Patent ID: 8215609

Claim:
A flow control valve assembly with low noise, the flow control valve assembly comprising: a pipe having a through hole therein with a plunger guide formed on a lateral surface thereof; a plunger installed within the plunger guide of the pipe which is capable of moving upwardly and downwardly along the plunger guide, wherein the plunger consists of a lower head and an upper rod, and has a groove formed at an upper surface of the lower head and a flange part formed on a lower surface of the upper rod so that the lower head and the upper rod are capable of being separated from or coupled to each other to deliver a lengthwise movement of the upper rod to the lower head without delivering a rotational force of the upper rod to the lower head; a silicone wall installed on an inner surface of the through hole of the pipe to define a flow passage in the middle thereof, wherein the lower head is configured to have substantially the same width as a diameter of a circular cross section of the silicone wall which has a cylindrical shape, and wherein the lower head is installed perpendicular to a lengthwise direction of the silicone wall, and has a semicircular lower portion so as to evenly pressurize the silicone wall toward a center of the circular cross section of the silicone wall when the semicircular lower portion of the lower head is pressed toward the silicone wall, a clamping joint installed at an inlet of the through hole of the pipe to clamp the silicone wall to the through hole of the pipe; and a stopping joint installed at an outlet of the through hole of the pipe to prevent the silicone wall from being thrust out of the through hole of the pipe.
