That is, it still has contractibility when prop load reaches rated working resistance.卸载阀供支柱卸载回柱用。Unloading valve is used in prop pulling when unloading the prop.（三） 活柱体mobile pillar活柱体是支柱上部承载杆件，它由柱头、弹簧上挂钩、活柱筒等构成。Mobile pillar is the props topping bearing rod, it is made up of column head, the spring hook, mobile column casing and so on.（四） 复位弹簧offsetting spring复位弹簧的作用，是回柱时使活柱体迅速复位，缩短回柱时间。The function of offsetting spring is to offset the mobile column quickly when prop pulling in order to reduce the time of prop pulling.（五） 手把体 handlebar手把体通过连接钢丝和油缸相连接，能绕油缸自由转动，便于操作和搬运，手把体沟槽内装有防尘圈，以防脏物进入油缸。Handlebar is connected to hydro cylinder by the connecting wire, it can do free rotation around hydro cylinder, and it is easy to operate and transport. The handlebar groove is equipped with dust ring in order to prevent dirt from going into hydro cylinder. （六） 活塞 piston 活塞部件由活塞、Y形密封圈、皮碗防挤圈、活塞导向环、O形密封圈（GB1235-76）、活塞防挤圈等组成，它通过O形密封圈（GB1235-76）和活柱体相连接。The piston parts are made up of piston, Y-sealing ring, leather cup extrusion-proof ring, the piston guide ring, O-sealing ring（GB1235-76）, the piston extrusion-proof ring and so on. It is connected to mobile pillar through O-sealing ring. 活塞起活柱导向和油缸密封作用。The piston has the function of mobile pillar guidance and hydro cylinder sealing. （七） 底座体 underseat structure底座体由底座、弹簧挂环、O形密封圈（GB1235-76）、防挤圈等组成，通过连接钢丝和油缸相连接，它是支柱底部密封和承载的零件。The underseat structure is made up of base, spring hook ring, O-sealing ring（GB1235-76）and extrusion-proof ring. It is the part of prop bottom sealing and load-bearing.支柱在使用时将注液枪插入三用阀注液孔中，挂好锁紧套，握紧注液枪手把，高压液体将单向阀打开，高压液体流入支柱下腔，使活柱上升。支柱使金属顶梁紧贴工作面顶板后，松开注液枪手把，这时支柱内腔工作液压为力泵站压力，即支柱达到了额定的初撑力。The prop in use inserts the liquid injection gun into the triple duty valve and then hand up properly the locking sleeve, grip the handlebar of liquid injection gun. The high pressure liquid opens the one-way valve and flow into the prop cavity, and then the mobile pillar goes up. After the prop makes the metal top beam cling to working face top plate, you can loose the liquid injection gun s handlebar, at this time, the prop cavitys working hydraulic pressure becomes pump pressure, that is, the prop reaches the rated setting pressure.随着采煤工作面的推进，工作面顶板作用在支柱上的载荷逐渐增大，当载荷超过支柱额定工作阻力时，高压液体将三用阀中的安全阀打开，液体外溢，支柱下缩。当支柱所受载荷低于额定工作阻力时，在安全阀弹簧的作用下，安全阀关闭，液体停止外溢。上述现象反复出现。因此支柱工作载荷始终保持在额定的工作阻力左右，故称恒阻式支柱。With the push of coal mining working face, the function of its top plate gradually gets bigger on the props load. When the load exceeds the rated working resistance, the high pressure liquid opens the safety valve of the triple duty valve, then the liquid overflows and the prop shrinks. When the prop s load is lower than rated working resistance, the safety valve closes under the effect of safety valve spring, the liquid stop overflowing The above phenomenon appears repeatedly. Therefore, the props working load always keeps around the rated working resistance, it is called constant resistance prop. 工作面回柱时，将卸载手把插入三用阀卸载孔中，转动卸载手把，迫使阀套作轴向移动，从而打开三用阀中的卸载阀，支柱内腔工作液经卸载阀排入老塘，活柱体在自重和复位弹簧作用下回缩，达到 回柱目的。When the working face does the prop pulling, you can insert the unloading handle into the triple duty valves unloading hole, turn around the unloading handle and force valve housing moves in axial direction, therefore open the unloading valve of triple duty valve, the working liquid in the prop cavity is discharged into the old waste through the unloading valve, the mobile pillar retracts under the action of self-weight and spring in order to do the prop pulling. 图三 支柱与注液枪.卸荷手把配合使用The prop coordinates with the liquid injection guns unloading handle 五、支柱的装拆The assembly and disassembly of the prop (一)三用阀的组装 The assembly of triple duty valve 1、组装前的准备：The preparation before assembly(1)合格的三用阀零件,在组装前必须用压力油冲洗干净,任何有毛刺、铁屑或生锈的零件均不得组装；The qualified triple duty valve parts must be rinsed out by pressure oil before assembly.
