It is miscellaneous purpose of the utility model is to solve the leakproofness existed in the prior art between sphere and valve seat is poor
Matter is easy a kind of wear resistance ball valve for entering from valve rod gap to the disadvantage in valve body, and proposing.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of wear resistance ball valve, including valve body are designed, sphere is equipped in the valve body, is located at the sphere in the valve body
Two sides are fixed with medium channel, and valve rod is fixed on the valve body, and one end of the valve rod extends to the valve body
Inside, one end that the valve rod is located at the inside of the valve body are fixed on the sphere, and the sphere is located on the valve body
Outside be symmetrically arranged with four grooves, movable block is equipped in each groove, the two sides of each groove are equipped with cunning
Slot, sliding block is slidably connected in each sliding slot, and each sliding block is each attached to described far from one end of the sliding slot
Movable block is equipped with spring in each groove, and one end of each spring is each attached on the groove, each described
Spring is each attached on the movable block far from one end of the groove, and each one end of the movable block far from the spring is equal
It is fixedly connected with block, the upper end of each block is fixedly connected to the first gasket, close institute on each block
The side for stating sphere is connected with valve seat, and the side of the close sphere is fixedly connected to the second sealing on each block
Pad.
Preferably, the valve rod is connected far from one end of the sphere with rotating device.
Preferably, first gasket and second gasket are rubber pad.
Preferably, the movable block and the block are structure as a whole.
The utility model proposes a kind of wear resistance ball valve, beneficial effect is: the utility model passes through spring structure and the
Two gasket structures, after rotating sphere, spring-compressed generates elastic force, block will be pushed, so that the second gasket on block
It is fitted closely with sphere, strengthens the sealing between valve seat and sphere, the second gasket structure stops external sundries to stitch from valve rod
The inside of valve body is entered in gap, structure is simple, and sealing effect is good, and impurity cannot be introduced into valve body.
Detailed description of the invention
