查询词典 difficult position

When entering the diaphragm pressure on the top of the control room to the atmosphere or water by the downstream area of low pressure, the role of the bottom plate in the valve and the pressure below the diaphragm on the pressure value is greater than the top, so the main valve disc to the fully open position; when entering the diaphragm pressure above the control room can not water the lower reaches of the atmosphere or area of low pressure, the role of the diaphragm on the top of the pressure value is greater than the pressure below the value, so will the main valve pressure valve set to fully closed position; when the diaphragm pressure above the value of the control room at the entrance of the middle pressure and outlet pressure, the main valve in the regulator valve on the disk, and its regulation depends on the location of the needle-catheter system and adjustable valve guide of the role of joint control.

当阀门进入隔膜上方控制室内的压力水被排到大气或下游低压区时，作用在阀盘底部和隔膜下方的压力值就大于上方的压力值，所以将主阀阀盘推到完全开启的位置；当进入隔膜上方控制室内的压力水不能排到大气或下游低压区时，作用在隔膜上方的压力值就大于下方的压力值，所以就会把主阀阀盘压到完全关闭的位置；当隔膜上方控制室内的压力值处于入口压力与出口压力中间时，主阀阀盘就处于调节状态，其调节位置取决于导管系统中的针阀和可调导阀的联合控制作用。

The working methods and principles of the ditching machine coming from home and abroad are analyzed and compared in this paper. By combining the present planting style of rape in the southern area of our country and the large scale usage of small rotary cultivation machine, the advantages and disadvantages of ditching mode between former and post-position are compared. Finally, the ditching components of disc pattern are designed by adopting the post-position to realize the mechanization of ditching in rape planting.
