Abstract
The utility model belongs to the technical field of connection hoses, and relates to a hose joint, in particular to a composite hose joint. The composite hose joint comprises a joint body and is characterized in that the center of the joint body is provided with an axially-through water flow channel; an axially-through air flow channel is arranged at the periphery of the water flow channel; the side part of the joint body is provided with an air hole communicated with the air flow channel; one end of the joint body is fixedly provided with an end cover; the end cover blocks one end of the air flow channel, and the center of the end cover is provided with a through hole communicated with the water flow channel. The composite hose joint has the advantages that (1) the design is reasonable, the structure is simple, the stability between a water pipe channel and an air pipe channel is good and the conveying effect is good; (2) the structure strength is high, the sealing performance is good, and the adaptability to different site temperatures can be achieved, so that the adaptability is strong; and (3) the cost and the maintenance cost are low and the service life is long.
Description
Technical field
The utility model belongs to connecting hose technical field, relates to hose coupling, especially relates to a kind of composite hose coupler.
Background technique
Connector is all being played the part of very important role in various fields, the conversion adapter that it is mainly used in various switch sites, have for circuit branch, merging, commutation, have for sealing, waterproof etc.Hose coupling belongs to a kind of connector, thereby hose coupling is convenient to form delivery line for connecting hose.In prior art, hose coupling generally can only be carried single flowing medium in equipment, because the water of carrying and gas can not meet synchronous working under specific temperature, pressure simultaneously, easily device is caused damage.
For example, Chinese patent literature discloses a kind of hoop-tight organization [application number: 201020608759.5] of water supply line fittings body, comprises fittings body, of fittings body, is embedded with copper insert, the outer armlet that it is characterized in that described fittings body has iron ring, iron ring and fittings body outer wall phase banding.By the outer armlet at fittings body, there is one deck iron ring, because iron material intensity is good, fusing point is high, be difficult for temperature distortion, be fixed on fittings body outer wall, firm with fittings body banding, avoid fittings body to be heated after produce expand, guaranteed quality and the working life of fittings body, and improved the intensity of fittings body outer wall and increased effect attractive in appearance.
Although such scheme can make joint normally work at different temperature, and the intensity of fittings body and aesthetic good, it is reasonable not that such scheme still exists design, can not realize the function of aqueous vapor synchronous working, cannot reach the specific demand of people.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, and device join strength is high, encapsulation and the effective composite hose coupler of conveying.
For achieving the above object, the utility model has adopted following technical proposal: this composite hose coupler, comprise fittings body, it is characterized in that, described fittings body center has the flow channel of axial perforation, is arranged with the air-flow path of axial perforation at flow channel outward, is provided with the pore connecting with air-flow path at the sidepiece of fittings body, one end of described fittings body is fixed with end cap, and described end cap shutoff has the through hole connecting with flow channel in one end of air-flow path and at end cap center.Obviously, connect the join strength that can strengthen between water air pipe by such structure, guarantee the stable input output of current and air-flow, the pressure of flow channel and air-flow path will reach steady state simultaneously.
In above-mentioned composite hose coupler, between described end cap and fittings body, be provided with the sealing configuration that can make flow channel and air-flow path mutually isolate.By sealing configuration, can guarantee the sealing of this device.
In above-mentioned composite hose coupler, described fittings body one end is provided with ring-shaped step at least one, and described end cap is provided with at least one outer ring step, and described interior ring-shaped step and outer ring step coincide correspondingly mutually.Adopt said structure, fittings body can be connected more closely with end cap, and the sealing between flow channel and air-flow path also can be protected.
In above-mentioned composite hose coupler, between described end cap and fittings body, by fastening piece, be fixed together.
In above-mentioned composite hose coupler, described sealing configuration comprises at least one O-ring seal being arranged between end cap and fittings body.The sealing of described O-ring seal energy ensuring equipment.
In above-mentioned composite hose coupler, described fittings body is provided with connecting thread section away from one end outer wall of end cap.This connecting thread section can be connected with other devices composite hose coupler.
Compared with prior art, the advantage of this composite hose coupler is: 1, reasonable in design, simple in structure, having good stability between water pipe channel and air pipe passway, carries effective.2, structural strength is high, and good airproof performance can be adapted to different scene temperature, strong adaptability.3, cost and maintenance expenses are low, long service life.
