Description
Technical field
The present invention relates to pipe joint unit technology, in particular to a kind of conduit coupling.
Background technique
Generally there are three types of novel pipeline connectors for the connection type of existing plastic conduit: one, bonding method is mainly used for hard
The connection of pvc pipe, ABS pipe, way are to coat binder in bellmouth and socket, and socket is squeezed into bellmouth, and to be bonded dose of solidification is
At the solvent welding agent used is mostly solution of the PVC in tetrahydrofuran or cyclohexanone, it is desirable that modest viscosity, at room temperature most
Low viscosity is 90PaS, and the connection method connection effect is poor, once alite paste thawing will leak.
Two, welding is mainly used for polyolefin pipe, such as LDPE, HDPE and PP pipe, when welding, to the technical requirements of operation compared with
Height, effect are also not fully up to expectations.
Three, it is threadedly coupled, threaded connection is more safe and reliable, but due to screw thread to be opened, the wall thickness of pipe part is with regard to necessary
Thicker than solvent method pipe part, this connection method needs additional process pipeline, and technique is cumbersome, at high cost.
Summary of the invention
The good pipeline connection of simple, at low cost and clamping effect that the technical problem to be solved in the present invention is to provide a kind of structures
Part.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:
A kind of conduit coupling, including valve body and seal assembly, the seal assembly includes that bonnet and sealing block, described close
Envelope card is set between bonnet and valve body；The valve body has symmetrical structure, and one end of the valve body is provided with the first limiting slot
And limiting stand；The bonnet inner sidewall is provided with the second limiting slot；Circlip is provided in second limiting slot；
Retainer ring is additionally provided between the sealing card and bonnet.
Preferably, fixing end is provided in the middle part of the body cavity, the fixing end has chamfering structure.
Preferably, guide table is arranged in the end of the valve body.
Preferably, the sealing card is in conical ring shape, seals lateral surface and the guide table fitting of card.
Preferably, the retainer ring is metal o-ring.
Preferably, one end of the bonnet is in inverted V type.
By adopting the above technical scheme, since the seal assembly includes bonnet and sealing card, the sealing card is set to valve
Between cap and valve body；The valve body has symmetrical structure, and one end of the valve body is provided with the first limiting slot and limiting stand；It is described
Bonnet inner sidewall is provided with the second limiting slot；Circlip is provided in second limiting slot；Between the sealing card and bonnet also
It is provided with retainer ring, so that water pipe joint assembly simplifies traditional structure, reduces production cost, improves the clamping effect of joint assembly
Fruit.
Detailed description of the invention
Fig. 1 is main view of the invention；
Fig. 2 is cross-sectional view of the invention.
In figure, 1- valve body；2- seal assembly；3- bonnet；45- sealing 4 first limiting slots 5 of card；6- limiting stand；7- retainer ring；
8- fixing end；The second limiting slot of 9-；10- circlip.
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Figs. 1-2, a kind of conduit coupling, including valve body 1 and seal assembly 2, seal assembly 2 include 3 He of bonnet
Sealing card, sealing card are set between bonnet 3 and valve body 1；Valve body 1 has symmetrical structure, and one end of valve body 1 is provided with the first limit
Position slot and limiting stand 6；3 inner sidewall of bonnet is provided with the second limiting slot 9；Circlip 10 is provided in second limiting slot 9；Sealing card and
Retainer ring 7 is additionally provided between bonnet 3.
In addition, fixing end 8 is provided in the middle part of 1 inner cavity of valve body, fixing end 8 has chamfering structure.
Further, guide table is arranged in the end of valve body 1, convenient for installing and using for conduit coupling.
In addition, sealing card is in conical ring shape, seals lateral surface and the guide table fitting of card, improves the sealing of conduit coupling
Effect.
Further, retainer ring 7 is metal o-ring, increases the service life of conduit coupling.
In addition, one end of bonnet 3 is in inverted V type, improves the sealing effect of bonnet 3.
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
