Description
Technical field
This utility model is related to solenoid valve market, the Direct Action Type high-pressure solenoid valve of specifically a kind of big orifice.
Background technology
It is domestic for the high-pressure solenoid valve product of big orifice at present, typically using pilot-operated type（Discharging type）Structure, that is, be powered
When, electromagnetic force opens pilot valve, upper chamber's rapid pressure drop, forms low high pressure reduction, fluid around valve element
Pressure promotes valve element to move up, and valve is opened；During power-off, guide's bore closure, inlet pressure is fast by by-pass prot for spring force
Fast chamber close valve member around shape be pilot valve open after, low high pressure reduction under formation, Fluid pressure promotion closure member to
Lower movement, closes valve.Guide electromagnetic valve has latus rectum larger, using the higher feature of pressure, but electromagnetic valve response speed compared with
Slowly.
Direct driving type electromagnetic valve arrangement, i.e., when solenoid valves, solenoid produces electromagnetic force and valve element is inhaled from valve seat
Rise, valve is opened；During power-off, electromagnetic force disappears, and spring handle valve element is pressed on valve seat, valve closing.Direct-acting electromagnetic valve has
Fast response time, it is the characteristics of flow resistance is little but typically small using direct-acting electromagnetic valve product latus rectum at present, using pressure typically compared with
It is low；
The fuel system of certain Satellite Attitude rail electromotor is controlling, electromagnetic valve to be proposed as follows will by electromagnetic valve
Ask：Latus rectum is required greatly, using pressure height, fast response time, little flow resistance, light weight, simple structure, reliability height etc..Therefore it is traditional
Direct Action Type or guide electromagnetic valve can not all meet requirements above, need a kind of new electromagnetic valve to meet certain Satellite Attitude rail
The use requirement of electromotor.
The content of the invention
This utility model patent solves a series of requirements that appearance rail electromotor is proposed to electromagnetic valve, there is provided a kind of big logical
The Direct Action Type high-pressure solenoid valve in footpath.Electromagnetic valve of the present utility model adopts direct dynamic structure, and latus rectum is big, and fast response time is used
Pressure is high.
The Direct Action Type high-pressure solenoid valve of this big orifice, it is characterised in that including valve body, coil trim, coil, spring,
Valve element, valve seat and O-ring seals, are coaxial integral structure, and electromagnetic valve top is valve body, and valve body upper end is medium inlet connection
Screw thread；Solenoid is wound with the middle part of valve body on border, is coil trim on the outside of solenoid, spiral shell of the coil trim by top
Nail is connected with valve body, and wire is drawn by solenoid by coil trim side, and at wire outlet irrigates asphalt mixtures modified by epoxy resin
Fat is by wire fixation；Valve body lower portion is connected using flange arrangement screw and valve seat, and adpting flange is sealed using O shapes
Circle sealing, is inlaid with airtight and watertight padding in the middle part of valve seat；Valve inner is provided with valve element, and valve element top is provided with spring, by spring
Initial pretightning force, valve element is pressed on valve seat, valve element upper end adopts O-ring seals and valve seal.
The control method of the Direct Action Type high-pressure solenoid valve of this big orifice, using bi-bit bi-pass direct dynamic structure, energization is opened
Open, power-off is closed；Fluid media (medium) is flowed into from above valve body, is flowed out from below valve seat；
With reference to rear accompanying drawing 1, when solenoid 3 is not powered on, initial precompression and medium pair that valve element 6 is subject to spring 5 downward
The airtight and watertight padding being embedded on the downward pressure of valve element, with valve seat 8 produces seal pressure, so as to medium has been enclosed in valve element
Portion；
After solenoid is powered, the magnetic conductor parts such as magnetic field, valve body 1, coil trim 2, valve element are produced around it
The band that will be magnetized under the action of a magnetic field is magnetic, while magnetic flux flows through them simultaneously forms a closed-loop path, valve element is in magnetic flux
Under effect, overcome spring force and pressure medium to be drawn to upwards and fit with valve body, valve element is opened, and medium enters valve seat, from valve seat
Lower section is flow in an interior collar aperture, so as to define the path of fluid；
After solenoid power-off, the magnetic field of generation disappears, and magnetic flux decays to rapidly the suction of its generation and is less than spring force
Afterwards, valve element is moved downwardly to fit with the sealing inserts of valve seat under spring force, and valve element is closed, so as to close fluid
Path.
When electromagnetic valve is not powered on, medium has been enclosed in valve core inside, and valve element mainly receives the initial precompression of spring and medium pair
The downward pressure of valve element；The initial precompression of spring, meets the required pressure of seal spool, general not too large；Medium pair
The pressure of valve element is the anchor ring product × pressure medium of valve element upper end wall thickness, and the area is less, and medium is acted on to the pressure of valve element
It is less, when valve element upper end wall thickness t very littles, can effectively reduce medium and act on and give valve element area, therefore medium is downward to valve element
Pressure is less, so as to, under high-pressure medium, valve element is remained able to by electromagnetic force adhesive.
This utility model compared with prior art, its remarkable advantage：
1st, latus rectum is big, high using pressure, and sustainable conduction time is long, thus offer big flow that can be continual and steady is situated between
Matter；
2nd, action response speed is fast（≤10ms）, the solenoid of the electromagnetic valve is larger, and spool sectional area also compares
Greatly, very big electromagnetic attraction can be produced, thus response speed is very fast；
3rd, using inner pressed valve core structure, that is, when being not powered on, medium is enclosed in valve core inside, the medium pressure downward to valve element
Power very little, therefore can work at elevated pressures；
4th, thermal diffusivity is good；Winding wire is directly wound on valve body, increased area of dissipation, and body cavity has medium straight
Connected, coil heat can be taken away, so that coil temperature is greatly lowered, sustainable more than energization 1000s；
5th, using coaxial-type global design, simple structure, flow resistance are little, and reliable operation；
6th, outlet is can be directly mounted on the thrust chamber of appearance rail electromotor, is not only connected reliable, and is reduced thrust chamber
The cavity volume of head, is favorably improved the Pneumatic acceleration of thrust chamber and reduces cut-off impulse；
