Description

A kind of three-way hose coupling
technical field:
The utility model relates to a kind of three-way hose coupling.
background technique:
Tee union is the one of pipe fitting joint, for connecting three different pipe fittings, can connect inside shunt by the fluid of tee union in threeway.Existing three-way hose coupling connects threadably, is threaded and needs to carry out pin and box sub a few rotation, easily cause hose twist, and outside screw thread is exposed to, easily hinder tooth, cause screw thread disorderly button, screw thread process time and technological requirement are all higher, add cost of production.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provides a kind of snap fit that adopts to connect, is connected firmly, good airproof performance, three-way hose coupling easy to connect.
In order to achieve the above object, the technical solution of the utility model is:
A kind of three-way hose coupling, comprise joint body, described joint body is provided with 3 connecting heads, described connecting head inside offers the first circular groove and the second circular groove, is provided with sealing plug, described sealing plug is provided with snap ring in described first circular groove; Described connecting head screws togather and is provided with set screw nut, described snap ring to be compressed with sealing plug by set screw nut and is connected.
Described snap ring inside offers the 3rd circular groove, the 4th circular groove and the first engagement portion, and described snap ring offers the breach of bar shaped.
The outer side surface of described snap ring is provided with retaining ring, described set screw nut is provided with fixing part, described snap ring is connected by retaining ring and fixing part clamping with set screw nut.
Offer annular protrusion in described first circular groove, described sealing plug offers the draw-in groove matched with described annular protrusion, described annular protrusion is connected with draw-in groove engaging.
Described sealing plug offers through hole, and the aperture of described through hole is identical with the internal diameter of the fluid passage of joint body inside.
The beneficial effects of the utility model are: a kind of three-way hose coupling of the present utility model, and set screw nut compresses snap ring, and snap ring is shunk, and snap ring carries out clamping to the pipe fitting of required connection; Offer annular protrusion in first circular groove, sealing plug offers the draw-in groove matched with annular protrusion, make sealing plug fixing more firm, better tightness.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
Embodiment 1
A kind of three-way hose coupling as shown in Figure 1, comprise joint body 1, described joint body 1 is provided with 3 connecting heads 2, described connecting head 2 inside offers the first circular groove 21 and the second circular groove 22, in described first circular groove 21, sealing plug 3 is installed, described sealing plug 3 is provided with snap ring 4.Snap ring 4 is for the clamping of pipe fitting, and sealing plug 3 plays buffering and improves the effect of sealing when pipe fitting connects.Described connecting head 2 screws togather and is provided with set screw nut 5, described snap ring 4 is compressed with sealing plug 3 by set screw nut 5 and is connected.
Described snap ring 4 inside offers the 3rd circular groove 41, the 4th circular groove 42 and the first engagement portion 43, and described snap ring 4 offers the breach 44 of bar shaped.Breach 44 can realize the clamping of pipe fitting and loosen making snap ring 4 under the extruding of set screw nut 5.The outer side surface of described snap ring 4 is provided with retaining ring 45, described set screw nut 5 is provided with fixing part 51, described snap ring 4 is connected by retaining ring 45 and fixing part 51 clamping with set screw nut 5.
Offer annular protrusion 31 in described first circular groove 21, described sealing plug 3 offers the draw-in groove 32 matched with described annular protrusion 31, described annular protrusion 31 is connected with draw-in groove 32 engaging, makes sealing plug 3 fixing more firm, increases sealing.Described sealing plug 3 offers through hole 6, and the aperture of described through hole 6 is identical with the internal diameter of the fluid passage 7 of joint body 1 inside, reduces resistance when making fluid enter fluid passage 7 by through hole 6.
A kind of three-way hose coupling of the present embodiment, set screw nut compresses snap ring, and snap ring is shunk, and snap ring carries out clamping to the pipe fitting of required connection; Offer annular protrusion in first circular groove, sealing plug offers the draw-in groove matched with annular protrusion, make sealing plug fixing more firm, better tightness.
