The friction between ball and seat is tiny when valve is operating

阀开关时，特氟隆球体与阀座之间的磨损极小，于是确保

The seat, disc and pivot pins are combined into one subassembly secured to the inlet side of the body with a locking ring in sizes 3 and smaller.

阀座，阀瓣和枢轴销构成一个分总成，采用尺寸3英寸或更小的锁环固定在阀体进口一侧。

All Trick Flow PowerPort Billet Cylinder Heads for small Ford feature CNC-profiled combustion chambers CNC-ported intake and exhaust runners beryllium copper or ductile iron valve seats and manganese bronze valve guides..

所有的计谋流方坯缸盖PowerPort小福特功能数控异形燃烧室，数控移植进气口和排气选手，铍铜或球墨铸铁阀席位，锰青铜阀门指南。

Lost Motion Minimized- For Type 8510, the taper pin/disc connection and the splined valve shaft with clamped lever and single pivot linkage reduce lost motion between the actuator and valve.

失落的运动最小化，对于类型8510，锥针/盘连接和花键轴与钳制阀杠杆和单支点之间的联系，减少损失的执行器和阀门的议案。

The incinerator was improved as following: 1 improving the differential pressure regulating valve to obtain proper proportion of oil to air;2 machining an oil groove on the copper washer...

为此对焚烧炉进行了改进：①对差压式调节阀进行改造，使油气混合比合适；②在喷油枪前端的铜垫圈上开一个小油槽，增加二次引火源，使火焰根部更加稳定。

Sample matrix are discharged by the pre-column. The mobile phases applied consisted of 0.1% HOAc (pH3.0) acetonitrile-water on extraction column with UV detection at 225nm. Then, coupled-column liquid chromatographic methods for the direct analysis of atrazine and simazine in urine was established. As a result, the system showed good chromatographic property in the on-line analysis of atrazine and simazine in urine.

使用该系统对尿中的莠去净和西玛津残留进行了分离分析，以含有0.1%乙酸的酸性水缓冲液对加标尿液中莠去净类化合物保留在预柱上，干扰分析的大分子被排阻而无保留通过，其它干扰分子保留小而通过，再切换六通阀，以乙腈和0.1%乙酸水溶液进行梯度洗脱，进而在下一级ODS分析柱上进行分离（紫外检测225nm），两种除草剂的分离分析取得了良好的定性定量结果

The method of adjustmeng is:The water from the reflux pipe(2)into the cup(4)should not overflow the edge of the cup(4),but flow out through the overflow pipe.

蒸发锅内水沸腾后，开启进水阀(1)但应注意水源不宜过大过小调节方法一般掌握回水管(2)进入加水杯(4)的水源不从杯口溢出才杯子溢水管流出即可直接调节到蒸馏水从(8)正常流出。

At the end of this paper, we will give seller's optimal buy-price The first chapter of this paper is the traditional auction, including the common values model, private valuable model, and the revenue equivalence theorem.

第四章我们在前面的模型基础上分析投标者的收益和卖者的收益，证明了投标者风险规避程度越高，其阀值会越小，并且指出当一口价满足一定条件时，风险中性的投标者不能从一口价拍卖中获得额外的收益，同时、卖者可以获得不低于普通英式拍卖的收益。

By connecting the pilot valve of stepping electric motor with machinery and hydraulic servomotor device, it can form the stepping microcomputer-based governor for water turbine.

以工业控制级单片机 80C552 为核心，开发出集测频、调速、调功、开停机操作、故障诊断及与上位机通讯等功能于一体的双微机型电气调节器，并与抗油污能力强、定位精度高、漏油量小的步进电机式引导阀及机械液压随动装置相配接，构成了水轮机步进式微机调速器。

Of its light weight, small size, easy to install in the HQ44/45X slightly resistance ball-Like check valve flange between the valve-house by two semi-circular springs and board composition, with the pin fixed to the valve on the valve plate to close the spring deformation, fluid pressure exerted by the spring to open the deformation rapidly, so to protect pipelines from water hammer damage.

其重量轻，体积小，容易安装在法兰之间，阀门内部由两个半圆弹簧和板面组成，用销子固定在阀体上弹簧形变使阀板关闭，流体压力又使其开启弹簧的形变很快，这样能保护管道免受水锤破坏。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
