Be a gate valve 251 through hole 241 part that formed by tube sections 221, its effect be by Hole 241 is divided into upper chamber and lower chamber, i.e. every intermediate pressure section 241a and 241b.Tube sections 221 Forming the wheel hub of drum assembly parts 253, the function of drum assembly parts is the gate valve 251 covering and being in open mode, As shown in Figure 5.Drum assembly parts 253 are made up of upper head plate 255 and bottom plate 257.Bottom plate 257 has One tabular, the bottom 259 that radial direction extends, an outer circumference wall 261, and an interior annular Wall 263.Upper head plate 255 has a tabular top 263 (similar with bottom 259), an outer circumference Wall 265 and an interior annular wall 267.Upper head plate 255 and bottom plate 257 are fixed together is a set of Threaded bolt 269.Bottom 259, top 263 and wall 265 and 267 determine an annular compartment 271, it is adaptable to accommodating gate valve 251 and rest in a narrow annular channel 273, slit is by annular wall 263 He 265 apart from one another by face formed.Pressure seal between gate valve 251 and slit 273 is placed on by a pair O-ring 275 and 277 in annular inner wall 263 provides.They ensure that when the feelings of closed shutter valve 251 Under condition, perforated, upper end 241a can separate with perforated, lower end 241b.Another o-ring 278, drum assembling assembly 253 when being used for providing gate valve 251 to open between outside circumferential wall 261 and 265 Interior gas pressure is maintained at below certain value.

From the annular solid 252 of gate valve 251 extend out for anchor shank 250, for changeover valve (accompanying drawing 5). Anchor shank is stapled on threaded screw 275, and screw is rotatably mounted on a bull-nose, this projection Thing extends at upper chamber plate 255.Screw 275 is fixed by nut 279.O-ring 281 carries Supply the sealing between bull-nose 277 and bolt 275.The hexagonal end 283 of bolt 275 uses Spanner can make valve 251 change between the open and closed positions.

In order to the pressure in monitoring hole 241, in tube sections 223, (accompanying drawing 4) installs one Screwed hole 283, installs a pressure vessel 285 in screwed hole.The upper chamber district 241a of hole 241 The pressure discharge formed is completed by the opening 287 in same tube sections 223, and opening is with threaded Cylindrical part 289 weld together, form a floss hole, on floss hole install a ball valve 291 (hereinafter referred to as " secondary ball valve "), can select the ball valve of traditional structure.One similar ball valve 293 (this It is referred to as " cue ball valve " afterwards), for providing the bypass path through accompanying drawing 1 inner catheter 107, bypass path It is arranged on a cylindrical part 295 (accompanying drawing 5) and is welded on tube sections 219, passing through tubulose Opening on thing part 219 wall and lower end cavity area 241b communication, wall upper shed is similar with opening 287, But it is shown without.

Top in view of fixture 200 is an outlet, for making the appropriate section of annex 300-900 divide Open.Formed intake section be tool container 297, including one thereon end have ring edge 299 and Its shoulder 301 is gradually converted into size and reduces, the bracket of external screw thread terminal part 303.Tool container is on limit It is internal thread in edge 299, and receives different annexes 300 in being partially into the main body of terminal part 303 -900.Owing to these annexes are fabricated from iron, preferred tool container 297 also has iron to make.System is held Device 297 is tied by clasp 305 with tube sections 223 in porch, and clasp can be aluminum products, Can also be that all parts forming tube 237 are tied.Clasp 305 have one reduced size of Upper part 307 and an end portion 309 amplified.Clasp 307 is with outside with tool container 297 The screw thread that screw thread matches, and the clasp part 309 amplified also includes that one is enclosed within tube sections 223 Upper external screw thread match engagement internal thread.O-ring 313 and 315 is at clasp 305 and inserts clasp 297 And between tube sections 223, the pressure each providing tube sections 223 and container 297 seals.

