We know that many gate valves are manual and electric two categories, the shortage of manual valves is that they must rely on human resources manual type to carry out the power switch, not only the actual operation inconvenience, but also can not be automated equipment or remote operation, and electric valves are particularly good solution to the above mentioned problem.
Electric valves mostly see magnetic force to promote, its valve body is equipped with a magnet coil, wash the car into the water solenoid valve after plugging in with the magnet coil of magnetism, attract the same prefabricated components containing magnetism caused by the movement and bias, and then complete the gate valve open or closed. The shortage of this type of household water with normally open solenoid valve is due to the electric part set in the valve body, very easy to cause fire or short circuit conditions, when the gate valve is used in places such as natural gas pipelines there are security risks, in addition, because it is different from the manual valve in the construction, so that the lack of exchange between the two parts, but also to the stainless steel anti-corrosion solenoid valve manufacturing and maintenance caused by the same.
Therefore, in order to solve the above problems, and developed a higher safety factor, solar solenoid valve with practical, and conducive to manufacturing and maintenance of the new type of electric valve.
The new type of electric valve gate by the valve body, motor, valve seat, control system, reducer, reducer output shaft, its characteristics depend on the motor is located outside the valve body, with control system and reducer, reducer with reducer output shaft, reducer according to the reducer output shaft and valve seat connection, direct-acting solenoid valve manufacturer valve seat from the top of the valve body widened to the valve body.
Because the new type of electric valve is not plugged in the valve body, so the internal structure of the three five usually open solenoid valve does not produce fire or short circuit conditions, and thus has a better safety factor in many places. And because of the motor's own insulation resistance and sealing with the motor and valve body in the middle of the alternating current and fire is protected, so even if the motor sparks and go electric and other accidents, will not endanger the 2WB normally closed solenoid valve body internal structure.
