摘要： PROBLEM TO BE SOLVED: To perform pressure reduction and flow rate adjustment of high-temperature high-pressure steam by an inexpensive valve.SOLUTION: A porous variable orifice valve V is adopted as a steam pressure reducing valve. The porous variable orifice valve includes a fixed porous disk 2 having a plurality of ports 2a along a channel cross section and a movable orifice disk 3 having a plurality of orifices 3a corresponding to respective ports of the fixed porous disk and attached movably over a position for closing respective ports of the fixed porous disk and a position for opening the ports in a valve box 1. When the movable orifice disk is moved, a correspondence degree of openings between respective ports and their corresponding orifices is changed, a circulation cross section of steam (a) is obtained correspondingly to the correspondence degree and a steam flow rate and a degree of pressure reduction are adjusted. Since the flow rate adjustment and pressure reduction are performed in each individual port and orifice, flow rate adjustment and pressure reducing action are individually performed in the whole circulation cross section of a circulating channel, so that as compared with a case that pressure reducing action is performed only on one position or several positions, noise can be reduced. Since a spread porous variable orifice valve V is used, the price of the valve can be reduced.
摘要翻译：要解决的问题：通过便宜的阀进行高温高压蒸汽的压力降低和流量调节。解决方案：采用多孔可变孔阀V作为蒸汽减压阀。多孔可变孔阀包括固定多孔盘2，其具有沿着通道横截面的多个端口2a和可移动孔板3，活动孔盘3具有对应于固定多孔盘的相应端口的多个孔口3a，并可移动地附接在用于关闭固定多孔盘的各个端口和用于打开阀箱1中的端口的位置。当可移动孔盘移动时，各个端口与其对应的孔口之间的开口的对应程度改变，蒸汽的循环横截面（a）相应于对应度获得，并且调节蒸汽流量和减压度。由于在各个端口和节流孔中进行流量调整和压力降低，所以在循环通道的整个循环截面中分别进行流量调节和减压作用，因此与减压作用相比，仅在一个位置或多个位置执行，可以降低噪声。由于使用散布的多孔可变孔口阀V，所以可以降低阀的价格。

摘要： PROBLEM TO BE SOLVED: To reduce a necessary space for setting a hot blast stove and to efficiently operate a combustion chamber in the hot blast stove.
SOLUTION: There is disclosed the hot blast stove constituted so that combustion gas generated in the combustion chamber 1 is supplied into a heat-storage chamber 2 and a heat-storage material 3 arranged in the heat-storage chamber 2 is allowed to store the heat by the heat-energy which the combustion gas has, and the hot blast is generated by passing the gas into the heat-storage chamber 2 under a state of stopping the supply of the combustion gas, wherein a first hot-blast valve 15 is arranged between one set of combustion chamber 1 and a plurality of heat-storage chambers 2, and the combustion gas can selectively be supplied to the respective heat-storage chamber 2. In such way, even in the case of completing the heat-storage in the heat-storage chamber, the combustion chamber allows the other heat-storage chamber to sore the heat. Therefore, when the heat-storage for one heat-storage chamber 2 is completed, the combustion of gas in the combustion chamber 1 is unnecessary to stop, and the combustion chamber 1 can efficiently be operated. Further, since one set of the combustion chamber 1 is made correspondent to the plurality of heat-storage chambers 2, the space needed to set the hot blast stove 20 is made small.

摘要： PROBLEM TO BE SOLVED: To narrow the gap between a valve element and an inner cylinder for reducing the leakage.
SOLUTION: This butterfly valve includes a valve box 20 consisting of an outer cylinder 21 and an inner cylinder 22, a valve stem 25 inserted in the substantial middle of cylinder-axial direction to be orthogonal to a cylinder axis, and a valve element 24 attached to the valve stem 25. Projections 21a, 21b, 22a and 22b are respectively provided on both cylinder-axial ends of the inner circumference of the outer cylinder 21 and the outer circumference of the inner cylinder 22. With the projections, the inner cylinder 22 is supported by the outer cylinder 21 at the both ends to be like a simple beam, and a heat insulting material is arranged between them. When a high-temperature gas flow flows to a conduit, the inner cylinder 22 is supported at the both ends and thermally expands radially outward around the cylinder-axial middle, and the valve element 24 also expands radially outward. Since the inner cylinder 22 and the valve element 24 are made of the same material and their thermal expansivity around the substantial cylinder-axial middle is generally equal, the gap W between the valve element 24 and the inner circumference of the inner cylinder 22 does not change. Accordingly, since the gap W may be designed to be narrow and the leakage can be reduced, the leakage without fluctuation is quantitatively recognizable.

摘要翻译：要解决的问题：为了减小阀元件和内筒之间的间隙以减少泄漏。
解决方案：该蝶阀包括由外筒21和内筒22组成的阀箱20，插入在与缸轴线正交的缸轴方向的实质中间的阀杆25和阀元件24附接到阀杆25.在外筒21的内圆周的两个气缸轴向端部和内筒22的外周上分别设置有突出部21a，21b，22a和22b。内筒22由两端的外筒21支承成简单的梁，在它们之间配置隔热材料。当高温气体流动到导管时，内筒22被支撑在两端并且围绕圆柱体轴向中间向外径向向外扩张，并且阀元件24也径向向外扩张。由于内筒22和阀元件24由相同的材料制成，并且它们在大致圆筒轴向中间周围的热膨胀通常相等，所以阀元件24与内筒22的内圆周之间的间隙W不更改。因此，由于间隙W可以被设计得窄并且可以减小泄漏，因此无波动的泄漏是可定量识别的。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide a water seal type cutoff valve which can prevent sealing water from flowing out to a duct.
SOLUTION: A water level gauge 7 including a level switch 15 which operates when a water level in a drum 14 is equal to a level (indicated by an alternate long and short dash line in the figure) fixed slightly lower than the position of a supply/discharge port 1b, is connected to a supply/discharge pipe 5 joined to the supply/discharge port 1b at the lowermost portion of a valve seat 1. When canceling cutoff by the fluid, an opening/closing valve 8b of a discharge pipe 5b is opened. After it is realized that the sealing water 3 is completely exhausted from a space between two valve plates 2a of a valve body 2 by the operation of the level switch 15 of the water level gauge 7, an actuation for opening the valve body 2 is performed to open the duct. As a result, the sealing water 3 can be certainly prevented from flowing out to the duct.
