Abstract

A seal and flexible connecting method of a metal pipe consists of a metal pipe connected, a flexible connector body, a pressure nut, an enclasped open ring, a seal open ring, a hard seal ring, and a soft seal ring. A traditional thread connecting method for metal pipes is replaced by a new method that an internal cylindrical chamber and a trumpet-shaped opening of the chamber are filled with a plurality of seal rings and a plurality of open rings, which cooperate with each other and are fit into the connected metal pipes externally, openings of the connected metal pipes are expanded into a trumpet shape, the pressure nut pushes and presses parts outside the connected pipes to bring them into corresponding play, so as to reach the purpose of firm locking and leakage prevention.

Description

A kind of metal pipe sealing movable connection method

The present invention relates to the technical field of metal pipe sealing linkage structure.The be tightly connected technical field of structure of particularly a kind of thin-walled stainless steel tube.

Traditional metal pipe sealing moveable connection method, main be threaded, flange connects, thin-wall copper pipe is with overlaying the formula connection, these conventional methods are difficult to realize the seal for pipe joints flexible connection of hard.

The objective of the invention is to overcome the prior art deficiency, a kind of metal pipe sealing movable connection method that loading and unloading are quick, simple between pipe section, sealing is firm is provided.

The present invention is achieved through the following technical solutions, metal pipe sealing movable connection method: include being connected metallic conduit, movable joint body, gland nut, holding trip ring tightly of bell mouth shape, seal split ring, hard seal ring, soft seal ring and form.Specialization is that the metal tube road junction is expanded into than the big bell mouth shape of its original metallic conduit bore with special tool, and its pipeline place of being connected puts gland nut respectively, holds trip ring tightly, seal split ring, hard seal ring, soft seal ring.Soft seal ring can be folded mutually with two and use.Insert afterwards in the movable joint body cavity, with gland nut and the corresponding fittings body outside thread effect that cooperates, compress and push above each parts, and make and hold trip ring tightly and hold connected metallic conduit tightly, reach and seal firm purpose, play the effect of sealed rigid.

Below in conjunction with drawings and Examples structure of the present invention and advantage are further described.

Fig. 1 is a section assembly structure figure of the present invention.

Referring to Fig. 1, the thin wall metal pipeline sealing movable connection method of present embodiment, mainly by connected pipe 8, movable joint body 1, gland nut 2, hold trip ring 3, seal split ring 4, hard seal ring 5, soft seal ring 6, metallic conduit 8, horn mouth 7 tightly and form.Respectively for the toroidal of a breach is arranged, seal ring 5,6 respectively is unnotched circle shape to trip ring 3,4.Metallic conduit 8 is a thin-wall stainless steel, and soft seal ring 6 usefulness rubber materials cause, and movable joint body 1, gland nut 2, holds trip ring 3 usefulness brass materials tightly and causes, and seal split ring 4, hard seal ring 5 usefulness stainless steel materials cause.When connecting thin-walled stainless steel tube 8 operations, put gland nut 2 respectively successively at its pipeline junction, hold trip ring 3 tightly, seal split ring 4, hard seal ring 5, soft seal ring 6, the special-purpose belling tool in back, its Stainless Steel Tube road junction is expanded into bell mouth shape 7, holding trip ring 3 tightly arranges with each opening mutual dislocation of seal split ring 4, and with the hard seal ring, soft seal ring is put into the inner chamber of movable joint body 1, the outside thread 9 of gland nut 2 movable joint bodies 1 with matching is joined, firmly rotate gland nut 2, each parts in movable joint body 1 chamber are compeled in pushing, make each parts play corresponding useful effect, and push soft seal ring 6 and be out of shape expansion, stop up movable joint body 1 inner chamber, prevent that effectively object is held trip ring tightly and held thin-walled stainless steel tube 8 tightly to external leakage in the connected thin-walled stainless steel tube 8.Reach and block firmly and the purpose of leakproof.

Such structure, the present invention compares with conventional art, has obvious advantage.

1, adopt the active joint method of attachment of the thin wall metal pipeline of outside ring closing bell mouth shape, operation is convenient, Loading and unloading are simple, quick.

2, adopt specific purpose tool that the oral area of thin-walled stainless steel tube is expanded into the bell mouth shape form, padlock is tight easily Close, make it to be difficult in the joint body cavity, to deviate from.

3, adopt the configuration mode hold trip ring compressing seal split ring, hard seal ring, soft seal ring tightly, reach tube sealing effectively firmly and the effect of leakproof.

Claims (4)

1. metal pipe sealing movable connection method comprises bell mouth shape metallic conduit, movable joint body, gland nut, holds trip ring, seal split ring, hard seal ring and soft seal ring tightly and form.It is characterized in that: device goes into to cause being connected of bell mouth shape to be set with soft seal ring, hard seal ring, seal split ring on metallic conduit and its pipeline and to hold trip ring tightly in the movable joint body cavity.The collar extension mutual dislocation of each trip ring is arranged during connection.With being enclosed within the gland nut and the corresponding movable joint extracorporeal thread that matches that is connected on the metallic conduit, under external force, trip ring, seal split ring, hard seal ring and soft seal ring are held in pushing tightly, make it to block and press metallic conduit.
2. metal pipe sealing movable connection method according to claim 1 is characterized in that the described trip ring of holding tightly causes the inner tooth thread shape, and respectively for the toroidal of a breach is arranged, described seal ring respectively is unnotched circle shape to described trip ring.
