Description
Technical field
This utility model relates to pipeline through-wall technical field of sealing technology, particularly relates to a kind of wall feed-through pipeline sealing device.
Background technology
In daily life, or job site, wall feed-through pipeline is the most common, but common wall feed-through pipeline uses bushing type
Sealed waterproof device, this structure is the most more complicated, needs to use a series of parts such as seal ring, back-up ring, rubber ring, and
When the stroke of pipeline is bigger, the sealing structure of upstream face can be subject to the biggest challenge, does not has pretightning force, seal pressure to be difficult to hold
Setting up for a long time, durability is the lowest；So using a kind of good airproof performance, durability is strong, and structure simple wall feed-through pipeline again seals
Device is always the problem that people pay close attention to very much.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, can go very easily to use wall feed-through pipeline skill
Art, and a kind of wall feed-through pipeline sealing device is provided, this apparatus structure is simple, uses spheroidal graphite cast-iron casting to form casing flange, saves
Removing seal ring, corrosion resistance is high, the better tightness of package unit.
The purpose of this utility model is achieved by the following measures: a kind of wall feed-through pipeline sealing device, including through
The wall pipe of concrete wall, casing flange and split flange, described casing flange is socketed on wall pipe and is installed on body of wall
In, described split flange is installed on the upstream face of concrete wall and the junction of wall pipe and is socketed on wall pipe, institute
State split flange to contact with the joint face of casing flange.
Preferably, described casing flange is that spheroidal graphite cast-iron casting forms.
Preferably, the length of described casing flange is equal with the thickness of the concrete wall passed, casing flange chamber
The external diameter of body and the equal diameters of the through hole of concrete wall.
Preferably, the internal diameter of described casing flange is equal with the external diameter of wall pipe.
Preferably, the joint face of the casing flange of described upstream face and the contact surface of split flange scribble special modified poly-
Urethane.
Preferably, described split flange is two symmetrical semicircular ring, and split flange contacted with wall pipe interior
Wall scribbles special modified polyurethane.
Preferably, two semicircular ring are tightly fastened by described split flange by bolt.
The beneficial effects of the utility model are: this utility model simple in construction, use spheroidal graphite cast-iron casting to form tiretube process
Orchid, saves seal ring, and corrosion resistance is high, and the joint face of casing flange and the contact surface of split flange scribble special modified poly-
Urethane, the inwall that split flange is contacted with wall pipe is also coated with special modified polyurethane, and special modified polyurethane runs into air
In aqueous vapor after can automatic foaming, be inflated all of space, the sealing of this structure can be more preferably.
Accompanying drawing explanation
Fig. 1 is the overall sectional view of wall feed-through pipeline sealing device.
Fig. 2 is the structural representation of casing flange.
Fig. 3 is the structural representation of split flange.
In figure: 1-concrete wall, 2-wall pipe, 3-upstream face, 4-casing flange, 5-split flange, 6-is special modified
Polyurethane, 7-bolt.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, this utility model is made further
Describe in detail.
Embodiment 1: as shown in Figure 1, Figure 2, Figure 3 shows, a kind of wall feed-through pipeline sealing device, there is wearing through concrete wall 1
Wall coil 2, casing flange 4 and split flange 5, casing flange 4 is socketed on wall pipe, is then fitted in body of wall, this tiretube process
Blue casting for spheroidal graphite cast-iron forms, because being cast iron, phosphorus content dealings is more than 4.7%, and resistivity is high, corrosion-resistant, Transducers Embedded in Concrete
Before, outer surface shot-peening roughening treatment, seal ring is set such that it is able to save, the length of casing flange and the concrete walls passed
The thickness of body is equal, the equal diameters of the external diameter of casing flange cavity and the through hole of concrete wall, the internal diameter of casing flange with
The external diameter of wall pipe is equal；Split flange 5 is arranged on the upstream face 3 of concrete wall 1 and the junction of wall pipe 2 and is socketed in
On wall pipe 2, split flange 5 contacts with the joint face of casing flange 4, and split flange 5 is two symmetrical semicircular ring, and right
The inwall that therapy of waking up the patient from unconsciousness blue 5 is contacted with wall pipe 2 scribbles special modified polyurethane 6, and the joint face of the casing flange 4 of upstream face is with right
The contact surface of therapy of waking up the patient from unconsciousness orchid 5 is also coated with special modified polyurethane 6, and special modified polyurethane 6 can be automatically after running into the aqueous vapor in air
Foaming, is inflated all of space, and with periphery material bonding very well, will not shrink disengaging, have good elasticity；To therapy of waking up the patient from unconsciousness
Two semicircular ring are tightly fastened by blue 5 by bolt 7；By the device after improving, simple in construction, good endurance, reliability is high,
Being convenient for changing, good seal performance, self sealss act on jointly with strength seal, effective.
