Abstract
The utility model discloses a novel sealing connecting device of a composite tube fitting, which is composed of a locking nut 2, an opening locking clamping ring 3, a connecting post tube 4 and a sealing ring 5, wherein, a single side of the section of which is in an L shape. The utility model has the characteristics of simple structure, low cost, convenient installation, good sealing effect, etc., and is an ideal sealing connecting device of various water supply tube especially composite tube and engineering plastics tube fittings.
Description
The utility model relates to the connection fittings that a kind of water pipe is used, particularly a kind of novel seal connection set of composite pipe accessory.
At present, composite running water pipe has begun to apply at home, but the amplitude of promoting is little, and its main cause has the following aspects: the one, mostly adopt the copper material of doing, and complex structure, manufacturing procedure is many, the expense height, and exist the pollution problem of secondary copper; The 2nd, its sealing with in the annular groove of " O " RunddichtringO device on the inner cylinder of attachment post tube cavity " U " shape groove, the overcoat connected tube, the grip force that utilizes slotted collar to produce shrinks connected tube to realize and seals, thereby its sealing effect is not very good; The 3rd, in recent years, though there are some producers to develop to mould the overall plastic accessory for copper, it sealed as hereinbefore, so sealing effect is still not good.
The purpose of this utility model provide a kind of simple in structure, cost is low, the novel seal connection set of the composite pipe accessory of easy for installation, good sealing effect.
The purpose of this utility model is achieved like this: be that connection column jecket 4 by locking nut 2, opening shackle 3, inner chamber band " U " shape groove 6 constitutes, connected tube 1 be connected between the column jecket 4 monolateral L-shaped seal ring 5 in cross section in addition.
The inner cylinder 7 of " U " shape groove 6 is a conical surface.
The novel seal connection set of composite pipe accessory of the present utility model will have annular groove on the inner cylinder of " U " shape groove now and save and change conical surface into, like this since, both simplified its structure, save the machining of annular groove again, also reduced cost; Simultaneously, because the inner cylinder of " U " shape groove adopts conical surface, be convenient to pierce into the endoporus of connected tube on the one hand, the convenient installation, the endoporus of connected tube is pressed on the conical cylinder of " U " shape groove under the promotion of locking nut and shackle on the other hand, forms the sealing of first road; And the port of connected tube is pressed on the bottom surface of " L " shape seal ring, forms the sealing of second road; The end outer cylinder of connected tube also is pressed on the inwall of " L " shape seal ring under the expansive force effect of the conical cylinder of " U " shape groove, thereby has formed three seals.Thereby the sealing effect of the novel seal connection set of composite pipe accessory of the present utility model is fine.
Accompanying drawing 1 is a main sectional view of the present utility model.
Below in conjunction with accompanying drawing, describe an embodiment of the present utility model in detail.
Present embodiment is to be made of locking nut 2, opening shackle 3, connection column jecket 4 and the monolateral L-shaped seal ring 5 in cross section.
The cross section of locking nut 2 is hat, and the outside is a polygonal, and middle porose, its underpart is an inner bolt hole.
Opening shackle 3 is the annulus that a cross section is semicircle shape, and an inclined open is arranged on the ring wall.
The first half that connects column jecket 4 is a hollow cylinder, and its inwall has short " U " shape groove 6, and the inner cylinder 7 of groove 6 is a conical surface, the outer Luo line that has the internal thread with nut 2 to match on the external cylindrical surface of column jecket 4; The lower half portion 8 that connects column jecket 4 can be and its upper half part identical construction, also can be outer silk or internal thread, even can also form other pipe fitting such as elbow or threeway four-way.
During use, earlier locking nut 2 and opening shackle 3 are pierced on the external cylindrical surface of connected tube 1, end with connected tube 1 puts seal ring 5 again, thereafter, insert to connect in the endoporus of column jecket 4 bottom land together to " U " shape groove 6, then, snap ring 3 is allocated to the upper end-hole that is connected column jecket 4 downwards with nut 2, screw nut 2, at this moment opening shackle 3 shrinks and the connected tube 1 of holding with a firm grip under the thrust of nut 2 and the upper end-hole extruding that is connected column jecket 4, drives it simultaneously and moves down, the port inner wall of connected tube 1 is pressed on the circular cone inner cylinder 7 of groove 6 on the one hand, forms the sealing of first road; On the other hand, the end face of connected tube 1 is pressed on the inner ring bottom surface of the seal ring 5 that is loaded on groove 6 bottom surfaces, forms the sealing of second road; Again on the one hand, the expansive force that conical surface 7 produces makes connected tube 1 also produce expansion, and its outer cylinder just is pressed on the inwall of seal ring 5, forms three seals.Like this, just formed very good being tightly connected.
The utility model both can be used for the connection of aluminium-plastic composite pipe, also can be used for overall plastic pipe and engineering plastics pipe, also can be used for comprising being tightly connected of other water pipes of steel pipe.
