Abstract
The utility model provides a sealing groove, the bottom surface of which is a conical surface. Because the bottom surface of the utility model is the conical surface, a sealing ring which is arranged in the sealing groove can be pressed towards the small end of the conical surface to lead the sealing ring to tightly press between connecters under the action of media. Then, sealing effect is enhanced. In addition, the sealing ring can automatically compensate and seal under the action of the media after the sealing ring is ground.
Description
(1) technical field:
The utility model relates to seal groove.
(2) background technique:
At present, the various mechanical connections that are used for the oil gas conveying need the seal groove of sealing part all rectangular, and the bottom surface of seal groove is cylndrical surface or plane, leakage phenomenon will occur when the pressure of working medium increases, and influence sealing effect.
(3) summary of the invention:
The utility model provides the seal groove of a kind of good sealing effect and energy automatic compensation sealing at the deficiencies in the prior art.
The solution that the utility model adopts is: the bottom surface of sealing groove is the conical surface.
The utility model is because its bottom surface is the conical surface, and the seal ring under the effect of medium in the groove can be pressed towards conical surface small end, and seal ring is pressed between the link, has strengthened sealing effect.And can automatic compensation sealing under the medium effect behind the ring wear.
(4) description of drawings:
Fig. 1 is the structural representation of the utility model radial seal groove.
Fig. 2 is the structural representation of the utility model end face seal groove.
Wherein: 1, seal groove, 2, the conical surface
(5) embodiment:
Embodiment:
Fig. 1 has provided the structural representation of the utility model radial seal groove, and the bottom surface of seal groove 1 is the conical surface 2, and width suitably strengthens, and has made things convenient for assembling.After passing through pressure medium, the working pressure of medium is pressed onto medium to produce on the left side of groove inner seal ring moving to the right, and the bottom land of seal groove diameter is more little more to the right, increase along with pressure, the radial pressure of seal ring also increases, thereby improved sealing effect, the wearing and tearing of energy automatic compensation sealing circle do not influence sealing effect.Fig. 2 has provided the structural representation of the utility model end face seal groove, the bottom surface of sealing groove also is the conical surface, after passing through pressure medium, the working pressure of medium radially is pressed onto on the groove inner seal ring medium, produces outside expansion, and the degree of depth of seal groove is outside more shallow more, along with the increase of pressure, the axial pressure of seal ring also increases, thereby has improved sealing effect, and the wearing and tearing of energy automatic compensation sealing circle, do not influence sealing effect.
Claims (1)
1. seal groove, it is characterized in that: the bottom surface of sealing groove is the conical surface.
