How to Use The Declutch Gear Box - Manual Override For Pneumatic Actuators
(pneumatic hand wheel, pneumatic handwheel operation box, pneumatic drive box )(pneumatic hand wheel, pneumatic handwheel operation box, pneumatic drive box )
Declutch gear box which is used in conjunction with a pneumatic device to open 90° butterfly valves, ball valves, etc., to achieve manual or pneumatic drive.
1. Small size, light weight, reasonable design, novel style;
2. Product serialization, output torque and pneumatic devices, various valve configurations.
3. The inner hole of the worm gear connection is made of an octagonal structure, or it can be specially customized with additional money to make an angle connection or a key connection, so that the user can choose the position of the device relative to the valve body according to the needs.
Features of Declutch Gear Box :
●The product is serialized, and the output torque matches the pneumatic device and valve.
●Small size, light weight, reasonable design, novel style;
●Pneumatic, manual dual-purpose. Rotate the eccentric hand lever device 90°, the handle is in the upper position, and it is operated manually. The handle is located in the lower position and is operated pneumatically.
●Two keyways with a distance of 90° are made in the inner hole of the worm gear connection, so that the user can choose the relative position of the device and the valve body according to the needs.
●The product is equipped with special lubricating grease, and after being assembled with the valve, it is integrally sealed, dustproof, waterproof, and the protection level is IP65.
Instructions for use
The bottom surface of the reducer is connected with the valve, the upper bracket surface is connected with the cylinder, the valve shaft fits through the inner hole of the worm wheel, and the square end of the valve shaft fits with the square hole of the cylinder; (working process: when pneumatic, the cylinder drives the valve shaft,
The worm gear rotates together. In manual operation, the worm meshes with the worm gear to drive the valve shaft to rotate, and the cylinder piston also moves accordingly).
●The handle is located at the upper position, manual operation, not pneumatic. Pull out the limit pin and turn the handle clockwise to the down position. The worm wheel and worm are disengaged to realize pneumatic.
●When the handle is in the down position, it is pneumatically operated and cannot be operated manually. Pull out the limit pin and turn the handle counterclockwise to the upper position. The worm gear and worm are meshed to realize manual operation. Pneumatic switching manual process will
If the top tooth phenomenon occurs, it is necessary to turn the handwheel at an angle to ensure that the worm wheel and the worm are meshed correctly before manual operation.
●Pneumatic and manual can not be driven at the same time.
