style="text-indent:25px">減溫減壓閥是減溫減壓裝置中的關(guān)鍵部件，減溫減壓閥的性能直接影響整個減溫減壓裝置的性能?，F(xiàn)役減溫減壓閥基本上是雙座平衡式結(jié)構(gòu)的第三代減溫減壓閥和單座套筒式結(jié)構(gòu)的第四代減溫減壓閥，第三代減溫減壓閥是雙座結(jié)構(gòu)，不易密封，泄漏量大，第三代減溫減壓閥的減溫是在閥瓣上開小孔，減溫水的噴嘴流通面積不變，當(dāng)流量變化較大時，減溫水的霧化效果不能達到使用要求。第四代減溫減壓閥為單座套筒結(jié)構(gòu)，內(nèi)部采用霧化噴嘴，結(jié)構(gòu)復(fù)雜，內(nèi)腔容積較大，并且采用雙球結(jié)構(gòu)。</p><p style="text-indent:25px">減溫減壓裝置是用來做什么的？減壓的。氣動閥門定位器是按力平衡原理設(shè)計工作的，其工作原理是按力平衡原理設(shè)計和工作的。當(dāng)通入波紋管的信號壓力增加時，使杠桿繞支點轉(zhuǎn)動，檔板靠近噴嘴，噴嘴背壓經(jīng)放大器放大后，送入薄膜執(zhí)行機構(gòu)氣室，使閥桿向下移動，并帶動反饋桿（擺桿）繞支點轉(zhuǎn)動，連接在同一軸上的反饋凸輪（偏心凸輪）也跟著作逆時針方向轉(zhuǎn)動，通過滾輪使杠桿繞支點轉(zhuǎn)動，并將反饋彈簧拉伸、彈簧對杠桿的拉力與信號壓力作用在波紋管上的力達到力矩平衡時儀表達到平衡狀態(tài)。減溫減壓裝置裝置在底部的軸裝配空上形狀為雙四方形，這個特點就有利于減溫減壓裝置的轉(zhuǎn)角安裝。</p><div
