Abstract

The utility model relates to a connection pipe which comprises a cylindrical pipe, a flanging ring connected at one end of the cylindrical pipe, a through hole penetrating through the cylindrical pipe and the flanging ring, a connection face arranged at the end, not connected with the cylindrical pipe, of the flanging ring and fixation holes formed in the flanging ring. A gasket which is concentric with the flanging ring is arranged on the connection face. A plastic gasket is further arranged on the connection face. The position, corresponding to the connection face, of the plastic gasket is provided with a corresponding hole. The inner circumference of the plastic gasket is larger than the outer circumference of the gasket. The position, where the through hole exists, of the flanging ring is of an outwards expanding slant structure from the inner end of the through hole to the outer end of the flanging ring and in the shape of a funnel. The thickness of the gasket ranges from 0.6mm to 3mm and the thickness of the plastic gasket ranges from 1mm to 5mm. The number of the fixation holes ranges from 4 to 6. The connection pipe is made of 45 steel and formed in a press-casting mode. The connection pipe can prevent a pipe body from being easily deformed and fractured under a high pressure state and is convenient to machine and low in cost.

Description

A kind of connecting tube
Technical field
The utility model relates to the mechanical pipe field, particularly relates to a kind of connecting tube.
Background technique
connecting tube application in mechanical pipe connects is quite extensive, the flange connecting tube is by tubing one end or the typing of two ends heating flange through special mechanical equipment, but existing flange connecting pipe structure is too simple, one end of flange is all a smooth plane usually, like this, when with other pipeline part, being connected, what joint sealed is not very tight, people added Upper gasket between connection mouth afterwards, can make sealing of interface fine, but the time one is long, part can shake in the process of mechanical motion, between part, will produce the strength of punching press, make the pad distortion even damaged, thereby cause the leakage of liquid.
The model utility content
The technical problem that the utility model mainly solves is to provide a kind of convenient for production, the connecting tube that can effectively protect pad not to be damaged.
For solving the problems of the technologies described above, the main technical content that the utility model adopts is as follows: a kind of connecting tube, comprise the cylinder pipe, be connected in the flange circle of cylinder Guan Yiduan, the through hole that runs through cylinder pipe and flange circle, an end that is not connected with the cylinder pipe at the flange circle be provided with junction surface and be arranged on the fixed hole on the flange circle, it is characterized in that; On described junction surface, be provided with a packing ring with described flange circle phase concentric, on described junction surface, also be provided with plastic spacer, described plastic spacer is provided with corresponding hole in the corresponding position of described junction surface, the thickness of described plastic spacer is greater than the thickness of described packing ring, the inner circumference of described plastic spacer is greater than the excircle of described packing ring, described through hole adopts in the outer end of position from the through hole inner end to the flange circle of flange circle the leaning structure that extends out, and is " funnel-like ".
Aforesaid a kind of connecting tube is characterized in that: the thickness of described packing ring is 0.6mm-3mm, and the thickness of described plastic spacer is 1 mm-5mm.
Aforesaid a kind of connecting tube is characterized in that: described fixed hole is 4-6.
Aforesaid a kind of connecting tube is characterized in that: the material of described connecting tube adopts 45 steel, and passes through casting.
By technique scheme, the utility model has following advantages at least: the utility model arranges packing ring and can effectively protect pad not to be damaged on junction surface; Through hole adopts the leaning structure that extends out can allow liquid circulate faster in the outer end of position from the through hole inner end to the flange circle of flange circle, reduces the pressure of joint; The thickness of packing ring is 0.6mm-3mm, and the thickness of plastic spacer is 1 mm-5mm, can not only allow like this plastic spacer play the effect of sealing, also can protect plastic spacer not to be damaged by packing ring; Fixed hole adopts 4-6, not only good fixing effect, and convenient disassembly; The material of the utility model connecting tube adopts 45 steel in addition, and easy to process, cost is low; By casting, can prevent body easily deformation and fracture under high pressure conditions.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of connecting tube of the utility model.
Fig. 2 is the plastic spacer scheme of installation of a kind of connecting tube of the utility model.
In figure, the mark of each parts is as follows: 1, cylinder pipe, 2, the flange circle, 3, packing ring, 4, fixed hole, 5, through hole, 6, junction surface.
Embodiment
For further setting forth the utility model, be to reach technological means and the effect that predetermined model utility purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, its embodiment, structure, feature and effect thereof to according to the utility model proposes, be described in detail as follows.
Refer to Fig. 1, a kind of connecting tube of the utility model, comprise cylinder pipe 1, be connected in the flange circle 2 of cylinder Guan Yiduan, the through hole 5 that runs through this cylinder pipe 1 and flange circle 2, an end that is not connected with cylinder pipe 1 at flange circle 2 be provided with junction surface 6 and be arranged on the fixed hole 4 on flange circle 2, it is characterized in that; On described junction surface 6, be provided with a packing ring 3 with described flange circle 2 phase concentrics, on described junction surface 6, also be provided with plastic spacer 7, described plastic spacer 7 is provided with corresponding hole in the corresponding position of described junction surface 6, the thickness of described plastic spacer 7 is greater than the thickness of described packing ring 3, the inner circumference of described plastic spacer 7 is greater than the excircle of described packing ring 3, described through hole 5 adopts in the outer end of position from through hole 5 inner ends to flange circle 2 of flange circle 2 leaning structure that extends out, and is " funnel-like ".The thickness of described packing ring 3 is 0.6mm-3mm, and the thickness of described plastic spacer 7 is 1 mm-5mm; Described fixed hole 4 is 4-6; The material of described connecting tube adopts 45 steel, and passes through casting.
Refer to Fig. 2; the utility model is placed on plastic spacer 7 between junction surface 6 and the parts that will be connected in use; with screw, by fixed hole 4, by between them, firmly tighten; being screwed to packing ring 3 touches as the optimum state with the face of connected element; can not only pass through plastic spacer 7 good seal jointings like this, and the packing ring 3 that protrudes from junction surface 6 also can effectively be protected plastic spacer 7.
