Description

A kind of Pipe installing flange that sealing effect is good
Technical field
The utility model relates to Pipe installing flange, the good Pipe installing flange of specially a kind of sealing effect.
Background technique
Pipeline is connected into pipe, pipe connector and valve etc. for conveying gas, liquid or with solid particle Fluid device.Pipeline is multi-field because of its own unique feature, extensive use and conglomerate.Having many uses for pipeline is general, It is used primarily in water supply, draining, heat supply, gives gas, long distance delivery oil and natural gas, agricultural irrigation, hydraulic engineering and various In commercial plant, and pipeline needs to use pipe flange during installation, flange, is called flange flange disk or flange.Flange is axis The part interconnected between axis, for the connection between pipe end;Also have with the flange on equipment is imported and exported, be used for two Connection between equipment, such as speed reducer flange.Flanged joint or bump joint refer to mutual by flange, gasket and bolt three It is connected to the releasable connection of one group of combined sealing structure.Pipe flange means in plumbing installation with effective flange, used in setting The standby inlet and outlet flange for above meaning equipment.Perforation on flange, bolt are close to two flanges.With liner sealing between flange.Flange Divide and is threadedly coupled flange, welded flange and clip flange.Flange all uses in pairs, and a connection can be used in low pressure pipeline Orchid, the use welded flange of four kilograms of pressure above.Gasket is added between two panels ring flange, then uses bolt fastening.It is different The flange thickness of pressure is different, and the bolt that they are used is also different.Water pump and valve, when connecting with pipeline, these equipment are set Corresponding flange shape, also referred to as flanged joint is also made in standby part.It is all to be bolted in two planar perimeter uses Closed union piece, generally referred to as flange simultaneously, such as the connection of ventilation shaft, this kind of parts are properly termed as flange type zero Part.But this connection is the part of an equipment, such as the connection of flange and water pump, just it is bad water pump flange type zero Part.More small-sized such as valve, can be " flange type part.
But sealing effect is bad during installation for existing flange, is easy to cause leak or gas leakage.For this purpose, we mention The good Pipe installing flange of a kind of sealing effect out.
Utility model content
The purpose of this utility model is to provide a kind of good Pipe installing flanges of sealing effect, to solve above-mentioned background The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of Pipe installing that sealing effect is good use Flange, including flange installation plate body and flange install cylinder, and the flange mounting cylinder body is located at flange installation plate body side and consolidates Fixed connection, the flange installation plate body upper end face are provided with salient point, and the salient point upper end face is provided with No. two grooves, described No. two inside grooves are provided with No. two sealing rings, and No.1 groove, the No.1 inside grooves setting are provided on the outside of the salient point There is No.1 sealing ring, is provided with pilot hole on the outside of the No.1 groove.
Preferably, the external side surface of flange mounting cylinder is provided with No. three grooves, and No. three inside grooves are provided with No. three sealing rings.
Preferably, the pilot hole and No. two groove particular numbers are provided with several groups.
Preferably, the bumps inside is provided with through-hole.
Preferably, flange installation body end surface two sides are arranged to skewed.
Compared with prior art, the utility model has the beneficial effects that
1. the utility model is provided with No. two grooves and No. two sealing rings by being provided with salient point, and in bump surface, When pipe flange carries out abutting joint, so that No. two sealing rings in salient point in two groups of flanges carry out mutually extruding sealing, So that the sealing effect of salient point junction is more preferable, to improve the integral sealing effect of Pipe installing flange.
2. the utility model is by being provided with No.1 sealing ring and No. three sealing rings, No.1 sealing ring can be very good so that Two groups of flanges installation plate bodys are even closer when being installed, and greatly improve the sealing performance of flange, and No. three sealing rings It can be very good so that flange is in connecting pipe, so that flange installation cylinder tightly touch pipeline, be effectively increased pipeline With the sealing performance of flange connections.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram;
Fig. 2 is the utility model side structure schematic view.
In figure: 1 flange install plate body, 2 pilot holes, 3 No.1 sealing rings, 4 No.1 grooves, 5 through-holes, 6 salient points, 7 No. two it is recessed Slot, 8 No. two sealing rings, 9 No. three sealing rings, 10 No. three grooves, 11 flanges install cylinder.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of Pipe installing usage that sealing effect is good Orchid, including flange installation plate body 1 and flange install cylinder 11, and the flange installation cylinder 11 is located at flange installation 1 side of plate body And be fixedly connected, flange installation 1 upper end face of plate body is provided with salient point 6,6 upper end face of salient point be provided with No. two it is recessed Slot 7, No. two grooves 7 are internally provided with No. two sealing rings 8, No.1 groove 4, the No.1 are provided on the outside of the salient point 6 Groove 4 is internally provided with No.1 sealing ring 3, is provided with pilot hole 2 on the outside of the No.1 groove 4.
Further, flange installation 11 outer surface of cylinder is provided with No. three grooves 10, in No. three grooves 10 Portion is provided with No. three sealing rings 9, and No. three sealing rings 9 can be very good so that flange is in connecting pipe, so that flange mounting cylinder Body 11 tightly touch pipeline, is effectively increased the sealing performance of pipeline and flange connections.
Further, the pilot hole 2 and No. two 7 particular numbers of groove are provided with several groups, so that two groups of flanges are being pacified It is even closer when dress, and No. two grooves 7 of several groups make the sealing effect in docking of salient point 6 more preferable.
