Abstract
The utility model discloses a valve opening/closing device which comprises a support, wherein an upright bar is rotatably connected with the support, and an operating handle and a three-jaw plug which are positioned at two sides of the support are arranged at two ends of the upright bar respectively. A fastening bolt is connected with the support in a thread manner, the fastening bolt is vertical to the upright bar and the fastening bolt and the upright bar are positioned in the same plane, and a fastening nut positioned outside the support is arranged on the fastening bolt. When the valve is opened/closed, the support is placed on the ground, the three-jaw plug is inserted in a hand wheel of the valve, the three-jaw plug is used for rightly blocking three radial connecting bars on the hand wheel of the valve, the operating handle is rotated, the hand wheel of the valve is driven to rotate through the upright bar, and thus the aim of opening/closing the valve can be easily achieved. When the upright bar needs to be fixed, the fastening bolt is rotated to ensure that the inner end of the fastening bolt supports against the upright bar for locking the upright bar, and then the fastening nut is screwed down and the fastening bolt is fixed. The valve opening/closing device has the advantages of simple structure, easiness in manufacture, low manufacture cost, and convenience in operation; and the labor intensity of operators is fully reduced.
Description
Technical field
The utility model belongs to the industrial machinery technical field, relates in particular to a kind of valve opening and closing device.
Background technology
Existing a lot of valve and operating surface not in sustained height, such as the valve of pipeline is arranged on subsurface, the handwheel of frequent operation valve very inconvenient, and labour intensity is large.
The utility model content
The utility model is in order to solve weak point of the prior art, provides a kind of easy operating valve and operating surface not at the valve opening and closing device of sustained height.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: valve opening and closing device, comprise support, and be rotatably connected to vertical rod on support, vertical rod two ends are respectively equipped with operating grip and the three-jaw plug that is positioned at the support both sides.
The fastening bolt that has been threaded on described support, fastening bolt is vertical with vertical rod and at grade, fastening bolt is provided with the clamp nut that is positioned at the support outside.
Adopt technique scheme, when opening and closing valve, with stentplacement on the ground, the three-jaw plug is inserted in the handwheel of valve, the three-jaw plug just in time blocks on the handwheel of valve three radially connecting rods, the rotating operation handle by the hand wheel rotating of vertical rod band movable valve, so just reaches the purpose that opens and closes valve very like a cork.With vertical rod fixedly the time, the rotation fastening bolt makes its inner top press vertical rod that vertical rod is locked, and then clamp nut is tightened fastening bolt is fixed when needs.
The utility model is simple in structure, be easy to make, low cost of manufacture, easy to operate, fully reduced operating personnel's labour intensity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, valve opening and closing device of the present utility model comprises support 1, is rotatably connected to vertical rod 2 on support 1, and vertical rod 2 two ends are respectively equipped with operating grip 3 and the three-jaw plug 4 that is positioned at support both sides Shang Xia 1.The fastening bolt 5 that has been threaded on support 1, fastening bolt 5 is vertical with vertical rod 2 and at grade, fastening bolt 5 is provided with the clamp nut 6 that is positioned at support 1 outside.
When opening and closing valve 7, support 1 is placed on ground 8, three-jaw plug 4 is inserted in the handwheel 9 of valve 7, three-jaw plug 4 just in time blocks on the handwheel 9 of valve 7 three radially connecting rods, then the rotating operation handle 3, rotate by the handwheel 9 of vertical rod 2 with movable valve 7, so just reach very like a cork the purpose that opens and closes valve 7.With vertical rod 2 fixedly the time, rotation fastening bolt 5 makes its inner top press vertical rod 2 with vertical rod 2 lockings, then clamp nut 6 is tightened fastening bolt 5 fixing when needs.
