油（气）压开关射嘴——可以通过油缸、气缸控制射嘴的开与关， 可用于任何热塑性胶料的加工，防止溢料、拖丝。特殊地还可用于注塑发泡、硅胶、软胶（tpe、tpu、tpr）等注塑。尤其适合安装在大、中型机器上，可节省大量的胶料。
the switch cylinder for oil (gas) pressure, it can control the opening and closing of the nozzle by gas cylinder and oil cylinder, and can be used in the processing of any thermal plastic sizing material and can prevent overflow and dragline silk. it can also be specially used for the injecting molding for foaming, silicon gel and flexible glue (tpe, tpu and tpr). it is especially suitable for installing on the large and middle-scale machines, and large amount of sizing material can be saved.
本射嘴特点：
the features of this nozzle:
ø 采用机械式锁闭结构,用外力(油压或气动)推动阀芯开启和关闭；ø the mechanical locking structure is used, and the valve core can be opened and closed by pushing with the external force (oil pressure or pneumatic ways)
ø 射嘴的开关状态与熔体压力无关；ø the status of the nozzle is irrelative to the melt pressure;
ø 可承受压力3500 kg/cm2及400°c高温环境；ø it can bear the pressure of 3500 kg/cm2 and the high temperature environment of 400°c;
ø 压力损失小，开关动作快且可靠；ø the pressure loss is less, and the action of the switches is rapid and reliable;
ø 可用于任何胶料(pvc除外)防溢流；ø it can be used for the anti-overflow of any sizing material (excluding pvc);
ø 可外加发热圈，保温效果好；ø the extra heating circle can be added and the thermal preservation effect is very good;
ø 可加装防堵过滤网；ø the anti-blocking filtering mesh can be added;
ø 安装：需加装液压阀或气动阀。installation: the hydraulic valve or pneumatic valve can be added.
