Abstract
The utility model relates to a full-bore sterile valve comprising a valve body, a valve deck, a driving device and a valve rod. The valve deck is installed on the valve body. A valve channel allowing mediums to flow through and a valve cavity communicated with the valve channel are arranged in the valve body. A valve clack enabling the valve channel to be opened or sealed is arranged in the valve cavity. One end of the valve rod penetrates through the valve deck, stretches into the valve cavity and is connected with the valve clack. The driving device is installed at the other end of the valve rod. The valve clack is assembled in the valve cavity in a sliding mode. The valve clack comprises a rubber valve clack body. An abutting block is embedded in the rubber valve clack body. The valve rod is connected with the abutting block. The rubber valve clack body comprises a sliding sealing portion in sealing fit with the inner wall of the valve cavity and a valve channel sealing portion enabling the valve channel to be opened or sealed. The sliding sealing portion is located in the valve cavity and can slide along the inner wall of the valve cavity. The valve channel sealing portion is in a cone shape, and correspondingly, a cavity body which the valve channel is matched with the valve clack in is a cone-shaped cavity body. The full-bore sterile valve has the advantages of being free from hygienic dead angles, convenient to clean, large in valve channel opening degree, larger in valve channel flow rate and long in service life of the valve clack.
