多年来,我一直做解放牌载重汽车气路的保养、维修工作。据驾驶员同志反映原括水器开关有时失灵,拆修困难。我根据同志们的意见自制了一种简易括水器开关,近一年来的使用证明,这种结构坚固耐用,好造易修。这种开关比原开关零件少三分之一,压力稳定,不漏气。这种气开关由下座、上体、密封垫、压块和调节开关钮五个零件组成(图1)。压缩空气管接到下座上的两个气道上。当扭动调节开关钮1时,开关钮沿上体2上的螺纹向下移动,开关钮下端压紧压块3和密封垫4,封住气道口,关闭气源。当旋松开关钮时,气流从一个气道顶开密封垫,进入另一个气道,气路接通。
Over the years, I have been doing Jiefang brand truck airway maintenance and repair work. According to the driver comrades reflect the original water closures sometimes malfunction, troubleshooting. According to my comrades, I made a simple water closet switch, the use of the past year proved that this structure is durable, easy to make easy repair. This switch than the original switch parts less than one-third, the pressure is stable, no leakage. This gas switch from the lower seat, the upper body, gaskets, pressure block and adjust the switch button five parts (Figure 1). The compressed air pipe is connected to the two air passages on the lower seat. When the switch knob 1 is twisted, the switch button moves downward along the thread on the upper body 2, the lower end of the switch button pushes the pressure piece 3 and the gasket 4, and seals the airway port and closes the air source. When the knob is loosened, the air flow from one air channel opens the gasket and into the other air channel, the air line is switched on.
