Abstract
The utility model relates to a pliers-pressing pipe fitting with a metal-plastic mutually embedded structure. The utility model consists of a plastic pipe fitting body, a metal core, an inner-outer tooth connecting body, a seal ring and a stainless steel sleeve. The pipe fitting body, the core and the inner-outer tooth connecting body all adopt the metal-plastic mutually embedded structure. A plurality of annular grooves are arranged at the back end of the core, and a plurality of radial holes are cut along a circle direction. And the seal ring is arranged in the annular groove, and three hackle annular grooves and two seal ring grooves are arranged on the front-middle part of the core. The utility model has the advantages that the material cost and the use cost are low; the seal connection is reliable; and the utility model is more suitable for a big-specs pipe. And the structure of the utility model is also suitable for two-way pipe fittings and multi-way pipe fittings.
Description
The utility model relates to the pipeline connection technology field, particularly a kind of clamping and pressing fitting that adopts plastic-metal phase embedding structure.
Existing plastic-aluminum combined effective clamping and pressing fitting is made up of pipe fitting body 11, core body 12, inside and outside tooth connecting body 13, in general, this three part is all used with a kind of metal such as brass and is made an overall structure, core body 12 middle front parts are provided with three sections zigzag fashion annular grooves and two place's seal grooves, all are connected and sealed with rubber seal when pipe fitting two ends and pipe join.The deficiency of said structure is: when on the tubing that is applied in big specification, and the pipe fitting comparison heaviness that just seems, the cost of material height uses price expensive.
The purpose of this utility model is to provide the clamping and pressing fitting of the employing plastic-metal phase embedding structure that a kind of cost is lower, weight is lighter.
The purpose of this utility model is achieved in that a kind of clamping and pressing fitting that adopts plastic-metal phase embedding structure, comprise pipe fitting body (21), core body (22), inside and outside tooth connecting body (23), this body sealing ring (24), plug washer (25), stainless steel sleeve (26), core body (22) middle front part is provided with three sections zigzag fashion annular grooves and two seal grooves, and metallic core (22), the inside and outside tooth connecting body (23) of metal adopt embedding structure mutually with plastic pipe body (21).Described core body (22) rear end periphery is provided with many circular grooves (223), and along circumferentially having 2-5 radial hole 224, core body (22) rear end endoporus is provided with lining and moulds cylndrical surface (225), and its diameter is greater than the diameter of front end inner hole surface (226).In core body (22), be provided with a circular groove (223) at least, this body sealing ring (24) is housed on it.Described core body (22) rearward end is provided with the hexagon cylinder.The material of described core body (22) adopts copper or stainless steel.Said structure is equally applicable to two logical and multi-way pipe fittings.
Advantage of the present utility model is that cost of material and user cost are low, be tightly connected reliable, when being applied to have big generalization than traditional simple brass pipe fitting on the big specification tubing.That the technical program is applicable to fully is two logical, on threeway and the multi-way pipe fitting, also be suitable for place such as chemical industry and use.
