Abstract
The utility model relates to a double-flow electric controlled valve driven by a motor, which is suitable for a fuel oil oiling machine. The utility model is composed of a control circuit, a motor, a driving mechanism, a double-flow valve core and a valve cavity, wherein, based on the requirement of the external control signal, the control circuit drives the motor to rotate in definite angle and then drives the double-flow valve core in the valve cavity to move to the corresponding position through the driving mechanism to shut off the flow and control the pass of the large flow or small flow.
Description
The utility model is a kind ofly to be used to control fluid with the electrically-controlled valve that two kinds of flows pass through, and is particularly useful for fuel charger, improves the flow control of the accuracy of measuring.
The used double fluid amount electrically-controlled valve of fuel charger is the leading type double-flow-rate electromagnetic valve at present, big flow, small flow is arranged and end three kinds of states.The leading type double-flow-rate electromagnetic valve mainly by electromagnetic coil, double armature, have guide's diaphragm of pilot hole, stage clip and valve pocket are formed, its opening and closing are mainly relevant with three factors of elastic force of the elasticity of fluid pressure differential, guide's diaphragm and stage clip, shut-in time is subjected to the influence of fluid pressure differential very big, range of working pressure is narrow, need certain this pressure of stream could proper functioning, it be big to flow this pressure loss.Because it is more to influence the factor of parameter, very tight to the material requirements of stage clip, guide's diaphragm, harsh to the processing technology requirement of pilot hole, valve pocket, armature, armature chamber, processing cost is very high.The gap of armature and armature chamber wall is very little, and impurity such as the iron filings in the fluid are magnetized easily and are stuck in stuck spool in the rank body cavity, and solenoid valve was lost efficacy, and electric current is increased and plays heat and burn out, and causes security incident.During solenoid valve conduction, electromagnetic coil is switched on always, consumes more electric power.
The purpose of this utility model provides a kind of double fluid amount electrically-controlled valve, reduces the requirement to material and machining accuracy, and the action of valve does not rely on hydrodynamic pressure, but directly provide by motor, avoid the stuck spool of impurity in the fluid, and the discontinuous work of motor, energy-saving and cost-reducing, increase safety coefficient.
The purpose of this utility model is achieved in that and adopts the power source of motor as the spool action, reduces spool action parameter and hydrodynamic pressure relation, makes the valve also can proper functioning when no hydrodynamic pressure.Driving mechanism is converted into the axial motion of spool with the rotation of motor, and driving mechanism has at least three stable operating points, makes spool stable and accurately be parked in and close under the control of circuit, on big flow and three positions of small flow.The structure of spool can be controlled fluid and pass through gear with big flow or two of small flows when opening.This electrically-controlled valve mainly is made up of control circuit, motor, driving mechanism, dual-flow valve core and valve pocket.Control circuit is according to the requirement of external control signal, and drive motor rotates a certain angle, and drives the dual-flow valve core by driving mechanism and moves to desired big flow, and the position of small flow or shutoff is to realize the control of fluid flow.
Adopt this mode, material, processing technology and hydrodynamic pressure are not all had special and harsh requirement, on the path that fluid is flowed through, do not have the less place of matching gap, do not have magnetic force, avoided the obstruction of impurity, thereby do not have the stuck possibility of spool; And can adopt low voltage DC motor, only the moment motor in the spool action just need rotate, and is energy-saving and cost-reducing, improved the golden performance of peace, improves life of product, solves double-flow-rate electromagnetic valve many disadvantages in actual applications well, reduces cost, and increases reliability.
