[0002] Valves are used to open and close pipelines, control flow direction, adjust and control parameters of delivered medium, and are divided into shut-off valves, check valves, regulating valves and the like according to their functions. Valves are control components in fluid delivery systems, and have functions such as shut-off, regulation, flow direction, anti-backflow, pressure stabilization, shunt or overflow pressure relief, etc. Valves used in fluid control systems are quite diverse in terms of variety and specifications, ranging from the simplest shut-off valve to the most complex self-control system. Valves are usually connected with pipelines, and in some large pipelines, optical cables are laid to transmit signals inside the pipeline. At the valve position of the pipeline, the laid optical cable usually needs to bypass the valve.

[0003] However, the valve structure currently used on the pipeline needs to bypass the valve when laying the cable, which not only causes the cable laying to be cumbersome, but also causes the sealing performance of the pipeline to decrease. SUMMARY

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1.

Under the normal operating state of the valve, the installation of optical cables can be realized, so that when the optical cables laid in the pipeline encounter the valve, they do not need to pass through and detour, making the wiring more convenient, the optical cables safer, and the overall operation smoother.

[0032] 2. By setting threaded rings, sealing rings, mounting rings, connecting blocks, connecting flanges, fixing blocks, connecting rods, snap-fit ​​discs, fastening nuts, sealing gaskets, mounting holes, and sealing plates, after valve installation, the connecting rod passes through the connecting blocks and fixing blocks, making the connection pipes at both ends of the valve body more tightly connected and less prone to loosening during valve use. By setting sealing rings at both ends of the valve body, snapping sealing gaskets at the connecting flange positions, and setting sealing plates, the sealing performance at the connection positions is increased, improving the overall sealing effect of the valve.

[0033] In summary, by setting through holes and wire holes for optical cables to pass through, the optical fiber can be laid inside the pipe and can pass directly through valves without having to go out of the pipe to avoid the valves during installation. This makes the installation of optical cables more convenient and faster. Furthermore, by setting sealing rings and gaskets at the connection points and using connecting rods in conjunction with fixing blocks and connecting blocks for secure connection, the sealing performance at the valve locations is enhanced.

7. A valve structure with a wire passage hole according to claim 5, characterized in that, One end of the connecting rod (709) is engaged with the connecting hole (705) in the middle of the connecting block (704).

8. A valve structure with a wire passage hole according to claim 5, characterized in that, The sealing plate (714) is snapped into the inner side of the mounting hole (713) in the middle of the connecting flange (706), and the inner diameter of the sealing plate (714) is half the inner diameter of the mounting hole (713) in the middle of the sealing gasket (712).

9. A method for producing a valve structure with a wire passage hole according to claim 1, characterized in that, The production process includes the following steps: S1. First, make molds for the valve body (1), the first connecting end pipe (2), the second connecting end pipe (3), the valve stem (4), and the ball (5); S2. The molten steel in the mold is poured into a film and then demolded to obtain the valve body (1), the first connecting end pipe (2), the second connecting end pipe (3), the valve stem (4), and the ball (5). S3. First, snap the ball (5) into the valve body (1), and then snap the valve stem (4) into the top of the valve body (1) to connect with the ball (5); S4. Then, the two open mounting rings (703) are respectively fitted onto the outside of the first connecting end tube (2) and the second connecting end tube (3), and the opening positions are welded. S5. Fit the sealing ring (702) onto the outside of the first connecting end tube (2) and the second connecting end tube (3), and fix it to the mounting ring (703); S6. Grind the ring into a valve seat (601) and make holes in the middle of the valve seat (601), the first connecting end tube (2) and the second connecting end tube (3); S7. Snap the valve seat (601) onto both ends of the valve body (1), and then screw the first connecting end tube (2) and the second connecting end tube (3) onto both ends of the valve body (1) so that the openings of the valve seat (601), the first connecting end tube (2) and the second connecting end tube (3) are aligned. S8. Then, the optical cable (603) is passed through the valve seat (601), the first connecting tube (2), and the second connecting tube (3) through the middle hole to complete the initial installation. S9. Then, attach the first sealing plate (608) and the second sealing plate (609) to the outside of the optical cable (603), and then insert the fixed half tube (610) into the opening position of the first connecting end tube (2) and the second connecting end tube (3).
