Abstract
The invention discloses an electrolytic aluminium crust breaking cylinder feedback valve, which comprises a back-up ring (1), an O-shaped loop (2), a gland (3), a spring (5), a special-purpose seal (6) and a contact rod (7), wherein the O-shape loop (2) is installed inside the groove of the gland (3), which is fixed on a front cover (8) through the back-up ring (1); the spring (5) is installed inside a counter bore of the gland (3); the special-purpose seal (6) is connected with the contact rod (7) through a nut (4). After crust breaking by the cylinder is completed, the electrolytic aluminium crust breaking cylinder feedback valve will immediately sound a feedback signal so as to control the cylinder to rapidly withdraw, limit the residence time of a hammerhead in an aluminium liquid, detect the state of the hammerhead in the aluminium liquid and raise the purity of the aluminium liquid.
Description
Technical field
The present invention relates to a kind of electrolytic aluminum crust breaking cylinder feedback valve.
Background technology
Existing electrolytic aluminum crust breaking cylinder is the special-purpose cylinder that electrolytic aluminium factory uses; Its function is divided into the blanking crust breaking and goes out two kinds of aluminium crust breakings; During use; Pressurized air gets into cylinder through pipeline and drives the tup realization crust breaking that descends fast, finishes the back at crust breaking and makes the cylinder fast retractile through the switching-over of control reversing valve.Shortcoming is owing to can't monitor cylinder state; Can impact many unnecessary problems such as aluminium liquid purity,, must after the cylinder crust breaking finishes, send feedback signal at once for solving this type problem; The control cylinder fast retractile; The time that the restriction tup stops in aluminium liquid, detect tup in the state of aluminium liquid, improve the purity of aluminium liquid.
Summary of the invention
The purpose of this invention is to provide a kind of may command cylinder fast retractile, improve the electrolytic aluminum crust breaking cylinder feedback valve of aluminium liquid purity.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of electrolytic aluminum crust breaking cylinder feedback valve; Comprise back-up ring (1), O type circle (2), gland (3), spring (5), special-purpose sealing (6) and contact lever (7); Said O type circle (2) is installed in the groove of gland (3); Gland (3) is fixed on the protecgulum (8) through back-up ring (1), and spring (5) is installed in the counterbore of gland (3), and special-purpose sealing (6) is connected with contact lever (7) through nut (4).
When crust breaking cylinder moves down when carrying out crust breaking fast, because the effect of P1 and spring, valve position is motionless.
When crust breaking finished, piston slap contact lever (7) forced P1 to communicate with P2, and the transmitter that communicates with P1 sends the action of signal control reversing valve, lower chamber of air cylinder ventilation, cylinder rapid return.
A kind of electrolytic aluminum crust breaking cylinder of the present invention feedback valve can send feedback signal at once after the cylinder crust breaking finishes, the control cylinder fast retractile, and the time that the restriction tup stops in aluminium liquid, detect tup in the state of aluminium liquid, improve the purity of aluminium liquid.
Description of drawings
Fig. 1 is the structural representation of a kind of electrolytic aluminum crust breaking cylinder of the present invention feedback valve.
Among the figure: 1, back-up ring; 2, O type circle; 3, gland; 4, nut; 5, spring; 6, special-purpose sealing; 7, contact lever; 8, protecgulum;
Embodiment
As shown in Figure 1, electrolytic aluminum crust breaking cylinder feedback valve comprises back-up ring 1, O type circle 2, gland 3, spring 5, special-purpose sealing 6 and contact lever 7, and O type circle 2 is installed in the groove of gland 3; Gland 3 is fixed on the protecgulum 8 through back-up ring 1, and spring 5 is installed in the counterbore of gland 3, and special-purpose sealing 6 is connected with contact lever 7 through nut 4, and the pressure of P1 is 0.6MPa; The pressure of P2 is 0MPa, and the peak pressure of P3 is 0.6MPa, and this valve can be installed on the crust breaking cylinder protecgulum; Pressure P 1 communicates with source of the gas, pressure P 2 and atmosphere, and pressure P 3 communicates with the cylinder rod chamber; Move down fast when carrying out crust breaking at crust breaking cylinder, because the effect of pressure P 1 and spring 5, valve position is motionless; When the crust breaking end, piston slap contact lever 7 forces P1 to communicate with P2; The transmitter that communicates with P1 sends the action of signal control reversing valve, lower chamber of air cylinder ventilation, cylinder rapid return.
