    摘要： An improved spray nozzle assembly for use in a steam desuperheating device that is adapted to spray cooling water into a flow of superheated steam. The nozzle assembly is of simple construction with relatively few components, and thus requires a minimal amount of maintenance. In addition, the nozzle assembly is specifically configured to, among other things, prevent thermal shock to prescribed internal structural components thereof, to prevent “sticking” of a valve element thereof, and to create a substantially uniformly distributed spray of cooling water for spraying into a flow of superheated steam in order to reduce the temperature of the steam.

    摘要： The present invention inserts and retrieves a desuperheating assembly from within a pressurized steam header through an existing conduit that joins the steam header to the surrounding environment. A gate valve is disposed within the connecting conduit obstructing access to the steam header when closed. The spray nozzle of the desuperheating assembly is attached to a fluid supply pipe and is placed within the conduit on the side of the gate valve that is exposed to the ambient environment. A gas impervious seal is produced between the conduit and the fluid supply pipe so as to isolate the spray nozzle between the gate valve and the gas impervious seal. The gate valve is opened exposing the spray nozzle to the steam header. The supply pipe is advanced past the gas impervious seal, which in turn, drives the spray nozzle into the steam header. Water or steam atomized water can be supplied to the spray nozzle from an external source through the supply pipe that extends from the spray nozzle within the steam header, past the gas impervious seal, to a point external of the vessel. When retrieving the spray nozzle from within the steam header, the supply pipe is retracted past the gas impervious seal within the connecting conduit. As such, the spray nozzle is retracted into the connecting conduit past the gate valve. The gate valve is closed and the spray nozzle is isolated from the steam header. The pressure surrounding the spray nozzle is vented to ambient and the spray nozzle can then be removed without adversely effecting the flow of steam within the steam header. The spray nozzle can then be repaired or replaced and returned into the steam header as described.

    摘要翻译： 本发明通过将蒸汽集管连接到周围环境的现有管道从加压蒸汽集管内插入并取回减温组件。 一个闸阀设置在连接管道中，当关闭时阻碍对蒸汽集管的接近。 减温组件的喷嘴连接到流体供应管并且被放置在暴露于周围环境的闸阀侧面的管道内。 在导管和流体供应管之间产生不透气的密封，以便将喷嘴隔离在闸阀和不透气的密封之间。 打开闸阀将喷嘴暴露在蒸汽集管上。 供应管通过不透气密封件，这又将喷嘴驱动到蒸汽集管中。 水或蒸汽雾化水可以从外部源通过从蒸汽集管内的喷嘴延伸通过不透气密封件的供应管供应到喷嘴，直到容器外部。 当从蒸汽集管内取出喷嘴时，供应管通过连接导管内的气体不可渗透密封件缩回。 因此，喷雾喷嘴通过闸阀缩回到连接导管中。 闸阀关闭，喷嘴与蒸汽集管隔离。 围绕喷嘴的压力被排放到环境中，然后可以移除喷嘴，而不会不利地影响蒸汽集管内的蒸汽流。 然后可以如上所述修理或更换喷嘴并将其返回到蒸汽集管中。

    摘要： The steam throttle valve has a number of water injection ducts distributed around the valve axis within a thin-walled hollow member which extends around the valve axis. A thin-walled water supply duct in a bore in the valve casing cover supplies water to the hollow member. The member is annular and is retained between two assembled parts of the valve, namely the cover and a valve cage. Constructing the ducts in this way obviates thermal stress cracking near them.

    摘要： An attemperator in the form of a steam desuperheater is disclosed herein and comprises a water tube adapted to be connected to a source of water under high pressure and a spray tube communicating with the water tube through a flow-control device for controlling the flow of water from the water tube to the spray tube. The spray tube is adapted to be located in a steam line for injecting cooling water into the steam when its temperature exceeds a predetermined temperature and accordingly is formed with one or more nozzles for injecting a spray of water travelling along an expanding swirling path into the steam, the water being atomized into small droplets which easily evaporate in the steam. Preferably, a plurality of nozzles are provided arranged in rows extending axially of the spray tube and the rows are circumferentially spaced apart. Also, the nozzles preferably communicate with the inside of the spray tube through a series of small ports. A piston movable axially within the spray tube controls the quantity of water discharged into the steam.
