Utility model content:
The utility model be intended to give one's hand suppress sealing and pinpoint inner liner stainless steel compound pipe molding suppress seal head.
The technical solution of the utility model is: inner liner stainless steel compound pipe molding suppresses seal head, comprise platform, platform is fixedly connected with feed cylinder, the feeding piston of feed cylinder is horizontally disposed with, packed-piston is provided with in the cannelure of feeding piston nose, seal is provided with between packed-piston and feeding piston, packed-piston has Step Shaft to be connected with the counterbore matched in clearance of spacing head, two sealing rings and a baffle ring is provided with successively in annular groove between the mating surface of packed-piston and spacing head, spring is provided with in space between the counterbore of spacing head and the end of packed-piston, be connected by sealing bolt between spacing head with feeding piston, spacing head and feeding piston centre have a center counterbore, center counterbore extend into feeding piston neck and is communicated with the pressurizing port of ft connection, pressurizing port connects suppresses high-voltage tube, bottom packed-piston with the piston chamber's outer wall between feeding piston have by-pass prot be connected high-voltage tube, feed cylinder connects high-voltage tube.
The end of the feeding piston coordinated with packed-piston outer cylinder surface is stainless steel locating ring, and stainless steel locating ring outer cylinder surface is threaded carbon steel locating ring.
The diameter of sealing ring is: the sealing ring overall diameter under nature be connected by the stainless steel tube inner diameter seal sealed, the sealing ring after plastic deformation with expand after stainless steel tube inner diameter seal be connected.
It is one group that two relative inner liner stainless steel compound pipe moldings suppress seal head.
The utility model has following beneficial effect: by arranging feeding piston and packed-piston, two are made relative suppress head and accurately can locate on carbon steel pipe and stainless steel tube length, packed-piston crush seal circle, sealing ring still can be sealed reliably after stainless steel tube expands, there is accurate location, seal reliable feature, favourablely to promote the use of.
Accompanying drawing illustrates:
Accompanying drawing 1 is Split type structure schematic diagram of the present utility model.
1-platform in figure, 2-feed cylinder, 3-feeding piston, 4-stainless steel locating ring, 5-packed-piston, 6-carbon steel locating ring, 7-spring, 8-center counterbore, the spacing head of 9-, 10-sealing ring, 11-baffle ring, 12-piston chamber, 13-pressurizing port.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, inner liner stainless steel compound pipe molding suppresses seal head, comprise platform 1, platform 1 is fixedly connected with feed cylinder 2, the feeding piston 3 of feed cylinder 2 is horizontally disposed with, packed-piston 5 is provided with in the cannelure of feeding piston 3 front end, seal is provided with between packed-piston 5 and feeding piston 3, packed-piston 5 has Step Shaft to be connected with the counterbore matched in clearance of spacing 9, two sealing rings 10 and a baffle ring 11 is provided with successively in annular groove between packed-piston 5 and the mating surface of spacing 9, spring 7 is provided with in space between the counterbore of spacing 9 and the end of packed-piston 5, be connected by sealing bolt between spacing 9 with feeding piston 3, a center counterbore 8 is had for spacing 9 with feeding piston 3 center, center counterbore 8 extend into feeding piston 3 neck and is communicated with the pressurizing port 13 of ft connection, pressurizing port 13 connects suppresses high-voltage tube, bottom packed-piston 5 with piston chamber 12 outer wall between feeding piston 3 have by-pass prot be connected high-voltage tube, feed cylinder 2 connects high-voltage tube.
The end of the feeding piston 3 coordinated with packed-piston 5 outer cylinder surface is stainless steel locating ring 4, and stainless steel locating ring 4 outer cylinder surface is threaded carbon steel locating ring 6.
The diameter of sealing ring 10 is: sealing ring 10 overall diameter under nature be connected by the stainless steel tube inner diameter seal sealed, the sealing ring 10 after plastic deformation with expand after stainless steel tube inner diameter seal be connected.
It is one group that two relative inner liner stainless steel compound pipe moldings suppress seal head.
During actual use, two be oppositely arranged suppress head under the effect of feed cylinder 2, feeding piston 3 does feed motion relatively, stainless steel tube is located by two stainless steel locating rings 4, carbon steel pipe is located by carbon steel locating ring 6, now spacing 9, sealing ring 10 and packed-piston 5 stretch into stainless steel inwall, pressurizing port 13 and packed-piston 5 are suppressed simultaneously, stainless steel tube expands under the effect of interior pressure, packed-piston 5 moves forward under pressure, rise outside crush seal circle 10 guarantee sealing effectiveness, be close in carbon steel pipe after stainless steel tube expansion plastic deformation and make finished product, pressurizing port 13 and packed-piston 5 pressure release, packed-piston 5 bounces back under the effect of spring 7, sealing ring 10 restores to the original state, feeding piston 3 bounces back, take out finished product multiple tube, according to the multiple tube of different size, change and different suppress head to adapt to the multiple tube of different size, the screw thread of adjustment carbon steel locating ring 6, can the position of accurate adjustment carbon steel pipe, ensure the linear contraction after stainless steel tube expansion.
