VQ347F-16C Turbine flange v-shaped ball valve
Summary of the turbine flange v-shaped ball valve
Turbine flange v-shaped ball valve is a special type of valve, its close bond is the ball there open V on the cylinder opening, v-shaped openings with a sharp knife blade, in the process of the ball as rotary cylinder, and the shearing action formed between the seat, the media has a strong cutting force, the ball as v-shaped opening cylinder and valve seat port form fan-shaped area, can change the flow in the process of turning to the cross-sectional area, the formation of medium precision adjustment, it is a kind of Angle of rotation of the regulator, the same as the common ball valve sealing, make it of regulator and switch at the same time two functions, equipped with pneumatic or electric actuators, widely used in industrial process control system.
Turbine flange v-shaped ball valve features:
Monolithic structure: 1, body of wafer and flange v-shaped ball valve body are side mounted to the overall structure, it is not easy to cause deformation and leakage.
2, self-lubricating bearings, up and down the body up and down with self-lubricating bearings, contact with the valve stem area is large, high bearing capacity, small friction coefficient, reduce the valve torque.
3, the seat can be according to the needs of medium and conditions, choose metal hard seal or PTFE soft seal: carbide surfacing metal hard seal seat sealing surface and the ball surface hard chromium plating and spray welding, ion nitriding, such as hardening treatment, make the sealing face longer service life, heat resistance performance improvement;Soft sealing PTFE seats or reinforced PTFE seat sealing performance is good, corrosion resistance, wide adaptation.
4, economic applicability: body weight, stem torque is small, with pneumatic or electric actuator corresponding specification is small, compared with other types of regulating valve, the performance-to-price ratio is high.
5, medium range: because the shear force between the v-shaped opening and valve seat, and in the valve cavity flow smooth and rounded, make the medium is not easy to accumulate in the inner chamber, so it except for the liquid medium, more suitable for system control with fiber and solid medium.
6, small flow precise control: the small special v-shaped opening valve core processing, small CV value precise control can be realized.
Lack of process
1, the surface hard chromium plating: sphere surface hard chromium plating, commonly used ordinary medium hard seal process
2, surface spray welding department too stand alloy: corrosive medium commonly used process
3, surface is sprayed tungsten carbide: solid particulate medium, and long life conditions
4, ion nitriding surface: general solid medium
5, small flow rate of the ball: DN25 requirements accurately adjust flow within normal medium
