德國洛克進(jìn)口電動減壓閥工作穩(wěn)定可靠經(jīng)久耐用

一、進(jìn)口電動減壓閥結(jié)構(gòu)特點和用處：   

本系列減壓閥主要由閥體、閥座、閥瓣等零件組成，采用雙閥座、雙錐體閥瓣的結(jié)構(gòu)。采用壓力平衡式閥瓣，通過閥瓣升降調(diào)節(jié)壓力可配用BC型或其它型直行程電動執(zhí)行器實現(xiàn)遙控和自動控制。   

本系列產(chǎn)品的減壓比用到0.6較為合適。   

本產(chǎn)品主要用于蒸汽管路，調(diào)節(jié)壓力。廣泛應(yīng)用在熱電聯(lián)產(chǎn)、輕紡、印染、石化、制糖等行業(yè)。

This series of pressure reducing valve is mainly composed of valve body, valve seat, valve disc and other parts, and adopts the structure of double valve seat and double cone valve disc. The pressure balanced valve disc is adopted, and the pressure can be adjusted by lifting the valve disc, and the BC type or other types of direct stroke electric actuators can be used to realize remote control and automatic control.

The decompression ratio of this series of products is 0.6.

This product is mainly used for steam pipeline and pressure regulation. Widely used in cogeneration, textile, printing and dyeing, petrochemical, sugar and other industries.

二、進(jìn)口電動減壓閥描述：

德國LOCKE洛克進(jìn)口電動減壓閥由直行程電子式電動執(zhí)行機(jī)構(gòu)和直通單座閥組成。內(nèi)含飼服功能，接受統(tǒng)一的4-20mA或1-5V·DC的標(biāo)準(zhǔn)信號，將電流信號轉(zhuǎn)變成相對應(yīng)的直線位移，自動地控制調(diào)節(jié)閥開度，達(dá)到對管道內(nèi)流體的壓力的連續(xù)調(diào)節(jié)。當(dāng)管道壓力很高，或者要求降壓幅度較大的減壓場合，不可用自力式減壓閥，必須采用電動減壓閥，電動減壓閥進(jìn)口適用于對泄露量要求嚴(yán)格、閥前后壓差低及有一定粘度和含少量纖維介質(zhì)的場合。

The electric pressure reducing valve imported from Locke lock, Germany, is composed of a straight stroke electronic electric actuator and a straight through single seat valve. It contains feeding function, accepts unified standard signal of 4-20mA or 1-5V · DC, transforms current signal into corresponding linear displacement, and automatically controls the opening of regulating valve to achieve continuous regulation of fluid pressure in the pipeline. When the pipeline pressure is very high or the pressure reduction range is required to be large, the self operated pressure reducing valve cannot be used. The electric pressure reducing valve must be used. The inlet of the electric pressure reducing valve is suitable for the field with strict requirements on leakage, low pressure difference between the front and back of the valve, certain viscosity and a small amount of fiber medium.

四、進(jìn)口電動減壓閥工作原理及應(yīng)用：

進(jìn)口減壓閥工作原理是電動調(diào)節(jié)閥在壓力控制領(lǐng)域的典型應(yīng)用。電動減壓閥通過調(diào)節(jié)一次側(cè)流體的動壓頭，達(dá)到控制減壓閥后壓力的目的。本類閥門在管道中一般應(yīng)當(dāng)水平安裝。適用于對泄露量要求嚴(yán)格、閥前后壓差低及有一定粘度和含少量纖維介質(zhì)的場合。

The working principle of imported pressure reducing valve is a typical application of electric control valve in the field of pressure control. The electric pressure reducing valve controls the pressure behind the pressure reducing valve by adjusting the dynamic head of the primary side fluid. This kind of valve should be installed horizontally in the pipeline. It is suitable for occasions with strict requirements on leakage, low pressure difference between front and back of valve, certain viscosity and a small amount of fiber medium.
