Description

The pressure vessel safety quick-opening device

Technical field

The utility model relates to a kind of high pressure deaeration machine, particularly the pressure vessel safety quick-opening device of high pressure deaeration machine.

Background technique

In the conventional construction, the quick-opening device of high pressure deaeration machine is the switching that realizes cover and tank body by the rotation cover, because the heavier cover of rotation needs bigger power, manually-operable is very difficult like this, other mechanism need be set drive cover, cause whole open device complex structure thus, cost is higher.In addition, decorative cover and jar enclose a relative rotation, can increase the liability fraying of seal element, reduce the operational safety of seal element, have shortened replacing and service cycle.

The model utility content

It is a kind of flexible, light that technical problem to be solved in the utility model is to provide, and can effectively reduce the pressure vessel safety quick-opening device of seal element wearing and tearing.

The technical solution of the utility model is as follows: a kind of pressure vessel safety quick-opening device, comprise tank body and cover, be provided with a jar circle in the end of tank body, the end of cover correspondingly is provided with decorative cover, its key is: be evenly distributed with first latch on the excircle of described decorative cover, the excircle of jar circle is provided with second latch, described second latch is identical with the first latch number and shape, the position is relative, described first, the outer race of second latch is equipped with outer rim, the end of this outer rim has can be to first, the 3rd latch that second latch is spacing, and be connected with gear handle by gear shaft on the outer rim, the gear of this gear handle the inner is meshed with tooth bar on the tank body.

Adopt above technological scheme, between cover and tank body, whirligig is housed, when the 3rd latch on the outer rim on decorative cover first latch and jar the circle on second latch time, the 3rd latch is spacing to first latch and second latch, a decorative cover and a jar circle are fitted tightly together, and cover is in closed condition; When pulling gear handle with hand, under the engagement of inner gear of gear handle and tank body upper rack, gear handle drives outer rim by gear shaft, make outer rim do circumferential movement along a decorative cover and a jar circle, stagger with first and second latch fully until the position of the 3rd latch, the 3rd latch unclamps the restriction to first, second latch at this moment, with pulling moving cover, under the effect of whirligig, cover can be opened.

The utility model is realized the switch of cover by rotating outer rim, and decorative cover is not done relative rotatablely moving with a jar circle like this, has effectively avoided in traditional door opening device because the heavier structure problem that cover brought of rotation.And, because decorative cover is not done relative rotation with a jar circle, reduced the liability fraying of seal element, improved the operational safety of seal element, prolonged replacing and service cycle.

In order to reach better effect, above-mentioned the 3rd latch is identical with the number and the shape of first, second latch.

Above-mentioned outer rim is provided with movable stop block, is equipped with on jar circle to cooperate spacing fixedly stop block with this activity stop block.Movable stop block matches with fixing stop block, to limit the angle of outer rim rotation, has improved the reliability of switch cover thus greatly.

For the rotation that makes outer rim is more flexible, light, on the excircle of above-mentioned jar of circle, bearing is installed by bearing support, this bearing cooperates with the outer rim rolling.

Beneficial effect: the utility model can be realized the switching of cover light, quickly, the wearing and tearing of seal element have been effectively reduced, prolonged the working life of seal element, have characteristics such as simple in structure, processing ease, flexibility and reliability, except that high pressure deaeration machine, also can be widely used on the various pressurized containers.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 6, be formed with a jar circle 3 in the end of tank body 1 open-mouth end, be evenly distributed with a plurality of second latches 6 on the excircle of this jar circle 3.The open-mouth end of described tank body 1 can be by cover 2 sealings, and this cover 2 is connected with tank body 1 by whirligig 16, is formed with decorative cover 4 at cover 2 near a jar end of circle 3, is embedded with seal ring 17 in the end face annular groove of decorative cover 4.On the excircle of described decorative cover 4, be evenly distributed with a plurality of first latch, 5, the first latches 5 with second latch, 6 numbers and shape is identical, the position is relative.At the peripheral suit outer rim 7 of first,

second latch

5,6, the end at these outer rim 7 two ends has can be identical with the number and the shape of first,

second latch

5,6 to spacing the 3rd latch 8, the three latches 8 of first, second latch 5,6.Fix by an end of screw and gear shaft 9 on the described outer rim 7, at the other end mounting teeth wheel handle 10 of gear shaft 9, the gear of these gear handle 10 the inners is meshed with the tooth bar 11 of tank body 1 outer wall setting.

From Fig. 1, Fig. 2, Fig. 4, shown in Figure 5, on outer rim 7, movable stop block 12 is arranged by screw, a jar circle is equipped with on 3 and cooperates spacing fixedly stop block 13 with this activity stop block 12.By screw a plurality of bearing supports 14 are arranged on the excircle of described jar of circle 3, by bolt bearing 15 is installed on each bearing support 14, this bearing 15 rolls with outer rim 7 and cooperates.