By pipe laying 100 that fixture 200 and bottom tube unit 217 are put together and lowerd On fixture, tube sections 217 knocks down tube sections towards seatpillar the end of a thread 113, such pipeline The entrance 242 of 217 is until the bottom of wide shape thing part and saddle portion 111 connect.Pipeline head 113 is close It is assembled together with the hole of tube sections 217 and passes through o-ring 243 and 245 and keep sealing by both. A pair L-type upper end support element 317 is welded together to form one with tube sections 217 and is connected support Top, the bottom of this support includes a bracket 319 with center reinforcement thicker region 321.Bracket 319 Sizing, therefore when pipeline is orbicular time, its inner surface mates with the size and dimension of pipeline.

Welding stretch out from any side, bracket 319 both sides is a pair lower bracket element 323.Iron stretch Enter 325 and stretch in hole (not shown) through the pedestal of L-bracket 317, and iron stretch into 327 Stretch into (not shown) in the hole of lower bracket part 323 terminal.Iron hole 329 has threaded Shank 331 and handle 333, extend through upper bearing (metal) bracket 317 and lower bearing bracket 323, and spiral Mesh together with the respective iron head that stretches into.Upper bearing (metal) bracket 317 and lower bearing bracket 323 and both Relevant parts include the device consistent with tube 237, and for by fixture 200, particularly tube is even Receive on pipeline 100.

By rotating handles 333, upper bearing (metal) bracket and lower bearing bracket, the other side the most in opposite directions moves, and causes bottom to be managed What shape thing part 317 was firm is fixed on pedestal, relative with the saddle portion 111 of branch road saddle 109.Spirit Position, by pressing pipeline 100 to support 319, it is assumed that pipeline is circular, relative with slightly oval shape, I.e. another conventional hypothesis of pipe shape.Drive upper bearing (metal) bracket 317 and the mutual phase shift of lower bearing bracket 323 Dynamic further result is that the center line of pipeline 100 is relative to the center line at a right angle 90 of the entrance 242 of fixture Degree, therefore also becomes 90 degree relative to the center line of branch road seatpillar trace header 113.As a result, when outer dia and pipe The instrument that the internal diameter of trace header 113 mates very much through pipeline head enter in pipeline time, instrument is guided by pipeline head Therefore the center line of instrument also becomes 90 degree with the center line of pipeline 100, due to center line and the pipeline 100 of pipeline head 113 Center line intersect, the center line of instrument also can intersect.

Referring now to accompanying drawing 6-9, the first plug-in package can be described here, for through fixture 200 Pipeline.Cutting plug-in package 400 and critical piece thereof include axle 401, sealing-plug 40, cutter 405 with And a guiding wheel hub 407.Axle 401 has a handle 409 and enters threaded tube head 411 by screw Interior open at one end and the terminal of opposite side.Instrument 405 supports (accompanying drawing 7) by threaded tube head 411. Guiding wheel hub 407 to include an external screw thread body 413 and a turret head 415, pin 417 is through turret head Hole in 415 extends into the respective aperture in axle 401.Axial bore 419 is more bigger than the diameter of axle 401, prolongs Stretch and pass guiding wheel hub 407, it is allowed to its on axle 401 around pin 417 slight oscillatory, meeting after reason Explain.Time through hole 421 above the sealing-plug 403 being placed exactly in axle 401, therefrom passes and extends Time removable spring clip 423.

Sealing-plug 403 includes a slot member 425 with turret head 428, wherein extends an outer spiral shell Rotation column part 427, terminal is positioned at the less the most threaded part 429 of size, part 429 with One outside sealing o-ring 431.Shading ring 433 there is internal thread thus with the screw thread of column part 427 Matching, this part top of precession is until connecting with the lower surface 435 of turret head 428.

By the extension of the most threaded terminal part 429 is axial hole 437, and design size can be with axle 401 External diameter closely cooperate.From its upper end enter sealing-plug 403 and to hole 437 extend be reaming 439, tool Have when spring clip 423 is after axle 401 removes, be suitable to accommodate the screw thread 441 of the screw thread 413 guiding wheel hub 407.

