The fixed cone valve can be divided into embedded pipe, cone valve body, sleeve, worm gear reducer screw machine, tie rod and balance beam. So everyone knows what are the advantages of this valve? 1. Good hydraulic conditions, with a higher flow coefficient u=0.75～0.83 or higher than other valves;
2. Simple structure and light weight;
3. Small opening and closing force, light manual operation, suitable for small and medium-sized water conservancy without power supply In engineering sites, if necessary, the user can add a motor connection on the other side of the worm gear box to become an electric operating opening and closing mechanism;
4. When the flow is discharged, the water tongue is horn-shaped, and the air is diffused and aerated, and the energy dissipation effect is good, such as Set to submerged outflow, the underwater energy dissipation is also very simple;
5. The equipment layout is compact, the operation is flexible, and the operation and management is convenient and reliable.
