Abstract
The utility model is a kind of novel Wedge type double gate board gate valve, belongs to thermoelectricity, nuclear power valve field.Novel Wedge type double gate board gate valve is made up of valve body, flap, valve seat, valve rod, jack, Universal bearing block, pad etc., and valve rod drives flap to move up and down along valve body guiding groove.Embed jack and Universal bearing block respectively in the groove of flap, be used for automatically adjusting the angle of wedge between two flaps, flap and sealing surface of seat fitted like a glove, ensures the sealing that valve reaches good.By the pad in increase and decrease flap groove, adjust the distance between two valve clack sealing surfaces, effectively avoid two valve clack sealing surface spacings to cross minor valve and occur " lower a heatable brick bed " phenomenon, avoid the excessive valve of two valve clack sealing surface spacings to occur fitting badly phenomenon simultaneously.
Description
Technical field
The utility model relates to a kind of novel Wedge type double gate board gate valve, belongs to thermoelectricity, nuclear power valve field.
Background technique
Wedge type double gate board gate valve is arranged on thermoelectricity, nuclear power generating sets steam-water pipe, is the visual plant cutting off medium.
The Wedge type double gate board gate valve two flap spacing of prior art can not adjust.When sealing surface wear, valve base sealing distance between the surface is greater than valve clack sealing surface spacing, occurs " lower a heatable brick bed " phenomenon, valve function was lost efficacy; In addition, when flap damages and changes, because valve clack sealing surface spacing is non-adjustable, easily produce and fit badly or " lower a heatable brick bed " phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of novel Wedge type double gate board gate valve, makes two flap spacing adjustable.
The technical solution of the utility model is a kind of novel Wedge type double gate board gate valve, and it comprises the position such as the parts such as valve body (1), valve seat (2), flap (3), Universal bearing block (4), jack (5), valve rod (6) and guiding groove (8), T-slot (9), guiding rib (10), groove (11).Valve seat and valve body are welded to connect, and valve body lumen both sides are provided with tape guide groove, and flap both sides are provided with guiding rib, and guiding rib embeds in guiding groove, and valve rod is connected by T-slot with flap, drive flap to move up and down along guiding groove.
Embed jack and Universal bearing block respectively in groove between described novel Wedge type double gate board gate valve two flap, make angle of wedge adjustable between two flaps, flap and sealing surface of seat fit like a glove.
Can increase in the jack of described novel Wedge type double gate board gate valve and Universal bearing block groove or reduce pad, adjusting two valve clack sealing surface spacings, avoiding occurring " lower a heatable brick bed " or fitting badly phenomenon, valve function was lost efficacy.
The beneficial effects of the utility model are: the groove between gate valve two flap is embedded in jack and Universal bearing block, make angle of wedge adjustable between flap, ensure good sealing; Changeable pad in the groove of flap, adjusts two valve clack sealing surface spacings, avoids valve function to lose efficacy.
