Abstract
Abstract The present invention pertains to flow control valves as employed in a standard piping system. More specifically, the present invention provides a flow control valve offering features which makes it inexpensive to manufacture and especially to maintain. The present flow control valve means basically comprises a main valve portion having a central opening to which a valve cover plate is operably attached and upon which cover plate all of the working parts, including the valve seat, plug, plug guides, plug or valve stem, and plug actuating means are operably mounted whereby the entire flow control assembly can be readily removed from the valve body in a very efficacious manner while employing conventional tools and without requiring any particuaar expertise. The present invention also provides a flow control valve of a design which minimizes the extent of wear realized in most present day control valves due to the influence of the normal dynamic forces encountered.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
224 words
Flow control valve means comprising: a. valve body means having its ends adapted for connection in a piping system and being provided with an opening in one side thereof adapted to receive valve cover plate means to which valve seat means, valve plug means, and valve plug actuating means are operably connected when said flow control valve means is fully assembled; b. valve cover plate means adapted to mate and connect with the opening provided in said valve body means; c. valve seat means adapted to mate with said valve cover plate means and being provided with an orifice through which fluid is allowed to flow; said valve seat means being further defined in that it is also adapted to mate with the inside surface of said valve body means in an essentially fluid tight relationship when said valve cover plate means is operably affixed to said valve body means and said valve seat means being oriented in an in-line operable position; d. valve plug means operably connected to said valve cover plate means; and e. plug actuating means operably connected to said valve plug means and said valve cover plate means whereby fluid flows through the orifice in said valve seat means can be controlled upon regulating the relative position of said valve plug means to the orifice in said valve seat means.
Claim 2
Dependent Claim
224 words
Flow control valve means comprising: a. valve body means having its ends adapted for connection in a piping system and being provided with an opening in one side thereof adapted to receive valve cover plate means to which valve seat means, valve plug means, and valve plug actuating means are operably connected when said flow control valve means is fully assembled; b. valve cover plate means adapted to mate and connect with the opening provided in said valve body means; c. valve seat means adapted to mate with said valve cover plate means and being provided with an orifice through which fluid is allowed to flow; said valve seat means being further defined in that it is also adapted to mate with the inside surface of said valve body means in an essentially fluid tight relationship when said valve cover plate means is operably affixed to said valve body means and said valve seat means being oriented in an in-line operable position; d. valve plug means operably connected to said valve cover plate means; and e. plug actuating means operably connected to said valve plug means and said valve cover plate means whereby fluid flows through the orifice in said valve seat means can be controlled upon regulating the relative position of said valve plug means to the orifice in said valve seat means.
Claim 3
Dependent Claim
116 words
The control valve means of claim 1 further characterized in that: said valve plug means is further defined as comprising an extended portion of a size and configuration sufficient to mate with and close off the orifice provided in said valve seat means and extended shaft portions extending upward along the longitudinal axis of movement of said valve plug means; said shaft portions being provided with finned members extending radially outwards, which finned members served to stabilze said valve plug means when fluid is flowing over and around its enlarged portion and through the orifice provided in said valve seat means when said valve plug means and valve seat means are not in a closed position.
Claim 4
Dependent Claim
140 words
The control valve means of claim 2 further characterized in that: said plug actuating means is further defined as comprising flexible cable means operably connected at one end to the upstream extended shaft portion of said valve plug means, and cable guide means operably mounted upon said valve cover plate means and positioned essentially along the longitudinal axis of travel of said valve plug means and over which the other end of said flexible cable means passes to a position exteriorly of said valve cover plate means, and said valve cover plate means is further defined as comprising cable sealing means through which said flexible cable passes so as to prevent fluid leakage from within said valve body means along said flexible cable means at that point where said flexible cable means extends exteriorly through said valve cover plate means.
Claim 5
Dependent Claim
91 words
The control valve means of claim 3 further characterized as comprising: f. valve plug guide means mounted upon said valve cover plate means and through which the extended shaft portions of said valve plug means extends so as to restrict the motion of said valve plug means along a longitudinal axis essentially perpendicular to the plane defined by the orifice in said valve seat means whereby said valve plug means is allowed to reciprocate relative to the orifice in said vaLve seat means upon the operation of said plug actuating means.
