Abstract
The utility model relates to a device for quickly opening a flange lock. A positioning block 1 and a pressing block 2 are hinged by a pivot 3. A positioning lock shaft 4 is inserted in the overlapping part of two clamps, and bayonets are clamped at the outer edges of two flanges. Screw-bolts 7 on the pressing block 2 are screwed, which enables the pressing block 2 to press to the flanges and be locked. When the flanges are opened, the positioning lock shaft 4 is pumped down. The pressing block 2 circles the pivot 3 to rotate, which gets rid of the locking force of the screw-bolts 7 for the flanges. The utility model has the advantages of simple structure, convenient operation, quick opening, and big locking force. The device for quickly opening a flange lock can be made into various specifications. The device for quickly opening a flange lock can be widely used at the combining and sealing situations where pressure vessels are connected with covers and pipelines and need to be opened.
Description
The utility model relates to a kind of flange coupling arrangement, the locking device at the sealed faying face place of opening especially for need.
Existing flange coupling arrangement mostly is bolton and connects, and this structure coupling mechanism force is big and even, but it is bigger to install and remove cumbersome, time-consuming labor intensity.
CN85100290 disclosed " self-tightening device on pressure vessel with brazier head screw " adopts junction of the edges of two sheets of paper flat screw to connect container cap and flange, its compact structure, and easy disassembling, but need to adopt special sealing configuration, and its processing technology complexity, coupling mechanism force is limited.
Internal thread outside ZL93219515.6 disclosed " thread engagement is opened flange soon " has on the edge of container and top cover connects by screw threads for fastening, and structure is also compact, but coupling mechanism force is limited, and the screw thread processing cost is higher; Need large size machine tool processing, it is convenient inadequately to open, in the sealing than some trouble.
The purpose of this utility model provides a kind of close, open convenience, flange locking device efficiently.It is simple in structure, and is easy to process, and purposes is wide.
The purpose of this utility model has been achieved in that a flute profile clamp, is formed through hinge and the connection of dismountable location lock shaft by positioning block and compact heap, at compact heap bayonet socket position bolt is housed.Alignment pin can be extracted out.
Hinge is positioned at positioning block one side, and alignment pin is positioned at compact heap one side.
The bolt on the compact heap and the bayonet socket of positioning block are inwardly exerted pressure from the outer side surface of two flange plate, with flange plate and sealing gasket locking.
If extract the location lock shaft out, compact heap only depends on hinge to be connected and can rotate outside promotion positioning block mutually with positioning block has promptly removed the coupling mechanism force of clamp to flange plate.
Between bolt and the compact heap locking nut is housed, bolt to flange plate exert pressure screw after, turn locking nut again forms self-locking, descends with the anti-loosening coupling mechanism force that makes.
The utlity model has advantage simple in structure, compact, that processing cost is low, unlatching is quick, locking is convenient and coupling mechanism force is big, purposes is wide, for general flange sealing configuration, all can use as the sealing position of the frequent unlatchings of need such as pressurized container is connected with lid, pipeline.
The utility model can be made the standard piece of all size and select to use, can or be fastenedly connected on flange plate outer side edge the welding of positioning block bayonet socket in use and form one, when needing sealing locking, compact heap is pushed to, the insertion alignment pin turns bolt and locking nut gets final product, when unclamping, extract alignment pin out, can release compact heap easily.Remove the sealed attachment of flange.
Positioning block of the present utility model also can not be welded on the flange plate promptly with, promptly tear open.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model uses schematic representation.
Fig. 3 is the schematic top plan view of Fig. 2.
Below in conjunction with description of drawings embodiment of the present utility model.
By shown in Figure 1, the utility model positioning block 1 and compact heap 2 are the right angle type plate structure, each other through hinge 3 hinged becoming one, hinge 8 is arranged near on the position of positioning block 1 below, hinge 3 positions are moved on also can be suitably, on the overlapping part near the positioning block 1 of compact heap one side and compact heap 2 on the hinge 3, have a pin-and-hole in addition alignment pin 4 is housed, if alignment pin is placed on positioning block one side, opposite side rotates to flange plate in the time of then the space increasing of two card roots and flange plate cylindrical should being rotated conveniently to compress card 2, hinge 3 and alignment pin 4 fore-and-aft distances with bigger be good, fixing between compact heap 2 and the positioning block 1 by hinge 3 and 4 two of alignment pin, constitute a groove shaped clamp.The utility model also can be made the clamp structure of arcuate openings.There is a tapped through hole at bayonet socket 5 positions at compact heap 2, are rotary with the bolt 7 that has locking nut 6.Bayonet socket 8 positions of positioning block 1 are a plane, can carve the cruciate flower groove on the plane, to increase the friction that contacts with flange plate.
During use, compact heap 2 pushed to make bayonet socket 5 parallel with positioning block bayonet socket 8, insert alignment pin 4, make compact heap 2 and positioning block 1 relative fixed, push two bayonet sockets the edge, junction of two flange plate 9,10 to, turn bolt 7 makes its top to flange plate 9, and bayonet socket 8 and bolt 7 compress from both sides with two flanges and sealing gasket positioning block 13, after coupling mechanism force is suitable, screws locking nut again and form self-locking.
Fig. 2 and for example in use, for making lid and container folding with convenience, just adorns a hinge 11 sometimes at the edge of container, make cover 12 and can upper and lowerly easily lift, and close when locking, and all the other positions are locked with the utility model respectively.
As Fig. 3, the quantity that the utility model is used on the flange plate can be selected according to the size of flange plate and the requirement of junction plane sealing.Be generally symmetry locking and arrange that the bolt Point of Strength generally apart from flange plate excircle 20-30 millimeter, is compared with the standard welded flange, save about the about 30%-60% of material, in can being widely used in, being tightly connected of low pressure vessel etc.
