Connection is set, the butterfly valve includes butterfly plate, and butterfly plate top two sides are provided with fastening spigot, the air bag part activity and butterfly plate
Fasten spigot contact.
Further, the air bag part is set to groove part inner surface and forms hollow structure with groove inner surface, described
Hollow structure connectivity trachea device.
Further, the tracheae device includes the air inlet pipe for being filled with gas and the exhaust pipe for releasing gas,
Valve is provided on the air inlet pipe and exhaust pipe.
Further, the fastening spigot is the column to match with the groove part, and the fastening spigot surface is set
It is equipped with anti-skid structure.
Further, the anti-skid structure is helicitic texture or continuous link structure.
