Description
Technical field
The invention belongs to injector valve body technique fields, and in particular to a kind of novel two-position three-way valve.
Background technique
In high pressure co-rail system fuel injector and natural gas injector, common hydraulic control mode is disengaging oil throttling at present
The mode in hole controls the raising and lowering speed of plunger, realizes the open and close of plunger, this fuel feed hole oil outlet controlling party
In formula, the flow of fuel feed hole directly affects the closing velocity of control plunger, and the plunger of major diameter has lesser closing velocity, together
When opening speed also can be relatively slow, so the opening and closing speed of usually major diameter plunger injector is difficult to meet quick response
It is required that meanwhile, the machining process for passing in and out oilhole is more complex, special precise machining equipment and hydraulic milling apparatus are needed,
Cause the manufacturing cost of product higher.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of novel two-position three-way valves.
The present invention is achieved through the following technical solutions:
A kind of novel two-position three-way valve, including solenoid valve, triple valve, valve block and threeway spring, the component are respectively positioned in shell,
Solenoid valve is connect by electromagnet spring with armature, and solenoid valve and triple valve connectivity part are equipped with control ball, is powered by electromagnet
The spring force for generating electromagnetic force and electromagnet spring controls armature raising and lowering, to make armature that control ball be driven to be transported
Dynamic, the triple valve is compacted in shell by clamp nut, and gasket is equipped at compression, is set between the triple valve and shell
There is pressure accumulation chamber, the first oil duct, ring cavity and the first oil pocket are equipped in triple valve, the second oil pocket is equipped in valve block, is set on the shell
There are plunger upper part oil duct, fuel feed hole, the first oil return hole and the second oil return hole, fuel feed hole to be connected to pressure accumulation chamber, triple valve passes through ring
Chamber is connected to the first oil pocket, the second oil pocket, threeway valve chamber and plunger upper part oil duct.
Further, the triple valve is intracavitary is equipped with threeway spring, and valve block is close to triple valve by the effect of threeway spring, when three
When the intracavitary pressure of port valve is lower than certain value, the high pressure oil in ring cavity pushes valve block to move downward.
Further, the control ball is oriented to equipped with ball, and armature is oriented to by ball and is connect with control ball.
The beneficial effects of the present invention are: improving the sound of the control cavity pressure variation of plunger part by two-bit triplet principle
Speed is answered, because major diameter plunger moves the larger flow of needs above and below, by the control of triple valve ring cavity, three can be effectively improved
The speed of the raising and lowering of port valve cavity pressure and the inflow and outflow amount for providing larger high pressure oil guarantee the larger movement of plunger
Speed finally improves the response speed of nozzle mechanical part, promotes the injection of common rail system oil atomizer and natural gas injector
Response characteristic, while the cost of goods manufactured also reduced.

Specific embodiment
A kind of novel two-position three-way valve 6 of the present invention is further described below with reference to embodiment.
Attached drawing 1,2 is a kind of specific embodiment of the invention.A kind of novel two-position three-way valve of the invention, including solenoid valve 1,
Triple valve 6, valve block 7 and threeway spring 8, the solenoid valve 1, triple valve 6, valve block 7 and threeway spring 8 are located in shell 15, electricity
Magnet valve 1 is connect by electromagnet spring 2 with armature 3, and solenoid valve 1 and 6 connectivity part of triple valve are equipped with control ball 5, passes through electromagnet 1
It is powered and generates spring force control 3 raising and lowering of armature of electromagnetic force and electromagnet spring 2, so that armature 3 be made to drive control ball 5
It is moved, the triple valve 6 is pressed in shell 15 by clamp nut 19, and gasket 20, the threeway are equipped at compression
It is equipped with pressure accumulation chamber 11 between valve 6 and shell 15, is equipped with the first oil duct 12, ring cavity 13 and the first oil pocket 14, valve block 7 in triple valve 6
It is inside equipped with the second oil pocket 16, the shell 15 is equipped with plunger upper part oil duct 9, fuel feed hole 10, the first oil return hole 18 and second time
Oilhole 21, fuel feed hole 10 are connected to pressure accumulation chamber 11, and triple valve 6 realizes ring cavity 13 and the first oil pocket by the up and down motion of valve block 7
14, the second oil pocket 16, threeway valve chamber 17 are connected to or disconnect with plunger upper part oil duct 9.
Further, threeway spring 8 is equipped in the threeway valve chamber 17, valve block 7 is close to triple valve by the effect of threeway spring 8
6, when the pressure in threeway valve chamber 17 is lower than certain value, the high pressure oil in ring cavity 13 pushes valve block 7 to move downward.
Further, the control ball 5 is equipped with ball guiding 4, and armature 3 is connect by ball guiding 4 with control ball 5.
A kind of novel two-position three-way valve of the invention, electromagnet 1, which is powered, generates the spring force control of electromagnetic force and electromagnet spring 2
3 raising and lowering of armature processed, the up and down motion of armature 3 directly drive the raising and lowering of control ball 5, when controlling the rising of ball 5,
Pressure decline in first oil pocket 14, causes the pressure in threeway valve chamber 17 to decline in this way, the pressure of 9 the inside of plunger upper part oil duct
Quick pressure releasing is realized by control ball 5, and rate of pressure release obviously increases in such plunger upper part oil duct 9, by plunger upper part oil
The jet element that road 9 controls starts opening movement.
Conversely, control ball 5 moves downward to form ball sealing under the action of electromagnet spring 2 after electromagnet 1 powers off, this
Shi Santong valve block 7 and triple valve 6 are in separated position, and high pressure oil flows into the second oil pocket 16, threeway by the ring cavity 13 of triple valve 6
Valve chamber 17 and plunger upper part oil nozzle top oil duct 9, because the circulation area of high pressure oil in ring cavity 13 is larger, so that these three intracavitary pressures
Power rapid increase, the jet element that plunger upper part oil duct 9 controls begin to shut off movement.
High pressure oil enters pressure accumulation chamber 11 by fuel feed hole 10, and the high pressure oil in pressure accumulation chamber 11 enters three by the first oil duct 12
The ring cavity 13 of port valve 6, usual valve block 7 are tightly attached to triple valve 6 by the effect of threeway spring 8, when the pressure in threeway valve chamber 17 is low
When certain value, the high pressure oil in ring cavity 13 will push valve block 7 and move downward, and triple valve 6 passes through pad by clamp nut 19
Piece 20 forms sealing after compressing between shell 15 and gasket 20, after controlling the rising of ball 5, final pressure accumulation chamber 11 and threeway valve chamber
High pressure oil in 17 is flowed out from the gap after the control rising of ball 5 to be returned by the first oil return hole 18 and the second oil return hole 21 again
Oil.
