摘要： PROBLEM TO BE SOLVED: To suppress a vibration caused by inflow of water in a pressurization state from a primary side to a secondary side.
SOLUTION: A negative pressure type pre-action sprinkler includes a water flow detecting device for detecting water supply from the primary side 3 to the secondary side 4 in a case where piping is filled with water on the primary side 3 and the secondary side 4 so as to keep the piping of the secondary side 4 to be in a negative pressure state in a state where the control valve 1 of sprinkler equipment is closed, and then, the control valve 1 is opened by receiving a fire sensing signal from a fire alarm. The control valve 1 is a butterfly valve where a valve body 2 for freely opening/closing a linear flow passage is arranged inside a valve box 5 having the flow passage linearly extending from the primary side 3 to the secondary side 4. Consequently, when pressure water on the primary side flows into the secondary side, water flow in the piping is hardly disturbed, thereby suppressing the vibration to be generated in the piping.

摘要翻译：要解决的问题：抑制从初级侧到次级侧的加压状态的水的流入引起的振动。解决方案：负压型预作用喷洒器包括一个水流检测装置，用于在一次侧3和第二侧上的管道充满水的情况下检测从初级侧3到次级侧4的供水在喷洒装置的控制阀1关闭的状态下使二次侧4的管路保持为负压状态，然后通过接收来自控制阀1的火灾检测信号来打开控制阀1 一个火灾报警器。控制阀1是蝶形阀，其中用于自由打开/关闭线性流动通道的阀体2布置在具有从初级侧3向次级侧4线性延伸的流动通道的阀箱5的内部。因此，当压力一次侧的水流入二次侧，管道内的水流几乎不受干扰，从而抑制管道中产生的振动。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To prevent a packing mounted in a valve box divided part from protruding from a valve box to the outside.SOLUTION: A structure including a locking part (recessed part 13, etc.) having an abutting surface facing an opposite side of the direction of a distal end of a groove at an end of the groove 12 into which a packing is fitted is adopted as a seal structure of a valve box divided part of a butterfly valve V. Accordingly, when the valve box divided part is integrally assembled, an end of the packing is suppressed from protruding from a valve box 1 due to abutting of the packing compressed in a thickness direction and elongating in a longitudinal direction on the abutting surface of the groove.
摘要翻译：要解决的问题：为了防止安装在阀盒分割部分中的包装件从阀箱突出到外部。解决方案：包括具有面向相对侧的抵接表面的锁定部分（凹部13等）的结构作为将蝶形阀V的阀盒分割部分的密封结构作为密封结构，在凹槽12的端部配置有填料的端部的槽的远端的方向被采用。因此，当阀盒分割部为整体组装时，由于与在厚度方向上压缩的包装物抵接而在箱体1的抵接面上沿长度方向伸长，因此能够抑制密封件的端部从阀箱1突出。

摘要： PROBLEM TO BE SOLVED: To provide a heat insulating valve box for high temperature gas preventing a heat insulating material in a roof part from dropping down. SOLUTION: A heat insulating board 15 is mounted in the inner side surface of a ceiling 14 of a valve box cover 3 and supported by covering a lower surface of this board with support members 16a, 16b suspended to the ceiling 14 made of a heat resisting stainless steel plate. In this way, the heat insulating board 15 is prevented from directly touching high temperature gas, a defect of the heat insulating board 15 is prevented, also the heat insulating board 15, even when it is damaged, is prevented from dropping down.
