Automatic valve

Abstract

An automatic valve, which is able to automatically seal a pipe when a tap is removed from the pipe, is disclosed. The valve consists of a collar, a disc and an "X" shaped member. The collar defines a central hole and a male threaded portion at an outer periphery thereof to engage with a female threaded portioned portion at the outlet of the pipe. Two opposed protrusions extend from a side face of the collar. Each of the protrusions axially defines a pair of slots. The disc is shaped for being exactly received within the central hole of the collar. The "X" shaped member is formed of a pair of integrated and intersected arms and has four ends radially and respectively received within the slots. A stem integrally and perpendicularly extends from a crossover point of the arms to the disc through the central hole of the collar. In a preferred embodiment, the central hole of the collar is configured as a tapered hole and an outer periphery of the disc is shaped as a cone corresponding to the tapered hole of the collar.
