Specific embodiment
The utility model includes two semicircular closure rings, and two semicircular closure ring structures are identical, is matched,
There is colloid-injecting gun 7 with what semicircle closure ring was used together, the sealant that leak stopping uses is perfused in colloid-injecting gun 7.
Semicircular closure ring is made of connecting plate 1, semicircular ring 2.
Fig. 1,2,3 show that connecting plate 1 is rectangle steel plate, and two pieces of connecting plates 1, which are respectively welded, is connected to the two of semicircular ring 2
End, the plate face of two pieces of connecting plates 1 is parallel with the line of centres at 2 both ends of semicircular ring, has respectively in the plate face of two pieces of connecting plates 1 vertical
In the fastening screw hole 4 of plate face.In use, two semicircular rings 2 are opposite, the connecting plate 1 at two 2 both ends of semicircular ring is opposite, fastening
Bolt passes through fastening screw hole 4 and two semicircular rings 2 is formed annulus, and annulus covers the circumference in flange.
Fig. 1,2,3 show there is the snap ring 3 of protrusion, circumference of the snap ring 3 along semicircular ring 2, snap ring 3 on the inner wall of semicircular ring 2
On the annular middle line of semicircular ring 2.The section of snap ring 3 be it is trapezoidal, trapezoidal bottom surface long side is located on the inner wall of semicircular ring 2,
Gap between trapezoidal top surface short side and two ring flanges 9 is opposite, less than two ring flanges 9 of length of trapezoidal top surface short side
Between gap width, the length of trapezoidal bottom surface long side is greater than the gap width between two ring flanges 9.The width of snap ring 3
Gap width between two ring flanges 9 is corresponding, and snap ring 3 can be inserted into the gap of two ring flanges 9, proper with clearance fit
To benefit, can either be inserted into, can not two sides have gap leak adhesive, therefore the design of snap ring 3 is whether plug leak position succeeds
An important factor for.
Fig. 1,2,3,4 show there is hole for injecting glue 5 in semicircular ring 2, the import of hole for injecting glue 5 is on the outer wall of semicircular ring 2, injecting glue
The outlet in hole 5 is on 3 top surface of snap ring of semicircular ring 2, the import connection glue injection connector 6 of hole for injecting glue 5, injecting glue connector 6 and colloid-injecting gun 7
It is connected.
Fig. 5,6,7,8 show, the utility model use process is as follows:
By two 2 sets of semicircular ring circumference in flange, the snap ring 3 on two 2 inner walls of semicircular ring is directed at two ring flanges 9
Gap is embedded into two snap rings 3 in the gap of two ring flanges 9；
The connecting plate 1 at two 2 both ends of semicircular ring is opposite, and fastening bolt passes through fastening screw hole 4 and fastens two semicircular rings 2,
Flange is clamped, the gap of two snap rings 3 and two ring flanges 9 is fitted close, without gap；
Colloid-injecting gun 7 is connected with injecting glue connector 6, sealant is heated to and slightly applied lubricating oil loading column glue rifle 7, then may be used
To start the sealant in colloid-injecting gun 7 from the gap for injecting two ring flanges 9 in hole for injecting glue 5；
The selection of first time decanting point is in the place farthest from leakage, by manual 7 connector of colloid-injecting gun at first time decanting point
Be screwed into injecting glue connector 6, by 7 continuous pressure of colloid-injecting gun, force sealant continuously pass through glue injection gun head and injecting glue connector 6 into
Enter in 9 gap of ring flange, when pressure gauge is at a time motionless, opens colloid-injecting gun relief valve, pressure is got off therewith；
Fastening bolt is unclamped, two semicircular rings 2 are rotated, so that hole for injecting glue 5 is directed at second of injecting glue point, tightens fastening spiral shell
Bolt fixes two semicircular rings 2 with flange, carries out second of injecting glue according to the sequence of first time；
Third time injecting glue is carried out according to the method described above, and during preceding injecting glue three times, the leakage point of ring flange 9 nearby has row
Leakage 16 out；
Semicircular ring 2 is rotated, keeps the 4th injecting glue point opposite with the leakage point of flange, carries out injecting glue after fastening semicircular ring 2, is infused
Glue rifle 7 is got to always until flange do not leak；
Leakage situation around flange is observed, as there is no new leakages in half an hour.
