Abstract

A kind of valve seat construction of synthetic gas butterfly valve, be made up of valve seat and trim ring, valve seat is arranged on butterfly valve body and is sealed by seal ring, trim ring is positioned at the outside of valve seat and is installed on the circular groove of valve body, and trim ring is provided with adjusting bolt, and adjusting bolt runs through trim ring and top abuts with valve seat, the outer ring of valve seat is provided with flange, the cross section of trim ring is stepped shaft, leaves gap between the ladder surface formed and valve body, and flange is inlaid in described gap.The beneficial effects of the utility model are: the structure of floating valve seat does microdisplacement under the effect of pressure medium, not only can not affect the sealing of valve, simultaneously also can not cause wearing and tearing to valve body, by MEDIA FLOW to restriction, can two way sealed be realized; The flange that valve seat is arranged, and make it to be inlaid between trim ring and valve body, valve seat flange can be prevented, stopped the generation of stuck phenomenon.

Description

A kind of valve seat construction of synthetic gas butterfly valve
Art
The utility model relates to a kind of valve seat construction, particularly relates to a kind of floating valve seat structure.
Background technique
The synthetic gas butterfly valve of current use, its valve seat adopts stationary structure usually, it is stationary fit relation between the external diameter of valve seat and valve seat mounting groove internal diameter, and sealing realizes by front extruding, but the valve plate of this class formation very easily causes the scuffing of two-phase matching trim when opening and rotating, will cause seal failure time serious.The valve seat construction improved is floating type, and usually adopt adjusting bolt to abut valve seat end face and realize, such structure is when valve bears backpressure, and flange phenomenon easily appears in valve seat, causes occurring stuck phenomenon during valve opening and closing.
Model utility content
In order to overcome the above-mentioned shortcoming of existing valve seat construction, the utility model provides a kind of realization to prevent valve seat flange, and can realize two way sealed valve seat construction.
The utility model solves the technological scheme that its technical problem adopts, a kind of valve seat construction of synthetic gas butterfly valve, be made up of valve seat and trim ring, valve seat is arranged on butterfly valve body and is sealed by seal ring, and trim ring arranges along the inner circumferential of valve body and is installed in the circular groove of valve body, and trim ring is positioned on the left of valve seat, adjusting bolt is installed above, adjusting bolt runs through trim ring from left to right and top abuts with valve seat, and the outer ring of valve seat is provided with flange, and flange embeds between trim ring and valve body.
The beneficial effects of the utility model are: the structure of floating valve seat does microdisplacement under the effect of pressure medium, not only can not affect the sealing of valve, simultaneously also can not cause wearing and tearing to valve body, by MEDIA FLOW to restriction, can two way sealed be realized; The flange that valve seat is arranged, and make it to be inlaid between trim ring and valve body, valve seat flange can be prevented, stopped the generation of stuck phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment;
In figure: 1. trim ring; 101. ladder surface; 2. valve seat; 201. flange; 3. seal ring; 4. valve body; 5. annular groove; 6. adjusting bolt.
Embodiment
As shown in Figure 1, a kind of valve seat construction of synthetic gas butterfly valve, be made up of valve seat 2 and trim ring 1, valve seat 2 is arranged on butterfly valve body 4 and is sealed by seal ring 3, and trim ring 1 arranges along the inner circumferential of valve body 4 and is installed in the circular groove 5 of valve body, and trim ring 1 is positioned on the left of valve seat 2, adjusting bolt 6 is installed above, adjusting bolt 6 runs through trim ring 1 from left to right and top abuts with valve seat 2, and the outer ring of valve seat 2 is provided with flange 201, and flange 201 embeds between trim ring 1 and valve body 4.
