electric
pressure control valve W4F6CP
品牌：德國沃德WODE
一、概述Overview
德國沃德WODE進口W4F6CP電動高壓調節閥又稱抗氣蝕、低噪聲、高壓差調節閥、是德國沃德工程技術人員為滿足50-600MW火力發電機組配套而開發的新型調節閥，該系列產品經過多次的改進，不繼完善，具有新穎性和先進性。
W4F6CP electric pressure control valve, also known as
anti-cavitation and low noise, high-pressure differential regulating valve,
which is the
development of engineering and technical personnel of GER WODE Company To meet the 50-600MW thermal power generating units supporting.The
series has a new and advanced after many improvements and improve.
二、用途Use
安裝在電廠鍋爐高壓差管道上作流量、壓力調節用
Installed in
power plant boiler pipe high-pressure differential for regulating flow
or pressure.
三、結構特征Structure
1、本系列產品采用完合拆裝式結構，操作力距小，閥腔內件（包括閥座、
閥芯、節流組件、密封件等）均可從并閥腔取出，維護保養十分方便，閥體不需從管道上割下，可長期使用。
This series
of products together with complete disassembly structure, operation torque is
small, the valve chamber pieces (including the seat,
Valve, throttle assemblies, seals, etc.) can be removed from the chamber
and the valve, maintenance is very convenient, valve body do not have to be cut
from the pipeline,can be long-term use
2、閥芯為柱塞體平衡式結構，操作力距小，調節靈敏高。
Spool is balanced plunger body
structure, operating torque, the adjustment of high sensitivity.
3、節流組件由多孔板集流式節流環與套筒式節流套組成，且配以均流罩，
因此具有小流量高壓差無氣蝕、大流量、調節性能好，流體排出梳流無噪音的綜合特性，完全滿足了高壓差等苛刻工況的要求，有效地實現了高溫、高壓差流體的流量調節控制，可調性好，調節精度高。
Throttling
component from the porous flow restrictor plate set ring set with integral
throttle sleeve, and
supported by both flow hood, therefore, no pressure differential with low flow cavitation, the flow,
regulated performance, drain fluid flow without noise comb, fully meet the harsh conditions of high pressure and
poor requirements, effective implementation of the high temperature and
pressure differential control of fluid flow control, adjustable, good
regulation and high precision.
4、節流環可在閥門工作行程的55%之內，實現多級減壓節流
Cutting ring can be achieved in
multi-stage vacuum throttle valve work within 55% of stroke.
5、閥芯和閥座密封面堆焊司鈦萊硬質合金，抗沖刷、耐蝕。
Core
and valve seat sealing surface is welded titanium Levin Secretary carbide,
anti-erosion and corrosion resistance.
