Description
Technical field
The invention belongs to vessel fabrication field, particularly, the present invention relates to a kind of container cover seal locking mechanism.
Background technology
Application widely for container (comprising drier container, Chinese medicine extracting tank, reactor, mixer etc.).Conventional container lid and container, be bolted vessel flange and lid flange closure.Inefficiency, pass lid of uncapping is wasted time and energy, and is unfavorable for Automated condtrol.
In addition, angle-style or grooved clamp ring inclined-plane catch gear is also had, this closing means, owing to will clamp ring be enclosed within vessel flange and lid flange, have to open some gap on vessel flange and lid flange, this just destroys the globality of flange, weakens their intensity.And clamp ring is the important document of connecting container flange and lid flange, because of intensity need also will to do enough thick enough wide.Therefore angle-style or grooved catch gear connect can Automated condtrol than bolt, but complex structure is heavy, and mechanical processing process is complicated, is not easy again the conformability ensureing each gap inclined-plane.
Summary of the invention
The object of the invention is to, provide a kind of container cover seal locking mechanism, this mechanism structure is simple, and dependable performance, easily processes, and controls manually or automatically all to facilitate enforcement.
For achieving the above object, present invention employs following technical scheme:
A kind of container cover seal locking mechanism, described mechanism comprises vessel flange 1 and lid flange 2, the internal orifice 21 of described vessel flange 1 arranges the first groove 15, described lid flange 2 arranges the second groove 19 with the first groove 15 correspondence position, described first groove 15 and the second groove 19 form the epitrochoidal chamber that is held piston ring 3, the built-in piston ring 3 of described epitrochoidal chamber, described piston ring 3 is disconnected by piston ring gap 16 on two terminations being formed and respectively arranges a piston ring journal stirrup 4, described piston ring journal stirrup 4 connects a piston ring folding driven unit, described piston ring folding driven unit is for driving the folding of piston ring gap 16, thus control the increase of piston ring 3 diameter or reduce.
Further, described piston ring folding driven unit comprises and turns core shift fork 6, the described two ends turning core shift fork 6 are flexibly connected a hinge-rod 5 respectively, described hinge-rod 5 is also movably connected with piston ring journal stirrup 4, the described centre turning core shift fork 6 fixedly wears anchor shaft 14, described anchor shaft 14 one end is fixed on lid flange 2, other end connecting handle 7.
Further, described piston ring folding driven unit also comprises pressing fork rack 10, and described pressing fork rack 10 is for fixedly turning core shift fork 6.
Again further, described handle 7 arranges locating dowel pin 9, described pressing fork rack 10 corresponds to locating dowel pin 9 and knock hole 8 is set.
The core shift fork 6 that turns of the present invention is all flexibly connected by bearing pin 11 with piston ring journal stirrup 4 with hinge-rod 5, hinge-rod 5.
The medial surface of the second groove 19 of the present invention comprises groove inclined-plane 18 and spigot surface 17; When container cover is in open mode, described groove inclined-plane 18 matches with the lower inclined plane 20 of piston ring 3, and described spigot surface 17 matches with the inclined-plane, side of piston ring 3; When container cover is in closed state, the opposite side inclined-plane of piston ring 3 and the inclined working 12 of the first groove 15 match.
Preferably, the inclined working 12 of described first groove 15 and sealing surface 22 bevel 5 ~ 15 degree.Because inclined working 12 and sealing surface 22 are angled.Therefore, the side-fit of this inclined working and piston ring, piston ring 3 rise into time produce axial pressing force, namely perpendicular to the power of sealing surface, thus container cover is closed to container.
Preferably, 55 ~ 75 degree of oblique angles in groove inclined-plane 18 and sealing surface 22 one-tenth of described second groove 19, can stop coming off of piston ring 3.
Preferably, described first groove 15 is in order to type groove, and described second groove 19 is angle-style groove.
Preferably, between described vessel flange 1 and the sealing surface both lid flange 2 22, elastic seal ring 13 is set.
Spigot surface of the present invention 17 pairs of piston rings 3 play the guiding role.
The core shift fork 6 that turns of the present invention is External Force Acting hinges, and External Force Acting, on handle, transmits torque to hinge-rod by turning core shift fork, then is delivered to piston ring journal stirrup, can increase or reduce the distance of piston ring 3 gap 16, thus forces the diameter of piston ring 3 increase or reduce.After the diameter of piston ring 3 increases, under the combined action of spigot surface 17 and inclined working 12, piston ring 3 and inclined-plane 12 produce the axial pressing force perpendicular to sealing surface, elastic seal ring 13 is out of shape, thus makes container closure.
In the present invention, the outside diameter of piston ring 3 is less than the internal diameter of the internal orifice 21 of vessel flange 1.
The main force part of container cover seal locking mechanism of the present invention is on vessel flange 1 and lid flange 2.Therefore compressive strength is larger.And work piece---piston ring 3, be stressed and be not subject to pulling force, pressure transmission power is between vessel flange 1 and lid flange 2, what make can be smaller, make the elastic force suffered by the increase of its diameter also little, thus its control mechanism---it is simply small and exquisite that the hinge in piston ring folding driven unit, shift fork can do thereupon.But, because the section of the type groove on vessel flange and the angle-style groove on lid flange and piston ring 3 is the oblique quadrangle form of geometry, determine positive pressure or the negative pressure of container after closing, act predominantly on vessel flange and lid flange, and control mechanism---the hinge in piston ring folding driven unit, shift fork are not quite stressed, add the setting of locating dowel pin and knock hole, make whole closing means reliable.
