Description
Technical field
The utility model is related to a kind of controller for opening and closing of piston electromagnetic valve, specifically a kind of piston electromagnetic valve
Pilot valve device.
Background technology
Magnetic valve is, with the industrial equipment of Electromagnetic Control, direction, flow, the speed of medium to be adjusted in industrial control system
Degree and other parameters.Magnetic valve can coordinate different circuits to realize expected control, and the precision that controls and flexibility
Can ensure, wherein dynamic iron core needs frequently to move back and forth the opening and closing for realizing magnetic valve, in dynamic iron core as core component
In reciprocatory movement, due to there is air chamber between dynamic iron core and fixed core, during magnetic valve quick pick-up, plenum interior can be situated between
Matter compression cause cannot adhesive, need quickly to discharge the gas in air chamber, existing structure is to beat installing hole at dynamic iron core center,
Side is opened air drain and realizes exhaust, and this kind of structure directly reduces the core area of dynamic iron core, have impact on magnetic valve power.It is existing in addition
Have the needle that dynamic iron core top is installed, its during magnetic valve valve opening, because needle and dynamic iron core are without interaction force
, that is, needle is freely to hang, and there is certain space between needle and dynamic iron core, thus cause valve opening process
It is middle to there is one section of backlash that dynamic iron core rises and needle does not and then rise, during how increasing dynamic iron core valve opening
Effective travel and increase core area be always those skilled in the art research object.
The content of the invention
The utility model realizes that little structure is high-power, core area big, the piston electromagnetism of effective travel length there is provided one kind
The pilot valve device of valve.
A kind of pilot valve device of piston electromagnetic valve includes the dynamic iron core and fixed core of valve core spring connection, dynamic iron core one
There is air chamber between end and fixed core, the dynamic iron core other end is provided with the needle of control piston electromagnetic valve opening and closing, described needle one
In the installing hole that end is placed in dynamic iron core, the other end is socketed with back-up ring, back-up ring connection installing hole；Between described back-up ring and needle
It is provided with the needle spring of valve needle laminating dynamic iron core.The pilot valve device of this kind of structure between back-up ring and needle by setting
There is the needle spring of valve needle laminating dynamic iron core, realize dynamic iron core adhesive, during magnetic valve valve opening under spring force,
Jing overcomes gravity needle is moved upwards and the laminating dynamic iron core that automatically resets, and counteracts valve opening gap, increases effective row of valve opening
Journey.Certainly needle, to moving downward, is separated with dynamic iron core during closed electromagnetic valve, but can be automatically replied after separating.It is resulting
Technique effect is the enhancing of magnetic valve valve opening ability, and coil power is reduced, and valve opening pressure reduction increases, and volume reduces and energy-conservation.
The central axial pore for being provided with insertion of described dynamic iron core, pore connection air chamber installs valve core spring in one end, separately
Needle is installed as installing hole in one end.Described needle is provided with steam vent or air drain.The air hole structure of this kind of insertion coordinates
Steam vent or air drain on needle, forms the air flue of effectively connection, has abandoned the air drain knot of dynamic iron core side in traditional structure
Structure, considerably increases dynamic iron core cross-sectional area, and electromagnetic valve coil volume can be reduced on original power level, reduces energy
Consumption, it is cost-effective.
In order to realize that Quick air-discharge back-up ring is provided with more than one air channel, increase the sensitivity of magnetic valve opening and closing.Institute
One section of installation valve core spring of the pore stated, another section of installation needle, centre is provided with one section of connecting hole, and the aperture of connecting hole is less than peace
The aperture of one section of needle of dress, realizes that needle forward type is installed, and reaches the technical purpose of Fast Installation.
The utility model is fitted the needle spring of dynamic iron core by being provided with valve needle between back-up ring and needle, is realized dynamic
Iron core adhesive, during magnetic valve valve opening under spring force, has overcome gravity needle is moved upwards and the patch that automatically resets
Dynamic iron core is closed, valve opening gap is counteracted, increases the effective travel of valve opening, realize that coil power is reduced, valve opening pressure reduction increases, volume
Many advantages, such as reduction and energy-conservation.
