Abstract
The utility model relates to a movable pipe orifice sealing device, belonging to the special tools for temporary sealing of pipelines. The sealing device comprises a nut sleeve with a handle, a four link rod expansion mechanism which is controlled by the sealing device and comprises two toothed blocks, four supporting arms and screws, a sealing cover, and a sealing ring. The handle is turned, the four link rod mechanism with two toothed blocks is expanded, fastens the pipe wall, the four link rod mechanism presses the sealing cover with the sealing ring on the pipe orifice, and the pipe orifice is sealed. The utility model has the advantages of convenient sealing and disassembly, reuse, low labor intensity, and high work efficiency.
Description
The utility model belongs to the instrument of the shutoff mouth of pipe.
When laying various pipeline, whether leak etc. in order to prevent that foreign matter from entering in the pipe or detecting pipeline, need in work progress, pipeline one end temporarily be sealed.Usually a kind of way that adopts is directly to be welded in the mouth of pipe with sheet metal at present; Another kind method is at several protrusions with holes of mouth of pipe outer wall welding, and the dome that will be lined with cushion rubber again uses bolton on the mouth of pipe.This dual mode all needs to carry out provisional welding on body, and finishes the dismounting of use back, and this not only causes man power and material's waste, and easily body is caused damage.
The purpose of this utility model is to provide a kind of light and flexible, time saving and energy saving, the movable ferrule instrument that can reuse and pipeline itself do not have is damaged for pipeline construction department.
Its solution is: in the toothed instrument insertion tube of an end with closure one end, utilize the spiral pulling force that teeth are opened and bite inner tube wall, sealing cover also props up the mouth of pipe simultaneously, thereby reaches sealing purpose.
The utility model is to realize above-mentioned purpose like this:
Movable ferrule device is by two tooth pieces (1,1 '), a pair of isometric preceding support arm (3,3 '), a pair of isometric back support arm (2,2 '), screw rod (4), connecting sleeve (5), pressure spring (6), sealing cover (7), seal ring (8), ut socket (9), handle (10), seal ring (11) and five coupling shafts (0

2, 0
2', 0
3, 0
3') constitute; One end of support arm after two (2,2 ') and screw rod (4) coupling shaft (0
1) connect, an end of two preceding support arms (3,3 ') is used coupling shaft (0 respectively
2, 0
2') be connected and be enclosed within on two of screw rod (4) is gone up and become to be slidingly matched connecting sleeve (5) picks up the ears, the other end of two pairs of back and front supporting arms (2-3,2 '-3 ') and two tooth pieces (1,1 ') are used two coupling shafts (0 respectively
3, 0
3') connect, at coupling shaft (0
1) and connecting sleeve (5) between screw rod (4) on be set with pressure spring (6), the sealing cover (7) that is embedded with seal ring (8) is enclosed within on the screw rod (4) by mesopore, in order to prevent and mouth of pipe dislocation that the sealing cover edge can be rolled into (or welding) guard ring vertical with lid.Seal ring (11) is enclosed within screw rod (4) and goes up and paste mutually with sealing cover, and ut socket (9) is twisted and is connected on the screw rod (4), and handle (10) is serially connected in ut socket (9) end in detachable mode.
In order to guarantee that the tooth piece can sting tight tube wall, the face that the tooth piece contacts with inner-walls of duct is arc surface and has helical teeth that the curvature of its arc surface is identical with inner-walls of duct curvature.And preferably use higher alloyed steel of hardness or high carbon steel to manufacture the tooth piece.Screw rod and nut should be processed into the buttress thread form that bears unidirectional axial force.According to the difference of pipe bore, the utility model can be made into the series product of plurality of specifications.
Use and working principle:
According to above structure, back and front supporting arm and connecting sleeve are coupling, and constitute the pentagon with quadratic crank mechanism, and under the effect of pressure spring, the bidentate piece has minimum separable.During use, will have in the pentagon linkage mechanism insertion tube of tooth piece, sealing cover will be pressed on the mouth of pipe,, make coupling shaft (0 by handle swivel nut sleeve
1) reach, because of connecting sleeve (5) withstands on the sealing cover and can not move forward, so between the bidentate piece apart from coupling shaft (0
1) reach and increase, be gripped in inner tube wall and no longer include mobile until the bidentate piece, continue swivel nut sleeve (9), seal ring (11) and seal ring (8) are pressed on ut socket and sealing cover respectively and reach between the sealing cover and the mouth of pipe, the pipeline opening of the provisional sealing of desire is sealed fully.Finishing using only needs nut is unscrewed.Under the effect of spring, two tooth piece natures are drawn close to the centre, and sealer can take off easily.
But this sealer is the quick-sealing mouth of pipe both, also can pull down very soon, and reusable.Its advantage is: itself has fastening ability utensil, needn't be again by welding, and use, convenient disassembly do not have damage to body, and can use repeatedly, and be time saving and energy saving, reduces material consumption, helps improving work efficiency.
This accompanying drawing is to use the assembling schematic representation, wherein: and 1,1 '-the tooth piece, 2,2 '-the back support arm, 3,3 '-preceding support arm, the 4-screw rod, the 5-connecting sleeve, 6-pressure spring, 7-sealing cover, 8-seal ring, the 9-ut socket, the 10-handle, the 11-seal ring, 12-is by the tube sealing road.
