ABSTRACT:
The subject valve discharge system comprises a discharge valve member that includes a valve closure segment at an inlet end thereof for insertion in the discharge valve housing. It further includes valve connecting means at a discharge end thereof. The respective discharge valve member and the discharge valve housing together define a gap therebetween. The discharge elbow defines a flow passage therethrough and includes elbow inlet and outlet ends. The elbow inlet end includes elbow connecting means. Discharge valve mounting means are connected to the respective discharge valve member and the elbow connecting means, respectively. The valve mounting means is self-adjustable during use for axial movement in response to the axial movement of the discharge system which is responsive to the axial movement of the rotary drum filter. In this way, the gap setting is maintained at a substantially constant, fixed clearance.
