Abstract
The utility model discloses a centrifugal nodular cast iron pipe which comprises a bellmouth and a faucet, wherein the annular sealing surface of the bellmouth is provided with the annular sealing groove of the bellmouth, the external cylindrical surface of the inserting section of the faucet is provided with a faucet sealing groove, and the position of the faucet sealing groove on the external cylindrical surface of the inserting section of the faucet of one nodular cast iron pipe corresponds to the position of the annular sealing groove of the bellmouth of another nodular cast iron pipe. The utility model is a novel centrifugal nodular cast iron pipe which adds the sealing groove on the sealing surface of a joint and can prolong the service life of air and water feed pipelines.
Description
Technical field
The utility model relates to a kind of ductile iron pipe.
Background technique
At present, the seal form of ductile iron pipe has varied, and its sealing surface all is the anchor ring of an opposed flattened, relies on the tension force of O-ring seal to realize sealing.Along with the O-ring seal prolongation of service time, O-ring seal is aging gradually, thereby loses due elasticity because of tired, and more and more littler to the static pressure of Cast tube joint sealing surface, sealing effect descends gradually, finally loses sealing.Why air feed, water supply line all have service life, and reason just is this.Therefore, designing a kind of new interface ductile iron pipe that can prolong the service life of air feed, water supply line, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of new interface ductile iron pipe that can prolong the service life of air feed, water supply line.
The technical scheme in the invention for solving the technical problem is:
A kind of centrifugal ductile cast iron pipes, the bellmouth and the socket that comprise it, the annular sealing surface of bellmouth is provided with bellmouth ring packing groove, the outer cylinder of the insertion section of socket is provided with the spigot seal groove, and the position of the spigot seal groove on the socket insertion section outer cylinder of a ductile iron pipe is corresponding with the position of the bellmouth ring packing groove of another ductile iron pipe.
The technical scheme in the invention for solving the technical problem can also be:
The utility model is provided with multiple tracks bellmouth ring packing groove along its length on the annular sealing surface of bellmouth, be provided with multiple tracks spigot seal groove along its length on the outer cylinder of the insertion section of socket.
The sectional shape of spigot seal groove described in the utility model is triangle, rectangle or trapezoidal.
The sectional shape of bellmouth ring packing groove described in the utility model is triangle, rectangle or trapezoidal.
Compared with prior art, the utility model improves the sealing effect of cast tube by add sealed groove on the sealing surface of interface, thereby has realized prolonging air feed, the water supply line purpose of service life.
