制冷電磁閥，F(xiàn)DF-5

產(chǎn)品概述

FDF-5制冷電磁閥是一款專為制冷系統(tǒng)設(shè)計(jì)的自動(dòng)控制閥門，適用于氟利昂制冷劑（如F12、F22）、空氣、水等介質(zhì)。該產(chǎn)品采用先進(jìn)的電磁控制技術(shù)，可實(shí)現(xiàn)管路的快速通斷，廣泛應(yīng)用于空調(diào)、冷凍設(shè)備等制冷系統(tǒng)中。其結(jié)構(gòu)緊湊、性能穩(wěn)定，能有效滿足制冷系統(tǒng)的自動(dòng)化控制需求。12

產(chǎn)品特點(diǎn)

FDF-5制冷電磁閥具有啟閉迅速、運(yùn)行可靠、使用壽命長(zhǎng)等優(yōu)勢(shì)。產(chǎn)品采用銅管喇叭連接方式（M14×1.5螺紋接口），安裝便捷。電磁閥線圈支持多種電壓規(guī)格（交流24V-380V，直流12V-220V），適應(yīng)不同工作環(huán)境需求。閥體設(shè)計(jì)考慮了介質(zhì)流向要求，建議在閥前安裝過濾器以保持管道清潔，避免堵塞。產(chǎn)品工作溫度范圍為-40℃至+50℃，能夠適應(yīng)大多數(shù)制冷工況。23

工作原理

當(dāng)電磁閥線圈通電時(shí)，產(chǎn)生的磁場(chǎng)吸起鐵芯，先導(dǎo)閥打開，降低活塞上部壓力，利用壓差推動(dòng)活塞上移使管路暢通。斷電時(shí)，鐵芯在自重和彈簧作用下關(guān)閉先導(dǎo)閥，介質(zhì)通過節(jié)流孔進(jìn)入上腔，結(jié)合活塞自重和彈簧壓力使閥口關(guān)閉。這種間接式常閉設(shè)計(jì)確保了閥門動(dòng)作的可靠性和穩(wěn)定性。15

技術(shù)參數(shù)

通徑規(guī)格為φ8mm，工作壓力范圍0.03-1.7MPa。適用于環(huán)境溫度＜50℃、相對(duì)濕度≤85%的工作環(huán)境。產(chǎn)品采用特殊設(shè)計(jì)的活塞結(jié)構(gòu)，確保在各種壓差條件下都能穩(wěn)定工作。電壓適應(yīng)性強(qiáng)，可在額定電壓-10%至+15%范圍內(nèi)正常工作。25

Product Introduction

The FDF-5 Refrigeration Solenoid Valve is an automatic control valve specially designed for refrigeration systems, suitable for refrigerants such as Freon F12/F22, air, water and other media. Utilizing advanced electromagnetic control technology, this product can quickly open/close pipelines, widely used in air conditioning, refrigeration equipment and other cooling systems. Its compact structure and stable performance effectively meet the automation requirements of refrigeration systems. 13

Key Features

The FDF-5 features fast switching, reliable operation and long service life. With trumpet tube connection (M14×1.5 thread) for easy installation. The solenoid coil supports multiple voltage specifications (AC 24V-380V, DC 12V-220V) to adapt to different working environments. The valve body design considers media flow direction requirements, recommending filter installation upstream to maintain pipeline cleanliness. Operating temperature range covers -40℃ to +50℃, suitable for most refrigeration conditions. 29

Working Principle

When energized, the coil generates magnetic field to lift the iron core, opening the pilot valve to reduce upper piston pressure, using pressure difference to push the piston upward for fluid passage. When de-energized, the core closes the pilot valve by gravity and spring force, while medium enters upper chamber through throttle hole to assist valve closing. This indirect-acting normally-closed design ensures reliable operation. 528

Specifications

The nominal diameter is φ8mm with working pressure range 0.03-1.7MPa. Suitable for environments below 50℃ temperature and 85% relative humidity. The specially designed piston structure ensures stable operation under various pressure conditions. Excellent voltage adaptability allows normal operation within -10% to +15% of rated voltage. 215
