Abstract
The invention relates to a connector of tube, which is an improvement on the connecting device of mine tube, called as flange of mine tube, wherein the invention is characterized in that: the flange is annular; the annular wall of flange is uniformly distributed with at least two connecting holes; the tube wall between the connecting holes has concave groove. The invention has simple structure, saved material, and light weight; when the flange support of connected mine tube has hole, the flange can be light more. The invention can improve the producing safety and reduce the producing cost.
Description
Technical field
The invention belongs to the connection set of tubing, be to pipe joint technological improvement, it is called a kind of flange that connects mining pipe.
Background technique
In the prior art, on the mining pipe flange connecting annular wall, except attachment hole, other parts of flange wall are all entity, owing to after mining effective flange connects, in use will bear the weight of conveying liquid and the weight of pipe itself, and the strength of negative pressure or malleation, make pipe and flange easy deformation, cause damage and danger.Flange holder on the pipe two ends is too thick, and the flange between two pipes will bear very big pulling force when connecting, and this pulling force increases along with the thickness of flange holder, often adopts the thickness of thickening flange to solve, and causes waste serious.So the raw-material consumption of how to fall, strengthening bearing of flange upright is scientific worker's open question now of concentrating on studies.
Summary of the invention
The purpose of the present invention's design provides a kind of flange that connects mining pipe.Have Baltimore groove on the tube wall between the attachment hole of designed flange, according to the principle of I-steel, the Baltimore groove of being opened does not only influence the use brute force of flange, and use brute force that can also reinforcing flange, and make the reduced thickness of flange wall, saved raw material, reduced cost.Its technological scheme is:
To achieve these goals, the present invention can adopt following measure to realize, the mining pipe flange of described a kind of connection is characterized in that flange ringwise, the even attachment hole that distributes more than two and two has Baltimore groove on the tube wall between the attachment hole on the annular wall of flange.
For to achieve these goals, the present invention also can adopt following measure to realize, described a kind of flange that connects mining pipe, the shape that it is characterized in that the notch of the Baltimore groove between the flange attachment hole can be a kind of in irregularly shaped of circle, square, oval, crescent shape, rectangle, fan-shaped, long strip etc. and other, also can severally mix simultaneously and use.
Realize above-mentioned purpose, the present invention can adopt following measure to realize, the mining pipe flange of described a kind of connection is characterized in that between the flange attachment hole, on the end face of flange one and more than one Baltimore groove is arranged.
To achieve these goals, the present invention also can adopt following measure to realize, described a kind of flange that connects mining pipe, the shape that it is characterized in that the notch of the Baltimore groove between the flange attachment hole can be a kind of in irregularly shaped of circle, square, oval, crescent shape, rectangle, fan-shaped, long strip etc. and other.
To achieve these goals, the present invention also can adopt following measure to realize, described a kind of flange that connects mining pipe, it is characterized in that between the flange attachment hole, two end faces of flange have one and more than one Baltimore groove respectively, and the shape of notch can be a kind of in irregularly shaped of circle, square, oval, crescent shape, rectangle, fan-shaped, long strip etc. and other.
To achieve these goals, the present invention also can adopt following in order to realize, described a kind of flange that connects ore deposit _ usefulness pipe, there is Baltimore groove the inboard that it is characterized in that connecting tube, and the shape of notch can be a kind of in irregularly shaped of circle, square, oval, crescent shape, rectangle, fan-shaped, long strip etc. and other.
To achieve these goals, the present invention also can adopt following measure to realize, the mining flange of described a kind of connection is characterized in that the used material of flange body can be a kind of in the materials such as plastics, nylon and metal.
Description of drawings
Fig. 1 be the fluted direction of embodiments of the invention 1 described flange (1) the axial arrangement view.
Fig. 2 is the axial whole-cutaway view of embodiments of the invention 1 described flange.
The meaning of symbol is among the figure:
1 flange, 2 attachment holes, 3 Baltimore grooves, 4 Baltimore grooves
The present invention has following advantages:
The purpose of the present invention's design provides a kind of flange of connecting mine pipe, and its advantage is simple in structure Rationally, sturdy and durable, and save raw material, in the situation of same holding capacity, it is lighter and thin than the flange of entity, Can finish the work, when the flange support of the tubing that connects was porose, flange can be thinner lighter, makes flange Structural design more is tending towards rationally having solved the technical problem of flange distortion, has increased the safety coefficient of producing, joint Economize manpower and materials, greatly reduced production cost.
Specific embodiments
In order to be illustrated more clearly in the present invention, the present invention is done further explanation below in conjunction with embodiment and accompanying drawing:
