Abstract
The utility model relates to a pipe fitting which comprises a tubular body; one end of the tubular body is provided with a thread, and the other end of the tubular body is provided with a circular groove for fixing a seal ring; and the cross section of the circular groove is in a 'angle' shape. According to the pipe fitting, the use is convenient, the sealing effect is good, and the automatic separation of the seal ring and the pipe fitting is effectively prevented.
Description
Technical field
The utility model relates to a kind of connection set, especially a kind of pipe joint that is installed on the pump housing.
Background technique
On the pump housing, be positioned at cylinder body one side pipe joint is installed, be used for connected pipes, output and the input of guiding fluid.Usually, pipe joint is annular tube shaped body, and it is threaded with cylinder body, is connected by flange with oil pipe.In order to prevent the leakage of oil at pipe joint place, all seal ring can be installed at pipe joint and cylinder body joint, seal.So, all be provided with the draw-in groove of fixed seal ring on the pipe joint, on the existing pipe joint, the cross section of draw-in groove is rectangle, after seal ring is installed in the draw-in groove, its position is fixed, and in order to increase the working life of seal ring, prolongs the replacing time of seal ring, usually after seal ring is installed in the draw-in groove, seal ring need to be arranged to exceed a draw-in groove part, like this when the design and installation seal ring, also need according to calculating such as the degree of depth of draw-in groove and width, use very trouble, after being installed to pipe joint very large error is arranged, cause leakage, sealing effect is poor.And when the dismounting pipe joint, seal ring is easy to break away from pipe joint, also needs to reinstall, and has so not only wasted the time, and has caused easily the distortion of seal ring.
The model utility content
The utility model purpose is that a kind of easy to use, good sealing effect is provided in order to overcome the deficiencies in the prior art, prevents the pipe joint that seal ring breaks away from.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pipe joint, packing tubular body; One end of described tubular body is provided with screw thread; The other end of described tubular body has the circular groove of fixed seal ring; The cross section of described circular groove is " ∠ " shape.
Preferably, described circular groove is two.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of pipe joint of the utility model scheme, its " ∠ " shape circular groove by having at tubular body, so that after seal ring is installed in the circular groove, its position be have flexible, can automatically adjust its position according to the pressure of cylinder body and pipe joint, do not need to adjust seal ring according to circular groove, the time easy to use, strengthened sealing yet; And the design of " ∠ " shape circular groove can effectively prevent pipe joint when dismounting, and the disengaging of seal ring has guaranteed the sealing effect of seal ring, the working life of having improved seal ring.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the perspective view of pipe joint of the present utility model;
Accompanying drawing 2 is the plan view of pipe joint of the present utility model;
Wherein: 1, tubular body; 2, circular groove.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
Claims (2)
