the following technical effect that：Cooperation is touched by two plectrums and two travel switches, it can
To reach output main axis stroke range for 0-300 °, rotational travel angle can arbitrarily be adjusted by exporting main shaft in the range,
It is easy to operate.

Specific implementation mode
Below in conjunction with attached drawing the utility model is described in further detail explain.
As shown in Figs 1-4, the retarder travel control device of a kind of control valve, including speed reducer housing, the retarder
Micromotor 4, travel switch component 6, stroke plectrum 2 are installed, the 2 related stroke of valve of stroke plectrum is dialled above shell
Piece 22 and valve opening stroke plectrum 21 form, and on output main shaft 3, close stroke of valve plectrum 22 and valve opening stroke plectrum 21 with
Travel switch component 6 touches cooperation control micromotor 4 and rotates.The pass stroke of valve plectrum passes through with valve opening stroke plectrum
Locking nut is rotatably fixed on output main shaft.Travel switch component includes switch bracket 7, is arranged on switch bracket 7
Travel switch 61 and lower stroke switch 62, valve opening travel switch 21 touch cooperation with upper stroke switch 61, close stroke of valve switch 22
Cooperation is touched with lower stroke switch 62.The switch bracket physique structure and is fixed on speed reducer housing in rectifying, described to rectify
Body top is fixedly connected with upper stroke switch, and body lower part of rectifying is fixedly connected with lower stroke switch.
The control valve electric execution mechanism stroke control device is mechanical touching formula structure, exports and assembles two rows on main shaft
Journey plectrum, two stroke plectrums can arbitrarily be rotated around main shaft, be respectively used to control stroke beginning and terminal location, valve opening row
Journey plectrum can arbitrarily select to install with stroke of valve plectrum or more is closed, and have locking nut to be fixed on stroke plectrum.For solid
The switch bracket of fixed two travel switches rectified under body or other specific shapes is fixed on speed reducer housing, and valve opening stroke is dialled
Piece and pass stroke of valve plectrum touch cooperation with two travel switches respectively, control the beginning and terminal location of stroke.The structure can
Output main axis stroke range is set arbitrarily to adjust rotational travel angle within the scope of 0-300 °, use scope is wide, easy to operate
The features such as.
