摘要： In order to reduce a pressure loss in a check valve and simplify a manufacturing process, a check valve (10) configured to be disposed in piping of fluid is provided, which includes a valve housing (31) including a valve element (52) and a valve seat (54) therein, a casing (20) that is configured to place the valve housing therein, in which a casing flow path (60) is provided between the casing and the valve housing to make a flow of the fluid in an axial direction of the valve housing. In the valve housing, a communicating hole (38) and sealing portion (34) are formed. The communicating hole that is formed through the valve housing in a thickness direction thereof introduces the fluid, which flows through between the valve element and the valve seat at the open position of the check valve, into the casing flow path. The sealing portion that is provided on an outer surface of the valve housing upstream of the communicating hole in a flow direction of the fluid in the casing flow path, is configured to come into contact with an inner surface of the casing to seal the casing flow path and position the valve housing in a radial direction perpendicular to the axial direction relative to the casing.

摘要： The present disclosure provides a male coupling member detachably couplable to a female coupling member that includes an outer coupling body having a first end inserted and fitted into the female coupling member, a second end opposite to the first end, and a passage extending from the first end to the second end. The male coupling member further includes an inner coupling body disposed coaxially with the outer coupling body at a position closer to the first end, and a filtration member detachably attached to the inner coupling body. The inner coupling body is attachable to and detachable from the outer coupling body from the first end. The filtration member is held in the passage when the inner coupling body is attached to the outer coupling body. The filtration member is detachable when the inner coupling body is detached from the outer coupling body.

摘要： A check valve is provided which comprises a casing having a fluid passage, a valve seat member disposed in the fluid passage, and a valve element housing with a valve element disposed therein. The valve seat member has a valve seat surface on an end surface facing downstream. The valve element housing is a discrete member separate from the valve seat member and detachably secured to a downstream end portion of the same. The valve element is displaceable between a closed position and an open position.

摘要： Provided is a check valve element enabling efficient supply of fluid while suppressing the occurrence of chattering. The check valve element is provided to be displaceable upstream and downstream in a downstream flow path extending downstream from a valve seat having an opening for introducing a fluid and is pressed against the valve seat by a pre-closing urging force applied thereto toward an upstream side. The check valve element has an arresting portion provided on an outer peripheral surface thereof, a sliding resistance imparting member support portion supporting a sliding resistance imparting member such that the sliding resistance imparting member slides along the wall of the downstream flow path when the check valve element is displaced upstream and downstream, and an urging member support portion supporting an urging member urged upstream so that the urging member urges the sliding resistance imparting member upstream, thereby causing the sliding resistance imparting member to increase in outer diameter while being arrested by the arresting portion.

摘要： A coupling member is provided that includes a filtration member provided in a fluid passage in a coupling body to divide the fluid passage into an upstream pre-filtration passage section and a downstream post-filtration passage section. The filtration member includes a cylindrical part extending in the direction of a longitudinal axis and having a filtration portion. The cylindrical part divides a downstream portion of the pre-filtration passage section and an upstream portion of the post-filtration passage section from each other in the radial direction of the cylindrical part. Further, the fluid passage has a dust collecting part extending in the direction of the longitudinal axis from the downstream portion to a position closer to a downstream opening than the filtration portion of the filtration member. The dust collecting part is closed at a downstream end thereof.
