摘要： A discharge valve unit 50 is attached to a fluid device including a housing 1 including a first reservoir 41 for liquid and a first valve mechanism 42 including a first discharge hole 45 provided in the first reservoir 41 and a first valve member 43 accommodated in the first reservoir 41 and configured to open and close the first discharge hole 45. The discharge valve unit 50 includes: a valve case 51 configured to be detachably attached to the housing 1 and including a second reservoir 52 for liquid configured to communicate with the first reservoir 41 when the valve case 51 is attached to the housing 1; and a second valve mechanism 53 disposed in the second reservoir 52 and including a second discharge hole 56 having a larger opening diameter than that of the first discharge hole 45 and a second valve member 54 accommodated in the second reservoir 52 and configured to open and close the second discharge hole 56. The second valve mechanism 53 includes a spring 57 configured to bias the second valve member 54 in a valve opening direction. When a pressure of the second reservoir 52 increases to a predetermined value, the second valve member 54 closes the second discharge hole 56 against a biasing force of the spring 57.

摘要： A valve device forming a portion of a ventilation flow channel of a fuel tank (T) includes a float valve (2), a case (3) housing the float valve (2), and an outside member (4) housing the case (3) and including an attachment portion (4g) to a fuel tank (T) side. One portion of a cylindrical seal member (7) fitted in a first through hole (3b) to communicate an inner portion to a second through hole (4b) is pinched between a top portion (3a) of the case (3) wherein the first through hole (3b) is formed, and a top portion (4a) of the outside member (4) wherein the second through hole (4b) communicating to an outside of the tank (T) is formed, and a lower end of the cylindrical seal member (7) becomes a valve seat (7e) of the float valve (2).

摘要： A backflow prevention apparatus 1 is provided with a check valve 10 and a float-type backflow prevention valve 20, these being installed in this order as one proceeds from upstream to downstream. The check valve 10 comprises a valve seat 15 that causes a location toward the float-type backflow prevention valve 20 and a location upstream therefrom in a wastewater drainage system to be placed in mutual communication; a valve member 14 that closes the valve at the valve seat 15 due to an upwardly directed restoring force and that opens the valve at the valve seat 15 as a result of being made to fall when the restoring force is overcome by a hydraulic head of wastewater flowing thereinto from a location upstream therefrom; and a restoring force exerting means 13 that exerts an upwardly directed restoring force on the valve member 14; wherein the components responsible for causing closure of the valve at the valve seat 15 by the valve member 14-which include the valve seat 15, the valve member 14, and the restoring force exerting means 13-are formed from metal(s). The float-type backflow prevention valve 20 comprises an annular valve seat 21 that causes a location downstream therefrom in the wastewater drainage system and a location toward the check valve 10 to be placed in mutual communication; a float 24 that rises in accompaniment to a rise in a water level of wastewater to close the valve at the annular valve seat 21 and that falls in accompaniment to a fall in a water level of wastewater to open the valve at the annular valve seat 21; a guide member 22 that guides movement of the float 24 in a vertical direction; and a constraining member 23 that constrains a lowermost position to which the float 24 can move.

摘要： A fluid flow control arrangement adapted to maintain a fluid within a containment area to a set fluid level. The arrangement includes a float device within a hollow chamber resting inside the fluid containment area in communication with a pivotally supported arm which in the raised position is adapted to close a valve arrangement to stop a flow of fluid from a supply inlet side through to an outlet side of the fluid control arrangement into the containment area and when said pivotally supported arm is in the lowered position is adapted to open the valve arrangement to allow a flow of fluid from the supply inlet into the containment area.
