大連式手動調節閥

產品概(gai)述(shu)：

T40H大連式手動調節閥按順(shun)時(shi)針旋(xuan)轉手輪(lun)即可關閉(bi)手動調(diao)節(jie)閥，這時閥(fa)桿帶動(dong)閥(fa)瓣下降，直(zhi)使(shi)兩(liang)錐形密(mi)(mi)封(feng)面接觸達到嚴密(mi)(mi)地將(jiang)管(guan)路(lu)關閉為(wei)止。本企業生產的手動(dong)調(diao)節(jie)閥(fa)適用于(yu)城市集中供熱和(he)區(qu)域供熱的*節(jie)能產品，以調(diao)節(jie)流(liu)量為(wei)主(zhu)。

 產(chan)品特點(dian)：

QSLP智能(neng)型(xing)電(dian)(dian)子式電(dian)(dian)動(dong)(dong)單座調節(jie)閥由PS系(xi)列和3810系(xi)列直行(xing)(xing)程電(dian)(dian)動(dong)(dong)執(zhi)行(xing)(xing)機構(gou)(gou)和低流阻直通單座閥組成(cheng)。（也可配其它品(pin)牌直行(xing)(xing)程執(zhi)行(xing)(xing)機構(gou)(gou)）。電(dian)(dian)動(dong)(dong)執(zhi)行(xing)(xing)機構(gou)(gou)為電(dian)(dian)子式一體(ti)化(hua)結構(gou)(gou)，內有(you)伺(si)服放大器,輸入控制信(xin)號（4-20mADC或1-5VDC）及電(dian)(dian)源即可控制閥門開度,達到對壓力、流量、液位、溫度等(deng)工參數的(de)調節(jie)。電(dian)(dian)動(dong)(dong)單座調節(jie)閥具有(you)動(dong)(dong)作靈敏(min)、連線簡單、流量大、體(ti)積小(xiao)、調節(jie)精度高等(deng)特點。電(dian)(dian)動(dong)(dong)單座調節(jie)閥控制精度和性能(neng)比DKZ型(xing)有(you)明(ming)顯提高。
  產品用途

電動單(dan)(dan)座調節(jie)閥適用(yong)于(yu)對泄露量求嚴格、閥前后壓(ya)差低及(ji)有一(yi)定粘度的場合(he)。電動單(dan)(dan)座調節(jie)閥廣泛應用(yong)于(yu)電力、冶金、化工、石油、環保、輕工、設備等行業。

結構特點(dian)：
   帶現(xian)場電(dian)動手操(cao)功(gong)能，可用(yong)上(shang)升鍵或(huo)下降(jiang)鍵進(jin)行操(cao)作。帶數字顯示窗口，可看到控制(zhi)信號值、反饋(kui)信號值，電(dian)動手操(cao)值。帶斷(duan)控制(zhi)信號故(gu)障判斷(duan)、報(bao)警(jing)及保(bao)護(hu)功(gong)能。即(ji)斷(duan)信號時可使執(zhi)(zhi)行機(ji)構(gou)(gou)或(huo)開；或(huo)關(guan)；或(huo)保(bao)持；或(huo)在0~100%之(zhi)間予置的任意值。帶閥門堵轉故(gu)障判斷(duan)、報(bao)警(jing)及保(bao)護(hu)功(gong)能。在硬件(jian)(jian)上(shang)采用(yong)上(shang)、下限開關(guan)，從(cong)而(er)使執(zhi)(zhi)行器具有(you)雙保(bao)護(hu)功(gong)能。體化結構(gou)(gou)設計(ji)，閥位反饋(kui)組(zu)件(jian)(jian)和伺服(fu)放大器作為兩個獨(du)立部件(jian)(jian)裝(zhuang)入執(zhi)(zhi)行機(ji)構(gou)(gou)內部，直接20mA/4~12mA/12~20mA/0~5V/1~5V/
