The control lever 35 is rotatably connected to one side of the flow control opening 34 so as to move the flow control opening 34 back and forth in the axial direction of the valve body 31. The forward and backward movement of the flow regulating device 34 may be made in the form disclosed in Korean Utility Model Registration Application No. 20-2003-0037809 (hereinafter referred to as "first application") filed by the present applicant. In the forward and backward operating configuration of the flow regulating device 34 disclosed in this application, one end of a cylindrical regulator (not shown) is fixed to the lower end of the adjustment lever 35 in a right angle, and this regulator ( Not shown) is rotatably installed on the valve body 31, the other end of the adjuster (not shown) is disposed adjacent to the flow regulator 34, the other end of the adjuster (not shown) Coupling protrusion (not shown) protruding from the center eccentric position is formed, the flow rate control 34 is provided with a coupling groove (not shown) to which the engaging projection (not shown) of the adjusting body (not shown) is coupled to a portion adjacent to the other end of the adjusting body (not shown). When the control lever 35 is rotated forward and backward, the control body (not shown) fixed to the lower end of the control lever 35 is rotated so that the engaging projection (not shown) of the control body (not shown) is eccentrically rotated, By the eccentric rotation of the coupling protrusion (not shown), the flow control mechanism 34 connected to the coupling protrusion (not shown) is operated forward and backward. On the other hand, the forward and backward configuration of the flow control mechanism 34 of the present invention is described above. The present invention is not limited to the prior application, provided that the flow rate adjusting device 34 can adjust the supply flow rate of the beer introduced by moving back and forth on the inner diameter surface of the connector 20 by the control lever 35. Changes will be possible.

As such, when the flow control mechanism 34 moves back and forth on the inner diameter surface of the connector 20 by the control lever 35, the cone of the inclined portion 21 and the flow controller 34 of the connector 20 is moved. The gap between the outer circumferential surface is adjusted at an appropriate interval, and the draft beer flowing from the beer supply pipe 10 passes through the gap space between the adjusted flow regulator 34 and the connector 20 so that the inner flow path of the valve body 31 is Flows into 31a. That is, as the user directly manipulates the control lever 35 to appropriately adjust the gap space between the flow regulating device 34 and the connector 20, the user desires the supply flow rate of the draft beer flowing into the valve body 31. There is a feature that can be adjusted as appropriate.

On the other hand, the flow regulating opening 34 is a pair of beer inlet hole (34a) is formed symmetrically through each other from the outer peripheral portion one side surface to the center of the back surface, the pair of beer inlet hole (34a) is a flow control opening It is formed inclined with respect to the axis | shaft of 34. By the structure of the beer inflow hole 34a of this flow control opening 34, the supply flow volume passes through the clearance gap between the flow control opening 34 and the connector 20. This controlled draft beer is partially introduced into the open inner flow passage 31a of the valve body 31, and the rest of the draft beer passes through the beer inlet hole 34a of the flow regulator 34, and then the valve body 31 By flowing into the open inner flow path (31a) of the), unlike in the prior art, it is possible to prevent the beer supply flow is suddenly fluctuated, thereby suppressing the generation of vortices in the supply flow to smooth the supply flow of the draft beer .

The operation of the present invention configured as described above will be described below.

First, by rotating the control lever 35 in the front-rear direction, the flow control device 34 is advanced on the inner diameter surface of the connector 20 (mode to reduce the supply flow rate of the supplied beer) or backward (the supply flow rate of the supplied beer) Mode) to adjust the gap between the outer diameter surface of the flow regulating device 34 and the inner diameter surface of the connector 20 at appropriate intervals. Then, in order to draw the draft beer, When the handle is pulled backward, the piston 32 moves forward to open the internal flow path 31a of the valve body 31, so that a negative pressure is applied to the discharge port 31b side of the valve body 31, The draft beer is introduced from the beer reservoir (see FIG. 1) to the inner diameter surface of the connector 20 through the beer supply pipe 10, and the beer introduced in this way is controlled by the control lever 35. And the opening and closing block through the gap between the connector 20 It flows into the internal flow path 31a of the valve body 31 opened by the burr 33 and the piston 32, and is taken out through the discharge port 31b of the valve body 31.

At this time, a part of the draft beer passing through the gap space of the connector 20 and the flow regulating device 34 is introduced into the open inner flow path (31a) of the valve body 31, the rest of the flow regulating device (34) After passing through the beer inlet hole (34a) of the inlet into the open internal flow path (31a) of the valve body 31, unlike the prior art it can prevent the beer supply flow is sharply fluctuated, thereby It is characterized by suppressing the generation of vortices to smooth the flow of draft beer.

That is, conventionally, draft beer flowing into the internal flow path of the cock valve is directly introduced into the internal flow path of the valve body after passing through the gap between the flow control port and the connection port, and the supply flow of beer is rapidly changed, causing vortex flow. This occurs badly, due to this there is a disadvantage that the supply flow of beer is not made smoothly, but the present invention is a draft beer flowing through the gap between the flow regulator and the connector portion of the internal flow passage 31a of the valve body 31 ) Flows through the beer inlet hole (34a) of the flow control port 34 and then flows into the internal flow path (31a) of the valve body 31, the supply flow of beer is naturally continued, the supply flow Vortex generation in the bed is minimized to optimize the generation of bubbles, and the draft beer flows more smoothly, making draft beer very easy. It is made of features.

The present invention as described above, by smoothing the supply flow of the draft beer supplied to the internal flow path of the cock valve assembly, there is an effect that it is easier to take out the draft beer and optimize the foaming.

In the above, the present invention has been shown and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiment, and those of ordinary skill in the art to which the present invention belongs, without departing from the spirit of the technical idea of the present invention described in the utility model registration claims below. Various changes can be made.
