Abstract

The invention relates to a universal fluid T joint capable of being rapidly assembled and disassembled for a rotating shaft. The universal fluid T joint comprises a T joint body, wherein the T joint body is provided with two horizontal connecting ends and a perpendicular connecting end; outer hexagonal lap joint nuts (I and II) are sequentially arranged outside the two horizontal connecting ends respectively; a lap joint blocking core is embedded into the joint of the outer hexagonal lap joint nut I and the inner tube wall of the T joint body; a gasket is arranged between the outer surface of the lap joint blocking core and an internal thread of the outer hexagonal lap joint nut I. the universal fluid T joint has the beneficial effects that production cost is reduced, mounting space and site construction time are saved, and attractive appearance is achieved; the universal fluid T joint can be freely regulated within 360 degrees, and is high in practicability; a plastic sealing mode is adopted, so that the universal fluid T joint is high in sealing performance; interfaces at different positions are unfixed, so that the universal fluid T joint is adapted to a more flexible mounting environment; for industry system transformation or function promotion projects, no previous pipeline system is involved, and by rapid interface construction, construction time is reduced, and the risk of sealing performance damage or component damage after the original system is involved is eliminated.

Description

A kind of universal rotating shaft fluid tee union of fast demountable

Technical field

The present invention relates to a kind of fluid tee union, particularly relate to a kind of universal rotating shaft fluid tee union of fast demountable.

Background technique

Tee union is the one of pipe fitting, and its Connecting format is exactly direct by threeway and steel pipe butt welding, divides generally have equal tee, reducing tee etc. according to pipe fitting bore; Divide according to arm direction and have positive threeway and skew T; Threeways such as having carbon steel, alloyed steel, stainless steel, copper, pvc is divided according to material; Divide according to Placement and have common threeway, screw thread threeway, cutting sleeve triplet, spigot and socket tee; Top system, compacting, forging, casting etc. is divided with making method.

Tee union shaping is the pipe by being greater than threeway diameter, flattens about to the size of threeway diameter, opens a hole at the position of stretching arm; Pipe, through heating, is put into forming die, and in pipe, is loaded the punch die of stretching arm; Pipe is radially compressed under the effect of the pressure, and in the process of radial compression, metal flows to arm direction and form arm under the stretching of punch die; Whole process is shaped by the radial compression of pipe and the drawing process at arm position.After adopting heating, suppress threeway, the equipment tonnage required for material forming reduces, and the adaptability of hot-pressed three-way pipe fitting to material is wider, is applicable to low carbon steel, alloyed steel, stainless material; The threeway that particularly major diameter and tube wall are partially thick, adopts this formation technique usually.

This case it is important to note that, tradition threeway is by after screwed tight, its screw socket physical location is in fixed position relative, therefore the position and the direction that connect load are also relatively-stationary, load can only be increased according to the position of screw socket, position corresponding to installation load can not be come according to self-demand, inconvenient and practicability is low; Simultaneously, when tradition threeway increases load, each interface must increase outside thread or internal thread could be connected with load, or externally connected pipe bore is less, when needing less bore could connect load, an outside thread reducing internal thread must be increased just can use, therefore traditional threeway must increase by three external connection screws in use and could be connected with load, increases cost of production and operation inconvenience, how easy connecting link is leaks; Further, traditional threeway sealing is all sealed by raw meal belt, and sealing effect is poor, need to regularly replace.

Therefore, for above aspect, need effectively to innovate prior art.

Summary of the invention

For above defect, the invention provides a kind ofly to save time, simple to operate, exterior appearance, cost are lower, the universal rotating shaft fluid tee union of sealing preferably fast demountable, to solve many deficiencies of prior art.

For achieving the above object, the present invention is by the following technical solutions:

A kind of universal rotating shaft fluid tee union of fast demountable, comprise threeway body, described threeway body has two level connection joint end connecting ends vertical with, two level connection joint end outsides wherein arrange outer-hexagonal kink nut I, outer-hexagonal kink nut II successively respectively, vertical connecting end outer installment kink nut wherein;

Described outer-hexagonal kink nut I embeds a kink with threeway body inner tubal wall joint and keeps off core, and between kink gear core outer surface and the internal thread of outer-hexagonal kink nut I, arrange pad, this pad is made of plastics;

The level connection joint end outer surface connected with outer-hexagonal kink nut I with outside thread, with in the threeway body tube cinclides of vertical connecting end connecting part with internal thread.

Each kink nut interior is all threaded, and the kink nut interior of described vertical connecting end outer installment is with outer-hexagonal kink internal thread.

The beneficial effect of the universal rotating shaft fluid tee union of fast demountable of the present invention is:

(1) by directly arranging outside thread, internal thread, reducing internal thread in threeway, load can be directly connected with threeway, and do not need external outside thread, internal thread, outside thread reducing internal thread, and only directly twisted by load when installing and admittedly can realize using effect at once, save and make material, reduce cost of production, save installing space and on-site construction time, attractive in appearance;

(2) by arranging outer-hexagonal kink nut, screw socket can be adjusted arbitrarily in 360 ° of directions, increase load time can carry out arbitrarily angled connection according to oneself requirement, avoid produce because of loading interfaces position not on and affect load connect, practical, more humane, easy to operate;

(3) reach sealing effect by the structure of plastic spacer and global design, the sealing of relative raw meal belt improves the reliability of sealing, simple to operate, do not need professional person to operate, reduce human cost, good airproof performance, attractive in appearance;

(4) diverse location Active Interface, can connect outside thread, internal thread, outside thread that bore is less respectively, adapts to installation environment more flexibly;

(5) for Industry system transformation or functional promotion project, the pipe-line system before can not needing to relate to, is constructed by fast interface, greatly reduces the engineering time, gets rid of and relate to sealing after original system and destroy or the risk of component damage.
