液動刀型閘閥安裝尺寸以及外形圖

液動刀型閘閥產(chǎn)品概述
液動刀型閘閥，又稱刀閘閥或刀型漿閘閥。其應(yīng)用范圍非常廣泛，從礦山、電廠的選煤、排矸、排渣，到城市的污水處理；從水泥、造紙廠的漿液輸送，到食品、衛(wèi)生、醫(yī)藥等專業(yè)管道。超薄設(shè)計的液動刀型閘閥以其體積小、重量輕、阻流小、不積渣，易安裝，易拆卸的優(yōu)點徹底解決了普通閘閥、平板閘閥、球閥、截止閥、調(diào)節(jié)閥、蝶閥等閥門的阻流大，占空間，易積渣，不易安裝和維修等疑難問題。因而大量的通用切斷類閥和調(diào)節(jié)型閥門被刀型閘閥取代。
產(chǎn)品概述
液動刀型閘閥以液壓油為動力完成執(zhí)行動作的一種執(zhí)行器，其操作原理驅(qū)動液壓泵把液壓油通過換向閥壓入液壓缸的上下腔來帶動活塞桿做上下動作，從而帶動閘板的啟閉來達到閥門開關(guān)作用。

液動執(zhí)行器的優(yōu)點
1、輸出推動力要高于氣動執(zhí)行器和電動執(zhí)行器，且液動執(zhí)行器的輸出力矩可以根據(jù)要求進行精確的調(diào)整，并將其通過液壓儀表反應(yīng)出來。
2、傳動更為平穩(wěn)可靠，有緩沖無撞擊現(xiàn)象，適用于對傳動要求較高的工作環(huán)境。
3、調(diào)節(jié)精度高、響應(yīng)速度快，能實現(xiàn)高精確度控制。
4、使用液壓油驅(qū)動，液體本身有不可壓縮的特性，因此液壓執(zhí)行器能輕易獲得較好的抗偏離能力。
5、本身配備有蓄能器，在發(fā)生動力故障時，可以進行一次以上的執(zhí)行操作，減少緊急情況對生產(chǎn)系統(tǒng)造成的破壞和影響，特別適用于長輸送管路自動控制。
6、使用液壓方式驅(qū)動，由于在操作過程中不會出現(xiàn)電動設(shè)備常見的打火現(xiàn)象，因此防爆性能要高于電動執(zhí)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.
