Abstract
The present invention discloses a kind of bell and spigot joint, is made of pin end and female connector, sealing strip is set on the madial wall of female connector, and warping part, warping part direction water inlet direction are formed in the end of sealing strip；In pin end insertion female connector, pin end insertion end forms tapered, and sealing strip is close on tapered insertion end outer wall.The present invention is quickly and expediently installed, and hydraulic pressure is bigger and closure is better.
Description
Technical field
The present invention relates to a kind of bell and spigot joints, and it is suitable for pipeline connections.
Background technology
PVC winding pipe is widely used in municipal drainage, blowdown, flood discharge and agricultural irrigation diversion, in the prior art, PVC
Connection between winding pipe is usually pyrocondensation band connection, the formula connection of fiberglass Harvard, and liner connection and stainless is embraced outside epoxy resin
Steel hoop formula connects, however, being the defects of the connection mode：
Installation is inconvenient, complex process, and the installation Connection Time is long, and security is poor, and pipeline junction ring stiffness, which is not achieved, to be set
Meter requires, and the junction between pipeline easily disconnects, flattens, and causes leak, and leak be easy to cause Subgrade Subsidence, influences
Pipeline engineering quality.
In view of this, the present inventor develops a kind of bell and spigot joint, and to overcome the defect, thus this case generates.
The content of the invention
It is an object of the invention to provide a kind of bell and spigot joints, are quickly and expediently installed, and hydraulic pressure is bigger and closure more
It is good.
To reach above-mentioned purpose, solution of the invention is：
A kind of bell and spigot joint, is made of pin end and female connector, and sealing strip is set on the madial wall of female connector, is sealing
The end of item forms warping part, warping part direction water inlet direction；In pin end insertion female connector, pin end insertion end is formed with cone
Degree, sealing strip are close on tapered insertion end outer wall.
Further, the sealing strip is arranged on the madial wall of female connector and forms mounting portion, and the thickness of sealing strip is by pacifying
Dress portion to warping part is gradually thinning.
Further, the sealing strip includes back side and upstream face, and warping part is formed in upstream face and back side junction,
Back side is arranged to arcwall face, and upstream face is arranged to arcwall face or is plane.
Further, installation groove is formed on the madial wall of the female connector, the sealing strip is arranged in installation groove.
After using the above program, in the use of the present invention, pin end and female connector difference connecting pipe, pin end insertion are female
In connector, pin end insertion end forms tapered, and sealing strip is close on tapered insertion end outer wall, in the end of sealing strip
Form warping part, warping part direction water inlet direction.Therefore, have in the duct current by when, the pressure extrusion sealing strip of current
Warping part brings it about flexible deformation, and sealing strip warping part is close on the tapered insertion end outer wall of pin end, plays closing
Effect, moreover, when hydraulic pressure is bigger, the elastic deformation that sealing strip warping part occurs is bigger, and there is cone in sealing strip warping part with pin end
The insertion end outer wall fitting of degree is closer, and closure is better.
Meanwhile the present invention is made of pin end and female connector, and it is simple in structure, it is quickly and expediently installed, without professional
It can be installed.

Specific embodiment
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
Refering to a kind of bell and spigot joint that shown in Fig. 1 to Fig. 4, the present invention discloses, it is made of pin end 1 and female connector 2.
Sealing strip 3 is set on the madial wall of female connector 2, and sealing strip 3 is usually rubber strip, in the present embodiment, described
Installation groove 21 is formed on the madial wall of female connector 2, the sealing strip 3 is arranged in installation groove 21.In the end of sealing strip 3
Warping part 31 is formed, towards water inlet direction, the thinner thickness of the warping part 31 elastic deformation easily occurs for warping part 31.
Pin end 1 is inserted into female connector 2, and 1 insertion end 11 of pin end forms tapered, and sealing strip 3 is close to tapered
On 11 outer wall of insertion end.Have in the duct current by when, 3 warping part 31 of pressure extrusion sealing strip of current brings it about bullet
Property deformation, 3 warping part 31 of sealing strip is close on tapered 11 outer wall of insertion end of pin end 1, plays sealing process, moreover,
When hydraulic pressure is bigger, the elastic deformation that 3 warping part 31 of sealing strip occurs is bigger, and 3 warping part 31 of sealing strip and pin end 1 are tapered
The fitting of 11 outer wall of insertion end is closer, and closure is better.
As shown in figure 4, the sealing strip 3 is arranged on the madial wall of female connector 2 and forms mounting portion 32, sealing strip 3
Thickness is gradually thinning by mounting portion 32 to warping part 31 so that when current pass through crush seal item 3,3 elastic deformation of sealing strip is more
To be easy, so that 3 warping part 31 of sealing strip insertion end 11 outer wall tapered with pin end 1 is bonded more close, closing
Property is more preferable.
The sealing strip 3 includes back side 33 and upstream face 34, is formed and tilted in upstream face 33 and 34 junction of back side
Portion 31, back side 33 are arranged to arcwall face, and to enhance the elasticity of sealing strip 3, and upstream face 34 can be arcwall face, or
Plane or other shaped faces.
In the use of the present invention, pin end 1 and female connector 2 distinguish connecting pipe, pin end 1 is inserted into female connector 2, public access
First 1 insertion end 11 forms tapered, and 3 warping part 31 of sealing strip is close on tapered 11 outer wall of insertion end, 31 court of warping part
To water inlet direction.The present invention is made of pin end 1 and female connector 2, simple in structure, is quickly and expediently installed, without professional
It can be installed.
The foregoing is merely one embodiment of the present of invention, and not to the limitation of this case design, all designs according to this case are closed
The equivalent variations that key is done each fall within the protection domain of this case.
