Abstract
The invention relates to an all-metal bidirectional high-pressure butterfly valve which comprises a valve body, a valve rod, a butterfly plate and a driving device, wherein the upper end of the valve rod is connected with the driving device, and the lower end of the valve rod is fixedly connected with the butterfly plate; a movable valve seat arranged in the valve body is arranged on one side of the butterfly plate; a lifting ring is arranged on the outer side of the movable valve seat and is fixedly connected with the movable valve seat through a screw; a butterfly plate sealing surface is arranged on the butterfly plate; a valve seat sealing surface matched with the butterfly plate sealing surface is arranged on the movable valve seat in a sealing manner; the butterfly plate is fixedly connected with a butterfly plate pressing ring; a movable sealing ring is arranged between the butterfly plate and the butterfly plate pressing ring and is positioned on the butterfly plate sealing surface. The all-metal bidirectional high-pressure butterfly valve is high in sealing performance, has a bidirectional sealing function, cannot be limited by the flowing direction of a medium and can bear high pressure.
Description
Technical field
The present invention relates to all-metal reversible high pressure butterfly valve, be used for realizing the parts of pipe-line system break-make and flow control, in many fields such as oil, chemical industry, metallurgy, water power, be widely used.
Background technique
In known butterfly valve technology, it is rubber, teflon, multi-level composite material etc. that its seal form adopts sealing configuration sealing material more at present.Due to the restriction of structure characteristic, be not suitable with high temperature resistant, high pressure and corrosion-resistant, the industry such as resistance to wear.
The hard sealed valve of industrial High Temperature High Pressure mainly be take gate valve, stop valve as main, and this type of valve major defect is: valve is all upper and lower opening structure, and the weight of valve own is large, and cost is high, and on-the-spot installing space is large.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide nothing friction between a kind of sealing surface, there is two way sealed function, during installation, be not subject to MEDIA FLOW to the all-metal reversible high pressure butterfly valve that limits and can bear high pressure.
The technical solution adopted in the present invention is for this reason: comprise valve body, valve rod, dish plate and drive unit, described valve rod upper end is connected with drive unit, valve rod lower end is fixedly connected with dish plate, in valve body, be provided with movable valve seat and be placed in dish plate one side, movable valve seat outside is provided with suspension ring and is fixedly connected with it by screw, dish plate is provided with dish plate sealing surface, movable valve seat is provided with the sealing surface of seat being sealed and matched with dish plate sealing surface, on dish plate, be fixedly connected with dish plate pressure ring, between dish plate and dish plate pressure ring, be provided with loose gland and be positioned at dish plate sealing surface place.
Between described valve body and movable valve seat, be provided with gasket seal one.
Between described loose gland and dish plate, be provided with gasket seal two.
Advantage of the present invention is: the present invention adopts three eccentric sealed principles, good seal performance, there is two way sealed function, during installation, be not subject to MEDIA FLOW to restriction and can bear high pressure, traditional High Temperature High Pressure gate valve, stop valve and ball valve have been replaced, thereby reduced cost of production, in many fields such as oil, chemical industry, metallurgy, water power, be widely used.
