Embodiment
The utility model provides a kind of cylinder type ROLLING OIL injection valve, brings into play its function with the stack mounting of beam body.Comprise filler opening, an inner chamber that links to each other with filler opening on its beam body, inner chamber is the trapped fuel space, and the ROLLING OIL that desire is sprayed lodges in this space with high voltage style; The valve seat of injection valve provides a ROLLING OIL passage from inner chamber to external nozzle, and the ROLLING OIL of pressurization imports the oily passage that is limited by filler opening; A valve head that is arranged on Liang Tizhong, valve head moves between an operating position and an enable possition, opens and closes the ROLLING OIL passage; A valve head is removed device, is used for valve head is removed from the valve seat hydraulic fluid port, thereby allows ROLLING OIL to enter the ROLLING OIL passage, and oil is from exporting by nozzle ejection to appointed part; A valve head driving mechanism drives valve head and valve seat hydraulic fluid port closure, thereby stops ROLLING OIL to enter the ROLLING OIL passage.
As shown in Figure 1, cylinder type ROLLING OIL injection valve, depending on the beam body installs, whole injection valve is by valve seat 1, valve head 4, straight pin 5, piston type valve rod 6, piston 7, cylinder block 11, flange 10, spring 9, compositions such as cylinder head 8 and some seal rings, valve seat 1 is installed on the sidewall of beam body 12, the valve head driving mechanism adopts cylinder-type drive set, cylinder-type drive set is arranged on the opposite side of beam body 12, its cylinder block 11 fixes by flange 10 and beam body 12, its piston type valve rod 6 passes the beam body sidewall and stretches in the beam body 12, and the centerline of the center line of piston type valve rod 6 and valve seat 1 is in same axis; Valve head 4 is installed in the front end of piston type valve rod 6 by bearing pin 5 with ralocatable mode, valve head 4 and valve seat 1 over against, be provided with groove with the contacted end face of valve seat on the valve head 4, sulfuration has nitrile butadiene rubber 3 in the groove; Be provided with flange stepped part 2 with the contacted end of valve head on the valve seat 1; The mobile driving valve head 4 and valve seat 1 hydraulic fluid port of piston type valve rod 6 carry out closure.It is elastic member 9 that valve head is removed device, be arranged on the rearward end of piston type valve rod 6, its spring overcoat is on piston type valve rod 6, and an end of spring is connected with cylinder block 11, the other end is connected with piston 7, leans on the elastic force of spring that valve head 4 is removed from the hydraulic fluid port position of valve seat.On the oil outlet of valve seat 1 nozzle is housed.
In the valve head 4 of brass mounted sulfurized nitrile rubber 3 is arranged, and be connected with valve rod 6 gaps in the pin mode, valve head 4 is in quick condition, plays good correcting effect, guarantees the closed that valve head 4 and valve seat 1 are superior.The geomery of valve head 4 and valve seat 1 makes valve head not be subjected to the effect of fluid pressure in the beam body as far as possible when valve cuts out, be provided with flange stepped part 2 with valve head 4 contacted ends on the valve seat 1, so that valve does not need very big spring force and the not influence of liquid body pressure size as far as possible when opening.Cylinder block 11 is separated design with fastening flange 10, saves material, has reduced the cutting amount.
During concrete the application, ROLLING OIL is flow to by import, shown in A, has been full of the ROLLING OIL that pressure is arranged in the chamber of beam body, is flowed out by outlet, and shown in B, thereby ROLLING OIL sprays to roll and rolled piece equably from the nozzle on the valve seat oil outlet.When needing to stop to spray in the rolling mill practice process, feed pressurized air from the suction port of cylinder head 8, shown in C, pressurized air enters in the piston cavity of cylinder block, promotion piston 7 overcomes spring force, surface friction drag and liquid force and advances, piston type valve rod 6 drives valve head 4 and is pressed on the valve seat 1, and the ROLLING OIL pathway closure stops to spray; When needs begin to spray, remove pressurized air, piston 7 overcome friction and retreating under the effect of spring force, piston type valve rod 6 drives valve heads 4 and breaks away from valve seat 1, and the ROLLING OIL passage is opened, and sprays.
In sum, the utility model is realized switch by piston motion, and valve head is in quick condition, automatic guiding when the assurance valve head contacts with valve seat, and switch and sealing reliability are good.Relatively low to the bleed pressure requirement, even oil supply pressure is higher, source of the gas also need not special processing.Working life is longer, and economic benefit and social effect are remarkable.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
