Description
Technical field
The utility model relates to pipeline sealing device field, relates in particular to a kind of pipeline connecting flange.
Background technique
Flange is again flange plate, for being connected between pipe and pipe, or for by the part being connected between pipe and valve, is connected in the end of pipe fitting.On flange, have the bolt hole being fixed for bolt, bolt closely connects two flanges.Between two flanges that are installed together, seal with liner.Flange is divided into the flange that is threaded, welded flange and cutting ferrule flange.
Flange arrangement for connection pipe fitting of the prior art, taking brake tube for railway vehicle as example, flange seal is poor, especially the closure gasket groove of seal ring is made up of jointly joint and flange body, causes Brake pipe poor sealing, and pressure air leaks, even lost efficacy, impact is normally used.
Therefore, a kind of pipeline connecting flange is needed in market badly, bad to solve in prior art flange seal flange seal poor and that cause, the problem even losing efficacy.
Model utility content
The purpose of this utility model is to propose a kind of pipeline connecting flange, bad to solve in prior art flange seal flange seal poor and that cause, the problem even losing efficacy.
For reaching this object, the utility model by the following technical solutions:
A kind of pipeline connecting flange, comprises flange and the joint for being connected with pipeline being installed on described flange, and described joint inside offers the mounting hole for being connected with pipeline, and the end face of described flange is provided with sealing gasket; The end face of described joint is provided with closure gasket groove, and the first seal ring is installed in described closure gasket groove; On the sidewall of described mounting hole, position is provided with the second seal ring at least partly; Described the first seal ring is E RunddichtringO.
Further, described the second seal ring is provided with annular protrusion.
Preferably, described the second seal ring and described mounting hole adopt the mode of bonding to be fixed together.
Further, between described flange and joint, be provided with stiffening rib.
Further, described closure gasket groove is three integral sealing annular grooves.
Preferably, described the second seal ring is provided with at least two circle annular protrusions.
Further, described flange is provided with bolt hole.
The beneficial effects of the utility model are: the utility model is provided with sealing gasket and stiffening rib on flange, have effectively increased the compression resistance of flange, make flange in use be difficult for being damaged.
The utility model is provided with the first seal ring and the second seal ring, and wherein the first seal ring is E RunddichtringO, is at least provided with two annular protrusions on the second seal ring, makes the sealing effect of flange better.
Closure gasket groove in the utility model is three integral sealing annular grooves, can be that the first seal ring is created overall sealed environment, for flange provides favourable air-proof condition, makes sealability more reliable.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the pipeline connecting flange of the utility model embodiment proposition.
In figure:
1, flange; 2, sealing gasket; 3, the first seal ring; 4, the second seal ring; 5, closure gasket groove; 6, stiffening rib; 7, joint.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
As shown in Figure 1, be a kind of pipeline connecting flange the utility model proposes, comprise flange 1 and the joint 7 for being connected with pipeline being installed on flange 1, joint 7 inside offer the mounting hole for being connected with pipeline.On flange 1, be also provided with bolt hole, bolt hole is for being fixed flange 1.
The end face of flange 1 is provided with sealing gasket 2, and the end face of joint 7 is provided with closure gasket groove 5, and the first seal ring 3 is installed in closure gasket groove 5.As following further mode of execution, closure gasket groove 5 is three integral sealing annular grooves.
Wherein, the first seal ring 3 is E RunddichtringO, and the seal ring of E type structure is than O RunddichtringO, and sealability is better.
On the sidewall of mounting hole, position is provided with the second seal ring 4, the second seal rings 4 and is provided with annular protrusion at least partly.The second seal ring 4 is provided with at least two circle annular protrusions, and in the present embodiment, the quantity of annular protrusion is three, and annular protrusion is in suitable quantitative range time, and the more sealing effects of quantity are better.As one preferred embodiment, the second seal ring 4 adopts the mode of bonding to be fixed together with mounting hole, can certainly adopt other the mode that both can be fixed, and is not limited in the mode of bonding.
In order to strengthen flange 1 in the present embodiment compression resistance in use, between flange 1 and joint 7, be provided with stiffening rib 6.
The utility model is provided with sealing gasket 2 and stiffening rib 6 on flange 1, has effectively increased the compression resistance of flange 1, makes flange 1 in use be difficult for being damaged.
The utility model is provided with the first seal ring 3 and the second seal ring 4, and wherein the first seal ring 3 is E RunddichtringO, is at least provided with two annular protrusions on the second seal ring 4, makes the sealing effect of flange 1 better.
Closure gasket groove 5 in the utility model is three integral sealing annular grooves, can be that the first seal ring 3 is created overall sealed environment, for flange 1 provides favourable air-proof condition, makes sealability more reliable.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, within these modes all will fall into protection domain of the present utility model.
