A mechanical device for opening and closing a pressure vessel, generally composed of a simplified Chinese version, a head benefit, a chain, a joint, a safety interlocking mechanism, an opening mechanism, a rotating bone and other components. According to the connection between the cylinder body, the ring or the card, and the head cover, the quick-opening plate is divided into the following typical structures: the press type, the cross-mirror type, the lock ring type, the plug-in type, etc. (see Figures 1 to 8.
3.1 Bottom-type quick-opening plate
A quick-opening self-opening plate that can be quickly opened or closed by disengaging or engaging the groove on the hook. The missing type quick-opening self-opening plate is divided into two types: the body type (when the hook and the body flange are integrated) and the split type (the structure and connection diagram are shown in Figures [and ≤ ). 3.2 Clamp-type quick-open plate
A quick-open plate that can be quickly opened or closed by the looseness or tightness of the clamp. The clamp is usually divided into two or three parts (its structure and connection diagram are shown in Figure 2 and Figure 6).
