Abstract
The utility model relates to an all-metal both-way high-pressure butterfly valve. The all-metal both-way high-pressure butterfly valve comprises a valve body, a valve rod, a dish plate and a drive device. The upper end of the valve rod is connected with the drive device, and the lower end of the valve rod is fixedly connected with the dish plate. A movable valve seat arranged inside the valve body is placed on one side of the dish plate, and the outer side of the movable valve seat is provided with a flying ring which is fixedly connected with the movable valve seat through a bolt. A dish plate sealing surface is arranged on the dish plate, the movable valve seat is provided with a valve seat sealing surface which is matched with the dish plate sealing surface in a sealed mode, a dish plate pressing ring is fixedly connected to the dish plate, and a movable sealing ring arranged between the dish plate and the dish plate pressing ring is located at the dish plate sealing surface. The all-metal both-way high-pressure butterfly valve is good in sealing performance, has the function of both-way sealing, is not limited by the flow direction of a medium in the process of installing and is capable of bearing high pressure.
Description
Technical field
The utility model relates to the all-metal reversible high pressure butterfly valve, is 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, is widely used.
Background technique
In known butterfly valve technology, it is rubber, teflon, multi-level composite material etc. that its seal form adopts the 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.
The model utility content
For above-mentioned defect, the purpose of this utility model is to provide nothing friction between a kind of sealing surface, has the two way sealed function, during installation, is not subject to MEDIA FLOW to the all-metal reversible high pressure butterfly valve that limits and can bear high pressure.
The technological scheme that the utility model adopts for this reason is: comprise valve body, valve rod, dish plate and drive unit, described valve rod upper end is connected with drive unit, the valve rod lower end is fixedly connected with the dish plate, be provided with movable valve seat in valve body and be placed in dish plate one side, the movable valve seat outside is provided with suspension ring and is fixedly connected with it by screw, the dish plate is provided with dish plate sealing surface, movable valve seat is provided with the sealing surface of seat be sealed and matched with dish plate sealing surface, be fixedly connected with dish plate pressure ring on the dish plate, be provided with loose gland between dish plate and dish plate pressure ring and be positioned at dish plate sealing surface place.
Be provided with gasket seal one between described valve body and movable valve seat.
Be provided with gasket seal two between described loose gland and dish plate.
The utility model has the advantages that: the utility model adopts three eccentric sealed principles, good seal performance, there is the 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, be widely used in many fields such as oil, chemical industry, metallurgy, water power.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view of A in Fig. 1.
Fig. 3 is three eccentric center principle figure of the present utility model.
In figure, 1 is valve body, the 2nd, valve rod, the 3rd, dish plate, the 4th, drive unit, the 5th, movable valve seat, the 6th, suspension ring, the 7th, screw, the 8th, dish plate pressure ring, the 9th, loose gland, the 10th, gasket seal the, the 11st, gasket seal two.
