The manually operated butterfly valve is a pneumatic butterfly valve

The drive butterfly valve with manual operation is based on the pneumatic butterfly valve, with the addition of a manual operation turbine box or manual operation handle. There is a clutch on the manual turbine box, and the clutch should be turned. It can be switched between pneumatic and manual when the gas source fails.

The pneumatic butterfly valve can be operated by switching to manual operation mode using the handwheel and B-wheel box. It controls the opening and closing of valves through manual operation devices. When using and maintaining pneumatic butterfly valves with manual operation, the following aspects should be noted:

1. Operating standards: Use manual operating devices according to the correct operating methods to avoid damage or accidents caused by excessive force or improper operation.

2. Regular inspection: Regularly check the working status of the manual operating device to ensure its normal operation and flexibility. If there are any abnormalities, they should be repaired or replaced in a timely manner.

3. Cleaning and maintenance: Regularly clean the manual operating device according to usage and equipment requirements, remove dust, dirt, etc., keep its surface clean, and pay attention to lubrication of the lubrication parts.

4. Pay attention to safety: When operating pneumatic butterfly valves with manual operation, pay attention to safety, such as cutting off the power supply, emptying the gas source, etc., to avoid accidents.

The above are some precautions for pneumatic butterfly valves with manual operation. The specific use and maintenance should be carried out according to the actual situation and equipment requirements. If there are more specific questions, please provide detailed information so that I can better answer them.

There is usually a manual operating device on the actuator, such as a handwheel or handle, which can directly control the opening and closing of the valve by rotating or pulling the manual operating device. This manual control method is suitable for situations where frequent adjustment of valve opening is required, and the operation is simple and convenient.

There are many types of manual operating devices, including:

1. Handwheel: Control the opening and closing of valves by rotating the handwheel, suitable for smaller valves.

2. Handle: Control the opening and closing of the valve by pushing and pulling the handle, suitable for larger valves.

3. Spiral rod: By rotating the spiral rod to control the opening and closing of the valve, it is suitable for some situations that require precise adjustment.

4. Joystick: Control the opening and closing of valves by shaking the joystick up and down or left and right, suitable for situations that require quick response.

5. Pull rod: Control the opening and closing of the valve by pulling the pull rod, suitable for some situations that require remote operation.

6. Foot pedal: Control the opening and closing of valves by stepping on the foot pedal, suitable for some situations that require manual operation.

Different types of manual operating devices are suitable for different situations and can be selected according to actual needs.

When cleaning and maintaining manual operating devices, the following aspects should be noted:

1. Cut off the power: Before cleaning and maintaining the manual operation device, be sure to cut off the power to avoid electric shock accidents.

2. Clean the surface: Use a clean cloth or brush to clean the surface of the manual operating device, remove dust, dirt, etc., and avoid affecting its normal operation.

3. Lubrication parts: For parts that require lubrication, appropriate lubricants can be used to reduce friction and wear.

4. Check fasteners: Check the fasteners of the manual operating device, such as bolts, nuts, etc., to ensure that they are firmly fastened and avoid looseness that may cause inaccurate or dangerous operation.

5. Replacement of vulnerable parts: According to usage and manufacturer requirements, regularly replace vulnerable parts of manual operating devices, such as sealing rings, springs, etc., to ensure their normal operation and reliability.

6. Pay attention to safety: When performing cleaning and maintenance, be sure to pay attention to safety, such as cutting off the power supply, emptying the gas source, etc., to avoid accidents.

The above are some aspects to pay attention to when cleaning and maintaining manual operation devices. Specific cleaning and maintenance should be carried out according to the actual situation and equipment requirements.
