Abstract
A flange type rubber sealing butterfly valve with a whole steel welded structure comprises the following components: a valve chamber, a valve rod sealing chamber which is connected with the valve chamber, and a valve shaft which is provided in the valve chamber and the valve rod sealing chamber. A valve rod tail plug is provided below the valve chamber. A valve plate is fixed below the valve shaft. The valve plate is provided in the valve chamber. A driving connecting plate is provided above the valve shaft. The driving connecting plate is fixed on the valve rod sealing chamber. A special rubber sealing ring is provided between the driving connecting plate and the valve rod. A rubber sealing layer is provided in the valve chamber. A connecting flange is provided outside the valve chamber. The connecting flange comprises a fixed flange and a movable flange. The valve chamber, the valve rod sealing chamber, the valve rod tail plug, the valve plate, the driving connecting plate and the connecting flange are respectively obtained through welding and are respectively made of stainless steel. The flange type rubber sealing butterfly valve with the whole steel welded structure provided by the utility model is suitable for performing medium switch closure and flow adjustment on the pipeline for the media of water, gas and acid object.
Description
Technical field
The utility model relates to a kind of butterfly valve, especially a kind of flange type rubber seal butterfly valve.
Background technique
The existing reed valve material is foundry goods, and the synthetic kink sealing effect of rubber is bad, and complex structure, operation are dumb, can not be according to suitably processing or prolong of actual conditions.
The model utility content
The utility model provides a kind of simple in structure, good sealing effect, easy to operate flange type rubber seal butterfly valve.
Realize a kind of flange type rubber seal butterfly valve of whole body steel welding structure of a kind of simple in structure, good sealing effect, the whole body welding of the utility model purpose, comprise valve pocket, the valve stem seal chamber that links to each other with described valve pocket and be positioned at valve pocket and the valve shaft in valve stem seal chamber; It is stifled that described valve pocket below is provided with the valve rod tail, fixedly there is valve plate described valve shaft below, described valve plate is positioned at valve pocket, described valve shaft upper fixed has the driving land, described driving land is fixed on the valve stem seal chamber, be provided with rubber seal between described driving land and the valve rod, be provided with rubber sealant in the described valve pocket, described valve pocket outside is provided with adpting flange, described adpting flange comprises a fastening flange and a loose flange, described valve pocket, the valve stem seal chamber, the valve rod tail is stifled, valve plate, drive land, be between the adpting flange and be welded, its material is Stainless Steel Tube.
The beneficial effect of the flange type rubber seal butterfly valve of a kind of whole body steel welding structure of the present utility model is as follows:
The flange type rubber seal butterfly valve of a kind of whole body steel welding structure of the utility model patent is applicable to and does on plumbing, gas, the acid content medium pipeline that the medium switch dams and the Flow-rate adjustment effect.Novel in design, simple in structure, in light weight, open and close rapidly; Little, the laborsaving dexterity of operational torque; The whole body welding can be installed in any position or customization prolongs and can directly be connected with welding manner with pipeline according to actual conditions, and is very convenient; Sealing is replaceable, and sealability reliably reaches the two way sealed zero leakage.
