Abstract
The utility model relates to an inner core of a ceramic coated ball type valve, which primarily comprises a ball core and a ball bed; wherein, the matching surface of the ball core and the ball bed is provided with certain gap, and is respectively provided with a ceramic coating layer. By using the ceramic coating layer provided in the technical proposal, the wearing and corrosion resistance of the matching surface of the ball core and ball bed is improved, thereby further enhancing the sealing effect between the ball core and the ball bed, increasing the bearing capacity and prolonging the service lift of the ball valve greatly.
Description
Technical field
The utility model relates to a kind of ball valve, is meant the ceramic spraying ball valve inner core in a kind of ball valve especially.
Background technique
Ball valve inner core in prior art mostly is to adopt metallic material to make, the ball seat that a spot of ball valve inner core is also arranged is to adopt polytetrafluoroethylmaterial material to make, described inner core is to be made of ball core and ball seat, ball core and ball seat are in the use that cooperatively interacts in application, make the outer surface of ball core and the internal surface of ball seat wearing and tearing and corrosion phenomenon occur especially easily, cause the seal failure between ball core and ball seat, and then directly have influence on the working life of ball valve.
Summary of the invention
At the problem and shortage easy to wear and corrosion-prone between existing ball core of inner core in the above-mentioned prior art and ball seat, the utility model provides a kind of ceramic spraying ball valve inner core.
The utility model is achieved in that a kind of ceramic spraying ball valve inner core, it mainly includes ball core and ball seat, cooperatively interacting of described ball core and ball seat is provided with certain clearance between face, be respectively arranged with the ceramic spraying layer on the face that cooperatively interacts of described ball core and ball seat.
The gap that is provided with between face that cooperatively interacts of described ball core and ball seat is 0.2mm to 1mm, the ceramic spraying layer thickness 0.1mm to 0.5mm that is provided with respectively on the face that cooperatively interacts of described ball core and ball seat.
The beneficial effects of the utility model are: by the wear-resisting corrosion resistance that undermines that the ceramic spraying layer has improved fitting surface between ball core and ball seat is set, further improved the sealing effect between ball core and ball seat, strengthen bearing capacity, prolonged the working life of ball valve greatly.

Embodiment
Be described further below in conjunction with accompanying drawing the utility model.
The ceramic spraying ball valve inner core that the utility model relates to, it mainly includes ball core 3 and ball seat 1, cooperatively interacting of described ball core 3 and ball seat 1 is provided with certain clearance between face, be respectively arranged with ball core ceramic spraying layer 2 and ball seat ceramic spraying layer 4 on the face that cooperatively interacts of described ball core 3 and ball seat 1.
The gap that is provided with between face that cooperatively interacts of described ball core 3 and ball seat 1 is 0.2mm to 1mm, and the ball core ceramic spraying layer 2 that is provided with respectively on the face that cooperatively interacts of described ball core 3 and ball seat 1 and the thickness of ball seat ceramic spraying layer 4 are 0.1mm to 0.5mm.
The utility model is through the pyrolytic coating method, and with the ceramic spraying layer that the nanometer scale ceramics powder is made, the firm sealing surfaces between face of cooperatively interacting that is fixed on Metal Ball core and ball seat is through grinding the precision combination that reaches two contact surfaces.
