壹、概述(shu)Outline
QJ(D/S)V、QJ(D/S)VY型(xing)精(jing)小型氣(qi)動V型(xing)調節球閥由氣(qi)動活(huo)塞式(shi)執行機構和帶(dai)V型切(qie)口的部分(fen)球面(mian)形的整體(ti)式(shi)球閥組成(cheng)。屬(shu)旋(xuan)轉(zhuan)類調節球閥。
氣(qi)動V型(xing)調節球閥以壓(ya)縮(suo)空氣(qi)為動(dong)力源(yuan)。接(jie)受(shou)控制系(xi)統(tong)來(lai)的4—20mA DC(0—10mA DC)訊號,通(tong)過(guo)電氣(qi)轉(zhuan)換(huan)或電—氣(qi)閥門定位(wei)器(qi)將(jiang)電信號(hao)轉(zhuan)化成(cheng)閥門動作(zuo)所(suo)需要(yao)的(de)氣(qi)信號(hao),對(dui)調節球閥進行調節。
氣(qi)動V型(xing)調節球閥,其流道(dao)通暢(chang),流(liu)量(liang)系(xi)數(shu)大(da),可(ke)調範圍(wei)大(da),密(mi)封性(xing)能好(hao)。其帶(dai)V型切(qie)口的閥芯(xin),對(dui)閥座具有良好的剪切(qie)作用,使該產(chan)品(pin)適用於石(shi)油(you)化工、造(zao)紙(zhi)、汙水處理(li)及冶金等行業(ye),對含有纖維(wei)和顆粒(li)的懸濁(zhuo)液(ye)介質(zhi)進行流量(liang)控制,特別適用於制漿(jiang)、造(zao)紙(zhi)生產(chan)過程中的(de)紙漿(jiang)、白(bai)水、黑(hei)液(ye)、白(bai)液等懸浮顆(ke)粒(li)流體(ti)及濃濁(zhuo)狀流體(ti)介(jie)質(zhi)的自(zi)動調節。
氣(qi)動活(huo)塞式(shi)執行結(jie)構可(ke)分(fen)為單(dan)作用和雙(shuang)作(zuo)用兩(liang)種(zhong)。雙(shuang)作(zuo)用使用在失電或失氣(qi)時(shi),閥門處於失電或失氣(qi)時(shi),閥門處於原(yuan)始極(ji)限位(wei)置(zhi)(全(quan)開(kai)或全(quan)閉),以確(que)保(bao)生產(chan)過程處於安(an)全(quan)位(wei)置(zhi)。
QJ (D / S) V, QJ (D / S) VY fine small pneumatic V-type ball valve by the pneumatic piston actuator and with a V-notch portion of the overall spherical shape of ball valve components. Is a rotating type ball valve.
V-ball valve pneumatic compressed air as power source. Accept the control system to the 4-20mA DC (0-10mA DC) signal through the electrical conversion or electric - gas valve positioner to the valve movement into electrical signals needed gas signal, the ball valve to adjust.
Pneumatic V-ball valve, the flow smooth, flow coefficient, adjustable range, good sealing performance. The V-shaped incision with the spool of the valve seat has a good shearing, so that the product is suitable for petrochemical, paper, sewage treatment and metallurgical industries, containing fibers and particles in suspension media flow control , especially for pulp and paper production process of paper pulp, white water, black liquor, white liquor and other suspended particles in the fluid and the fluid medium Nongzhuo like the automatic adjustment.
Pneumatic piston implementation structure can be divided into single and double acting two. Dual role in the loss of power or loss of use of gas when the valve is out of power or loss of gas when the valve is in the original extreme position (open or closed) to ensure that the production process in a secure location.
