先導(dǎo)式溢流閥DB10A產(chǎn)品中文介紹
先導(dǎo)式溢流閥DB10A是一種用于液壓系統(tǒng)中的壓力控制閥，主要用于維持系統(tǒng)壓力的穩(wěn)定和安全保護。該產(chǎn)品采用先導(dǎo)控制結(jié)構(gòu)，由主閥和先導(dǎo)閥組成，通過先導(dǎo)閥的精密調(diào)節(jié)實現(xiàn)對主閥的控制，具有響應(yīng)速度快、壓力調(diào)節(jié)范圍廣的特點。DB10A閥芯采用錐閥式設(shè)計，配合阻尼孔結(jié)構(gòu)，能夠在系統(tǒng)壓力超過設(shè)定值時自動開啟，將多余液壓油導(dǎo)回油箱，從而保證系統(tǒng)壓力恒定。其內(nèi)部流道采用優(yōu)化設(shè)計，流通能力強，適用于大流量工況。產(chǎn)品材質(zhì)選用高強度鑄鐵，結(jié)構(gòu)緊湊，安裝方式靈活，可適配不同液壓系統(tǒng)的需求。DB10A適用于工程機械、冶金設(shè)備、鍛壓機床等領(lǐng)域，能夠有效降低系統(tǒng)壓力波動，提升設(shè)備運行穩(wěn)定性。該產(chǎn)品設(shè)計注重耐用性和可靠性，適合在中等溫度范圍內(nèi)長期工作。146
Pilot-operated Relief Valve DB10A Product English Introduction
The pilot-operated relief valve DB10A is a pressure control component designed for hydraulic systems, primarily used to maintain stable system pressure and provide safety protection. It features a two-stage control structure combining a main valve and a pilot valve, where the pilot valve precisely regulates the main valve’s operation for rapid response and wide pressure adjustment range. The DB10A utilizes a poppet-type valve core with damping orifices, which automatically opens to divert excess hydraulic oil back to the tank when system pressure exceeds the preset value, ensuring consistent pressure. Its internally optimized flow channels enhance fluid capacity, making it suitable for high-flow applications. Constructed from high-strength cast iron, the valve offers compact dimensions and flexible installation options to accommodate diverse hydraulic system configurations. Ideal for industrial machinery, metallurgical equipment, and forging presses, the DB10A effectively mitigates pressure fluctuations and improves operational stability. The design prioritizes durability and reliability, supporting long-term performance in moderate temperature environments.146
產(chǎn)品功能與應(yīng)用場景
DB10A先導(dǎo)式溢流閥在液壓系統(tǒng)中承擔(dān)多重功能，包括定壓溢流、穩(wěn)壓、系統(tǒng)卸荷及過載保護。通過遙控口連接外部控制元件，可實現(xiàn)遠程壓力調(diào)節(jié)或多級壓力切換。其典型應(yīng)用包括定量泵系統(tǒng)中的壓力穩(wěn)定控制，以及需要周期性卸荷的液壓回路。產(chǎn)品適應(yīng)礦物基液壓油介質(zhì)，工作溫度范圍覆蓋常規(guī)工業(yè)需求，并可通過外排口或內(nèi)排口設(shè)計適配不同油箱布局。此外，DB10A的低噪聲特性使其適用于對工作環(huán)境噪音敏感的場合。4613
Product Features and Applications
The DB10A pilot-operated relief valve serves multiple roles in hydraulic systems, such as pressure regulation, stabilization, system unloading, and overload protection. Its remote control port allows integration with external components for remote pressure adjustment or multi-stage pressure switching. Typical applications include pressure stabilization in fixed-displacement pump systems and hydraulic circuits requiring periodic unloading. Compatible with mineral-based hydraulic oils, the valve operates effectively within standard industrial temperature ranges and supports both internal and external drain configurations for versatile tank arrangements. The low-noise design makes it suitable for noise-sensitive environments.4613
結(jié)構(gòu)設(shè)計與技術(shù)優(yōu)勢
DB10A采用二節(jié)同心式主閥結(jié)構(gòu)，主閥芯與閥套的配合精度高，減少了泄漏風(fēng)險。先導(dǎo)閥部分通過錐閥與彈簧的協(xié)同作用實現(xiàn)靈敏的壓力反饋，而主閥彈簧僅用于復(fù)位，降低了調(diào)壓機構(gòu)的操作力。噴嘴阻尼設(shè)計可平衡主閥芯兩側(cè)壓差，確保開啟與關(guān)閉的穩(wěn)定性。產(chǎn)品提供內(nèi)供內(nèi)排、外供外排等多種控制油路組合方式，滿足不同系統(tǒng)的控制需求。這種模塊化設(shè)計便于維護，同時提升了閥體的抗污染能力。1621
Structural Design and Technical Advantages
The DB10A employs a two-stage concentric main valve structure with high precision between the spool and sleeve to minimize leakage risks. The pilot valve section utilizes a poppet-and-spring mechanism for sensitive pressure feedback, while the main valve spring solely handles resetting, reducing operational force for pressure adjustment. The nozzle damping design balances pressure differentials on both sides of the main spool, ensuring stable opening and closing. Multiple control oil circuit configurations (e.g., internal supply/internal drain or external supply/external drain) are available to meet diverse system requirements. This modular design facilitates maintenance and enhances contamination resistance.1621
