Fast-opening Blind

We are engaged in manufacturing and exporting excellent quality Fast-opening Blind to our valuable clients. The fast-opening blind is a machinery equipment which can quickly open or close, used for the pressure pipe or the circular opening of the pressure container. It usually consists of shell flange, cover, hook circle or yoke, sealing circle, security interlocking mechanism, open-close mechanism, tumbler and short-segment etc.

Sort of the Fast-opening Blind:
1 Paddlewheel fast-opening blind: It consists of coaxial unmarried print blind. The axial foreside blind is static; the ahead axial thrust provided by the paddlewheel rotating of the back plate through the screw transmission promotes the foreside blind to translation and press the sealing part; finally the blind is closed and tightened. No relative motion between the blind and sealing part is insured to avoid the attrition between the blind and sealing part; so the sealing part will not let out because of damage.
2 Locking ring fast-opening blind: It provides fast open-close structure for the receiver & launcher of level or vertical pipe. The design of the locking ring fast-opening blind is more secure and reliable than other fast-opening blinds because it can open any vertical or horizontal pressure container in short time. The fast-opening blinds with any size can be opened or closed in less than one minute without special instrument.
