電磁溢流閥 ，DBW30B

產(chǎn)品概述

電磁溢流閥DBW30B是一種組合式液壓控制閥，由溢流閥和電磁換向閥集成而成，主要用于液壓系統(tǒng)的壓力控制和安全保護(hù)。該產(chǎn)品采用特殊鋼材與球墨鑄鐵材質(zhì)制造，適用于礦物液壓油或磷酸酯液壓油介質(zhì)，工作溫度范圍為-30℃至+80℃，公稱(chēng)壓力達(dá)31.5MPa。其設(shè)計(jì)融合了先導(dǎo)式溢流閥的穩(wěn)定性和電磁閥的快速響應(yīng)特性，可實(shí)現(xiàn)系統(tǒng)壓力的精確調(diào)節(jié)和多級(jí)控制。15

工作原理

DBW30B電磁溢流閥通過(guò)電磁鐵的通斷電控制閥芯動(dòng)作，當(dāng)電磁鐵通電時(shí)，先導(dǎo)閥芯移動(dòng)使控制油路接通，主閥芯在壓差作用下開(kāi)啟實(shí)現(xiàn)系統(tǒng)卸荷；斷電時(shí)閥芯復(fù)位，系統(tǒng)恢復(fù)預(yù)設(shè)壓力。該閥采用二節(jié)同心式結(jié)構(gòu)，配備阻尼器和錐閥組件，具有壓力調(diào)節(jié)平穩(wěn)、噪音低、啟閉特性?xún)?yōu)良等特點(diǎn)。其獨(dú)特的內(nèi)流道設(shè)計(jì)增強(qiáng)了流通能力，最大流量可達(dá)30L/min，適用于中高壓液壓系統(tǒng)。416

技術(shù)特點(diǎn)

產(chǎn)品具有三大核心優(yōu)勢(shì)：一是采用鑄造內(nèi)流道技術(shù)，流通截面大且壓力損失小；二是電磁鐵與閥體采用優(yōu)化匹配設(shè)計(jì)，動(dòng)作可靠性高且使用壽命長(zhǎng)；三是主閥芯采用V型控制溝槽結(jié)構(gòu)，能實(shí)現(xiàn)流量的漸進(jìn)式調(diào)節(jié)。典型應(yīng)用包括機(jī)床、冶金設(shè)備、工程機(jī)械等需要壓力控制或安全保護(hù)的液壓系統(tǒng)。該型號(hào)提供板式安裝方式，公稱(chēng)通徑為30mm，支持G24或W220等多種電壓規(guī)格的電磁鐵配置。118

產(chǎn)品型號(hào)說(shuō)明

型號(hào)DBW30B采用模塊化命名規(guī)則：其中"DB"代表先導(dǎo)式溢流閥系列，"W"表示帶電磁控制功能，"30"指公稱(chēng)通徑為30mm，"B"為設(shè)計(jì)代號(hào)區(qū)分不同壓力等級(jí)和功能配置。后綴字符如"/3156CG24N9Z5L"依次表示壓力設(shè)定值、控制油配置、電磁鐵電壓等參數(shù)，用戶(hù)可根據(jù)系統(tǒng)需求選擇適配型號(hào)。產(chǎn)品提供多種派生型號(hào)，包括不同壓力級(jí)別（如/100、/315等）和電氣接口（如24V DC或220V AC）。512

Product Overview

The DBW30B solenoid-operated relief valve is a combined hydraulic control valve integrating a relief valve and solenoid directional valve, designed for precise pressure regulation in hydraulic systems. Manufactured with special steel and ductile iron, it operates within -30℃ to +80℃ temperature range and handles mineral-based or phosphate ester hydraulic fluids at nominal pressure up to 31.5MPa. Its compact design ensures reliable pressure adjustment and multi-stage control capabilities.121

Operating Principle

This valve utilizes electromagnetic actuation to switch between pressure holding and system unloading states. When energized, the pilot valve opens to create pressure differential across the main spool, allowing flow bypass; de-energizing restores preset system pressure. The two-stage concentric design incorporates damping orifices and poppet assembly, delivering smooth pressure transition with low noise emission. The optimized internal flow path ensures 30L/min maximum flow capacity for medium-high pressure applications.416

Technical Features

Key advantages include: 1) Cast internal passages minimize pressure drops while maximizing flow efficiency; 2) Custom-matched solenoid ensures high actuation reliability; 3) V-notch spool design enables progressive flow regulation. Typical installations cover machine tools, metallurgical equipment, and construction machinery requiring pressure stabilization or overload protection. The valve features 30mm port size with flange mounting, supporting multiple coil voltage options including 24V DC and 220V AC configurations.125

Model Identification

The DBW30B nomenclature follows modular coding: "DB" denotes pilot-operated relief series, "W" indicates solenoid control feature, "30" specifies 30mm nominal diameter, and "B" designates pressure/function variants. Suffix codes like "/3156CG24N9Z5L" define pressure settings, control oil options, and electrical specifications respectively. Available derivatives cover various pressure ranges (e.g. /100, /315) and electrical interfaces to meet diverse system requirements.1229
