Embodiment:

Narrate embodiment of the present utility model with reference to the accompanying drawings, Fig. 1 and Fig. 2 are the structural representations of FERRULETYPE pipeline extension valve of the present utility model.As seen from the figure, FERRULETYPE pipeline extension valve of the present utility model comprises by double-screw bolt 9, double-screw bolt lid 10, screw rod 11, compression leg 12, compression leg lid 13, sealing gasket lid 14, ball 15, handwheel 17, and cap 18, sealing gasket 8, the spool that trim ring 16 and screw constitute and by a spool body I perpendicular to the pipeline body II of two coaxial lines and III and constitute the valve body 1 that its inner chamber of one is interconnected.Be characterized in adopting dividing equally separately band diagonal bar 26 to be arranged and have stretching of through hole and take 25 as the end cylindrical of the pipeline body II of two coaxial lines of the bolt fastening structure shown on Fig. 1 and III, circle all has interior round platform rank in two pipeline body ends, brake hoop 5 with parietal suture places place, round platform rank in this, packing ring 6 and seal ring 7 place the interior circle of pipeline body to contact with the brake hoop with parietal suture, its end is divided equally to have and is stretched bolt sleeve 3 the other ends of taking and stretch into that circle contacts with seal ring 7 in the pipeline body, and bolt 21 passes the pipeline body and stretches and take stretching of 25 through hole and corresponding bolt sleeve 3 with it and take through hole and be connected with nut 22; The pipeline body II of two coaxial lines of employing screw connection structure as shown in Figure 2 and the end cylindrical of III have outside thread 27 separately, interior circle all has interior round platform rank, brake hoop with parietal suture places place, round platform rank in this, two packing rings 6 that the centre accompanies seal ring 7 place the interior circle of pipeline body to contact the outside thread 27 of the external circle of nut sleeve 4 spinning in pipe deferents with brake hoop 5.

Wherein the interior circle of spool body I equates with the interior circle of the step of pipeline body II pipe tap.The pipe tap of pipeline body II matches with the sealing gasket of spool lid 14; The outside thread of double-screw bolt 9 lower ends cooperates with the interior round thread 24 of spool body I, the cylindrical of compression leg 12 and sealing gasket 8 cooperates with the interior circle of spool body I, the round platform rank cooperate in the upper end of trim ring 16 and sealing gasket 8 and spool body I, ball 15 places between screw rod 11 lower end surfaces and the compression leg 12 upper end central blind holes, the cylindrical of compression leg 12 cooperates with the interior circle of the spool body I of valve body, between compression leg 12 lower end steps and sealing gasket lid 14, sealing gasket 8 is arranged, and pass sealing gasket with screw 19 and cover 14 center holes and screw in the compression leg 12 end central blind holes, sealing gasket lid 14 is fused with compression leg 12.

During assembling, assemble valve core earlier: concrete linkage editor is earlier compression leg lid 13 to be inserted in screw rod 11 bottom stage places, again ball 15 is placed in the compression leg 12 end face blind hole center cone caves, pass compression leg lid 13 corresponding through holes with thread screw 20, screw in the compression leg 12 end face blind screwholes, screw rod 11 and compression leg lid 13 and compression leg 12 are fused; Second step, the big trim ring 16 at double-screw bolt 9 big step cylindrical places and sealing gasket 8 successively are inserted in the outer nose circle of double-screw bolt 9 big steps to be contacted with step greatly, again screw rod 11 is screwed in double-screw bolt 9, after central bore, the sealing gasket 8 and the little trim ring 16 of double-screw bolt 9 center hole end step inner circles successively are inserted in screw rod 11, be pressed into double-screw bolt 9, again double-screw bolt lid 10 be inserted in screw rod 11, and screw-in double-screw bolt 9 compresses sealing gasket 8; Again the sealing gasket 8 at cylindrical place, compression leg 12 middle part is inserted in put in place after, pass sealing gasket with hex screw 19 and cover 14 center holes and screw in the blind screwhole of center, compression leg 12 end, sealing gasket lid 14 is fused with compression leg 12, and sealing gasket 8 is pushed down in the part; The 3rd goes on foot the square spigot that handwheel 17 is inserted in screw rod 11, uses and cap 18 screw-in screw rods 11 heads, and screws handwheel 17; After the spool assembling finishes, again spool is screwed in the double-screw bolt valve body 1, until compressing sealing gasket 8.So far, whole FERRULETYPE pipeline extension valve assembling finishes.

During use, at first on the certain position of pipeline 23 end cylindricals of desire dress, tube wall groove according to operating mode processing certain specification, be taken up in order of priority again and be inserted in bolt sleeve 13 at two pipe end cylindricals, seal ring 7, packing ring 6, and brake hoop 5 is snapped in the tube wall groove of pipeline, then pipeline body one end of a coaxial line in the double-screw bolt valve body 1 of FERRULETYPE pipeline extension valve is stretched into circle in the end of a pipeline wherein earlier, close up bolt sleeve 3, seal ring 7, packing ring 6, pass the pipeline body with bolt 21 and stretch the through hole of taking on 25 through hole and the corresponding with it bolt sleeve 3, with nut 22 this root pipeline 23 and FERRULETYPE pipeline extension valve are fused again; In like manner, again the end cylindrical of another root pipeline 23 is stretched in the pipeline body of another coaxial line in the double-screw bolt valve body 1 in the circle, close up the bolt sleeve 3 that has been inserted in equally, seal ring 7, packing ring 6, the pipeline body that passes this coaxial line with bolt 21 is stretched and is taken 25 through hole and corresponding with it bolt sleeve 3 through holes, with nut 22 this root pipeline 23 is connected with FERRULETYPE pipeline extension valve and finishes using.

When adopting thread connecting mode, connect when using, its step is identical with bolt connecting mode, different is as long as nut sleeve 4 is screwed in the outside thread 27 of the pipeline body end cylindrical of two coaxial lines respectively, and screw two nut sleeve 4 respectively, can easily two pipelines be connected with FERRULETYPE pipeline extension valve and finish using.

When the pipeline incoming fluid, rotate the handwheel 17 of double-screw bolt valve body 1, by the advance and retreat of screw rod 11, drive the degree of tightness of compression leg 12, open or throttle down, just can open or close ducted fluid, and can control the flow of ducted fluid.
