您要查找的是不是：
- Upstream pressure is sensed under the diaphragm. 上游压力在隔膜下被感应到。
- As upstream pressure increases, the diaphragm pushes against the spring. 当上游压力增加，隔膜就像弹簧施加推力。
- This sensitive spring/diaphragm interaction closely tacks and responds to changes in upstream pressure. 这种灵敏的弹簧/隔膜紧密交互作用过程和响应，改变了上游压力。
- Equipped with a pressure sustaining control which prevents the upstream pressure from dropping below a preset minimum. 配置压力平衡控制器，防止上游压力下降到预先设置的最低压力以下。
- Installed in a mainline it prevents upstream pressure from dropping below a preset minimum. 安装在主管线内，防止上游压力降到预置最小压力以下。
- As upstream pressure decreases under the diaphragm, the spring pushes the stem/seat towards the closed position restricting flow through the pilot. 当隔膜下的上游压力降低时，弹簧就将阀杆/阀座反推向关闭位置，限制流体通过引导装置。
- Installed in a mainline it prevents upstream pressure from dropping below a preset minimum. Solenoid override of the sustaining function allows for electrical on-off operation. 安装在主管线内,防止上游压力降到预置最小压力以下。电磁阀的过载平衡功能使其能够进行电气开-关操作。
- In today's global economic recession, Chinese economy faces a difficult environment, there are many small and medium enterprises to an upstream pressure conduction. 在当今全球经济衰退、中国经济面临困难的大环境下，已有众多中小企业的压力传导到上游。
- Installed on a by-pass line, mainline pressure is accurately controlled by relief of excess pressure. Installed in a mainline it prevents upstream pressure from dropping below a preset minimum. 安装一条旁路管线,通过释放过大的压力实现主管线压力的精确控制。安装在主管线内,防止上游压力降到预置最小压力以下。
- The falls upstream are full of salmon. 该瀑布上流有许多大麻哈鱼。
- We paddled (the canoe) slowly upstream. 我们慢慢地划著(独木舟)逆流而上。
- Prevents upstream pressure from dropping below a preset minimum (adjustable) 防止上游压力下降到预先设置的最低压力(可调节)以下
- The beer comes out of the barrel under pressure. 啤酒受到压力从桶中流出。
- Our pressure vessel is licensed product. 我厂生产的压力容器是授权生产产品。
- Loss of pressure had not registered on the dials. 刻度盘未记录压力下降。
- Air pressure forces the water through the pipe. 空气压力使水通过管道。
- What's the atmospheric pressure today? 今天的气压怎么样？
- The water pressure may need adjusting. 水压可能需要调整。
- Pressure is force per unit area. 压力就是电单位面积上的力。
- He drop out because of the pressure. 由于校规很严，所以他退学了。
