Description

Clar pipe

Technical Field

The utility model relates to a carat pipe.

Background

When the existing Krah pipe is connected, most of the existing Krah pipes are welded, but live working is forbidden in rainy days or water exists in grooves, so that welding cannot be carried out, working efficiency is affected, the working strength of welding is high, welding cannot be carried out in place sometimes, the sealing performance of the welded Krah pipes is not good enough, and water seepage or water leakage is easy to occur.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a carat pipe, receive artificial or the welding that the electric current influence caused not to the position infiltration hidden danger when thoroughly solving traditional welding, two rubber rings are sealed, and the seepage is stopped to double-deck protection.

The utility model is realized in such a way that one end of the carat pipe is a bell mouth, the other end of the carat pipe is a socket, a rubber ring is arranged on the socket, and a bell mouth slope is arranged in the bell mouth; the outer surface of the socket is provided with outer grooves for placing outer groove rubber rings and inner grooves for placing inner groove rubber rings at intervals; the outer groove is a step at the end part of the socket.

The end part of the outer groove rubber ring of the utility model is an inclined chamfer, the outer groove rubber ring is sleeved on the step of the end part of the socket, the inclined chamfer thereof is propped against the front end of the socket, and the outer groove rubber ring is provided with inclined convex edges at intervals; the inner groove rubber ring is provided with inclined convex edges at intervals.

For smoother socket joint, the convex edge of the inclined plane of the outer groove rubber ring closer to the end part of the socket is smaller than the convex edge of the inclined plane of the outer groove rubber ring farther from the end part of the socket; the convex edge of the inner groove rubber ring inclined plane close to the end part of the socket is smaller than the convex edge of the inner groove rubber ring inclined plane far away from the end part of the socket.

The utility model has the advantages of convenient and rapid installation, low cost, and easy sheathing by only smearing lubricating oil; the large-diameter pipe is installed without large-scale machines such as cranes and the like, and the tail of the pipe is manually knocked in by using an excavator or a cushion wood board, so that the construction period is shortened, the efficiency is improved, and the installation cost is saved.

Detailed Description

The present invention will be further described with reference to fig. 1-11.

The utility model relates to a carat pipe, one end of which is a bell mouth 1, the other end of which is a socket 2, and a bell mouth slope 3 is arranged in the bell mouth 1; the outer surface of the socket 2 is provided with outer grooves 4 for placing outer groove rubber rings 6 and inner grooves 5 for placing inner groove rubber rings 7 at intervals; the outer groove 4 is a step at the end of the socket.

The end part of the outer groove rubber ring 6 of the utility model is an inclined chamfer 8, the end part step of the socket 2 is sleeved with the outer groove rubber ring 6, the inclined chamfer 8 of the outer groove rubber ring is propped against the front end of the socket 2, and the outer groove rubber ring 6 is provided with an outer groove rubber ring inclined convex edge at intervals; the inner groove rubber rings 7 are provided with inner groove rubber ring inclined plane convex edges at intervals.

For smoother socket joint, the outer groove rubber ring inclined plane convex edge 9 closer to the end part of the socket is smaller than the outer groove rubber ring inclined plane convex edge 10 farther from the end part of the socket; the inner groove rubber ring inclined plane convex edge 11 closer to the end part of the socket is smaller than the inner groove rubber ring inclined plane convex edge 12 farther from the end part of the socket. Also indicated in figures 1, 2 and 3 is an arcuate projection 13 of the carat tube.

The utility model utilizes the elastic deformation characteristic of the natural rubber ring to fill the gap between the bell and spigot, thereby playing a sealing role; the double rubber rings can structurally enable the bell and spigot to form a double-point supporting state, namely, a balanced state is kept, the coincidence degree of the central lines of the bell and spigot is higher, the rubber rings are uniformly compressed along the circumference, and warping does not occur, so that the sealing performance of the bell and spigot of the carat pipe is ensured; if when the geological change arouses carat pipe bell and spigot relative displacement, outer recess rubber ring breaks away from the bellmouth slope and leads to sealed the inefficacy, and the inner groove rubber ring still can exert sealing effect this moment, guarantees that the joint can not leak.

The carat pipe is a high-density polyethylene winding reinforcing pipe. During installation, the chamfer angle of the inclined plane of the outer groove rubber ring on the step at the end part of the spigot just props against the slope of the spigot in the spigot, as shown in figure 3.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
