Embodiment
Below in conjunction with accompanying drawing 1, the utility model two-position five-way hydraulicchange-over valve is further described.
As shown in Figure 1, two-position five-way hydraulicchange-over valve, comprises spool 1, front cover 3, valve pocket 5, spring 8, rear end cover 12, control port 13 and return opening 17, and control port 13 is arranged on front cover 3, and return opening 17 is arranged on rear end cover 12; Also comprise front swivel nut 4, rear thread sleeve 11, threeway 6 and baffle ring 10, front swivel nut 4 is fixedly connected with front cover 3, be preferably bolt to connect, front swivel nut 4 is threaded connection in the front portion of valve pocket 5, and threeway 6 is socketed in the middle part of valve pocket 5, and threeway 6 arranges baffle ring 10 below, rear thread sleeve 11 is threaded connection the rear portion at valve pocket 5, by rotating rear thread sleeve 11, promoting baffle ring 10 and threeway 6 being expressed on the flange upwards of valve pocket 5 periphery, having three filler openings 14,15,16 in the circumference of threeway 6.
Spool 1 comprises path section and large footpath section, and large footpath section is divided into two ends, and one end is connected with path section, the other end and path section away from, be provided with groove, for holding spring 8 in the section end, large footpath away from path section.The cross sectional area of path section is 2 ~ 4:10 with the cross sectional area ratio of large footpath section, and that is, the work area ratio of spool 1 both sides is 6 ~ 8:10, is preferably 8:10 here.
In order to reduce the resistance that commutates, improving the sensitivity of selector valve commutation, the large footpath section circumference of spool 1 is provided with multiple balancing slit 7, be preferably 4 balancing slits.
Spool 1 is arranged in the common space formed of front cover 3, front swivel nut 4 and valve pocket 5, seal respectively by the seal ring that the seal ring 2 that front cover is arranged, spool 1 large footpath section are arranged, control port 13 is arranged on front cover 3, controls oil and is entered in the enclosed space that jointly formed by spool 1, front cover 3, front swivel nut 4 and valve pocket 5 by this control port 13.
Valve pocket 5 adopts machining to be made, valve pocket 5 inner hollow.The periphery of valve pocket 5 front and rear is all provided with screw thread, for being threaded with front swivel nut 4 and rear thread sleeve 11 respectively.The part having circumference to give prominence to below of front threads, and form valve pocket 5 periphery flange upwards, for the end face location of threeway 6 on valve pocket 5, sealed by seal ring 9 between threeway 6 interior edge face and valve pocket 5 outer circumferential face.The middle part of valve pocket 5 offers multiple through hole, inner for the hydraulic oil in threeway 6 being incorporated into valve pocket 5.
Rear end cover 12 inner hollow, rear end cover 12 also has path section and large footpath section, and the endoporus Spielpassung of its path section and valve pocket 5, is sealed by seal ring.The diameter of bore of path section is greater than the endoporus of large footpath section and the diameter of return opening 17, therefore forms an annular step in section junction, path Duan Yu great footpath, for holding spring 8 and carrying out spacing to spring 8.Rear end cover 12 large footpath section circumferentially has multiple countersunk screw holes, is fixedly connected with rear thread sleeve 11 by screw.
The each part of hydraulicchange-over valve is 170mm in the overall dimensions of selector valve circumference, and the overall dimensions on hydraulicchange-over valve length direction is 350mm.
During work, when control port 13 does not pass into control oil, because of the elastic force effect of spring 8, the large footpath section of spool 1 is pushed to front swivel nut 4 by elastic force, at this moment the multiple through hole on valve pocket 5 and the fluid conducting in threeway 6, fluid enters return opening 17 by the internal holes of rear end cover 12, and now oil circuit is at utmost unimpeded.When control port 13 has passed into control oil, the path section that the pressure controlling oil promotes spool 1 end cap 12 is backward drawn close, and the through hole little by little large footpath section of spool 1 blocked on valve pocket 5, as long as control the pressure size controlling fluid well, just can control the size of through hole on the large footpath section shutoff valve pocket 5 of spool 1, control the uninterrupted of work fluid in threeway 6 thus, now oil circuit remains conducting.When the pressure of the control oil of control port 13 is enough large, the large footpath section of spool 1 is pushed to and is close to the path section of rear end cover 12, at this moment the through hole on spool 1 large footpath section complete shutoff valve pocket 5, the passage that threeway 6 inner fluid enters valve pocket 5 is truncated, return opening 17 does not have fluid, and now oil circuit is thoroughly closed.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the present utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
