BJS减压式比例先导阀
BJS PRESSURE REDUCING PROPORTIONAL PILOT CONTROL VALVE
BJS减压式比例先导阀(简称先导阀)是为引进美国卡特彼勒(Caterpillar)950、966和980轮式装载机的国产化配套元件。该阀具有操作简单、控制灵敏、工作可靠、安装维修方便、实现远距离控制等优点。适用于装载机、推土机等大中型工程机械对液动换向阀进行比例先导控制。
The BJS pressure reducing proportional pilot control valve (pilot valve) is for the introduction of the 950,966and 980 wheel loaders (U.S.Caterpillar) of home-made kit. It is easy to control sensitive,reliable,easy to install maintenance and realize the advantages of remote control.Applicable to large and medium-sized construction machinery such as loaders, bulldozers etc.On the hydraulic valve for the ratio of pilot control.
原理简介 PRINCIPLE INTRODUCTION
该阀操纵结构有两种,BJS1-B3T5S(或BJS1-B3T4S)为两个手柄,位于两侧,每个阀杆单独动作。BJS1-B3T4S有五个控制口,其中K5和K4口联动,利用K5口功能,控制相应的单向元件,如远控补油阀等,即可在三位阀(液动换向阀中)的基础上,十分便利地实现四位浮动使传统的四位阀结构大为简化。
BJS1-B3T4为单手柄,居中放置,可以操作四个阀杆,根据液压系统的要求,每个杆可以单独动作,也可两个同时动作。
专用推土机设置了特殊定位装置,实现浮动位定位。
It has two kinds of control structure,BJS1-B3T5S(or BJS1-B3T4S) with two handle located on both sides.Each individual stem action.The BJS1-B3T5S with five control ports,K4 and K5 which may be coupled,K5 features the used of the mouth, the one-way control components , such as the far-controlled oil fill valve,and so on,can in the three-valve (in the hydraulic valve) on the basis of very convenient to achieve four floating make the traditional four-valve structure greatly simplified.
BJS1-B3T4 with single handle,placed in the middle,can operate in four stem,in accordance with the requirements of the hydraulic system,each bar can be a separate action,but also at the same time the two movements.
It is set up a special positioning device in private bulldozers,positioning the realization of floating bit.
