Embodiment
Below in conjunction with Fig. 1,2, the utility model is described further.
Such as Fig. 1, shown in 2, preference of the present utility model is a kind of diaphragm fast-opening type mud discharge valve, it comprises valve body 1, valve rod 2, valve plate, described valve plate is divided into large valve plate 3 and little valve plate 4, large valve plate 3 and little valve plate 4 are provided with through hole 12,13, described valve rod 2 passes little valve plate through hole 13 and is fixedly connected with little valve plate 4, little valve plate 4 surfaces are provided with encapsulate layer 6, the gap that little valve plate through hole 13 inwalls and valve rod are 2 is provided with O-ring seals 7, described valve rod 2 lower ends are fixedly connected with sliding sleeve 5, described sliding sleeve 5 is arranged in the large valve plate through hole 12, sliding sleeve 5 is flexibly connected with large valve plate 4, one end of sliding sleeve 5 stretches out the lower end that large valve plate through hole 12 is positioned at large valve plate 3, described large valve plate 4 lower ends are fixedly connected with large valve plate pressing plate 8, large both sides, valve plate 3 lower end have the groove 9 of embedded caulking gum 10, and described large valve plate 3 has stainless steel lining 11 with the sealing surface weld deposit that little valve plate 4 contacts.
The utility model diaphragm fast-opening type mud discharge valve is when opening, use hydraulic press or air compressor gas pressurized, import and export 15 through water or air after 14 commutations of two-position four-way solenoid directional control valve by the diaphragm cavity of resorption and enter diaphragm seat cavity of resorption, promote diaphragm and diaphragm pressing plate and move upward together, be with simultaneously ovable valve stem 2 and little valve plate 4 to move upward together.Stretch out the lower end that large valve plate through hole 12 is positioned at large valve plate 3 owing to being fixedly connected with the lower end of sliding sleeve 5 and sliding sleeve 5 in valve rod 2 lower ends, when driving little valve plate 4 rising, when valve rod 2 drive sliding sleeves 5 make little valve plate 4 risings a bit of, large valve plate 3 is not driven by sliding sleeve 5 and rises, this moment, little valve plate 4 and large 3 of valve plates were at regular intervals, this intersegmental distance equals the spacing of the lower end of sliding sleeve 5 lower ends and large valve plate 3, large valve plate 3 is motionless under the effect of hydraulic pressure, after waiting for that hydraulic pressure sheds a part, control hydraulic press or air compressor pressurization continue band ovable valve stem 2 and rise, the at this moment lower end of sliding sleeve 5 and greatly 3 times end in contact of valve plate, valve rod 2 drives sliding sleeve 5 and then drives large valve plate 3, large valve plate pressing plate 8 moves upward together until all open, and has so just finished little valve plate 4 and the large opening process of valve plate 3.The purpose of this technological scheme is exactly that very large water pressure is shed a part, opens under less pressure again.This technological scheme result is exactly that hydraulic pressure or air pressure driving force are little, and energy consumption is few in the opening process.
