Usage and Product Overview: F343X-1.5 TypeManual turbine blind valveIn accordance with the provisions of GB622-86 "Safety Regulations for Industrial Enterprise Gas", it is a reliable safety device that can cut off the medium in the pipeline system when the valve is in the closed state. This valve is widely used in dust removal and environmental protection facilities for pipeline systems such as gas, flue gas, dusty gas, and air in the metallurgical industry.

F343X-1.5 typeManual fan-shaped blind valveIt can quickly open and close, reliably cut off gas media, and is an ideal safety control valve for cutting off gas and gas pipelines.

Structure description: F343X-1.5 typeHandwheel type fan-shaped blind plate valveThe external structure of the valve is shown in the figure. It consists of a left valve body, a middle valve body, a right valve body, a fan-shaped blind plate, a screw nut pair, a lever, a stainless steel compensator, two worm gear transmission boxes, etc. It is connected by three screw rods and fixed on the base to form a rigid structure. The middle valve body and the right valve body are connected by stainless steel expansion tubes, and the left and middle valve bodies are respectively connected by three lead screws with trapezoidal threads on both ends. By rotating the three lead screws in the forward (or reverse) direction at the same time, the left and middle valve bodies are compressed (or separated). One of the three lead screws is equipped with a blind plate in the middle, which rotates around the axis. The two lead screws below are equipped with blind plate positioning blocks at the same location. When the blind plate rotates, it can prevent the blind plate from drifting and avoid scratching the sealing rubber ring. One of them is equipped with a worm gear transmission box to loosen and clamp the valve body.