Can be best in accompanying drawing 8 see, cutting tool 405 includes two parts: cutting wheel hub 451 He Shell cutter 453.Wheel hub 451 is typically cylinder, extends along radial direction, annular flange 455 ring Around the middle part of wheel hub, hub body has hexagonal cross-sectional 457 (in accompanying drawing 8 it can be seen that) above flange And an external screw thread column part 459 extends below flange.Threaded hole 461 axially extends And through wheel hub 451.

Referring now to a lower casing cutter 453, including an iron cylinder 463, there are incision two ends The slit 465 of wherein one end, slit extends along the direction angled with the center line of cylinder 463, Each slit terminates in an annular cutout 467.Slit 465 defines multiple has end face 471 Tooth 469, the relatively plate with the median perpendicular of cylinder 463 are inclinations.

Accompanying drawing 9 can preferably be seen, one group of backbone 471 in the inner loop of shell cutter tooth 469 around prolonging Stretch, just do not reach most advanced and sophisticated 473.

The upper end of shell cutter 453 terminates in internal thread edge 475, and screw thread therein is suitable to and cutter The screw thread 459 of wheel hub 451 with the use of.

In order to be combined by cutter 405, cutter hub 451 screws on spindle nose 411 until flange The bottom of 455 enters on axle, as shown in Figure 8.Then, shell cutter 453 is screwed into the spiral shell of wheel hub 451 Line part 459.So that cutter can be fixed closely, use a pair diametrically opposed hole 471, hole is positioned at cylindrical wall, so can stretch into pin and pass through thus overturn by cutter 453 On wheel hub 451.

The operation of plug-in package 400, especially on it, the operation of cutter 405 is upgraded by by assembly 400 Start, thus can be above fixture 200 and careful assembly 400 be inserted, wherein cut Cutter 405 is directed across fixture container 297.Be then threaded into sealing-plug 403 make it into container 297 until The end face 300 of container 297 is arrived bottom shading ring 433.Spring clip 423 is positioned at the top of axle 401, such as figure Shown in 7, whole plug-in package 400 will be placed on the top of gate valve 251, because spring clip 423 and container The face 300 of 297 connects.Then gate valve 251 is opened.Spring clip 423 one is walked at axle 401, and will It is internal that axle is pressed into fixture 200, and the direction towards pipeline is pressed into until guiding the screw thread on hub body 413 Mesh together with reaming 439 internal thread on sealing-plug 403.Then swing handle, drives and guides wheel hub 407 enter sealing-plug 403, at the original position mark number of cutting operation.Preferably, the chi of cutter 405 Very little can being close to assembles through branch road seatpillar trace header 113, so can go out in the wall internal cutting of pipeline 100 Mating holes.The operation of loweing of cutter 405 through branch road seatpillar trace header 13 becomes easier to, because axle 401 Can exist guiding in wheel hub 407 spacing between slight movement and endoporus 419 and axle.

Along with the rotation of handle 409, guide wheel hub 407 to be pushed into sealing-plug 403, axle 401 all rotate and to The direction reach of pipeline 100, causes the tooth of cutter 469 be engaged with the wall of pipeline and start to cut through pipeline Wall.It should be noted that the position guiding wheel hub 407 is relative with cutter crown end 473 on axle 401, when When guiding the screw thread on wheel hub 407 and sealing-plug 403 to engage first, crown end 47 is from each other on pipeline Interval, side a small distance.The bottom surface 475 that cutting operation is continued until on the turret head 415 guiding wheel hub with The end face 477 of the turret head 428 of sealing-plug is connected.The tip 473 of bottom surface 475 and cutting teeth 469 it Between distance as shown in the region A in Fig. 7, this region is selected so that face to face 475 and 477 when connecting, Crown end 473 is located just at the midpoint of pipeline 100, thus avoids half section, the bottom surface of pipeline to there will be groove, This situation also can be advanced at cutter and occur during the midpoint of more piping.

