進口電動薄膜三通調節(jié)閥的分類及選型依據(jù)德國洛克 

一、進口電動薄膜三通調節(jié)閥描述：

德國《LOCKE》洛克進口電動薄膜三通調節(jié)閥，是由PSL系列和LOCKE系列直行程電動執(zhí)行機構和三通調節(jié)閥體組成。(也可配其它品牌直行程執(zhí)行機構)。電動執(zhí)行機構為電子式一體化結構，內有伺服放大器，輸入控制信號(4-20mADC或1-5VDC)及電源即可控制閥門開度，達到對壓力、流量、液位、溫度等工參數(shù)的調節(jié)。電動薄膜三通調節(jié)閥具有動作靈敏、連線簡單、流量大、體積小、調節(jié)精度高等特點。控制精度和性能比LDKZ型有明顯提高。電動薄膜三通調節(jié)閥具有調節(jié)精度高，動作穩(wěn)定可靠等優(yōu)點。

Germany "locke" imported electric thin film three-way control valve is composed of PSL series and locke series straight stroke electric actuator and three-way regulating valve body. (it can also be equipped with other brands of straight stroke actuator). The electric actuator is an electronic integrated structure with servo amplifier. The valve opening can be controlled by inputting control signal (4-20madc or 1-5vdc) and power supply, so as to adjust working parameters such as pressure, flow, liquid level and temperature. The electric film three-way control valve has the characteristics of sensitive action, simple connection, large flow, small volume and high regulation accuracy. The control precision and performance of ldkz are obviously improved. The electric film three-way regulating valve has the advantages of high regulation precision, stable and reliable action.

三、進口電動薄膜三通調節(jié)閥結構特點:

流體對閥芯作用方向都處于流開狀態(tài)，故工作穩(wěn)定性好。除了閥蓋處襯套導向外，閥芯側面與閥座內表面也有導向作用，導向面積大，工作可靠。伺服放大器采用深度動態(tài)負反饋，可提高調節(jié)精度。

電動操作器有多種形式，可適用于4～20mA.DC或0～10mA.DC。電子型電動調節(jié)閥可直接由電流信號控制閥門開度，無需伺服放大器。

節(jié)省自動化投資，與單座、雙座或套筒調節(jié)閥相比，組成同樣的系統(tǒng)可省掉一個閥，簡化系統(tǒng)，節(jié)省投資。

波紋管密封型對移動的閥桿形成完全的密封，堵絕流體外漏。

The action direction of the fluid to the valve core is in the flow open state, so the working stability is good. In addition to the guide of the bushing at the valve cover, the side of the valve core and the inner surface of the valve seat also have the guiding function, with large guiding area and reliable operation. The servo amplifier adopts deep dynamic negative feedback, which can improve the adjustment accuracy.

There are many kinds of electric operators, which can be used in 4 ~ 20 mA.DC Or 0-10 mA.DC 。 The electronic electric control valve can directly control the valve opening by the current signal without servo amplifier.

Compared with single seat, double seat or sleeve control valve, the same system can save one valve, simplify the system and save investment.

The bellows seal type forms a complete seal on the moving valve stem and blocks the leakage of fluid.
