Abstract
The utility model relates to a quick-opening safety interlocking door for pressure containers. An existing door can be opened when the internal pressure of the container is high, which is unsafe. The utility model comprises a door central shaft, a rotary supporting seat, a handle, and a press claw provided with a guide device. The passage of the central shaft is provided with a self-locking shaft, the outer end of which is clamped into a handle seat, and the cap is arranged in a cavity in a central shaft seat. The corresponding surfaces of the central shaft and the self-locking shaft cap are respectively provided with a ratchet. The cavity is communicated with a pressure container. The self-locking shaft and an air vent are sealed through an elastic sealing layer. The exterior of the self-locking shaft cap is provided with a spring, and the handle seat is provided with a decorative cap. When the interior of the container has pressure, the door can not be opened. The use is safe and convenient.
Description
The utility model relates to a kind of safety door of pressurized container, particularly opens the safety interlocking door soon.
The quick opening structure of existing pressurized container, by the door body of doorframe, band seal ring, by the center axle bed be fixed on central shaft on the body, by bearing be contained on the central shaft in have the paw of the sealed doorframe of the rotary support of retaining pressing plate and screw, the handle set that is connected in the band handle on the rotary support, the band location that is contained in the rotary support periphery, guiding device to constitute.Owing to there is not self-locking structure, when not careful or pressure gauge took place to hinder admittedly as the operator, promptly rotatable handle can be opened door when container inner pressure is very high, and the goalkeeper who at this moment opens pressurized container has an accident.So it is very dangerous when using.
The utility model is at the deficiencies in the prior art, and what proposed a kind of pressurized container with self-locking device opens the safety interlocking door soon.
Task of the present utility model is to realize like this, the utility model be a kind of pressurized container open the safety interlocking door soon, comprise doorframe, the door body of band seal ring, be fixed on central shaft on the body by the center axle bed, by bearing be contained on the central shaft in the rotary support of retaining pressing plate is arranged, be connected in the handle set of the band handle on the rotary support, be contained in the band location of rotary support periphery, the paw of the sealed doorframe of guiding device, in the central passage of central shaft, the self-locking shaft that handle set is tangentially blocked in the outer end that axially can slide by a small margin is housed, in the cavity in the self-locking axle cap centering axle bed of self-locking shaft the inner, be respectively equipped with on central shaft and the self-locking axle cap face in correspondence with each other can be engaged ratchet, cavity in the axle bed of center is communicated with the door inner pressure vessel by vent, between self-locking axle cap and vent, be provided with elastic sealing layer, between self-locking axle cap and the central shaft passage Returnning spring be housed.Because of the cavity in the axle bed of center is communicated with in the inner pressure vessel with door by air bleed, (can transfer to 20KPa when vessel internal pressure power is higher, NBS is 27KPa) time, elastic sealing layer in the cavity is extrapolated with self-locking shaft by the self-locking axle cap, the ratchet of self-locking axle cap and central shaft is engaged can not to relatively rotate, and self-locking shaft blocks handle set, can not rotate between handle set and the central shaft, promptly door can not be opened, when vessel internal pressure power is normal pressure (being lower than 20KPa) by locked, elastic sealing layer retraction in the cavity, the self-locking axle cap returns self-locking shaft to original position again under the effect of Returnning spring, handle can rotate, and the gate can be opened.
The above-mentioned safety interlocking door of opening soon has and can be pushed away protruding trim by self-locking shaft at the outer surface of handle set.The function that shows locking is promptly arranged, decorating action is arranged again, also be convenient to install.
The utility model compared with prior art because the dress of the self-locking when having taked in the container pressure to be arranged system, door is not opened when in the container pressure being arranged, so convenient, safe and reliable when using.
Fig. 1 is the prior art constructions cross-sectional schematic.
Fig. 2 is a structure cross-sectional schematic of the present utility model.
Among Fig. 1, the quick opening structure of existing pressurized container, by the door body (13) of doorframe (15), band seal ring (14), by center axle bed (11) be fixed on central shaft (12) on the body (13), by bearing (5,7) be contained on the central shaft (12) in have retaining pressing plate (9) and screw (8) rotary support (10), be connected in the band handle (4) on the rotary support (10) handle set (6), be contained in paw (1) formation of the sealed doorframe (15) that the peripheral band location (3) of rotary support (10), lead (2) installs.
Fig. 2 is an embodiment of the present utility model.Among the figure, open the safety interlocking door soon for pressurized container, comprise doorframe (52), the door body (39) of band seal ring (51), be fixed on central shaft (42) on the body (39) by center axle bed (50), by bearing (40,41) be contained on the central shaft (42) in the rotary support (38) of retaining pressing plate (37) is arranged, be connected in the handle set (35) of the band handle (34) on the rotary support (38), be contained in the peripheral band location (33) of rotary support (38), the paw (31) of the sealed doorframe (52) of guiding (32) device, in the central passage of central shaft (42), the self-locking shaft (45) that handle set (35) are tangentially blocked in the outer end that axially can slide by a small margin is housed, in the cavity in self-locking axle cap (47) the centering axle bed (50) of self-locking shaft (45) the inner, be respectively equipped with on central shaft (42) and self-locking axle cap (47) face in correspondence with each other can be engaged ratchet (43,44), cavity in the center axle bed (50) is communicated with the door inner pressure vessel by vent (49), between self-locking axle cap (47) and vent (49),, between self-locking axle cap (47) and central shaft (45) passage Returnning spring (46) is housed with leather cup (48) sealing.Outer surface at handle set (35) has and can be pushed away protruding trim (36) by self-locking shaft (45)
