筒式換向閥

筒式換向閥，普遍用於建材、冶金、礦山、石化、電力等行業。能承受沖擊大、磨損性大的礦石、礦渣、塊煤、焦炭、灰渣等塊狀、粒狀、粉狀物料的沖刷，而且能在物料通過時換向。

The valve is widely used in building material, metallurgy, mining, oil chemical and electric power industries. It can bear the scour of the block, granular and powder material such as ore, cinder, clod coal, coke, and ash residue etc. It can change the direction when material passes.

結構特點:

Structure characteristic:

筒式換向閥采用封閉式內套筒旋轉換向，可以使物料流與本體分離，其結構完善、科學，方位指示明確，換向快捷、靈活、可靠，不會存在卡料、漏料、積料、結疤等現象，是輸送系統中物料換向的理想設備。配以不同的傳動裝置以滿足不同的工況需要。

S為手動式，D為電動式，Q為氣動式，Y為電液動式；Ⅰ型為側三通筒式換向閥，Ⅱ型為正三通筒式換向閥。

The structure of the valve is sealed in sleeve cylinder rotating alternating direction structure, which can separate the material and body. It has the features of fine and science structure, definite indicating direction, quick and reliable in alternate direction and there are no conditions of leakage, obstruction and piling. It can meet different working conditions demand equipped with different transmission devices, which is the ideal equipment to change direction of material in transportation system.

S denotes manual, D denotes electric, Q denotes pneumatic and Y denotes electric hydraulic; typeⅠis side three-way cylinder reversal valve and typeⅡis face three-way cylinder reversal valve.

工作原理：

Working principle:

筒式換向閥主要由本體、套筒、傳動軸、搖桿、傳動裝置等組成。物料由進料口入，通過套筒導向，使物料到達指定出口。

手動筒式換向閥根據需要的方向人工推動手柄，帶動傳動軸及套筒換向，即完成介質流向的切換，滿足工況的需要。電動筒式換向閥配用DT型電動推桿，推桿受控通電後，推動搖桿轉動閥軸即可完成介質流向的切換。電液動筒式換向閥配用DYT型電液動推桿，推桿受控通電後，帶動閥軸、套筒換向，即可完成介質的切換。氣動筒式換向閥配用10A-5型氣動推桿，通過雙控二位五通電控換向閥驅動氣動推桿動作，推動搖桿帶動閥軸、套筒動作，即完成流向切換，所有換向切點都有信號反饋。以顯示工作方位。

The valve is mainly made up of body, sleeve pipe, transmission shaft, rocker and transmission device etc. Material gets into the feeding intake and reaches the indicated outlet after guarded by sleeve cylinder.

Pull the handle of manual valve that drives the transmission shaft and sleeve pipe changing direction and then the medium flow direction is switched. The electric valve is equipped with type DT electric draw stem. When the draw stem is powered, it will pull rocker to rotate valve axle and the medium flow direction is switched. The electric hydraulic valve is equipped with type DYT electric hydraulic draw stem. When the stem is powered, it will drive valve axle and sleeve pipe switching and the medium flow direction is switched. The pneumatic valve is equipped with type 10A-5 pneumatic draw stem. The double-control two-bite five-way electric control reversal valve drives the pneumatic draw stem and pulls rocker move with valve axle and sleeve pipe and the medium flow direction is switched. There is signal feedback of all alternating directionpoint of contact, which can indicate the working position.
