Scope of application and structure characteristics of pneumatic valve throttle

throttling of the pneumatic valve is introduced:
pneumatic valve, throttle is to point to by changing the channel area to control or adjust the medium flow rate and pressure of the pneumatic valve. Pneumatic valve throttle is mostly used for throttling in the pipeline.
, the most common throttling pneumatic valve is used as pneumatic valve for throttling after pneumatic disc to change shape. But with change by pneumatic valve or gate valve opening for throttling with is highly appropriate, in the condition of throttle velocity is very high, because the media will inevitably make the sealing surface erosion wear, lose to cut off the sealing function. Same with pneumatic valve throttle cutting device is inappropriate.

throttling pneumatic valve of the scope of application:
throttling pneumatic valve according to the passage ways can be divided into straight-through and Angle type two kinds; According to the shape of the open-close part points, have needle, ditch and window 3 kinds. Hook pneumatic disc, often used in the cryogenic device in expansion pneumatic valve. Window type pneumatic disc, is suitable for large diameter throttle pneumatic valve. Plug type pneumatic disc, applicable to small and medium caliber pneumatic valve, throttle is used more widely.

throttling the structure characteristics of pneumatic valve:
, structure is simple, easy to manufacture and maintenance, the cost is low.
and regulating accuracy is not high, cannot be used to adjust.
and sealing surface erosion, cannot be cut off the medium used.
poor, sealing.
