DBDS30P/31.5直動(dòng)式溢流閥是一種用于液壓系統(tǒng)中的壓力控制元件。它通過(guò)直接作用的方式，將液壓油的壓力與彈簧的彈性力進(jìn)行平衡，從而實(shí)現(xiàn)對(duì)系統(tǒng)壓力的精確控制。

該閥的主要結(jié)構(gòu)包括閥體、閥芯、彈簧和調(diào)節(jié)裝置。閥芯通常采用錐閥結(jié)構(gòu)，這種結(jié)構(gòu)具有良好的密封性能和較高的靈敏度。當(dāng)液壓油的壓力超過(guò)彈簧設(shè)定的壓力值時(shí)，閥芯會(huì)自動(dòng)開啟，使多余的液壓油溢流回油箱，從而保持系統(tǒng)壓力的穩(wěn)定。

DBDS30P/31.5直動(dòng)式溢流閥的額定壓力為31.5MPa，適用于中等壓力范圍的液壓系統(tǒng)。它廣泛應(yīng)用于工程機(jī)械、工業(yè)自動(dòng)化設(shè)備、機(jī)床等領(lǐng)域，能夠有效保護(hù)液壓系統(tǒng)中的其他元件免受過(guò)高壓力的損害。

此外，該閥還具有多種安裝方式，如螺紋連接、板式安裝等，方便用戶根據(jù)實(shí)際需求進(jìn)行選擇。其工作介質(zhì)通常為礦物油或磷酸酯，密封材料多為橡膠，能夠適應(yīng)不同的工作環(huán)境。

The DBDS30P/31.5 direct-acting relief valve is a pressure control element used in hydraulic systems. It operates by directly balancing the hydraulic oil pressure with the spring force to achieve precise control of system pressure.

The main components of this valve include the valve body, valve core, spring, and adjustment mechanism. The valve core typically features a conical structure, which offers excellent sealing performance and high sensitivity. When the hydraulic oil pressure exceeds the preset value of the spring, the valve core automatically opens, allowing excess hydraulic oil to flow back into the tank. This process maintains stable system pressure.

With a rated pressure of 31.5MPa, the DBDS30P/31.5 direct-acting relief valve is suitable for hydraulic systems operating at medium pressure levels. It is widely used in construction machinery, industrial automation equipment, machine tools, and other applications. The valve effectively protects other components in the hydraulic system from damage caused by excessive pressure.

Moreover, this valve offers various installation options, such as threaded connections and plate mounting, providing flexibility for users to choose according to their specific needs. The working medium is usually mineral oil or phosphate ester, and the sealing material is often rubber, enabling the valve to adapt to different working environments.
