Abstract
The utility model discloses a ball valve convenient to control. The ball valve convenient to control comprises a valve body and a valve deck. The valve body is connected with the valve deck through a flange. A ball-valve valve clack is arranged inside the valve body. A valve rod connected with the ball-valve valve clack is arranged on the valve body. Stuffing is arranged between the valve rod and the valve body. A stuffing gland is arranged on the valve rod in a sleeved mode. The stuffing is tightly pressed by the stuffing gland. A positioning piece is arranged at the portion, above the stuffing gland, of the valve rod in a sleeved mode. The positioning piece comprises a sleeved connecting part and a stop part. A polygon-shaped through hole is formed in the sleeved connecting part. The sleeved connecting part of the positioning piece and the polygon-shaped through hole of the sleeved connecting part are connected on the valve rod in a sleeved mode. The cross section of the position, connected with the sleeved connecting part in the sleeved mode, of the valve rod is matched with the polygon-shaped through hole in shape. At least two stop pillars are arranged at the upper end of the stuffing gland. After the valve rod rotates, when the stop part of the positioning piece respectively reaches the two stop pillars, the valve is respectively in an open state and a closed state. According to the ball valve convenient to control, control over the ball valve is convenient, precise and in place.
Description
Technical field
The utility model relates to a kind of ball valve of convenient control.
Background technique
Conventional ball valve generally comprises valve body and valve gap, and valve body is connected with bonnet flange, is provided with the ball valve flap in the described valve body, described valve body is provided with the valve rod that is connected with the ball valve flap, between valve rod and the valve body filler is set, is with Gland on the valve rod, Gland presses filler.The Joystick that disposes on the valve rod is often controlled inadequately when the opening and closing valve and is accurately put in place.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ball valve of the convenient control that can make the control of valve convenient, more accurately put in place.
For this reason, the ball valve of the convenient control that the utility model provides, comprise valve body and valve gap, valve body is connected with bonnet flange, be provided with the ball valve flap in the described valve body, described valve body is provided with the valve rod that is connected with the ball valve flap, between valve rod and the valve body filler is set, be with Gland on the valve rod, Gland presses filler, be with location piece on the valve rod of described Gland top, described belled part and the gear portion of comprising, described belled part has the polygonal through hole, the belled part of described location piece is socketed on the valve rod with its polygonal through hole, the sectional shape of the position of described valve rod and belled part socket and polygonal through hole coupling, described Gland upper end has at least two gear posts, and the gear of location piece partly was clipped to when reaching on two gear posts and makes valve be in the state of opening and closing respectively after described valve rod rotated.
In the utility model, be socketed with location piece on the valve rod, because the position of location piece and valve rod socket is polygonal, therefore location piece can only rotate with valve rod, and valve rod also can't rotate when location piece is blocked, owing to have two gear posts at the utility model valve body, when gear post present position just during the opening and closing position of corresponding flap, valve just is in opening state when making location piece run into the gear post of corresponding enable possition as long as valve rod rotates, and valve just is in closed condition when making location piece run into the gear post of corresponded closed positions as long as valve rod rotates.When restriction by location piece closes if can allowing the operator obviously feel when to open, thereby make more convenient to operately, and more accurately puts in place.
Description of drawings
The conveniently structure cross-sectional schematic of the ball valve of control that Fig. 1 provides for the utility model;
Fig. 2 is that the location piece of ball valve among Fig. 1 is arranged on the structural plan schematic representation on the valve body.
Embodiment
As Fig. 1, shown in 2, the ball valve of the convenient control that the utility model provides, comprise valve body 1 and valve gap 2, valve body 1 is connected with valve gap 2 flanges, be provided with ball valve flap 3 in the described valve body 1, described valve body 1 is provided with the valve rod 4 that is connected with ball valve flap 3, between valve rod 4 and the valve body 1 filler is set, be with Gland 5 on the valve rod 4, Gland 5 presses filler, be with location piece 6 on the valve rod 4 of described Gland 5 tops, described location piece 6 comprises belled part 7 and gear portion 8, described belled part 7 has polygonal through hole 9, polygonal through hole on the location piece 69 is rectangular opening in the present embodiment, location piece 6 belled position cross sections on the described valve rod 4 are rectangular, the belled part 7 rounded distributions of described location piece 6, the gear portion 8 of described location piece 6 is triangular in shape, gear portion 8 adopts the cambered surface transition with the side, joint of belled part 7, the belled part 7 of described location piece 6 is socketed on the valve rod 4 with its polygonal through hole 9, described valve rod 4 mates with sectional shape and the polygonal through hole 9 of the position of belled part 7 sockets, described Gland 5 upper ends have at least two gear posts 10, and the gear portion 8 that described valve rod 4 rotates back location piece 6 makes valve be in the state of opening and closing respectively when arriving on two gear posts 10 respectively.In the present embodiment, Gland 5 extends first joint 11 to side, on the described valve body to having second joint 12 by first joint 11, offer the bolt hole of mutual coupling on described first joint 11 and second joint 12, first joint 11 is connected by bolt mechanism with second joint 12.
