Description
Technical field
This utility model is related to the improvement to two-bit triplet reversal valve, refers in particular to a kind of electromagnetic switch zero-leakage valve.
Background technology
With the continuous progress of science and technology, how requirement more and more higher of the industrial circle to valve gate technology ensures to be added
The crudy of work workpiece, the Proper Match of lathe, cutter, fixture and cutting fluid it is critical that.At a high speed with high accuracy machine
Bed can meet existing parts machining requirement substantially.But requirement of the workpiece degree of accuracy to fixture is very high.Fixture
Response speed, pressurize ability, commutation capacity requires also more and more higher therewith to valve.At present conventional two-bit triplet valve is cunning
Valve-type, the shortcoming of the two-position three-way valve of slide valve type：Guiding valve is divided into the reciprocating and class of swinging two.Reciprocatory slide valve has plane again
3 kinds of single valve clack, plane Double-clack and plunger type, plunger type guiding valve is widely used in hydraulic pressure and pneumatic means.Guiding valve makes pressure
The reciprocating motion of the pistons of cylinder, so constantly circulation, piston is just automatically continuously moved back and forth, if making spool actuation axle be in interposition
Put, then piston movement stops, the flap of planar mono flap guiding valve is produced because being acted on by larger pressure differential on sliding surface
Frictional force it is big, action is insensitive, easy to wear, and it is also because of the shortcoming in structure, it is impossible to adjust in the range of low discharge, thus works as
When plant equipment is run at low load, economy can be reduced；Plane Double-clack guiding valve increases a secondary flap, Flow-rate adjustment
Can and flap force-bearing situation be improved, but the development of factor still the limits valve industry such as internal leakage, frictional force is big.
The content of the invention
This utility model provides a kind of two-bit triplet electromagnetic switch zero-leakage valve, with solve to presently, there are internal leakage, rub
Wipe power big, action is insensitive, problem easy to wear.
This utility model is adopted the technical scheme that：Valve body is provided with three oil circuit holes：Fuel feed hole, oil outlet, oil leak hole,
Upper end cover is connected with valve body screw thread, and O-ring seal one and O-ring seal two are located between upper end cover and valve body, valve body activity
Valve element is connected with, valve element bottom is threadedly coupled with screw thread guide pillar, return spring is socketed in valve element bottom, valve element upper/lower terminal point
It is not provided with groove, upper and lower groove and is embedded with end-face seal ring two and end-face seal ring one, the annular boss of upper end cover bottom respectively
Contact with the end-face seal ring two at the top of valve element, bottom end cover is threadedly coupled with body base, there is suction between bottom end cover and valve body
Coiled electrical magnet, has end face sealing ring between the sucked type electric magnet top and valve body.
This utility model carries out end face seal to realize the version of commutation function using magnet control valve element, commutation
Valve element using the seal form of end face sealed nylon ring, more perfectly controls whole piece oil circuit completely, has abandoned the interior of conventional spool valves
Leakage, the defect such as service life is short；Pilot control factor instead of gas control by automatically controlled, i.e., replace cylinder or other gas with electric magnet
Controlling the commutation of hydraulic operated valve, magnet control valve element has stroke short to dynamic form, and thrust is big, is quick on the draw, and control is reliable, makes
The characteristics of using life-span length, while being especially optimized to major parts such as valve element and valve bodies and setting for the structure of hydraulic operated valve
Meter, had both simplified structure, and processing and assembly difficulty are reduced again so that hydraulic operated valve not only commutates flexibility and reliability, and carries significantly
High its service life, it is ensured that the zero leakage functional realiey of whole piece oil circuit.

Stricture of vagina connects, and O-ring seal 1 and O-ring seal 28 are located between upper end cover 6 and valve body 3, and in valve body 3 valve is connected with
Core 5, the bottom of valve element 5 is threadedly coupled with screw thread guide pillar 4, and return spring 10 is socketed in the bottom of valve element 5, the upper/lower terminal of valve element 5 difference
It is provided with groove, upper and lower groove and is embedded with end-face seal ring 2 12 and end-face seal ring 1, the convex annular of the bottom of upper end cover 6 respectively
Platform is contacted with the end-face seal ring 2 12 at the top of valve element 5, and bottom end cover 1 is connected with the bottom thread of valve body 3, in bottom end cover 1 and valve body 3
Between have sucked type electric magnet 2, have end face sealing ring 11 between the sucked type electric magnet top and valve body 3.
The empty connection external hydraulic dynamical system of fuel feed hole, oil outlet connection external executive component, oil leak hole connection dynamical system
System fuel tank, valve core reset dynamical system includes return spring 10, and threaded guide rod 4 is connected to valve element 5 and guide penetrates fuel feed hole
In the range of oil circuit, with the axially reciprocating of valve element 5, valve element is to complete commutation function to be oriented to electromagnetic valve gravitation.
