The invention relates to the technical field of pressure containers, in particular to a lock-ring safety quick open blind plate. The blind plate comprises a high neck, a door cover and a door opening mechanism, wherein the door cover is provided with a snap-ring lock ring, an alarming screw rod and a safety interlocking mechanism; the opening of the snap-ring lock ring is provided with an insert block; and one end of a door assembly is connected with the high neck through a hinge shaft, while the other end is connected with the high neck through a safety bolt. The quick open blind plate has a multi-safety structure, so safety problems caused by the operation of the blind plate are completely avoided, and high safety and reliability are ensured in production process. Simultaneously, the quick open blind plate has excellent quick open function and the characteristics of safety, simple and convenient operation, and improvement on work efficiency.
Description
Technical field
The present invention relates to the pressure vessel technology field, especially a kind of lock-ring safety quick open blind plate.
Background technique
In a lot of pressurized containers that industries such as rock gas, oil, chemical industry are used, the blind plate that has a lot of needs often to open, traditional blind plate unlatching work is very loaded down with trivial details, labor intensive and time, along with constantly bringing forth new ideas of technology, some business research and develop the fast-opening blind product come into operation, and have obtained the acceptance and the approval in market.
Chang Yong fast-opening blind mainly is divided into four kinds of clamp band type, lock ring type, castellated and plug-in type in the market, and wherein lock ring type is praised highly most, is applied widely.But with regard to the lock ring type fast-opening blind, also there is the unfavorable problem of some safety techniques at present, wherein mainly shows two aspects:
(1) owing to operator's faulty operation, self does not possess the function of evading these faulty operations the fast-opening blind product, and the container that causes having pressurized gas throws open blind plate, and operator and peripheral personnel's life safety is constituted injury;
(2) the Safety function deficiency that exists owing to fast-opening blind self, when the gas of container did not also discharge fully, the door closure of blind plate also may be in the enable possition and be rushed out by overbottom pressure, to operator and peripheral personnel's life safety formation injury.
Summary of the invention
For the unfavorable deficiency of the safety technique that overcomes existing lock ring type fast-opening blind, the invention provides a kind of lock-ring safety quick open blind plate.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lock-ring safety quick open blind plate, comprise hub, door closure and door-opening mechanism, door closure is provided with clasp type lock ring, warning screw rod and safety interlocking mechanism, the opening of clasp type lock ring is provided with to be inserted, door assembly one end and hub couple together by hinge axis, and the other end couples together by safety pin and hub.
According to another embodiment of the invention, comprise that further door closure and crossbeam mechanism constitute the door assembly.
According to another embodiment of the invention, comprise that further safety interlocking mechanism is provided with ejector rod.
According to another embodiment of the invention, comprise that further the warning screw rod is provided with restraining groove.
According to another embodiment of the invention, comprise that further door-opening mechanism is provided with chain latch.
According to another embodiment of the invention, comprise that further safety pin is provided with spacing hole.
The invention has the beneficial effects as follows, this fast-opening blind has multi-safety structure, the omnibearing safety problem that occurs when avoiding operating blind plate, guaranteed that production process is medium-altitude safe and reliable, the outstanding function of opening soon that possesses fast-opening blind simultaneously, safe and easy and simple to handle, and be mainly reflected in the problem that has solved following two aspects:
(1) owing to operator's faulty operation, self does not possess the function of evading these faulty operations the fast-opening blind product, and the container that causes having pressurized gas throws open blind plate, and operator and peripheral personnel's life safety is constituted injury;
(2) the Safety function deficiency that exists owing to fast-opening blind self, when the gas of container did not also discharge fully, the door closure of blind plate also may be in the enable possition and be rushed out by overbottom pressure, to operator and peripheral personnel's life safety formation injury.

Fig. 3 is the structural representation of clasp type lock ring.
1. hinge axis among the figure, 2. hub, 3. door closure, 4. crossbeam mechanism, 5. safety interlocking mechanism, 6. the warning screw rod is 7. inserted, 8. clasp type lock ring, 9. door-opening mechanism, 10. safety pin, 11. ejector rods, 12. chain latches, 13. spacing holes, 14. restraining grooves.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As Fig. 1 is structural representation of the present invention, a kind of lock-ring safety quick open blind plate, comprise hub 2, door closure 3 and door-opening mechanism 9, door closure 3 is provided with clasp type lock ring 8, warning screw rod 6 and safety interlocking mechanism 5, the opening of clasp type lock ring 8 is provided with inserts 7, door assembly one end and hub 2 couple together by hinge axis 1, and the other end couples together by safety pin 10 and hub 2.Door closure 3 and crossbeam mechanism 4 constitute the door assembly.Safety interlocking mechanism 5 is provided with ejector rod 11.Warning screw rod 6 is provided with restraining groove 14.Door-opening mechanism 9 is provided with chain latch 12.Safety pin 10 is provided with spacing hole 13.
Crossbeam mechanism 4 is assembled into one by high strength screw and door closure 3, and door closure 3 and crossbeam mechanism 4 constitute the door assembly; Door assembly one end and hub 2 couple together by hinge axis 1; The door assembly can rotate around hinge axis 1, realizes the opening and closing of door; The other end at the door assembly couples together by safety pin 10 and hub 2 simultaneously.Being provided with seal ring between door assembly and the hub 2 seals.
The opening of clasp type lock ring 8 is filled in and is inserted 7, and at this moment clasp type lock ring 8 is in softened state; To insert 7 take away after, clasp type lock ring 8 just may be tightened up; 7 position screw rod 6 restrictions of being reported to the police of inserting are inserted 7 the time when warning screw rod 6 inserts and compresses, and insert 7 can't take away; Report to the police the simultaneously control of withdrawing from and be subjected to safety interlocking mechanism 5 of screw rod 6, when in the container compressed gas being arranged, the ejector rod 11 of safety interlocking mechanism 5 withstands the restraining groove 14 of warning screw rod 6, warning screw rod 6 can't withdraw from, after container inner pressure reduced and makes that the ejector rod 11 of safety interlocking mechanism 5 is shunk back fully, warning screw rod 6 just might be withdrawed from; The strutting and shrink by door-opening mechanism 9 and realize of clasp type lock ring 8, door-opening mechanism 9 is when opening clasp type lock ring 8, translation can take place in the position of door-opening mechanism 9 self, the chain latch 12 that will drive door-opening mechanism 9 during translation withdraws from the spacing hole 13 of the safety pin 10 of fast-opening blind, at this moment, if also have gas in the container, door closure 3 can be washed open by gas, but but limited, therefore can not produce injury operator and peripheral personnel by safety pin 10.
When fast-opening blind is closed, do not relate to safety problem, get final product according to normal stop.
