Abstract

The utility model provides an improved valve wrench, belonging to the field of hardware tools. The improved valve wrench is characterized in that the wrench comprises three teeth with threads on a triangular head (5), a long handle (6) and a rotating handle (7), wherein the rotating handle (7) is vertically mounted on the long handle (6). The shapes of the triangular head (5) and the long handle (6) are flat, so that the anti-bending strength is increased; the threads (4) on the three teeth can play an anti-skid role; the triangular head (5) can prevent the long handle from rotating on the two sides on a valve handle; and a valve can be quickly opened or closed by holding the rotating handle (7) with the hand and rotating the rotating handle (7) continuously. The improved valve wrench provided by the utility model is extensively applicable to operation of pipeline valves in electric power plants, petroleum, chemical engineering and other industries, so that the operation of opening or closing the valve is safe, time-saving and labor-saving, and the operation efficiency is further improved.

Description

A kind of modified tap wrench

Technical field

The utility model belongs to hardware & tools, relates to a kind of spanner, and is particularly related to a kind of tap wrench.

Background technology

At present industries such as power plant, oil, chemical industry need a large amount of pipeline valve control operations, because economical, the durability of manually-operated gate and the flexibility controlled are still adopted by most of enterprises; These manually-operated gates are depended merely on hand and are rotated handwheel, often are difficult to open or close, though the simple and easy spanner that has " F " shape two tooth spanners or enterprise oneself to make on the market; But lack non-skid feature, tap wrench is difficult to be fixed on fast on the handwheel, makes troubles to the operator; Can not open rapidly or valve-off; Even bring personal injury to the operator, though existing trigonocephalia three tooth spanners can play the anti-skidding effect of part, it is still inconvenient to operate.These tap wrenches are pulled maximum angle and are had only 180 degree in addition, and controlled valve whenever rotates to an angle, and just need make a short pause; Conversion spanner position; Inevitable so consuming time, efficient is low, and is very inconvenient for opening or closing valve during especially burst accident is speedily carried out rescue work in the commercial production fast.

Summary of the invention

The utility model has proposed a kind of simple in structure, easy to operate modified trigonocephalia three tooth tap wrenches to the defective of existing tap wrench technology.

The technical scheme of the utility model is:

A kind of modified trigonocephalia three tooth tap wrenches; Form by three on the trigonocephalia 5 threaded tooth I 1, tooth II 2, tooth III 3, long handle 6, rotary handle 7; Trigonocephalia 5 and long handle 6 are flat pattern, increase flexural strength, and the screw thread 4 on three teeth plays anti-skidding effect; Rotary handle 7 is vertically mounted on the long handle 6, and rotary handle 7 can be assembled or dismantle according to actual conditions.Tooth I 1, tooth II 2, tooth III 3, trigonocephalia 5, long handle 6 adopt contour forging technique, and be one-body molded.The material of spanner is selected the metal or metal alloy that intensity is big, toughness is strong and wear-resisting for use.

The beneficial effect of the utility model:

Trigonocephalia 5 prevents long handle both sides rotation on valve handle, and the screw thread 4 on the tooth plays anti-skidding effect simultaneously.

Hold rotary handle 7 clockwise or be rotated counterclockwise, can open or close valve continuously apace, make that the operation of controlled valve is time saving and energy saving, raise the efficiency.

Description of drawings

Fig. 1 is the three-dimensional view of a kind of modified tap wrench of the utility model:

1---tooth I, 2---tooth II, 3---tooth III, 4---screw thread, 5---trigonocephalia, 6---long handle, 7---rotary handle

The specific embodiment

A kind of modified tap wrench of the utility model is done further to specify through the specific embodiment below in conjunction with accompanying drawing 1:

Valve handle is stuck between a kind of tooth I 1 and tooth II 2, tooth III 3 of modified tap wrench, tooth I 1 is inboard at valve handle, tooth II 2, the tooth III 3 valve handle outside that coexists; Two faces of trigonocephalia 5 withstand on the valve handle, play the effect of back-up wrench, and clockwise direction is pulled long handle 6; Under the effect of tooth I 1 and tooth II 2, drive the rotation of valve handle clockwise direction, counterclockwise pull long handle 6; Under the effect of tooth I 1 and tooth III 3, drive valve handle and counterclockwise rotate, close or the purpose of Open valve thereby play; Screw thread on tooth I 1, tooth II 2, the tooth III 3 plays the effect that prevents spanner landing from the valve handle; Valve is in a single day loosening, then can hold rotary handle 7 and directly carry out rotating quick closedown or Open valve clockwise or counterclockwise continuously.Rotary handle 7 can be assembled or dismantle according to actual conditions, is convenient to practical operation, and tooth I 1, tooth II 2, tooth III 3 can be cylinder or oval cylinder.In order to strengthen the counter-bending ability of spanner, the material of spanner is selected the metal or metal alloy that intensity is big, toughness is strong and wear-resisting for use.

Claims
