Abstract
The utility model discloses a ring flange for connecting an oil delivery pipe, which comprises a ring flange body provided with a through hole, wherein the ring flange body is provided with a fixing ring. The ring flange has a simple structure, good sealability and a high safety coefficient, and can meet the requirements of high-pressure components such as petroleum delivery pipelines and the like.
Description
Technical field
The utility model relates to a kind of flange plate, especially relates to a kind of transport pipe flange connecting dish that is used for.Belong to mechanical field.
Background technique
Flange is a kind of discoid part, and is the most common in pipework, and flange all is to use in pairs.In pipework, flange is mainly used in the connection of pipeline.At the pipeline that needs connect, various installation a slice flange plate, low pressure pipeline can use the wire connection flange, 4 kilograms of use welded flanges with upward pressure.Add sealing gasket between two flange plate, use bolton then.
Water pump and valve, when being connected with pipeline, the part of these equipment facilities; Also process corresponding flange shape; Be also referred to as flange and connect, every union piece that uses the bolt connection to seal simultaneously at periphery on two planes generally all is called " flange "; Like the connection of ventilation duct, this type part can be called " flange type part ".It is exactly two pipelines, pipe fitting or equipment that flange connects, and is fixed on separately on the flange plate earlier, between two flange plate, adds flange gasket, with bolton together, has accomplished connection.Pipe fitting that has and equipment have carried flange plate, also are to belong to flange to connect.It is the important Placement of pipeline construction that flange connects.Flange connects easy to use, can bear bigger pressure.In industrial pipeline, the use that flange connects very extensively.Within the family, pipe diameter is little, and is low pressure, cannot see flange and connects.If in a boiler room or production scene, be pipeline and the equipment that flange connects everywhere.Traditional flange arrangement is complicated, and at the fastening process poor sealing performance of flange, safety coefficient is low, can't satisfy the conveyance conduit of High Voltage such as petroleum pipeline.
The model utility content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned existing technology, and a kind of transport pipe flange connecting dish that is used for is provided, and said flange plate structure is simple, good seal performance, and safety coefficient is high, can satisfy the parts of High Voltage such as petroleum transportation pipeline.
The purpose of the utility model realizes through following technical proposals: be used for transport pipe flange connecting dish, comprise the flange plate body that is provided with through hole, said flange plate body is provided with retaining ring.
The medial axis of said retaining ring overlaps with the medial axis of flange plate body.
Said through hole is arranged on the center of flange plate body, and the size of through hole is consistent with the internal diameter size of retaining ring.
Said flange plate body is provided with some grooves one, and said groove one is evenly distributed on the flange plate body.
The quantity of said groove one is six.
Be provided with the penetration hole that runs through the flange plate body on the said groove one, the size of said penetration hole is less than the size of groove one, and the medial axis of penetration hole overlaps with the medial axis of groove one.
Said retaining ring is provided with some grooves two, and said groove two is evenly distributed on the retaining ring.
The quantity of said groove two is nine.
In sum, the beneficial effect of the utility model is: said flange plate structure is simple, good seal performance, and safety coefficient is high, can satisfy the parts of High Voltage such as petroleum transportation pipeline.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
Mark and corresponding component title in the accompanying drawing: 1-flange plate body; 2-retaining ring; 3-groove one; 4-penetration hole; 5-groove two; 6-through hole.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the mode of execution of the utility model is not limited only to this.
Embodiment:
Like Fig. 1, the transport pipe flange connecting dish that is used for shown in Figure 2, comprise the flange plate body 1 that is provided with through hole 6, said flange plate body 1 is provided with retaining ring 2.Oil is through in through hole 6 flow ipes, and the groove 25 that is provided with on the retaining ring 2 is connected with pipeline.
The medial axis of said retaining ring 2 overlaps with the medial axis of flange plate body 1.Kept being under pressure between retaining ring 2 and the flange plate body 1 evenly, can not cause sealing to go wrong.
Said through hole 6 is arranged on the center of flange plate body 1, and the size of through hole 6 is consistent with the internal diameter size of retaining ring 2.Keep consistent size, can effectively prevent tightness, be convenient to for the installation of pipeline provides simultaneously, practice thrift the cost that pipeline is made.
Said flange plate body 1 is provided with some grooves 1, and said groove 1 is evenly distributed on the flange plate body 1.Groove 1 is as an end fixing head of bolt, can reduce outstanding, visually more attractive in appearance with respect to flange body 1 of bolt head and nut through groove 1.
The quantity of said groove 1 is six.Through six grooves 1, can two flange body 1 firmly be fixed, six grooves 1 be evenly distributed on flange body 1 around.
Be provided with the penetration hole 4 that runs through flange plate body 1 on the said groove 1, the size of said penetration hole 4 is less than the size of groove 1, and the medial axis of penetration hole 4 overlaps with the medial axis of groove 1.The penetration hole 4 of two flange plate bodies 1 is aligned with each other, and bolt passes penetration hole 4, carries out fixed by nut in the position of groove 1.Through six penetration holes 4, can the connection between the flange plate body 1 is tightr, after oil transport pipeline work, can be owing to pressure causes the situation that occurs leaking.
Said retaining ring 2 is provided with some grooves 25, and said groove 25 is evenly distributed on the retaining ring 2.Can pipeline be fixed through groove 25, make between flange plate body 1 and the pipeline combine tightr.
The quantity of said groove 25 is nine.Adopt nine grooves 25, can pipeline firmly be fixed on the flange plate body 1, situation not in place can not occur sealing.
Take aforesaid way, just can realize the utility model preferably.
