單向閥,B-25(B)
產(chǎn)品概述
單向閥B-25(B)是一種用于控制流體單向流動(dòng)的液壓元件,適用于工業(yè)液壓系統(tǒng)、機(jī)械設(shè)備及各類流體控制場景。其核心功能是確保流體(如油液)僅沿單一方向通過,反向流動(dòng)時(shí)自動(dòng)封閉,從而有效防止介質(zhì)倒流或系統(tǒng)壓力波動(dòng)。該產(chǎn)品采用高強(qiáng)度彈簧與精密閥芯結(jié)構(gòu),確保在0.2~0.6MPa的開啟壓力范圍內(nèi)穩(wěn)定工作,同時(shí)兼具低壓力損失(≤0.1MPa)和長壽命特性。B-25(B)可適配管式或板式安裝,廣泛用于回油路背壓控制、執(zhí)行機(jī)構(gòu)保壓等場合,提升系統(tǒng)運(yùn)動(dòng)平穩(wěn)性并減少停機(jī)時(shí)的空氣侵入風(fēng)險(xiǎn)。
英文描述:
The B-25(B) check valve is a hydraulic component designed for unidirectional flow control in industrial systems and machinery. It ensures fluid (e.g., oil) passes only in one direction while automatically blocking reverse flow, preventing backflow and pressure fluctuations. Featuring a robust spring mechanism and precision valve core, it operates stably within an opening pressure range of 0.2~0.6MPa with minimal pressure loss (≤0.1MPa). Compatible with threaded or plate-mounted configurations, it is widely applied in return-line backpressure control and actuator pressure maintenance, enhancing system stability and reducing air ingress during shutdowns. 11727
結(jié)構(gòu)與材質(zhì)
B-25(B)采用直通式或直角式設(shè)計(jì),閥體材質(zhì)為優(yōu)質(zhì)鑄鐵或不銹鋼,內(nèi)部密封元件選用耐磨合金或工程塑料,確保在高壓(≤6.3MPa)和常溫至中溫環(huán)境下長期可靠運(yùn)行。其結(jié)構(gòu)緊湊,安裝便捷,閥芯與閥座經(jīng)精密研磨配合,反向密封性優(yōu)異,泄漏量極低。產(chǎn)品適用于水、油類及弱腐蝕性介質(zhì),且維護(hù)簡單,僅需定期清理閥腔雜質(zhì)即可恢復(fù)性能。
英文描述:
The valve features a straight-through or right-angle design, with a body crafted from high-grade cast iron or stainless steel. Sealing components utilize wear-resistant alloys or engineering plastics, ensuring durability under pressures up to 6.3MPa and moderate temperatures. Its compact structure facilitates easy installation, while the precision-matched valve core and seat deliver exceptional sealing with minimal leakage. Suitable for water, oil, and mildly corrosive media, maintenance involves simple periodic cleaning to preserve performance. 71218
應(yīng)用場景
B-25(B)單向閥廣泛應(yīng)用于工程機(jī)械、冶金設(shè)備、注塑機(jī)等液壓系統(tǒng)的回油路中,用于建立背壓以改善執(zhí)行元件運(yùn)動(dòng)的穩(wěn)定性,并防止停機(jī)時(shí)空氣混入油路。其堅(jiān)固設(shè)計(jì)也適用于礦山機(jī)械等高振動(dòng)環(huán)境,同時(shí)可作為小型系統(tǒng)的簡易背壓閥使用。
英文描述:
This valve is commonly deployed in hydraulic systems of construction machinery, metallurgical equipment, and injection molding machines. It stabilizes actuator movement by creating backpressure in return lines and prevents air entrainment during shutdowns. Its rugged construction suits high-vibration environments like mining equipment, while also serving as a compact backpressure solution for small-scale systems. 21922

簡單介紹
B-25(B) 單向閥背壓閥的結(jié)構(gòu)與單向閥相同,只是選用較強(qiáng)的彈簧,使之產(chǎn)生背壓。P1為進(jìn)油口,P2為出油口。下面只列出背壓閥之技術(shù)規(guī)格,其余請按同一流量查閱單向閥

的詳細(xì)介紹
B-25(B) 單向閥
一、用途
背壓閥一般裝于液壓系統(tǒng)的回油路中,形成回油路上一定的背壓力,以增加工作機(jī)構(gòu)運(yùn)動(dòng)的平穩(wěn)性;赜吐飞涎b有背壓閥,在停車時(shí)可防止空氣從回油路侵入,避免重新開車空氣被顯著壓縮面產(chǎn)生運(yùn)動(dòng)不均勻。背壓閥的結(jié)構(gòu)與單向閥相同,只是選用較強(qiáng)的彈簧,使之產(chǎn)生背壓。

壓力閥的使用與維修
1、溢流閥安裝得離油泵越近越好,回油管道越短越好,以便能調(diào)到低壓力,并在卸荷時(shí)亦可得到小卸荷壓力。
2、溢流閥的回油管路的管接頭一定要擰緊,并使油管浸入油液內(nèi),以免把空氣帶入油內(nèi)而引起壓力振擺及泵發(fā)出響聲。
3、壓力閥滑閥上的小孔及閥座上的小孔易堵塞,堵塞時(shí)對溢流閥來說,會引起無限升壓而引起事故,對其他壓力閥則影響正常工作。因此使用油液必須清潔。當(dāng)小孔堵塞時(shí),應(yīng)卸下來清洗,如果油太臟,則應(yīng)換油或?yàn)V油,以便正常工作。
4、對力振擺或噪音可能是錐閥磨損而引起,可以換一個(gè);也可能是油液中混入空氣,則系統(tǒng)中所有油管必須擰緊,回油管必須浸入油液內(nèi)。
