Embodiment Construction

[0011] like figure 1 As shown, a pneumatic pellet valve includes a valve body 1, a cover plate 2 inside the valve body 1, a bottom cover 3 located at the tail end of the valve body 1 and used to accommodate the cover plate 2, and a bottom cover 3 for driving the cover plate 2 to work. The driving mechanism 4, the driving mechanism 4 includes a cylinder 41 (not shown in the figure), a connecting rod 42 and a bracket 43, the bracket 43 is respectively connected to the cylinder 41 and the valve body 1, and the connecting rod 42 is connected to the working end of the cylinder 41 and the cover plate 2 . The cylinder body of the cylinder 41 is provided with a casing 11 for covering the cylinder 41, and the casing 11 prevents the cylinder 41 and other components of the control cylinder 41 from being exposed outdoors, so that the service life of the pellet valve can be extended.

Abstract

The invention discloses a pneumatic aggregate valve. The pneumatic aggregate valve comprises a valve body, a cover plate arranged in the valve body, a bottom cover positioned at the tail end of the valve body and used for storing the cover plate, and a driving mechanism for driving the cover plate to work; the valve body comprises a first valve plate with a feed port, and a second valve plate witha discharge port; the second valve plate is provided with an overflow port in the discharge port; the overflow port is inclined from the inner wall of the second valve plate to the discharge port; when the pneumatic aggregate valve is located in a closed state, particles in the valve body are pushed by the cover plate to flow out from the overflow port, so that the pneumatic aggregate valve solves the problem of incapability of closing the aggregate valve due to blockage of the bottom cover through arrangement of the overflow port; through replacement of manual operation by pneumatic operation, the personal safety and the operation convenience are improved; and the service life of the pneumatic aggregate valve is prolonged.

Description

technical field [0001] The invention relates to a valve, in particular to a pneumatic pellet valve. Background technique [0002] The traditional pellet valve, also called discharge valve, uses a hand wheel to drive the screw to rotate on the bracket to drive the valve stem at the lower end of the screw to move up and down, thereby driving the valve plug at the lower end of the valve stem to move up and down, so that the valve plug and the lower end The discharge port on the hopper cooperates to realize the on-off of the pellet valve. [0003] Since the particles are relatively small and the flow rate is relatively slow, and the cover plate of the pneumatic pellet valve has a certain thickness, when the pneumatic pellet valve is closed, the cover plate pushes the particles into the cavity of the bottom cover for receiving the top of the cover plate , as the number of particles increases, the cavity is filled with particles, and the cover plate cannot enter the cavity, resul...
