產品描述

減溫減壓裝置系列                                                                                                                        Temperature and pressure reducing device series

DCF固定噴嘴  DCF fixed nozzle

DCF型噴嘴常用于減溫水流量低于DCA型最小可調值(CV值大約低于0.7)的場合。

DCF型噴嘴結構簡單、經濟,當用在噴水流量與蒸汽減溫

調節范圍要求不高(大約5:1)的場合時,可以替代DCA

型彈簧可調霧化噴嘴。

 

The DCF nozzle is often used in the occasion where the

temperature of the cooling water is lower than the minimum

adjustable value of the DCA type (the CV value is less than 0.7).

The DCF nozzle has a simple structure and is economical. When

 it is used in situations where the spray flow rate and steam

temperature adjustment range are not high (about 5: 1), it can

 replace the DCA spring adjustable nozzle.

技術特點:

尺寸 :

DCFP型:- 減溫水連接端:1/2" -  1"(DN15 - DN25)

                - 蒸汽連接端:2" -  6"(DN50 - DN150)

DCFW型:- 減溫水連接端:1/2" -  1"(DN15 - DN25)

                 - 蒸汽連接端:1.1/2" -  4"(DN40 - DN100)

連接方式 :

DCFP & DCFW 型:GB, HG, JB, ANSI, UNI, DIN法蘭(DCFP型也可提供BW對焊式)

混合管道-BW對焊,同管道尺寸

壓力等級 :

減溫水連接端:ANSI 150 - 1500, (PN16-250)

蒸汽連接端:ANSI 150 - 1500, (PN16-250)也可提供更高的壓力等級。

流量 : 可以利用DCF選型手冊所列的Cv值按照通用公式計算。

            水的最大質量流量在任何情況下都不能超過蒸汽流量的25%.

設計型式 : 減溫水入口端與管道垂直(標準):鍛造一體式,由螺紋連接、止退墊片固定的DCF噴嘴。減溫水入口端與管道平行(按需):組焊結構,由鍛件或卷制管焊接構成。

材質 :

        本體:碳鋼或Cr-Mo鋼

        混合管道:同管道材質

 

Technical characteristics:

Size:

DCFP type:-Cooling water connection end: 1/2 "-1" (DN15-DN25)

-Steam connection: 2 "-6" (DN50-DN150)

DCFW type:-Cooling water connection end: 1/2 "-1" (DN15-DN25)

-Steam connection: 1.1 / 2 "-4" (DN40-DN100)

Connection method:

DCFP & DCFW type: GB, HG, JB, ANSI, UNI, DIN flange

(DCFP type can also provide BW butt welding type)

Mixed pipe-BW butt welding, same pipe size

Pressure Level :

Cooling water connection: ANSI 150-1500, (PN16-250)

Steam connection: ANSI 150-1500, (PN16-250)

Higher pressure levels are also available.

Flow: The Cv value listed in the DCF selection manual can be calculated according to the general formula.

The maximum mass flow of water must not exceed 25% of the steam flow under any circumstances.

Design type: The inlet end of the desuperheating water is vertical to the pipe (standard): a forged one-piece DCF nozzle that is fixed by a threaded connection and a backstop gasket.

The inlet end of the desuperheating water is parallel to the pipe (as required): a group welding structure, which is composed of forgings or rolled pipes.

Material:

Body: Carbon steel or Cr-Mo steel

Mixed pipe: same pipe material

該系列減溫器使用DCF固定截面型霧化噴嘴,共有三種型號:

DCFP 型插入式,安裝于法蘭型管座上。

DCFC 型插入式,帶噴水復合腔。

DCFW型對夾式。

 

This series of desuperheaters use DCF fixed section atomizing nozzles,

which are available in three models:

DCFP type plug-in type, mounted on flange type socket.

DCFC plug-in type with water spray compound cavity.

DCFW Wafer type.

 

DCF固定截面型噴嘴

DCF型噴嘴能提供非常精良的霧化度,類似于發動機霧化噴嘴(見圖3)。噴嘴的截面積是固定的,當減溫水流

量變小時,水流速和噴射流也減小。在噴嘴(2)上游裝有一個螺旋裝置(1)(特殊設計的噴嘴孔板),使水呈螺旋霧化狀噴出,能部分補償以上原因引起的霧化性能的降低,以保證某些場合可以接受的系統可調比。

DCF fixed section nozzle

DCF nozzles provide very fine atomization, similar to engine atomization nozzles (see Figure 3). The cross-sectional area of the nozzle is fixed.

When the amount becomes smaller, the water flow velocity and the jet flow also decrease. A spiral device (1) (specially designed nozzle orifice plate) is installed upstream of the nozzle (2), so that the water is sprayed in a spiral atomization manner, which can partially compensate for the decrease in atomization performance caused by the above reasons, in order to ensure some Occasionally acceptable system adjustable ratio.
