Description

Special-shaped spanner is assisted to valve hand wheel

Technical Field

The utility model belongs to the field of auxiliary wrenches, and particularly relates to an auxiliary special-shaped wrench for a valve hand wheel.

Background

In the running process of the town gas pipe network, various valves can be opened or closed and other conventional operations are carried out due to production requirements. In actual operation, the valve is not easy to open or close due to various reasons, such as the pressure energy of the medium, the structure and size of the valve, and the valve is not operated for a long time. If the pressure level is high, the valve is opened under the conditions that one side of the valve is subjected to high pressure and the pressure on the other side of the valve is low or no pressure exists, so that the operation time and the emergency treatment time are delayed, and the abnormal production condition cannot be controlled at the first time under the serious condition. The F wrench is an ideal tool for opening and closing the valve and maintaining and repairing the valve, and is a special wrench for the valve. However, in the using process, the traditional F wrench has some defects, and sometimes has the problems of labor and time waste in operation and the like. In order to solve the problems, the structure of the F wrench is improved, so that the F wrench is more convenient, labor-saving and safer to operate.

When traditional F spanner used, the edge that utilizes two cylinder short handles of spanner front end to block the valve hand wheel rotated the valve hand wheel through pulling the handle, can reach the purpose of switch valve, has lengthened the arm of force through F spanner like this, can be lighter rotation to difficult pivoted valve hand wheel, reaches laborsaving purpose. The F wrench is simple to manufacture and convenient to use, and is widely applied to industries such as petroleum, chemical engineering, machinery and the like at present. And various F wrenches suitable for field application, such as an explosion-proof F wrench, are manufactured, and a good effect is achieved. On the other hand, however, we have found the following problems with the conventional F wrench in daily work:

the front ends of the F wrenches are two cylindrical surfaces, the edges of a hand wheel are clamped through the F wrenches during working, the F wrenches are not tightly contacted with the hand wheel, if a large force is suddenly applied to a handle occasionally and the force application direction is deviated, the F wrenches are easy to slip from the hand wheel, so that potential safety hazards exist, and even a human body can be hit, and accidents are caused.

2. The structure of traditional F spanner has decided that the atress direction of spanner can not be identical completely with the circumferential direction of valve hand wheel, takes place to exert oneself the direction deviation easily, and the spanner skids and drops.
