先導(dǎo)式溢流閥，DR20-30/31.5
產(chǎn)品概述
先導(dǎo)式溢流閥DR20-30/31.5是一種高性能液壓控制元件，專為工業(yè)液壓系統(tǒng)設(shè)計(jì)，適用于需要穩(wěn)定壓力控制的場(chǎng)合。該閥采用先導(dǎo)控制結(jié)構(gòu)，通過(guò)主閥和導(dǎo)閥的協(xié)同工作實(shí)現(xiàn)精準(zhǔn)壓力調(diào)節(jié)，確保系統(tǒng)壓力在31.5MPa范圍內(nèi)穩(wěn)定輸出。其通徑為20mm，板式連接設(shè)計(jì)便于安裝，適用于油介質(zhì)環(huán)境，工作溫度范圍為常溫至80℃。產(chǎn)品材質(zhì)選用優(yōu)質(zhì)鑄鐵，密封材料為聚酯，具有耐磨損、壽命長(zhǎng)的特點(diǎn)。138
技術(shù)特點(diǎn)
DR20-30/31.5采用先導(dǎo)式減壓原理，主閥芯與導(dǎo)閥錐閥配合，通過(guò)阻尼孔和彈簧調(diào)節(jié)實(shí)現(xiàn)壓力平衡。當(dāng)系統(tǒng)壓力超過(guò)設(shè)定值時(shí)，導(dǎo)閥開啟，主閥芯在壓差作用下移動(dòng)，實(shí)現(xiàn)溢流功能。該閥具備低噪聲、高響應(yīng)速度的優(yōu)勢(shì)，且內(nèi)流道鑄造工藝優(yōu)化了流通能力，流量可達(dá)600L/min。此外，閥體設(shè)計(jì)支持內(nèi)排或外排控制油路，適配不同液壓回路需求。產(chǎn)品廣泛應(yīng)用于機(jī)床、冶金、礦山等領(lǐng)域，可替代同類進(jìn)口元件。21827
英文介紹（Product Description）
The pilot-operated relief valve DR20-30/31.5 is a precision hydraulic component designed for industrial systems requiring reliable pressure regulation. With a nominal diameter of 20mm and pressure capacity up to 31.5MPa, it ensures stable performance in oil-based hydraulic circuits. The valve features a two-stage design combining a main spool and pilot cone valve, which collaboratively maintain preset pressure levels by adjusting flow through damping orifices and spring mechanisms. Its cast iron body and polyester seals enhance durability under continuous operation.
英文技術(shù)參數(shù)（Technical Features）
The DR20-30/31.5 excels in high-flow applications with a maximum flow rate of 600L/min, while its low-noise design minimizes system vibration. The valve supports both internal and external control oil drainage options, offering flexibility for diverse hydraulic configurations. Its compact plate-mounted structure simplifies integration into existing systems. Ideal for machinery, metallurgy, and mining equipment, this valve delivers performance comparable to international counterparts. The operating temperature range spans from ambient to 80°C, ensuring adaptability in varied environments.31024
應(yīng)用場(chǎng)景
該產(chǎn)品適用于液壓系統(tǒng)中需溢流保護(hù)或壓力穩(wěn)定的環(huán)節(jié)，如注塑機(jī)、壓鑄設(shè)備及工程機(jī)械。其模塊化設(shè)計(jì)便于維護(hù)，且無(wú)需特殊工具即可完成調(diào)試。用戶可根據(jù)實(shí)際需求選擇帶單向閥或不帶單向閥的配置，以滿足不同回路的功能要求。131926
