Abstract
The utility model discloses a PP pipe joint. The PP pipe joint comprises a connection head, a connection column and a connection cover sleeve. The connection head and the connection column are in an integrated forming structure, the connection cover sleeve is movably mounted on the connection column, the connection head is disposed in the connection cover sleeve, a first circular protrusion and a second circular protrusion are arranged on the connection head, a groove structure is arranged between the first circular protrusion and the second circular protrusion, and a seal ring is mounted in the groove structure. According to the PP pipe joint, a water pipe and the connection head are connected through the connection cover sleeve, the seal ring is mounted on the connection head, and the top of the connection head is in an inclined surface structure, so that the seal performance at the connection position is enhanced; the connection position can be effectively protected by the connection cover sleeve, so that the connection position is prevented from begin damaged by the external environment, and the service life is prolonged.
Description
[technical field]
The utility model relates to the technical field of joint, particularly the technical field of PP pipe joint.
[background technique]
PP pipe joint is one of component important in household pipe fitting, mainly be used in: need the conveyance conduit connecting to be connected and sealed, the pipe arrangement that various industrial gas, the fluids such as steam, coal gas, air, heavy oil, oil, chemical industry drug class are transported connects etc.Traditional PP pipe joint great majority directly arrange worm structure and are connected with pipeline on connecting head, the connection sealing of joint and water pipe can be poor, easily there is the phenomenon of seepage, need other measures to carry out leakproof, and the joint of joint and water pipe is directly exposed to outside, the mechanical strength of joint is poor, easily causes damage, working life is lower, promotes difficulty large.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of PP pipe joint, can improve the sealability of the joint of joint and pipeline, has strengthened the protective measure of joint simultaneously, prevents the damage of joint, has extended working life.
For achieving the above object, the utility model proposes a kind of PP pipe joint, comprise connecting head, attachment post and connecting cover cover, described connecting head and the attachment post structure that is formed in one, movable being installed on attachment post of described connecting cover cover, connecting head is positioned at connecting cover cover, and described connecting head is provided with the first annular projection and the second annular projection, between the first annular projection and the second annular projection, be provided with groove structure, seal ring is installed in groove structure.
As preferably, the internal surface of described connecting cover cover is provided with worm structure, and the upper surface of connecting cover cover is connected with outside, and the cross section that connecting cover overlaps is regular hexagon.
As preferably, the outer surface of described attachment post is wavy shaped configuration.
As preferably, described the first annular projection is provided with ramp structure, and the cross section of the first annular projection is less than the cross section of the second annular projection.
As preferably, also comprise flow channel, described flow channel runs through connecting head and attachment post.
The beneficial effects of the utility model: the utility model connects block by employing and comes connecting water pipe and connecting head; and seal ring is set on connecting head; the top of connecting head is ramp structure; strengthen the sealability of joint; and connecting cover cover can effectively be protected joint; prevent that connection part is subject to the damage of external environmemt, has extended working life.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
