ROPO自立式壓力調(diào)節(jié)閥無(wú)需外加能源，利用被調(diào)介質(zhì)自身能源為動(dòng)力源，引入執(zhí)行機(jī)構(gòu)控制閥芯位置，改變兩端的壓差和流量，使閥前（或閥后）壓力穩(wěn)定。具有動(dòng)作靈敏，密封性好，壓力設(shè)定點(diǎn)波動(dòng)小等優(yōu)點(diǎn)，廣泛應(yīng)用于氣體、液體及蒸汽介質(zhì)減壓穩(wěn)壓或泄壓穩(wěn)壓的自動(dòng)控制。

詳細(xì)介紹

氣缸式自力減壓閥
    ROPO自立式壓力調(diào)節(jié)閥無(wú)需外加能源，利用被調(diào)介質(zhì)自身能源為動(dòng)力源，引入執(zhí)行機(jī)構(gòu)控制閥芯位置，改變兩端的壓差和流量，使閥前（或閥后）壓力穩(wěn)定。具有動(dòng)作靈敏，密封性好，壓力設(shè)定點(diǎn)波動(dòng)小等優(yōu)點(diǎn)，廣泛應(yīng)用于氣體、液體及蒸汽介質(zhì)減壓穩(wěn)壓或泄壓穩(wěn)壓的自動(dòng)控制。
    ◇無(wú)需外加能源，能在無(wú)電無(wú)氣的場(chǎng)所工作，既方便又節(jié)約了能源。
    ◇壓力分段范圍細(xì)且互相交叉，調(diào)節(jié)精度高。
    ◇壓力設(shè)定值在運(yùn)行期間可連續(xù)設(shè)定。
    ◇對(duì)閥后壓力調(diào)節(jié)，閥前壓力和閥后壓力之比可為10：1-10：8。
    ◇橡膠膜片式檢測(cè)，執(zhí)行機(jī)構(gòu)檢測(cè)精度高、動(dòng)作靈敏。
    ◇采用壓力平衡機(jī)構(gòu)，使調(diào)節(jié)閥反應(yīng)靈敏、控制精確。
    ◇維護(hù)量小，介質(zhì)受控。

ROPO Self-operated regulators are available for temperature, pressure, flow, and differential pressure control. They are suitable for all those applications where deviations of the controlled variable from the adjusted set point are acceptable and the set point remains constant over a long time - often during the entire useful life.
Self-operated regulators are especially suitable for applications that would otherwise require high investment due to the auxiliary energy supply system additionally required by other equipment. Therefore, self-operated regulators are frequently used in the wide-ranging networks of gas, water and heat suppliers.
Since self-operated regulators are very reliable in fulfilling their switching and control functions, even or especially when the energy supply fails, they are ideally suited as safety equipment. Type tested devices designed according to the applicable regulations can be used in many fields of application and, at the same time, they have a good price/performance ratio compared to other solutions.
Constant set point – fixed set point control
Easy to install
Also suitable as safety equipment
