簡單介紹

氣動閥,氣動球閥只需要用氣動執行器帶動閥體作90度的旋轉,就可以實現對介質的流量進行截斷和開通的功能。而且只需要很小的轉動力矩就能關閉嚴密。完全平等的閥體內腔爲介質提供了一個阻力很小、並且直通的流道。


氣動閥,氣動球閥  的詳細介紹
      氣動球閥一種轉角爲90°的旋轉類控制閥。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。QJSR型爲軟密封球閥、QJSRY型爲硬密封球閥。

      氣動閥,氣動球閥以压缩空气为动力源,接受集散控制系统(DCS),可编程控制器(PLC)等开关信号,通过电磁阀可实现对阀门快速位式控制。

      氣動閥,氣動球閥采用直通型铸造阀体,球面经特殊工艺加工和硬化处理,使其表面光滑耐磨,具有寿命长、结构紧凑、动作可靠、流通能力大、流阻系数小、安装方便及良好的切断性能等特点。宅男吧广泛应用于造纸、石化、冶金、航天、食品、医药、水处理等宅男吧,特别适用于高黏度和含有纤维介质的工艺控制。

氣動活塞式執行機構可分爲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,以確保繼續生産。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),以確保生産過程處于安全位置。

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
