Abstract
The utility model discloses a sealing ring for a pipe joint. The sealing ring comprises a sealing ring body, wherein a cross section of the sealing ring body is basically circular; and the sealing ring body is provided with an extending part extending outwards, wherein the extending part forms a circle of sealing plane on an inner circle of the sealing ring. The sealing ring disclosed by the utility model is deformed, so that the sealing ring has a deformed shape in the prior art at the beginning; and after the sealing ring is clamped and pressed, the sealing area of the clamped and pressed sealing surface is greater and the sealing performance is better.
Description
Technical field
The utility model relates to a kind of pipe joint and uses seal ring.
Background technique
As shown in Figure 1, an end of pipe joint generally has a receiving groove that is used to hold seal ring, and the seal ring plug is in receiving groove.In the prior art, the sealing circle all is an O-ring seals generally, and its cross section is rounded.When installing, as shown in Figure 2, card is pressed back O-ring seals distortion, thereby reaches the effect of sealing.The shortcoming of its existence is: the sealability of O-ring seals is still waiting to improve.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing pipe joint with seal ring, the utility model provides a kind of pipe joint of better tightness to use seal ring.
The technological scheme that the utility model solves its technical problem is: a kind of pipe joint is used seal ring, comprises the sealing circle body, and the cross section of described sealing circle body is the basis with the circle, has outward extending extension part.
Further, described extension part round-formed circle sealing plane in said seal ring.
The utility model in use, and is the same with seal ring with existing pipe joint, and it is filled in the seal ring receiving groove of pipe joint, realizes seal action after card is pressed.
The beneficial effect of the utility model is: seal ring has been done distortion, makes that seal ring promptly has deformed shape of the prior art at the beginning, and the sealing area of sealing surface is bigger after card is pressed, and sealability is better.
Description of drawings
Fig. 1 is the assembling schematic representation of existing pipe joint with seal ring.
Fig. 2 is the user mode figure of existing pipe joint with seal ring.
Fig. 3 is the assembling schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 3, a kind of pipe joint is used seal ring, comprises sealing circle body 1, and the cross section of described sealing circle body is the basis with the circle, has outward extending extension part 2.Extension part 2 described in the present embodiment is a round-formed circle sealing plane in said seal ring, and promptly the interior circle of seal ring is a plane.
The seal ring of the utility model has been done distortion, makes that seal ring promptly has deformed shape of the prior art at the beginning, and the sealing area of sealing surface is bigger after card is pressed, and sealability is better.
Claims (2)
1. a pipe joint is used seal ring, comprises the sealing circle body, it is characterized in that: the cross section of described sealing circle body is the basis with the circle, has outward extending extension part.
2. pipe joint as claimed in claim 1 is used seal ring, it is characterized in that: described extension part is a round-formed circle sealing plane in said seal ring.
