气动方型插板阀安装尺寸以及外形图

产品概述
气动方型插板阀是一种粉料、晶粒料、颗粒料及小块物料的流量或输送量的主要控制设备，广泛应用于矿山、粮食等行业控制流量变化或迅速切断（特殊直径≤50mm）。
气动插板阀结构特点：气动单向平板闸阀采用钢板焊接结构，配重杆自复位机构，结构紧凑，工作平稳。气动插板阀、气动双向平板闸阀该闸门主要由框架、闸板及气缸组成，气源通过电磁换向阀带动气缸，气缸带动闸板作水平方向的往复运动，达到阀门的启闭目的。闸阀结构简单，重量轻，操作灵活，装拆方便，采用优质碳素钢制造，其强度高，性能好，使用寿命长；丝杆及螺母采用了软防罩结构，不受外界粉尘影响。

Product introduction
Square Knife gate valve Screw valve is a kind of primary device for controlling flow or flow rate of powder,grain,partcle,and small piece material.It is widely used for such sectors including mining,grain,etc.For regulating flow or cutting rapidly(special material diameter=50).
Pneumatic flashboard valve structure features: one-way slab gate valve USES the steel plate welding structure, balance weight rod since the reset mechanism, compact structure, smooth work. Pneumatic flashboard valve, pneumatic two-way slab gate the gate is mainly composed of frame, gate and cylinder, air source through the electromagnetic directional valve drive cylinder, cylinder drives the ram for the reciprocating movement of the horizontal direction, the purpose of opening and closing of the valve. Gate valve has simple structure, light weight, flexible operation, convenient installation, high quality carbon steel manufacturing, its high strength, good performance, long service life; Screw and nut used the soft proof cover structure, is not affected by the dust.
