Abstract
The invention relates to a rotary four-way fluid reversing valve with two spiral grooves. The rotary four-way fluid reversing valve comprises a valve body and a valve plug, wherein the interior of the valve body is a cylindrical hollow cavity and the valve plug is arranged in the hollow cavity; four holes communicated with the hollow cavity are symmetrically distributed on the valve body; the rotary four-way fluid reversing valve is characterized in that the valve plug is a cylinder body, two through parallel through holes vertical to the axis of the valve plug and four symmetrical blind holes vertical to the central axis of the through holes are formed in the side surface of the cylinder body, and the two spiral grooves capable of rotating at 180 degrees in the same rotation direction are formed along the cylinder surface by taking the four blind holes as a reference. The rotary four-way fluid reversing valve with the two spiral grooves is simple in structure, low in machining precision requirement, simple in manufacturing, low in cost and long in service life, and is not worn easily, and reversing is implemented only by rotating the valve plug.
Description
Technical field
The present invention relates to a kind of fluid reversing device, particularly relate to a kind of double spiral groove rotary four-way fluid diverter valve.
Background technique
At present, known four-way fluid selector valve is made up of valve body, spool, valve gap, end cap and drive unit, valve body is arranged symmetrically with four holes, spool processes circular groove, drive unit promotes spool and moves left and right, connect the corresponding aperture on valve body by the circular groove on spool, reach the object of fluid reversing.But this structure of reversing valve is complicated, require that machining accuracy is high, Sealing easily weares and teares, manufactures difficult, manufacture cost is large.
Summary of the invention
The object of the invention is to the defect overcoming above-mentioned prior art, provide a kind of structure simple, requirement on machining accuracy is low, manufactures simple, the double spiral groove rotary type four-way fluid diverter valve that cost is low.
The object of the invention is to be realized by following technical proposals:
A kind of double spiral groove rotary four-way fluid diverter valve, the spool comprising an inner valve body for cylinder type hollow cavity and be arranged in this hollow cavity, described valve body is symmetrically distributed with four holes communicated with hollow cavity, it is characterized in that: described spool is a cylindrical body, its column side face have two parallel and perpendicular to the through hole of valve core axis and perpendicular to symmetrically arranged four blind holes in through hole medial axis, with these four blind holes for benchmark, have two along cylndrical surface with rotation direction 180 degree of spiral chutes.
Through hole after hole on described valve body, blind hole and 90-degree rotation is coaxial.
Double spiral groove rotary type four-way fluid reversing valve arrangement of the present invention is simple, and requirement on machining accuracy is low, and manufacture simple, cost is low, and its spool only need rotate and just can realize commutation, not easy to wear, long service life.

Fig. 2 is the A-A cross-sectional view in Fig. 1;
Fig. 3 is the valve body cross-sectional view of four-way fluid selector valve;
Fig. 4 is the valve core structure schematic diagram of four-way fluid selector valve.
Embodiment
Below in conjunction with accompanying drawing, structure of the present invention is described.
Double spiral groove rotary type four-way fluid diverter valve of the present invention is mainly made up of valve body 3, the spool 4 be arranged in valve body, the valve gap 2 being arranged on valve body 3 two ends and end cap 5 and drive unit 6.The inside of described valve body 3 is a cylinder type hollow cavity, it has communicate with hollow cavity hole I, hole II, hole III and hole IV, these four holes are symmetrically distributed on valve body.Spool 4 is installed in valve body 3 inside, and described spool 4 external form is a cylindrical body, and first the axis of vertical spool processes two parallel through holes 7, more vertical two parallel through holes process the blind hole 8 of each processing four certain depths, and these four through holes are symmetrical arranged.Last with these four blind holes for benchmark, process two along cylndrical surface with rotation direction 180 degree of spiral chutes 9.Hole on above-mentioned valve body and the blind hole coaxial design after corresponding through hole 7 and 90-degree rotation.When drive unit 6 rotates, four holes on change valve just can realize communicating between two.
Shown in Fig. 1 during position, two spiral chutes form two fluid passages, connect hole I and hole IV, hole II and hole III respectively; After movable valve plug 4 90-degree rotation is with by drive unit 6, two through holes 7 in the middle of on spool 4 form two fluid passages, connect hole I and hole III, hole II and hole IV respectively.So just can realize the object of four-way fluid selector valve commutation.
Claims (2)
