Description
Technical field
The utility model relates to a kind of work well sealing pipe fitting, especially a kind of work well antipriming pipe with bellows piece
Part.
Background technique
Underground electric pipe network is connect by piping lane with work well by piping lane and work well construction, cable protection pipe, the electricity in piping lane
The shape of cable protection pipe has walled tube, also there is bellows, and material is mostly the thermoplastics such as polypropylene, polyethylene, cable protection
The connection construction of Guan Yugong well, it is necessary to ensure that it is close, it is water-tight and easy for construction.Traditional way is to block electricity with concrete
Gap between cable protection pipe and work well, since the deformation rate of concrete and cable protection pipe is different, when generation ground settlement
When, easily generate leakage.If work well is connect with cable protection tubing using connector made of hot melt material merely, end
Hot-melt adhesive paste needs operate in piping lane, and construction operation space is small, and not easy to operate, the utility model designs a kind of work well sealing
Pipe fitting uses thermoplastic for main material, and end is equipped with bellows piece, both can ensure that connection sealing, and construct just
It is prompt.
Summary of the invention
The purpose of the utility model is to provide a kind of work well sealing pipe fitting with bellows piece, both facilitates cable protection
The connection of Guan Yugong well, connection sealing are again close.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of work well with bellows piece is with stopping
Pipe fitting, including horn mouth (1), limit plate (2), planomural pipeline section (3), bellows piece (4) and sealing ring (5), it is characterised in that
The horn mouth (1) setting is described planomural pipeline section (3) one end in one end of the planomural pipeline section (3) and formed integrally
Open out extension, the bellows piece (4) is inner wall planomural pipeline section (41) and outer wall bellows piece (42) hot-melt adhesive paste is
The double-wall corrugated pipeline section of one, the inner wall planomural pipeline section (41) setting the planomural pipeline section (3) the other end and with its shape
Integrally, the outer wall bellows piece (42) is alternately made of concave arc (421) and dome arc (422), the concave arc
(421) cross sectional shape is U-shaped, and dome arc (422) section is n shape, and is to terminate section with dome arc (422)；The limit
Plate (2) be looped around on the outer tube wall of the planomural pipeline section (3) between the horn mouth (1) and the bellows piece (4) and with
One is formed, the sealing ring (5) is looped around planomural pipeline section (3) outside, is located at the limit plate (2) and the bellows
Between section (4) and abut the limit plate (2)；The sealing ring (5) is water-swellable sealing ring；The horn mouth (1), limit
Position plate (2) and sealing ring (5) are placed in the work well borehole wall, and the bellows piece (4) is placed in outside work well and is located in piping lane, are passed through
Pipe collar connect with bellows or connect with the walled tube for being welded with bellows piece.
Utility model has the advantages that 1, by limit plate, increase the path that water flow penetrates into work well, and pass through
Water-swellable sealing ring significantly reduces work well seepage of water.
2, by bellows piece, and pipe collar is combined, facilitates sealing pipe fitting to connect with the tubing in piping lane, quick construction can
It leans on.
Detailed description of the invention
Fig. 1 is a kind of sectional view of the work well sealing pipe fitting with bellows piece of the utility model.
Fig. 2 is a kind of connection installation diagram of work well sealing pipe fitting and ripple with bellows piece of the utility model.
Fig. 3 is a kind of connection installation diagram of the work well sealing pipe fitting with bellows piece and walled tube of the utility model.
Specific embodiment
As shown in Figure 1, a kind of work well sealing pipe fitting with bellows piece, including horn mouth (1), limit plate (2),
Planomural pipeline section (3), bellows piece (4) and sealing ring (5), it is characterised in that the horn mouth (1) is arranged in the planomural pipeline section
(3) one end is simultaneously formed integrally, is the open out extension of described planomural pipeline section (3) one end, and the bellows piece (4) is
The double-wall corrugated pipeline section that inner wall planomural pipeline section (41) and outer wall bellows piece (42) hot-melt adhesive paste are integrated, the inner wall walled tube
Section (41) setting is in the other end of the planomural pipeline section (3) and formed integrally, and the outer wall bellows piece (42) is by recessed circle
Arc (421) and dome arc (422) alternately form, and concave arc (421) cross sectional shape is U-shaped, dome arc (422) section
It for n shape, and is to terminate section with dome arc (422)；The limit plate (2) is looped around the horn mouth (1) and the bellows piece
(4) on the outer tube wall of the planomural pipeline section (3) between and with formation integrally, the sealing ring (5) is looped around the walled tube
Section (3) is external, between the limit plate (2) and the bellows piece (4) and abuts the limit plate (2)；The sealing
Enclosing (5) is water-swellable sealing ring.
As shown in Fig. 2, the horn mouth (1), limit plate (2) and sealing ring (5) are placed in Gong Jing when the utility model is installed
In the borehole wall, the bellows piece (4) is placed in outside work well and is located in piping lane, can be connect with bellows by pipe collar.
As shown in figure 3, walled tube is connected one end bellows in piping lane external hot melting in advance, i.e., when connecting with walled tube
It can be connect using pipe collar with bellows piece in piping lane.
