Abstract
The utility model discloses a flange sealing structure in a float ball valve, which comprises a valve body. The left end of the valve body is provided with an inlet end; an outer flange and a middle flange are respectively arranged at left and right end ports of the inlet end; an installation clamping groove is arranged in the end face of the middle flange; a wound gasket installation groove and an O-shaped sealing ring installation groove are arranged in the side wall of the installation clamping groove; and a wound gasket and an O-shaped sealing ring are respectively and correspondingly arranged in the wound gasket installation groove and the O-shaped sealing ring installation groove. According to the utility model, the sealing performance is strengthened; the possibility of outleakage is avoided; and the flange sealing structure takes effects of saving loss and protecting the environment.
Description
Technical field
The utility model relates to flange seal structure in a kind of floating ball valve.
Background technique
It is a lot of in pipeline, to work the ball valve kind of blocking medium, and hard seal eccentric ball valve and soft seal constant-current type ball valve are arranged, and the sealing that seals the constant-current type ball valve firmly is a metal to metal; The mutual friction of phase-contact surface meeting phase makes to be sealed with certain leakage after long-time the use, and the sealing of soft seal constant-current type ball valve is a metal pair rubber; The long-time back phase-contact surface that uses can the phase mutual friction; Sealing can reach zero leakage, and the flange spirotallic gasket is influenced by pipeline pressure for a long time in the existing technology valve, if do not tighten; Will leak, influence working life.
The model utility content
The utility model provides a kind of performance that has strengthened sealing, has stopped possibility that leak outside, play practice thrift lose and the floating ball valve of environment protection effect in the flange seal structure.
The utility model technical solution problem provides following scheme:
Flange seal structure in a kind of floating ball valve; Comprise valve body; It is characterized in that: the left end of said valve body has entrance point; Be respectively equipped with outward flange and middle flange on the left and right port of said entrance point, the end face of said middle flange is provided with the installation draw-in groove, and the sidewall of said installation draw-in groove is provided with wound gasket mounting groove and O-ring seals mounting groove.
In said wound gasket mounting groove and the O-ring seals mounting groove respectively correspondence wound gasket and O-ring seals are installed.
The flange spirotallic gasket is influenced by pipeline pressure for a long time in the utility model valve, if do not tighten, will leak; Therefore, seal with O ring plays crucial effect, and the utility model is provided with double sealing structure in middle flange position; O shape circle and the sealing of graphite spirotallic gasket; Strengthened the performance of sealing, stopped possibility that leak outside, played to practice thrift and lose and environment protection effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; Flange seal structure in a kind of floating ball valve comprises valve body 1, and the left end of said valve body 1 has entrance point 2; Be respectively equipped with outward flange 3 and middle flange 4 on the left and right port of said entrance point 2; The end face of flange 4 is provided with draw-in groove 5 is installed in said, and the sidewall of said installation draw-in groove 5 is provided with wound gasket mounting groove 6 and O-ring seals mounting groove 7, in said wound gasket mounting groove 6 and the O-ring seals mounting groove 7 respectively correspondence wound gasket 8 and O-ring seals 9 are installed.
Claims (2)
1. flange seal structure in the floating ball valve; Comprise valve body; It is characterized in that: the left end of said valve body has entrance point; Be respectively equipped with outward flange and middle flange on the left and right port of said entrance point, the end face of said middle flange is provided with the installation draw-in groove, and the sidewall of said installation draw-in groove is provided with wound gasket mounting groove and O-ring seals mounting groove.
