High clean hot filling valve

Abstract

The invention discloses a high-cleanliness hot filling valve which comprises a valve seat, a valve body and a discharge guide seat, wherein a valve plug with a plurality of through holes is arranged in a cavity of the valve body; a sliding sleeve is arranged on the valve body in a sleeving manner; a driving device for driving the valve plug is arranged between the sliding sleeve and the valve plug; a guide flange with a bottle mouth sealing gasket is arranged on the discharge guide seat; the guide flange and the sliding sleeve are connected and make synchronous motion; a valve port matched with the valve plug is formed in the cavity; a feed port of the valve seat after valve plug and valve port separation, the cavity of the valve body, the through holes of the valve plug, the valve port and a discharge port of the discharge guide seat form a filling channel; a contact surface of the valve plug and the valve port forms a sealing surface of the filling channel; a reset device for allowing the valve plug moving up to push against the valve port again is arranged between the valve body and the sliding sleeve; an exhaust pipe is arranged below the valve body; and the exhaust pipe and an exhaust outlet formed in a side wall of the valve body form an air return channel. The hot filling valve has the advantages of simple structure, convenience in cleaning and no hygienic dead angle.

Description

technical field [0001] The invention relates to a hot filling valve, in particular to a high clean hot filling valve. Background technique [0002] The hot filling valve is an important component of the hot filling device. The quality of the hot filling valve directly affects the production efficiency of the hot filling production line, the quality of the filled product and the level of filling accuracy. At present, the commonly used hot filling valve is provided with a groove for accommodating a sealing ring on the valve core in the valve body, and the valve core and the inner wall of the valve body are sealed by the sealing ring. During the hot filling process, the filling product will inevitably infiltrate into the groove containing the sealing ring. During the cleaning process, the liquid accumulated in the groove is difficult to be completely removed, and there is a hygienic dead angle. In this way, when filling During the process, the remaining liquid will contaminate...

AI Technical Summary

Problems solved by technology

During the hot filling process, the filling product will inevitably infiltrate into the groove containing the sealing ring. During the cleaning process, the liquid accumulated in the groove is difficult to be completely removed, and there is a hygienic dead angle. In this way, when filling During the process, the remaining liquid will contaminate the inner wall of the valve with the reciprocating movement of the piston, thus affecting the quality of the filled product
