Abstract
A pipe fitting joint includes an adapter sleeve, a seal ring and a pad disposed in the adapter sleeve and a cutting sleeve connected with the adapter sleeve. The pad is set outside the seal ring and the end of the adapter sleeve has bellmouths. In the cutting sleeve there is an elastic block, whose end surface is connected with the pad. On the inner wall of the elastic block is connected a jack catch.
Description
Technical field
The present invention relates to a kind of pipe connecting device, relate in particular to a kind of pipe fitting joint.
Background technique
Its two ends of existing pipe fitting joint all car are shaped on internal thread, and the end that is attached thereto the pipe fitting that connects also car is shaped on outside thread, and both direct screw threads join, and seal with stuffing such as greasy filth, fibers in the threaded connection place, install, the dismounting difficulty, and labor intensity is big.And this pipe fitting joint produces corrosion easily in the threaded connection place, very inconvenience when dismounting or maintenance, the time regular meeting sliding dental phenomenon takes place.
Chinese patent CN03205588.9 provides a kind of pipe joint, it mainly is made up of fittings body, collar, stuffing box gland, claw, tapered sleeve and opening sleeve, it is characterized in that: stuffing box gland surrounds the outer ring of pipe fitting, be provided with bulge loop in the stuffing box gland, opening sleeve is enclosed within on the stuffing box gland, slide relative places fittings body but opening sleeve external diameter two nose cones circle and tapered sleeve inner cone circle fit, claw inner end and tapered sleeve join, but the claw male cone (strobilus masculinus) pastes slide relative mutually with the fittings body inner conical surface, and the end face that collar is screwed into fittings body port inner end and claw joins.This pipe joint has good sealing, has also solved installation, the difficult problem of dismounting to a certain extent, still, and its structure more complicated.
Summary of the invention
The pipe fitting joint that the purpose of this invention is to provide a kind of simple in structure, easy to loading and unloading, good airproof performance.
For achieving the above object, the present invention is by the following technical solutions:
Pipe fitting joint of the present invention, comprising swagelok and the seal ring that is arranged in the swagelok, the swagelok end has an internal diameter expansion area, the outside of this expansion area is outward-dipping conical surface, the inboard is a circular step, seal ring is arranged on this step, and pad and seal ring are arranged side by side; This pipe fitting joint also comprises the cutting ferrule that is connected with the swagelok plug-in mounting; The end of cutting ferrule evenly is provided with a plurality of elasticity cards along circumference, the rear end outer side surface of this elasticity card and the internal surface of swagelok are fitted, the outer surface of the front end of elasticity card has boss, and this boss is resisted against on the conical surface of swagelok expansion area, and elasticity card top is resisted against on the pad.
Be fixedly connected with the stainless steel claw on the inwall of above-mentioned elasticity card, the corpus unguis of this claw partly is embedded in the elasticity card, and the top of claw is passed and in the inwall projection of elasticity card.
Have the tooth of choking on the inwall of above-mentioned elasticity card.
The present invention will treat that by elasticity card and claw jointed tubular workpieces blocks, install, dismounting is very convenient, and need not joint and treat the end thread cutting of jointed tubular workpieces and present PVC and PP-R body gluing, add hot connecting.Reduced staff's labor intensity, also avoided the corrosion phenomena of traditional pipe fitting joint fully in the threaded connection place; The cylindrical of seal ring and the internal chamber wall of swagelok join, and interior circle tightly is enclosed within on the outer wall of pipe fitting, play good seal action.

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
A kind of pipe fitting joint, as shown in Figure 1, comprising swagelok 1, the cutting ferrule 5 that is arranged on seal ring 2 and the pad 3 in the swagelok 1 and is connected with swagelok 1 plug-in mounting; Swagelok 1 end has an internal diameter expansion area 11, the outside of this expansion area 11 is outward-dipping conical surface 12, the inboard is a circular step 13, seal ring 2 is arranged on this step, pad 3 is arranged side by side with seal ring 2, and seal ring 2 and pad 3 can endwisely slip at the internal chamber wall of swagelok 1, and the distance of its slip is 2mm-2.5mm; Cutting ferrule 5, its structure such as Fig. 1, shown in Figure 3, its end evenly is provided with 3-8 elasticity card 4 along circumference, the rear end outer side surface of this elasticity card 4 and the internal surface of swagelok 1 are fitted, the outer surface of the front end of elasticity card 4 has boss 41, this boss 41 is resisted against on the conical surface of swagelok 1 expansion area, and elasticity card 4 tops are resisted against on the pad 3.
In addition, can also be fixedly connected with stainless steel claw 6 on the inwall of elasticity card 4, the tooth of choking perhaps directly is set on the inwall of elasticity card 4.
In the present embodiment, seal ring 2 its employing food grade silica gel material are made good springiness and nontoxic pollution-free; The structure of claw 6 such as Fig. 4, shown in Figure 5, its top has the outer flange of arc, and the bottom has arc groove, and it adopts stainless steel material to make, method by injection moulding is embedded in it in elasticity card 4, only stays the outer flange on top to pass and be raised in the inwall of elasticity card 4.During installation, the internal chamber wall of the cylindrical of seal ring 2 and swagelok 1 joins, and interior circle tightly is enclosed within on the outer wall for the treatment of jointed tubular workpieces, plays good seal action; Elasticity card 4 and claw 6 are inserted in the swagelok 1 for one, wait to take over to plug to get final product, and it is very convenient to install, dismantle.
In the foregoing description, whole pipe fitting joint sleeve pipe is PVC or the molding and forming of PP-P material except that claw 6 and seal ring 2 entirely.
Use the present invention with pipe fitting connect finish after, when in the pipe during pressurized, seal ring 2 and pad 3 pressurizeds move to cutting ferrule 5 directions, pad 3 promotes cutting ferrules 5 and moves, when cutting ferrule 5 moved, elasticity card 4 was pushed by conical surface 12 and shrinks.Like this, elasticity card 4 and claw 6 get the pipe fitting card more firm.And the pressurized in the pipe is big more, and elasticity card 4 shrinks tightly more, and elasticity card 4 and claw 6 must be tight more with the pipe fitting card, and be firm more.
Pipe fitting joint of the present invention can be made forms such as becoming tee union, cross fitting, straight formula joint, curved formula joint to adapt to various needs.The present invention can be applicable to the connection of running water pipe, liquefaction liquid such as tracheae or gas delivery pipe fitting.
