Description
Technical field
The present invention relates to a kind of malleation bleed valve, belong to the performer of controlling pressurized machine and two-stage supercharging on the motor based on pulse-width regulated.
Background technique
Pressurized machine is that the waste gas inertia impulsive force that utilizes motor to discharge promotes turbine, the turbine impeller, and the air that the impeller force feed is sent here by the air-strainer pipeline makes it supercharging and enters cylinder.Technology is used to control exhaust gas pressure to be difficult for excessive solenoid valve all is switching mode before this, the effect of just playing switch makes the gas break-make discharge, but can not make the aperture controlled amount of bleed valve, the switching value of only making bleed valve can cause venting too fast, pressure reduction moment change is big, damages other mechanism's sensor.
Summary of the invention
The objective of the invention is to overcome switching mode bleed valve deficiency in use, realize the linear bleed valve of opening.
Technological scheme of the present invention is:
A kind of malleation bleed valve, comprise valve body, valve body is provided with the coil assembly parts, sensing unit, magnetic conductive part, the coil assembly parts comprise the coil that is arranged in the valve body, second joint of valve body one side and the 3rd joint and the electrode that is arranged on the valve body opposite side, sensing unit comprises the fixed support that is arranged in the valve body, be provided with plastic stent in the fixed support, be provided with through hole in the middle of the fixed support, plastic stent is provided with pore, magnetic conductive part comprises first joint that is arranged on opposite side in the valve body, be arranged on magnetic conductive tube and concentrating flux plate in the valve body, first joint is provided with the copper pin near in the end of sensing unit, be provided with spring between first joint and the sensing unit, spring housing is contained on the copper pin.
The pore that is provided with on the plastic stent in the sensing unit is the waist-shaped hole of a loop.
The centre of the plastic stent two ends pore in the sensing unit is provided with the silicone rubber pad.
Beneficial effect: the present invention has three joints, and first joint communicates with the 3rd joint during no electric circuit, and second joint communicates with the 3rd joint during energising.First joint is to connect not pass through the preceding air of supercharging, and second joint is to connect through the later air of pressurized machine, and the 3rd joint is to export final controlling element to, is about to through the air after the compressed by being adjusted to needed controllable pressure behind this valve.During no electric circuit, sensing unit is subjected to the effect of spring force to seal the valve of second joint, and pressurized air is from pore to the three joints of first joint by sensing unit.When energising, the output voltage of controller is the PWM form, so EDM Generator of Adjustable Duty Ratio, different dutycycles acts on the different electromagnetic force of generation on the coil, sensing unit is subjected to the balance of making a concerted effort to reach of electromagnetic force, spring force and gas pressure, air pressure in the 3rd joint and presents linear output with the variation of dutycycle because the release of second joint reduces.
The unlatching controlled amount of bleed valve of the present invention changes slowly the gas pipeline internal pressure differences, protects the normal use of other sensor.Switch valve is made simple, and quilt easy to control generally adopts.

Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
A kind of malleation bleed valve, comprise valve body 20, valve body 20 is provided with the coil assembly parts, sensing unit 7, magnetic conductive part, the coil assembly parts comprise the coil 1 that is arranged in the valve body 20, second joint 8 of valve body 20 1 sides and the 3rd joint 2 and the electrode 3 that is arranged on valve body 20 opposite sides, sensing unit 7 comprises the fixed support 13 that is arranged in the valve body 20, be provided with plastic stent 15 in the fixed support 13, fixed support 13 hollows, plastic stent 15 is provided with pore 12, magnetic conductive part comprises first joint 4 that is arranged on opposite side in the valve body 20, be arranged on magnetic conductive tube 9 and concentrating flux plate 10 in the valve body 20, first joint 4 is provided with copper pin 5 near in the end of sensing unit 7, be provided with spring 6 between first joint 4 and the sensing unit 7, spring 6 is sleeved on the copper pin 5.
The pore 12 that is provided with on the plastic stent 15 in the sensing unit 7 is the waist-shaped hole of a loop.
The centre of the plastic stent 15 two ends pores 12 in the sensing unit 7 is provided with silicone rubber pad 14.
As shown in the figure: when electrode 3 is not switched on, sensing unit 7 is subjected to spring 6 power and the common effect of pressurized air to the right, silicone rubber pad 14 is sealed the pore of second joint 8 on the plastic stent 15, air after the compression enters from first joint 4, through plastic stent 15 pores 12 to the 3rd joints 2, this moment, the pressure at the 3rd joint 2 places was identical with first joint, 4 places.
Electrode 3 is switched on, coil 1 energising can produce electromagnetic force, the magnetic line of force is subjected to magnetic conductive tube 9 and retrains with the enclosed cavity that concentrating flux plate 10 forms, all through 7 effects of 4 pairs of sensing units of first joint, be that effect that fixed support 13 is subjected to electromagnetic force drives plastic stent 15 and overcomes spring 6 power and pressurized air resistance to left movement with silicone rubber pad 14, when silicone rubber pad 14 leaves the pore of second joint 8, pressurized air in the 3rd joint 2 has part to flow out from second joint 8, causes the pressure in the 3rd joint 2 to reduce.Dutycycle increases electromagnetic force and strengthens, the compressed air pressure of the 3rd joint 2 outputs also changes thereupon, when dutycycle increases to maximum, fixed support 13 promptly moves to high order end, this moment, silicone rubber pad 14 left ends on the plastic stent 15 fully contacted with copper pin 5 on first joint 4, made silicone rubber pad 14 seal the endoporus of copper pin 5 fully, and first joint 4 is by complete closed, pressurized air in the 3rd joint 2 all flows out from joint 28 at this moment, and the pressure recovery in the 3rd joint 2 is to barometric pressure.Along with reducing of dutycycle, fixed support 13 is made a concerted effort pushing away by spring 6 and pressurized air and is moved right, and when silicone rubber pad 14 leaves copper pin 5, enters pressurized air again in the 3rd joint 2, and pressure rises.
The principle of this bleed valve adopts coil electricity to produce magnetic field, attracts the sensing unit motion, finishes the output of a threeway two-wire system.
Plastic stent easy deformation when mounted, so at mounting portion inserted shim 11, fastening indeformable when guaranteeing to install.
