Technical field
The present invention relates to a kind of safety interlock, refer to particularly a kind of autoclave safety interlock device of quick actuating closure device.
Background technique
Fast opening type pressure container refers to the container with mutually nested quick-sealing locking device between the turnover end cap of container path or end socket and main body.Safety interlock device of quick actuating closure device is completely not discharge and just open a kind of safety interlock that quick operating valve has an accident with regard to booste operation or at container internal pressure because quick operating valve is not closed to specified position for preventing.
In recent years, adopt the autoclave of tooth-type structure to be widely used, have a large amount of new autoclaves of installing to come into operation every year, but the thing followed is the frequent generation of autoclave accident.From the nineties so far, almost have every year autoclave explosive accident to cause casualties.By the investigation and analysis of many autoclave accidents are learnt, the common ground of these accidents is all that the slippage of still tooth or damage cause blast, is the first cause that causes the slippage of still tooth and lack that effective quick operating valve interlock or interlock damage.
The interlock of current domestic fast opening type pressure container is of a great variety, although part interlock can reach the requirement of " fixed safe technology of pressure vessel supervision content regulation " the 3.20th article of regulation of TSGR0004-2009, but because autoclave generally uses in building material industry, production environment is severe, and the reasons such as still gate switch is frequent, operator's operation lack of standardization are easy to cause the damage of interlock.And the interlock that abroad some reliabilities are higher is because complex structure, manufacturing efficiency is low, expensive, maintenance cost is high etc., and reason is difficult to be widely applied.
Summary of the invention
Object of the present invention is exactly the deficiency that will solve above-mentioned background technology, and a kind of autoclave safety interlock device of quick actuating closure device is provided.
Technological scheme of the present invention is: a kind of autoclave safety interlock device of quick actuating closure device, is characterized in that: comprise mechanical interlock mechanism and self-locking mechanism, described mechanical interlock mechanism comprises: bearing, semi-circular plate, handle, transmission part, and limit position part,
