Quick actuated door with sector seizing-up plate

Abstract

A sectorial quickly actuated gate consists of a seal cap, a flange, a ratchet, sectorial pieces, spacers, a press ring, fasteners, sectorial piece resetting device and holder. The ratchet is arranged between the flange and the press ring axially. Sectorial pieces and spacers are arranged radiatively and in periphery of the ratchet. The spacers are fixed with the fasteners. Annular slot are cut on the inner wall of the holder in the places matched with the sectorial pieces. The gate has thinner body with simple structure and can be actuated easily and quickly.

Description

technical field [0001] The invention relates to a quick-opening door pressure vessel. In particular, it relates to a fan-shaped clip-type quick-opening door for a pressure vessel. It belongs to the technical field of pressure vessels. Background technique [0002] Quick-opening pressure vessel refers to a pressure vessel that can complete the opening or closing process after a continuous action of the vessel end cap or locking member, without the need to tighten the fastening bolts one by one. Its quick-opening door is for the materials in the pressure vessel to enter and exit. Fast-opening containers with higher pressure usually adopt tooth-sparing meshing structure. It mainly has the following deficiencies: [0003] 1. Since the quick-opening door and the clamp body must be processed into teeth, for this reason, only half of the circumference of the quick-opening door and the clamp body can be used to bear the force, and the stress state is poor. In order to ensure the...

Problems solved by technology

[0003] 1. Since the quick-opening door and the clamp body must be processed into teeth, for this reason, only half of the circumference of the quick-opening door and the clamp body can be used to bear the force, and the stress state is poor. In order to ensure the quick-opening door and The strength of the pressure components of the clamp body can only be achieved by increasing the overall axial thickness of the quick-opening door and the clamp body

[0004] 2. The overall axial thickness of the quick-opening door and the clamp body is thick, and the door hinges must be rotated in pairs to rotate. The structure of the door hinges is complex and heavy, and it is difficult to align the teeth of the quick-opening door with the teeth of the clamp body when the door is closed. Middle meshing, the opening and closing of the quick opening door is very inconvenient

[0005] 3. Due to the large friction coefficient of the rubber material of the sealing ring and the pre-compression, the sealing ring and the quick-opening door have relative rotation friction when the quick-opening door is opened and closed, and it is very laborious to rotate the quick-opening door. Driven by cylinder and motor, in addition, the sealing ring is seriously worn and the service life is short
