Description
Technical field
The utility model is related to water pipe head technical field, more particularly, to a kind of eccentric joint.
Background technology
Water pipe head is for connection to a kind of part of water pipe.Water pipe head can be divided into by occupation mode：External screw thread is terminated
Formula water pipe head, bite type water pipe head, self-hard water pipe head.External screw thread termination formula water pipe head brass alloy material pressure
Casting is formed, plating nickel on surface, frosted or chromium plating；Close structure, pore-free, intensity is high.Bite type water pipe head can be by non-threaded
Steel pipe is connected with flexible pipe, saves set wire process, need to only be screwed in screw；Close structure, intensity is high.Self-hard water pipe head
The equipment line outlet of the steel pipe of non-threaded or non-threaded can be connected with flexible pipe, save set wire process；Using brass alloy material
Die casting is formed, and surface is zinc-plated, frosted or chromium plating；Close structure, intensity is high.Be widely used in top-grade building, it is hotel, hospital, big
Tall building, gymnasium, museum, institutional settings, villa, residential quarters.
In terms of draining, when needing to connect the drainpipe of different bores, it is necessary to use water pipe head.And in order to
Entrance pipe pressure drop is reduced, and when bigger than discharge connection one or two grade of entrance pipe, it is necessary to use eccentric reducing joint
Connect.The adaptability that but existing eccentric reducing joint is installed is not fine, and after installation unsightly, and junction contacts are close
Seal effect not good, pipe and leak may be taken off under hydraulic pressure.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of eccentric joint simple in construction, with low cost, should
The adaptability and sealing that water pipe head is installed are all fine, are not in de- pipe and drainage.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of eccentric joint, including in bending
The joint body of shape, described joint body is included in upper pipe portion, transition pipe portion and down leg, described joint body provided with upper
Tube chamber, middle tube chamber and lower tube chamber, described middle tube chamber are located between upper tube chamber and lower tube chamber, and the aperture of described upper tube chamber is from pipe
The upper port of chamber is gradually reduced to middle tube chamber, and described upper tube chamber and the angular range of middle tube chamber junction are 140 ~ 160 °, institute
The axial line for the middle tube chamber stated and the angular range of vertical direction are 11 ~ 13 °, the axial line and vertical direction of described lower tube chamber
Parallel, the outer tube wall of described upper pipe portion is provided with G1/2B pipe screw threads, and the outer tube wall of described down leg is provided with G3/4B pipe spiral shells
Line, the pipe screw thread length range of described upper pipe portion is 21 ~ 22mm, the pipe screw thread length range of described down leg for 19 ~
21mm。
Further improved as the utility model, the diameter range at the upper end open of described upper tube chamber is 13 ~ 16mm,
17 ~ 22mm of diameter range of described lower tube chamber, the diameter range of described middle tube chamber is 9 ~ 11mm.
Further improved as the utility model, between the described axial line of upper pipe portion and the axial line of down leg between
It is 5 ~ 7mm away from scope.
Further improved as the utility model, described upper pipe portion external diametrical extent is 18 ~ 20mm, described down leg
External diametrical extent is 24 ~ 26mm.
Compared with prior art, the utility model has the advantage of adaptability and close that is simple in construction, with low cost, installing
Envelope property is not in the phenomenon of de- pipe and leak very well.
