Product Description> Attemper and Reducer Device

Attemper and reducer device of Third Generation

（I）Structure Features
    The third generation WY series attemper and reducer device is designed by our company on basis of years’ design and manufacture experience and absorption of advanced product structure of foreign countries and after technical optimization.
    It consists of reducer system（attemper & reducer valve and throttle plate etc.）, attemper system（water control valve of high differential pressure and throttle valve etc） and safety protection device（safety valve and check valve）. Its main features are as follows：
1.Adopt attemper and reducer valve to shorten length of the whole device, reduce space occupation and decrease engineering investment.
2.Inside attemper and reducer valve, there is throttle mesh cover set to increase atomization effect of cooling water. It protects valve base and valve body, prolong use life of the valve and at the same decreases noise of the device.
3.Temperature adjustment system adopts water control valve of high differential pressure, which not only reduces leakage inside but also spares recycle water branch of water distribution valve of the device’s traditional system, facilitating overall arrangement of the device.
4.Water control valve of high differential pressure of the same caliper has different value of flow coefficient Cv for selection, which greatly improves adjustment sensitivity and accuracy of temperature adjusting system.
5.Travel executive framework is assembled for attemper and reducer valve and water control valve. It gets rid of traditional lever gemel framework, reduces empty travel of intermediate link and further improves sensitivity and accuracy of adjusting system.
6.Pneumatic membrane executive frame is assembled for attemper and reducer valve and water control valve. It satisfies demands of special customers and has advantage of making full use of resources.

（II）Main Performance Indices
1.Inlet steam pressure P1≤ 5.4MPa,t1≤485℃。
2.Outlet flow Q：
Outlet flow of attemper and reducer device Q's change range is 30%Q～100%Q. It's quite ideal to adjust in this range. If there is special requirements, please negotiate otherwise with technical office of our company.
3.Outlet steam pressure P2：
Adjustment accuracy of outlet steam pressure P2 is not less than 2.5 grade.
4.Temperature of outlet steam is t2：
Adjustment accuracy of outlet steam temperature t2 is not less than 2.5 grade.
5.Noise：
In course of normal running, at 1 meter of lower end of attemper and reducer valve, and also 1 meter away from pipe wall, noise grade is not more than 85 db.

（III）Supply Range
Supply range of attemper and reducer device is within mark, mainly are：
1.Reducer system：attemper and reducer valve, and throttle plate etc；
2.Attemper system：water control valve and throttle valve etc；
3.Safety system：safety valve and check valve etc；　　　　　　　　　　　　　　　　　　　 4.Pipeline sytem：steam pipeline, transition pipe and attemper water pipe etc；
5.Matched fittings：stop valve, double-metal thermometer and take-over, pressure meter and three-way pipe, syphon, adapter, flange, cushion, bolt, nut and gasket etc.
