Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
Pipeline of the present invention increases the installation method of valve or equipment online, including following workflow:
(1) welding tee pipe:
As it is shown in figure 1, by four tee Ts A, B, C, D, the supervisor's longitudinal center line about 2 along tee T is divided on tee T
Portion 1 and tee T bottom 3, be installed on pipeline 25 by tee T top 1 and tee T bottom 3 and design position, be wrapped in pipe respectively
Outside road 25, it is respectively welded with pipeline 25；After installing, tee T A, B are positioned at the left side of pipeline 25 valve location to be increased,
Tee T C, D are positioned at the right side of pipeline 25 valve location to be increased.
(2) flap type is installed:
As in figure 2 it is shown, be respectively mounted flap type 4 at the upper flange of tee T A, B, C, D, install flap type 4 and keep
Closed mode, waits hole to be drilled；Described flap type 4 can be opened flashboard 6 by handwheel 5 and realize opening and closing.
(3) closed rig is installed:
As it is shown on figure 3, described closed rig is installed on the valve flange upper surface of flap type 4, closed rig
Including the drilling rod 10 being arranged in bell jar body 8, boring dish 7, sealed packing 9, seal for pipe joints plug 15 etc., bell jar body 8 times
End face is installed on the valve flange upper surface of flap type 4 by sealing ring and flange bolt nut, and drilling rod 10 is by bell jar body 8
It is internal that bell jar body 8 is stretched on top, sets sealed packing 9 and seal for pipe joints plug 15 between drilling rod 10 and bell jar body 8, drilling rod 10
Bottom arranges boring dish 7, and the upper end of drilling rod 10 is power intake, can connect motor or reductor equal power device；
Automatically rotate after drilling rod 10 input power, drive boring dish 7 milling cutter to rotate, tee T lumen correspondence portion outside pipeline 25
Position carries out perforate, after perforate completes, exits boring dish 7(drilling rod 10 top and is provided with aperture a, realize carrying of drilling rod 10 by aperture a
Rise and exit) in bell jar body 8 inner chamber, turn off flap type 4, prevent medium from leaking；So operation, is respectively completed four threeways
Boring at pipe；In Fig. 3, shadow region b is boring cutting area.
(4) bypass duct is installed:
As shown in Figure 4, after closing flap type 4, it is respectively welded installation shunt valve in upper flat plate valve 4 upper surface of tee T A and D
Road 26.
(5) installing stopper valve module:
After bypass duct 26 construction, open the flap type 4 at tee T A and D, allow medium pass through from bypass duct 26；Inspection
Look into after confirming to close the flap type 4 at tee T B and C, take the boring dish 7 within closed rig apart, be replaced by plug valve
Assembly.As it is shown in figure 5, plug valve assembly include being arranged in bell jar body 8 seal for pipe joints plug 15, sealed packing 9, sealing ring
14, push rod 16, rotating shaft 11 and piston body 13, it is internal that push rod 16 is stretched into bell jar body 8 by the top of bell jar body 8, push rod 16 with
Arranging seal for pipe joints plug 15 and sealed packing 9 between bell jar body 8, the lower end of push rod 16 connects piston body 13 by rotating shaft 11,

Put stopper slot 17, keep the directional-rotation of piston body 13；
When starting to construct, opening the flap type 4 at tee T B, C, piston body 13 is entered from bell jar body 8 inner chamber by push rod 16
The bottom of pipeline 25, due to the bottom guide effect of roller 12, piston body 13 slides to left side automatically (herein for upstream to break away
Dynamic), the rotational angle of piston body 13 is limited by push rod 16 lower limit groove 17, and therefore piston body 13 can be accurately positioned, close
After the contact internal walls of seal 14 and pipeline 25, it is possible to achieve the closing isolation of medium in pipeline 25；With the most contrary, tee T C
The plug valve installation direction at place, for pushing downstream to, mainly prevents medium from flowing backwards.
(6) installation targets valve or equipment:
As shown in Figure 6, the plug valve assembly at tee T B, C is installed after putting in place, and cutting pipeline 25 between tee T B, C is installed
Target valve or equipment 27；Now guaranteeing that the flap type 4 of bypass duct 26 is opened, plug valve is correctly closed and is put in place.Consider before cutting
Media type and middle part residual stress, as poisonous and harmful medium, it is contemplated that before construction, install small-sized pressure release drain valve in advance.
(7) plug valve assembly is removed, replacing blind plate assembly:
After target valve or equipment 27 install, by push rod 16, piston body 13 is return bell jar body 8 inside, close threeway
Flap type 4 at pipe B, C；Then by plug valve assembly on flap type 4 side flange disintegrate after, change plug valve assembly be blind plate group
Part；As it is shown in fig. 7, described blind plate assembly include being arranged in bell jar body 8 blind plate 19, blind plate push rod 18, blind plate sealing circle
20, sealed packing 9 and seal for pipe joints plug 15, it is internal that blind plate push rod 18 is stretched into bell jar body 8 by the top of bell jar body 8, blind plate
Arranging seal for pipe joints plug 15 and sealed packing 9 between push rod 18 and bell jar body 8, the lower end of blind plate push rod 18 uses screw thread with blind
Plate 19 connects, it is simple to blind plate 19 disintegrates after putting in place, and the centrally disposed female thread in blind plate 19 upper surface, outside blind plate push rod 18 lower end is arranged
Screw thread, rotates blind plate push rod 18 and can realize the disintegration of blind plate 19 and blind plate push rod 18；In the outside of described blind plate 19, blind plate is set
Sealing ring 20, realizes the sealing between blind plate 19 and tee T lumen sidewall after compression.
During Specific construction, after having assembled blind plate push rod 18 and blind plate 19, by bell jar body 8 by sealing gasket and bolt spiral shell
Mother is installed on end face of flange on the upside of flap type 4, opens lower flat plate valve 4, by blind plate push rod 18, blind plate 19 is advanced tee T
Lumen, after putting in place, rotate blind plate push rod 18, make blind plate push rod 18 disintegrate with blind plate 19.Blind plate 19 at tee T B is installed to
After Wei, carry out blind plate 19 installation at tee T location of C；When finally carrying out the construction at tee T A, D, during construction, note
After meaning closes the flap type 4 at tee T A, D, remove bypass duct 26.
(8) bell jar accessory and flap type are removed:
As shown in Figure 8, after blind plate 19 puts in place, remove the bell jar accessory at three-way valve A, B, C, D and flap type.Consider safe because of
Element, can install sealing gasket 24 and lumen flange 23 after the dismounting of each position flap type immediately, and tight a bolt 22 nut 21(such as Fig. 9
Shown in).
(9) completion detection:
Construction terminates, and in detection everywhere, whether at flange seal and commissure leaks.
The operation principle of the present invention is: pipeline upstream and downstream installs four tee Ts altogether, be respectively used to outside bypass interface and
Inner side isolation closed interface.Each tee T cuts apart into upper and lower two halves from channel middle, facilitates and welds envelope after duct wraps
Close；Tee T lumen flange installs flat board isolating valve, for isolating isolation and the replacing instrument of construction accessory and medium.Flap type
Top installation bell shape accessory, accessory possesses boring, installs plug valve and exit plug valve, the function of installation blind plate.Flap type
After opening, above-mentioned boring, plug valve is installed and exits plug valve, the operation such as blind plate is installed implements step by step.Complete closedown respectively of constructing is put down
Plate valve, it is ensured that medium does not leaks.Change instrument simultaneously, complete each operation.Final flap type and the bell shape accessory removed, installation three
Logical flange, completes construction.
