Abstract

The invention discloses an opening-adjustable pre-feeding adjusting valve device for powder. The device comprises a swing cylinder, a valve core, a spindle, a baffle assembly, a support frame, an adjusting screw, a surface mount component (SMC) gas circuit unit, a positioner, a marking peg and a scale range pole; the spindle is connected onto a valve shell in a penetrating manner; the swing cylinder is arranged on a cylinder fixed support; one end of a cylinder shaft is connected with the positioner through a positioning piece, the SMC gas circuit unit is arranged on the positioner through a gas circuit unit support, and the other end of the cylinder shaft is connected with one end of the spindle through a square sleeve; the support frame is arranged on the valve shell; the adjusting screw is in threaded connection with the interior of an inner bore of the spindle after penetrating through the support frame; the inner side wall of the valve core is connected with the baffle assembly; and the baffle assembly is driven through the rotation of the adjusting screw to horizontally move to change the opening size of a valve. The device is compact in structure; the adjusting screw turns into linear motion from rotary operation, so that adjustment is convenient and adjusting precision is high; and the opening of the valve is adjusted according to different working conditions, and therefore, a more stable material flow is provided.

Description

technical field [0001] The invention relates to the technical field of cement production equipment, in particular to a powder pre-feeding regulating valve device with an adjustable opening. Background technique [0002] In the cement production process, the quantitative, stable and continuous batching of powder is very important, which directly affects the quality of cement and energy consumption; the powder material flows out through the gas activation chamber, and then flows through gate valve, pneumatic flow valve, air After the chute, it enters the metering equipment, and finally enters the bucket elevator. [0003] In the production process, the feeding amount can be set through the instrument, the valve is opened at a corresponding angle, and the powder material after gas activation flows into the metering equipment. The metering equipment compares the load code obtained by the sensor with the set value, and passes 4~ The 20mA output signal adjusts the opening of the ...