The external diameter of shell cutter 453 should than the internal diameter of branch line seatpillar the end of a thread 113 and pipeline 100 slightly Little, such cutter 453 can by pipeline head 113 along with the drawing of 90 degree of directions of center line of pipeline 100 Lead, and cutter center line now intersects with the center line of pipeline 100.Just because of this, due to cutter Tooth is just at the midpoint of pipeline 100, then the wall of pipeline will be cut into an arcuate wall portion, generally It is referred to as " sample base ", arcuate member 79 as shown in Figure 8.Cutter 453 concrete due to the present invention Configuration, the internal edges of cutter tooth 469 is engaged mutually along the outer edge of 471 with sample base 479, so when complete After becoming cutting operation, can be extracted out by instrument by dextrorotation rotating shaft 401, sample base 479 cuts with shell Device 453 is extracted out together.It addition, the pipeline wood shavings produced in cutting process can enter directly through slit 465 The inside of cutter, then passes through cutout 467, and wherein cutout can be stayed in chamber, and chamber wall is cutting The bottom of device 453 and chamber is formed by Piping specimen base 479.Sample base and wood shavings by by cutter from Remove at its wheel hub 451 and dispose.

The result of abovementioned steps is, during the wall of pipeline 100 is pierced, within whole fixture Pressure, all can rise directly including the pressure in the annular space 271 in hole 241 and drum assembling assembly 253 Internal to being full of whole pipeline 100.The rotary shaft 402 lasting by use handle 409 is until guiding wheel hub 407 do not have Luo Wen to couple with between sealing-plug 403 completely, then the extraction of whole shell cutter 453 is also Just complete.On this point, pull up moving axis 401, until the top of cutter hub 451 and sealing-plug The bottom connection of 403.This meeting bullport 421 passes axle 401 and comes back to the top of sealing-plug 403, it is allowed to Spring clip 423 reinserts thus assembly is fixed to the top of gate valve 251 completely.It is then shut off lock The family of power and influence 251, and open secondary release valve 291 thus by the gas releasing in the 241a of upper hole space, So can reduce gas pressure therein.Once complete this step, will be by by sealing-plug 403 and solid Both containers 299 screwed apart of locking member 200 removes plug-in package 400 from fixture 200, then takes out Assembly 400.

Next step of process is to check the otch just made.Detecting lamp 500 shown in Figure 10 is for the purpose. It includes that a transparent Plexiglas's plug 501 is positioned at chamber 503, and chamber is screwed into a lamp sealing-plug In 505.Lamp sealing-plug 505 is for the function similar with the cutter sealing-plug 403 shown in Fig. 6, and outward Portion uses similar configuration.It is, it includes a tube 507, extend also at hex nut 509 And there is a relative thin and smooth terminal part 513, terminal part end has o-ring 515.Lamp seals Connector 505 has an axial hole 517, extends along the whole length direction of connector.The upper part in hole 517 It is threaded.

Turning now to Fig. 4, check the result of pipe cutting step, by sealing-plug 505 is selected into fixture The container 297 of 300 is internal installs detecting lamp 500.After this step completes, gate valve 251 remains and closes Close, because being secondary ball valve 291.Along with fixing of detecting lamp 500 safety, ball valve 251 can turn now To open position, bulb 531 is lit, and by window 501 visual observation pipeline 100.When carry out After observation, gate valve 251 cuts out, and secondary ball valve 291 is opened thus discharged from upper chamber part 241a Pressure, and by the screwed apart of lamp and remove.Secondary ball valve 291 is closed, and prepares for next step, Stopper is namely installed in pipeline 100.

