液动刀型闸阀安装尺寸以及外形图

液动刀型闸阀产品概述
液动刀型闸阀，又称刀闸阀或刀型浆闸阀。其应用范围非常广泛，从矿山、电厂的选煤、排矸、排渣，到城市的污水处理；从水泥、造纸厂的浆液输送，到食品、卫生、医药等专业管道。超薄设计的液动刀型闸阀以其体积小、重量轻、阻流小、不积渣，易安装，易拆卸的优点彻底解决了普通闸阀、平板闸阀、球阀、截止阀、调节阀、蝶阀等阀门的阻流大，占空间，易积渣，不易安装和维修等疑难问题。因而大量的通用切断类阀和调节型阀门被刀型闸阀取代。
产品概述
液动刀型闸阀以液压油为动力完成执行动作的一种执行器，其操作原理驱动液压泵把液压油通过换向阀压入液压缸的上下腔来带动活塞杆做上下动作，从而带动闸板的启闭来达到阀门开关作用。

液动执行器的优点
1、输出推动力要高于气动执行器和电动执行器，且液动执行器的输出力矩可以根据要求进行精确的调整，并将其通过液压仪表反应出来。
2、传动更为平稳可靠，有缓冲无撞击现象，适用于对传动要求较高的工作环境。
3、调节精度高、响应速度快，能实现高精确度控制。
4、使用液压油驱动，液体本身有不可压缩的特性，因此液压执行器能轻易获得较好的抗偏离能力。
5、本身配备有蓄能器，在发生动力故障时，可以进行一次以上的执行操作，减少紧急情况对生产系统造成的破坏和影响，特别适用于长输送管路自动控制。
6、使用液压方式驱动，由于在操作过程中不会出现电动设备常见的打火现象，因此防爆性能要高于电动执行器。
Knife Gate Valve Product Introduction
Type knife gate valve, also known as the knife gate valve or knife gate valve type pulp. Its application scope is very broad, from coal mines, power plants, slag discharge, discharging the gangue, the city sewage treatment; From the cement slurry transportation, paper mills, to food, health, medicine and other professional pipeline. Ultra-thin design type knife gate valve with its small volume, light weight, small flow resistance, no slag, easy to install, easy to remove completely solve the advantages of the common gate valve, flat gate valve, ball valve, globe valve, regulating valve, butterfly valve, choke valve, occupy a space, easy slag deposition, not easy to install and maintenance problems. So a lot of general cut off valve and external regulation valve replaced by type knife gate valve.
Product Introduction
Hydraulic kinfe gate valve powered by hydraulic oil to complete the action of an actuator, its operating principle of driving hydraulic pump by reversing valve of the hydraulic oil pressure into the hydraulic cylinder on inferior vena to drive the piston rod moves up and down, thereby giving impetus to the opening and closing of the damper to achieve the valve switch.

The advantages of hydraulic actuators
1、Output driver than pneumatic actuators and electric actuators, and hydraulic actuator output torque can be accurately adjusted according to the requirement, and through hydraulic pressure instrument.
2、Transmission is more stable and reliable, with buffer without collision phenomenon, suitable for transmission demanding work environment.
3、Adjustment of high precision, fast response speed, can realize high precision control.
4、Using hydraulic drive, has the property of incompressible fluid itself, so the hydraulic actuator can easily obtain a better ability to resist deviation.
5、Equipped with accumulator itself, in the event of a power failure, can be more than one performs operations, reduce the emergency damage and impact on production system, especially suitable for long transmission pipeline automatic control.
6、Use hydraulic drive, because will not appear in the process of operation of electric equipment of the common phenomenon of flint, therefore explosion-proof performance than the electric actuator.
