た。Conventionally, a valve opening/closing device VC+a worm reducer has often been used. One of the reasons for this is that a worm reducer can achieve a large reduction ratio with just one stage, and the other is that a torque limit switch can be easily added by inserting a spring into the worm's thrust support. By having. On the other hand, when opening and closing the valve,
At the closed end, an appropriate torque must be applied to the valve stem to prevent damage to the valve body and valve seat and to prevent leakage.
In addition, when the valve is started to open, the valve body is fixed to the valve seat and the valve stem is fixed to the female thread of the valve stem, and these are often firmly fixed due to rust, so generally a stronger torque is required than the torque when the valve is closed. Therefore, the worm speed reduction device with the above-mentioned characteristics was a suitable speed reduction device for a valve opening/closing machine. However, the worm reducer inevitably has a low power transmission efficiency due to its structure, and is heavy in relation to the transmitted torque.Furthermore, due to its unique shape, the weight balance is poor and it cannot be made compact due to its design. Therefore, when automating the process by attaching an opening/closing device to the valve, we had to face difficulties in terms of space and strength. As a result of extensive experimental research, the inventors of the present invention have discovered that the above-mentioned problems can be solved by adopting a planetary gear reduction mechanism in place of the Waohm reduction gear, and have arrived at the present invention.
