Description
Technical Field
The utility model relates to a choke valve technical field, concretely relates to choke valve with adjustable it is manual.
Background
The shape of the throttle valve is not different from that of the shut-off valve, except for the shape of the opening and closing member. The open-close member of the throttle valve is mostly in a conical streamline shape, and the flow and the pressure can be adjusted by changing the sectional area of a channel. The throttle valve serves to reduce the pressure of the medium in the event of a very large pressure drop.
The flow rate of the medium between the throttle flap and the valve seat is so great that the surfaces of these parts are damaged very quickly, the so-called cavitation phenomenon. In order to minimize the cavitation effect, the flap is made of a cavitation-resistant material (alloy steel) and is made as a streamlined cone with a tip angle of 140 to 180. This also enables a large opening height of the flap, which is generally not recommended for throttling at small gaps.
