氣動閥,氣動球閥以壓縮空氣為動力源，接受集散控制系統(tǒng)(DCS)，可編程控制器(PLC)等開關(guān)信號，通過電磁閥可實現(xiàn)對閥門快速位式控制。
氣動閥,氣動球閥采用直通型鑄造閥體，球面經(jīng)特殊工藝加工和硬化處理，使其表面光滑耐磨，具有壽命長、結(jié)構(gòu)緊湊、動作可靠、流通能力大、流阻系數(shù)小、安裝方便及良好的切斷性能等特點。產(chǎn)品廣泛應(yīng)用于造紙、石化、冶金、航天、食品、醫(yī)藥、水處理等行業(yè)，特別適用于高黏度和含有纖維介質(zhì)的工藝控制。
氣動活塞式執(zhí)行機(jī)構(gòu)可分為單作用和雙作用兩種。雙作用使用在失電或失氣時，閥門處于失電或失氣時的位置，以確保繼續(xù)生產(chǎn)。單作用在失電或失氣時，閥門處于原始極限位置(全開或全閉)，以確保生產(chǎn)過程處于**位置。
QJ (D / S) R-type O-intensive small pneumatic valve one kind of cut off the corner of 90 ° rotation of the controlled valve. It consists of pneumatic piston actuator and the composition of O-type ball valve, valve core sphere using cylindrical hole. QJ (D / S) R-type for soft seated ball valve, QJ (D / S) RY-type of seal valve.
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
