Clean and check 1 slowly loosen the gland nut stuffing, packing the release of residual pressure of all components; 2 Remove all old packing, thoroughly clean axle / rod stuffing; 3 Check the shaft / bar have corrosion, dents, scratches or excessive wear; 4 Check whether there are other WATER POWER CONTROL VALVE parts burr, cracks, wear, they will reduce the packing life; 5 Check whether there is too much stuffing the gap, and the shaft / rod eccentric degree; 6 the replacement of defective parts larger; 7 Check the old packing, as BALANCING VALVES the basis of failure analysis to find the reasons for early failure of packing.

缓慢松开填料函的压盖螺母，释放盘根组件内所有的残余压力； 2）移去所有旧的盘根，彻底清洁轴/杆的填料函； 3）检查轴/杆是否有腐蚀、凹痕、划伤或过度磨损； 4）检查其他零件是否有毛刺、裂纹、磨损，它们会减少盘根的寿命； 5）检查填料函是否有过大的间隙，以及轴/杆的偏心程度； 6）更换有较大缺陷的零部件； 7）检查旧盘根，作为失效分析的依据，球阀以找到盘根早期失效的原因。

Moreover, the hot compressive deformation behavior of the RS/PM AZ91 magnesium alloy and AZ91 alloy matrix composite were also investigated, the conclusions are drawn as follows:1. The processing parameters of the atomization-twin rolls quenching technology were optimized as follows: the diameter of the nozzle 1mm, the wheel velocity 25m/s, the pressure of atomization gas 0.3MPa and Ar gas for melt injection 0.1MPa. The RS AZ91 alloy flakes exhibited fine and uniform microstructures. When the flakes were extruded at 673K, extruded velocity of 0.1mm/min and extrusion ratio of 25:1,the magnesium alloy rods with clean surface, uniform dimension and excellent mechanical properties were obtained.2. The RS AZ91 magnesium alloy powders prepared by atomization-twin rolls quenched technology exhibited fine equiaxed grains with the grain size of 1-3μm, the phase constituent included supersaturate solid solution phaseα-Mg and miner fineβ-Mg_(17)Al_(12) phase. The as-extruded materials also exhibited equiaxed grains with the size of 5-7μm and a large number of fineβ-Al_(12)Mg_(17) and fewer AlMg_2Zn phases were detected in the alloy.

Never such lonely, all people all leave me but to go, I do not want with anybody relation, even therefore handset also engine off, but all presses supinely does not live comes from the mind void, thought a sharp sword same thorn I am very painful, one kind comes from soul loneliness.

从来没有这么孤单过，所有的人都离我而去，我不想与任何人联系，甚至因此把手机也停机，可是都压仰不住来自心灵的空虚，想一把利剑一样刺的我生疼，一种来自灵魂的孤单。

The results indicated that during the pressure-keeping stage, the temperature field distributed evenly at the surface and inner part of the billet. In the extrusion process, however, they fluctuated tempestuously which lead to partial overheating on billet surface and result in superficial crack. The flaw analysis and forecast were validated to the experimental result of extruded product.

模拟结果表明，坯料内部和表面的温度场在保压过程中分布均匀，而在挤压过程中则随时间推移而剧烈波动，从而造成坯料表面局部过热，由此导致制件表面龟裂现象的发生。

五谷岂是要辗碎的吗？不是！人并不将它无限期地压了又压，而是叫碾机滚过，碾出谷粒来，并不是为碾碎它。

Dr. Tilson and colleagues developed a screening checklist tool based on the American Academy of Pediatrics and American Diabetes Association guidelines with some modifications. Participating physicians were to screen all children aged 10 to 18 years for elevated BMI. Children with a BMI higher than the 85th percentile were assessed for the risk factors of race/ethnicity, family history of type 2 diabetes, acanthosis nigrans, and hypertension (defined as systolic blood pressure higher than the 90th percentile for age and height).

Tilson医师与同事根据美国小儿医学会与美国糖尿病医学会的治疗指引进行部份修改，研发了一种核对清单；参与的执业医师筛选所有BMI过高的10至18岁儿童，BMI高于前15%的儿童接受筛选种族／信仰、第二型糖尿病家族史、棘状黑色素瘤与高血压（以高于同年龄与身高前10%的收缩压来定义）。

Working Principle Transmitter is composed of sensor and electronic element circuit, pressure of measured medium directly applies on sensor s ceramic diaphragm, force diaphragm to displace tinily in proportion to pressure of medium, under normal working condition, diaphragm displace no more than 0.025mm, electronic circuit detects this displacement, and convert it into standard industrial measuring signal i.e.

工作原理变送器由传感器与电子元件线路组成，被测介质的压力直接作用于传感器的陶瓷膜片上，使膜片产生与介质压力成正比的微小位移，正常工作状态下，膜片最大位移不大于0.025mm，电子线路检测这一位移量后，即把这一位移量转换成对应于这一压力的标准工业测量信号（4~20）mA。超压时膜片直接贴到坚固的陶瓷基体上，由于膜片与基体的间隙只有0.1mm，过载时膜片的最大位移只能是0.1mm，所以从结构上保证了膜片不会产生过大变形。
