德国洛克供应优质进口电动单座笼式调节阀

一、进口电动单座笼式调节阀描述：

德国《LOCKE》洛克进口电动单座笼式调节阀适用于高压差易产生闪蒸空化的场合，是一种高性能的单座调节阀，坚固的套筒保护阀体不受闪蒸和空化的破坏。该阀结构紧凑，有呈 S流线型的通道，使其压降损失小，流量大，可调范围广。阀芯导向面积大，抗振性好。

German "locke" imported electric single seat cage type control valve is suitable for high pressure difference prone to flash cavitation occasion, is a high performance single seat control valve, solid sleeve to protect the valve body from flash and cavitation damage. The structure of the valve is compact, with s-streamline channel, so that the pressure drop loss is small, the flow rate is large, and the adjustable range is wide. The valve core has large guiding area and good vibration resistance.

二、进口电动单座笼式调节阀结构特征：

●顶式双导向单座阀，结构紧凑，动作灵敏部件少，易维护；

●粗壮的阀杆及其一体的阀芯，能承受高负载而阀芯不至脱落；

●自对中卡入式的阀座易于拆出，而且不需要研磨，就可以达到严密的关断密封。

●阀体按流体力学原理设计成等截面低流阻流道，压降损失小，容量大，额定流量与系统增大30%。

●阀芯和阀座固定笼设计有标准型和严酷工况型（消除气蚀式，降噪式等），具有更长的使用寿命，更高的抗气蚀和降噪音性能，只需更换阀座固定笼就可适用于不同工况的需要。

●阀门的关闭是借助于流体压力、弹簧反作用力和气缸推力，具有抵抗非常高的流体压差的关断推力，使阀门关闭的更加严密。

●双导向、双重密封结构，减少了填料外漏的可能。

●该系列调节阀可以流开安装，也可以流关安装。

Top type double guide single seat valve with compact structure, sensitive action, few parts and easy maintenance;

The robust valve stem and its integrated valve core can bear high load without falling off the valve core;

The self centering and snap in valve seat is easy to remove, and can achieve tight shut-off seal without grinding.

The valve body is designed as equal cross-section low flow resistance channel according to the principle of fluid mechanics, with small pressure drop loss, large capacity and 30% increase of rated flow and system.

The valve core and seat cage are designed with standard and severe working conditions (cavitation elimination type, noise reduction type, etc.), which have longer service life, higher cavitation resistance and noise reduction performance, and can be applied to different working conditions only by replacing the valve seat cage.

The valve is closed with the help of fluid pressure, spring reaction force and cylinder thrust, which can resist very high fluid pressure difference and make the valve close more tightly.

Double guiding and double sealing structure reduces the possibility of packing leakage.

The series of regulating valves can be installed either by flow opening or by flow closing.

三、进口电动单座笼式调节阀结构特点：

1、可调节范围大，固有可调比为50，流量特性有直线和等百分比。

2、调节切断型采用软密封结构阀芯，达VI级泄漏标准(零泄漏)。

3、伺服放大器采用深度动态负反馈，可提高自动调节精度。

4、电动操作器有多种形式，可适用于4~20mA。DC或0~10mA.DC。

5、波纹管密封型调节阀对移动的阀杆形成完全的密封，堵绝流体外漏。

6、电子型电动调节阀可直接由电流信号控制阀门开度，无需伺服放大器

1. The adjustable range is large, the inherent adjustable ratio is 50, and the flow characteristics have straight line and equal percentage.

2. The regulating cut-off valve core adopts soft sealing structure, reaching the VI level leakage standard (zero leakage).

3. The servo amplifier adopts deep dynamic negative feedback, which can improve the automatic adjustment accuracy.

4. There are many kinds of electric operators, which can be applied to 4 ~ 20mA. DC or 0 ~ 10 mA.DC 。

5. The bellows seal type control valve forms a complete seal to the moving valve stem and blocks the fluid leakage.

6. Electronic electric control valve can control valve opening directly by current signal without servo amplifier
