Abstract
The invention discloses a pipeline connection flange which comprises a flange and a joint which is mounted on the flange and used for being connected with a pipeline, wherein a mounting hole used for being connected with the pipeline is formed in the joint; sealing gasket is arranged on end surface of the flange; a sealing ring groove is formed in end surface of the joint, and a first sealing ring is mounted in the sealing ring groove; a second sealing ring is arranged in at least part of position of the side wall of the mounting hole; and the first sealing ring is E-shaped. According to the pipeline connection flange, the sealing gasket and a reinforced rib are arranged on the flange, so that the compression resistance of the flange is effectively increased, and the flange is not prone to damage in a use process; and the first sealing ring and the second sealing ring are arranged, the first sealing ring is E-shaped, at least two annular bulges are arranged on the second sealing ring, and accordingly, the sealing effect of the flange is better.
Description
Technical field
The present invention relates to pipeline sealing device field, relate in particular to a kind of pipeline connecting flange.
Background technique
Flange is again flange plate, is connected, or for by the part being connected between pipe and valve, is connected in the end of pipe fitting between pipe and pipe.On flange, have the bolt hole being fixed for bolt, bolt closely connects two flanges.Between two flanges that are installed together, with liner, seal.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, take brake tube for railway vehicle as example, and flange seal is poor, especially the closure gasket groove of seal ring consists 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.
Summary of the invention
The object of the invention 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 present invention by the following technical solutions:
A 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.
Beneficial effect of the present invention is: the present invention is provided with sealing gasket and stiffening rib on flange, has effectively increased the compression resistance of flange, makes flange in use be difficult for being damaged.
The present invention 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 present invention is three integral sealing annular grooves, can create whole sealed environment for the first seal ring, for flange provides favourable air-proof condition, makes sealability more reliable.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the pipeline connecting flange of specific embodiment of the invention 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
Below in conjunction with accompanying drawing and by embodiment, further illustrate technological scheme of the present invention.
As shown in Figure 1, be a kind of pipeline connecting flange that the present invention 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 preferred embodiment a kind of, 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 present invention 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 present invention 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 present invention is three integral sealing annular grooves, can create whole sealed environment for the first seal ring 3, for flange 1 provides favourable air-proof condition, makes sealability more reliable.
Know-why of the present invention has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present invention, and can not be interpreted as by any way limiting the scope of the invention.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present invention, within these modes all will fall into protection scope of the present invention.
