Conical valve is mainly composed of valve body, diversion cone, sleeve, actuators, tie rod and actuator components, including the body is fixed, actuators move through the drive of opening and closing sleeve, body sealing effect, the valve is in the whole range will not produce cavitation and vibration, still has good flow control effect in traffic hours.

(1) for a fixed inverted conical structure, respectively on the valve body is equipped with metal to metal seat and protective soft sealing seat, or both constitutes the seat to ensure the sealing performance of composite.

(2) good flow conditions, higher flow coefficient than other valves (u=0.75-0.83 or higher)

(3) simple structure, all valve drive parts are set outside the valve body for easy maintenance.

(4) the open-close torque is small, easy to operate, can be applied to without the power of small and medium-sized water conservancy projects, also set up electric, pneumatic, electric hydraulic linkage open-close operation mechanism, easily implement remote control or automatic running unattended.

(5) the discharge when the gushing water tongue as a trumpet-shaped, air diffusion of the fog, the efficiency of the effect is good, simple energy dissipation pool or no energy dissipation measures, such as the setting for the submerged discharge, the underwater of energy dissipation is also very simple

(6) the fluid is evenly divided by 4-8 inner guide vanes to reduce the generation of whirlpool and vibration;

(7) its opening and closing of the valve or flow control by outside around the sleeve movement to opening and closing action, sealing is realized by using square seal between the sleeve and body, between sleeve and the valve guide paper copper bar is fixed on the back blades, move the sleeve valve flow coefficient and have a certain proportion valve stroke.

(8) for different position and pressure of fluid, you can set the metal hard seal and fluorine plastic soft sealing, high strength alloy stainless steel seat design of the composite structure with the characteristics of the metal to metal seal and soft seal;

(9) the divergence Angle can be limited, and the fluid can be decomposed into rarefied spray or circular convection to achieve the purpose of shock cancellation.At the same time, it can meet the needs of different sites. If free diffusion is not allowed on the site, the direction of efflux can be controlled by installing a guide cover or a concrete culvert with steel lining.
