升降貨梯液壓閥的基本結(jié)構(gòu)主要包括閥芯、閥體和驅(qū)動(dòng)閥芯在閥體內(nèi)做相對(duì)運(yùn)動(dòng)的操縱裝置。閥芯的主要形式有滑閥、錐閥和球閥;閥體上除有與閥芯配合的閥體孔或閥座孔外,還有外接油管的進(jìn)、出油口和泄油口;驅(qū)動(dòng)閥芯在閥體內(nèi)做相對(duì)運(yùn)動(dòng)的裝置可以是手調(diào)機(jī)構(gòu),也可以是彈簧或電磁鐵,有些場(chǎng)合還采用液壓力驅(qū)動(dòng)。
The basic construction of the hydraulic valve includes a hydraulic lift spool, and driving the spool valve within the valve body for relative movement manipulation apparatus. The main form has a spool valve, poppet valve and ball; the body in addition to a body orifice or valve seat and valve fitting hole, there are external tubing into and out of the oil port and drain; actuated valves core in the valve body for relative movement means may be a manually adjustable mechanism, may be a spring or a solenoid, some occasions also driven by liquid pressure.

升降貨梯液壓閥是利用閥芯在閥體內(nèi)的相對(duì)運(yùn)動(dòng)來(lái)控制閥口的通斷及開(kāi)口的大小,以實(shí)現(xiàn)壓力、流量和方向控制。液壓閥工作時(shí),所有閥的閥口大小、閥進(jìn)、出油口間的壓差以及通過(guò)閥的流量之間的關(guān)系都符合孔口流量公式(q=KA·Δp m),只是各種閥控制的參數(shù)各不相同而已。
Is the use of hydraulic lifts hydraulic valve spool relative movement in the valve body to control the on-off valve port and the size of the opening, in order to achieve pressure, flow and direction control. When the hydraulic valve job, port size of all valves, the valve inlet and outlet pressure difference between the oil and the flow through the relationship between the valve orifice flow equation are consistent with (q = KA · Δp m), just all kinds of valves parameter controls vary it.
