水液氣電磁閥 ，DF-15

產(chǎn)品概述

DF-15水液氣電磁閥是一款采用先導式膜片結(jié)構(gòu)的通用型電磁閥，適用于水、液體、氣體等多種介質(zhì)的自動化控制。該產(chǎn)品通過電磁力驅(qū)動副閥實現(xiàn)主閥的快速啟閉，具有響應靈敏、密封可靠的特點。閥體采用黃銅或鑄鐵材質(zhì)，內(nèi)部密封件為耐用的橡膠膜片，可適應0.03~0.8MPa的工作壓差范圍，介質(zhì)溫度支持0~75℃。其設計兼顧水平與傾斜安裝（傾斜角≤30°），線圈防護等級滿足常規(guī)工業(yè)環(huán)境需求。

The DF-15 water-liquid-gas solenoid valve is a versatile pilot-operated diaphragm valve designed for automated control of water, liquids, and gases. Its electromagnetic actuation mechanism ensures rapid opening/closing via a secondary pilot valve, offering responsive performance and reliable sealing. The valve body is constructed from brass or cast iron with durable rubber diaphragms, compatible with working pressure differentials of 0.03~0.8MPa and medium temperatures up to 75℃. The design supports both horizontal and inclined installation (≤30° tilt), with coil protection suitable for standard industrial environments.

技術(shù)特點

該電磁閥支持AC/DC多種電壓（如AC220V/380V或DC24V/110V），功耗低（12W-15W），線圈溫升控制在80℃以內(nèi)。其結(jié)構(gòu)采用介質(zhì)流向標識設計，確保安裝方向正確；響應時間短（通徑≤50mm時啟閉≤2秒），適用于需頻繁動作的管路系統(tǒng)。產(chǎn)品對介質(zhì)清潔度要求較低，但建議前置過濾器以延長使用壽命。

Technically, the valve supports multiple AC/DC voltages (e.g., AC220V/380V or DC24V/110V) with low power consumption (12W-15W) and coil temperature rise limited to 80℃. The flow-direction indicator ensures proper installation, while fast response time (≤2 seconds for diameters ≤50mm) suits high-frequency piping systems. Though tolerant to moderate介質(zhì)雜質(zhì), a pre-installed filter is recommended for prolonged service life.

應用場景

DF-15廣泛應用于暖通空調(diào)、水利工程、環(huán)保水處理及工業(yè)流體控制領(lǐng)域，如樓宇供水、太陽能設備管路、油路通斷等場景。其常閉型設計在斷電時自動切斷介質(zhì)，保障系統(tǒng)安全；常開型（可選）則適用于需保持常通狀態(tài)的系統(tǒng)。

The DF-15 is widely used in HVAC, hydraulic engineering, environmental water treatment, and industrial fluid control, such as building water supply, solar equipment pipelines, and oil circuit switching. Its normally closed design automatically cuts off介質(zhì) during power failure for safety, while the optional normally open variant suits continuously open systems.

結(jié)構(gòu)優(yōu)勢

主副閥分體結(jié)構(gòu)降低了啟閉所需壓差，膜片式密封減少磨損；銅閥體耐腐蝕，法蘭或螺紋連接（G1/2"至G2"）適配不同管徑。線圈采用鐵殼防護，允許電源波動±10%，適應不穩(wěn)定電網(wǎng)環(huán)境。

The split main/pilot valve structure reduces required pressure differentials for operation, while the diaphragm seal minimizes wear. Brass construction resists corrosion, and flange/threaded connections (G1/2" to G2") fit diverse pipelines. The iron-cased coil tolerates ±10% voltage fluctuations for unstable grid conditions.
