Description
Technical field
The utility model belongs to valve field, particularly a kind of long handle ball valve.
Background technique
The working principle of ball valve is to make valve unimpeded or inaccessible by rotating sphere core.Ball core, because the diameter of fluid passage is excessive, causes the intensity of ball core to reduce, thus affects the working life of ball valve.The rotation of valve rod has driven the rotation of ball core, but the connection of valve rod and ball core is for being rigidly connected, because the lifting surface area between valve rod and ball core is little, causes the wearing and tearing of valve rod comparatively large, thus reduces the working life of ball valve.In addition, ball valve control switch has been come by long handle, and traditional long handle does not meet body mechanics's principle, wasting time and energy, can not control the folding of ball valve timely and effectively when controlling folding.
