Abstract
The utility model discloses a steady flow dual-valve plate flexible sealing butterfly valve, which comprises a tubular valve body, an upper half shaft and a lower half shaft are rotatably arranged at the upper and lower parts of the valve body; a left valve plate and right valve plate are fixedly mounted on the two sides of the lower end of the upper half shaft respectively; the upper end of the lower half shaft is rotatably arranged with the lower end of the left valve plate or the right valve plate; pressing sleeves are fixed in an outlet end; gasket ring bodies are propped against the front ends of the pressing sleeves; the gasket ring bodies fit the edges of the left valve plate and the right valve plate; the upper half and the lower half shafts are respectively sleeved with torsional springs; one ends of the torsinal springs are fixed on the upper half and lower half shafts, and the other ends of the torsinal springs are fixed in the valve body; the outlet end of the valve body is fixedly matched with a flow-stabilizing plate; a plurality of water holes are formed on the flow-stabilizing plate; and water stoppers are flexibly connected with the water holes. The valve disclosed by the utility model is reasonable in structural design, easy to dismount and maintain, simple and impact in structure and small in operation torsional moment, can be mounted at any positions and is quick in 90-degree gyration start, and meanwhile, owing to an effect of the torsional springs, the valve plates can automatically return initial positions, a flow characteristic is stable, and regulation performance is favorable.
Description
Technical field
The utility model relates to the butterfly valve field, specifically belongs to stable flow type bivalve plate soft sealing butterfly valve.
Background technique
At present, stable flow type bivalve plate soft sealing butterfly valve 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 a kind of stable flow type bivalve plate soft sealing butterfly valve, 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; Owing to the effect of torsion spring, valve plate can be got back to initial position automatically simultaneously, and adjusting function is good.
The technological scheme of the utility model is following:
Stable flow type bivalve plate soft sealing butterfly valve 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, and 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; The entrance point internal fixation has gland, and 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 respectively installed with torsion spring on last semiaxis, the following semiaxis; One end of torsion spring is fixed on semiaxis, the following semiaxis, and the other end is fixed in the valve body, and the outlet end secure fit of valve body has stabilier; Have a plurality of water passage holes on the stabilier, flexibly connected the water blockoff plug on the water passage hole.
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.
The utlity model has left valve plate, right valve plate, reasonable in design, dismounting and maintenance easily; And can install at an arbitrary position, simple in structure, compact, the operation moment of torsion is little; 90 spend revolution opens rapidly, and owing to the effect of torsion spring, valve plate can be got back to initial position automatically simultaneously; The Flow characteristics straight line that becomes, adjusting function is good.
