In the light of the problems with imported offshore wellhead, such as being bulky and expensive and being inconvenient to mount and maintain, Model HKY65―21 offshore wellhead is developed. This wellhead consists of tubing head assembly, PHK plate gate valve, safety valve, stop valve, clamp, small four-way connection and choke, and it is small-sized, light-weighted, high-strength, corrosion- and abrasion-resistant, reliably sealed and convenient to mount and maintain. Application shows that the wellhead can satisfy the requirements of offshore production with good performance.

3.12.2 采用现场控制第一次合闸后，待起动电流下降，即行断开，看电动机旋转方向是否正确。如果不正确，可更换电动机动力电缆的相序。

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。

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。

As the valve body and valve cover gasket, you can not remove the valve flap or damper circumstances, forced open a gap, into the raw material brought on the list.
