Abstract
The utility model provides a disk seat formula wedge gate valve floats, through making inlet valve seat into relocatable form, the medium gets into from the import like this, promote the unsteady disk seat of import, the laminating is on the flashboard, it is sealed to form first way, then the medium promotes the flashboard again and forms the export forced seal, this says sealedly for the second, form through double sealing makes the gate valve sealed more reliable, the design that the disk seat was floated in the import can also prevent that the lumen from stepping up, rise when the lumen pressure anomaly, when lumen pressure is greater than pipeline pressure, lumen pressure can the import float the disk seat backward the face back down, pressure just can unload and put the pipeline the inside like this.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of floating valve A seating Wedge gate valve.
Background technique
Two valve seats of the import and export of the Wedge gate valve of existing routine are all connected together with valve body by welding, promote flashboard by medium during use and form outlet forced seal, such design makes Wedge gate valve just only have a seal structures, thus causing the sealing of Wedge gate valve easily to go wrong, sealing effect is not good.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility modelly provide a kind of floating valve A seating Wedge gate valve.
The technical solution that the utility model adopts is: a kind of floating valve A seating Wedge gate valve, comprise valve body, valve rod, valve gap and flashboard, described valve body is provided with import valve seat and outlet valve seat, described inlet valve seat is positioned between flashboard and valve body, described import valve seat comprises floating valve seat and spring seat, be provided with spring in described spring seat, described floating valve seat coordinates with extruding between spring seat.
Described spring seat, between floating valve seat and valve body, be also provided with graphite-seal ring.
Be provided with groove bottom described floating valve seat, described spring is positioned at groove.
Described spring seat is provided with boss, and described floating valve seat side is provided with slope, the boss on described spring seat and the slope on floating valve seat and form Seal cage between valve body, and described graphite-seal ring is positioned at Seal cage.
Described valve rod front end is provided with bar head, and described flashboard is provided with connecting groove, and described valve rod is connected with flashboard with connecting groove snap-fit engagement by bar head.
The beneficial effects of the utility model are: the utility model provides a kind of floating valve A seating Wedge gate valve, by making import valve seat into relocatable form, such medium enters from import, promote import floating valve seat, be fitted on flashboard, formation first seals, then medium promotes flashboard again and forms outlet forced seal, this is second sealing, make Gate-valve sealing more reliable by the form of double seal, the design of import floating valve seat can also prevent lumen from boosting, central cavity pressure is abnormal to be raised, when middle cavity pressure is greater than pipeline pressure, middle cavity pressure sternward can back down import floating valve seat, such pressure just can be discharged into inside pipeline.
