Abstract
The utility model discloses a fluorine rubber sealing device of ball valve, comprising a valve seat junk ring 1, a valve seat supporting ring 5, a backstop bolt 3 set on the valve seat junk ring 1, a spring 6 provided between the valve seat and the valve seat, fire-resistant filling 7 set in a groove between the valve seat support ring 5 and the valve seat, and a O-shaped ring and a valve seat O-shaped ring 2 seat in a groove between the valve seat support ring 5 and the valve seat. The utility model is firm can't be damaged easily, and has good sealing property.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of ball valve.
Background technique
Existing soft sealing ball valve adopts engineering plastics such as PTFE NYLON DEVLON or PEEK to add metal support structure mostly.Existing this soft seal, sealing effect is bad, and is insecure.
Summary of the invention
At the shortcoming of existing ball valve sealing device, the utility model provides a kind of fluorine rubber seal arrangement of ball valve.
To achieve these goals, technical solution adopted in the utility model is:
A kind of fluorine rubber seal arrangement of ball valve, comprise valve seat pressure ring 1, valve seat bracing ring 5, valve seat pressure ring 1 is provided with stopping screw 3, be provided with spring 6 between valve seat pressure ring 1 and the valve seat, be provided with fire-proof packing 7 in the groove between valve seat bracing ring 5 and the valve seat, be provided with O shape circle 8 and valve seat O shape circle 2 in the groove between valve seat bracing ring 5 and the valve seat;
Described O shape circle 8 and valve seat O shape circle 2 are fluorine rubber;
The hardness range of described fluorine rubber is 95 °-98 °.
The beneficial effects of the utility model: good airproof performance, firmly, not fragile.
Description of drawings
Fig. 1. the overall schematic of the utility model ball valve.
Fig. 2. structure partial view of the present utility model.
Embodiment
See also its implementation process of description of drawings:
A kind of fluorine rubber seal arrangement of ball valve, comprise valve seat pressure ring 1, valve seat bracing ring 5, valve seat pressure ring 1 is provided with stopping screw 3, be provided with spring 6 between valve seat pressure ring 1 and the valve seat, be provided with fire-proof packing 7 in the groove between valve seat bracing ring 5 and the valve seat, be provided with O shape circle 8 and valve seat O shape circle 2 in the groove between valve seat bracing ring 5 and the valve seat; Described O shape circle 8 and valve seat O shape circle 2 are fluorine rubber; The hardness range of described fluorine rubber is 95 °-98 °.The valve seat bracing ring is an axial float, realizes the sealing of valve when the low pressure by the spring precompressed, and has reasonably adapted to the piston effect of valve seat, relies on the thrust of medium itself to realize high pressure sealing, thereby reaches the purpose of cut-out medium.The beneficial effects of the utility model: good airproof performance, firmly, not fragile.
The utility model patent is fit to the valve of various sizes.
