Abstract
The utility model discloses a novel two-position three-way normal-opened gas path electromagnetic control valve for automobile. A magnetism isolating sleeve, a fixed iron core and a fixed seat of the electromagnetic valve are sequentially welded into an integral structure; the fixed seat is externally provided with threads on which a base component is screwed; the integral structure is internally provided with a movable iron core and a spring plug connecting rod component; the outer end of the magnetism isolating sleeve is provided with internal threads on which a gas discharge component is screwed; and a gas discharge nozzle is arranged on the gas discharge component. When the novel two-position three-way normal-opened gas path electromagnetic control valve for automobile is used, the magnetism isolating sleeve, the static iron core and the fixed seat are in an integral structure, the structure is simple, the assembly is convenient, and the magnetic inductivity is highe compared with the traditional split structure; the assembly procedure is simplified, and the processing cost is reduced; the gas discharge component is screwed on the internal threads of the outer end of the magnetism isolating sleeve, and is used for adjusting the magnetic gap to enable the product to achieve the optimum performance.
Description
Technical field
The utility model relates to the solenoid valve of automobile with gas circuit control and gas circuit safety control, especially a kind of normal open gas circuit solenoid electric valve of two-position three way.
Background technique
At present the solenoid valve that uses on the automobile is because of its complex structure, the cost height, and the poor reliability life-span is short.Wherein old-fashioned solenoid valve structurally adopts split screw or riveted joint to connect, the component structural complexity and the precision that require are very high, so just make product increase processing cost, and it is maintainable poor, be unfavorable for that product survives in market competition, and each automobile main frame maker also should not adopt the solenoid valve of this kind structure; Because solenoid valve is to guarantee that by rubber it is bubble-tight, easy deformation in long-term the use causes solenoid valve fit dimension chain to change in addition, and it is big that magnetic gap (air gap) becomes, and tightness reduces, and gas leakage easily so just makes reliability of products and life-span reduce.
Summary of the invention
The purpose of this utility model is exactly in order to cut down finished cost, to improve reliability of products and life-span, proposing a kind of novel two-position three way normal open type gas circuit solenoid electric valve.
The technical solution of the utility model is for this reason, and a kind of automobile comprises the static iron core in the solenoid valve, moving iron core, magnetic shield, fixed base, spring, plug, connecting rod, base member with the normal open gas circuit solenoid electric valve of novel two-position three way.It is characterized in that: described magnetic shield, static iron core, be welded into a structural entity successively with reservation, fixed base is provided with screw thread outward, is rotary with base member on the screw thread; Be provided with moving iron core and spring, plug, linkage component in the structure; The outer end of magnetic shield is provided with internal thread, is rotary with exhaust component on the internal thread, and exhaust component is provided with exhaust nozzle.
Beneficial effect:
When using the utility model because magnetic shield, static iron core, fixed base are welded into a structural entity successively, simple in structure, easy to assembly, and permeability is divided body structure higher (because of there not being magnetic resistance) than tradition, so simplified assembly process, has reduced processing cost.
The outer end of magnetic shield is provided with internal thread and is rotary with exhaust nozzle, can adjust magnetic gap, makes solenoid valve reach minimum pick-up voltage, tightness and maximum airflow when assembling, makes product reach optimum performance.When solenoid valve used some cycles, its decreased performance or gas leakage can be regulated the exhaust nozzle magnetic gap again by this device, make it reach optimum performance, prolonged the working life of product.Can adjust magnetic gap because of it machining accuracy of component can correspondingly be reduced, reduce processing cost, be fit to produce in enormous quantities.
Because this solenoid valve is the normal open type, pressurized gas constantly flow to actuating device by its spool, impurity in the air-flow and greasy dirt and water have corrosion and destruction to spool, influential to tightness, gas leak phenomenon easily takes place, so require electromagnetic valve structure simple, dismounting easily, when breaking down, valve body can be disassembled and clean, regulate exhaust nozzle after ressembling again, can reach original performance requirement.
Description of drawings
Fig. 1 is the utility model assembly structure sketch.
Embodiment
As shown in Figure 1, before the solenoid valve assembling, at first just magnetic shield 7 is welded into one-piece element with static iron core 8, fixed base 4; And then and moving iron core 2, base member 5, exhaust component 1, spring 6, plug 10, connecting rod 9 be assembled into assembly together.This moment, suction port 12 and air outlet 13 communicated, relief opening 14 sealings; The starting stage solenoid valve is behind the fixed air pressure of drift, and gas 13 flows to actuating device by base member 5 from the air outlet.When need closed gas flow working stage, coil 3 work, moving iron core 2 downward and static iron core 8 adhesives drive plugs 10 downwards with 11 sealings of base gas port by connecting rod 9, reach and close the gas passageway; This moment, exhaust nozzle 14 communicated with air outlet 13, suction port 12 and air outlet 13 sealings, and the residual gas of actuating device can be discharged from the exhaust nozzle 14 of exhaust component 1.When outage, solenoid valve returns to the initialization state again.In above working procedure, can require to adjust rotation exhaust component 1 according to its technical performance, make solenoid valve reach throughput, tightness and the minimum starting resistor of regulation, make solenoid valve reach best operating point.
The outer end of magnetic shield 7 is provided with the closely-pitched internal thread, and fine thread is connected with exhaust component 1.The moving iron core 2 downward adhesives of solenoid valve when energising; And exhaust component 1 adopts the non-magnet material parts, when assembling can by the screw thread on the exhaust component 1 just or opposite spin regulate magnetic gap, make solenoid valve reach minimum pick-up voltage, guarantee tightness and maximum airflow, make product reach optimum performance.When solenoid valve used some cycles, its decreased performance or gas leakage can be adjusted magnetic gap by regulating exhaust component 1, make it reach optimum performance, have prolonged the working life of product.Can adjust magnetic gap because of it machining accuracy of component can correspondingly be reduced, its processing cost is just low, is fit to produce in enormous quantities.
