Abstract
The utility model discloses a novel polyethylene steel-plastic transition pipe fitting, which comprises a polyethylene part and a metal part main body. The transition pipe fitting is characterized by further comprising a wedged metal sleeve and O-shaped sealing rings. Undercut structures are arranged outside one end of the metal part main body, and the end is inserted into one end of the polyethylene plastic part. A part of the metal part main body is connected with the polyethylene plastic part, and the wedged metal sleeve is sleeved on the periphery of the part. The O-shaped sealing rings are arranged between the metal part main body and the polyethylene plastic part. A chamfer is arranged in the corner of the polyethylene steel-plastic transition pipe fitting. The novel polyethylene steel-plastic transition pipe fitting has a unique structural characteristic; and double O-shaped sealing ring structures are adopted, and mechanical connection is formed between the plastic part and the metal part main body by the wedged metal sleeve, so that a reliable sealing effect is achieved, and a leakage phenomenon is prevented.
Description
Technical field
The utility model relates to a kind of polyethylene (PE) pipeline connection fittings that are used for FLUID TRANSPORTATION fields such as combustion gas, liquid, especially relates to a kind ofly being mainly used in the novel polyethylene steel that plastic pipe is connected with metallic conduit and moulding the conversion pipe fitting.
Background technique
Often occur plastic pipe such as polyethylene and metallic conduit in the fluid-transporting tubing field and change each other, interconnective situation, the wherein main Placement that adopts are that flange connects or steel is moulded conversion and connected dual mode, and this dual mode is mechanical type and connects.Common polyethylene steel-plastic conversion pipe fitting is because structural design is unreasonable, only relies on interference fit between polyvinyl piping materials and steel part to reach the effect of sealing, and sealability is undesirable, occurs the phenomenon of leaking easily.
The utility model has carried out useful improvement in order to overcome above-mentioned defective.
The model utility content
The purpose of the utility model is to solve above-mentioned deficiency of the prior art; Provide a kind of novel polyethylene steel to mould the conversion pipe fitting; Through the design of optimal design steel part back-off structure, set up twice O type sealing configuration, modes such as processing special plastic accessory; Significantly improve the product hermeticity ability, the generation of stopping gas leak phenomenon.
To achieve these goals, the utility model adopts following technological scheme:
A kind of novel polyethylene steel is moulded the conversion pipe fitting; Comprise polyethylene plastic, metalwork main body; Its special way is, also comprises wedge metal sleeve and O RunddichtringO, in the arranged outside of metalwork main body one end back-off structure is arranged; The metalwork main body has an end of back-off to be inserted into an end of polyethylene plastic; The position outer race that is connected with the polyethylene plastic in the metalwork main body is connected to the wedge metal sleeve, between metalwork main body and position that the polyethylene plastic is connected, the O RunddichtringO is installed, and the corner of polyethylene steel-plastic conversion pipe fitting is provided with chamfering;
Further, said back-off structure has the 5-8 road, and an end of back-off structure and polyethylene plastic forms interference fit;
Further, described metalwork main body and polyethylene plastic fitting surface are provided with twice O type circle groove structure, and described O RunddichtringO is arranged in the O type circle groove structure;
Further, the other end of described polyethylene plastic and polyethylene pipe are connected to the plastic pipe end through hot melting way, and the other end of described metalwork main body is connected through screw thread or welding manner with metallic conduit;
Further, said metalwork main body is the steel part main body.
The beneficial effect of the utility model: the utlity model has the particular structure characteristics, adopt two pass O type circle sealing configuration, between plastic and metalwork, form mechanical connection, reach reliable sealing effect, prevent the generation of leakage phenomenon through the wedge metal sleeve.
Description of drawings
An embodiment's of Fig. 1 the utility model structure sectional view.
Reference character: 1. polyethylene plastic; 2. wedge metal sleeve; 3. metalwork main body; 4. back-off structure; 5.O type circle groove; 6.O RunddichtringO.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
The embodiment of the utility model is with reference to shown in Figure 1, and the polyethylene steel-plastic in the utility model is changed mainly by polyethylene plastic 1, wedge metal sleeve 2, and metalwork main body 3, back-off structure 4, O type circle groove 5, O RunddichtringO 6 parts such as grade are formed.Polyethylene steel-plastic conversion pipe fitting adopts the 5-8 road back-off structure 4 through unique design processing, and forms tight interference fit between the supporting with it polythene material according to the product specification size; Both reach the effect that connects two kinds of materials, taken the part seal action simultaneously, simultaneously; Polyethylene steel-plastic conversion pipe fitting adopts special use to add the thick polyethylene accessory; The corner is through special chamfered, when for product enough compressive strength being provided, and forms good being sealed and matched between steel part.
The left end and the polyethylene pipe of polyethylene plastic 1 are connected to the plastic pipe end through modes such as hot melts; 2 pairs of polyethylene plastics of wedge metal sleeve 1 form extruding closely; Guarantee that the polyethylene plastic forms reliable and firm being connected with the metalwork main body, polyethylene steel-plastic conversion pipe fitting adopts highi degree of accuracy wedge metal sleeve, is used for fixing polyethylene plastic 1 and metalwork main body 3; Make both form reliable connection, guarantee intensity and sealing effect.One end of metalwork main body 3 can be connected with the mode of metallic conduit through screw thread or welding, and plays the effect of main body pressure-bearing.
Back-off structure 4 forms interference fit with the internal surface of the plastic 1 of the deformation that is squeezed, and reaches the effect that connects and seal.Polyethylene steel-plastic conversion pipe fitting metalwork main body 3 and polyethylene plastic 1 registration interface designs processing twice groove structure; Be used to install twice O RunddichtringO 6, mould a difficult problem of leaking gas easily between conversion products working of plastics and the steel part thereby thoroughly stopped the common polythene steel.O type circle groove 5 is used to place O RunddichtringO 6.O RunddichtringO 6 receives both compressional deformations between polyethylene plastic 1 and metalwork main body 3, play reliable seal action, thereby stops the generation of escape of liquid problem.
The above mode of execution has only been expressed a kind of mode of execution of the utility model, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
