Description

Technical Field

[0001] The present invention relates to the field of optical fibers, and more particularly to an opening and closing valve for optical fiber ointment coating. Background Art

[0002] During the long-term use of optical cables, the infiltration of moisture and humidity will lead to the deterioration of the transmission performance of the optical cables and even render them unusable. In order to prevent the intrusion of moisture and to prevent the optical fibers from being damaged due to mutual friction during the manufacture of optical cables, it is necessary to fill the voids in the optical cables with optical cable ointment and to coat the optical fibers with optical fiber ointment to ensure good mechanical properties of the optical fibers and to extend their service life.

[0003] Chinese Patent CN106226875A discloses an optical cable ointment spraying device. In this device, an ordinary ball valve is used to control the opening or closing of the device. This spraying device is adapted to the spraying of an optical cable metal strip, but it cannot achieve the conversion of spraying multiple metal strips, so that a new metal strip can be replaced after the ointment coating of this strip is completed. At the same time, since the pipeline transports ointment, after the ball valve is used for a period of time, a large amount of oil dirt is likely to deposit at this place, resulting in unstable pressure at this place and affecting the coating effect.

A sealing arc block 623 is provided on the lower plate. Correspondingly, a flushing box is provided on the lower side of the connecting pipe. The flushing box includes a left plate 63. The left plate is connected to a first plate 64. The first plate is connected to an inclined plate 65. The inclined plate is connected to a bottom plate 66. The bottom plate is connected to a right plate 67. The right plate is communicated with a water pipe 68. A threaded guiding hole 631 is provided on the left plate. A semi-circular sealing groove 632 that cooperates with the sealing arc block is provided at one end of the threaded guiding hole close to the rotating sealing plate. A first threaded hole is provided on the first plate. A tensioning bolt 69 is threadedly connected to the first threaded hole. A steel wire rope 610 is connected to the tensioning bolt. The other end of the steel wire rope is fixedly connected to the rotating sealing plate. A threaded push rod 611 is mounted in the threaded guiding hole.

[0026] In a refined solution, a fixed central hole 11 is provided in the middle of the fixed disk. A rotating shaft 4 is mounted in the fixed central hole.
