截止阀

You must prevent circumfluenting to the boiler if the boiler closes chake valve. Rail pressure valve and buffer pistons in the act of gravity can realize the pressurize immediately to make the steam and condensate water not to circumfluent to the boiler in low pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

If the boiler don't close the check valve, then must prevent back flowing to the boiler, valve clack mould weight and buffering piston can seal under gravity action, they make steam and condensed water can't flow back to the boiler under the low air pressure.

If the boiler check valve hasn't be shut, then must prevent steam and water back to the boiler . With the effect of tgravity, check valve and damper piston can immediately get airproof and the steam and water won't back to the boiler even in an atomosphere of low pressure.

At present, we developed J641-64 pneumatic valve fast, J61Y-P55 170V high-voltage cut-off penalty, DK1-3-type single-and double-pole switch, such as new products.

目前，又开发J641-64气动快关阀、J61Y-P55 170V高压截止罚、DK1-3型单双极开关等新产品。

It is worth to be noted that the needed driving current to the MR valve with both annular and radial damping gaps is less than that to the MR valve with annular damping gaps under the cut-off state of the MR valves, which show that the MR valve with both annular and radial damping gaps consumes less energy.

测试结果显示：（1）在相同的工作条件下，同时具有圆环和圆盘阻尼间隙的磁流变阀产生的压降更明显；（2）处于截止状态时，同时具有圆环和圆盘阻尼间隙的磁流变阀的激励电流明显小于具有圆环阻尼间隙的磁流变阀的激励电流，因此采用同时具有圆环和圆盘阻尼间隙的磁流变阀可以节约能量的消耗。

The flow performance characteristics of two check valves, the holistic opening valve and the cantilever valve, were investigated. The prototype of piezoelectric pump with double series-wound chambers was manufactured in two form valves.

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
