| titleOfInvention | Split seat gate valve |
| abstract | A gate valve assembly is disclosed which has two body housing members with coaxial through passages which are connected together in end-to-end relation. The housing members have a gate slot and a seat portion slot located beneath the gate slot. Resilient sealing means are located between the body housing members and are compressed by the opposed housing members to form a liquid-tight seal along the sides of the valve. Two resilient valve liners are fitted within the housing members, each has a body with a cylindrical through passage and a generally cylindrical outer surface which engages within the through passage of the housing member. The body has a planar front face and a seat portion which extends downwardly from the body and increases in thickness as it extends from the body. The valve liners are adjacent one another within the housing member such that the planar front faces of the valve liners are adjacent and in contact with one another and the seat portions are compressed within the seat portion slots to produce a tight seal along the bottom of the valve. A packing chamber formed by the two housing members is located above the valve liners and is filled with a packing material compressed by a packing compressor to form a tight seal around the gate. An imperforate gate is slidable through the gate slot between a valve open position and a valve closed position wherein the gate is interposed between the valve liners to prevent any fluid flow. The packing material, the side sealing means, and the seat portions for a liquid-tight seal in both the valve open and valve closed positions. The seat portions extend to the bottom of the valve such that particles trapped between the seat portions may be expelled from the valve between the seat portions. |
