Abstract
Disclosed is a ball cock which comprises a valve body, a lever which drives a valve core of the valve body to move and a floating ball which drives the lever to move. The utility model is characterized in that the lever is a three-stage lever which primarily comprises a first lever which directly drives the valve core to move, a second lever, a third lever, a first connecting rod and a second connecting rod. Compared with prior art, the utility model has the advantages that the ball cock has enough impetus to drive the valve core so as to meet the operation needs of the big flux ball cock.
Description
Technical field:
The utility model relates to a kind of valve, particularly a kind of float valve.
Background technique:
Existing float valve is mainly by valve body, drive the lever of valve body spool action, the ball float that drives lever motion constitutes, in order to improve the power of ball float by the action of lever drives spool, someone has designed the double lever float valve again, promptly add a lever again, one of lever is actively socketed on the valve body, other end and ball float are fixed together, fulcrum is then hinged with a wherein end of a connecting rod, the other end of connecting rod and original lever termination are hinged, though this kind float valve has been strengthened the power of ball float promotion spool to a certain extent, but when being used on the large flow ball float valve, its Driving force that promotes spool also seems not enough.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of has enough Driving forces to promote spool, to satisfy the float valve of large flow ball float valve operation needs.
The utility model is to realize like this, comprise valve body, drive the lever of valve body spool action, drive the ball float of lever motion, its specialization is that lever is three grades of levers, the primary lever that these three grades of levers are mainly moved by direct drive spool, second lever, three grades of levers, elementary connecting rod, the secondary connecting rod constitutes, a wherein end of the movable end of primary lever and elementary connecting rod is hinged, a wherein end of second lever is hinged on the valve body, the other end of its fulcrum and elementary connecting rod is hinged, a wherein end of three grades of levers is hinged on the valve body, movable end and ball float link together, a wherein end of its fulcrum and secondary connecting rod is hinged, and the other end of secondary connecting rod and the movable end of second lever are hinged.
During work,, make the Driving force that acts on the spool be multiple ground and improve, guaranteed that big flow, high hydraulic pressure float valve effectively close in time under the drive of ball float by the amplification of three grades of levers.
Here, the second lever movable end is the arcuation of up perk to the body of rod of fulcrum.Because the direction of second lever movable end indication is consistent with the direction of secondary connecting rod, like this, when the secondary connecting rod up moves three grades of lever drives, the angle of secondary connecting rod and second lever is constant substantially, that is to say that secondary connecting rod and second lever need not rotate along both articulating points just can pass to primary lever with Driving force, like this with regard to avoided because of on the articulating point between connecting rod, lever in use frictional force strengthen the transmission that has influenced thrust gradually.
The utility model compared with the prior art, having has enough Driving forces to promote spool, to satisfy the advantage of large flow ball float valve operation needs.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises valve body 1, drive the lever 2 of valve body 1 spool action, drive the ball float 3 of lever 2 motions, its specialization is that lever 2 is three grades of levers, the primary lever 4 that these three grades of levers are mainly moved by direct drive spool, second lever 5, three grades of levers 6, elementary connecting rod 7, secondary connecting rod 8 constitutes, the movable end 10 of primary lever 4 is hinged with a wherein end of elementary connecting rod 7, a wherein end of second lever 5 is hinged on the valve body 1, its fulcrum 9 is hinged with the other end of elementary connecting rod 7, a wherein end of three grades of levers 6 is hinged on the valve body 1, movable end 11 links together with ball float 3, its fulcrum 12 is hinged with a wherein end of secondary connecting rod 8, the movable end 13 of the other end of secondary connecting rod 8 and second lever 5 is hinged, and second lever 5 movable ends 13 are the arcuation of up perk to the body of rod of fulcrum 9.
Claims (2)
1, a kind of float valve, comprise valve body, drive the lever of valve body spool action, drive the ball float of lever motion, it is characterized in that lever is three grades of levers, the primary lever that these three grades of levers are mainly moved by direct drive spool, second lever, three grades of levers, elementary connecting rod, the secondary connecting rod constitutes, a wherein end of the movable end of primary lever and elementary connecting rod is hinged, a wherein end of second lever is hinged on the valve body, the other end of its fulcrum and elementary connecting rod is hinged, a wherein end of three grades of levers is hinged on the valve body, movable end and ball float link together, a wherein end of its fulcrum and secondary connecting rod is hinged, and the other end of secondary connecting rod and the movable end of second lever are hinged.
