This cavitation phenomenon, which cannot be avoided in butterfly valves, is known to be caused by the interference of the flow from the front and rear edges of the valve body, and its reduction can be suppressed by preventing the flow interference. Various types of valves have been proposed in the past, but this study proposes a simple method to suppress cavitation by adding a flexible fiber or flexible sheet fixed behind the valve body.\n　The intensity of cavitation was measured in terms of noise level, and the polyester sheet, which was the most flexible, had the greatest noise suppression effect. In the normal valve without the seat, the noise was reduced by approximately ５dB to 10dB at each valve opening position based on the mid valve opening position, where cavitation is most likely to occur, confirming the suppression effect of the polyester sheet. However, a detailed study will be required in the future to determine the length of sheets and the degree of flexibility required.", "subitem_description_type": "Abstract"}]}, "item_10002_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "大阪産業大学学会"}]}, "item_10002_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN0002870X", "subitem_source_identifier_type": "NCID"}]}, "item_10002_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0287−1394", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "小川, 和彦"}, {"creatorName": "オガワ, カズヒコ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "4332", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "青山, 一樹"}, {"creatorName": "アオヤマ, カズキ", "creatorNameLang": "ja-Kana"}], "nameIdentifiers": [{"nameIdentifier": "4333", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "OGAWA, Kazuhiko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4418", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "AOYAMA, Kazuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4419", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2023-05-12"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "027-038.pdf", "filesize": [{"value": "2.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2100000.0, "url": {"label": "027-038", "url": "https://osu.repo.nii.ac.jp/record/2540/files/027-038.pdf"}, "version_id": "660ba967-8b34-476b-bf88-ee7529f03149"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Cavitation", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Cavitation reductionB", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "utterfly-valve", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Noise", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Pressure loss", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Pipe flow", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "柔軟なファイバーとシートの付加によるバタフライ弁の キャビテーション抑制", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "柔軟なファイバーとシートの付加によるバタフライ弁の キャビテーション抑制"}, {"subitem_title": "Cavitation Reduction of Butterfly Valve by Flexible Fibers and Sheet Materials", "subitem_title_language": "en"}]}, "item_type_id": "10002", "owner": "10", "path": ["12", "16", "555"], "permalink_uri": "https://osu.repo.nii.ac.jp/records/2540", "pubdate": {"attribute_name": "公開日", "attribute_value": "2023-05-12"}, "publish_date": "2023-05-12", "publish_status": "0", "recid": "2540", "relation": {}, "relation_version_is_last": true, "title": ["柔軟なファイバーとシートの付加によるバタフライ弁の キャビテーション抑制"], "weko_shared_id": -1}
