Abstract
The utility model discloses a blanking control valve which comprises a body, a gate valve body, a drive device and a shaft. A gate arc board is arranged below the gate valve body. The gate arc board is connected with the shaft. The shaft is in connection with the drive device. The blanking control valve has only one shaft, so that the blanking control valve is simple in structure, accurate in controlling the valve to be opened and closed, long in service life, good in practicability and capable of generating good economic benefit and social effect.
Description
Technical field
The utility model relates to all kinds of source material delivery systems of industry such as metallurgy, mine, chemical industry, relates in particular to a kind of raw material falling control device.
Background technique
At present, existing blanking control valve has driving shaft and driven shaft in the general valve body, by the gear engagement, respectively be connected with the fan-shaped flashboard of a fan on the axle between the diaxon, drive driving shaft by drive unit, realize the open and close of valve, such as patent 200420109337.8 described blanking control valves.This type of control valve, although can realize folding, its structure is comparatively complicated, component are many, in case any damage in gear or two axles all can cause being difficult to work, exist working life short, the shortcoming that cost is expensive.
The model utility content
Goal of the invention: for the deficiencies in the prior art, it is more simple that the purpose of this utility model provides a kind of structure, the blanking control valve that working life is long.
Technological scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:
A kind of blanking control valve comprises body, gate valve body, drive unit and axle; Establish gate arc plate below described gate valve body, gate arc plate links to each other with axle; Described axle links to each other with drive unit.
Described drive unit is the Electrohydraulic push rod device, and it is fixed on the body by pusher bar support and push rod base plate, and described Electrohydraulic push rod device is provided with Electrohydraulic push rod, an end of Electrohydraulic push rod and crank chain connection, and the other end of crank links to each other with axle.
In the blanking control valve, the Electrohydraulic push rod device drives Electrohydraulic push rod and does the shift reciprocately motion, flexible forward and reverse rotation control by motor of Electrohydraulic push rod, Electrohydraulic push rod drives crank, the rotation of crank band moving axis, the gate arc plate that axle below connects is done the swing of several angle thereupon, the blanking port of control valve is opened or is closed, thereby to material stream pass through open, close or control.
Beneficial effect: compared with prior art, this blanking control valve only has an axle, and is simple in structure, can more accurate control valve open or close, long service life has good practicability, can produce good economic benefit and social effect.
Description of drawings
Fig. 1 is the structural representation of blanking control valve;
Fig. 2 is the right elevation of blanking control valve.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As illustrated in fig. 1 and 2, gate valve body 2 is arranged in the body 1, be fixed with pusher bar support 4 and push rod base plate 5 on the body 1, be fixed with the Electrohydraulic push rod device on this support and the base plate, this Electrohydraulic push rod device comprises motor, oil pump, hydraulic control valve, Electrohydraulic push rod 6 etc., one end of Electrohydraulic push rod 6 and crank 7 chain connections, the other end of crank 7 links to each other with axle 8, is connected with a fan brake door arc plate 9 on the axle 8, the blanking port that gate arc plate 9 can airtight blanking control valve.
During this blanking control valve work, start the Electrohydraulic push rod device, drive Electrohydraulic push rod 6 and move in the horizontal direction, thus the rotation of drive crank 7, the rotation of crank 7 can be with moving axis 8 again, and the gate arc plate 9 on the axle 8 rotates thereupon, and blanking port is opened, and material is passed through; When the needs throttle down, start the Electrohydraulic push rod device, driving Electrohydraulic push rod 3 is got back to original position and is got final product, flexible forward and reverse rotation control by motor of Electrohydraulic push rod 3.
This blanking control valve is only used an axle, and is simple in structure, can more accurate control valve open or close, long service life has good practicability, can produce good economic benefit and social effect.
