Abstract
The invention relates to an F-shaped wrench for a valve. The F-shaped wrench comprises a main rod body, an outer barrel and an outer clamping part, wherein an upper wrench head and a lower wrench head are arranged above the main rod body at a certain interval; the outer barrel is arranged on the main rod body in a sleeving way; the outer clamping part is fixed on the outer barrel. According to the scheme of the invention, the upper wrench head and the lower wrench head are combined with the outer clamping part, and the wrench is clamped on a valve hand wheel by using the clamping part to form line contact or multipoint contact on the hand wheel together with the upper wrench head and the lower wrench head, so that the wrench can be stably arranged on the hand wheel in a sleeving way; when the main rod body rotates, the wrench is prevented from slipping from the hand wheel, so that operation is reliable, and a manufacturing process is easy to implement.
Description
Technical field
The present invention relates to a kind of spanner, refer in particular to a kind of valve F type spanner.
Background technology
F spanner is gained the name as English alphabet " F " because of shape of product, F spanner is that equipment is installed, device and overhaul of the equipments, common tool in maintenance work.During use, utilize two of spanner front end spanners to block the edge of valve handle, carrying out rotating valve handwheel by pulling handle, the object of controlled valve can be reached, but in use, find that the edge that spanner blocks handwheel is two-point contact, the contact defective tightness of itself and handwheel, if once in a while unexpected on handle, apply larger power and power thrusts has a deviation time, F spanner is then easy from slippage handwheel, thus there is potential safety hazard, even also may hit human body and see, cause the accident.
Summary of the invention
The present invention seeks to provide one to realize multi-point support to overcome the deficiencies in the prior art, operation is reliable, uses not eely valve F type spanner.
For achieving the above object, the technical solution used in the present invention is: a kind of valve F type spanner, and comprise main rod body, be interval with spanner, lower spanner above described main rod body, described spanner also comprises outer cylinder body and outer Fastener; Described outer cylinder body is socketed in main rod body; Described outer Fastener is fixed on outer cylinder body.
Improve further as the present invention, above described main rod body, be provided with some draw-in grooves; Described outer cylinder body is fixed by screws in draw-in groove, thus realizes being socketed in main rod body.
Improve further as the present invention, the curved body shape of described outer Fastener.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of valve F type spanner of the present invention program, upper and lower spanner and outer Fastener is adopted to combine, utilize Fastener to be clamped on by spanner on valve handle and on handwheel, form linear contact lay or Multi-contact together with upper and lower spanner, what thus spanner can be more firm is enclosed within handwheel, when rotating main rod body, spanner is not easily from slippage handwheel, and operation is reliable, also realizes than being easier to manufacture craft.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of valve F type spanner of the present invention;
Accompanying drawing 2 is the using state schematic diagram of a kind of valve F type spanner of the present invention;
Wherein: 1, main rod body; 2, upper spanner; 3, lower spanner; 4, outer cylinder body; 5, outer Fastener; 6, draw-in groove; 7, screw; 8, valve handle.
detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in accompanying drawing 1,2, be a kind of valve F type spanner of the present invention, comprise main rod body 1, outer cylinder body 4 and outer Fastener 5, above described main rod body 1, be interval with spanner 2, lower spanner 3; Described outer cylinder body 4 is socketed in main rod body 1; Described outer Fastener 5 is fixed on outer cylinder body 4; Some draw-in grooves 6 are provided with above described main rod body 1; Described outer cylinder body 4 is fixed in draw-in groove 6 by screw 7, thus realizes being socketed in main rod body 1; The curved body shape of described outer Fastener 5; Upper and lower spanner and outer Fastener 5 is adopted to combine, utilize outer Fastener 5 to be clamped on by spanner on valve handle 8 and on handwheel, form linear contact lay or Multi-contact together with upper and lower spanner, what thus spanner can be more firm is enclosed within handwheel, when rotating main rod body, spanner is not easily from slippage handwheel, operation is reliable, also realizes than being easier to manufacture craft.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
Claims (3)
1. a valve F type spanner, comprises main rod body, is interval with spanner, lower spanner, it is characterized in that above described main rod body: also comprise outer cylinder body and outer Fastener; Described outer cylinder body is socketed in main rod body; Described outer Fastener is fixed on outer cylinder body.
2. a kind of valve F type spanner according to claim 1, is characterized in that: be provided with some draw-in grooves above described main rod body; Described outer cylinder body is fixed by screws in draw-in groove, thus realizes being socketed in main rod body.
