液壓閥
  The hydraulic valve is a pressure oil operations automation components,it is controlled by the pressure of oil,and usually with the use of electromagnetic valve combination,can be used for remote control of hydropower station of oil,gas and water pipeline system off.Commonly used in clamping,control,lubrication oil.
 
  Hydraulic valve is the control component in the hydraulic system,used to control the flow of liquid,pressure and flow,so that the hydraulic actuator(hydraulic cylinder)and its working mechanism for the direction of movement required,velocity(speed)and thrust(torque).
 
  Any of a hydraulic system,no matter how simple,not the lack of hydraulic valve;hydraulic machinery and equipment to the same process,through the different combination and use of hydraulic valve,hydraulic system can be composed of a variety of different circuit structure,the hydraulic valve is the hydraulic technology in most varieties and specifications,the most widely used the most.Active components;a hydraulic system design is reasonable,the reliability of operation and installation and maintenance convenience,the performance and parameters depends largely on the various hydraulic valves the matching is reasonable.
 
  In the hydraulic servo control system,the electro-hydraulic servo valve is the core component of the whole system,the quality of the electro-hydraulic servo valve determines the performance of the system.
 
  Hydraulic valve spool and valve body by the general,control device drives the valve core components:the structure of spool and valve body are varied;the spool valve seat hole or holes(sets),and the main oil external oil pipe outlet(inlet,outlet)and the control port and the oil drain port;hand transfer(dynamic),motor,spring,solenoid,hydraulic pressure,electric hydraulic driving device is operated with the common valve.
 
  液壓閥是一種壓力油操作自動化部件,由油壓控制,通常與電磁閥組合使用,可用于遙控水電站的油氣,水管道系統關閉。常用于夾緊,控制,潤滑油。
 
  液壓閥是液壓系統中的控制部件,用于控制液體,壓力和流量的流動,使液壓致動器(液壓缸)及其工作機構用于所需的運動方向,速度(速度)和推力扭矩)。
 
  任何液壓系統,無論多么簡單,不缺乏液壓閥;液壓機械和設備到同一個過程,通過不同的組合和使用液壓閥,液壓系統可以組成各種不同的回路結構,液壓閥是液壓技術在大多數品種和規格,最廣泛使用的最?;钚越M分;液壓系統設計合理,操作可靠性和安裝維修方便,性能和參數很大程度上取決于各種液壓閥的匹配性是否合理。
 
  在液壓伺服控制系統中,電液伺服閥是整個系統的核心部件,電液伺服閥的質量決定了系統的性能。
 
  液壓閥芯和閥體由一般的,控制裝置驅動閥芯部件:閥芯和閥體的結構不同;滑閥閥座孔或孔(套),主油外油管出口(進,出),控制口和排油口;手動傳動(動態),電機,彈簧,電磁閥,液壓,電動液壓驅動裝置與公共閥一起操作。
