pvc key valve principle and maintenance

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. Today's Focus: • Analysis and Outlook of Domestic Mold Steel Market • Demand for Construction Steel in China Will Increase • Startup Requirements for Environmental Protection and Energy Conservation • "National Standard for Ceramic Tile" Switch Status: Turn the valve clockwise and turn it counterclockwise (Right-hand closed, left-hand open.When it is not good to observe, you can observe the motor fan blade rotation direction). 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. Note: ① valve in the polymerization reactor connection process, do not touch the explosion-proof travel switch, because it is the location of the selected test valve fixed, and its movement and dislocation directly related to the work of the valve. ② If you find the valve leakage phenomenon may be appropriate to adjust the tightness of the nut on the spring, but remember not to screw too tight, to prevent the valve seal ring too tightly hold the plunger, the motor load appears motor burn phenomenon. ③ If the valve is found to have internal leakage phenomenon, it may be because of the valve seal ring scratch and damage occurred, then the valve seal must be replaced. ④ In the event of a sudden power supply interruption, then the valve needs to work again, you can take the electric turn manual mode, the steps are: Turn the handle in the middle of the handwheel until it reaches the end of the screwdriver, turn the hand wheel , Feel sudden increase in hand wheel load, then the conversion is complete, direct control of the manual wheel 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 and cleaning, check the internal parts with or without exception. · China Building Materials Network - Building Materials, a little pass ranked top three, disdain for peer · Wind and rain together for five years · Excellent Building Materials Enterprise Webcast common faults: 1, the limit switch feedback is not in place: a, the valve does not move; b, proximity switch ; C, DCS output relay failure; d, program problems; e, control loop failure; f, close to the 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
