Claims

[Scope of Claim for Utility Model Registration] A valve body 2, which is formed in a valve body 1 in the shape of a disk and has a circular hole-shaped valve port 20 in the central part, is made of an elastic and flexible material such as a rubber material. It is installed so that liquid flowing in from an inlet 10 provided at one end of the box 1 passes through a valve port 20 of the valve body 2 and heads toward an outlet 11 provided at the other end of the valve box 1. In a constant flow valve, a downstream end wall surface 21 of a disk-shaped valve body 2 made of a flexible material and a valve body 1 supporting the end wall surface 21 are provided.
between the valve support surface 30 of the valve seat 3 provided on the valve port 2
1. A constant flow valve characterized in that a bypass-like flow path a is formed to communicate between the upstream side and the downstream side of the valve body 2 by bypassing the valve body 2. The bypass-shaped flow path a is connected to the valve support surface 3 of the valve seat 3.
A constant flow valve according to claim 1, wherein the constant flow valve is formed by a groove 32 formed at zero. 2. A constant flow valve according to claim 1, wherein the bypass-like flow path a is formed by a groove 22 formed in a downstream end wall surface 21 of a disc-shaped valve body 2 made of a flexible material.
