Aperture wiring refers in the case where not stopping original pipeline pumped (conveying) medium, to pipeline tapping, branch spool is installed, in PE
In the aperture wiring construction of pipe, most of applied currently on the market is that saddle-type pipe is occupied with small-bore wiring tee pipe fitting is connect
It is more, it is less as connecing bigbore wiring tee pipe fitting, it can not meet and connect branch line use, the rack on existing market is usually original small
The structure of bore diameter carries out size amplification, and existing market upper spider designs no side plate, will cause accident potential in use, greatly
Rate-of flow is big in bore PE pipe, and pressure is high, and original structure is easy to appear accident.
Utility model content
The utility model against the above deficiency, proposes a kind of PE pipeline rack for connecing branch line, by lengthening side plate, subiculum
Plate, radius snap ring, valve body composition, can satisfy various different tube diameters and connect branch line function, greatly improve safety in utilization and reliable
Property.
The utility model product is characterized in that the fixation for solving to connect branch line for PE electric smelting tee pipe fitting, and can be in machine
Aperture, lower stifled function are realized on frame.The purpose of this utility model, including fan-shaped gate valve, upper company can be achieved by following develop
Connect a few part compositions such as disk, lower sealing flange, plate supported on both sides, variable diameter snap ring, balance bleeding device.
This practical effect is to convert variable diameter snap ring, is a semi arch plate being connected between side plate and caliber,
Different variable diameter snap rings is matched according to caliber difference, connects branch line use to meet different calibers.
Detailed description of the invention
Fig. 1 is a kind of PE pipeline wiring rack half section schematic of the utility model embodiment.
Fig. 2 is the side view of the utility model embodiment.
Fig. 3 is Fig. 1 centre circle A schematic diagram.
Legend: upper terminal pad 1, valve body 3, side plate 4, fan-shaped flashboard 5, lower sealing flange 6, clamping bar 7, is fitted at balanced valve 2
Orchestration 8, radius snap ring 11, lower pallet 12, screw rod 92, lower saddle support 91.
Specific embodiment
The utility model is described in detail below with reference to specific embodiments and the drawings.
A kind of PE pipeline wiring rack is shown referring to FIG. 1-2, mainly include upper terminal pad 1, balanced valve 2, valve body 3,
Side plate 4, fan-shaped flashboard 5, lower sealing flange 6, clamping bar 7, adapter 8, radius snap ring 11, lower pallet 12；In upper terminal pad 1
End face mainly connect with tapping machine, means for placing plug equipment, lower end surface links together with valve body 3, the lower end surface of upper terminal pad 1 and
3 contact surface of valve body has seal with O ring.One balanced valve, 2 device is housed on valve body 3, is penetrated through with valve body 3, plays balance pressure
Effect, have one piece of fan-shaped flashboard 5 among valve body 3, fan-shaped flashboard 5 is the opening and closing movable part of valve body 3, is opened with spanner fan-shaped
Flashboard 5 plays the role of controlled valve, and 3 lower end of valve body is connect with lower sealing flange 6, has seal with O ring in junction, under
Sealing flange 6 is lower to be connected from different adapters 8, can be applied to different tube diameters, and adapter 8 is lower to be connect with wiring tee pipe fitting 9,
There is seal with O ring, wiring tee pipe fitting 9 is fixed on PE pipeline 20, by screw rod 92 and lower saddle support 91 in the two sides of valve body 3
Face is provided with side plate 4；Valve body 3 is fixed on pipeline by clamping bar 7 from different radius snap rings 11 and lower pallet 12 by side plate 4
On, wiring tee pipe fitting 9 is erected on PE pipeline 20, and lower section is held with lower saddle support 91, the contact surface of such wiring tee pipe fitting 9
Product is bigger.
If Fig. 2 illustrates the structure of clamping bar 7, lower pallet 12 is located at the lower section of PE pipeline 20, and radius snap ring is arranged in top
11, clamping bar 7 is fixed in which can be convenient with bolt, can by adjusting the length of clamping bar 7 for side plate 4 above clamping bar 7
To utilize 7 fixed side panel 4 of clamping bar well, since heavy caliber PE effective valve body 3 is than heavier, while PE pipe has certain change
Type amount, can preferably fixed valve body 3 by clamping bar 7.
The effect of adapter 8 is to connect wiring tee pipe fitting 9 and valve body 3, while connecing according to different pipe fittings
Line tee pipe fitting 9 is adjusted.
Such as Fig. 3, the enlarged diagram of side plate 4 is illustrated, side plate 4 is mounted on valve body 3 by two bolts 41, is blocked simultaneously
The side of valve body 3 is lived, such valve body 3 is stronger.
Such as Fig. 1, clamping bar 7 is provided with two sets, and front and back is all arranged a set of on pipeline, clamps in this way, forming a front and back
Structure, stronger, correspondingly, side plate 4 also has two sets.
The work flow of the present apparatus is: cleaning out needing replacing pipeline section, i.e. welding position, by wiring tee pipe fitting 9
It is welded on welding position, connects electro-fusion welding machine power supply, adapter 8 is connected on wiring tee pipe fitting, uses spanner by fusion weld
Fastening opens fan-shaped flashboard 5 in rack, rack is placed in main pipe, the lower pallet 12 of rack two sides is inserted into below rack,
