减压

Federal law caps a spiller's liabilities at $75m, puny given the scale of the disaster. BP has already spent $450m on drilling relief wells, preparing the clean-up and giving grants to states; it has promised to pay all "legitimate" damages.

尽管联邦法规定漏油事故责任人的罚款最高不得超过75，000，000美元，但这和此次的漏油惨剧所带来的费用比起来，简直九牛一毛：英国石油公司一方面已为减压井的钻探工作花费了450，000，000美元，一方面还得为清理工作和州政府准备补助金，并且还已承诺会支付一切"合法"的损失。

Rotate the handle to a certain position, so that the distance between the nozzle baffle within the scope of work, pressure reducing valve to enter the work state of the pressure chamber 5 with the nozzle and the decrease of distance between baffle increases, so promoting the spool, Open the intake valve port 9, that is, air flow to exit the same time, through the pore back to the previous chamber 4, with the pressure regulator spring balance.

将手柄旋转到一定位置，使喷嘴挡板的距离在工作范围内，减压阀就进入工作状态中气室5的压力随喷嘴与挡板间距离的减小而增大，于是推动阀芯，打开进气阀口9，即有气流流到出口，同时，经孔道反馈到上气室4，与调压弹簧相平衡。

OBJECTIVE: To observe the clinical results in the anterior stabile operation of spinal fracture using red blood salvage.
