WTA填料轉(zhuǎn)換閥門類型11.7

概況

三方change-over-valve安全填料法蘭設(shè)計按照EN 1092 - 1和ASME B 16.5分別;可以提供1.0619碳鋼/ WCB,不銹鋼1.4408 / CF8M、低溫碳鋼1.6220 / LCB LCC和特殊材料。

使用

使用轉(zhuǎn)換閥允許必要的維護工作進行一個安全閥,沒有中斷的操作,只需改變相關(guān)的站在閥,從而保護植物免受過量超壓。

植物是防止過度的過剩壓力切換到相關(guān)的備用安全閥門。完整的排污能力時保持change-over-valve開關(guān)從一側(cè)到另一側(cè)。

當使用change-over-valves串聯(lián),手輪子都是通過鏈輪連接以保證同步操作。

設(shè)計特點

由于極低阻力系數(shù)*流偏轉(zhuǎn)。賬戶的安全閥門可以組合與change-over-valveszui大程度相同的公稱尺寸

控制重量緊湊施工方法

減少部分(例如,當安裝安全閥)可以直接焊接上

WTA® Gland Packing Change-Over Valves Type 11.7 
概況

Three-way change-over-valve with safety gland packing in flange design in accordance with EN 1092-1 and ASME B 16.5 respectively; can be supplied in carbon steel 1.0619 / WCB, stainless steel 1.4408 / CF8M, low temperature carbon steel 1.6220 / LCB / LCC and special materials.

Use

The use of change-over valves allows essential maintenance work to be carried out on a safety valve, without interruption of the plant operation, simply by changing over to the relevant stand by valve, thus protecting the plant against excessiv overpressure.

Plants are protected against undue excess pressure by switching over to the relevant standby safety valves. Full blow off capacity is maintained when the change-over-valve switches over from one side to the other.

When using change-over-valves in tandem, both hand wheels are linked via a chain wheel in order to assure simultaneous operation.

Design features

Extremely low resistance coefficients due to optimal flow deflection. On account of this safety valves can be combined to the greatest extent with change-over-valves of the same nominal size 
Compact weight-saving construction method 
Reducing pieces (e.g. when mounting on safety valves) can be welded on directly
