Electric valve manufacturers: What is the manual control method of the electric valve actuator?
Electric valve manufacturer: The valve electric actuator is used to manipulate the valve. If the valve cannot be opened and closed due to certain elements, such as power failure and common faults of the electric actuator, or when it is fixed in a certain part, the actual operation is completed through the spindle. So, when the valve actuator to carry out manual control should pay attention to what?
1, the power switch valve should pay attention to the correct road
The opening and closing of the valve will be fixed when the direction, in general, the opposite direction indicates that the valve is opened, and the clockwise direction also indicates that the valve is closed. When necessary, manual operation of the valve electric actuator, when in use must pay attention to the right way to open or close the valve.
2, remember not to rely on special tools for actual operation
Because the main shaft, rocker and other behavioral components in the valve are customized according to this human resource, when manually controlling the electric actuator of the valve, attention should also be paid to the actual operation by hand immediately, instead of relying on lever or long wrench tools to open or close the valve to prevent damage caused by too much force. In addition, when the main shaft is fully opened, it should be reversed by a small amount to make the middle of the screw teeth tight and avoid loose damage.
3, pay attention to do a good job of identification
If the main shaft of the valve electric actuator will be used for positioning, it needs to be in the reserved part. During maintenance, attention should be paid to marking the opening and closing positions with ruler and oily marker, so as not to offend the fixed point when opening and closing. In addition, before manually controlling the valve electric actuator, the operator should also pay attention to loosen the spindle pipe hoop before operating. If there is no special indication after the actual operation, the spindle must be opened and locked with the pipe hoop.
Electric valve manufacturers: What are the structural characteristics of electric butterfly valves
1, compact and lightweight, very easy to disassemble and repair, and can be assembled from random parts.
2. The structure is compact and tight, the control torque is small, and the 90 ° rotation opens quickly.
3, flow characteristics tend to parallel lines, adjust the cost-effective.
4, butterfly plate and valve seat connection selection of non-nut structure, to solve the likely and internal leakage point.
5. The inner hole of the butterfly plate is designed with curved surface, which improves the sealing characteristics and can prolong the service life of the valve, and still maintains zero leakage above the 50000 pressure relief opening and closing.
6. The hydraulic seal can be disassembled and replaced, and the sealing performance is reliable and double-sealed.
7. The butterfly board can be painted according to customer needs, such as polyester or PTFE.
8. The valve can be designed for flange connection and clip type access.
9. The driving form can be manual, electric or pneumatic.
