Abstract
The utility model discloses a stainless steel water pipe joint, which comprises sleeve pipe type shell bodies and fastening nuts, wherein the fastening nuts are in threaded connection with inner threads of the ends of the shell bodies. The utility model is characterized in that a stainless steel short pipe is arranged in the inner middle of each of the shell bodies; both sides of the short pipe in each of the shell body are provided with outer cones with openings; the conical parts of the cones with the openings are sheathed with the cones. Sealing rings are arranged among both sides of the short pipe and the outer cones with the openings. Inner cones, the outer cones with the openings and the short pipe are fastened in each of the sleeve pipe type shell bodies by the fastening nuts. Compared with the existing pipe piece joint, the utility model has the advantages of firm connection, lower cost, good sealing performance, convenient installation and adjustment, environment protection, corrosion resistance and long service life.
Description
Technical field
The utility model relates to metal pipe element interconnection technique field, more particularly relates to a kind of stainless steel water pipe joint.
Background technique
Stainless steel waterpipe is called as real green tubing because of the outstanding advantage of aspect such as itself intrinsic excellent specific property and the Security that brings, reliability, spatter property, serviceability, Economy and environmental protection be attractive in appearance, is of wide application on market.Because according to national GB50261-XX standard, the metallic water pipe joint connects to be forbidden to weld, existing Stainless Steel Tube generally is to connect with heavy wall stainless steel tapping pitch thread, and its shortcoming is that the stainless steel that consumes is many, causes the cost of material height; Too thin stainless steel waterpipe, screw socket is pressed in employing on pipe shaft, boss, the form of band collar connects, it is easy for installation, but it is big to the tubing desired strength, the fabricating cost height, as application number is 01203593, the applying date is February 23 calendar year 2001, and denomination of invention is a kind of patent application of pipe joint, comprises fittings body, place the seal ring that connects in the fittings body on the platform of hole, place the back-up ring on the seal ring, the end is the copper collar of the opening of taper, the corresponding copper collar of endoporus conical end portion place is the nut of taper, its specialization is also to be provided with the fixed pressure ring of opening, and fixed pressure ring is positioned between copper collar and nut.There is the cost height equally in this patent, and owing to parts such as the copper collar is arranged have oxide etch, may cause water to pollute, and structure is more complicated also.
The model utility content
The purpose of this utility model be provide in order to solve above-mentioned deficiency that a kind of cost is low, good seal, corrosion-resistant, environmental protection and stainless steel water pipe joint easy for installation.
The technical solution that the utility model adopts in order to reach above-mentioned effect is as follows:
The stainless steel water pipe joint, comprise bushing type housing and the tightening nut that is spirally connected with the shell ends internal thread, it is characterized in that, be provided with a stainless steel short tube in the middle of in the described housing, be provided with the opening external cone in two side bodies of stainless steel short tube, opening external cone tapering all is socketed in the internal cones, is provided with seal ring between short tube both sides and opening external cone, and tightening nut is fastened on internal cones, opening external cone, short tube in the bushing type housing.Tighten tightening nut, promote internal cones and press to the opening external cone, make opening external cone radial deformation, embrace stainless steel waterpipe, make the stainless steel waterpipe can not be axially displaced, play interconnect function, compress seal ring simultaneously, seal the gap of stainless steel short tube and stainless steel waterpipe, play seal action.
Described short tube both sides inner diameter end is an inner conical surface, and seal ring is arranged on the inner conical surface gap location.
Described short tube both sides inner diameter end also can be step surface, and seal ring is arranged on the step surface place.
Described opening external cone becomes 10-25 ° of angle with level.
Described frame, interior external cone, tightening nut are aluminum alloy or stainless steel material, are the antioxidant anticorrosive materials.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
One, low cost of manufacture, good airproof performance; Adopt the interior external cone, stainless steel short tube and the silica gel sealing ring sealing and fixing that are provided with in the frame, simple and compact for structure; Need not weld and press screw socket, avoid the too thin secondary operations that needs of water pipe at pipe shaft, too thick consumption material again, and the opening external cone is when adopting aluminium material, the intensity of aluminium material is little, behind the radial deformation and the area of contact of stainless steel waterpipe increased, make connection more firm.
Two, corrosion-resistant, the life-span is long, environmental protection; The aluminum alloy or the stainless steel material that adopt are the antioxidant anticorrosive environment-friendly materials, do not have oxidation, etching problem, and aluminium material do not contact with water, have reduced secondary pollution.
Three, to the tubing wide accommodation, easy for installation; Light pipe does not just have specific (special) requirements to the thickness of tubing, bore etc., all can realize connecting, and need not weld, and does not need special tool, rotates tightening nut can install and fix, and dismounting is debugged also and made things convenient for.
Four, the sealing that will take over of the utility model is integrated with fixedlying connected, and has sealing and fixedly connected function simultaneously, satisfies practical requirement through testing its pipe joint strength.
