Throttle valve the Faxin for needle-shaped cone or belt gaps Cone, the thread for Fagan small teeth, when round-hand, the distance is Faxin mobile, liquid through the area is small, this can cause considerable local resistance, high pressure liquid through the puncture wounds on the consumption of energy and relief.

节流阀的阀芯为针形锥体或带缺口的锥体，阀杆的内螺纹为细牙，当旋转手轮时，阀芯移动的距离不大，液体通过的面积也就很小，此时可以造成很大的局部阻力，高压液体通过小孔时消耗能量而降压。

The impact of the gap between valve neck and valve stem on the temperature of stuffing box were also studied by numerical simulation as well as the thickness of valve neck.

研究结果表明，阀颈长度和阀颈厚度是影响填料函温度的主要因素，阀颈与阀杆之间的间隙尺寸对填料函温度影响很小。

Pilot valves and pilot-type relief valves are the main valves of two parts, pilot valves for cone valve, the flow is a small direct action type relief valves.

先导型溢流阀有先导阀和主阀两部分组成，先导阀为一锥阀，实际上是一个小流量的直动型溢流阀。

Especially for the fluid containing sand, cutting may damage the sealing surface 5, soft sealing gate valve of the operating temperature limits by sealing material Valve When the need for good throttle Cast Gate, Globe, Check Valves control (such as control valves or bypass pipe had a small vent), the stop valve is the most appropriate Ball When the operating temperature between-29oC to 200oC, most manual valve suitable for hydrocarbon and utility systems operations, the use of the ball at 100oC above, applications should be carefully considered when the temperature of the soft sealing material limit should be more than 100oC.

尤其对于含有砂的流体，旋塞阀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当操作温度在-29oC至200oC之间时，大部分手动球阀适应于烃及公用系统的作业中，在100oC以上使用的球阀，应用时要仔细考虑软密封材料的温度限制应该在100oC以上。

However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.

但在大压差工况下，蒸发压力降低，蒸发器负荷需求的液量减少，但实际情况相反，在吸气过热度不变的情况下，由于蒸发压力降低，蒸发器出口压力相应降低，膜片上下的压差变大，使主阀开度增大，供液量增加；但在小压差工况下，蒸发压力上升，蒸发器负荷需求的液量增多，但实际情况是在吸气过热度不变的情况下，由于蒸发压力上升，蒸发器出口压力相应提高，膜片上下的压差变小，使主阀开度减小，供液量减少；在变负荷下亦如此。因此热力膨胀阀在变工况下供液量的调节方面需进一步改进。

Through the valve to reduce the diameter to increase the opening work, the specific ways:① replace a file of small-caliber valve, such as DN32 replaced DN25;② body does not change, the replacement of small diameter spool valve seat Block.

通过把阀的口径减小来增大工作开度，具体办法有：①换一台小一档口径的阀，如DN32换成DN25；②阀体不变更，更换小阀座直径的阀芯阀座。
