Abstract
The utility model discloses a dual-valve plate type soft seal butterfly valve, comprising a tubular valve body, an upper half shaft and a lower half shaft respectively are rotatably arranged above, below the valve body, two ends of the valve body respectively are an inlet end and an outlet end, a left valve plate and a right valve plate respectively are fixedly mounted on two sides of a lower end of the upper half shaft, an upper end of the lower half shaft and the lower end of the left valve plate or the right valve plate are arranged rotatably, a pressing sleeve is fixed in the inlet end, a sealing ring body is arranged on top of a front end of the pressing sleeve, the sealing ring body fits edges of the left valve plate and the right valve plate. According to the utility model, the valve is featured with reasonable structures, is easily assembled/disassembled and maintained, and is mounted at any position, therefore, structures are simple and compact, operating torque is small, 90-degree rotation starts fast, flow characteristics are like a straight line, and adjusting performance is good.
Description
Technical field
The utility model relates to the butterfly valve field, specifically belongs to the board-like soft sealing butterfly valve of bivalve.
Background technique
At present, the board-like soft sealing butterfly valve of bivalve obtains using very widely in many fields such as oil, chemical industry, metallurgy, water power as a kind of parts that are used for realizing pipe-line system break-make and flow control.In known butterfly valve technology, its seal form adopts sealing configuration more, and sealing material is rubber, teflon etc.Because the restriction of structure characteristic, incompatibility is high temperature resistant, high pressure and corrosion-resistant, industry such as resistance to wear.
The model utility content
The purpose of the utility model provides the board-like soft sealing butterfly valve of a kind of bivalve, adopts double layer construction reasonable in design, easily dismounting and maintenance; And can install at an arbitrary position, simple in structure, compact, the operation moment of torsion is little; 90 degree revolutions are opened rapidly, the Flow characteristics straight line that becomes, and adjusting function is good.
The technological scheme of the utility model is following:
The board-like soft sealing butterfly valve of bivalve includes the valve body of tubulose, and the top of valve body, below are rotated and be provided with semiaxis, time semiaxis; Said two ends of valve body is respectively entrance point, outlet end; The both sides, lower end of last semiaxis are installed with left valve plate, right valve plate respectively, and the lower end of the upper end of following semiaxis and left valve plate or right valve plate is rotated and is provided with, and the entrance point internal fixation has gland; The front end overhead of gland has the sealing circle body, fits and be provided with in the edge of sealing circle body and left valve plate, right valve plate.
Be provided with stuffing box gland between the valve seat on described upward semiaxis and valve body top, be provided with a plurality of seal rings in the stuffing box gland.
Described sealing circle body both sides are provided with projection, and inwall has the flange that stretches out.
The utlity model has left valve plate, right valve plate, reasonable in design, easily dismounting and maintenance, and can installing at an arbitrary position, simple in structure, compact, the operation moment of torsion is little, and 90 degree revolutions are opened rapidly, the Flow characteristics straight line that becomes, adjusting function is good.
