Patent number: 11035494Abstract: Provided is a flow rate control apparatus capable of being used continuously when the apparatus is used in equipment that operates continuously, and a flow rate control method for the flow rate control apparatus. A flow rate of a fluid is controlled via any one of control valves disposed in branch passages, respectively. When replacement of the one control valve is determined to be necessary on the basis of a signal outputted from a monitoring portion of the one control valve, the one control valve performing flow rate control is closed, and another control valve disposed in another one of the branch passages, is opened, to perform flow rate control with a flow rate equivalent to that before the replacement. Furthermore, on-off valves disposed at upstream and downstream sides of the closed control valve are closed.Type: GrantFiled: June 21, 2018Date of Patent: June 15, 2021Assignee: FUJIKIN INCORPORATEDInventors: Takashi Funakoshi, Yoshinori Shimomura, Tsuyoshi Tanikawa, Tadayuki Yakushijin

Patent number: 9423037Abstract: A durable diaphragm valve has a single-layer structure consisting of rubber materials. The single-layer structure has a membrane part deforming and moving up and down with opening and closing of a flow channel and a flange part which is provided around said membrane part and sandwiched between a valve body and a bonnet. The flange part has an annular ridge consisting of an upper ridge protruding upward and a lower ridge protruding downward from a position corresponding to said upper ridge. The upper ridge has an inner upper ridge and an outer upper ridge with its protruding height being lower than the inner upper ridge, which are consecutively formed in a staircase pattern.Type: GrantFiled: March 21, 2013Date of Patent: August 23, 2016Assignee: KABUSHIKI KAISHA FUJIKINInventors: Shunji Obara, Yoshinori Shimomura, Masahiko Sogao, Keigo Kobayashi

Publication number: 20150108386Abstract: A diaphragm with excellent durability is provided which can restrain occurrence of a crack resulting from up and down movements of the diaphragm with opening and closing of a flow channel of a diaphragm valve, and a diaphragm valve having this diaphragm. The diaphragm is attached to a diaphragm valve, comprising a membrane part deforming and moving up and down with opening and closing of a flow channel and a flange part which is provided around said membrane part and sandwiched between a valve body and a bonnet, wherein the diaphragm is formed in a curved surface shape where the shape before deformation of the lower surface of said membrane part descends and then ascends from an outer edge part towards a central part.Type: ApplicationFiled: March 21, 2013Publication date: April 23, 2015Inventors: Shunji Obara, Yoshinori Shimomura, Masahiko Sogao, Keigo Kobayashi

Patent number: 5178366Abstract: A fluid flow control valve is provided with a seal comprising a thin metallic film backed by a resiliently deformable body. The seal is mounted on a closure part which may be either the valve stem or the valve seat. The thin film and deformable body are deformed so as to conform to the surface the metallic film seals against as the valve is closed. As the valve is opened, the deformable body returns to its initial state thus returning the thin film to its initial state.Type: GrantFiled: February 7, 1992Date of Patent: January 12, 1993Assignee: Masako KiyoharaInventors: Tetsuya Kojima, Masahiko Nakazawa, Hisayoshi Matsumoto, Yoshinori Shimomura
