      气动球阀一种转角为90°的旋转类控制阀。四驱小子全集,观潮说课稿,徐子东它由气动活塞式执行机构和O型球阀组成,阀芯采用圆柱形通孔球体。四驱小子全集,观潮说课稿,徐子东QJSR型为软密封球阀、QJSRY型为硬密封球阀。

四驱小子全集

气动阀"气动球阀以压缩空气为动力源,接受集散控制系统(DCS),四驱小子全集,观潮说课稿,徐子东可编程控制器(PLC)等开关信号,通过电磁阀可实现对阀门快速位式控制。

观潮说课稿

气动阀"气动球阀采用直通型铸造阀体,四驱小子全集,观潮说课稿,徐子东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。四驱小子全集,观潮说课稿,徐子东产品广泛应用于造纸、石化、冶金、航天、食品、医药、水处理等行业,特别适用于高黏度和含有纤维介质的工艺控制。

徐子东

气动活塞式执行机构可分为单作用和双作用两种。四驱小子全集,观潮说课稿,徐子东双作用使用在失电或失气时,阀门处于失电或失气时的位置,以确保继续生产。单作用在失电或失气时,阀门处于原始极限位置(全开或全闭),四驱小子全集,观潮说课稿,徐子东以确保生产过程处于安全位置。

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
