Technical Field

The utility model relates to the technical field of ball valves, in particular to a clamp type connecting ball valve.

Background

And the opening and closing piece (ball body) is driven by the valve rod and rotates around the axis of the ball valve. Ball valves are used in pipelines mainly to cut off, distribute and change the flow direction of a medium, and can be tightly closed only by rotating the ball valve by 90 degrees and small rotating moment. However, when the ball valve is used daily, the hand wheel of the ball valve is in a free state, and serious consequences are easily caused by misoperation.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a clamp formula connection ball valve, includes first valve body and the second valve body of relative setting, be equipped with the spheroid between first valve body and the second valve body, one side that first valve body and second valve body are close to each other is equipped with flange along the circumference, two the last two clamps that match of flange have relative setting, two pass through bolted connection between the clamp, be equipped with the medium circulation passageway on the spheroid, be equipped with the valve rod that passes flange and clamp on the spheroid, valve rod and flange cooperation department are equipped with the sealing washer, the valve rod wears out flange's part along the axial and is equipped with the spacing groove, the cover is equipped with the sliding sleeve on the valve rod, the sliding sleeve internal face is equipped with spacing arch with spacing groove complex, the sliding sleeve cross section is polygonal structure, be equipped with on the sliding sleeve up end and/or the lateral wall with medium circulation passageway direction correspondence's mark, be equipped with on the clamp with sliding sleeve complex polygonal spacing hole.

The ball body is arranged between the first valve body and the second valve body, and the first valve body and the second valve body are fixed through two clamping bands, so that the ball valve can be quickly installed; the sliding sleeve and the valve rod are matched through the limiting groove and the limiting protrusion, so that the sliding sleeve can only axially slide along the valve rod, and the sliding sleeve cannot rotate along the valve rod; the marks on the upper end surface and/or the side wall of the sliding sleeve obviously indicate the position orientation of the medium circulation channel, and the opening and closing of the ball valve are realized by rotating the valve rod. When the sliding sleeve is matched with the limiting hole on the clamp, the valve rod cannot rotate along the axial direction, so that the position angle of the medium circulation channel in the ball body is limited. The sliding sleeve is matched with the limiting holes at different angles, so that the medium circulation channel is fully opened, fully closed or opened in proportion, and the shapes of the sliding sleeve and the limiting holes can be adjusted according to actual needs.

Further, the valve rod top can be dismantled and be connected with the carousel that prevents sliding sleeve roll-off valve rod, the length of sliding sleeve is less than the clamp top and to the distance between the carousel. The top of the valve rod is provided with the rotary table, so that the ball body can be conveniently rotated on one hand, and on the other hand, the sliding sleeve can be prevented from being separated from the valve rod and lost when being pulled out of the limiting hole. The length of the sliding sleeve is smaller than the distance between the top end of the clamp and the rotary table, so that the sliding sleeve can be conveniently pulled out of the limiting hole.

Further, the upper end of the sliding sleeve is made of a magnet block, and the diameter of the magnet block is larger than the longest diagonal of the sliding sleeve. The diameter of the magnet block is larger than the longest diagonal of the sliding sleeve, so that the sliding sleeve can be conveniently pulled out of the limiting hole; after the sliding sleeve is pulled out of the limiting hole, the rotary table is sucked through the magnet block, so that the sliding sleeve does not need to be supported when the rotary table is rotated, and the sliding sleeve is prevented from falling into the limiting hole again, and the rotation of the valve rod is influenced.

Further, the cross section of the sliding sleeve is square, regular octagon or regular dodecamorphism. When the section of the sliding sleeve is square, the rotation is at least 90 degrees at one time, so that the quick switching between the full opening and the full closing of the ball valve is realized; when the cross section of the sliding sleeve is regular octagon, the rotation is at least 45 degrees once, and when the cross section of the sliding sleeve is regular dodecagon, the rotation is at least 30 degrees once, so that the full opening, the full closing or the proportional opening of the ball valve is realized.

The beneficial effects of the utility model are as follows: according to the clamp type connecting ball valve, the sliding sleeve is matched with the limiting hole, so that the ball valve is fully opened, fully closed or opened in proportion, the turntable cannot rotate after being touched by mistake, and serious consequences are avoided.
