Abstract

Abstract A valve particularly adapted to be used in the bottom of a tank and particularly desirable for use in connection with food products because of the ease with which it may be disassembled and cleaned can be constructed utilizing a two part cylindrical housing having an inlet opening in one end of the housing. A movable poppet is located within the housing in such a manner that a handle attached to the poppet body and extending out through a diagonal slot in the housing may be moved in the slot so as to move a poppet head serving as a valve closure with respect to this inlet opening. Seals are carried by the poppet body so as to engage the interior of the housing in order to prevent leakage out around the handle.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 389 words
A valve which comprises: a two-part valve housing having a cylindrical housing body and end walls attached to said housing body at both of its ends, said housing having an inlet part and an outlet part, said parts fitting together between said ends, said housing including holding means for holding said iNlet and said outlet parts together, a round inlet opening in one of said end walls, said inlet opening being centered about the axis of said body, an outlet opening in the other of said end walls, a slot located in said housing body so as to extend around a part of said housing body in a diagonal path such that one extremity of said slot is located closer to said inlet opening than the other extremity of said slot, a poppet having a cylindrical poppet body, a closure head and a perforate connecting structure connecting said closure head and said poppet body, said closure head being of smaller dimension than said poppet body and being symmetrical about the axis of said poppet body, said poppet being movably located within said housing body so that the exterior of said poppet body is adjacent to the interior of said housing body and so that said closure head is located on the end of said poppet body closest adjacent to said inlet opening, said poppet being capable of being moved between the end walls of said housing, said closure head being capable of fitting against said end wall having said inlet opening during movement of said poppet body within said housing body so as to close and seal said inlet opening, a handle carried by said poppet body and extending outwardly of said housing body through said slot, said poppet being capable of being moved so as to open and close said inlet opening by moving said handle within said slot, and two separate body seal means, each of said seal means forming a seal between the interior of said housing body and the exterior of said poppet body, said seal means being located on opposite sides of said slot and extending completely around the interior of said housing body and the exterior of said poppet body so as to seal off said slot from the interior of said housing body at all times during the operation of said valve.
