The model utility content:
The purpose of this utility model is in order to overcome above deficiency, a kind of flexible material flow control valve that can effectively control the unlatching of materials flow to be provided.
The purpose of this utility model is achieved like this:
The utility model flexible material flow control valve comprises the upper valve body that contains material feeding mouth, the following valve body that contains discharge port that is connected with upper valve body, be positioned at upper and lower valve body and upper and lower end and be separately fixed at flexible spool on the upper and lower valve body, be positioned at the outside and the rotating ring that be connected with flexible spool of flexible spool, the driving mechanism that motor power transmission and rotating ring are made it to rotate, motor can adopt direct current (d.c.) also can adopt AC motor, decides according to user's needs.
Above-mentioned flexible spool comprises flexible cylindrical shell, is connected to ring on the steel wire of flexible cylindrical shell upper, middle and lower portion, central ring, ring down, last ring, encircles and is separately fixed on upper valve body, the following valve body down, and central ring is installed on the rotating ring.
Above-mentioned flexible sleeve axon sectional shape is a frustoconic shape.
Above-mentioned rotating ring periphery has annular groove, driving mechanism is chain wheel driving mechanism or pulley transmission mechanism, thereby thereby chain wheel driving mechanism or pulley transmission mechanism comprise the driving sprocket wheel or drive pulley, tension sprocket or the idler that lay respectively in the transmission case respectively, are sleeved on the drive chain of the swivelling chute driven rotary ring rotation in driving sprocket wheel, tension sprocket, the rotating ring or are sleeved on the drivign belt that the annular groove driven rotary ring in drive pulley, idler, the rotating ring rotates.
The cam position-limit mechanism is arranged in the above-mentioned control valve, the camshaft in the microswitch case of being contained in that is subjected to that driving mechanism drives is arranged in the cam position-limit mechanism, have out, stop cam on the camshaft respectively, on the microswitch casing with open, stop the cam opposite position limit switch is arranged respectively.
Referring to Fig. 1～Fig. 5, during work, by manual operation button (or automatically control by automatic control system) actuating motor, by driving mechanism driven rotary ring forward or reverse, realize the open and close action of valve, the limit position of valve open and close is controlled by sensitive switch by cam mechanism, reaches the limit of the position and stops automatically.
The utility model has adopted flexible spool, open steadily flexibly, close and tightly do not leak material, axially installation dimension is little, and fault is low, and weight is lighter, effectively controlled the unlatching of materials flow, overcome the total card valve of rigid valve, leaked material, blanking (weighing) inaccurate shortcoming, can be widely used in the feed, batching, weighing, packaging system of industries such as metallurgy, chemical industry, chemical fertilizer, grain, food, feed, as the capital equipment of control materials flow.
