Abstract
The utility model provides a scalable ratchet F spanner, includes ratchet connection structure, scalable F type centre gripping module, steel extension connecting sleeve, and wherein scalable F type centre gripping module is connected to ratchet connection structure below, and extension connecting sleeve is connected to ratchet connection structure right-hand member, and extension bar is connected to steel extension connecting sleeve right-hand member.
Description
Technical Field
This technical manual valve field, concretely relates to scalable ratchet F spanner.
Background
Various industrial production process systems including nuclear power plants, hydraulic power plants and coal and gas production plants are provided with manual valves, and some valves bring great difficulty to operators due to the reasons of narrow operation positions, large operation mechanisms and the like, can not be operated to required positions rapidly under emergency conditions, and have hidden dangers of threatening personal safety and equipment safety. Present manual valve operating means generally is steel "F spanner", and its characteristics are sturdy and durable but can't satisfy the work demand under the different situation, and the valve of equidimension not needs to be equipped with the spanner of different specifications, to the narrow and small valve of operating position unable use even, to operating environment comparatively abominable (for example high temperature, irradiation etc.), and need quick, the accurate valve of accomplishing the operation, present operating means can not satisfy actual work demand yet.
Disclosure of Invention
The invention aims to: the design is a manual valve wrench which has wider application range, is more convenient to carry and saves more labor in operation, so that the operation efficiency of the manual valve of the industrial process system is improved.
The technical scheme of the invention is as follows: the utility model provides a scalable ratchet F spanner, includes ratchet connection structure, scalable F type centre gripping module, steel extension connecting sleeve, and wherein scalable F type centre gripping module is connected to ratchet connection structure below, and extension connecting sleeve is connected to ratchet connection structure right-hand member, and extension bar is connected to steel extension connecting sleeve right-hand member.
The retractable F-shaped clamping module is detachable.
The size of the 'F opening' of the telescopic F-shaped clamping module can be adjusted.
The adjusting range is 5cm-15 cm.
The lengthened connecting sleeve comprises two sections of structures which are mutually sleeved and can be detached.
The invention has the following remarkable effects: the novel wrench is convenient to carry, wide in application range, simple to operate and firm and reliable in structure. 1. The newly-added ratchet mechanism can realize the separation of the clamping module and the handle, and is suitable for the operation and use in narrow space and limited area. 2. The clamping F port can be adjusted according to the size of the valve wheel disc, and the valve can be suitable for various valves in large, medium and small sizes by carrying a wrench. 3. The operating handle can be lengthened or disassembled by using the sleeve, is suitable for being used in large-torque occasions, and is convenient to carry.

Detailed Description
The utility model provides a scalable ratchet F spanner, includes ratchet connection structure 1, scalable F type centre gripping module 2, steel extension connecting sleeve 3, and wherein scalable F type centre gripping module 2 is connected to ratchet connection structure 1 below, and scalable F type centre gripping module 2 can be dismantled, and the size of scalable F type centre gripping module 2's "F mouth" is adjustable, and the control range is 5cm-15 cm. The right end of the ratchet wheel connecting structure 1 is connected with the lengthened connecting sleeve 3, and the lengthened connecting sleeve 3 comprises two sections of structures which are mutually sleeved and can be detached. The right end of the steel lengthening connecting sleeve 3 is connected with an lengthening rod 4.
Specific method of use
1) After the size of the valve needing to be operated is preliminarily judged, the size of the F-shaped opening is adjusted by using threads, and the telescopic F-shaped clamping module 2 is connected into the ratchet wheel connecting structure 1.
2) The valve wheel disc to be operated is clamped at the opening F and swings towards the same direction (clockwise is closed and anticlockwise is open)
3) If the moment is found to be large during operation, the extension rod 4 can be connected by extending the connecting sleeve 3, each section is 15cm, and at most 2 sections can be connected.
4) After the operation is completed, the wrench is removed, and the retractable F-clamp module 2 is removed and loaded into the toolbox.
Claims (5)
