Open and Close Method of Closure

1. Opening Procedures

Open the vent valve and drain valve of the installation vessel of blind plate to decrease the inner pressure to zero. Special Tip: Not allow open it under pressure. Open the vent valve and drain valve of the installation vessel of blind plate to decrease the inner pressure to zero. Screw the core vent; take off the loose-proof pallet. Rotate the screw mandrel by special wrench according to the direction marked on switch to enlarge gradually the inner diameter of the three pedals locking until it is larger than the outer diameter of the blind cover and stop. At this time, the clamp collar is apart from the base and cover of blind. Pull the handle to the right side and open the blind plate.

2.  Closing Procedures

Clear up thoroughly the dirties in sealing surface, seal groove and clamp collar up and down, and paint grease to prevent from rust. Close and push tightly the blind plate. Rotate the screw mandrel anticlockwise by special wrench and compact the blind cover .Fit over the groove hole of the loose-proof pallet and position, screw down the core vent (Pay attention, the sealing ring shall not be dropped)

Ⅳ Safety Operation and maintenance

(1)When weld the blind plate and the barrel, the current shall not be too large. Pay attention that do not make the blind plate over heated to avoid distortion.

(2)People who use the blind plate must know the structure and the operation procedure well.

(3)Do open the vent valve before the blind cover is opened. Operation can be carried out only when the inner pressure of the pig receiver & launcher decreases to zero.

(4)Before adding pressure inside the receiver & launcher, do install the loose pallet well. And then it can be put into operation.

(5 )When the receiver & launcher is put into application, it is not allowed to knock or impact any main compression parts.

(6)The driving mechanism and the screw mandrel locking device of blind plate must be painted grease often to prevent from rust. And the appearance must be kept complete, bright and clean often.

(7)Inspect the main compression parts (e.g. blind cover, external surface of barrel) of blind plate regularly. Check causes for serious corrosion or cracks and process properly.

(8)Wash, inspect and paint grease on the sealing ring and the sealing groove after use in case they can not be sealed while operation.

(9)  Keep paint for closure's outer surface brightly integrity.

(10) Install the explosion proof switch of the fast opening blind plate with the goods in the blind plate(fix only the blot), when fast opening blind plate to open in place travel switch start. Install travel switch connected cable transmission, the travel switch is DPDT, can provide instant switch signal, voltage rating of 380V, current 2A, explosion-proof grade EXDIIBT4,protection levels to meet IP65. (The specific installation instructions see FIG.1)
