產品描述

旁路閥系列                                                                                                                Bypass valve series

DC3700 旁路減溫減壓閥                                                                                            DC3700 bypass desuperheater

    DC3700系列蒸汽減溫減壓站(PRDS)為汽輪機旁路系統通用和緊湊型的蒸汽減溫減壓方案,包括高壓及低壓旁路。

    鍛造球形閥體及高質量的構造材質,擁有比傳統型更均勻的壁厚,高質量的閥體焊接,P/T疲勞效應小。

    東辰所有減溫減壓站的檢測符合TRD 301規范,并滿足至少2000次冷啟動和10000次熱啟動循環。

    蒸汽減壓主要由兩級實現:第一級,鉆孔套筒閥芯調節流量;第二級設計為固定的調節區域,有雙重作用:一,降低流速及噪音聲壓等級,對第一級產生背壓;二,控制混合腔內的蒸汽速度及分布,優化降溫過程。

    第二級可作為消音器具有吸收聲能的功能,減小第一級產生的噪音。多級籠式消音器的間隙優化到可以將噪音頻率降到1kHz-4kHz,或使用特殊設計的盤片堆棧作為消音器時,可產生更顯著的吸聲性能。

    減溫段直接一體式布置于第二級的下游,由蒸汽混合腔裝配噴嘴或東辰不同的噴水減溫器構成。減溫段的選擇必須按照運行工況、工廠布局和過程控制需求來進行。消音器的設計可使其下游混合腔內的蒸汽產生一定的速度保證減溫效率,下游一體式噴水減溫可以防止由于熱沖擊對閥芯和主閥體的破壞。

應用:

    DC3700系列蒸汽減溫減壓站是蒸汽調節領域最佳的解決方案,它整合了高性能流量控制及高效一體式蒸汽減溫性能。

    DC3740系列最主要的應用場合是汽輪機旁路系統,其應用不受實際的壓力、溫度和流量限制。

    大量的應用經驗鑄就了所采用的閥內件能夠很好的減小磨損,更能夠滿足需要極少維護的連續運行場合。

    東辰的各種減溫噴水結構可以裝配在合適的蒸汽調節場合,為不同的蒸汽流量工況提供足夠的減溫水,且擁有極高的可調比。

    東辰擁有各種不同的降噪音解決方案(包括特殊設計迷宮式盤片堆棧),因此可滿足任何適當的噪音要求。

    對于需要大量減溫水的連續蒸汽降溫場合,可以裝配各種不同的噴水混合腔,且噴水混合腔內置保護襯管防止管路損壞。

    DC3700系列最適合現場不能布置直通管路的場合。

    標準配置的執行機構為電動執行機構或單作用、彈簧復位、氣動薄膜執行機構,可配置氣缸執行機構、定位器和其它用于快速動作或緊急動作的相關附件。

    液動執行機構或電液執行機構也可以按照要求配置。

application:

    The DC3700 Series Steam Desuperheater is the best solution for steam conditioning, combining high performance flow control with efficient integrated steam desuperheating.

    The primary application for the DC3740 series is the turbine bypass system, whose application is not limited by actual pressure, temperature and flow.

    A large number of application experience has resulted in the use of trims that reduce wear and tear, and to meet continuous operation where minimal maintenance is required.

    DOCN's various desuperheating spray structures can be fitted in suitable steam conditioning applications to provide adequate desuperheating water for different steam flow conditions with an extremely high ratio of adjustment.

    DOCN has a variety of noise reduction solutions (including the limiphon labyrinth disc stack) to meet any appropriate noise requirements.

    For continuous steam cooling where a large amount of desuperheating water is required, a variety of different injection composite chambers can be assembled, and a protective lining is built in the injection composite chamber to prevent damage to the pipeline.

    The DOCN series is best suited for applications where straight-through piping cannot be placed on site.

    The standard actuators are electric actuators or single-acting, spring-return, pneumatic diaphragm actuators with configurable cylinder actuators, positioners and other accessories for quick action or emergency action.

    The hydraulic actuator or electro-hydraulic actuator can also be configured as required.

規格

 
 

    The DC3700 Series Steam Desuperheating and Reducing Station (PRDS) is the most versatile and compact steam desuperheating solution for steam turbine bypass systems, including high pressure and low pressure bypass.

    Forged spherical valve body and high-quality construction material, with a more uniform wall thickness than the traditional type, high-quality valve body welding, P / T fatigue effect is small.

    All DOCN desuperheating and decompression stations are tested to TRD 301 and meet at least 2000 cold starts and 10,000 hot start cycles.

    The steam decompression is mainly realized by two stages: the first stage, the drilling sleeve valve core regulates the flow rate; the second stage is designed as a fixed adjustment area, which has a dual function: one, reducing the flow rate and the noise sound pressure level, for the first stage Produce back pressure; Second, control the steam velocity and distribution in the composite cavity to optimize the cooling process.

The second stage can function as a silencer to absorb sound energy, reducing the noise generated by the first stage. The gap of the multi-stage cage muffler is optimized to reduce the noise frequency to 1 kHz to 4 kHz, or to use the Limiphon disc stack as a silencer to produce more pronounced sound absorption.

    The desuperheating section is directly arranged in the downstream of the second stage, and is composed of a steam compound chamber assembly nozzle or a DOCN different water spray desuperheater. The selection of the desuperheating section must be based on operating conditions, plant layout and process control requirements. The silencer is designed to produce a certain speed of steam in the downstream composite cavity to ensure the efficiency of temperature reduction. The downstream integrated water spray can prevent the damage of the valve core and the main valve body due to thermal shock.
