詳情介紹:

一、概述Outline

QJ(D/S)RN型精小型氣動螺紋O型切斷球閥是一種轉角為90°的旋轉類控製閥。它由氣動活塞式執行機構和O型球閥組成,閥芯采用圓柱形通孔球體。
該產品以壓縮空氣為動力源,接受集散控製係統(DCS),可編程控製器(PLC)等開關信號,通過電磁閥可實現對閥門快速位式控製。
該產品采用直通型鑄造閥體,球麵經特殊工藝加工和硬化處理,使其表麵光滑耐磨,具有壽命長、結構緊湊、動作可靠、流通能力大、流阻係數小、安裝方便及良好的切斷性能等特點。產品廣泛應用於造紙、石化、冶金、航天、食品、醫藥、水處理等行業,特別適用於高黏度和含有纖維介質的工藝控製。
氣動活塞式執行機構可分為單作用和雙作用兩種。雙作用使用在失電或失氣時,閥門處於失電或失氣時的位置,以確保繼續生產。單作用在失電或失氣時,閥門處於原始極限位置(全開或全閉),以確保生產過程處於安全位置。

QJ (D / S) RN-type O-intensive small pneumatic screw off ball valve angle of 90 ° is a rotary type control valve. It consists of pneumatic piston actuator and the composition of O-type ball valve, valve core sphere using cylindrical hole.
The product is compressed air as power source, accept the distributed control system (DCS), programmable logic controller (PLC) such as switching signals, can be realized through the solenoid valve control valve fast bits.
The product is through casting body, spherical processed by special technology and hardened, making it a smooth surface wear, with a long life, compact structure, reliability, flow capacity, flow resistance coefficient is small, easy to install and good cut-off performance characteristics. Products are widely used in papermaking, petrochemical, metallurgy, aerospace, food, medicine, water treatment and other industries, particularly for high viscosity and contain fiber media process control.
Pneumatic piston actuators 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 position to ensure continued production. Single in the loss 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.
