Abstract
The utility model provides a ball relief valve, and belongs to the technical field of design and manufacturing of ball valves. A valve element is arranged inside a valve body. Two sides of an outer valve-rod sleeve are provided with transverse stop blocks, and the upper portion of each transverse stop block is provided with a vertical stop block. Vertical stop block sliding grooves are formed in two sides inside a rotating handle. Transverse stop block sliding grooves are formed inside the rotating handle and provided with transverse stop block baffles. After the ball relief valve is assembled, the vertical stop blocks are located inside the vertical stop block sliding grooves, and the transverse stop blocks are located inside the transverse stop block sliding grooves. When the ball relief valve is closed, the transverse stop blocks are blocked by the transverse stop block baffles, the transverse stop blocks are restricted under the pressure of a spring, and the handle cannot be rotated freely. When the ball relief valve is opened, the handle is pressed down, the transverse stop blocks break away from the baffles and enter the transverse stop block sliding grooves, and then the handle is rotated. The transverse stop block also plays a role in restraining the handle from being rotated by 90 degrees. The ball relief valve is simple in structure, reasonable in design, and particularly suitable for chemical hazard conveying pipelines or containers. The ball relief valve cannot be opened when the rotating handle is touched by ordinary external force or people accidentally, and accident potential is eliminated.
Description
Technical field
The utility model belongs to design and the manufacturing technology field of ball valve.
Background technique
The ball valve using in production reality is at present all to consist of valve body, spherical valve core and handle with sleeve.Be in operation by the switch of handle with sleeve control valve.It is simple in structure, and it is also convenient to use, very practical on safer generic media delivery line.But its shortcoming is by the direct control switch of handle, in external force or artificial casual situation, touch handle, just easily make valve opening.If in pipeline be generic media, the large problem of nothing, as being that Hazardous Chemical Substances easily causes the generation of security incident in pipeline.For keeping the safety in production or transporting, leave very large hidden danger.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of safer ball valve, and particularly suitable, carrying on Hazardous Chemical Substances pipeline or container, eliminates safe hidden trouble effectively.
The utility model is to address the above problem taked technological scheme to be; In valve body with spool.On spool top with valve rod.On valve rod top, be set with a spring.At the top of valve rod with a retaining screw, on valve rod with handle with sleeve.Central part at handle with sleeve has a gland.On the both sides of valve rod overcoat with strut rail piece, on the top of strut rail piece with perpendicular block.In handle with sleeve, both sides are with perpendicular block chute.In handle with sleeve, week is with strut rail piece chute, on strut rail piece chute, with strut rail piece baffle plate.After the utility model assembling, perpendicular block is positioned at perpendicular block chute, and strut rail piece is in strut rail piece chute.While closing, strut rail piece is blocked by strut rail piece baffle plate, at the pressure bottom rail block of spring, is confined, and handle can not arbitrarily rotate.During Open valve, handle is depressed, made strut rail piece depart from baffle plate, enter in strut rail piece chute, then handle with sleeve.Strut rail piece baffle plate also plays the 90 degree effects of restriction rotatable handle.The utility model is simple in structure, reasonable in design, and this product is specially adapted to Hazardous Chemical Substances delivery line or container containing.While touching handle with sleeve in general external force or artificial casual situation, can, by valve opening, not eliminate accident potential yet.For safety in production is given security.Solved the problem that existing use product exists
