Abstract

Provided is a valve device into which a cone type venturi for a flow measurement and valves are integrated. According to the present invention, the venturi cone is formed in venturi path in the lower portion of the main body, and then valve path is formed thereafter. According to the present invention, efforts for adjusting heights between both of pressure taps during connecting of valves and flow measurement parts are not required and installation time and costs of installation could be decreased drastically. Also, the possibilities of leakage as well as manufacturing costs also could be reduced by integrating valves and flow measurement parts into a one-body valve device.

Claims

1. A cone type venturi integrated valve device comprising,

a main body 10 constructed of stainless steel;

a venturi path 12 which is formed in the main body 10 by penetrating in a horizontal direction, and including a hole 120 toward bottom, wherein a point of certain distance from the inlet side is defined as the first pressure point and the other point of certain distance from the outlet side is defined as the second pressure point P2;

a venturi cone 14 which is mounted between the first pressure point P1 and the second pressure point P2 in the venturi path 12, and including a first cone body 144 having a mild slope surface 142 faced to the first pressure point P1 and a second cone body 148 having a steep slope surface 142 faced to the second pressure point P2, and a fixing leg 154 extending (150) from the cone end of the first cone body 144 to the direction of center axis for a predetermined length, wherein the fixing leg 154 is bent(152) toward below and the bent end is inserted into the hole 120 of the venturi path 12 and attached by welding process, and wherein the venturi cone 14 acts to make the pressure of fluid at the second pressure point P2 relatively lower than that of first pressure point P1; and

a valve path 16 which is formed by penetrating through the main body 10 in a vertical direction with respect to the venturi path 12 so that the valve path 16 is connected with the first pressure point P1 and the second pressure point P2 of the venturi path 12, and including valves 162 for switching of fluid flowing through the valve path.

2. The cone type venturi integrated valve device of claim 1, wherein the second cone body 148 further comprises:

a center hole 149 extending from its cone end to its center axis direction.
