节流

Fluid field analysis of high pressure throttle valve and its structure improvement

图为节流装置的基本结构。节流件的种类繁多，其特点和用途如表。

Throttle valve role is the export of high-pressure liquid coolant condensers to reduce and regulate the flow of relief.

节流阀的用途是对冷凝器输出的高压液态制冷剂进行节流降压和调节流量。

The application and working process of throttle valve in injection mold of unbalanced cavities were introduced,and the key points of designing throttle valve was analysed.

介绍了节流阀在非平衡型腔注射模中的应用及模具工作过程，并分析了节流阀的设计要点。

An adjustable stop is further provided for adjustably limiting the movement of the damper element to establish the second position of the damper.

本发明进一步提供了可调挡块，用于可调地限制该节流元件的运动，以形成节流元件的该第二位置。

As a side note, i recently took a drive to a nearby city, about 500 km away and 4800ft of change in elevation...on the way "up" theres a sudden change in elevation for about 100 km but maybe 3000ft elev....i was in a hurry and i was at full throttle almost for the entire trip, and when i reached that steep incline, the rogue slowed down from 150kmph to 120 kmph, even if i had the pedal to the floor, it wont go faster...only after a 45 minutes period of 120kmph it started gaining speed again but didnt reach the 170kmph as i have seen before...when driving back there was no problem at all, even when i was again at full throttle most of the time...both times i was the only occupant of the vehicle on daytime driving and straightways about 50 km long...

附带注记一下。最近我开车到附近的一个城市，路上大约 500 公里远，在约 100 公里内的爬升 4800ft海拔的突升变化，但也许 3000ft 海拔。。。。我是匆忙以及我是在几乎为在整个的旅途的完整节流，我到达该陡峭的斜坡，rogue 速度开始下降，从 150 kmph 到 120 kmph，即使我将油门脚踏它到底，它并没走得更快。。。持续45 分钟内只保持在 120 kmph 然后它开始再次获得速度，但没有达到 170 的 kmph，正如我之前所曾见。。。驾驶回程时始终没有问题，甚至当我再次在完整的节流大部分时间。。。来回程我是该车辆的唯一乘员，白天驾驶及直线路约 50 公里长。。。

The transmutative time of the throttle slice under the instantaneous wallop is studied with a finite element software. It is drawn that the time for maximum deformation of the throttle slice is just related to its structural parameters and material characteristics, and the time will be reduced with increase in the slice thickness.

通过有限元软件对节流阀片受瞬态冲击的变形时间进行了研究，得出了节流阀片受冲击的最大变形时间只与结构参数和材料特性相关，并随阀片厚度增加而减小的结论。

To obtain frequency is mixed take the intermittent breath with sky adjustable comparing, put forward a kind to be based on gas to accuse reversal valve switch from oscillation loop, accuse throttle of series connection of mouth of forerunner of a powerful person through be being enraged, tone sheds a powerful person to leave successively degree, and control aerates to forerunner mouth time, control gas to charge the reversal time of a powerful person then, produce different frequency and the intermittent breath that take sky comparing.

为获得频率和占空比可调的间歇气流，提出了一种基于气控换向阀切换的自振荡回路，通过在气控阀先导口串联节流阀，调节节流阀开度，而控制向先导口充气时间，进而控制气控阀的换向时间，产生不同频率和占空比的间歇气流。

The adiabatic throttle of retaken natural gas is key technology of the underground gas storage operation.

天然气绝热节流是地下储气库回采的关键技术，可以利用节流冷效应实现回采天然气的脱水、脱油。

Based on the boiler structure and operation data, the simulation results of the software is discussed in detail, and the reason of the heat difference in water wall tubes of the boiler is find out, which is the ruin or wear and tear of inlet throttles.

计算结果表明，原设计的节流圈孔径尺寸分布是合理的，水冷壁管产生热偏差的主要原因是节流圈磨损和损坏造成的。

Especially for the fluid containing sand, cutting may damage the sealing surface 5, soft sealing gate valve of the operating temperature limits by the valve seal material good throttle control when needed (such as control valves or bypass pipe had a small vent), the cut-off valve is the most appropriate valve.

尤其对于含有砂的流体，节流会损坏密封表面 5、软密封闸阀的操作温度受密封材料的限制截止阀当需要好的节流控制（如控制阀的旁通管路或有小的排气孔）时，截止阀是最合适的球阀。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

我们将看到越来越多激进的政府政策，这些政策根据企业的国籍来区分经济活动。

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.

如果能够证明某个一阶谓词系统的独立性，那么就能够保证该系统的建立是精炼的，即没有任何一条公理或推理规则是多余的。