Disclose two alternative embodiments.First is as illustrated in figs. 11-14, followed by description, Stopper plug-in package 600 include one with handles 603 axle 601, drive hub 605, sealing-plug 607 And stopper assembly 609.Axle 601, handle 603, sealing-plug 607 substantially to the corresponding portion of accompanying drawing 7 Part is similar to.Axle 601 is with clasp 611, and it is fixed on axle for being screwed into sealing-plug when drive hub 605 Time in 607, in axial direction move to axle.Owing to sealing-plug 607 is identical with during the sealing-plug 403 of accompanying drawing 7 , CONSTRUCTED SPECIFICATION as shown in the figure but will not be described.Should giving one's full attention to it, to have an inside narrow Seam, screws in screw thread and is used for accommodating the external screw thread 613 of drive hub 605, and in a reduced size of hole Termination, hole 437 as shown in Figure 7, axle 401 can be through this hole and slip into thus closely cooperate.Bullet Spring folder 615 is generally in the opening (not shown) of axle 601.

With reference to accompanying drawing 12, stopper assembly 609 includes the iron clasp 617 of a band mouth, and one hard Clasp 619 the most made of iron and flexure strip 621.Clasp 617 is cylindrical, with top axial opening 623 and lower end axially open 625.Upper end open 623 be threaded and accommodate axle 601 size reduce with One section of screw thread.The opening 629,631 and 633 of radial direction intersects with lower end axially open 625.

Cross section be U-shaped iron clasp 619 with a threaded entrance 635, be used for receiving band mouth and buckle The external screw thread size of ring 617 reduces end 637.Wall through iron clasp 619 extends an inflow/outflow Opening 639, is also threaded for accommodating mould (not shown), and mould is for being formed around opening 639 The cartouche of flexure strip 621.Groove, spacing of about 1/8 inch, the inner surface at clasp 619 is formed Thus help to support flexure strip 621.

When flexure strip will be formed, screw (not shown) is screwed in opening 639.Screw has attached Arcuate surface (not shown) thereon, for drawing out arcuate surface 641 on flexure strip 621, this sheet cincture Inflow/outflow opening 639.Forming flexure strip 621 by inserting iron clasp 619 in a mold, bolt inserts In opening 639.In order to consistent with the present invention, the shape of mould is designed to when elastomer enters mould and iron During space between clasp 619 processed, the 643 of formation are thinner than sidewall sections 645.The most such Can become apparent from the when that reason being at that time with this instrument.After flexure strip is formed, perform to draw out action, thus when from Inflow/outflow opening 639 provides after removal tool (not shown) smooth arcuate profile 641.Should Notice through the chamber 645 being internally formed of the iron clasp of inflow/outflow opening 639 619 with through axially And along radial direction opening 625 and 631 have a paths.

It follows that the key step producing bypass is illustrated in Figure 1, have main steps that plug-in package 600 It is arranged on the fixture 200 shown in Fig. 4 internal.The operation of this part is from the beginning of reducing assembly 600 so that it is Through inlet container 297, until sealing-plug 607 enters and with the screw-threaded engagement of inlet container 297.Assembly 600 is the position being fully drawn out at that point, and spring clip 615 is fixed on position shown in Figure 11.Overturn close Blocking 607 is until the most fixing, and so sealing between it and inlet container 297 is the most effective.Then Opening gate valve 251, removed by spring clip 615 from axle 601, it is straight that impeller-hub passes through sealing valve 607 Enter to drive hub 605 and seal valve 607.

It will be noted that start the direction faced by handle 603 and the inflow of stopper assembly 609 from accompanying drawing 11 / outflow opening direction is identical.This also is able to make user be placed on by opening 639 on a suitable direction, logical The mode crossing suitable swing handle 603 and then rotation 639 completes.Due to expectation pipeline 100 clogged from And set up the isolation between branch road saddle 109, wherein can produce breaking in bypass, and pipeline in saddle Split 101 and handle 603 should open so that inflow/outflow opening 639 is away from the side rupturing 101 To and towards source of the gas.Axle 601 and stopper assembly 609 use this orientation, drive hub 605 to screw in close In blocking 607, time power axially downwardly enters in fixture 200 and pipeline 100 to axle 601, drive shaft.

