Technical field
The utility model relates to a kind of direct-acting triple proportional throttle valve, particularly is applicable to the direct action type proportional throttle valve equipment in the regulation of hydraulic system flow circuit.
Background technique
At present, flow system flow major part in the existing oil hydraulic circuit is to adopt the manually operated type adjust flux, can not use process control machine automatically to control, the adoption rate throttle valve control flow that has, its defective is precision, the linearity and repeated inaccuracy, can not play in use the effect of ratio throttling, the appearance and modeling volume is larger, and complex structure is heavy.
Summary of the invention
The purpose of this utility model, provide a kind of direct-acting triple proportional throttle valve, it is to adopt the reliable direct-acting triple proportional throttle valve of adjust flux working stability in the hydraulic circuit, when amplifier is not given the proportion electro-magnet current signal, spool is in opening state under the effect of spring force, pressure oil enters in the radial hole of valve pocket by filler opening, ring shaped slot by spool enters control port, when amplifier during to the proportion electro-magnet current signal, the certain thrust of proportion electro-magnet generation overcomes spring force moves spool, the cut-off valve filler opening is to the passage of control port gradually, control port and oil outlet passage are opened gradually, discharge the pressure of control port, realize the purpose of the threeway ratio throttling of filler opening and oil outlet and control port.
The utility model direct-acting triple proportional throttle valve takes following technological scheme to realize: it is by valve body, oil outlet, filler opening, control port, proportion electro-magnet, amplifier, spring, spool, valve pocket consists of, one side of valve body arranges filler opening, control port and oil outlet, the oil circuit of filler opening is communicated with ring shaped slot and the control port of the radial hole of valve pocket through spool, spring cavity volume and oil outlet are interconnected, the turnover of control port pilot pressure oil, valve body axially in valve pocket is set, be provided with spool in valve pocket is axial, ring shaped slot is set on the spool, between spool and the valve pocket spring is set, one end Set scale electromagnet of valve body, proportion electro-magnet one side arranges amplifier.When amplifier is not given the proportion electro-magnet current signal, spool is in opening state under the effect of spring, pressure oil enters in the radial hole of valve pocket by filler opening, ring shaped slot by spool enters control port, when amplifier during to the proportion electro-magnet current signal, the certain thrust of proportion electro-magnet generation overcomes spring moves spool, close gradually filler opening to the passage of control port, control port and oil outlet passage are opened gradually, discharge the pressure of control port, realize the threeway ratio restriction effect of filler opening and oil outlet and control port.
The effect of the utility model direct-acting triple proportional throttle valve is that compact structure is simple, easy to operate, the appearance and modeling volume is little, the valve body cost is low, working stability is reliable, the linearity is good, the ring that stagnates is little, and repeatability is high, is widely used in the direct-acting triple proportional throttle valve equipment in the regulation of hydraulic system flow circuit.
