Electric control valve is in accordance with high control precision, especially on the control of flow rate, and on the installation structure has obvious advantages, and widely used in industrial control system, or when we use the electric control Industrial Valves, or want to haunt us, appear all sorts of problems today is mainly about electric regulator for everyone within the cause and the treatment method of the leakage from the problems due to the analysis on the causes and solutions, had a very good ascension to d/repair personnel. Electric regulating valve at the time of processing or assembling received the influence of the process more, may cause electric control Industrial Valves leakage, the main problem is on the limit switch, mainly because of the limit switch is fixed, because in the valve control medium at runtime to regulator of scour and patterns, can lead to valve doesn't close and cause of leakage problems. The emergence of the problem is to adjust the position of the limit switch, can be solved. There are other problems: 1, the regulator when debugging undeserved cause of leakage. 2, due to the electric control valve in control part failure. Mainly because of the electric control valve in the valve limit switch, torque switch and because it also has the certain introduction. Due to the emergence of these problems will lead to the sealing surface wear or corrosion, mainly displays in trachoma pitting scratches, etc. , it is also a cause of leakage is a problem. The emergence of such problems mainly in the adjustment. 3, due to the electric actuator zero setting is not accurate, this is cause the valve will not be able to close. The main adjustment method: manual shut-off valve, or close the valve by hand twist don't get it back in half a circle, the to adjust the spacing adjustment. 4, the closing of the valves are pushed down type, if the actuator of the thrust is not big enough, can also cause the valve will not be able to fully closed, this is also one of the major problems of leakage. Solution: replace the big thrust actuator, or the type to balance valve core to reduce the unbalanced force of medium.
are important in ensuring resilient seated valve, and the machine is utilised by everyone from resilient seal gate valve to os & y valve fire protection.
