Abstract
An abrasion proof earthenware conduit, includes a pipe, a connection-peg and an interface, wherein the connection-peg and the interface are respectively arranged on the two ends of the pipe and form the integrated structure. At least a groove for circling the tube wall is arranged on the outer pipe wall of the connection-peg, and a sealing ring is arranged in the groove. The inside diameter of the interface is larger than the outside diameter of the connection-peg. When in connection, the connection-peg of the pipe is inserted into the interface of the other pipe. The invention has simple operation, convenient and fast connection, good sealing effect of the pipe interface, simple structure, easy production and low cost.
Description
Technical field
The present invention relates to a kind of abrasion-proof earthenware duct, a kind of specifically abrasion-proof earthenware duct that is provided with seal connector in pipe ends.
Technical background
At present, in the cement industry, tertiary-air pipe, high temperature airduct, powder delivering pipe etc. are used metallic conduit mostly, weight is big, price is high, abrasion-proof earthenware duct can overcome these shortcomings, but, because earthenware duct can't weld as metal, tube wall is thinner in addition, and external connected elements such as thread connecting mode or flange are all inapplicable, pipeline is difficult for connecting, and the earthenware duct pipe surface is coarse, and the connection interface sealing effect is bad, and these problems have hindered it and applied, therefore, press for a kind of abrasion-proof earthenware duct easy, good airproof performance that connects is provided.
Summary of the invention
The objective of the invention is deficiency, provide a kind of and have good seal performance, can implement fixedly connected abrasion-proof earthenware duct in pipe ends for solving the problems of the technologies described above.
The present invention is the deficiency that solves the problems of the technologies described above, the technological scheme that is adopted is: a kind of abrasion-proof earthenware duct, comprise pipeline, connection-peg and birdsmouth, connection-peg and birdsmouth are located at the two ends of pipeline respectively, be structure as a whole with pipeline, the outer tube wall of connection-peg is provided with the groove around tube wall one circle of at least one, is provided with seal ring in the groove.
The present invention also can adopt following technological scheme: a kind of abrasion-proof earthenware duct, comprise pipeline, connection-peg and birdsmouth, connection-peg and birdsmouth are located at the two ends of pipeline respectively, be structure as a whole with pipeline, the outer tube wall of connection-peg is provided with two grooves around tube wall one circle, is provided with seal ring in the groove.
The present invention, the internal diameter of described birdsmouth is greater than the external diameter of connection-peg.
The present invention, described seal ring is a high-temperature resistant seal ring, its cross section is trapezoidal, rectangle or ellipse.
The present invention, during connection the connection-peg of a pipeline is inserted the birdsmouth of another root pipeline, seal ring is clipped between connection-peg and the birdsmouth, not only play the effect of sealing, also avoided pipeline directly to contact the impact failure of generation, in the seam of connection-peg and birdsmouth, inserted materials such as tackiness agent again and make better tightness.
The invention has the beneficial effects as follows:
1, simple to operate, easy to connect, quick.
2, pipe joint good sealing effect.
3, two pipe joint places have seal ring to make liner, and tube wall is directly contact not, has avoided impact failure.
4, simple in structure, be easy to produce, cost is low.
5, pipeline Wear-resistant, high-temperature resistant, long service life.

Embodiment
As shown in Figure 1, abrasion-proof earthenware duct, comprise pipeline 3, connection-peg 1 and birdsmouth 2, connection-peg 1 and birdsmouth 2 are located at the two ends of pipeline 3 respectively, be structure as a whole with pipeline 3, the internal diameter of birdsmouth 2 is greater than the external diameter of connection-peg 1, and the outer tube wall of connection-peg 1 is provided with four grooves 4 around tube wall one circle, be provided with seal ring 5 in the groove 4, the cross section of seal ring 5 is trapezoidal.
As shown in Figure 1, abrasion-proof earthenware duct, comprise pipeline 3, connection-peg 1 and birdsmouth 2, connection-peg 1 and birdsmouth 2 are located at the two ends of pipeline 3 respectively, be structure as a whole with pipeline 3, the internal diameter of birdsmouth 2 is greater than the external diameter of connection-peg 1, and the outer tube wall of connection-peg 1 is provided with four grooves 4 around tube wall one circle, be provided with seal ring 5 in the groove 4, the cross section of seal ring 5 also can be rectangle.
As shown in Figure 3, the connection-peg 1 of pipeline inserted the birdsmouth 2 of another pipeline when two pipelines connected, and seal ring 5 is clipped between connection-peg 1 and the birdsmouth 2, makes the pipe joint sealing, and tube wall is directly contact not, and has avoided impact failure.In addition, better in order to make sealing effect, need be at the filling adhesive in the slit that is connected of connection-peg 1 and birdsmouth 2.
