Abstract
The utility model relates to a fast valve which mainly solves the problem that due to the fact that the position of an air cylinder valve on a piston shaft is difficult to adjust, the sealing performance cannot be ensured when an existing fast valve is used. The fast valve is characterized in that the air cylinder valve comprises an air cylinder end cover, a piston shaft is sleeved with the air cylinder end cover, a first through hole is formed in the piston shaft, the air cylinder end cover is provided with a second through hole perpendicular to the first through hole and capable of being communicated with the first through hole, and the first through hole and the second through hole are fastened through a pin roll to form air cylinder valve axial limitation. Due to the fact that the second through hole is formed in the air cylinder end cover, and the corresponding first through hole is also formed in the piston shaft, when the first through hole corresponds to the second through hole, the pin roll or a fastener can be used for fixing the through holes to achieve the purpose of adjustment, and the sealing performance and the service life of the fast valve are ensured.
