在石油、化工、矿山和冶金等行业中,六通换向阀是一种重要的流体换向设备。该阀安装在稀油润滑系统输送润滑油的管道中。通过变换密封组件在阀体中的相对位置,使阀体各通道连通或断开,从而控制流体的换向和启停。 六通换向阀的性能参数 公称通径(mm)50～150 适用温度(℃)室温～80 公称压力(MPa)1.0 适用介质润滑油 连接形式法兰 强度试验压力(MPa)1.5 密封试验压力(MPa)1.1 耐压试验温度(℃)常温 六通换向阀的工作原理和结构特点 六通换向阀主要由阀体、密封组件、凸轮、阀杆、手柄和阀盖等零部件组成(图1)。阀门由手柄驱动,通过手柄带动阀杆与凸轮旋转,凸轮具有定位驱动与锁定密封组件的开启与关闭功能。手柄逆时针旋转,两组密封组件分别在凸轮的作用下关闭下端的两个通道,上端的两个通道分别与管道装置的进口相通。反之,上端的两个通道关闭,下端两个通道与管道装置的进口相通,实现了不停车换向。 1上阀盖 2手柄 3阀杆 4凸轮 5密封组件 6阀盖 7阀体 (1)六通阀的阀体由隔板分成两腔,每腔都有3个通道,中间为进油口,两端为出油口。阀体为碳钢板焊结构,体积小,质量轻,结构紧凑,提高了材料的利用率,缩短了生产周期,降低了成本。密封面堆焊不锈钢,防锈耐腐蚀,密封面经过精加工后抛光研磨,表面粗糙度Ra≤0.8μm。 (2)六通阀有两组密封组件。每组密封组件(图2)由阀瓣、密封圈、调整块、调节螺钉、夹板和螺栓组成。阀瓣为碳钢板焊件,设有加强筋,即增加阀瓣强度又起导向作用,保证每组阀瓣间的同轴度。阀瓣上镶嵌聚氨脂橡胶圈,该材料具有耐油、耐磨损、性能稳定、密封良好和使用寿命长的特点。在凸轮的作用下,密封圈的球面与阀体密封面相接触产生挤压弹性变形,达到密封效果。调整块和调节螺钉在两组密封组件不能同步到位时可起调整作用,确保各通道密封性能同步到位。 1夹板 2螺栓 3调整块 4阀瓣 5密封圈 6调整螺钉 (3)阀杆与阀体隔板和上阀盖间的轴向密封采用O形圈。 (4)阀体隔板及上阀盖轴孔部位镶有铜套,可减小与O形圈间的摩擦力矩,密封组件开启与关闭灵活,操作力矩小。 (5)上阀盖设有指示牌及限位螺钉,阀杆上安装指针,明确指示各通道的接通状况,易于操作。

In the petroleum, chemical, mining and metallurgical industries, the six-way valve is an important fluid for the device. The valve installed in the thin oil lubrication system to carry the lubricating oil pipeline. Seal components by changing the relative position in the body, so that each channel connected or disconnected valve to control flow of the changeover and start and stop. Six-way valve's performance parameters Nominal diameter (mm) 50 ~ 150 For temperature (℃) at room temperature ~ 80 Nominal pressure (MPa) 1.0 For medium oil The form of flange connection Strength test pressure (MPa) 1.5 Sealing test pressure (MPa) 1.1 Pressure test temperature (℃) at room temperature Six-way valve working principle and structure characteristics Mainly by the six-way valve body, sealing components, cam, valve stem, handle and valve cover and other parts form (Figure 1). Valve driven by the handle, the stem and the cam driven by rotating the handle, cam lock sealed with the positioning drive with the opening and closing function of the component. Handle counterclockwise rotation, two components were sealed under the action of the cam shut off the two channels, the top two channels were connected with the import channel devices. Instead, the top two channels close, the bottom two channels connected with the import channel devices to achieve a non-stop reversing. The handle on the valve cover 1 2 3 4 cam stem seal component 5 7 6 valve cover body (1) six-way valve in the body cavity by a partition into two, each chamber has three channels, the middle of the inlet, at both ends to a port. Valve for the carbon steel plate welding structure, small size, light weight, compact structure, improved material utilization, reduced production cycle and reduce costs. Sealing surface is welded steel, rust resistant, sealing surface after polishing and grinding of finished surface roughness Ra ≤ 0.8μm. (2) six-way valve has two sealing components. Each seal components (Figure 2) by the valve flap, seals, adjusting block, adjustable screws, plywood and bolts. Disc for the carbon steel plate weldment, with ribs, which increase the intensity of erection guide disc, each disc to ensure concentricity between. Polyurethane rubber disc inlaid rings, the material has oil resistance, wear resistance, stable performance, good sealing and long service life. The role of the cam, the ring of spherical sealing surface contacts with the body produce extruded elastic deformation, to seal. Adjustment block and adjust the screw in the two sets of sealing components in place when not to adjust the synchronization role in ensuring the sealing performance of synchronous channels in place. A splint adjustment block 2 bolt 3 4 5 seals valve valve adjustment screw 6 (3) stem and the body between the diaphragm and the valve cover with the axial O-ring seal. (4) valve diaphragm and the valve cover inlaid with copper sleeve shaft hole parts, and O-ring can reduce the friction between the torque to open and close the flexible sealing component in the operation of small moment. (5) on the valve cover with signs and limit screws, install the valve stem pointer, clear instructions connected to each channel condition, easy to operate.
