在液压和气动回路中,经常需要用单向节流阀来调整运动部件的速度,但目前生产的元件大多体积较大安装不便,给设计选用造成困难。为了弥补这方面不足,我院和余姚二轻机械厂协作,研制成功能方便地串接在管道中的VLI型单向节流阀。分A、B两种基型,阀端接口均为细牙标准螺纹。VLI-A型单向节流阀外形小巧,主要用于中低压液压系统。现有8mm、10mm、15mm和18mm四档通径规格。旋转该阀外套壳即可在工作状态方便地调整其流量输出。A型阀能在80kgf/cm~2油压
In hydraulic and pneumatic circuits, one-way throttles are often required to adjust the speed of moving parts, but most of the components currently produced are bulky and inconvenient to install, making it difficult to select designs. In order to make up for this deficiency, our institute and Yuyao No.2 Light Machinery Factory collaborated to develop a VLI one-way throttle valve which can be conveniently connected in series in the pipeline. Sub-A, B two kinds of base type, the valve end interface are fine teeth standard thread. VLI-A one-way throttle small size, mainly used in low pressure hydraulic system. The existing 8mm, 10mm, 15mm and 18mm fourth gear diameter specifications. Turn the valve housing can be easily adjusted in the working state of its flow output. A-type valve can be 80kgf / cm ~ 2 hydraulic pressure
