Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.
Embodiment one
As shown in Figures 1 and 2, a kind of seal of vessel end cap subdivision ring type quick-opening device is located at the handle hole place of container, structure specifically comprises shell flange 12, seal ring 11, flat cover 10, many group guide mechanisms and organizes subdivision pawl mechanism more;
Described shell flange 12 is fixed on the handle hole place of container, can be directly welded in one end of cylindrical shell, also can be on container, to install one section of adapter additional weld shell flange 12 again.Shell flange 12 comprises the endoporus with step; Flat cover 10 is located at the step place of endoporus, is provided with seal ring 11 between flange 12 and flat cover 10.Seal ring 11 can be arranged at end face.
Concrete in this example, described flat cover 10 is variable-diameter structure, and the shaft shoulder place of reducing contacts with the step of the endoporus of shell flange 12; Path part stretch in the endoporus of the minor diameter of shell flange 12, between seal ring 11 is set.
Flat cover 10 is separated with unlatching with flange 12 press seal by multiple subdivision pawl mechanism controls; Concrete many groups subdivision pawl mechanism is radial uniform along flat cover 10 center circumference, and flat cover 10 axle center place is provided with fixed axle sleeve 6 and rotary sleeve 5, and rotary sleeve 5 is articulated with on fixed axle sleeve 6; Can rotate along fixed axle sleeve 6.Each subdivision pawl mechanism comprises connecting rod 3 and subdivision ring block 7, and it is hinged that connecting rod 3 one end and rotary sleeve 5 pass through the first bearing pin 4, and the other end and subdivision ring block 7 are by the second hinge; Articulating point i.e. each first bearing pin 4 of each connecting rod 3 and rotary sleeve 5 are uniform along rotary sleeve 5 axle center circumference, are particularly articulated with on the periphery of rotary sleeve 5.
Many groups guide mechanism respectively correspondence is located on each subdivision ring block 7, described guide mechanism comprises the slide block 8 being located at (in Fig. 1 lower position) inside subdivision ring block 7 and the slide-and-guide groove 9 being located at flat cover 10 corresponding position, and slide block 8 slides in slide-and-guide groove 9.Rotary sleeve 5 rotarily drives connecting rod 3 and swings, each subdivision ring block 7 is driven to move radially along guide mechanism, particularly slide block 8 slides in slide-and-guide groove 9, shift out in groove by shell flange 12 or move into, subdivision pawl mechanism is closed or open, and then controls being separated with unlatching with flange 12 press seal of flat cover 10.
Here, rotary sleeve 5, connecting rod 3, subdivision ring block 7 (comprising slide block 8 and slide-and-guide groove 9), constitute a simple kink four bar linkage, can be regarded as typical crank slider arrangement, rotary sleeve 5 is crank, connecting rod 3 is connecting rod, and subdivision ring block 7 is slide block.
Meanwhile, one of the contact outside surface of subdivision ring block 7 and groove is wedge surface.Here outside refers to top in Fig. 1, and corresponding and inner side has been exactly below, namely in container.Wherein situation is the outer surface of subdivision ring block 7 is wedge surfaces, and namely downward-sloping by axle center outward direction, namely large diameter part thickness is in the part of minor diameter; Like this at subdivision ring block 7 in migration process in groove, under the effect of wedge surface, flat cover 10 can container inside direction compress, hermetically closing.Another kind of situation is that the minor diameter of groove upper surface (referred to herein as outer surface) is downward-sloping to major diameter direction, and namely large diameter part recess width is in the part recess width of minor diameter; Like this at subdivision ring block 7 in migration process in groove, under the effect of wedge surface, flat cover 10 can container inside direction compress, hermetically closing.
In this example, in order to ensure safe operation, described subdivision pawl mechanism is also provided with locking safeguarding mechanism, locks quick-opening device when subdivision pawl mechanism closes.Described locking safeguarding mechanism comprises perforate at least one connecting rod 3 located therein and safety pin 14, and the perforate of the corresponding position on flat cover 10 is inserted in safety pin 14 perforate of inserting on connecting rod 3 again.To ensure the stability of working state, meanwhile, before sky container internal pressure has been let out, forbid to extract safety pin 14.The perforate of the perforate on connecting rod 3 here and the corresponding position on flat cover 10 can be many groups, more than the quantity of safety pin 14, also can equal the quantity of safety pin 14, at least insert a safety pin 14 during use by quantitative requirement.
In this example, in order to easy to operate, described flat cover 10 is provided with pressure relief means thereon.Particularly on flat cover 10, arrange pressure relief vent, a pressure relief valve is equipped with at pressure relief vent place, or is provided with plug by screw thread in pressure relief vent.
Using method:
Check whether chamber container inner pressure has been let out, and opens the pressure relief means thereon on flat cover 10, as opened pressure relief valve or outwards rotating plug.Object ensures the pressure in container fully to lower, and could quick operating valve be opened, to ensure safety again.
Under subdivision pawl mechanism closes situation, extract safety pin 14, give rotary sleeve 5 external force by special instrument, rotary sleeve 5 is rotated, and rotary sleeve 5 rotarily drives connecting rod 3 and swings, each subdivision ring block 7 is driven to move radially along guide mechanism, particularly slide block 8 slides in slide-and-guide groove 9, shifts out by the groove of shell flange 12, realizes subdivision ring block 7 and exits in the groove of shell flange 12, by external force, flat cover 10 is taken out from shell flange 12.Otherwise, realize installing and sealing.
Embodiment two
A kind of natural gas filter, it adopts above-mentioned seal of vessel end cap subdivision ring type quick-opening device, and a STH of natural gas filter cylindrical shell 13 is described handle hole.
Owing to have employed technique scheme, tool of the present invention has the following advantages and effect:
1, can realize the switching motion of seal of vessel end cap effectively, safely, realize the worry core as quick-replaceable natural gas filter, labor intensity is low.
2, structure compact simple, take up room little.
3, change concrete physical dimension, different working flow demands can be adapted to.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