Along with axle 601 is constantly pushed into fixture 200, the tip of stopper assembly 609 is pressed into pipeline The bottom of 100, flexure strip 621 and particularly its snaphead 643 deform.Due to elastic head 643 thickness being gradually increased, therefore have sufficient resiliency so that iron clasp 619 cause outside flexure strip and The inner surface of pipeline 100 is consistent.Initial and ensuing flexure strip slight deformation as shown in figure 13, is distinguished Represent with solid line B and dotted line C, and the final position that stopper assembly 609 is in pipeline 100 such as Figure 14 Shown in.In figure it will be seen that between stopper assembly 609 and pipeline 100 wall smile gap or distance The sheet 621 of the stopper assembly through being slightly deformed fills up.As a result, flow ipe 100 through solid before Locking member 200 is also the most all blocked in through pipe section 103 and 105 towards the gas rupturing 101 flowings Pipe section 103 and 105, this is for bypass at two, and the fluid path entering through stopper assembly 609 is consolidated In the mouth 241 of locking member 200.(recall operation as described herein until this operation performed by point all Two fixtures 200 perform, including stopper assembly 609 installation wherein).Cue ball valve 293 are currently and open, so completing the bypass around line sections 10 and 105, the conduit 107 that passes through Extend between cue ball valve 293.The reparation rupturing 101 now begins to execution.

It is interchangeable stopper plug-in package 700 as seen in figs. 15-17.Due to only stopper assembly Difference, so only indicating this part.The stopper assembly 701 of replaceable stopper plug-in package 700 It is characterised by partial cylinder body portion 702, terminates inside Part-spherical head part 703, part 702 He A smooth transition is had, except mold line 705 between the surface of 703.The diameter of two parts 702 and 703 All should wall pipeline 100 interior through smaller.In order to ensure that stopper assembly 701 can stop from branch road saddle Seat the air-flow passed through, the outer seal surface of its partial cylinder body portion 702 is by around main body axis A line more than 180 degree determines.For additional strength and stiffness, stopper assembly is arranged on a heavily fortified point Hard, the most made of iron, on spoon shape clasp 707, the flexure strip 709 of covering has thickening head region 711. Iron clasp 707 has internal screwed clasp 713, at main body and the axis of head 702 and 703 715 centers.Be screwed in clasp 713 is that on axle 601, size reduces, end strips threaded 627. Axle 601 and all remainders of plug-in package, including handle 603, drive hub 605, pin 615 with And sealing-plug 607 and the plug-in package 600 shown in accompanying drawing 11 are all identical.It should be noted that plug-in package The handle 603 of 700 should be towards on a direction predetermined relative to open section 717, such open section 717 Can overturn on airflow direction to be stopped.Interchangeable stopper plug-in package 700 uses and insertion group The mode that part 600 is identical operates.

Replaceable stopper assembly 701 uses the mode similar with stopper assembly 609 to operate.To axle 601 The mode of movement drives and puts in place, and the thickening Hookean region 711 on 703 is compressed so that stop Device assembly can fill full packages road 100 by the way of consistent with its in-profile.

Return to operation order or the operation of interchangeable stopper assembly 701 that stopper assembly 607 inserts Order is a part therein, after repairing leakage 101, is next moved from fixture 200 by plug-in package Remove.Plug-in package 600 with particular reference to accompanying drawing 11-14 is illustrated by this step.This assembly is first by inciting somebody to action Guide wheel hub to outward winding from sealing-plug 607 and shrink, and pull-up handle 603 is until stopper assembly 609 Fully shrinking, such spring leaf 615 can be reinserted in axle 601.It is then shut off gate valve 251, secondary Level ball valve 291 opens release pressure, and whole stopper plug-in package is close by screwing out from container 297 The mode of blocking 607 removes, and then lifts whole assembly 600 and disengages it from fixture 200.

The final step of process is to seal branch road seatpillar the end of a thread 113, is set up by bypass path.Here it is such as The effect of the complete connector plug-in package 800 shown in Figure 18-22.The basic element of character includes pipeline 801, axle 803 Through Pipe transfer, the bottom of spring loaded bracket 805 extension entrance pipeline and a complete connector 807, it is movably attached to the end of the pipeline 801 relative with bracket.It is additionally formed complete connector plug-in package 800 The basic element of character for seal connector 808, be slidably mounted on axle 801.

