德國洛克供應(yīng)優(yōu)質(zhì)進(jìn)口電動單座籠式調(diào)節(jié)閥

一、進(jìn)口電動單座籠式調(diào)節(jié)閥描述：

德國《LOCKE》洛克進(jìn)口電動單座籠式調(diào)節(jié)閥適用于高壓差易產(chǎn)生閃蒸空化的場合，是一種高性能的單座調(diào)節(jié)閥，堅(jiān)固的套筒保護(hù)閥體不受閃蒸和空化的破壞。該閥結(jié)構(gòu)緊湊，有呈 S流線型的通道，使其壓降損失小，流量大，可調(diào)范圍廣。閥芯導(dǎo)向面積大，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、進(jìn)口電動單座籠式調(diào)節(jié)閥結(jié)構(gòu)特征：

●頂式雙導(dǎo)向單座閥，結(jié)構(gòu)緊湊，動作靈敏部件少，易維護(hù)；

●粗壯的閥桿及其一體的閥芯，能承受高負(fù)載而閥芯不至脫落；

●自對中卡入式的閥座易于拆出，而且不需要研磨，就可以達(dá)到嚴(yán)密的關(guān)斷密封。

●閥體按流體力學(xué)原理設(shè)計(jì)成等截面低流阻流道，壓降損失小，容量大，額定流量與系統(tǒng)增大30%。

●閥芯和閥座固定籠設(shè)計(jì)有標(biāo)準(zhǔn)型和嚴(yán)酷工況型（消除氣蝕式，降噪式等），具有更長的使用壽命，更高的抗氣蝕和降噪音性能，只需更換閥座固定籠就可適用于不同工況的需要。

●閥門的關(guān)閉是借助于流體壓力、彈簧反作用力和氣缸推力，具有抵抗非常高的流體壓差的關(guān)斷推力，使閥門關(guān)閉的更加嚴(yán)密。

●雙導(dǎo)向、雙重密封結(jié)構(gòu)，減少了填料外漏的可能。

●該系列調(diào)節(jié)閥可以流開安裝，也可以流關(guān)安裝。

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.
