Abstract
The utility model discloses a ball body assembly for a wear-resisting semi-lined ceramic ball valve. The ball body assembly comprises a valve cover, wherein a valve rod hole is formed in the middle of the valve cover; a valve rod is mounted in the valve rod hole in a matched manner; filler is filled between the valve rod and the valve rod hole; a filler gland is arranged at the upper end of the filler; a ball body is fixedly mounted at the lower end of the valve rod and is formed by spraying a hard ally material on a metal material; two sides of the ball body are contacted with a valve seat; and the valve seat is made of wear-resisting ceramic. The ball body assembly disclosed by the utility model has the advantages of long service life and improved impact resistance.
Description
Technical field
The utility model relates to a kind of wear-resistant ceramic ball valve spheroid assembly that partly serves as a contrast.
Background technique
It is a lot of to work the ball valve kind of blocking medium in pipeline, hard sealed eccentric ball valve and soft seal constant-current type ball valve are arranged, the sealing of hard sealed constant-current type ball valve is metal to metal, phase-contact surface meeting phase mutual friction after long-time the use, make and be sealed with certain leakage, the sealing of soft seal constant-current type ball valve is metal pair rubber, phase-contact surface can the phase mutual friction after long-time the use, sealing can reach zero leakage, the defectives such as the metallic material spheroid in the prior art valve exists working life short, and impact resistance is low.
The model utility content
The utility model provides a kind of long service life, the wear-resistant ceramic ball valve spheroid assembly that partly serves as a contrast of shock-resistant raising.
The utility model technical solution problem provides following scheme:
A kind of wear-resistant ceramic ball valve spheroid assembly that partly serves as a contrast, comprise valve gap, the middle part of described valve gap is provided with valve rod hole, cooperate in the described valve rod hole valve rod is installed, be filled with filler between described valve rod and the valve rod hole, the upper end of described filler is provided with Gland, and the lower end of described valve rod is installed with spheroid, described spheroid adopts metallic material coated with hard alloy material to make, and the both sides of described spheroid contact with valve seat.
Described valve seat adopts wear-resistant ceramic to make.
Spheroid of the present utility model adopts metallic material coated with hard alloy, can effectively guarantee rigidity and the impact of spheroid, and valve seat is pottery, and its hardness is higher than spheroid, produces difference of hardness, and sealability is better.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of wear-resistant ceramic ball valve spheroid assembly that partly serves as a contrast, comprise valve gap, the middle part of described valve gap 1 is provided with valve rod hole 2, and described valve rod hole 2 interior cooperations are equipped with valve rod 3, be filled with filler 4 between described valve rod 3 and the valve rod hole 2, the upper end of described filler 4 is provided with Gland 5, and the lower end of described valve rod 3 is installed with spheroid 6, and described spheroid 6 adopts metallic material coated with hard alloy material to make, the both sides of described spheroid 6 contact with valve seat 7, and described valve seat 7 adopts wear-resistant ceramic to make.
Claims (2)
1. wear-resistant ceramic ball valve spheroid assembly that partly serves as a contrast, comprise valve gap, it is characterized in that: the middle part of described valve gap is provided with valve rod hole, cooperate in the described valve rod hole valve rod is installed, be filled with filler between described valve rod and the valve rod hole, the upper end of described filler is provided with Gland, and the lower end of described valve rod is installed with spheroid, described spheroid adopts metallic material coated with hard alloy material to make, and the both sides of described spheroid contact with valve seat.
