Abstract
The utility model discloses a kind of double sealing structure of metallic sealing butterfly valve, comprise lower valve body, upper valve body, working seal gland, work metal o-ring, butterfly plate, maintenance sealing clamp, maintenance sealed piston ring, end cap flange and piston ring position test rod.The utility model has the advantage of that metallic double seals butterfly valve can successfully realize the function that valve one valve replaces many valves, working seal circle can be changed online.In the today that develops water resources rapidly, because water quality is everywhere not quite similar, sealing pair material design is stainless steel, valve can have high temperature resistant, high pressure resistant, wear-resistant, resistance to weak corrosion, the features such as long service life, applied widely, safe and reliable, repair and maintenance convenience, economical and practical, can widely popularize.
Description
Technical field
The utility model relates to a kind of sealing configuration of seal butterfly valve, relates in particular to a kind of double sealing structure of metallic sealing butterfly valve.
Background technique
Current, in the metallic sealing butterfly valve of domestic production, the single sealing configuration of most employing, have inconvenient repair and maintenance for the valve of single sealing configuration in pipe-line system, particularly multi-pipeline unit operating mode, if when a unit occurs that with valve primary seal or shaft sealing go wrong, must just can overhaul by exhausting pipeline, certainly will have influence on so the normal work of other unit and the regular supply of water, and it is longer with the time of water-filling to discharge water, and can have a negative impact to people's production and life.Along with the fast development of national economy and the continuous increase of population, to the demand of water resources and day sharp increase, for promoting regional economy, society coordinate and can hold sexual development, rational utilization of water resources is the matter of fundamental importance that is related to national economy.
Model utility content
The purpose of this utility model is just to provide in order to address the above problem a kind of double sealing structure of metallic sealing butterfly valve.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises lower valve body, upper valve body, working seal gland, work metal o-ring, butterfly plate, maintenance sealing clamp, maintenance sealed piston ring, end cap flange and piston ring position test rod, described upper valve body is installed on described lower valve body, described working seal gland is connected with described butterfly plate by described work metal o-ring, one side of described lower valve body is connected with described working seal gland, the opposite side of described lower valve body is connected with described maintenance sealed piston ring, described maintenance sealing clamp is connected with described butterfly plate, described end cap flange is connected with described maintenance sealed piston ring by described piston ring position test rod.
Further, between described lower valve body, described work metal o-ring and described working seal gland, be provided with O RunddichtringO.
Further, between described lower valve body and described maintenance sealed piston ring, be provided with D RunddichtringO, between described butterfly plate, described lower valve body and described maintenance sealing clamp, be provided with maintenance metal o-ring.
The beneficial effects of the utility model are:
The utility model has the advantage of that metallic double seals butterfly valve can successfully realize the function that valve one valve replaces many valves, working seal circle can be changed online.In the today that develops water resources rapidly, because water quality is everywhere not quite similar, sealing pair material design is stainless steel, valve can have high temperature resistant, high pressure resistant, wear-resistant, resistance to weak corrosion, the features such as long service life, applied widely, safe and reliable, repair and maintenance convenience, economical and practical, can widely popularize.
