two short sliding shafts 6; two short sliding shafts 6 are fixedly arranged on the outer wall of the inner track 4;
the side wall of the outer rail 5 is provided with two ring grooves 51, the end of each ring groove 51 is provided with an inclined downward groove 511, sliding shafts are placed in the ring grooves 51, the inner rail 4 is rotatably connected with the outer rail 5, and the outer rail 5 is fixedly connected with the lower end of the valve cover 10;
the end of the elastic element 7 is contacted with the lower bearing 101, the other end of the elastic element 7 is contacted with the inner track 4, and the elastic element 7 is in a compressed state;
the track control structure comprises a long sliding shaft 3; the two ends of the long sliding shaft 3 are both provided with sliding bosses 31, the long sliding shaft 3 is arranged in the long sliding shaft limiting groove 11, and the sliding bosses 31 protrude out of the long sliding shaft limiting groove 11;
two arc-shaped limiting bosses 41 are formed at the upper end of the inner rail 4, transmission grooves 42 are vertically formed in the inner sides of the ends of the limiting bosses 41, two sliding grooves 44 are formed between the two limiting bosses 41, the two transmission grooves 42 and the two sliding grooves 44 are respectively symmetrical according to the axial central line of the inner rail 4, and the two sliding bosses 31 respectively slide in the two sliding grooves 44.
The angles of both annular grooves 51 are 90 °.
The elastic member 7 in this application is preferably a spring.
Also shown in this application is a universal joint 8; the lower end of the valve core 2 is connected with the bottom of the air flow passage in the valve body base through a universal joint 8.
The working time of the embodiment is divided into several states:
when the valve is opened, the valve driving device drives the valve rod 1 to rotate forward, the eccentric shaft 12 on the valve rod 1 drives the valve core 2 to swing (this is the prior art, please refer to fig. 7), the long sliding shaft 3 rotates with the valve rod 1 , when the sliding boss 31 of the long sliding shaft 3 contacts with the side 421 (as shown in fig. 10) of the transmission groove 42 on the inner rail 4, the valve rod 1 drives the inner rail 4 to rotate forward through the long sliding shaft 3, the stopper 43 on the inner rail 4 drives the valve core 2 to rotate forward with the inner rail 4, the short sliding shaft 6 moves to the higher end of the ring groove 51 in the ring groove 51 on the outer rail 5, at this time, the inner rail 4 rises to slide the long sliding shaft 3 into the transmission groove 42 on the inner rail 4, the elastic element 7 is compressed, when the short sliding shaft 6 moves to the higher end of the ring groove 51 (this can be understood as sliding out from the groove 511 of the ring groove 51 (as shown in fig. 11);
when the valve is closed, the driving device drives the valve rod 1 to rotate reversely, the long sliding shaft 3 is driven by the valve rod 1 to contact with the second side 422 of the transmission groove 42 as shown in fig. 10), the valve rod 1 drives the inner rail 4 to rotate reversely through the long sliding shaft 3, the limiting block 43 on the inner rail 4 drives the valve core 2 to rotate reversely along with the inner rail 4 , the short sliding shaft 6 moves to the lower end of the ring groove 51 in the ring groove 51 on the outer rail 5 (initially, the short sliding shaft 6 slides in the plane in the ring groove 51), when the short sliding shaft 6 moves to the lower end of the ring groove 51 (the short sliding shaft 6 slides in the groove 511 of the ring groove 51), the inner rail 4 does not rotate any more, because the elastic part 7 is compressed, the inner rail 4 can descend to the original position under the action of the elastic part 7 to enable the long sliding shaft 3 to slide out of the transmission groove 42, the long sliding shaft 3 continues to rotate reversely under the drive of the valve rod 1, enters the sliding groove, and stops rotating until the valve is closed;
after the valve is closed in place, the valve core 2 is in contact collision with the sealing ring 9 (as shown in fig. 1), the valve core 2 tends to bounce to drive the inner rail 4 to rotate towards the valve opening direction, and because the limiting boss 41 on the inner rail 4 is in contact with the long sliding shaft 3, the inner rail 4 inevitably drives the valve rod 1 to rotate through the long sliding shaft 3 when rotating towards the valve opening direction, the valve rod 1 drives the whole driving device to move, and actually, the bounce generated by the contact collision of the valve core 2 and the sealing ring is far less than the force required for driving the whole driving device to move, so that the whole driving device cannot be driven by the valve rod 1, the inner rail 4 and the valve core 2 cannot rotate due to the bounce, and the problem that the valve is not closed tightly due to the bounce of the valve core.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
