Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 1～shown in Figure 6, the valve rod 5 that the ball valve of present embodiment includes valve body 1, is arranged on spherical valve core 3, the handle 4 in the valve body 1 and connects handle 4 and spherical valve core 3 rotationally;
Wherein, valve body 1 is both ends open vertically, a wherein end of axially open be connected with a joint 1 ', valve body 1 has the protruding neck 2 in a tape spool hole 11 at vertical side; For guaranteeing sealing effect, spherical valve core 3 is respectively arranged with first sealing gasket 321 and second sealing gasket 322 in the contacting point of its surface, gateway, rear and front end and valve body 1 passage; Valve rod 5 is plugged in the axis hole 11; And be arranged with O RunddichtringO 55 on the valve rod 5, the two ends of valve rod 5 are two flat sides respectively, and handle 4 offers the mounting hole 41 that a flat side in upper end who supplies valve rod 5 passes; The flat side in upper end passes mounting hole 41 backs and connects a nut 6 and handle 4 secure fit; The flat side in the lower end of valve rod 5 closely cooperates after groove 31 on the ball-type spool 3 is pegged graft with being opened in, and handle with sleeve 4 promptly drives valve rod 5 and rotates together, and the opening and closing of realization spherical valve core 3.
In order to realize anti-theft feature; And improve the operational reliability of antitheft; Valve body 1 also has two and establishes and radially overhanging first boss 21 and second boss 22 relatively on protruding neck 2; First boss 21, second boss 22 offer first through hole 211 and second through hole 221 respectively along the axial direction perpendicular to protruding neck 2; In order to prevent artificial destruction, sealing is fixed with first lead sealing 71 and second lead sealing 72 respectively in the outer end of first through hole 211 and second through hole 221, and; Be provided with the first magnetic pin 91 in first through hole 211 and make the first magnetic pin, 91 outer ends in the axis hole of protruding neck 2, be provided with the second magnetic pin 92 in overhanging first spring, 81, the second through holes 221 and make the second magnetic pin, 92 outer ends overhanging second spring 82 in the axis hole of protruding neck 2;
The outer side wall of valve rod 5 offers first blind hole 51 and second blind hole 52 respectively in the both sides of establishing relatively; And; The axis line of first blind hole 51 and second blind hole 52 is perpendicular with the axis of spherical valve core 3 all the time; In order to realize the locking of spool in advance, the end face of first blind hole 51 also is formed with to offer along clockwise direction and be to offer equally on the end face of semi-moon shaped first restraining groove, 511, the second blind holes 52 to be offered along clockwise direction and is semi-moon shaped second restraining groove 521; First restraining groove 511 and second restraining groove 521 also can be along counterclockwise offering, if keep first restraining groove 511 and second restraining groove 521 to offer direction consistent.
As shown in Figure 4; Be the schematic representation under spherical valve core 3 full open position, at this moment, the first magnetic pin 91 in first blind hole 51 on the valve rod 5 and first through hole 211 shifts to install; The outer of the first magnetic pin 91 corrects on the outer side wall that is resisted against valve rod 5; In like manner, the second magnetic pin 92 in second blind hole 52 on the valve rod 5 and second through hole 221 also shifts to install, and the outer end of the second magnetic pin 92 is resisted against on the outer side wall of valve rod 5;
After valve rod 5 turns over several angle along spherical valve core 3 closing directions (valve rod 5 is rotated in a clockwise direction); As shown in Figure 5, at this moment, first restraining groove 511 of valve rod 5 is facing to first through hole 211; The first magnetic pin 91 is protruding and be limited in this first restraining groove 511 under the resilient force of first spring 81; 521 of second restraining grooves of valve rod 5 are overhanging and be limited in second restraining groove 521 under the resilient force of second spring 82 facing to second through hole, 221, the second magnetic pins 92, but at this moment spherical valve core 3 is not in buttoned-up status; Because the stopping effect of first restraining groove 511 and second restraining groove 521; Make that valve rod 5 can't be again along revolution counterclockwise, promptly when ball valve goes in the several angle as shown in Figure 5, at this moment before closing fully; Ball valve promptly begins to realize the self-locking stopping function, effectively prevent ball valve in closing closed procedure because of arbitrarily back and forth rotation valve rod 5 cause dangerous consequence;
When valve rod 5 continues to turn to position as shown in Figure 6 along clockwise direction; At this moment; First blind hole 51 faces first through hole, 211, the first magnetic pins 91 and inserts and be limited in first blind hole 51, and second blind hole 52 faces second through hole 221; The second magnetic pin 92 inserts and is limited in second blind hole 52, and spherical valve core 3 is in buttoned-up status.When ball valve is in lockup state as shown in Figure 5 or as shown in Figure 6 when closing lock state, open handle 4 once more, all must use special strong magnetic to open key and can open ball valve once more.
The ordinary ball valve that realized present embodiment can't realize the function of ball valve locking in the several angle that spool is closed fully, can reduce the misoperation in the ball valve locking process, further improves the antitheft reliability of ball valve.
