Fixed cone pneumatic valve operating characteristics

fixed cone pneumatic valve commonly used in dam, reservoir, application environments, such as a dam or reservoir. Fixed cone pneumatic valve is often in the hydroelectric generating set for road use as emissions of pneumatic valve. In the reservoir of the drainage outlet, delivery the middle of the road or need energy dissipation drainage control many occasions are used. In the fluid flow is big, fast speed, high pressure, effective drainage of energy dissipation is imperative. And any cavitation could damage or shock effect on the pipeline should be eliminated. Fixed cone pneumatic valve of fixed cone and guide vane structure design and compared with the traditional fixed cone design can be eliminated and effective energy dissipation discharge pipeline vibration and the influence of the corrosion damage. The movement of the external stainless steel sleeve by a pneumatic valve gate, which can realize zero leakage of the metal to metal seal. After the brake the sleeve to open, water will turn into bundles of small streams into one large diameter horn radiation out. If want to get the injection area is reduced, can be installed dome to limit the scope of fluid jet.
fixed cone, pneumatic valve, the executing agency mechanical drive, belt, hartz alloy pad of the welded steel body, sleeve lock, rubber seal, hartz alloy pneumatic valve seat, guide vane of dome and optional. Nozzle and fixed cone by radiated blade support and connection. Nozzle and retained for a period of no wall open between vertebral body, sleeve lock placed on the outside of the nozzle, through the sleeve brake the axial movement of change without open section of the length of the tube wall, have the effect of adjustment of pneumatic valve opening. Pneumatic valve outlet can be set up according to the actual working condition of dome, dome but constraints pneumatic valve outlet water flow, can be further avoid cavitation damage and spray range too much damage. Medium-sized taper pipe pneumatic valve generally should add dome, pneumatic valve back-end pipeline from cavitation damage. Discharge type installed at the end of the pipeline, pressure, pressure and water level control, and so on.
