Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Wherein identical components are presented with like reference characters.It should be noted that word used in the following description
Language "front", "rear", "left", "right", "up" and "down" refer to the direction in attached drawing, word " bottom surface " and " top surface ", "inner" and
"outside" refers respectively to the direction towards or away from geometric center of specific component.
A kind of FRP sand tube bell and spigot bend, as shown in Figure 1, include in bending setting tube body 1, the one of tube body 1
Integrally formed with socket 2, the other end can be inserted in adjacent pipeline integrally formed with bellmouth 3, socket 2 at end.Socket 2 connects
Have the seal assembly 4 of the clearance seal between pipeline and socket 2, seal assembly 4 include be socketed on 2 lateral wall of socket be in
The sealing ring 41 of sky setting, the air inlet pipe 42 inflated into sealing ring 41 and the check valve 43 for limiting airflow direction.Sealing ring 41
It for rubber material, is adhered with air inlet pipe 42, and air inlet pipe 42 is connected to the inner cavity of sealing ring 41.Check valve 43 and air inlet pipe 42
Coaxial arrangement, and check valve 43 is connected towards 41 direction of sealing ring.When being installed pipeline and elbow, directly by elbow
Socket 2 is inserted into pipeline, is inflated later by air inlet pipe 42 into sealing ring 41, so that sealing ring 41 be made to expand, utilizes sealing
Circle 41 is by the gap filling between pipeline and the socket 2 of elbow, and elbow and pipeline are installed at this time, reduces operation step
Suddenly, working efficiency is increased.
In order to avoid sealing ring 41 from generating movement in pipe laying and when elbow, make sealing ring 41 and socket 2 without departing from,
As shown in Fig. 2, 2 lateral wall of socket coaxially offers recessing groove 21, sealing ring 41 can be placed in recessing groove 21.Pass through recessing groove 21
Making the position of sealing ring 44 will not change, and be disconnected sealing ring 41 will not with socket 2, to make the installation of elbow more
Add conveniently.
As shown in Fig. 2, will cause sealing ring 41 at this time since pipeline and elbow can generate relative movement in use
Abrasion, influences the service life of sealing ring 41, while sealing ring 41 can also be made to generate gas leakage.Therefore sealing lateral wall is coaxially adhered
There is sealing ring 44, sealing ring 44 is rubber material.Make sealing ring 41 will not directly and tube contacts, to make by sealing ring 44
Sealing ring 41 will not generate abrasion, increase the service life of sealing ring 41.
As shown in Fig. 2, since pipeline and elbow can relatively move in use, sealing ring 44 and sealing at this time
The relative position of circle 41 can change, and the direction for the power that the sealing ring 41 that sealing ring 44 is subject to applies changes, to reduce
The contact area of sealing ring 44 and inner wall of the pipe influences the effect of sealing.Therefore 41 inner wall of sealing ring is fixedly connected with support ring
45, support ring 45 is circumferential to be connected with several guidance sets 5, and guidance set 5 includes being adhered in the fixed link of 45 lateral wall of support ring
It 51 and is adhered in the guide rod 52 of 45 outer wall of support ring.Fixed link 51 coaxially offers guide groove far from the end face of sealing ring 44
511, guide rod 52 can be inserted in sliding in guide groove 511.Using the cooperation between guide rod 52 and fixed link 51, make sealing ring
Relative position between 44 and sealing ring 41 will not change, to make the contact area between sealing ring 44 and inner wall of the pipe
It will not change, and then the sealing effect of sealing ring 44 is made not change.
As shown in Figures 2 and 3, after long-time use due to sealing ring 41, gas leakage can be generated and generates contraction, this
When sealing ring 44 can be detached from the connection with inner wall of the pipe.Therefore guide rod 52 connects the limitation component 6 of its restricted movement, limitation
Component 6 includes connecting to abut block 61 and abut the spring 62 mobile far from guide rod 52 of block 61 for pushing with guide rod 52.It leads
To 52 side wall of bar offer with the holding tank 521 that abuts block 61 and cooperate, abutting block 61 can be placed in holding tank 521 and moves, and abut
Block 61 offers lozenges 611 far from the end face of guide rod 52, and lozenges 611 is close to one end of 2 axis of socket direction guiding
The inclination of 52 direction of bar.Spring 62 is placed in holding tank 521, and one end is abutted with holding tank 521, and the other end is leaned on block 61 is abutted
The end face of nearly guide rod 52 abuts.51 side wall of fixed link, which runs through, several abutting slots 512 being axially arranged along it, abuts slot 512
It can be connect with holding tank 521, abutting block 61 can be inserted in abutting slot 512.Make guide rod 52 and fixed link using limitation component 6
The distance between 51 will not change, to make sealing ring 44 that can keep the abutting with inner wall of the pipe, make making for sealing ring 44
Stablized with holding.Simultaneously when the inner diameter of 1 bellmouth 3 of tube body generates subtle variation, in sealing ring 44 and 1 bellmouth 3 of tube body
Its outer diameter can change when wall abuts, and limit component 6 at this time and remain to play support to sealing ring 44.
As shown in Figure 1, the position of the air inlet pipe 42 during installation can not determine due to elbow and pipeline, will lead into
Tracheae 42 generates distortion and is broken.Therefore 2 lateral wall of socket is fixedly connected with link block 7, end face of the link block 7 far from socket 2
The link slot 71 cooperated with air inlet pipe 42 is offered, link slot 71 runs through the two sidewalls of link block 7, and air inlet pipe 42 can the company of being placed in
Clamping in access slot 71.The position of air inlet pipe 42 is determined by link block 7, thus distort air inlet pipe 42 will not during installation,
Air inlet pipe 42 will not be broken.The position of air inlet pipe 42 is easier to determine simultaneously, using more convenient when air inlet pipe 42.
Working principle:
The socket 2 of elbow is inserted into pipeline, is inflated later by air inlet pipe 42 into sealing ring 41 by inflator, it is close
The expansion of seal 41 abuts sealing ring 44 with inner wall of the pipe, and guide rod 52 and fixed link are driven during sealing ring 41 expands
51 away from each other, is clamped later using abutting block 61 with slot 512 is abutted, makes sealing ring 44 that can keep the abutting with inner wall of ring body,
Air inlet pipe 42 and link slot are clamped later, the connection of elbow and pipeline is completed at this time.
Specific embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
