Abstract
The utility model relates to a loose flange which comprises a pipeline connecting body. A through hole for a pipeline to be inserted is arranged in the pipeline connecting body. The side wall of the pipeline connecting body extends outward to form a ring-shaped flange. A plurality of location holes are arranged in the ring-shaped flange. One end face of the ring-shaped flange is arranged in a way of being aligned to the end face of the pipeline connecting body. The side wall of the pipeline connecting body and the other end face of the ring-shaped flange are connected through an arc transition face which is arranged in a way of bending to the inner side. Due to the technical scheme, the loose flange can avoid excessive part stress between the ring-shaped flange and the side wall of the pipeline connecting body and effectively prevents the broken phenomenon from occurring.
Description
Technical field
The utility model relates to a kind of lap joint flange.
Background technique
Lap joint flange relies on its volume little, closely reliable, and operation and maintenance is convenient, and withstand voltage, corrosion resistant performance has been widely used in the fields such as oil, chemical industry, food, dairy products, pharmacy, machine-building, sewage treatment, municipal water supply pipeline, fire protection pipeline.
Existing a kind of lap joint flange, include the pipeline connecting body, described pipeline connecting body is provided with the through hole that inserts for pipeline, described pipeline connecting body sidewall is outward extended with annular flange flange, described annular flange flange is provided with some positioning holes, the setting of aliging with an end face of pipeline connecting body of a wherein end face of described annular flange flange, angle of attachment between the other end of annular flange flange and the pipeline connecting body sidewall is the right angle, the general paired use of lap joint flange, when connecting, two pipelines that only needs need to be connected insert in the through hole of lap joint flange, and the through hole holding down bolt gets final product the lap joint flange connection of two pipelines again.
But, the lap joint flange of this structure, localized stress is larger between annular flange flange and pipeline connecting body sidewall, easily produces phenomenon of rupture, and then causes unnecessary trouble.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of lap joint flange, can avoid between annular flange flange and the pipeline connecting body sidewall localized stress excessive, thereby can prevent effectively that its phenomenon of rupture from occuring.
The technical solution of the utility model: a kind of lap joint flange, include the pipeline connecting body, described pipeline connecting body is provided with the through hole that inserts for pipeline, described pipeline connecting body sidewall is outward extended with annular flange flange, described annular flange flange is provided with some positioning holes, the setting of aliging with the end face of pipeline connecting body of a wherein end face of described annular flange flange, it is characterized in that: be connected through arc-shaped transitional surface between the other end of described pipeline connecting body sidewall and annular flange flange, described arc-shaped transitional surface is crooked the setting to the inside.
Adopt technique scheme, can avoid between annular flange flange and the pipeline connecting body sidewall localized stress excessive by the arc-shaped transitional surface that arranges, thereby can effectively prevent its phenomenon of rupture generation.
Further setting of the present utility model: the end face that annular flange flange is alignd with the pipeline connecting body is connecting end surface, and the through hole that is positioned at annular flange flange connecting end surface one side expands outwardly setting.
Adopt above-mentioned further setting, the through hole that is positioned at annular flange flange connecting end surface one side expands outwardly setting, when pipeline docks, can between pipeline joint and through-hole side wall Sealing be set like this, thereby can prevent that medium from producing leakage at the pipeline joint.
Again further setting of the present utility model: the both sides end face of described pipeline connecting body circumferentially is equipped with the buffering chamfering, and described buffering chamfering is 45 °.
Adopt above-mentioned more further setting, 45 ° of buffering chamferings can avoid the both sides end face of pipeline connecting body circumferentially to stab the staff.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
As shown in Figure 1, a kind of lap joint flange, include pipeline connecting body 1, described pipeline connecting body 1 is provided with the through hole 11 that inserts for pipeline, described pipeline connecting body 1 sidewall is outward extended with annular flange flange 2, pipeline connecting body 1, annular flange flange 2 is Carbon Steel Plate and makes, described annular flange flange 2 is provided with some positioning holes 21, the setting of aliging with an end face 12 of pipeline connecting body 1 of a wherein end face of described annular flange flange 2, the end face that annular flange flange 2 is alignd with pipeline connecting body 1 is connecting end surface 22, the other end 13 of pipeline connecting body 1 is positioned at 23 outsides, other end of annular flange flange 2, be connected through arc-shaped transitional surface 3 between the other end 23 of described pipeline connecting body 1 sidewall and annular flange flange 2, described arc-shaped transitional surface 3 is crooked the setting to the inside.
As shown in Figure 1, in the utility model specific embodiment, the through hole 111 that is positioned at annular flange flange 2 connecting end surfaces 22 1 sides expands outwardly setting, is horn-like so that be positioned at the through hole 111 of annular flange flange 2 connecting end surfaces 22 1 sides.
As shown in Figure 1, in the utility model specific embodiment, the both sides end face of described pipeline connecting body 1 circumferentially is equipped with buffering chamfering 14, and described buffering chamfering 14 is 45 °.
