The utility model is characterized in that: the inner wall of the cylindrical flange is provided with a notch; the blind plate is connected with the cylindrical flange through a door opening mechanism; the blind plate cover is provided with a lock ring groove and a groove; the lock ring is placed in the lock ring groove; a lip-shaped self-tightening type sealing ring is placed in the groove; the lip-shaped self-tightening type sealing ring is attached with the inner wall of the cylindrical flange; the door opening mechanism is provided with a handle; a safe locking mechanism comprises a force application rod, a safe plate and an alarm screw; the alarm screw is connected with the blind plate cover through a safety plate; and the force application rod is connected with the lock ring. The locking ring type quick opening blind plate has the following advantages: simple operation, good sealing performance, safe self-locking function, and reliable safety as the blind plate can not be opened by mis-operation at a pressurized state.
Description
Technical field:
The utility model relates to a kind of circular open that is used for pressure piping and pressurized container, can realize a kind of mechanical device of quick opening and closing.
Background technique:
The fast-opening blind that uses has a variety of forms at present, as faucet type, clamp band type and spile type or the like, the fast-opening blind of their these forms part that all comes with some shortcomings, the sealing effect that has is bad, the time of the opening and closing that have is long, the component required precision height that has, the processing trouble does not all reach desirable requirement.
Summary of the invention:
In order to address the above problem, the utility model provides a kind of lock ring type fast-opening blind, and it is simple to operate, and good seal performance has the safe self-locking function, and under band pressure situation, blind plate can not opened by misoperation, and is safe and reliable.
Technological scheme: the lock ring type fast-opening blind, it comprises shell flange and blind plate lid; Described shell flange inwall is provided with draw-in groove, the blind plate lid is connected with shell flange by door-opening mechanism, blind plate covers and is provided with lock ring groove and groove, lock ring is placed in the lock ring groove, the lip self-fastening ring is placed in the groove, and lip self-fastening ring and shell flange inwall are fitted, and door-opening mechanism is provided with handle; Safety locking mechanism comprises extension lever, guard plate and warning screw rod, and the warning screw rod is connected with the blind plate lid by guard plate, and extension lever is connected with lock ring.
The beneficial effects of the utility model, a kind of lock ring type fast-opening blind, it adopts the scalable lock ring structure of integrated type, various forms of fast-opening blinds more in the past, it has shortened the time of opening and closing greatly, only needs a human can easily finish in one minute less than the power of 200N; The self tightening lip seal configuration that it is unique makes the sealing safety and reliability; Its safe locking system has the safe self-locking function, and before equipment boosted, fast-opening blind and locking mechanism thereof can all be locked on the scheduled operation position, if be less than predetermined locked position, then equipment can not boost; After the equipment pressure release, before blind plate is opened, the interior pressure of container is all released, realize the secondary pressure release, avoided because the potential safety hazard that misoperation brought.
Description of drawings:
Fig. 1: be structural representation of the present utility model;
Fig. 2: be the A-A sectional view;
Fig. 3: be the B enlarged view.
Embodiment: as Figure 1-3, a kind of lock ring type fast-opening blind, shell flange 5 inwalls are provided with draw-in groove 9, blind plate lid 6 is connected with shell flange 5 by door-opening mechanism 4, blind plate lid 6 is provided with lock ring groove 7 and groove 13, lock ring 8 is placed in the lock ring groove 7, and lip self-fastening ring 12 is placed in the groove 13, and lip self-fastening ring 12 is fitted with shell flange 5 inwalls; Door-opening mechanism 4 is provided with handle 10, and safety locking mechanism 1 comprises extension lever 3, guard plate 2 and warning screw rod 11, and warning screw rod 11 is connected with blind plate lid 6 by guard plate 2, and extension lever 3 is connected with lock ring 8; When using, at first the pressure in the emptying device slowly rotates warning screw rod 11, presses when being zero the warning screw rod 11 of back-outing in confirming; If pressure release is not for the first time let out only, after the screw rod 11 of reporting to the police so screws out, can carry out the secondary pressure release, guarantee staff's safety; The warning screw rod 11 of back-outing takes off guard plate 2, pulls extension lever 3 counterclockwise, lock ring 8 is drawn in put in place, pulls handle 10, opens blind plate lid 6.
