5, electric regulator adjusting questions over the internal leakage of the affected by the processing, the assembly process, electric regulator exists widely held still won't open locked after electric phenomena, such as through the action of upper and lower limit switch position of the electric control valve stroke debugging a little bit small, the exposed electric regulating valve closed lax or valve open exhibition not ideal conditions; The electric control valve stroke debugging a bit bigger, actuating torque switch try our best to take care of; If will be a bigger torque switch action value of debugging, would crash out lower speed transmission due to the structure or damaged valve, even to destroy motor burning accident. 6, selection is not correct lead to valve actuating cavitation corrosion of electric regulator of leakage of cavitation related to pressure difference, when the actual pressure differential valve delta P is greater than the critical pressure difference of cavitation delta Pc, born cavitation, in the process of cavitation bubbles, cracks in can release a large + 羭 strands, the valve seat, valve core throttling components such as initiation mutilate utility, ordinary valve under the condition of cavitation is run no more than three months, and even more the split-second, namely the valve was suffered from serious cavitation corrosion, so that the seat of the leak amount up to the fixed flow 30 more than one hundred percent, this is no way to remedy, because of this, different use electric door have different specific technical requirements, in accordance with the system process to reasonable selection of electric control valve is shut. 3, electric control valve production quality actuating leak valve production manufacturer of valves in the process of producing materials, processing process, assembly process, such as stem is lax, so tightly closed grinding is not suitable for standard, the pitting, trachoma and other defective products not completely take off, led to the electric control valve leakage. The solution: the new debugging limit. 2, the valves are pushed down closed type, thrust of the actuator is not big enough, the moment of no pressure adjustment is easy to achieve, fitted with thrust, can not overcome the liquid of thrust, so does not reach the designated position. The solution: the new processing tightly closed surface. Solution: implement process improvement, choose multi-stage decompression or sleeve regulator. Solution: change the big thrust the execution of the vessel with the valve structure, type or the balanced valve core to minimize media injustice balance. To solve this problem, in general, electric regulator to adjust the manual will be electric control Industrial Valves to the end, to open a circle, again set the lower limit of the electric door switch position, then the electric control valve to open to the whole paper set maximum limit switch position, so the electric regulating valve will not manifest manually locked after electric wouldn't open phenomenon, ability to make the electric door open and close operation, but they were actuating aeriform in electric gate leakage. 4 local influencing valves, electric control valve stem leakage of electric control valve in the traditional form is through the valve stem lam position switch, such as over torque switch mechanical stem form, because the stem components affected by the background of temperature, pressure, moisture, lead to valve positioning, spring fatigue, thermal expansion coefficient of warp equal to objective factors, cause the electric control valve leakage. Although electric regulator debugging ideal, because the action position limit switch is relatively fixed, the valve stem of the media in the valve in the operation of the scour and abrasion, can also lead to valve closed lax actuating the leakage phenomenon. The solution: the new debugging limit. Debugging methods: 1) Closing the valve manually ( Be sure to clearly acknowledged, and has absolute close) ; 2) With the strength to close the valve manually, will be subject to slightly wrest motionless; 3) Turn back again, Open valve direction) Half a circle; 4) And then adjust the limit. Q: electric control Industrial Valves leakage fault disposal of answer: 1, the executing agency zero setting is not correct, not reached the seated position of the valve. Solution: the new debug actuators, and regularly protects and proofreading. 7, the medium of scour, electric regulator aging actuating leakage electric regulator through certain time after debugging good running, because the valve cavitation and the media of scouring abrasion, valve core and valve seat initiation, inside the device aging, such as comprised, will manifest the electric regulating valve stroke slants big, electric regulating valve clearance is lax phenomenon, cause the electric control valve leakage quantity is big, with the passage of time, the electric control valve leakage phenomenon will be more and more serious.
