Fully sealed electric flapper valve

Abstract

The invention belongs to the technical field of valves for powder or mixed material discharge control, in particular to a fully sealed electric slide valve. Fully sealed electric flapper valve, including a valve body and a driving device, the driving device is connected to the valve body; the upper end of the valve body is provided with an upper sealing body, the plugboard installed in the valve body is connected to one end of the rack, and the other end of the rack is connected to the rack through a pulley. The driving device is connected; the upper end of the flashboard is at the same level as the sealing strip of the upper sealing body, the inner side wall of the valve body at the lower end of the flashboard is provided with a rubber strip, and the side of the valve body through which the flashboard passes is provided with felt. The existing flapper valve cannot isolate the powder. The present invention provides a fully sealed electric flapper valve for powder or mixed material discharge control, which ensures that the flapper is in a stationary or moving state, so that the felt can be tightly connected with the felt. The insert plate contacts to prevent powder leakage and has good sealing performance.

Description

technical field [0001] The invention belongs to the technical field of valves for powder or mixed material discharge control, in particular to a fully sealed electric slide valve. Background technique [0002] At present, there are many types of gate valves in my country, including manual gate valves, pneumatic gate valves, hydraulic gate valves, and electric gate valves. Among the valves for controlling the discharge of powder or mixed materials, the pneumatic slide valve cannot solve the problem of controlling the amount of feeding. At present, the screw drive is commonly used, but the use of screw drive has a high failure rate, and the screw needs to be replaced frequently, and the sealing The effect is not good, and the environmental protection requirements cannot be met. [0003] Therefore, there is a need for an electric gate valve with a simple structure that can realize full sealing. Contents of the invention [0004] Purpose of the invention: [0005] The objec...
