Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the present invention.
Fig. 3 is a bottom view of the present invention.
Fig. 4 is a schematic structural view of the top ring.
In the figure: sleeve 1, end plate 2, rotatory power arm 3, support frame 4, apical ring 5, threaded rod 6, ring 7.
Detailed Description
The following further describes the embodiments of the present invention with reference to the attached drawings:
as shown in fig. 1-3, a simple opening and closing tool for a large gate valve comprises a sleeve 1, an end plate 2, a rotary power arm 3, a support frame 4 and a top ring 5, wherein the end plate 2 is sleeved outside one end of the sleeve 1, inner threads are arranged on the inner wall of the sleeve 1, and the inner threads on the inner wall of the sleeve 1 are matched with the outer threads of a gate valve rod.
The outer wall of the sleeve 1 close to the end plate 2 is radially connected with a rotary power arm 3, the rotary power arm 3 is made of a steel pipe, the outer diameter of the steel pipe is not less than 30mm, and the length of the rotary power arm 3 is greater than 500 mm.

The top ring 5 is symmetrically arranged, and the top ring 5 comprises a threaded rod 6 and a circular ring 7 which are of an integrated structure.
Examples
The utility model provides a simple and easy switching instrument of large-scale gate valve, includes sleeve 1, end plate 2, rotatory power arm 3, support frame 4, apical ring 5, and end plate 2 is established to the outside cover of sleeve 1's one end, and 1 inner wall of sleeve is equipped with the internal thread, the internal thread of 1 inner wall of sleeve and the thread fit of gate valve rod.
The outer wall of the sleeve 1 close to the end plate 2 is radially connected with a rotary power arm 3, the rotary power arm 3 is made of steel pipes, the outer diameter of each steel pipe is 35mm, and the length of the rotary power arm 3 is 550 mm.
The rotary power arms 3 are uniformly distributed on the circumference, the rotary power arms 3 are connected through a support frame 4, and the end face of the end plate 2 is in threaded connection with a top ring 5. Two top rings 5 are symmetrically arranged, and the top rings 5 comprise a threaded rod 6 and a circular ring 7 which are of an integrated structure.
When the electric head of the gate valve breaks down or the valve rod is too low, the electric head is dismantled. The sleeve 1 of the above device is aligned with the stem of the gate valve and is rotatably connected to the stem, and the top ring 5 is supported on the outer surface of the housing outside the stem. The operator manually moves the rotary power arm 2 to lift or lower the gate valve. And taking out the device after the operation is finished.
Above utility model, to the ordinary technical personnel in this technical field, can also be right without deviating from the principle of the utility model, these improve and decorate and also fall into the protection scope of the utility model claims.
