Abstract
Official abstract text for this publication.
Gate valve ( 1 ) with a valve casing ( 4 ) and a closing body ( 3 ) arranged longitudinally movably in the valve casing ( 4 ). An inlet channel ( 5 ) and an outlet channel ( 6 ) are formed in the valve casing ( 4 ). The closing body ( 3 ) via longitudinal movement cooperates with a valve seat ( 8 ) formed in the valve casing ( 4 ) and hence opens and closes a hydraulic connection between the inlet channel ( 5 ) and the outlet channel ( 6 ). The inlet channel ( 5 ) and the outlet channel ( 6 ) are each formed as a spiral.
First claim
Opening claim text (preview).
What is claimed is: 1. A gate valve ( 1 ) with a valve casing ( 4 ) and a closing body ( 3 ) arranged longitudinally movably in the valve casing ( 4 ), wherein an inlet channel ( 5 ) and an outlet channel ( 6 ) are formed in the valve casing ( 4 ), wherein the closing body ( 3 ) via longitudinal movement cooperates with a valve seat ( 8 ) formed in the valve casing ( 4 ) and hence opens and closes a hydraulic connection between the inlet channel ( 5 ) and the outlet channel ( 6 ), characterized in that the inlet channel ( 5 ) and the outlet channel ( 6 ) are each formed as a spiral, and wherein a continuous bore ( 12 ) is formed in the closing body ( 3 ), wherein the continuous bore ( 12 ) is hydraulically connected to the inlet channel ( 5 ) so that the end faces ( 13 , 14 ) on each side of the closing body ( 3 ) are loaded with a hydraulic pressure of the inlet channel ( 5 ). 2. The gate valve ( 1 ) according to claim 1 , characterized in that the hydraulic connection comprises a peripheral groove ( 30 ) formed on the closing body ( 3 ). 3. The gate valve ( 1 ) according to claim 1 , characterized in that the flow cross-section through the hydraulic connection is 1.2 to 1.5 times the flow cross-section through the inlet channel ( 5 ). 4. The gate valve ( 1 ) according to claim 1 , characterized in that the spiral forms of the inlet channel ( 5 ) and outlet channel ( 6 ) run over 360° of the periphery of the closing body ( 3 ). 5. The gate valve ( 1 ) according to claim 1 , characterized in that a further outlet channel ( 6 b ) is formed in the valve casing ( 4 ), wherein the closing body ( 3 ) via longitudinal movement cooperates with a further valve seat ( 8 b ) formed in the valve casing ( 4 ) and hence opens and closes a further hydraulic connection between the inlet channel ( 5 ) and the further outlet channel ( 6 b ), wherein the further outlet channel ( 6 b ) is formed as a spiral. 6. A waste heat recovery system ( 100 ) with a circuit ( 100 a ) conducting a working medium, wherein the circuit ( 100 a ) comprises, in the flow direction of the working medium, a pump ( 102 ), an evaporator ( 103 ), a bypass valve ( 1 ), an expansion machine ( 104 ) and a condenser ( 105 ), wherein a bypass line ( 106 ) is arranged in parallel to the expansion machine ( 104 ) and wherein the bypass valve ( 1 ) controls the mass flow of the working medium to the expansion machine ( 104 ) and to the bypass line ( 106 ), characterized in that the bypass valve ( 1 ) is a gate valve ( 1 ) according to claim 1 . 7. The waste heat recovery system according to claim 6 , characterized in that the hydraulic connection comprises a peripheral groove ( 30 ) formed on the closing body ( 3 ). 8. The waste heat recovery system according to claim 6 , characterized in that the flow cross-section through the hydraulic connection is 1.2 to 1.5 times the flow cross-section through the inlet channel ( 5 ). 9. The waste heat recovery system according to claim 6 , characterized in that the spiral forms of the inlet channel ( 5 ) and outlet channel ( 6 ) run over 360° of the periphery of the closing body ( 3 ). 10. The waste heat recovery system according to claim 6 , characterized in that a further outlet channel ( 6 b ) is formed in the valve casing ( 4 ), wherein the closing body ( 3 ) via longitudinal movement cooperates with a further valve seat ( 8 b ) formed in the valve casing ( 4 ) and hence opens and closes a further hydraulic connection between the inlet channel ( 5 ) and the further outlet channel ( 6 b ), wherein the further outlet channel ( 6 b ) is formed as a spiral.
