流量控制阀

FLOW CONTROL VALVE AND FLOW ROTARY VALVE

流量控制阀用作控制库底卸出的物料量，通常与气动开关阀一起使用。物料先通过一段小斜槽，使物料流态化，然后再进入流量阀，这样可避免在流量控制部分形成料柱。流量控制阀由电动执行器调节开度，可实现远距离控制阀门的开度，以满足系统计量的要求。气动开关阀主要在物料流量控制系统中作开关用，通常与电动流量控制阀串联配套使用。广泛适用于建材、冶金、化工、粮食、玻璃等行业。

This valve is used with the rotary valve to control the material discharged from the bottom of storehouse. The material was change to liquid material after pass through a chute and then flow into the flow valve, which can prevent the flow control parts from forming columnar material. The open angle of the flow control valve is adjusted by electric actuator, which can be controlled remotely to meet the requirement of system measure. The rotary valve is used to be switch in material flow control system, which is equipped with electric flow control valve tandem. They are widely used in building material, metallurgy, chemical, food and glass industries etc.

Structure characteristic:

流量控制阀和气动开关阀设计科学合理、结构紧凑、阀芯开有 U型槽口，调节槽口开度可进行流量控制，指示盘可指示阀芯开度，阀芯与电动执行机构的联轴器增设安全销，保证阀芯和执行机构不受损坏，在阀的进口设有衬垫，将阀体与阀芯隔开，衬垫与阀芯之间径向间隙可调整，以保证阀芯运转的灵活性。流量控制阀配用电动执行器。回转阀配用气动推杆。

The valves are scientific and reasonable in design, compact structure. There is a U-form notch on the valve cartridge. Control the flow when adjust the open angle of notch. The open angle of valve cartridge can be displayed on indicating plate. The shear pin is added to the shaft coupling of valve cartridge and electric actuator, which avoids the damage of valve cartridge and actuator. There is cushion on the intake of valve that separates the body and valve cartridge. The radial gap between cushion and valve cartridge is adjustable to ensure the flexibility of valve cartridge rotation. The flow control valve is equipped with type DKJ actuator and the rotary valve is equipped with type 10-5A pneumatic draw stem.

Working principle

流量控制阀主要有机座、阀体、密封垫、衬套、阀芯、轴承、透气层、充气槽及传动装置组成。风机给予低压小容量空气，经通道口由充气槽充气，气体透过透气层，均匀向上喷吹，鼓动物料向上位移，物料自重下落时，由设备安装斜度而产生位移，不断重复致使物料向前位移。执行机构带动联轴器，阀芯动作，以调节物料流量。回转阀只作开关作用，通过电磁阀控制气动推杆气源来指令推杆动作，完成切换动作。

The flow control valve is mainly made up of housing, body, sealing shim, liner bushing, valve cartridge, bearing, breather layer, aerator tank and transmission device etc. The low pressure little volume air supplied by wind machine is aerated from aerator tank through tunnel intake. Then the gas blows upwards through breather layer to drive the material move upwards. Because of the installation incline, material will fall in the effect of gravity. The unceasing repeating actions make the material move forwards. The actuator drives the shaft coupling and valve cartridge to adjust the material flow. The rotary valve is used to be switch. The electromagnetism valve controls the gas source of pneumatic draw stem and drives the draw stem to switch the valve.

使用说明

Usage explanation

• 安装前请检查内腔有无杂物附着 ， 否则会堵塞 U 型阀芯或损坏阀件。查看沸腾板受潮没有，如沸腾板受潮请更换后再进行安装，否则影响使用效果。检查各传动部分是否灵活可靠。

• 安装时传动部分不允许作吊装用，并严禁损伤。两法兰连接中间需加密封垫片，然后均匀拧紧联接螺栓。

• Check the valve if there is lumber inside the body, which will block the valve cartridge or damage the parts. Check the boiling disc. Exchange the boiling disc before install if it is damp. Otherwise it will affect the operation. Check the transmission part.

• The transmission part cannot be hoisted and damaged. Add sealed shim between the two flanges and then lock down the bolt equably.
