Abstract
The controlled lockset of manual ball valve, comprise upper collet and lower locking plate, described lower locking plate is provided with the valve rod fixed hole coincide with valve rod shape, lower locking plate is provided with the notch staggered with stuffing box packing bolt position, lower locking plate is positioned at valve rod fixed hole bilateral symmetry and is provided with lower lock-receiving aperture, the line of two lower lock-receiving aperture and valve rod fixed hole is 90 °; Circular hole is provided with in the middle of described upper collet, upper collet is positioned at both sides, middle circle hole and is arranged with filler hold-down bolt hole and upper lock-receiving aperture from the inside to the outside, described circular hole, filler hold-down bolt hole and upper lock-receiving aperture are located on the same line, and between lower lock-receiving aperture with valve rod fixed hole on Distance geometry lock-receiving aperture equal with the distance of middle circular hole.Beneficial effect is: structure is simple, easy to operate, and valve all exists with lower locking plate the lock-receiving aperture overlapped at open and close state upper collet, utilizes common padlock by valve at specified position, thus guarantees production safety.
Description
Technical field
The utility model relates to the controlled lockset of a kind of manual ball valve.
Background technique
Production scene needs manual ball valve to pin due to security reason, prevents valve from being operated.The HWO valves such as common stop valve, gate valve can by tying up handwheel with iron chains and valve pins by the form adding padlock, but for manual ball valve because its operating grip is dismountable, itself does not possess pinning function.
Summary of the invention
It is simple, easy to operate that the technical problems to be solved in the utility model is to provide a kind of structure, can guarantee the controlled lockset of the manual ball valve of production safety.
Technical solution of the present utility model is:
The controlled lockset of manual ball valve, comprise upper collet and lower locking plate, its special way is: described lower locking plate is provided with the valve rod fixed hole coincide with valve rod shape, lower locking plate is provided with the notch staggered with stuffing box packing bolt position, lower locking plate is positioned at valve rod fixed hole bilateral symmetry and is provided with lower lock-receiving aperture, the line of two lower lock-receiving aperture and valve rod fixed hole is 90 °; Circular hole is provided with in the middle of described upper collet, upper collet is positioned at both sides, middle circle hole and is arranged with filler hold-down bolt hole and upper lock-receiving aperture from the inside to the outside, described circular hole, filler hold-down bolt hole and upper lock-receiving aperture are located on the same line, and between lower lock-receiving aperture with valve rod fixed hole on Distance geometry lock-receiving aperture equal with the distance of middle circular hole.
The beneficial effects of the utility model are: structure is simple, easy to operate, lower locking plate utilize the valve rod fixed hole of himself can be enclosed within valve rod with valve rod synchronous axial system; Upper collet is pressed on lower locking plate, utilizes the stuffing box packing bolt of self of ball valve to be fixed on valve body by upper collet, is also pressed in the middle of lower locking plate and valve body by upper collet simultaneously.So no matter valve is that open state or off status upper collet all exist with lower locking plate the lock-receiving aperture overlapped, and utilizes common padlock by valve at specified position, thus guarantees production safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of upper collet;
Fig. 3 is the structural representation of lower locking plate;
Fig. 4 is locking state schematic diagram of the present utility model.
In figure: 1-upper collet, locking plate under 2-, 3-valve rod, 4-ball valve, 101-circular hole, the upper lock-receiving aperture of 102-, 103-filler hold-down bolt hole, 201-valve rod fixed hole, lock-receiving aperture under 202-, 203-notch.
Embodiment
As shown in Figure 1-Figure 3, the controlled lockset of this manual ball valve, comprise upper collet 1 and lower locking plate 2, described lower locking plate 2 is provided with the valve rod fixed hole 201 coincide with valve rod shape, lower locking plate 2 is provided with the notch 203 staggered with stuffing box packing bolt position, lower locking plate 2 is positioned at valve rod fixed hole 201 bilateral symmetry, and to be provided with the lower lock-receiving aperture of lower lock-receiving aperture 202, two 202 with the line of valve rod fixed hole 201 be 90 °; Circular hole 101 is provided with in the middle of described upper collet 1, upper collet 1 is positioned at both sides, middle circle hole 101 and is arranged with filler hold-down bolt hole 103 and upper lock-receiving aperture 102 from the inside to the outside, described circular hole 101, filler hold-down bolt hole 103 and upper lock-receiving aperture 102 are located on the same line, and between lower lock-receiving aperture 202 with valve rod fixed hole 201 on Distance geometry lock-receiving aperture 102 equal with the distance of middle circular hole.
As shown in Figure 4, lower locking plate 2 utilize the valve rod fixed hole 101 of himself can be enclosed within valve rod 3 with valve rod 3 synchronous axial system; Upper collet 1 is pressed on lower locking plate 2, utilizes the stuffing box packing bolt of self of ball valve 4 to be fixed on by upper collet 1 on the valve body of ball valve 4, is also pressed in by upper collet 1 in the middle of lower locking plate 2 and valve body simultaneously.So no matter valve is that open state or off status upper collet 1 all exist with lower locking plate 2 lock-receiving aperture overlapped, and utilizes common padlock by valve at specified position, thus guarantees production safety.
