Abstract

The utility model relates to the improvement of a plastic cement tube which is formed by sheathing inner tubes and outer tubes made of two different materials. The utility model is characterized in that the outer tubes are composed of PVC material, and the inner tubes are composed of PE or PP of non-toxicity material. The upper surface of the inner tube has multiple projections, the upper part of the projection is big and the lower part of the projection is small. The inner surfaces of the outer tubes are matched with the shapes of the projections of the inner tubes to form projection grooves with the same number and the same shape, so that the inner tubes and the outer tubes can be mutually and crossly sheathed with each other into integration. When the plastic cement tube is used as a drinking water delivery tube, no toxicity is generated.

Description

Plastic cement pipe

The existing conduit pipe that is used to food or potable water, the material that it adopted has the PE(polyethylene), the PP(polypropylene) or the PVC(PVC) the plastic cement pipe, but there is not pore when pure PE, PP plastic cement Guan Yinqi moulding, therefore can't make it become a disjunctor with the sleeve pipe gummed between the pipe in twos, quite inconvenient, be an avirulent material but its maximum benefit is it.Moreover, as PVC plastic cement pipe, when being used in indoor decoration or water power pipe arrangement traditionally, for being fit to the variation of landform or region, can make it softening by fiery bake mode, and when it is still unhardened, can be easily with root in twos with material pvc pipe gluing fit to finish piping work, but the water pipe of general potable water is if adopt above-mentioned fit mode, because pvc pipe is through this processing or meet and can decomposite fatal toxin, the poison-dioxin in century when hot, so will produce greatest injury to human body, but convenient because of its pipe arrangement, it can't be abandoned sometimes need not at all.The inventor independently uses the disappearance of making in order to improve above-mentioned two materials, and think to add improvement, the utility model is PE or PP material for the tool internal layer, skin is the plastic cement pipe of PVC material, making its part that contacts with potable water is non-toxic material, takes over but be easy to gummed.

The purpose of this utility model is that a kind of avirulent drinking-water usefulness pipe is being provided, but is easy to glue together the plastic cement pipe of adapter, removes the harm to human body, makes people that one safe, clean drinking water quality can be arranged.

And characteristics of the present utility model are to be to utilize avirulent PE or PP material to make interior pipe, and at a plurality of prominent bodies of interior tube-surface tool, make and can overlap integrator with outer field pvc pipe, and form a kind of plastic cement pipe of inner and outer pipe material inequality.

As for plastic cement pipe of the present utility model, its structure characteristics then is person as shown in the drawing, and details are as follows:

Brief Description Of Drawings

Fig. 1: External view of the present utility model.

Fig. 2: sectional view of the present utility model.

Fig. 3: view profile embodiment one of the present utility model.

Fig. 4: view profile embodiment two of the present utility model.

Fig. 5: view profile embodiment three of the present utility model.

Please consult shown in Figure 1 earlier, be external view of the present utility model, shown in the figure, the outer tube 1 that the utility model system is made by a PVC material, and one 2 sockets of interior pipe of making by avirulent PE or PP material make the plastic cement pipe of one, pipe 2 is a soft body wherein, and in this, have a plurality of prominent bodies 21 on the outer surface of pipe 2, should prominent system be last big, following little shape, prominent body 21 moulding of pipe in outer pipe internal surface then cooperates and forming with number and with the prominent body groove 11 of shape, so make in it, outer tube 1,2 behind fit, forms a closely not segregative plastic cement pipe.

Be with state as above-mentioned inner and outer pipe 1,2 fit sets, as shown in Figure 2, can very ideally soft nontoxic interior pipe 2 be coated within the outer tube 1 of PVC material, when making the quilt of this plastic cement pipe apply to conduit pipe in the potable water, have only its nontoxic interior Guan Yushui contact, make the Consumer can feel at ease to drink.

Moreover the interior rostrum body 21 shown in Fig. 3,4,5, it is up big and down small shape as described above, become trapezoidal, rhombus, circular arc or polygonal person but it can freely be arranged in pairs or groups, its purpose is to come off between the inner and outer pipes for preventing, makes the utility model utilization scope more extensive.

Again the utility model adopt outer tube make for the PVC material and interior pipe be PE or PP make soft in pipe, can be by the material of PVC to carry out the adapter work between tube and tube, but adopt avirulent interior pipe, can make when being applied to conduit pipe its Security better, and sizable otherness is arranged with the plastic cement pipe of the unisexuality material of commonly using, and when being applied to the pipe arrangement in frigid zone or the frequent area of earthquake as if quilt, the Yin Qinei pipe is soft PE material, split or when making outer tracheal rupture because of colder becoming fragile with the PVC material of outer tube even if be because of earthquake, its interior pipe also is difficult for breaking and the water of water pipe is leaked outside, thereby makes the utility model more meet initiative and practicability.

Claims

1, a kind of plastic cement pipe is characterized in that, be by a PVC outer tube, with an avirulent of making by PE or PP material soft in pipe institute fit form, make this plastic cement pipe be easy to be taken over but when it is used to conduit pipe avirulent more.

According to the plastic cement pipe of claim 1, it is characterized in that 2, said inner tube outer surface cording has a plurality of prominent bodies and can combine with the same number of the internal surface of the outer tube prominent body groove with shape, makes its inner and outer pipe can wear the closely not segregative plastic cement pipe of formation mutually.

According to the plastic cement pipe of claim 1 or 2, it is characterized in that 3, said prominent system is last big, following little shape, not segregative situation can be trapezoidal person behind its fit.

According to the plastic cement pipe of claim 1 or 2, it is characterized in that 4, said prominent system is last big, following little shape, not segregative situation can be circular arc person behind its fit.

According to the plastic cement pipe of claim 1 or 2, it is characterized in that 5, said prominent system is last big, following little shape is linked in the not segregative situation person that can be the polygonal in it.
