品牌：德國沃德WODE

一、概述Overview

德國沃德WODE進(jìn)口W4F6CP電動(dòng)高壓調(diào)節(jié)閥又稱抗氣蝕、低噪聲、高壓差調(diào)節(jié)閥、是德國沃德工程技術(shù)人員為滿足50-600MW火力發(fā)電機(jī)組配套而開發(fā)的新型調(diào)節(jié)閥，該系列產(chǎn)品經(jīng)過多次的改進(jìn)，不繼完善，具有新穎性和先進(jìn)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(diào)節(jié)用

Installed in power plant boiler pipe high-pressure differential for regulating flow or pressure.

三、結(jié)構(gòu)特征Structure

1、本系列產(chǎn)品采用完合拆裝式結(jié)構(gòu)，操作力距小，閥腔內(nèi)件（包括閥座、

閥芯、節(jié)流組件、密封件等）均可從并閥腔取出，維護(hù)保養(yǎng)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(jié)構(gòu)，操作力距小，調(diào)節(jié)靈敏高。

Spool is balanced plunger body structure, operating torque, the adjustment of high sensitivity.

3、節(jié)流組件由多孔板集流式節(jié)流環(huán)與套筒式節(jié)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(diào)節(jié)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(shí)現(xiàn)了高溫、高壓差流體的流量調(diào)節(jié)控制，可調(diào)性好，調(diào)節(jié)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(jié)流環(huán)可在閥門工作行程的55%之內(nèi)，實(shí)現(xiàn)多級(jí)減壓節(jié)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(zhì)合金，抗沖刷、耐蝕。

Core and valve seat sealing surface is welded titanium Levin Secretary carbide, anti-erosion and corrosion resistance.
