为防止水击采用减缓关闭时间，拉长关闭行程和向外泄压等措施。
To protect water hammer, the technologies of enlarging slow-closing time, prolongating closing distance of run and pressure relieving are adopted in this device.
由于阀瓣的关闭行程缩短及弹簧作用可加速关闭效果，减少水锤及水击声。
The disc's shutoff stroke is very short and under the effect of the spring, the valve can close quickly and prevent the big noise from water-hammering.
阀杆开启或关闭行程相对较短，并具有非常可靠的切断动作，使得这种阀门非常适合作为介质的切断或调节及节流使用。
Open or close the valve stem travel relatively short, and very reliable cutting action, making this valve is suitable for medium and cutting off or regulating use.
添加下面两行代码以关闭文档，然后编译并执行程序以生成pdf文档：document . add (chapter1)；document . close ；。
Add following two lines to close the document, then compile and execute the program to generate the PDF document: document.add (chapter1); document.close ;.
当活塞到达进气行程的下止点时，随着空气燃油的混合气进入气缸，进气门关闭。
When the piston reaches the bottom of the intake stroke, the intake valve closes, trapping the air-fuel mixture in the cylinder.
内置的止动装置为动力执行机构提供行程保护，并且作为参考坐标在开启和关闭位置定位阀瓣。
Internal stops provide positive over travel protection for power actuated valves and act as a reference to position the discs in the open and closed positions.
在作功行程，进气门和排气门关闭，火花塞点燃混合气，活塞向下移动。
On the power stroke, the intake valve and exhaust valve close. The spark plug ignites the air-fuel mixture, the piston moves down.
在压缩行程，活塞向上运动，进气门和排气门关闭，活塞压缩混合气。
On the compression stroke, the piston moves up. The intake valve and exhaust valve close. The piston compresses the air-fuel mixture.
进气冲程在活塞位与气缸顶部（进气门开启，排气门关闭）时开始，在活塞到达其行程的底部时结束。
The intake stroke starts with the pistonat the top of the cylinder (intake valve open and exhaust valve closed) and stops with the pistonat the bottom of its travel.
