Electric valve control box fluid resistance is small, small torque required when opening and closing; No installation direction requirements, bidirectional sealing, small flow resistance, long service life; When the gate is fully open, the erosion of the working medium is smaller than that of the globe valve; Mainly used for media is not restricted by the flow of water, sewage, oil, steam and other occasions, it is not recommended to use the media containing suspended particles in the occasion, if there is a switching speed requirement, can also be satisfied by increasing the number of valve stem threads or changing the output speed of the electric device. Electric valve control box is a supporting product of electric valve, used to control the opening and closing of electric valve, it can realize field control, can also realize remote control, and can accurately show the opening Angle of the valve from the Angle of the table head, for a large number of use of pipeline valves in petroleum, chemical, hydropower, metallurgy and other industries have indispensable significance. Electric valve control box controller is composed of the main circuit, control circuit and indicating circuit three departments. The working principle of the electric valve control box is as follows: Power on, the indicator light HW is on, indicating that the whole machine is powered on. When the valve is in the position between full open and full closed, the valve open indicator and the valve close indicator are not bright. Press the button SO, the AC contactor KO suction, the contact is connected to the motor power supply, the valve is opened, when the valve reaches the fully open position, the CAM contact pressure travel switch SLO, the normally closed contact is disconnected, so that the circuit blocks the AC contactor KO power stop work, the motor stop rolling. At the same time, a group of normally open contacts of SLO are closed, and the valve open indicator HG is on. Indicates that the valve is in full open position. The closing principle of the electric valve control box is the same as that of the valve opening. When the valve is opened or closed, if the torque on the output shaft exceeds the torque of the torque limiting mechanism, the micro switch STO, STC action stops the power supply of the contactor KO and KC, so that the motor stops rolling, at this time, the micro switch STO, STC action closed due to pressure, over button indicator HY bright indicates over torque. When the valve is opened or closed, follow the wire around the potentiometer arm roll, through the opening meter the size of the current is gradually changed, so as to show the degree of opening and closing of the valve. Electric valve control box rolling controller panel adjustment potentiometer, you can adjust the full degree of the opening meter.

Explosion-proof electric valve seven functional characteristics and two operating modes

Explosion-proof electric valve in the current life has been in a very popular position, and so that in the use of the above let us can be very effective to understand and familiar with it, it has a lot of functions, so that we can be very effective use will not make mistakes, its use environment we need to pay attention to should not be placed in a high temperature environment, And according to the actual relevant space factors for effective use, we are very necessary to determine and understand its own characteristics, can not be placed in direct sunlight, so that the machine case damage phenomenon, or the internal line occurred above the problem resulting in the overall use of the above.

Do you know how to accurately operate the explosion-proof electric valve so that the life and function of the equipment can be put to good use? In case you don’t know, here’s a sneak peek.

1. If you are using explosion-proof electric valves, you must first confirm repeatedly that all the premises are in line with each other before you can run. Many customers are affected by careless inspection, which affects the service life and function of the equipment.

2, after the operation of explosion-proof electric valve, do not too hard to control the equipment, but slowly to control if the external force is too large, it is not able to increase the function of the equipment will make the parts of the equipment due to excessive external force and distortion, thus affecting the equipment.

Function characteristics of explosion-proof electric valve:

1, improve the predecessor of no pin connection technology, so that the sealing function is more reliable, long service life, easy maintenance

2, the use of electroplating, nylon and other different coatings, corrosion resistance is improved, can meet the needs of different mining.

3, the valve appearance using spray coating, so that the product appearance anticorrosion function progress, beautiful appearance.

4, electric drive device function, its characteristics are as follows:

1) Small and light, easy to disassemble and repair, and can be installed at any Angle

2) Aluminum alloy die-cast shell can reduce electromagnetic interference

3) Integrated design of worm gear output shaft to avoid the gap of key connection and high transmission accuracy

4) The output shaft of the worm gear cast with copper alloy has high strength and good wear resistance

5) Microswitch with full entrance, more agile on and off, more safe to use

6) A variety of output signals: switch type, regulator type, intelligent type

7) With overheating protection, overload protection function, safety is guaranteed
