Abstract
The utility model relates to a reducing slip joint used for installation and maintenance of pipelines of coal gas, heating and city water to realize the direct coupling of pipes of different diameters. The joint of a thick pipe and the joint of a thin pipe are connected through a nut in the mode of circular arc tangency without a sealing gasket. The slip joint has the advantages of convenient maintenance and simple structure.
Description
The utility model relates to a kind of joint that is used for water supply pipe, gas pipe line, caliduct installation and maintenance process.
The union of using in the present various pipeline fitment process can only be convenient to dismounting, is convenient to connect, and but can not be directly will diminish greatly or little change is big.And in the piping erection maintenance process, usually need tubule and extra heavy pipe are coupled together.Run into this situation, use auxiliaries such as the dead joint of reducing, bushing usually.And the dead joint of this reducing is not easy to dismounting, though dismounting is convenient in bushing, union is installed must for the position that diminishes greatly, the dead joint of reducing, spigot, the first-class continuous installation phenomenon of loose joint so often occur, has brought many troubles to installation.And, at the position that diminishes greatly, break down easily, for example in the gas pipe line since coal gas in impurity usually be stranded in the position that diminishes greatly; The phenomenon that then may occur build-up of limescale in the caliduct at the position that diminishes greatly.The reducer fitting of so present use is owing to be not easy to dismounting, thereby uses maintenance very inconvenient.
Task of the present utility model is, design a kind of can be directly the pipe of thick, thin two kinds of different sizes being linked up, be convenient to the isodiameter movable joint of dismounting maintenance, this isodiameter movable joint is without sealing gasket, and should be able in installation process, change parts arbitrarily, to satisfy different needs.
Realize that scheme of the present utility model is: form isodiameter movable joint by extra heavy pipe joint (1), nut (2) and (3) three assemblies of tubule joint, the tubule joint is an exchangeable part.The internal diameter of extra heavy pipe joint (1) is made up of a cylinder and a round platform, its tangent plane along axis is a rectangle and a trapezoidal composition, the internal diameter of tubule joint (3) is made up of the tangent round platform of external diameter of a cylinder and an extra heavy pipe joint, its tangent plane along axis is that a rectangle and both sides are the trapezoidal composition of camber line, and the utility model has 2 inch, 1 1/2 inch, 1 1/4 inch, 1 inch, five kinds of different specifications of 3/4 inch.The isodiameter movable joint of 2 inch can be transformed into 2 * 1 1/2 respectively; 2 * 1/4; 2 * 1; Five kinds of 2 * 1/2 grades.The isodiameter movable joint of 1 1/2 inch can be transformed into 1 1/2 * 1 1/4 respectively; 1 1/2 * 1; 1 1/2 * 3/4; Four kinds of 1 1/2 * 1/2 grades.The isodiameter movable joint of 1 1/4 inch can be transformed into 1 1/4 * 1 respectively; 1 1/4 * 3/4; Three kinds of 1 1/4 * 1/2 grades.The isodiameter movable joint of 1 inch can be transformed into 1 * 3/4; Two kinds of 1 * 1/2 grades.The isodiameter movable joint of 3/4 inch can only be transformed into 3/4 * 1/2 a kind.Following table is the isodiameter movable joint Schedule:
Isodiameter movable joint conversion Schedule
Accompanying drawing 1 is the sectional view after the assembling of 2 inch isodiameter movable joints.
Accompanying drawing 2 is the sectional view after the assembling of 1 1/2 inch isodiameter movable joints.
Accompanying drawing 4 is the sectional view after the 1 inch isodiameter movable joint general assembly.
Accompanying drawing 5 is the sectional view after the 3/4 inch isodiameter movable joint general assembly.
Accompanying drawing 6 is the plan view of extra heavy pipe joint.
Accompanying drawing 7 is the side view of extra heavy pipe joint.
Accompanying drawing 8 is the plan view of nut.
Accompanying drawing 9 is the side view of nut.
Accompanying drawing 10 is the plan view of tubule joint.
Accompanying drawing 11 is the side view of tubule joint.
Accompanying drawing 1 is to accompanying drawing 5, and extra heavy pipe joint (1) is stuck on the nut (2), and nut (2) connects with tubule joint (3).In 2 inch, 1 1/2 inch, 1 1/4 inch, 1 inch, five kinds of different specifications of 3/4 inch, tubule joint (3) can be changed according to different needs, and all size can become a kind to 5 kinds according to changing table transform again, realizes the connection of reducing pipeline.Extra heavy pipe joint (1) connects by nut (2) with tubule joint (3), because extra heavy pipe joint (1) and tubule joint (3) adopt the tangent connecting mode of circular arc when connecting, need not use sealing gasket when therefore connecting, and the energy sealed attachment makes that the use maintenance is very convenient.
The utility model compared with the prior art, the most outstanding advantage is, can be directly the pipe of two kinds of different-diameters be linked up, and realized the direct connection of reducing pipe. And extra heavy pipe joint and the tangent connecting mode of tubule joint employing circular arc, need not use sealing gasket when therefore connecting, make isodiameter movable joint easy-to-dismount more perfect function in the middle of the installation and maintenance process. The utility model is applicable among running water, coal gas, the caliduct installation and maintenance process, realizes that reducing connects, and is convenient to the dismounting maintenance, and simple in structure, easy to use.
