Description

A kind of water pipe adapter commonly used

(1) technical field

The utility model relates to a kind of water pipe adapter commonly used, belongs to conduit pipe accessory commonly used or optional equipment.

(2) background technique:

At present, the extensive application of high pressure hose and plastic-aluminum pipe reduces the installation cost of hot-water heating engineering greatly, because it is easy for installation, it is more easy that the low and ductility that be suitable for the characteristic, particularly high pressure hose of various occasions of expense installs it, makes it more and more be subjected to people's favor.But in installation and using process, we find, because two of every high pressure hose all is fixedly coupled device.So producer can only be with specific several specifications, the demand different to each specification according to market (rely on a large amount of market surveys at any time and sell order and determine) produced and supplied to market.Therefore, the user generally can only select to satisfy the demands greater than the specification of actual demand when choosing.Secondly, in installation or using process, no matter be the damage Anywhere of flexible pipe or joint, whole pipe just can not be used again.Cause waste.Because the particularity of its structure, recycle also pretty troublesomely, very easily pollute.The plastic-aluminum pipe does not then have the metalwork of this worry, particularly joint in installing and using process, generally be not easy to break down.And the length of plastic-aluminum pipe also can be determined as required voluntarily.But the seal ring on the aluminium plastic pipe joint is easily aging, very easily damages during installing/dismounting, and it is also not too convenient to change.And, because of the too late high pressure hose of the flexibility of plastic-aluminum pipe, so the usage space of plastic-aluminum pipe also has certain limitation.

(3) goal of the invention

The design mainly solves the connectivity problem of flexible pipe, plastic-aluminum pipe and other pipeline, pipe fittings and sanitary equipment, overcomes the deficiency that exists in the existing design, makes installation, maintenance, the using process more environmental protection, more economical, more convenient that becomes.

(4) summary of the invention

A kind of water pipe adapter commonly used is made up of adapter body, connection mouth, taper pipe, tube chamber, joint, it is characterized in that: adapter body, connection mouth, taper pipe are as a whole, tube chamber and joint are positioned at its axial location, the card pipe is between connection mouth and taper pipe, the annular concave-convex groove is affixed on the taper pipe outer wall closely with water pipe, the nut spiral is connected in connection mouth, is used for the card pipe is pressed into the connection mouth inner chamber.

(6) embodiment

The utility model is a pipe fittings as the connection set of threeway, four-way, valve, water nozzle, joint etc. and flexible pipe.Now the Placement with internal thread joint and flexible pipe is an example, is described as follows: (one), structure constitutes: adapter body (1), connection mouth (6), taper pipe (7) are as a whole.Tube chamber (9) and joint (8) are positioned at its axial location; Card pipe (3) is positioned between connection mouth (6) and the taper pipe (7), utilizes the annular concave-convex groove in it that flexible pipe (or plastic-aluminum pipe) (5) is affixed on taper pipe (7) outer wall closely during installation, makes its sealing; Nut (2) spiral is connected in connection mouth (6), is used for card pipe (3) is pressed into the connection mouth inner chamber.

Working principle and using method: before the use, nut (2), card pipe (3) are enclosed within on the flexible pipe (or plastic-aluminum pipe) (5) by shown in Figure 2; Flexible pipe (or plastic-aluminum pipe) (5) is enclosed within on the taper pipe (7), flexible pipe is advanced, make its termination be horn-like; Nut (2) is screwed on the connection mouth (6); By rotating screw cap (2) will block pipe (3) thus being pressed into the connection mouth inside groove is stuck in flexible pipe (or plastic-aluminum pipe) (5) between taper pipe (7) and the card pipe (3).During dismounting, loosen nut can easily unload card pipe (3) and flexible pipe (or plastic-aluminum pipe) (5).

Manufacturing material: sealing gasket (4) can be selected common rubber cushion or high temperature resistant rubber cushion for use, and other members can adopt material such as metal.

The design can solve the company of flexible pipe, aluminium-plastic pipe and other pipeline, pipe fitting and sanitary equipment Connect problem. It mainly contains the characteristics of the following aspects:

(1), the design makes high-pressure hose in use also as aluminium-plastic pipe, can basis Need the intercepting random length, reduced unnecessary waste;

(2), because joint can separate with high-pressure hose. So, install, use or During maintenance, material wastage rate is obviously reduced, and installation and the maintenance cost of pipeline also obtain Significantly reduce. Simultaneously, also so that the recycling of waste material becomes simpler, easier, Reduced environmental pollution;

(3), because be used for connecting and fixedly the member of flexible pipe (or aluminium-plastic pipe) be gold Belong to material, and the particularity of the connected mode of the two, even dismounting is not fragile yet repeatedly.

(4), the production process of more traditional high pressure hose is produced, is planned to become simpler, easier, thereby reduced cost of production.

Claims (1)

1, a kind of water pipe adapter commonly used is made up of adapter body (1), connection mouth (6), taper pipe (7), tube chamber (9), joint (8), it is characterized in that: adapter body (1), connection mouth (6), taper pipe (7) are as a whole, tube chamber (9) and joint (8) are positioned at its axial location, card pipe (3) is positioned between connection mouth (6) and the taper pipe (7), the annular concave-convex groove is affixed on taper pipe (7) outer wall closely with water pipe (5), nut (2) spiral is connected in connection mouth (6), is used for card pipe (3) is pressed into the connection mouth inner chamber.
