Description

Fast opening type autoclave door closure safety interlocking
Technical field
The utility model relates to a kind of safety interlocking, relates in particular to a kind of fast opening type autoclave door closure safety interlocking.
Background technique
Autoclave claims steam-cured still again, is a kind of bulky, large pressurized vessel that weight is heavier.The autoclave of building material industry use at present, its still door closure safety interlocking adopts the traction armature of electromagnetism linking mechanism to drag safety pin more, and making kettle flange and still door closure chain is one, promptly realizes safety interlocking with safety pin and electromagnetism linking mechanism.There is following deficiency in this device under existence conditions: one, and during autoclave work, make traction armature in running order for a long time, and be installed on the kettle flange of high temperature, it is short that traction armature Environmental Conditions worsens the life-span; Its two because traction armature tractive effort limits, diameter of safety pin is difficult for excessive, is generally 12 millimeters, in the operation, the still door closure opens and closes corner and inevitably causes error, more easily makes safety pin crooked and cut off.
The model utility content
The purpose of this utility model is to provide a kind of fast opening type autoclave door closure safety interlocking of long service life.
For achieving the above object, the utility model provides a kind of fast opening type autoclave door closure safety interlocking, the safety pin that comprises the pin-and-hole that is positioned at the kettle flange, the upper end of described kettle flange is equipped with cylinder block by fastening piece, the upper end of described cylinder block is equipped with cylinder head, the middle part of described cylinder head is provided with the cylinder intake exhaust nozzle, described cylinder intake exhaust nozzle is connected with the steam tube road junction of autoclave by pipeline, the upper end of described safety pin is passed described fastening piece and is stretched in the described cylinder block, in the described cylinder block piston is installed, the upper end of described safety pin is connected with the bottom surface of described piston, on the safety pin between described piston and the described fastening piece, be with spring, the upper end of described spring withstands on the bottom surface of piston, and the lower end of described spring withstands on the described fastening piece.
Fast opening type autoclave door closure safety interlocking of the present utility model, described safety pin is cylindrical, its diameter is 30mm.
Fast opening type autoclave door closure safety interlocking of the present utility model is replaced by cylinder with the electromagnetism linking mechanism of existing control safety pin, utilize the high pressure steam in the autoclave to promote the interior piston of cylinder, and then the descending locking autoclave of promotion safety pin door closure, after the high pressure steam in the cylinder is discharged, be positioned at cylinder spring make the up autoclave door closure of opening of safety pin, thereby the electromagnetism linking mechanism that has overcome existing control safety pin is in short defective of following life-span of high temperature and high pressure environment, the working life of having improved fast opening type autoclave door closure safety interlocking.
In addition, because fast opening type autoclave door closure safety interlocking of the present utility model is not established traction armature, the diameter dimension of safety pin can increase slightly to 30mm, in the opening and closing operations of still door closure, be difficult for the bending distortion, thus the working life of further having improved fast opening type autoclave door closure safety interlocking.
Description of drawings
Fig. 1 is the structure sectional view of the fast opening type autoclave door closure safety interlocking of model utility.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
With reference to shown in Figure 1, the fast opening type autoclave door closure safety interlocking of present embodiment comprises the columniform safety pin 9 of the pin-and-hole 2a that is positioned at kettle flange 2, its diameter is 30mm, the upper end of kettle flange 2 is installed with cylinder block 5 by fastening piece 3, the upper end of cylinder block 5 is installed with cylinder head 4, the middle part of cylinder head 4 is equipped with cylinder intake exhaust nozzle 6, cylinder intake exhaust nozzle 6 is connected with the steam tube road junction 11 of autoclave by pipeline 10, the upper end of safety pin 9 is passed fastening piece 3 and is stretched in the cylinder block 5, piston 7 is installed in the cylinder block 5, the bottom surface of the upper end of safety pin 9 and piston 7 is connected and fixed, on the safety pin 9 between piston 7 and the fastening piece 3, be with spring 8, the upper end of spring 8 withstands on the bottom surface of piston 7, and the lower end of spring 8 withstands on the fastening piece 3.
Under autoclave is in atmospheric pressure state, the restoring force of spring 8 piston 7 of upspringing affects safety pin 9 to top dead center, the lower end of safety pin 9 then rises to the pin-and-hole 2a of kettle flange 2 from the lockhole 1a that is positioned at still door closure 1, still door closure 1 separates with kettle flange 2, still door closure 1 can be realized along rotating counterclockwise operation at this moment, makes it to open or close the still door closure.Otherwise, after still door closure 1 is closed, when in the kettle of autoclave, sending into steam, high pressure steam in the kettle enters cylinder block 4 epicoeles by pipeline 10, cylinder intake exhaust nozzle 6 successively, and then promote the lower end that piston 7 moved down and drove safety pin 9 and come downwards in the lockhole 1a of still door closure 1, thereby with still door closure 1 and kettle flange 2 chain be one.At this moment, even if there is the external force effect still door closure 1 can not rotating opening, realize having press with safety interlocking synchronous.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in related domain make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
