Abstract
The utility model relates to a corrugated hose joint, which is composed of a corrugated hose, an inner screwed barrel, an outer sleeve barrel, a sealing fastener, a sealing wadding and a steel wire net cover. The corrugated hose is connected with the inner screwed barrel by screwing; a conical inner and an outer expansion rings impacts the sealing material and the steel wire net cover through the screwed connection with the outer sleeve barrel. The utility model changes the connection mode of directly connecting the corrugated hose with a flange in the prior art. When the corrugated hose occurs the local damage, the damaged part is removed, and the corrugated hose is installed again for using; the integral corrugated hose can not be discarded because of the local damage.
Description
The utility model relates to a kind of technical field of corrugated body hose coupling.
In the prior art, the corrugated body flexible pipe is to stretch and be rolled into the helical tube wall with Stainless Steel Tube to make, its tube wall is thinner, about 0.5mm, than the light 3-5 of the rubber pipe under the equal operating conditions doubly, remarkable advantages such as being difficult for being converted into " dead angle " is arranged, be commonly used for the connection flexible pipe that needs flexible contraposition in the conveying of oil product or heat transfer medium, but the corrugated body Stainless Steel Flexible Hose after a period of time uses at the junction point of flexible pipe and hard tube, occur easily breaking, cause dielectric leakage, and remaining part is intact, this is owing to pressing place at flexible pipe and flange, flexible relatively poor, because the flexible pipe tube wall is thin, during operation, the sphere of activities is big, flexible pipe near pressing place is subjected to maximum stress and strain often, is subjected to the effect of the alternating stress and the pulsation temperature difference for a long time, in root generation fatigue fracture, and because of tube wall approaches, fracture is long and narrow, spiral groove depth and narrow, reasons such as flexible pipe outer cover Stainless Steel Cloth, can't repair welding, so that whole steam oil filling riser scrapped.
The purpose of this utility model is to design a kind ofly when the flexible pipe local damage, can remove broken parts at the scene very soon, makes all the other intact parts ressemble the corrugated body stainless steel soft pipe joint of use.
The utility model is achieved in that whole joint is by the corrugated body flexible pipe, the internal thread tube, outer sleeve, sealing fastener, stuffing box packing, the steel wire guard is formed, internal thread tube (2) small end screw thread and stainless steel ripple hose body (8) screw, internal spiral line tube (2) holds screw thread to be connected with outer sleeve (3) internal thread greatly, for sealing fastener applies pretightening force, sealing fastener is made of the cone match of interior packing (4) and outer packing (5), holds sealing soft packing (6) and steel wire guard (7) respectively tightly, sealing and fixedly steel wire guard (7) and corrugated body flexible pipe (8).
The utility model has the advantages that: at 10kg/cm
2Pressure under because the effect of sealing fastener, its favorable sealing property, do not have and leak, only need general purpose tool during installation, simple to operate, when local damage appears in hose coupling, be convenient to pull down joint removal broken parts and install again and can put into operation, can reduce the loss in a large number.
Accompanying drawing is a section erection drawing of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
The utility model is by corrugated body flexible pipe internal thread tube, outer sleeve, sealing fastener, sealing soft packing, and the steel wire guard is formed, the small end of internal thread tube (2) has screw thread, screw with the helical tube wall of corrugated body flexible pipe (8), make the preliminary fix in position of flexible pipe, the big end of internal thread tube (2) also has screw thread, be connected with the internal thread of outer sleeve (3), for sealing fastener applies pretightening force, sealing fastener is that two covers cooperate in twos, and have a conical surface packing group of straight trough, the packing group is cooperated by the conical surface of dimension interior packing (4) of shape and outer packing (5) and constitutes, when outer sleeve (3) is connected with internal thread tube (2) when tightening, because the effect of packing group cone match makes pretightening force become the tight power of circumferential distribution, hold sealing soft packing (6) and steel wire guard (7) respectively tightly, play the fixedly effect of steel wire guard (7) and corrugated body flexible pipe (8), sealing soft packing (6) is made of the alternate winding with unsintered tape of asbestos rope, fill up the outer wall spiral chute and the end face of corrugated body flexible pipe, damage the tube wall of corrugated body flexible pipe (8) for fear of acute angle, the equal rounding of outlet end of internal thread tube (2) and outer sleeve (3), when the local damage of corrugated body flexible pipe, pull down body, remove broken parts, ressemble and can use, (1) is flanged joint of the present utility model.
Claims (3)
1. corrugated body hose coupling, by the corrugated body flexible pipe, the internal thread tube, outer sleeve, sealing fastener, sealing soft packing, the steel wire guard is formed, and it is characterized in that:
The small end of a. described internal thread tube (2) has screw thread, screws with corrugated body flexible pipe (8) to be connected;
The big end of b. described internal thread tube (2) has screw thread, screws with the internal thread of outer sleeve (3) to be connected;
C. described sealing fastener is made of interior packing (4) and outer packing (5);
D. described sealing soft packing (6) is made of the alternate winding with unsintered tape of asbestos rope.
2. a kind of corrugated body hose coupling according to claim 1 is characterized in that, the interior packing (4) and the outer packing (5) of described sealing fastener are cone structures.
3. a kind of corrugated body hose coupling according to claim 1 is characterized in that, the outlet end of described internal thread tube (2) and outer sleeve (3) all has the angle, garden.
