Abstract
An aluminum plastic tube part connection joint is characterized in that the utility mode consists of an external cone bolt joint, an inner cone body press sleeve and a press nut. The external cone body bolt joint has a joint opening connection with the aluminum plastic tube with cone body shape external part, and the cone bottom is provided with a lug boss with an external thread. An arc shape flat surface is formed between the cone bottom and lug boss. The joint end of the inner cone body pressure clamping sleeve has a horn opening shape matching with the arc shape flat surface, and another end thereof is provided with a concave table with the same diameter of the aluminum plastic tube. The utility model has advantages of: 1. easy installment; 2. good sealing; 3. large flowing volume; 4. convenient processing and low cost.
Description
The utility model belongs to a kind of pipe fitting joint, particularly a kind of plastic-aluminum tubing coupling.
At present, general pipe fitting is connected to staight shank and connects, and the external diameter of its pipe fitting approximates the internal diameter of plastic-aluminum pipe, must install O-ring seal additional during installation, uses the spring clip jam-pack again, fixes with gland nut at last.This kind sealing structure is bad, is difficult for processing, installs also inconvenient.
The purpose of this utility model is to provide a kind of plastic-aluminum tubing coupling, and it can overcome the shortcoming that above-mentioned pipe fitting connects, and is a kind of novel pipe fitting joint.
The technical solution of the utility model: a kind of plastic-aluminum tubing coupling, it is characterized in that it is made of external cone screwed joint, internal cones clamping sleeve and gland nut, described external cone screwed joint is that an interface outside that joins with the plastic-aluminum pipe is one cone-shaped, externally threaded boss is with at the awl end, is an arcuation even surface between the awl end and boss; Described internal cones clamping sleeve spigot one end also is the bell mouth shape that can match with above-mentioned arcuation even surface, and the other end has a concave station identical with the plastic-aluminum external diameter of pipe; Said gland nut is sleeved on the external cone screwed joint, and the one end is threaded with screwed joint, and the other end has the concave station of boss and internal cones clamping sleeve to be connected; Above-mentioned external cone screwed joint has retaining leak-stopping groove with being connected of internal cones clamping sleeve on the poppet surface.
Using method of the present utility model: at first earlier the internal cones clamping sleeve is inserted into outside the plastic-aluminum mouth of pipe, then the external cone screwed joint is injected again plastic-aluminum pipe inner spout, make it to magnify with its taper mouth of pipe expansion plastic-aluminum mouth of pipe as far as possible, with gland nut that it is fastening more at last, promptly install.
Superiority of the present utility model is: 1, easily install; 2, good seal; 3, flow is big; 4, easy to process, cost is low.
Further specify present technique below in conjunction with drawings and Examples.
Fig. 1 is the overall structure scheme of installation of the related plastic-aluminum tubing coupling of the utility model.
Fig. 2 is the split element structure schematic representation of the related plastic-aluminum tubing coupling of the utility model.
Fig. 3 is the pipe fitting interface structure schematic representation of prior art.
Wherein: 1 is the external cone screwed joint, and 2 is the internal cones clamping sleeve, and 3 is gland nut, 1a is the arcuation even surface, and 1b is for being with externally threaded boss, and 2a is a horn mouth, 2b is a concave station, and 3a is a boss, and 4 is retaining leak-stopping groove, 6 is the plastic-aluminum pipe, 7 is old pipe fitting joint, and 8 is the split ring card, and 9 is gland nut,, 10 is seal ring.
Embodiment: a kind of plastic-aluminum tubing coupling (seeing Fig. 1,2), it is characterized in that it is made of external cone screwed joint 1, internal cones clamping sleeve 2 and gland nut 3, described external cone screwed joint 1 is that an interface outside that joins with plastic-aluminum pipe 6 is one cone-shaped, externally threaded boss 1b is with at the awl end, is an arcuation even surface 1a between the awl end and boss; Described internal cones clamping sleeve 2 spigots one end also is the bell mouth shape 2a that can match with above-mentioned arcuation even surface 1a, and the other end has a concave station 2b identical with plastic-aluminum pipe 6 external diameters; Said gland nut 3 is sleeved on the external cone screwed joint 1, and the one end is threaded with screwed joint 1, and the other end has the concave station 2b of boss 3a and internal cones clamping sleeve to be connected; Above-mentioned external cone screwed joint 1 has retaining leak-stopping groove 4 with being connected of internal cones clamping sleeve 2 on the poppet surface.
Claims (2)
1, a kind of plastic-aluminum tubing coupling, it is characterized in that it is made of external cone screwed joint, internal cones clamping sleeve and gland nut, described external cone screwed joint is that an interface outside that joins with the plastic-aluminum pipe is one cone-shaped, externally threaded boss is with at the awl end, is an arcuation even surface between the awl end and boss; Described internal cones clamping sleeve spigot one end also is the bell mouth shape that can match with above-mentioned arcuation even surface, and the other end has a concave station identical with the plastic-aluminum external diameter of pipe; Said gland nut is sleeved on the external cone screwed joint, and the one end is threaded with screwed joint, and the other end has the concave station of boss and internal cones clamping sleeve to be connected.