In general, in the manner hereinafter described, connector 808 is sealed by complete connector insertion group of loweing It is internal that the mode of part 800 is inserted into fixture 200, promotes complete connector 807 until it is locked branch road saddle On seat 109, discharge complete connector 807 from inserting the remainder setting up 800, and from fixture 200 Extract assembly out.

Iron pipeline 801 has a unified external diameter, has the stepped bore of relatively large terminal part 809 And one reduce bore portion 811 from the bore portion 809 omnidistance size arriving pipeline upper end that extends out.Pass through Transition between bore portion 809 and 811 forms shoulder 813, forms the stopping position for helical spring 815, Being compressed between shoulder 813 and nut 817, screw is fastened on reduced size of threaded bar 803 1 End 819.Bracket 805 has one but has the end wall of internal thread hole 821, and wherein the end of thread 819 can enter this Internal thread hole.The order that aforementioned components assembles is bracket 805 and nut 817 is fastened on threaded end 819 On, then one section of nut 817 fastening bracket 805 thus be fixed.Then spring 815 slips over axle 803 Top, and axle is inserted into pipeline 801, through bottom, until bracket 805 enters the bottom of pipeline 801, Then the top of axle 803 is from opposite side, and namely the top of pipeline 801 is stretched out.Block 801 has one Hexagonal head 823 and external screw thread extend 825, be suitable to and the internal thread 827 that mates is at pipeline 801 Tip portion is received.Endoporus 829 is through end cap 821, and just makes the upper of axle 803 through this hole just Hold and dragged expose after pipeline 801 at it.Axle 803 is fixed by handle 831, and handle 831 passes Extend in the hole 833 of axle 803 end and fixed by Alan's head screw 835.

Be cut in pipeline in its bottom is cam groove 837, including one axially, and entrance well part 839 and around extension 841.Cam groove 837 is for being maintained at pipeline 801 by complete connector 807 End, hereinafter will be explained.

Complete connector 807 is made up of resilient disc 843, and elastic plate is the iron plate of iron plate 845 and lower end in upper end Sandwich structure is become between 847.Dish 843 and plate 845 and 847 cross sectional shape are all circular.Bottom surface 847 It is flat.Top board 845 has the upwardly extending cylindrical bosses of Vertical Square 849, wherein extends on radial direction Cam nail 851.Axis in screwed screw 853 extends through plate 845 and 847 and in dish 843 Opening.Be thread through screw 853 one end is nut 855, its size be actually called can with to drive below Bracket 805 adapt.

After the aforementioned components of complete connector 807 has all been assembled, one section of screw 853 hammers 857 thus puts Put harmful the unscrewing and follow-up loss of nut 855 in plug-in package 800 operating process.

Internal by one end of connector 807 being inserted into bracket 805, especially with nut 855, thus will Complete connector 807 is inserted into one section of pipeline 801 until the edge phase of top and bracket 805 of wheel hub 849 Connect.Then connector 807 is pressed to the direction of pipeline 801, so that bracket 805 is pressed into Guan Luzhong, Compression spring 815.The position of cam nail 851 is on wheel hub 849, and so nail will enter cam groove 837, And more particularly, when the upper surface compressing plate 845 connects along 859 with the front of pipeline 801 when, Its periphery 841 can be entered.This represents that piston 807 is fully inserted in pipeline 801, and when reaching The when of this position, piston 807 can turn to, until cam nail 851 falls into and be fixed on peripheral grooves 841 One or another female ends position.When pressure discharges from connector, compression spring 815 can safety Hold it and prevent the end of cam groove 837 from further rotating.It should be noted that, when connector 807 according to The when that described mode being installed, nut 855 at most can be to use the hand-tight mode on bolt 853, so Compression plate 845 and 847 is only subjected only to the power of the least resilient disc 843.This is so that in installation process It is installed to the inside of branch road saddle 109, as mentioned.

