Standby manual gate valve, it is generally the case that hand operated gate valve is in the open state, and pneumatic chute power resources are compressed air or drum
Blower need to start compressed air or air blower, so having inside pneumatic chute when needing to convey powder in metering weighing bucket
Certain pressure, generally 4~5KPa.Since pneumatic chute is to convey powder diagonally downward, so conveying equivalent weight material
Consumed energy is only the 1/3~1/4 of screw conveyor, saves the energy, is used widely.
The cross section of pneumatic chute is mostly rectangular or rectangle, therefore the hand operated gate valve shape docked with pneumatic chute
Also be rectangular or rectangle, hand operated gate valve by valve buckle, valve plate, screw rod, screw rod positioning seat, nut, handwheel, valve plate blend stop (17),
The parts such as directive wheel, sealing strip (18), sealing strip pressing plate (19), cover board (20) composition, structure such as Fig. 1 and with shown in 2；It is anti-
Only powder leaks, and sealing seems especially important.There is certain pressure inside when due to pneumatic chute work, and valve plate section is square
Shape, rectangular section sealing is not easy to realize, therefore is only made up using other measures；The sealing structure of existing hand operated gate valve
As shown in figure 3, sealing strip is foaming adhesive tape, sealing strip is compressed after valve plate again by sealing strip pressing plate with sealing strip pressing plate when installation
Point is welded on valve body, and the flexible deformation by the adhesive tape that foams is sealed, and is not easy to replace after foaming adhesive tape abrasion；As can be seen from Figure 4,
Valve plate rectangular section both sides sealing is bad, be easy leakage ash, to make up this defect, from figure 2, it is seen that top two sides added with cover board into
Row sealing, prevents dust from leaking outside, and the valve plate two sides gap Reng You, dust can enter manual gate valve top seal space, influence silk
Stem nut rotation, and dry friction occurs with foaming adhesive tape when valve plate moves up and down, easy to wear, service life is shorter, this outgoing
Maintenance after raw abrasion is complex, greatly increases downtime, reduces working efficiency.
