Abstract
The utility model discloses a joint with corrugated plastic pipes. The joint comprises a joint body, a step is arranged in the middle of the joint body, two parts different in diameter of the joint body are formed by the step, the inner wall of the joint body is a smooth face, the outer wall of the joint body is corrugated, and the two corrugated pipes different in diameter are inserted into the two ends of the joint body respectively. According to the joint with the corrugated plastic pipes, the corrugated pipes different in diameter can be connected in series, the strength of the joint body can be increased through the corrugated outer wall, the service life of the joint body is prolonged, the corrugated pipes are prevented from being broken from the joint in the use process, and maintenance cost is saved.
Description
Technical field
The utility model relates to pipe joint, relates in particular to a kind of band ripple plastic pipe union.
Background technique
In municipal engineering, conventionally adopt bellows as sewage pipe or other water delivery pipes, when installation, due to the limited length of every bellows, relate to bellows connectivity problem is installed.At present, between adjacent two bellowss, generally need to joint be set to can easily pipeline be together in series in construction.
Current plastic pipe union generally comprises joint body, and joint body inside and outside wall is all even surfaces, in the opposite end distribution grafting plastic pipe union of adjacent corrugations pipe, thereby pipeline is together in series.Because the inside and outside wall of joint body is even surface, so the intensity difference of plastic pipe union.In using process, bellows is through the plastic pipe union place fracture of being everlasting.Meanwhile, existing joint body two ends diameter is consistent, can only be connected in series the bellows that diameter is identical, and cannot the different bellows of connection diameter.
Summary of the invention
In order to overcome the deficiencies in the prior art, the band ripple plastic pipe union that provides a kind of intensity high, easy for installation is provided the purpose of this utility model.
The technical solution of the utility model is: a kind of band ripple plastic pipe union, it comprises joint body, described joint body middle part is provided with step, joint body forms two different parts of diameter by this step, described joint body inwall is even surface, outer wall is corrugated, and two bellowss of different-diameter are plugged on respectively in joint body two ends.
The utility model adopts above structure, due to joint body two ends diameter difference, thereby can be used for connecting the different bellows of two diameters.Meanwhile, because the outer wall of joint body is corrugated, enough bear outside radial pressure, make joint body that certain bending and stretching occur under ambient pressure, thereby the compressive strength and the degree of drawing that have increased joint body, prevent in use, bellows ruptures at joint body place.
Described joint body inwall is provided with spacer ring at step place, thereby facilitates joint body two ends grafting bellows.
Described joint body is by plastic rubber shaping, and it is convenient for production.
In the wave heave of the corrugated outer wall of described joint body, be provided with cavity, in cavity, be embedded with plastic strip, can improve the ring stiffness of joint body, further improve the intensity of joint body, extend the working life of bellows.
The utility model band ripple plastic pipe union, it not only can make the bellows serial connection of different-diameter, and its corrugated outer wall also can strengthen the intensity of joint body, the working life of extending connector body, avoid bellows in use to disconnect in joint, save maintenance cost.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model embodiment 1 the structural representation with ripple plastic pipe union;
Fig. 2 is the utility model embodiment 2 the structural representation with ripple plastic pipe union.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of band of the utility model ripple plastic pipe union, it comprises joint body 1, described joint body 1 middle part is provided with step 2, joint body 1 forms two different parts of diameter by this step 2, described joint body inwall 11 is even surface, and outer wall 12 is corrugated, and two bellowss of different-diameter are plugged on respectively in joint body 1 two ends.
Described joint body 1 is by plastic rubber shaping, and it is convenient for production.
Described joint body inwall 11 is provided with spacer ring 3 at step place, thereby facilitates joint body 1 two ends grafting bellows.
As shown in Figure 2, on embodiment 1 basis, in the wave heave of the corrugated outer wall 12 of described joint body, be provided with cavity 13, in cavity 13, be embedded with plastic strip 4, can improve the ring stiffness of joint body 1, further improve the intensity of joint body 1, extend the working life of bellows.
The above two kinds of embodiments' of the utility model band ripple plastic pipe union, due to joint body 1 two ends diameter difference, thereby can be used for connecting the different bellows of two diameters.Meanwhile, because the outer wall 12 of joint body is corrugated, enough bear outside radial pressure, make joint body 1 that certain bending and stretching occur under ambient pressure, thereby the compressive strength and the degree of drawing that have increased joint body 1, prevent in use, bellows is in joint body 1 place fracture.
Claims (4)
