Beschreibung
Zusammenfassung:	The utility model relates to an ultra -low temperature plate valve, including valve body, disk seat, flashboard, valve rod, valve gap, mainly that sealed face of flashboard outlet side and the dual plane of outlet side disk seat constitution soft or hard are sealed vice, it is vice that sealed of flashboard intake side and intake side disk seat constitute the wedge -type seal. Having the elasticity compensation structure characteristics of wedge gate valve promptly, having the soft or hard double sealing of plate valve, the characteristics of self -cleaning sealed face structure again, have the micro -strain of the super low temperature working condition flashboard of automatic compensation, its sealing performance is reliable. Be applicable to the ultra -low temperature medium operating mode of trades such as oil, chemical industry.
