초록 ▼

A noise abating plug for a fluid control valve includes a perforated sleeve that forms one end portion of the plug and a plurality of spaced apart perforated discs that extend between a hub portion of the plug and the inner wall of the sleeve portion. The perforations in the sleeve and in the multi-perforated discs form a varying number of restrictive passageways for the fluid under control as the plug is moved between its open and closed positions and thereby maintain the pressure reduction occurring at the perforated sleeve and perforated discs at values which minimize the noise created by the fluid as it flows through the valve.

대표청구항 ▼

A fluid control valve including a body having a fluid inlet passageway, a fluid outlet passageway, and a first seat means located between said passageways and defining with the latter a fluid flow path through said body, said valve also including a noise abating throttling plug arranged for movement along its axis and within said first seat means between closed and open positions, said plug comprising a second seat means which sealingly engages said first seat means to close said flow path when said plug occupies said closed position, a perforated throttling sleeve which moves axially within said first seat means, to open an increasing number of the perforations of said sleeve to said flow path, as said plug is moved from said closed position to said open position, and a plurality of perforated discs mounted within said sleeve in spaced relation along and substantially normal to the axis thereof, each of said discs extending completely throughout the cross-sectional area of said sleeve to cause the fluid passing through said sleeve perforations to pass through configurations of all of the perforations in said discs, which configurations vary as said plug is moved between said positions, whereby the fluid in said flow path passes through configurations of said sleeve and disc perforations which vary, as said plug is moved between said positions, to form varying restrictive fluid passageway combinations for the fluid in said flow path as necessary to corresponding vary the fluid pressure drops effected along said flow path while minimizing the noise created by the passage of said fluid along said flow path.
