Abstract
Disclosed is a new electromagnetic valve assemblage structure which is characterized in that a magnet separator tube1, after being extruded and transformed, is embedded into a circular slot of a fixed iron piece2 and is axially fixed therein; a fixed iron piece4, after being extruded and transformed, is embedded into the circular slot of a valve core12 and is axially fixed therein; a valve body5 is circularly extruded and transformed to be sealed and tightened with the magnet separator tube1; a guide sleeve6 is extruded into the circular slot of the valve body5 and is fastened therein; clearance fits are arranged among the guide sleeve6, a pressing sleeve7 and the valve body5; a valve base8 and the valve body5are extruded to an upside-down cone so as to be connected. Adopting the above technical proposal, the components of the electromagnetic valve can be assembled through the transformation of various material, thus omitting the processes of machining screw threads and the circular slot for the seal ring; the assemblage structure simplifies machining and assemblage processes, reduces components and makes the components more compact and more reliable in connection, thus avoiding the disengagement of the screw threads, leakage as well as the aging of the seal ring; the assemblage structure improves sealing reliability after assemblage and ensures the whole performance of the braking system.
Description
Technical field
The utility model relates to a kind of solenoid valve, is specifically related to the solenoid valve assembly structure.
Background technique
At present popular in the world anti-block braking system of car (ABS) all adopts the switch of solenoid valve to realize automatic adjusting to brake-pipe pressure, prevent phenomenon such as sideslip that wheel lock up produces, whipping and drive the generation of skidding, with the control that realizes car brakeing stability or drive anti-skidding function.Because vehicle pressure in the braking line when braking is very high, particularly when emergency braking, therefore usually pressure can reach 14MPa-20Mpa, requires under the pressure at 30Mpa non-internal leakage and leak outside when pressure regulator is made, otherwise will influence the performance of whole ABS.This just requires must guarantee the reliable of sealability at the fit on of solenoid valve.At present a lot of solenoid valves adopt modes such as screw thread, welding or seal ring to assemble, although also can reach the effect of sealing, part number is many, processing and assembly technology complexity, also be easy to generate the problem of aging of thread looseness and leakage and seal ring, influence the braking system performance.
Summary of the invention
The purpose of this utility model is to provide a kind of electromagnetic valve assembly structure, uses this electromagnetic valve assembly structure to have the following advantages:
1. simplify processing of abs braking system and assembly technology, reduce the use of part, prevent the problem of aging of thread looseness and leakage and seal ring.
2. make part compact more, connects more reliably, improve the reliability of fitting tight performance, the overall performance of assurance braking system.
To achieve these goals, the technical solution adopted in the utility model is: a kind of electromagnetic valve assembly structure, comprise valve body, be provided with end filter screen, valve seat in the valve body successively, guide sleeve, gland, spool, spool are provided with moving iron outward, decide iron, moving iron and decide to be provided with spring between the iron, every magnetic, moving iron is provided with plunger tube with deciding the iron outside, and joins with valve body.
As a kind of improvement, described plunger tube extrusion-deformation embeds in the circular groove of deciding iron carries out axial restraint.
As a kind of improvement, carry out axial restraint in the circular groove of described moving iron extrusion-deformation embedding spool.
As a kind of improvement, described valve body annular extrusion distortion and magnetic tube sealing and fastening.
As a kind of improvement, described guide sleeve be squeezed into carry out in the circular groove of valve body fastening.
As a kind of improvement, adopt interference fit to be connected between described guide sleeve, gland and the valve body.
As a kind of improvement, the form that is squeezed into back taper between described valve seat and the valve body is connected.
The utility model is owing to adopt technique scheme, all adopt the material deformation method of various ways to assemble between each parts of solenoid valve, thereby avoided the circular groove of machining screw, seal ring, simplified processing and assembly technology, reduced part number, made part compact more, connect more reliable, avoid the problem of aging of thread looseness and leakage and seal ring, improved the reliability of fitting tight performance, guaranteed the overall performance of braking system.
