Definitions

  • the invention relates to a pipe connecting member, in particular to a simple processing, convenient and quick installation, capable of meeting the expansion and contraction deformation of the pipe due to temperature change, not destroying the surface of the pipe body, reducing the cost of the pipe connection, and meeting the anti-corrosion requirements.
  • Double cone ring for tube fittings Double cone ring for tube fittings.
  • the flexible rubber sealing ring connected thereto is deformed and expanded from the opening of the locking ring, and it is necessary to add a pad between the tapered locking ring and the sealing ring.
  • the film not only has troublesome processing, but also increases the cost of pipe connection.
  • Chinese patent application number is 200410020582.6
  • the sealing function is realized by using a conical sealing ring.
  • the locking connection function is to use a snap ring, and a gasket is also added between the sealing ring and the snap ring. After the three components are installed, the connection can be made, the pipe installation is still troublesome, and the manufacturing cost is also high.
  • the invention patent discloses a 'wedge taper block combination locking pipe connecting method' in which a 'flange locking connection method' is used.
  • This connection method The tapered inner bore of the locking flange is pressed against the tapered oblique back of the wedge-shaped tooth block, and the wedge-shaped tooth block is pressed, and the teeth on the inner side of the wedge-shaped tooth block are tightly bitten.
  • the locking flange is such that the connecting tube is locked by the wedge-shaped tooth block to realize the connection between the tube and the tube.
  • Several wedge-cone shaped blocks are embedded in a conical block holder.
  • the hard teeth on the inside of the wedge-cone block can bite into the outer skin of the tube. Micron deep, although the locking connection of the pipe is strengthened, it destroys the anti-corrosion protection layer of the pipe surface and reduces the service life of the pipe; the addition of a block bracket also increases the connection cost, and the installation is still three parts: Seal ring, block bracket, and block are still more troublesome to install.
  • the invention is to solve the above technical problems existing in the prior art, and provides a simple processing, convenient and quick installation, can meet the expansion and contraction deformation of the pipeline due to temperature change, does not damage the surface of the pipe body, can reduce the cost of the pipe connection, and satisfies
  • a double cone ring is used for the joint pipe fittings required for corrosion protection.
  • the technical solution of the present invention is: a double cone ring for a joint pipe fitting, an annular body made of rubber or plastic, which is a cylindrical hole, and an axial middle portion of the outer side of the annular body is cylindrical and axial.
  • the two ends are conical, and have an annular groove having a height equal to that of the cylindrical shape on the outer surface of the cylindrical shape, and a metal hoop having the same size as the annular groove is built in the annular groove.
  • a plurality of circumferentially distributed steel balls are embedded in the conical mid-waist of the one side, and the spacing between the steel balls is 5 ⁇ 80 mm
  • the steel ball is 10 to 50 microns higher than the outer surface of the annular body.
  • the invention is made of a flexible material such as rubber or plastic, and the conical ring body in the middle end of the connection is subjected to the pressing force of the lock nut or the locking flange, and the tapered tapered surface on the rear end will be
  • the horizontal and vertical force components are generated, and the horizontal component force is transmitted through the intermediate cylinder and the metal hoop, and the tapered ring body at the front end can be pushed, and the front tapered ring body is deformed by force and tightly filled with the pipe fittings. Sealing is achieved with the gap between the tubes; the vertical force component allows the rear tapered ring body to tightly wrap the tube for a locking connection. If the temperature changes to cause the tube length to expand and contract, the tube can slide in the tube without affecting the sealing function.
  • the invention changes the sealing and locking function which can be assumed by the three accessories of the sealing ring, the gasket, the locking ring (or the snap ring, the tooth block and the block bracket) to be completed by one piece, and the construction and installation are simple and not damaged.
  • the surface protective layer of the pipe to be connected can meet the expansion and contraction deformation of the pipe due to temperature changes and reduce the cost of pipe connection.
  • FIG. 1 is a schematic view showing the structure of a first embodiment of the present invention.
  • Fig. 2 is a schematic structural view of Embodiment 2 of the present invention.
  • Embodiment 1 As shown in Fig. 1, in the method of connecting the nut to the nut or the flange to be locked, according to the function of the pipe to be connected Selecting a rubber or an annular body 1 made of a plastic substantially equivalent to the rubber elasticity, the outer side of the annular body 1 is cylindrical in the axial direction 2, and the axial ends are conical 3 in the cylindrical shape 2 The outer surface has an annular groove 4 which is equal in height to the cylindrical shape 2, and a metal hoop 5 having the same size as the annular groove 4 is built in the annular groove 4.
  • Embodiment 2 As shown in Fig. 2, the basic structure is the same as that of the embodiment 1, and the difference from the embodiment 1 is the conical shape on the one side.
  • a plurality of uniformly distributed steel balls 2 are embedded in the middle waist, and the distance between the steel balls 2 is 5 to 80 mm, and the steel balls 2 are 10 to 50 ⁇ m higher than the outer surface of the annular body 1.
  • the outer edge of the steel ball 6 is tangent to the cylindrical inner wall surface of the annular body 1, and the outer edge of the steel ball 6 is 10 to 50 microns higher than the outer surface of the conical mid-waist of the annular body 1.
  • the installation method is the same as the prior art, and the pipe fittings can be locked in various flexible seals: Straight, elbow, tee, cross, reducer, inner joint, outer joint, flange joint, plug and other pipe joints are used together; Due to the flexibility of rubber or plastics that are substantially equivalent to rubber elasticity, it can be adapted to tolerance variations in the outer diameter of pipes of various specifications.
