Electric shower valve role: Add coating agent before feeding, after coating add water wash wall, to ensure that the kettle no hanging resin particles, improve the anti-stick spray effect, the material after washing the wall with water. Switch status: turn the valve clockwise, turn counterclockwise to open the valve (turn right, turn left), observe the rotating direction of the motor fan when it is not good to observe. Off detection are: proximity switch, travel switch. Open test: only the proximity switch. How it works: When the reducer output shaft rotation, it provides torque and tangential friction stem stem torque generated by the torque generated by the screw through the screw thrust is greater than the axial friction in the In non-extreme positions, the stem and sparger move linearly (at this time, the torque on the valve depends on the axial friction). When the stem moves to the open limit position, due to obstruction of the linear motion of the rod, the tangential friction torque can reach the maximum value and began to rotate (when the valve torque depends on the tangential friction), and then complete the clear kettle And painted walls work. Operation requirements: 1, Each tank equipped with two spray valve, symmetrical arrangement, in order to avoid the dead zone caused by cooling water pipes and stirrer, improve the effect of clear kettle. 2, in order to achieve a better spray effect, the steam pressure should be above 0.6MPa, coating liquid should be introduced into the steam through the centrifugal nozzle to prevent the coating liquid from flowing to the bottom of the tank. 3, closed position bandwidth 10mm, its opening is 175mm. Debugging requirements: 1, power line and control line connected, moving point observation screw steering, right-handed shut, left-handed open. 2, adjust the travel switch and proximity switch position, the valve manually switch to close with the limit (at this moment a significant increase in torque, such as continuing to rotate, the stem will rotate in place) on the basis of the valve stem to open the direction of movement 3-5mm , As the contact action position. 3, joint adjustment, press the knob to observe the valve action, the valve should be opened smoothly after the rotation, a little time, press the stop button, so as to avoid damage due to friction packing. Press the close button to observe whether the closed position is in the set position, and then give the valve through 1.6MPa high pressure water, check the closed position repeatedly, the valve should not leak. Duckbill valve Duckbill valve role: Add dispersant, after adding initiator, that is additive. Dazhong role of the tail valve: feeding (water), discharge (PVC). Working principle: Polymerization kettle electric discharge valve is an updated replacement of manual discharge valve, through the power control, the motor drives the worm and worm gear reducer and the rotation of the stem, so that the valve plunger up and down reciprocating linear motion, Through the travel switch to control the plunger moving distance, to achieve the valve open, valve off the purpose, play the role of material emissions. (Note: Whether on or off, there are proximity switches and travel switches, detecting valve start and stop, play a double protection, the other switch has 90 seconds time limit to protect the motor, so as to avoid the motor stuck in the middle position of the motor.) Construction: This valve consists of explosion-proof motor, reducer and valve and explosion-proof travel switch. Matters needing attention: 1, the valve in the polymerization reactor connection process, do not touch the explosion-proof travel switch, because its location is selected when the test valve is fixed, its movement and dislocation directly related to the work of the valve. 2, if the valve leakage phenomenon, the spring can be properly adjusted on the tightness of the nut, but remember not to screw too tight, in case the valve seal ring is too tight to hold the plunger, the motor load motor burned phenomenon . 3, if the valve is found to have internal leakage phenomenon, it may be because of the valve seal ring scratches and damage occurred, this time to replace the valve seal ring. 4, in the event of a sudden power outage, then the valve needs work, you can take the electric turn manual mode, the steps are: Turn the handle in the middle of the hand wheel, until the end of the twist, turn the handle in the end at the same time gently turn the hand Wheels, suddenly feel heavier hand wheel load, the conversion is completed, the direct use of manual wheel control valve work. 5, If you want to ensure long-term valve in good working condition, it is recommended to use the manufacturer during the annual overhaul of the valve for normal maintenance, that is, to the reducer plus grease, the valve decomposition cleaning, internal components check whether the abnormal situation. Common faults: 1, the limit switch feedback is not in place: a, the valve does not move; b, the proximity switch is shifted; c, DCS output relay failure; d, program problems; e, control loop failure; f, proximity switch is bad. 2, the valve does not move: a, contactor adhesion; b, power off; c, motor failure; d, electrical control loop failure; e, program problems; f, DCS cabinet DO relay failure; g, DCS cabinet control circuit insurance burst .
