Reducing gear drives cam rotate to top half-turn and link gear of upper gate move, top disc opens and discharges. Spring device makes disc close and replace with displacement of cam. When cam rotates to bottom half-turn link, gear of sub-layer gate moves, below disc opens and discharges. The disc closes little by little with the displacement of cam. These two actions maintain a closed state of either disc on the pipe. So it can discharges and lock air at the same time.?

减速装置带动凸轮旋转至上半圈时，上层阀门的连杆机构互动，阀板逐渐打开卸灰，随着凸轮的旋转，弹簧机构使阀板逐渐关闭复位；凸轮旋转至下半圈时，下层阀门的连杆机构互动，阀板逐渐打开卸灰，随着凸轮的旋转又使阀板逐渐关闭，这样两个动作使管道上阀板始终有一个是关闭状态，因而，可使卸灰与锁气同时达到目的。

"Kv ·= constant" principle, a sense of freedom laminated springs and valve switching power systems Plug Valves constitute △ P / S =εL S-feeling film work area,ε-spring Hook coefficient, L-valve stroke From this position of valve travel decisions every size of △ P value, if the valve travel position of the Kv and inversely proportional to the G = Kv · a constant value.

"Kv·=常数"原理，自由弹簧和感压膜构成阀门开关动力系统△P/S=εL S—感膜工作面积，ε—弹簧的胡克系数，L—阀行程由此可知阀门的每一个行程位置决定△P值的大小，如果阀行程位的Kv与成反比，则G=Kv·是恒定值。

As solenoid valve the key component in the electronic-control system, the essay focuses on certain solenoid valve construction and characteristics, and set the mathematics model, which used the Simulink to analyze the driving voltage, spring tension and mobile quality, and found that it is complicated on the influence of different factors on solenoid valve, one factor can accelerate the turning off response, but may slower turning on response.

由于电磁阀是电控喷油系统中的关键器件，因此本论文针对某型电磁阀的结构和特点，建立了数学模型。并运用Simulink软件对其进行了仿真研究，分析了驱动电压，回位弹簧预紧力以及运动件质量等对电磁阀响应特性的影响。研究发现影响电磁阀响应特性的因素是十分复杂的，一种因素往往在加速电磁阀关闭响应的同时却会延迟电磁阀开启的响应。

自动膜片弹簧离合器的接合是由不同频率不同脉宽的开关信号驱动电磁阀来实现的，在建立膜片弹簧离合器接合控制模型的基础上，采用预测控制的方法克服了电磁阀开关的滞后。

When the load smaller than the first outlet pressure adjustment valve set pressure, pilot valve Poppet head off an oil chamber, oil chamber 2 is equal to the pressure on the outlet pressure, the main valve of the sliding shaft 2 inside the cavity in the oil a rigid under the action of a small spring at the lowest position, the main valve and the valve slider protruding shoulder posed by all the valve port opens, pressure reducing valve without decompression.

当负载较小，出口压力低于先阀的调定压力时，先导阀的提动头关闭，油腔1、油腔2的压力均等于出口压力，主阀的滑轴在油腔2里面的一根刚性很小的弹簧作用下处于最低位置，主阀滑轴凸肩和阀体所构成的阀口全部打开，减压阀无减压作用。

"Kv ·= constant" principle, a sense of freedom laminated springs and valve switching power systems Plug Valves constitute △ P / S =εL S-feeling film work area,ε-spring Hook coefficient, L-valve stroke From this position of valve travel decisions every size of △ P value, if the valve travel position of the Kv and inversely proportional to the G = Kv · a constant value.

&Kv·=常数&原理，自由弹簧和感压膜构成阀门开关动力系统△P/S=εL S—感膜工作面积，ε—弹簧的胡克系数，L—阀行程由此可知阀门的每一个行程位置决定△P值的大小，如果阀行程位的Kv与成反比，则G=Kv·是恒定值。
