Abstract
The invention relates to a connecting method for plastic composite pipes of a steel wire mesh framework and a connecting element used in the connecting method. Movable joint connecting elements are respectively welded on two metal buckle pressing sleeves in advance, then, the metal buckle pressing sleeves are respectively buckled and pressed on the outer diameter surface of the end part of two sections of plastic composite pipes of the steel wire mesh framework through buckle pressing equipment, and the two sections of plastic composite pipes of the steel wire mesh framework are connected through the movable joint connecting elements. The connecting method and the connecting element have the beneficial effects that the structure is simple, the connection is safe and reliable, the connection operation is convenient and fast, the occupied space of the appearance of the connecting part is small after the pipe connection, the connection performance requirement of the plastic composite pipes of the steel wire mesh framework at the 7.0Mpa pressure is completely met, and the installation operation in the narrow work space in mine and the like is convenient.
Description
Affiliated technical field
The present invention relates to plastic tube, be specially a kind of steel wire mesh frame plastic composite tube connecting means and employed link thereof, be particularly useful for mine with the connection of 7Mpa with the downforce steel wire frame plastic composite pipe.
Background technique
At present, known steel wire mesh frame plastic composite tube connecting means is that electric smelting directly saves methods such as connection and the connection of electric smelting plastics flange.Utilize iron flange, bolt and nut etc. that pipeline is linked together.
Summary of the invention
In order to satisfy the connection request of the following pressure piping of steel wire mesh frame plastic composite tube 7Mpa; The present invention provides and adopts the connecting means that is threaded; The connection request that meets the operation steady in a long-term of the following pressure piping of steel wire mesh frame plastic composite tube 7Mpa; Join strength is high, is easy to processing, is convenient to fitting operation in the inferior narrow working space of mine simultaneously.
The technological scheme that technical solution problem of the present invention is adopted is: a kind of steel wire mesh frame plastic composite tube connecting means; It is characterized in that in advance the movable joint link being welded on respectively on two metal button gland pipes; Utilize the equipment of withholding that metal button gland pipe is withheld respectively on the outer end diameter face of two joint steel wire mesh frame plastic composite tubes again, two joint steel wire mesh frame plastic composite tubes are linked together through described movable joint link.
The movable joint link that is adopted is a screw thread movable joint link, that is: an end connection is metal button gland pipe and the movable joint head that welds its end, is with the kink of band internal thread on this movable joint head; The other end link is metal button gland pipe and the screw thread silk head that is welded on its end; Said kink and screw thread silk are corresponding; Be respectively equipped with corresponding groove on the interface of said movable joint head and screw thread silk head, seal ring is arranged in the groove.
Described seal ring is an O type circle.
Described kink periphery is a cylindrical shape, the pit that on its outer wall, has at least one to supply fastening this kink to use.
On the described metal button gland bore face anti-back groove is arranged.
The invention has the beneficial effects as follows; Simple in structure, attachment security is reliable, and attended operation is convenient and swift; After tubing connects; The connection part profile takes up room little, meets the switching performance requirement in the steel wire mesh frame plastic composite tube road of 7.0Mpa pressure fully, is convenient to fitting operation in the inferior narrow working space of mine.
