Abstract

The utility model relates to a flexible pipe, which comprises light-weight core pipe coated with hard PVC mating surface layer through spiral winding and extrusion. In addition, spiral convex on surface layer of flexible pipe is covered with decorative sheet. Surface layer of flexible pipe is internally provided with terylene line, which is distributed lengthways on the surface of core pipe. The utility model has the advantages of longer service life, convenient installation, heat resistance and pressure resistance and has various colors and shapes. In addition, it has effectively eliminates water leakage due to internal pipe crack and joint fall-off and shows excellent effects of water and gas transmission and is of great value of extensive promotion and application.

Description

Flexible pipe

Technical field

The utility model relates to a kind of flexible pipe.

Background technique

The shower hose of being sold all is to be formed by connecting with Stainless Steel Tube, copper pipe hitch in the market, and wherein interior pipe all adopts rubber or flexible PVC material.But phenomenons such as in the using process formula, the interior tracheal rupture of frequent appearance, joint come off, hitch cracking, generation causes leaking.And Chinese patent 00255860.2 disclosed a kind of " sanitary bathing ware spiral reinforced polyvinyl chloride flexible pipes ", it is to be coated with the soft PVC coating outward by the herd polyvinyl chloride material sandwich layer to adopt spiral winding method extruding bonding forming.But because the sandwich layer of this flexible pipe adopts is herd polyvinyl chloride material, therefore also can have and traditional Stainless Steel Tube, copper pipe existing in the crackly defective of pipe.The joint of this flexible pipe is still the same with the joint of traditional Stainless Steel Tube, copper pipe in addition, adopt punching press to be formed by connecting, therefore fundamentally do not solve by joint come off, hitch ftractures caused seepy question.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of can solve the flexible pipe that the pipe water leakage phenomenon takes place at above-mentioned prior art present situation.

Another technical problem to be solved of the utility model is to provide a kind of except having long service life, easy for installation, heatproof, good pressure-resistant performance, and can realize pipe color, the diversified flexible pipe of profile.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: this flexible pipe be by two heads at pipe establish respectively one with pipe welding all-in-one-piece joint.

Described pipe can adopt flexible nonmetallic tubing or metallic hose.

Described flexible nonmetallic tubing is one to be coated with spiral by flexible PVC core pipe and to twine and to be squeezed into cancavo-convex hard PVC skin and to form, and its helix angle can be chosen between 10 °～15 °.And for the profile that makes flexible pipe is more attractive in appearance, in the outer spiral salient of flexible pipe position, also can be coated with the rising on the core tube-surface that be distributed in that is coated with in cosmetic sheet and the flexible pipe skin along interior length of tube direction layout and prevents that pipe from stretching and the polyester thread of decorating action.

In order to prevent to be contained in the screw cap-falling on the pipe, on described joint, also be formed with flange.

Compared with prior art, advantage of the present utility model is: by flexible pipe provided by the utility model, because joint is to be fused into one with pipe, so the problem that does not exist joint to come off, thereby can not leak; Simultaneously core pipe of this flexible pipe and skin are respectively to be made by soft and hard PVC material, thus have long service life, nontoxic, heatproof, good pressure-resistant performance, can be crooked arbitrarily, installation is easy to connect etc. advantage; In addition because skin is to twine extrusion molding by spiral, and be coated with the metal finishing sheet and prevent that pipe from stretching and the polyester thread of decorating action, thereby make the profile of flexible pipe more attractive in appearance, color is abundanter, overcome stiff, the single defective of existing flexible pipe moulding, can satisfy different clients' demand.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1-Figure 3, the utility model flexible pipe body 1 is to be formed by concavo-convex skin 14 bondings of the wrapped one deck in core pipe 11 outsides, its middle core pipe 11 adopts nontoxic middle flexible PVC material to make, outer 14 adopt the coiling of hard PVC material helical to extrude forms, and its helix angle can be chosen between 10 °～15 °.And more attractive in appearance and prevent that pipe is stretched for the profile that makes flexible pipe, be provided with the polyester thread of arranging along interior length of tube direction 12 on the surface of interior pipe, be covered by in outer 14.And in outer field boss, being coated with metal finishing sheet 13, this cosmetic sheet 13 is simultaneously wrapped outside core pipe 11 with outer 14.Because outer 14 are transparence, so the surface of

cosmetic sheet

13 and 12 pairs of pipes of polyester thread played the excellent decoration effect, by cosmetic sheet and the decorative rib of selecting different colours for use, can make the profile of flexible pipe, color change various.The flexible pipe of making thus is hard and soft to be had concurrently, heat-resisting, withstand voltage, any required angle of flexible one-tenth is installed easy to connect during use.

Be respectively equipped with a joint 3 at two of pipe, to defend sanitary equipment different by the joint that punching press is formed by connecting with flexible pipe with general shower hose or cupboard for it, this hose coupling adopts special composite plastic, form through high temperature and the extruding welding of pipe two ends, it is applicable to the welding of metallic hose (as Stainless Steel Tube, copper pipe etc.) two end connectors.In addition for the nut 2 that prevents to be contained on the flexible pipe comes off, the flange 31 that on joint, also is formed with.The great advantage of this joint be exactly do not come off, water-tight.

Claims

1, a kind of flexible pipe comprises pipe body (1), it is characterized in that: be respectively equipped with at described pipe two one with pipe welding all-in-one-piece joint (3).

2, flexible pipe as claimed in claim 1 is characterized in that: described pipe is flexible nonmetallic tubing or metallic hose.
