Abstract
The utility model relates to a miniature switch valve. The utility model comprises a valve body, a valve seat, sealing rings, a clamping ring, a sleeve, a screw plug, a valve core, a spring seat, a spring, a guide sleeve, an oil inlet and an outlet port, wherein, the sleeve is butted and pressed on the valve seat by the screw plug; the interior of a slot on the outer side of the valve seat is provided with the sealing ring; the sealing ring is arranged between the outer side of the screw plug and the valve body, and the sealing ring is arranged between the inner side of the screw plug and the valve core; the valve core is arranged in the spring, wherein, one end of which is arranged in a spring seat and the other end of which is arranged in the guide sleeve. The valve core on the rear part of the sleeve is provided with the clamping ring; a pressure plate is arranged between the valve seat and the sleeve, and the outer side of the pressure plate is communicated with the oil inlet. The utility model is characterized in that one end of the valve core is fixedly riveted with a steel ball which pushes the spherical oil outlet in the middle of the valve seat. The product has the advantages of small size, low failure rate, easy fabrication, etc. and does not need a power supply.
Description
Technical field:
The utility model relates to a kind of hydraulic pressure installation, relates more specifically to a kind of small flow hydraulic system that is applicable to, and can manually-operated microswitch valve.
Background technique:
All kinds of miniature electromagnetic valves, the guiding valve of Xiao Shouing mostly is magnet control greatly in the market, and spool and valve base chamber adopt conical surface seal or plane sealing, and this product is influenced by power supply not only, and fault is many, and fluid is filtered the requirement height, and it is very inconvenient to use.
Summary of the invention:
The purpose of this utility model provides a kind of microswitch valve, adopts the steel ball ball face sealing between spool and valve seat, has overcome above-mentioned shortcoming, has reached the purpose that need not power supply, manual operation safe ready.The technical solution of the utility model is: a kind of microswitch valve, comprise: valve body, valve seat, seal ring, collar, sleeve, plug screw, spool, spring seat, spring, guide pin bushing, filler opening, oil outlet, plug screw is pressed on sleeve on the valve seat, the built-in seal ring of the outer side slot of valve seat, put a seal ring between the outside of plug screw and valve body, a seal ring is put with valve core chamber in its inboard, spool places in the spring, one end of spring places in the spring seat, its the other end places in the guide pin bushing, on the spool at sleeve rear portion, establish a collar, put a pressing plate between valve seat and the sleeve, the outside of pressing plate communicates with filler opening, it is characterized in that: an end rivet clasp one steel ball of spool, this steel ball withstand the spherical shape oil outlet in the middle of the valve seat.The utility model and miniature electromagnetic valve compare, and the impacting force of spool and valve base chamber is big, need not power supply, and fault is few; With traditional guiding valve relatively, have volume little, easily manufactured, fluid filtered require all advantages such as low.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Wherein: 1 valve body, 2 valve seats, 3 seal rings, 4 steel balls, 5 pressing plates, 6 collars, 7 sleeves, 8 seal rings, 9 plug screws, 10 seal rings, 11 spools, 12 spring seats, 13 springs, 14 guide pin bushings, 15 filler openings, 16 oil outlets
Embodiment:
As shown in drawings: the utility model comprises: valve body 1, valve seat 2, seal ring 3,8,10, collar 6, sleeve 7, plug screw 9, spool 11, spring seat 12, spring 13, guide pin bushing 14, filler opening 15, oil outlet 16, plug screw 9 is pressed on sleeve 7 on the valve seat 2, the built-in seal ring 3 of the outer side slot of valve seat 2,1 of the outside of plug screw 9 and valve body are put a seal ring 8, its inboard and 11 of spools are put a seal ring 10, spool 11 places in the spring 13, one end of spring 13 places in the spring seat 12, its the other end places in the guide pin bushing 14, on the spool 11 at sleeve 7 rear portions, establish a collar 6, put a pressing plate 5 between valve seat 2 and the sleeve 7, the outside of pressing plate 5 communicates with filler opening 15, one end rivet clasp, one steel ball 4 of spool 11, this steel ball 4 withstand the spherical shape oil outlet 16 in the middle of the valve seat 2.
The other end of the utility model spool 11 is to adopt artificial push-pull fashion to opening into and out of hydraulic fluid port 15,16 with closed.
Working procedure of the present utility model is such: Luo Sai 9 is pressed on sleeve 7, pressing plate 5 on the valve seat 2, the sealing of seal ring 8 and seal ring 10, prevent that fluid from leaking, when spool 11 is closed, spring 13 is by guide pin bushing 14, collar 6, spool 11 is pressed on the valve seat 2, the steel ball 4 of spool 11 heads forms sealing with the spherical shape aperture of valve seat 2, pulling spool 11, make spool 11 lift off a seat 2, fluid enters from filler opening 15, by the passage of pressing plate 5, pass through the aperture of valve seat 2 again, flow out to oil outlet 16.
