DISCHARGE VALVEARIELB-3492-HH型號(hào)齊全

值器是一種高精度的減壓閥，主要用于壓力定值。目前有兩種壓力規(guī)格的定值器：其氣源壓力分別為輸出壓力范圍分別為。其輸出壓力波動(dòng)不大于最大輸出壓力的常用于需要供給精確氣源壓力和信號(hào)壓力的場(chǎng)合，如氣動(dòng)實(shí)驗(yàn)設(shè)備、氣動(dòng)自動(dòng)裝置等。定值器由三部分組成是直動(dòng)式減壓閥的主閉部分是恒壓降裝置，相當(dāng)于一定差減壓閥。主要作用是使噴嘴得到穩(wěn)定氣源流量是噴嘴擋板裝置和調(diào)壓部分，起調(diào)壓和壓力放大作用，利用被它放大了的氣壓去控制主閥部分。

定值器處于非工作狀態(tài)時(shí)，由氣源輸入的壓縮空氣經(jīng)過(guò)濾器1過(guò)濾后進(jìn)入A室和正室。主閥芯19在彈簧20和氣源壓力作用下壓在閥座上，使A室與B室斷開(kāi)。進(jìn)入A室的氣流經(jīng)由閥口(又稱為活門)12至F室，再通過(guò)恒節(jié)流孔13降壓后，分別進(jìn)入G室和D室。由于這時(shí)尚未對(duì)膜片8加力，擋板5與噴嘴4之間的間距較大，氣體從噴嘴4流出時(shí)的氣流阻力較小，G室及D室的氣壓較低，膜片3及15保持原始位置。進(jìn)入只室的微量氣體主要經(jīng)B室通過(guò)閥口2從排氣口排出；另有一部分從輸出口排空。此時(shí)輸出口無(wú)氣流輸出，由噴嘴流出而排空微量氣體是維持噴嘴擋板裝置工作所必須的，因其為無(wú)功耗氣量，所以希望其耗量越小越好

導(dǎo)致?lián)醢迮c噴嘴之間的間距加大，室和室的氣壓下降。由于室壓力增高，室壓力下降，膜片15在壓差的作用下向上移動(dòng)，使主閥口減小，輸出壓力下降，直到穩(wěn)定到調(diào)定壓力上。此外，在輸入壓力上升時(shí)，E室壓力和F室瞬時(shí)壓力也上升，膜片3在上下差壓的作用下上移，關(guān)小穩(wěn)壓閥口12。由于節(jié)流作用加強(qiáng)，F(xiàn)室氣壓下降，始終保持節(jié)流孔13的前后壓差恒定，故通過(guò)節(jié)流孔13的氣體流量不變，使噴嘴擋板的靈敏度得到提高。當(dāng)輸入壓力降低時(shí)，B室和H室的壓力瞬時(shí)下降，膜片8連同擋板5由于受力平衡破壞而下移，噴嘴4與擋板5間間距減小，G室和D室壓力上升，膜片3和15下移。膜片15下移使主閥口開(kāi)度加大，使B室及H室氣壓回升，
