Abstract
The utility model discloses a plastic pipe for water supply. The plastic pipe for the water supply comprises a pipe body, one end of the pipe body is a bell end with a flaring, and the other end of the pipe body is an inserting opening. A seal ring annular groove used to contain an elastic seal ring is arranged in the bell end, a chamfer is arranged on the end portion of the inserting opening, and a chamfer corresponding to the chamfer on the end portion of the inserting opening is arranged on the inner surface of the bell end. According to the plastic pipe for the water supply, the chamfer is arranged on the end portion of the inserting opening, and therefore in the process of mounting the plastic pipe, abrasion to the elastic seal ring caused by the inserting opening is reduced, the mounting process is more smooth and faster, and after the plastic pipe is mounted, an connecting opening is stable and high in sealing performance.
Description
Technical field
The utility model relates to a kind of plastic tube, more particularly, relates in particular to a kind of feedwater and uses plastic tube, is mainly used in city water system, raw material of industry conveyance conduit, agricultural irrigation pipeline etc.
Background technique
At present; Feedwater mainly contains elastic seal ring formula and two kinds of solvent welding formulas with the Placement of plastic tube, because solvent welding technology harshness must leave standstill curing ability water flowing pressure testing in 24 hours after bonding; Handling has the interface seepage that very easily causes not in place slightly, influences the normal use of tubing.Though and the Placement of elastic seal ring formula is fast simple, because the socket end of existing tubing is not sufficiently oily, cause tubing in installation process, installation has some setbacks, and damages O-ring seal easily, thereby has influenced the sealability that tubing is installed.
The model utility content
The purpose of the utility model is the deficiency to above-mentioned existing technology, provides a kind of feedwater to use plastic tube, and the installation of this type tubing is convenient, the installation rear port is stable, sealing is high.
For realizing above-mentioned purpose; Plastic tube is used in the feedwater that the utility model provided, and comprises the tubing main body, and an end of said tubing main body is the bellmouth of enlarging; The other end is a socket; In said bellmouth, be provided with the seal ring annular groove of depositing elastic seal ring, the end of said socket is provided with chamfering, and the internal surface of said bellmouth is provided with and the corresponding chamfering of the chamfering of socket end.
Chamfering span in the chamfering of said socket end and the bellmouth is 10～20 degree.
The utility model is through being arranged to chamfering with the end of socket, and tubing can reduce the wearing and tearing of socket to elastic seal ring in the process of installing like this, make installation more smooth and easy quick, and the installation rear port is stable, sealing is high.
Description of drawings
Fig. 1 is the structure sectional view of the utility model feedwater with plastic tube;
Fig. 2 is that the utility model feedwater is with the structure sectional view of plastic tube when connecting.
Among the figure: 1-tubing main body; The 2-bellmouth; The 3-socket; 4-seal ring annular groove; The 5-elastic seal ring.
Embodiment
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Consult illustrated in figures 1 and 2ly, plastic tube is used in the utility model feedwater, comprises tubing main body 1, and an end of said tubing main body 1 is the bellmouth 2 of enlarging, is used for the socket end of another plastic tube of socket joint, and the other end of tubing main body 1 is a socket 3.In bellmouth 2, be provided with seal ring annular groove 4, elastic seal ring 5 places in the seal ring annular groove 4, with the sealing that guarantees that plastic tube connects.End at socket 3 is provided with chamfering, so that reduce the wearing and tearing to elastic seal ring 5, the angle beta span of this chamfering is 10～20 degree, preferred 15 degree.Be provided with the corresponding chamfering of chamfering with socket 3 ends at the internal surface of bellmouth 2, the angle [alpha] span of this chamfering is consistent with the span of undercut ss, is 10～20 degree, preferred 15 degree.
Claims (2)
