Abstract
The utility model relates to a track guide type ball valve, comprising a machine frame, a ball core and a valve body. The utility model is characterized in that the ball core is composed of a left and a right sealing sheets 11, a wedge shaft block 8, a valve rod 14 and a pressure pin 12. The wedge shaft block and the valve rod are connected into integration. The valve rod is tightly connected with a screw rod 6 on the machine frame by a positioning lateral pin 7. The wedge shaft block is assembled and connected with the left and the right sealing sheets by a wedge T-shaped groove. The combinatorial ball core is formed by that the small sphere-shaped centre hole of the bottom part of the left and the right sealing sheets is loaded in the pressure pin 12. A track guide groove is arranged on a machine frame body. The positioning pin 7 is positioned on the track guide groove 15. The utility model has the advantages of unlimited flow direction, bidirectional sealing, no abrasion sealing surface, small flow resistance, quick opening and closing, portable operation, labor saving, convenient maintenance, etc.
Description
The utility model relates to a kind of ball valve.
Ball valve generally comprises frame, ball core and valve body three parts and forms, the ball core and the valve rod of traditional type ball valve easily comes off, heavy caliber keying moment is big, wrench is long, need bigger installing space, to dismantle valve body during maintenance, medium during work in the valve pocket can't be discharged accumulations, and especially sealing surface is easy to wear.
The utility model purpose is to provide a kind of sealing surface not have wearing and tearing, opens and closes piece, easy to operate, laborsaving, volume is little, flow resistance is little novel ball valve.
The technical solution of the utility model is to adopt combination ball core and rail conduction frame, its detailed technology content in conjunction with the embodiments and accompanying drawing be described.
Fig. 1 is a kind of embodiment's of the utility model rail conduction ball valve a structural representation.
Fig. 2 be Figure 1A to sectional view.
Fig. 3 be Figure 1B to sectional view.
By figure, this rail conduction ball valve comprises frame, ball core and valve body, frame comprises handwheel 1, square cotter 2, nut 5, bearing cap 3, screw rod 6 and frame main body 4, valve body comprises valve body main body 10 and valve gap 9, it is characterized in that the ball core by about the sealing slit bamboo or chopped wood 11, wedge-type axle piece 8, valve rod 14 and press-on pins 12 are formed, wedge-type axle piece and valve rod are connected as a single entity, valve rod and screw rod 6 usefulness location lateral pin 7 are fastenedly connected, wedge-type axle piece with about the sealing slit bamboo or chopped wood be connected with wedge-type T type groove, about the sealing slit bamboo or chopped wood bottom microspheric form center hole press-on pins 12 of packing into form and make up ball cores, rail guide groove 15 on the frame main body 4, location lateral pin 7 is positioned on the rail guide groove 15, rail guide groove certain angle α that is inclined upwardly.In combination ball core is packed valve body main body 10 into, be connected with main body 10 by valve gap 9, the valve rod 14 that makes combination ball core is by valve gap 9 location, and the bottom microspheric form is by main body 10 location, determine combination ball core center height by the limit plug on the valve body 13 at last, make combination ball core be fixed on central position in the valve pocket.
When handwheel right-hand rotation drive screw 6 rises, location lateral pin 7 rises to the top simultaneously, nut 5 is just produced the effect that tightens up with screw rod 6, when tightening up, screw rod 6 produces right-handed moment immediately following nut 5 with handwheel direction continuity, rail guide groove inclination angle a is a top rade simultaneously, slides to 90 ° on guiding location lateral pin 7 is turned right and ends.Drive wedge axle piece simultaneously and rise when screw rod 6 rises, sealing slit bamboo or chopped wood 11 draws close to the center about making, and has broken away from the sealing surface of main body 10, simultaneously also and then the handwheel direction rise to turn right to 90 ° and end.It is standard-sized sheet that ball core port and valve body port connection MEDIA FLOW is crossed.Otherwise when closing, by 90 ° in handwheel continuity transmission elder generation rotating sphere core, then under the wedge axle piece general who has surrendered's ball core about the sealing slit bamboo or chopped wood separately, the sealing slit bamboo or chopped wood was relied on oneself and compresses about press-on pins 12 was fixed, can not slide, limit plug 13 fixedly ball core center height be not shifted and about the effect that do not misplace of sealing slit bamboo or chopped wood, make with valve body sealing surface and do not produce friction, fitting at leisure compresses, and promptly blocking media flow is complete shut-down.
The flow direction that has this ball valve does not limit, two way seal, sealing surface do not have wearing and tearing, flow resistance is little, open and close piece, operation is light Laborsaving, easy to maintenance, can automatically clean in sealing area and the valve pocket advantages such as accumulations.
