旋塞

Be sure to close test cock before pressurizing valve.

在重新对阀门加压之前，请确认关闭测试旋塞阀。

It has the same movement rotated 90 degrees to mention only difference is that Jacket Ball Valve cock body is a sphere, a circular through-hole or channel through its axis.

它具有相同的旋转90度提动作，不同的是旋塞体是球体，有圆形通孔或通道通过其轴线。

Cock valves and ball valves should be in their unopened positions to prevent from the contamination of sealing surfaces by dust.

闸阀、截止阀、节流阀、调节阀、蝶阀等阀门应处于全闭的位置。旋塞阀、球阀应完全处于全开启位置，以防止灰尘沾染密封面。

We suggest the use of a model DET expansion tank, the Watts Governor 80 ball cock and thermal expansion relief valve, or a 530C calibrated pressure relief valve.

我们建议采用型号DET膨胀罐，美国瓦茨Governor 80球旋塞阀和热膨胀安全阀，或者一个型号530C有刻度压力安全阀。

We suggest the use of a model DET expansion tank, the Watts Governor 80 ball cock with integral thermal expansion relief valve, or a 530C calibrated pressure relief valve.

我们建议采用型号DET膨胀罐，美国瓦茨Governor 80球形旋塞带整体热膨胀安全阀，或一个530C刻度压力安全阀。

Four way ball valve ; four way cock ; sealing performance ; operating torque.

四通球阀；四通旋塞；密封性；操作力矩

Ball and plug is the same type of valve, only its closure is a sphere, the sphere rotates around the body axis to achieve open and close a valve.

球阀和旋塞阀是同属一个类型的阀门，只有它的关闭件是个球体，球体绕阀体中心线作旋转来达到开启、关闭的一种阀门。

Open test cock No.1 and No. 3 admitting line pressure to downstream side of second check valve.

开启测试旋塞1号和3号，是管道压力传到第二止回阀的下游一侧。

Cocks, the top cone FLANGE-CONNECTION LIFTING PLUG VALVE ACC.

旋塞锥体的上部有一止回阀。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
