Abstract
A valve for permitting or precluding fluid communication between a fluid reservoir and a pipe. The inventive device includes a valve seat securable to a flange of the pipe. A support plate is adjustably positioned above the valve seat and mounts a fluid actuator thereover. A valve plate is coupled to the fluid actuator and can be axially moved relative to the valve seat to permit or preclude fluid transfer therethrough. The valve utilizes a pressure of the fluid within the reservoir to retain the valve plate against the valve seat in a closed condition.
Claims7
A axially moveable plate valve comprising:
- a substantially planar valve seat having a valve seat center aperture extending therethrough, said valve seat being securable to a flange of an associated drain pipe;
- a support plate supported in a spaced relationship relative to said planar valve seat, said support plate including a through-extending support plate center aperture;
- a valve plate positioned between said support plate and said valve seat and being selectively movable between an open position wherein said valve plate is spaced from said valve seat and a closed position wherein said valve plate covers said valve seat center aperture;
- actuator means to effect movement of said valve plate relative to said valve seat;
- and
- stanchion means for supporting said support plate in a spaced relationship relative to said valve seat, said stanchion means being adapted to permit easy adjustment of the spacing between said support plate and said valve seat to thereby adjust the spacing between said valve seat and said valve plate in said open position.
An axially moveable plate valve comprising:
- a substantially planar valve seat having a valve seat center aperture extending therethrough, said valve seat being securable to a flange of an associated drain pipe;
- a support plate supported in a spaced relationship relative to said planar valve seat, said support plate including a through-extending support plate center aperture;
- a valve plate positioned movably between said support plate and said valve seat for selectively covering said valve seat center aperture;
- and
- actuator means to effect movement of said valve plate relative to said valve seat;
- wherein said support plate includes a plurality of through-extending stanchion apertures extending circumferentially thereabout, and said valve seat includes a plurality of through-extending stanchion apertures extending circumferentially thereabout;
- and further comprising a plurality of threaded stanchions extending through said stanchion apertures;
- and a plurality of flange securing nuts engaged to said threaded stanchions for capturing said valve seat and said flange together in an abutting relation;
- and a plurality of support plate securing nuts engaged to said threaded stanchions to adjustably secure said support plate relative to said valve seat.
