Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing, but is not limited thereto.
The specific embodiment of optical cable infiltration test device provided by the invention, as shown in Figure 1 to Figure 3, optical cable infiltration examination
Experiment device includes water storage container, and water storage container includes lateral tube body 1 and the vertical tube body that is connected to lateral tube body 1, in this implementation
In example, vertical tube body is the lucite tube 2 with level scale, indicates the level scale of 1 meter of height thereon, in this way can be straight
Watch whether water level reaches 1 meter of requirement.Lucite tube 2 is constituted in the setting of the middle section of lateral tube body 1 and with lateral tube body 1
Inverse-T-shaped, the connectivity part of lucite tube 2 and lateral tube body 1 is sealed using O-ring seal 11.Lateral tube body 1 is using stainless
The seamless steel pipe of steel material, the tube head sealing at both ends, lateral tube body 1 offer water tank at the position close to lucite tube 2
Interface 10.The surface of vertical direction of the lateral tube body 1 in lucite tube 2 offers spaced apart outlet pipe 3, every group of water outlet
Pipe 3 is connected in outlet valve 4(attached drawing arranged up and down by three-way connection and only shows an outlet valve, is in practice upper and lower
Two outlet valves of arrangement), the water outlet 5 of each outlet valve 4 is connected with fiber cable joint 6.
Fiber cable joint 6 is the structure of cylindrical body, whole to be made of plastic cement material, and one end of fiber cable joint 6, which is equipped with, to be used for
The through-hole 7 of optical cable to be measured is penetrated, the internal screw thread with the sealing cooperation of the water outlet 5 of outlet valve 4 is equipped in through-hole 7, is also set in through-hole 7
There is the block step with the gasket seal 8 of optical cable to be measured sealing cooperation and with the cooperation of 8 block of gasket seal.Fiber cable joint 6 with
When outlet valve 4 connects, the water outlet 5 of outlet valve 4 presses gasket seal 8 and arrives block step.Gasket seal 8 uses rubber material system
At, which is provided with for optical cable to be measured be inserted into and with optical cable outer peripheral surface to be measured sealing cooperation sealing hole 9, the aperture of the sealing hole 9
