Publication number: 20240133474Abstract: The check valve includes: an inlet pipe body part (23) which includes an inflow port (23b); an outlet pipe body part (25) which includes an outflow port (25b); a mobile body (a reciprocative body (2)). Insides of the inlet pipe body part, the outlet pipe body part, and the valve body (12) are communicated to form a curved flow path from the inflow port toward the outflow port. The reciprocative body includes a valve element (6). The seat (23c) is arranged so as to be capable of supporting the valve element and the inflow port and the seat are arranged parallel to each other. An inner wall surface (23y) on an outside-corner side of the flow path in the inlet pipe body part is formed so as to curve toward a side of the outlet pipe body part as a position gets closer from the inflow port to the seat.Type: ApplicationFiled: March 9, 2022Publication date: April 25, 2024Applicant: ISHIZAKI CO., LTD.Inventors: Nobuyuki Ishizaki, Takeshi Ouchi, Eiji Hara

Patent number: 6823290Abstract: A system for inspecting thermal equipment includes a communication line for connecting a facility site and a management center to each other. At the facility site, an operating state information collecting device collects information related to operating states of the thermal equipment. An information processing device fetches the information via the communication line and executes creation of report data for recording related to inspection data of the thermal equipment and delivers the created report data to the facility site. A center-side modem is interposed between the information processing device and the communication line. An output device provided at the facility site outputs a report based on the delivered report data. The report data is stored in a data storage device at each time of creation of the report data. Thus, the system inspecting thermal equipment allows for a reduction in labor.Type: GrantFiled: January 25, 2002Date of Patent: November 23, 2004Assignee: Miura Co., Ltd.Inventors: Tsuneo Sakamoto, Nobuyuki Ishizaki

Patent number: 6638487Abstract: A method for controlling a NOx removal system in which reductant supply is adjusted according to combustion level in a boiler (1) in which the combustion level is controlled in multiple stages. For a decrease of the combustion level, the reductant supply is kept lower than a level corresponding to a changeover-target combustion level for a period of a set time from the changeover of the combustion level. Thus, when the reductant supply is changed over in response to a changeover of combustion level, the reductant can be prevented from flowing outside as it is unreacted.Type: GrantFiled: March 8, 2001Date of Patent: October 28, 2003Assignees: Miura Co., Ltd., Miura Institute of Research and Development Co., Ltd.Inventors: Satoshi Wakasa, Noboru Takubo, Yukihiro Isshiki, Kouichi Masuda, Nobuyuki Ishizaki
