Description
Technical field
The utility model relates to a kind of direct-acting type belt spool position mechanical adjustment proportional throttle valve, particularly is applicable to the direct-acting type belt spool position mechanical adjustment proportional throttle valve equipment in the regulation of hydraulic system flow circuit.
Background technique
At present, the flow system flow major part in the existing oil hydraulic circuit is to adopt manually operated type to regulate the ratio amount of restriction, can not use process control machine automatically to control, the adoption rate throttle valve control flow that has, its defective is that precision and the linearity are low, repeated inaccuracy, and the position of spool can not mechanical adjustment.
Summary of the invention
The purpose of this utility model, provide a kind of direct-acting type belt spool position mechanical adjustment proportional throttle valve, it is the adjust flux working stability operation of adopting in the hydraulic circuit, when amplifier is not given the proportion electro-magnet current signal, spool is in closed condition under the effect of spring force, pressure oil enters filler opening and any hydraulic fluid port is all obstructed; Amplifier is during to the proportion electro-magnet current signal, the certain thrust of proportion electro-magnet generation overcomes spring force moves spool, the open valve filler opening is to the path of control port gradually, after spool moves a certain distance, pressure oil enters control port by the circular trough of spool, the electric current of proportion electro-magnet increases gradually, spool displacement distance increases gradually, then pressure oil strengthens gradually by the circular trough area of spool, the flow that then passes through increases gradually, when adjustable lever is regulated inward, initial tension of spring then increases, spool moves identical distance needs larger power, and the flow by the spool circular trough in the constant situation of electrical signal reduces, and realizes the purpose of the direct-acting type belt spool position mechanical adjustment ratio throttling in the hydraulic circuit.
The utility model direct-acting type belt spool position mechanical adjustment proportional throttle valve takes following technological scheme to realize: it is by valve body, oil outlet, filler opening, control port, spring seat, swivel nut, adjustable lever, preloading spring, Returnning spring, circular trough, spool, proportion electro-magnet, amplifier consists of, one side of valve body arranges respectively filler opening, control port and oil outlet, the oil circuit of filler opening is communicated with circular trough on the spool, one end Set scale electromagnet of valve body, the other end of valve body arranges swivel nut, device spool in the axial bore of valve body, circular trough is set on the spool, spool one end arranges spring seat, install Returnning spring between spool and the spring seat, one side of spring seat arranges preloading spring, preloading spring one end arranges adjustable lever, the adjustable lever device is in the swivel nut axial bore, and proportion electro-magnet one side arranges amplifier.When amplifier was not given the proportion electro-magnet current signal, spool was in closed condition under the effect of spring force, and pressure oil enters filler opening and any hydraulic fluid port is all obstructed; Amplifier is during to the proportion electro-magnet current signal, the certain thrust of proportion electro-magnet generation overcomes spring force moves spool, the open valve filler opening is to the path of control port gradually, after spool moves a certain distance, pressure oil enters control port by the circular trough of spool, the electric current of proportion electro-magnet increases gradually, spool displacement distance increases gradually, then pressure oil strengthens gradually by the circular trough area of spool, the flow that then passes through increases gradually, when adjustable lever is regulated inward, the power of preloading spring then increases, spool moves identical distance needs larger power, and the flow by the spool circular trough in the constant situation of electrical signal reduces, and realizes the effect of the direct-acting type belt spool position mechanical adjustment ratio throttling in the hydraulic circuit.
The effect of the utility model direct-acting type belt spool position mechanical adjustment proportional throttle valve is that compact structure is simple, easy to operate, the appearance and modeling volume is little, cost is low, working stability is reliable, and the linearity is good, and the ring that stagnates is little, repeatability is high, and the tool that is widely used in the regulation of hydraulic system flow circuit is regulated proportional throttle valve equipment.
