Working procedure of the present utility model is:
Figure 1 shows that closed condition of the present utility model.As Fig. 1, fluid 600 flows into oil transport pipeline 2071 from outside fluid input device, enter then in the receiving hole of upper valve body 203, enter by the oil transportation hole 2061 on the stroke adjustment pad 206 in the appearance oilhole 2051 on the hydraulic control piston 205 (shown in Fig. 1 filled arrows) from the back, and fill up and hold oilhole 2051, oil transportation hole 2061 and the receiving hole part above the stroke adjustment pad 206.Under the effect of oil liquid pressure, stroke adjustment pad 206 and hydraulic control piston 205 are together to lower slider, because moving down of hydraulic control piston 205, valve ball 204 is replaced on valve seat 202, the curved surface that is valve ball 204 contacts with the plane of inclination sealing of valve seat 202, thereby the aqueous medium 500 in the aqueous medium input pipeline 101 is stopped by valve ball 204, can't flow to aqueous medium output pipeline 102 by water hole 2032, is trapped in the aqueous medium input pipeline 101 (shown in Fig. 1 hollow arrow).
Figure 2 shows that opening state of the present utility model.As Fig. 2, reduce the fluid 600 that flows into oil transport pipeline 2071 by outside fluid input device, thereby oil liquid pressure reduces, because the pressure of the 500 pairs of valve balls 204 of aqueous medium in the aqueous medium input pipeline 101 exists and is constant at this moment always, so the aqueous medium 500 in the aqueous medium input pipeline 101 is upwards replaced valve ball 204, thereby valve ball 204 is upwards replaced hydraulic control piston 205 and stroke adjustment pad 206, moves to control until stroke adjustment pad 206 and covers 207 inside top surface and can't move.At this moment, valve ball 204 is separated with valve seat 202, aqueous medium 500 in the aqueous medium input pipeline 101 just can flow through by the space of 202 of valve ball 204 and valve seats, flows to aqueous medium output pipeline 102 (shown in Fig. 2 hollow arrow) and flows to outside related device subsequently by water hole 2032 then.
In the transfer process that the utility model is closed and opened, except the seal groove of hydraulic control piston 205 upper design and Sealing are used to stop that fluid 600 flows into the seal groove of aqueous mediums 500 and the design of hydraulic control piston 205 bottoms and Sealing and is used for block water medium 500 and flows into the fluid 600, the mutual string that also can stop fluid and aqueous medium by the sewage draining exit 2033 that upper valve body 203 is provided with. as figure, fluid 600 in the oil transport pipeline 2071 flows downward along the outer wall of hydraulic control piston 205, when Sealing 306,307 can't stop fluid 600 time, fluid 600 can flow out from sewage draining exit 2033, and via drain outlet 208,209, pollutant exhaust hole 210 is discharged in the outside dirt accommodating device, thereby guarantee that fluid 600 can not continue to flow down in the aqueous medium 500 along the outer wall of hydraulic control piston 205. same, aqueous medium 500 in the aqueous medium input pipeline 101 upwards flows along the outer wall of hydraulic control piston 205, when Sealing 303,304 can't block water medium 500 time, aqueous medium 500 can flow out from sewage draining exit 2033, and via drain outlet 208,209, pollutant exhaust hole 210 is discharged in the outside dirt accommodating device, thereby guarantees that aqueous medium 500 can not continue upwards to flow in the fluid 600 along the outer wall of hydraulic control piston 205.
Advantage of the present utility model is: 1, structure of the present utility model is formed simply, but component standardization batch process, and the manufacturing cost is low.2, owing to be the drive fit inclusion seal between upper and lower valve body, contact by the Sealing sealing and fixing between upper and lower valve body and integrated package, and upper valve body and hydraulic control piston space seal sliding contact by Sealing, thereby, fluid and aqueous medium be difficult for to take place and go here and there phenomenon mutually in good airproof performance of the present utility model.And because design has a pollution discharge structure, thereby in the process of fluid control aqueous medium one-way flow, the utility model can prevent more effectively that fluid and aqueous medium from going here and there the generation of phenomenon mutually, and sealing is strong, the reliability height.3, because valve seat in the utility model and the design of the contacted sealing of valve ball position have the plane of inclination of several angle, compare the valve seat and the spool design of known Pilot operated check valve, such design makes the force-bearing situation of valve seat and valve ball be improved, not easy to wear, long service life, and the making required precision of valve seat in the utility model and valve ball is low, but standardized production.4, the utility model can effectively be realized the one-way flow of fluid control aqueous medium.And, can be on the integrated package in the utility model according to the actual a plurality of fluid-control one-way valve assemblys of plug-in mounting that require, a plurality of Pilot operated check valve inter-modules can be realized multiple commutation function by the various combination Connecting format, as two four-ways, 3-position 4-way, two-bit triplet commutation function.
The above is preferred embodiment of the present utility model and the know-why used thereof; for a person skilled in the art; under the situation that does not deviate from spirit and scope of the present utility model; any based on conspicuous changes such as the equivalent transformation on the technical solutions of the utility model basis, simple replacements, all belong within the utility model protection domain.
