Abstract
The utility model discloses a pipe fitting used for connecting metal plastic composite tubes, which is characterized in that the pipe fitting comprises a grip body (1), an opening ring (2), an inner bush (3) and a sealing ring (4); the grip body adopts a bisect structure and an elastic opening ring is arranged between the grip body and the metal surface of the end of the composite tube (paring the outer plastic when fixing); the tight locking force of the bolt can be distributed to the outer surface of the metal layer of the composite tube by the elastic opening ring in order to make the pipe fitting combine with the pipe tightly; a steel inner liner with a sealing ring has a good sealing performance and can bear high radial force and axial force; all the parts adopt innoxious antisepsis measures such as spraying anti-corrosive paint, plating and chemical plating, therefore the integral corrosion resistance performance is very high.
Description
The utility model relates to a kind of pipeline connection and uses pipe fitting, specifically is a kind of composite metal-plastic pipe connection pipe fitting.
The composite metal-plastic pipe pipe fitting of known technology has the FERRULETYPE of employing Placement, and the flared type of employing Placement is also arranged.FERRULETYPE Placement easy for installation, but thrust load is born in its friction by cutting ferrule and tube wall, it is unreliable to connect, and its neck bush causes the undergauge of pipeline bigger, and the local resistance loss that causes is bigger.The flared type Placement is simple in structure, connects reliably, and undergauge is less, but it needs earlier adpting flange is inserted in composite pipe before enlarging, easily causes the trouble of enlarging flange neglected loading, and construction and transportation are also inconvenient.
The purpose of this utility model be to provide a kind of not only simple in structure, connect reliable, good seal performance, be easy to construction and transportation simultaneously again, mount and dismount more convenient composite metal-plastic pipe pipe fitting.
In order to achieve the above object, the utility model is to adopt following scheme to realize: this composite metal-plastic pipe is made up of major parts such as connecting flange, neck bush, opposite opened conical ring, bolt, seal rings with pipe fitting.The two composite pipe end special tool enlargings that earlier desire connected during installation are set to two connecting flanges respectively two pipe ends after the enlarging then; An end that installs the Steel Lining of seal ring is inserted the flared end of a composite pipe, again the flared end of another composite pipe is installed to the other end of Steel Lining; The opposite opened conical ring is respectively charged in the flange taper hole, then flange is shifted to flared end the conical ring inwall is matched with the composite pipe male cone (strobilus masculinus), promptly finish connection with bolton two flanges.
After adopting said structure, because connecting flange has adopted big internal taper hole formula design, the locking conical ring adopts opposite opened, need not be inserted in flange in advance before the enlarging, forgets the trouble that presets flange in the time of can avoiding enlarging; The neck bush good seal performance of band seal ring, and can bear higher radial force and axial force; All parts adopt nonpoisonous anti-corrosive paint or other anti-corrosion measure, and overall corrosion resistance can be extremely strong; Each Element Design meets the concerned countries standard, makes pipeline connection process simple and convenient, very flexible, and is easy to be connected with other standard pipe accessory.Overcome traditional composite pipe with the fitting structure complexity, trouble, cost height are installed, bear axial force little, many shortcomings such as can not be connected with other type fitting to fitting, its combination property is very superior.Simple in structure, the convenient and flexible installation of the utility model, connect reliable, with low cost, pipe fitting kind demand is few, and can be connected easily with other standard pipe fitting, be a kind of composite metal-plastic pipe pipe fitting easy to utilize.
Be further described below in conjunction with drawings and Examples.
As shown in Figure 1, composite metal-plastic pipe of the present utility model is made up of major parts such as connecting flange 1, opposite opened conical ring 2, neck bush 3, bolt 4, seal rings 5 with pipe fitting, the minimum diameter of the internal taper hole of connecting flange 1 also can install it greater than the maximum outside diameter of composite pipe pipe end enlarging place easily after the composite pipe enlarging; Conical ring 3 adopts opposite opened, makes it both easy for installation, can effectively transmit locking again and seal needed radial force and axial force; Neck bush 2 can bear higher radial force and axial force, and seal ring 5, favorable sealing property are equipped with in its outside.
The utility model pipe fitting major part adopts made such as steel, cast steel, and carries out nonpoisonous anti-corrosive paint spraying or surface treatments such as chromium plating, nickel plating, and pipe fitting has good heat-resisting, decay resistance.Can be widely used in the connection of pipelines such as oil, chemical industry, rock gas, town water supply, air feed, heating.
Claims (3)
1. composite metal-plastic pipe pipe fitting is characterized in that pipe fitting is made up of parts such as connecting flange 1, opposite opened conical ring 2, neck bush 3, attachment bolt 4 and seal rings 5.
2. pipe fitting according to claim 1 is characterized in that the maximum outside diameter of the minimum diameter of connecting flange internal taper hole greater than enlarging place of composite pipe pipe end, and it can be installed after the composite pipe enlarging easily.
3. pipe fitting according to claim 1 is characterized in that conical ring adopts to split pattern (Hough formula), by this conical ring transmission locking with seal needed radial force and axial force.
