進(jìn)口電動(dòng)籠式單座調(diào)節(jié)閥德國(guó)洛克

一、進(jìn)口電動(dòng)籠式單座調(diào)節(jié)閥描述：

德國(guó)《LOCKE》洛克進(jìn)口電動(dòng)籠式單座調(diào)節(jié)閥，采用頂部導(dǎo)向不平衡式結(jié)構(gòu)，高強(qiáng)度、重載荷、S型流道、壓降損失小、流量系數(shù)大、可調(diào)范圍廣、流量特性精度高。該類型調(diào)節(jié)閥適用于工況允許壓差小、閥前后壓差較大的工作場(chǎng)合，關(guān)閉嚴(yán)密，適用于對(duì)介質(zhì)流量或者壓力的調(diào)節(jié)。本系列產(chǎn)品有常溫型、高溫型、低溫型、調(diào)節(jié)切斷型、波紋管密封型等多種型式。

The electric cage type single seat regulating valve imported from Germany "locke" adopts top guiding unbalanced structure, with high strength, heavy load, S-type flow channel, small pressure drop loss, large flow coefficient, wide adjustable range and high flow characteristic precision. This type of control valve is suitable for working conditions with small allowable pressure difference and large pressure difference before and after the valve. It is tightly closed and suitable for regulating medium flow or pressure. This series of products have room temperature type, high temperature type, low temperature type, adjustment cut-off type, bellows seal type and other types.

二、進(jìn)口電動(dòng)籠式單座調(diào)節(jié)閥結(jié)構(gòu)特點(diǎn)： 

1、可調(diào)節(jié)范圍大，固有可調(diào)比為50，流量特性有直線和等百分比。

2、調(diào)節(jié)切斷型采用軟密封結(jié)構(gòu)閥芯，達(dá)VI級(jí)泄漏標(biāo)準(zhǔn)(零泄漏)。

3、伺服放大器采用深度動(dòng)態(tài)負(fù)反饋，可提高自動(dòng)調(diào)節(jié)精度。

4、電動(dòng)操作器有多種形式，可適用于4~20mA。DC或0~10mA.DC。

5、波紋管密封型調(diào)節(jié)閥對(duì)移動(dòng)的閥桿形成完全的密封，堵絕流體外漏。

6、電子型電動(dòng)調(diào)節(jié)閥可直接由電流信號(hào)控制閥門開度，無需伺服放大器 。

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. The electronic electric control valve can directly control the valve opening by the current signal without servo amplifier.
