Embodiment
A kind of high life high-pressure stop valve of the present utility model, as depicted in figs. 1 and 2, including handwheel, stuffing seal, valve gap, valve rod, valve body 1, flap 2, wherein valve body 1 is provided with access road 3, inner passage 4, flap passage 5, exit passageway 6；Installation portion 9 that flap 2 includes being connected with valve rod, the cut-off portion 10 in cone, hemispherical flap sealing 11.Inner passage 4 and flap passage 5 are on the same axis and junction is provided with valve body sealing surface 7, the axial line that inner passage 4, flap passage 5 flow to fluid is 45 ° of Y types, flap passage 5 connects near that one end of valve body sealing surface 7 and exit passageway 6, exit passageway 6 includes between the first exit passageway 13 and the second exit passageway 14 and two passages shape in obtuse angle, and the second exit passageway 14 and access road 3 are in the same direction.Valve body sealing surface 7 is provided with valve seat 8 with the corner of inner passage 4, valve clack sealing surface 12 and the valve seat 8 on valve body sealing surface 7 are linear sealing, the flap sealing 11 of flap 2 and the junction in cut-off portion 10 are provided with valve clack sealing ring 15, and valve clack sealing ring 15 and valve seat 8 are linear sealing.It addition, valve body 1 is 304 materials, valve clack sealing surface 12 is 304 to be cladded with built-up welding STL.
When flap 2 is opened, during medium circulation, fluid travel distance and flow to for bottom horizontal flow sheet, 135 ° turn round, obtuse angle turns round, somewhat changed course be adjusted to bottom horizontal flow sheet, its process is mild, fluid resistance is less, wherein after the break-in relatively relaxed for twice, water outlet direction is consistent with water inlet direction, and the pressure loss that fluid passes through stop valve is less.The flap sealing 11 of flap 2 is hemispherical, and its size shape is suitable to the size shape of inner passage 4, and spherical toleration is strong, in any point by active force, power can spread out uniformly to surrounding, thus spherical firmer than any shape, can preferably bear fluid scouring power；Further, valve clack sealing surface 12 is 304 to be cladded with built-up welding STL, i.e. Stevr alloy, exceptional hardness, and resistance to erosion is corrosion-resistant；It addition, fluid travel distance is mild, resistance is little, therefore also reduces the scouring force of valve clack sealing surface 12；And the design reduces the possibility that impurity is detained, it is to avoid impurity, the solid particle abrasion to sealing surface；Above-mentioned combination, more promotes being greatly improved of stop valve life-span.
When flap 2 Guan Bi is dammed, valve rod promotes flap 2 to overcome fluid pressure to move along flap passage 5 internally passage 4, until flap sealing 11 enters inner passage 4, and valve clack sealing surface 12 contacts with the valve seat 8 on valve body sealing surface 7, compresses in linear sealing state.Integral valve body 1, valve rod are integrally machined with flap 2, make valve have higher concentricity, and valve rod uses high strength steel hardness high, makes hardfacing alloy valve clack sealing surface 12 have enough mother metal hardness to support, prevents Ovum crusta Gallus domesticus phenomenon.It addition, when abrasion occurs in valve clack sealing surface 12, during poor sealing, can continue to advance valve rod and flap 2, make valve clack sealing ring 15 contact with the valve seat 8 on valve body 1, compress in linear sealing, sealing reliability is greatly improved.
The above is only preferred implementation of the present utility model; it is noted that for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement, these improvement also should be regarded as protection domain of the present utility model.