Exterior arrangement substantially corresponding on the assembly 600 sealing connector sealing connector 808 is similar to, because It performs to use substantially the same mode when of sealing function.Towards this end, including one six Dihedral head 859 and a cylinder 861 with screw thread 863, cylinder distance 859 is recently and in phase To one end have an O.Axial hole 867 is unified cross sectional shape, prolongs through sealing connector 808 Stretching, size design accommodates pipeline 801 for friction tight mode.Shown detent 869 is just inserted in sealing Above plug 808.

In order to perform seal operation, complete connector plug-in package 800 mode as shown in Figures 18 and 19 assembles, But being the position being completely drawn out, its cam nail 851 is connected with the bottom sealing connector 808, assembly 800 are inserted into fixture 200 inside, and inserted mode is similar with aforementioned operation.Especially, assembly 800 Sealing-plug 808 is screwed into container 297 inside and is fastened and fixed.Hereafter gate valve 251 is opened, and pushes away Dynamic pipeline 801 passes through and seals connector 808 until the end face 873 of detent 869 and connector 808 exists On straight line, as shown in figure 19.Why detent 869 is arranged so that reason is when it is with face 873 Time point-blank, complete connector 807 will be placed on a suitable position in branch road seatpillar road 113 Put.

Along with complete connector plug-in package 800 is fixed on described position, handle 831 can rotate thus cause The rotation of axle 803, also has spring loaded carrier 805 along with what it rotated, and this bracket is positioned at one end of axle 802. In turn, bracket 805 meshes together with the nut 855 of complete connector 807, starts on Neptunea cumingi bolt 853 Nut move, cause the driving to top compression plate 845 to make its fragrant bottom compression plate 847 move.As a result, Resilient disc 843 between plate 845 and 847, is the most gradually compressed, the most in the radial direction Expansion.It is sufficiently large that this process constantly continues until the further rotation of resistance of axle, also indicates that connector 843 The most fully being compressed, the most complete connector 807 can be from remaining of plug-in package 800 Separate on parts, simplely press pipeline 801 and rotate its axial component until cam groove 837 839 with cam nail 851 point-blank, and on this aspect, nail is freely present and the axial component through groove 837 In the line segments of 839.Along with complete connector 807 is positioned, and divide from the remainder of plug-in package 800 Leaving, the remainder of assembly 800 can also be extracted out from fixture 200.In order to realize This move, Pressing up pipeline 801 until bracket 805 is positioned at the top of gate valve 251, valve is to close now, Hereafter secondary ball valve 291 opens release pressure (if present), and by connector 808 will be sealed Unscrew from the position of container 297 and remove assembly 800.

Interchangeable complete connector plug-in package 900 (shows) as shown in figs. 23 and 24 near accompanying drawing 10. All of parts are consistent with plug-in package 800, except the structure of complete connector, at accompanying drawing 23 and 24 In be configured as object 901 and occur.Complete in complete connector in accompanying drawing 8-22 and accompanying drawing 23 and 24 Whole connector difference substantially is that the feature of the latter is to have a resilient disc, and it is positioned at the prominent of metal plug Go out part above and to be overstock with bevelled edge rather than by branch road saddle by branch road saddle The compression of wall and stretching.Especially, complete connector 901 includes a generally cylindrical metal clasp 903, 903 have a threaded main body 905, wherein stretch out a hexagon wheel hub 907.From wheel hub 907 Stretch out cam pin 909, for the function same with the cam pin 851 of accompanying drawing 22.It is threaded clasp main body 905 have the part 911 that a ledge size is gradually reduced, spring caps 913,913 installed above to have One outward flange 915 with inclined plane.In order to accommodate complete connector 901 and with 901 cooperatings, Thering is provided size to reduce part 917 in road seatpillar road 916 and revise its structure, 916 are threaded and clasp Threaded engagement in main body 905.Same, the seat surface 919 with a little faces is at modified branch road saddle The saddle portion 921 of 923 is internal be there is also, as shown in figs. 23 and 24.
