Abstract
The utility model relates to the technological improvement of a connecting device structure of mine pipes, which is named as a flange of mine pipes. The utility model is characterized in that the flange is annular, two and more than two connecting holes (2) are homogeneously distributed on the annular wall of the flange, the pipe wall between the connecting holes (2) is provided with a concave groove (3). The flange of the connecting mine pipes has the advantages of simple and reasonable structure, firmness and durability, and primary materials saving; the flange of connecting mine pipes is thinner than a physical flange for completing the task under the condition of similar bearing, when a flange support of the connected mine pipe has holes, the flange is thinner, the structural design of the flange is more reasonable, the technical problem of flange deformation can be solved, the safety factor of production can be increased, manpower and material resources can be saved, and the production cost can be reduced.
Description
Technical field
The utility model 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, the 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.
The model utility content
The purpose of the utility model 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 utility model can adopt following measure to realize, the mining pipe flange of described 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 utility model also can adopt following measure to realize, the flange of the mining pipe of described connection, 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 circle, square, oval, crescent shape, rectangle, fan-shaped, the long strip, uses simultaneously after also can be several mixed.
Realize above-mentioned purpose, the utility model can adopt following measure to realize, the mining pipe flange of described 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 utility model also can adopt following measure to realize, the flange of the mining pipe of described connection, 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 circle, square, oval, crescent shape, rectangle, fan-shaped, the long strip.
To achieve these goals, the utility model also can adopt following measure to realize, the flange of the mining pipe of described connection, 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 circle, square, oval, crescent shape, rectangle, fan-shaped, the long strip.
To achieve these goals, the utility model also can adopt following in order to realize, the flange of the mining pipe of described connection is characterized in that there is Baltimore groove the inboard of connecting tube, and the shape of notch can be a kind of in circle, square, oval, crescent shape, rectangle, fan-shaped, the long strip.
To achieve these goals, the utility model also can adopt following measure to realize, the mining flange of described connection is characterized in that the used material of flange body can be a kind of in plastics, nylon and the metallic material.
The utlity model has following advantage:
The purpose of the utility model design provides a kind of flange that connects mining pipe, and its advantage is simple and reasonable, and is sturdy and durable, and saving raw material, under the situation of same strength, it is than thin can the finishing the work of flange of entity, when the flange holder of the pipe that is connected is porose, flange can be thinner, make the structural design of flange more be tending towards rationally having solved the technical problem of flange distortion, increased the safety coefficient of producing, save manpower and materials, greatly reduced cost of production.
Description of drawings
Fig. 1 be the fluted direction of embodiment's 1 described flange (1) of the present utility model the axial arrangement view.
Fig. 2 is the axial whole-cutaway view of embodiment's 1 described flange of the present utility model.
The meaning of symbol is among the figure:
