If as a result of body shell keycap stuck with the key causes of the "key card" failure, may be key in the cap and put a gasket between the pads can be used稍硬some plastic (such as floppy disk jacket abandoned) made, its size is equal to or slightly larger than the key body size, and location by the rod through the ammonium can open a free passage under the square hole, in accordance with its set of poles, the plug cap; use this pad chip cap with the key body to prevent stuck, you can repair button; If as a result of spring fatigue, shrapnel resistance causes large card key failure, then the Special button to open the body, a little stretching to restore flexibility to reset the spring; Remove the key precursor to the resumption of shrapnel.

若是由于键帽与键体外壳卡住的原因造成&卡键&故障，则可在键帽与键体之间放一个垫片，该垫片可用稍硬一些的塑料做成，其大小等于或略大于键体尺寸，并且在按杆通过的位置开一个可使铵杆自由通过的方孔，将其套在按杆上后，插上键帽；用此垫片阻止键帽与键体卡住，即可修复故障按键；若是由于弹簧疲劳，弹片阻力变大的原因造成卡键故障，这时可特键体打开，稍微拉伸复位弹簧使其恢复弹性；取下弹片将键体恢复。

The simulation results show that the spring stiffness and initial force have important effect on the poppet valve's opening displacement, the delay-closing time and the closing velocity, and there must be an optimal matching between those two spring factors.

仿真结果表明，在同时保证阀芯有较大的开启度和较短的滞后关闭时间时，弹簧刚度和预紧力因素之间存在着最佳组合：k=10 N/cm，f=15N；同等地改变预紧力比改变弹簧刚度，对阀门的运动影响更大。

In order to optimize the spring of the reciprocating pump valve and establish the best spring factor matching, the unsteady opening-closing process of the poppet valve was simulated. The simulation based on computational fluid dynamics approach, and the dynamic-grid technology and User Defined Function was conducted to depict the law of motion of the poppet valve.

采用RNG k-ε湍流模型、动网格技术以及用户自定义程序，对往复泵泵阀的启闭过程进行了非定常数值仿真，得出了不同弹簧因素下、阀门从开启到关闭的过程中，阀芯的升程随时间的变化规律、阀的迟滞关闭时间以及阀芯落座的瞬时速度。
