Abstract
Official abstract text for this publication.
Provided is a fluid control valve capable of stabilizing fluid control characteristics. In a fluid control valve including: a valve housing and a valve seat member which include an inflow passage and a discharge passage, and a valve body that is configured to be brought into contact with and separated from the valve seat member and that forms an inner seal portion and an outer seal portion together with the valve seat member. At least one convex portion whichprojects into a space inside the valve housing formed between the inner seal portion and the outer seal portion.
First claim
Opening claim text (preview).
1 . A fluid control valve, comprising: a valve housing; a valve seat member attached to the valve housing, the valve housing and the valve seat member being formed with an inflow passage and a discharge passage, the valve seat member being disposed between the inflow passage and the discharge passage; and a valve body that is configured to be brought into contact with and separated from the valve seat member and that forms an inner seal portion and an outer seal portion together with the valve seat member, wherein at least one convex portion projects into a space inside the valve housing formed between the inner seal portion and the outer seal portion. 2 . The fluid control valve according to claim 1 . wherein the convex portion is separated from a facing member in a valve closed state. 3 . The fluid control valve according to claim 2 , wherein the convex portions are formed in both the valve body and the valve seat member. 4 . The fluid control valve according to claim 3 , wherein the convex portion formed in the valve body and the convex portion formed in the valve set member face each other. 5 . The fluid control valve according to claim 1 , wherein the convex portion is formed in an annular shape. 6 . The fluid control valve according to claim 2 , wherein the convex portion is formed in an annular shape. 7 . The fluid control valve according to claim 3 , wherein the convex portion is formed in an annular shape. 8 . The fluid control valve according to claim 4 , wherein the convex portion is formed in an annular shape.
