Abstract
The utility model relates to a multichannel high-frequency switching valve. A sealing slide sheet which can automatically stretch to compensate abrasion loss is embedded in a rotary valve core. The multichannel high-frequency switching valve can be used for multichannel high-frequency fast switching.
Description
The utility model is a kind of multichannel switching valve.
Similarly switching valve has reciprocating type and rotary two kinds at present, because the restriction of sealing configuration, working life is short, flexibility is relatively poor and serviceability temperature is not high, and is therefore higher in Environmental Conditions (or medium) temperature, be difficult to realize frequent fast the switching when sealing requirements is stricter.
The purpose of this utility model provide a kind of seal reliable, go slick, the long service life valving of high frequency switching fast.
Principle of the present utility model and main structure feature:
The motion mode of this valve is a rotation mode.Thereby be embedded with telescopic slide plate on the spool, under the effect of spring, closely contact the flexible of compensate for wear amount, assurance sealing effect and running automatically with valve interior surface all the time.Slide plate can be straight sheet, axially with radially all should install and the two juxtaposition; Another kind is the closed ring slide plate, and simple form is cylinder or rectangular frame.
This switching valve can not considered the life problems of its sealing under quick high frequency switching state, cooperate suitable material can cover-temperature environment of 18-1200 degree centigrade.Switching channel quantity is unrestricted.But but also axial series layout use of switching valve layout.
In the accompanying drawing, Fig. 1 is the principle sketch of this device.Be embedded with telescopic slide plate (2) in the spool (1), slide plate (2) is adjacent to the internal surface of valve body (4) all the time under the effect of spring (3).Fig. 2, Fig. 3 are respectively cylindric and rectangular frame shape slide plates.
This switching valve can be made the most frequently used four-way switching valve by accompanying drawing.Drive unit is fixed on the valve two end cap, can adopt rotary cylinder or worm wheel gearbox.When the area that surface of contact encloses of slide plate and valve body during, do not collaborate between two groups of passages in the handoff procedure, and can realize the state that four-way all ends greater than channel cross-section.
Claims (3)
1, a kind of high frequency switching valve is made up of valve body, spool, slide plate, spring etc., it is characterized in that slide plate between spool and valve body, and is a part of in the spool groove, and spring is between spool and slide plate, and is a part of in spool bore.
2, high frequency switching valve according to claim 1 is characterized in that slide plate can be shapes such as straight sheet, cylindric, square frame shape, the slide plate containing spool of also can slotting.
3, high frequency switching valve according to claim 1 is characterized in that spring can use metal spring or the gas spring by rotating shaft and valve core inside passage.
