Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples
Present embodiment is one and is applied in the petrochemical system transfer line, model is the upper-mounting type ball valve of Q347F-300C, comprise valve body 1, spheroid 2, Lower shaft sleeve 3, lower bearing 4, spring 5, valve seat graphite circle 6, valve seat O shape circle 7, valve seat support ring 8, seal ring 9, bonnet gasket 10, valve gap 11, Upper shaft sleeve 12, valve rod 13, valve rod O shape circle 14, valve rod graphite circle 15, gland 16, valve stem sleeve 17, upper bearing (metal) 18 and valve gap O shape circle 19 structures by accompanying drawing 1 install, wherein: 1) dress formula structure in the employing, be that latus rectum is φ 250mm, two end flange of the valve body 1 of cast steel part can be fixedly mounted in the pipeline, Cast Steel, lid mouthful method lid diameter is that the valve gap 11 of φ 590mm is installed in valve body 1 top by 16 M24 bolts, by opening valve gap 11, can install, dismounting all upper-mounting type ball valves except that valve body 1 are part in addition; 2) hollow ball structure, at radius R be 200mm spheroid 2 laterally be processed with full passing hole with 1 liang of same diameter phi 252mm of end flange through hole of valve body, the central axis place of the top and bottom of spheroid 2 is cylinder spindle noses of two diameter phi 90mm, all the other all are lathed up and down two planes, and making spheroid 2 is to have strengthened the hollow spheres that latus rectum has alleviated weight again; 3) valve rod, spheroid are reliably located, the valve rod 13 of diameter phi 65mm passes through valve stem sleeve 17 in valve gap 11 center axially locating, the square spindle nose in valve rod 13 lower ends cooperates with the interior square opening of the cylinder spindle nose of spheroid 2 upper ends, the substantially horizontal of spheroid 2 is by valve body 1 bottom Lower shaft sleeve 3 and valve gap 11 bottom Upper shaft sleeves 12 location, lower bearing 4 and upper bearing (metal) 18 location that Vertical direction is made by the little self lubricating material of surface friction drag; 4) sealing configuration, valve gap 11 and valve gap O type circle of making being connected of valve body 1 19 and bonnet gasket 10 sealings by rubber; Valve rod 13 seals with the valve rod O type circle 14 and the valve rod graphite circle 15 that are connected by rubber of gland 16; The valve seat support ring 8 of the right and left seals with the valve seat O type circle 7 and the valve seat graphite circle 6 that are connected by rubber of valve body 1; Spheroid 2 seals with the seal ring 9 that the flexible connection of the valve seat support ring 8 of the right and left that is installed in valve body 1 is made by the enhancing PTFE, because of the spring 5 that is become by the steel traveler of diameter phi 2.5mm on the valve seat support ring 8 is supported on elastic force effect on the valve body 1, make seal ring 9 more tight with the sealing of spheroid 2, reliably.Suffered medium power is delivered on valve body 1 and the valve gap 11 by Lower shaft sleeve 3 and Upper shaft sleeve 12 in the ball valve body that this enforcement is fallen, valve rod 13 no longer is subjected to the power effect of duct orientation, make valve rod 13 transmitting torque when driving spheroid 2 rotations, stress is changed, and the whole driving torque of valve is reduced.
During low pressure, valve component slides forward under the effect of spring force and compresses spheroid, and spheroid is fixed by last Lower shaft sleeve, produces seal pressure like this between seal ring and spheroid, thereby realizes low pressure seal.During high pressure, valve component slides forward under the effect of medium power and compresses spheroid, thereby realizes high pressure sealing.The O shape circle that is sealed into of valve seat and valve body makes up with the graphite circle, guarantees reliable sealing.Axially by spheroid metal (upper location, bearing is a self lubricating material to spheroid, and surface friction drag is little.Stem lower portion is provided with axle sleeve, and the surface friction drag when reducing the valve rod rotation, valve stem seal adopt O shape circle and the combination of graphite circle, and the assurance sealing is reliable.The top connects dish and can make things convenient for drive unit and be connected.
When valve rod turns clockwise, drive spheroid rotation, valve closing by valve rod; Otherwise, when being rotated counterclockwise, valve opening.
