Abstract
The utility model discloses a self pressure-relieving type double valve plate soft seal butterfly valve, which comprises a tubular valve body, wherein an upper half shaft and a lower half shaft are rotatably arranged above and below the valve body, the two ends of the valve body are respectively provided with an inlet end and an outlet end, the two sides of the lower end of the upper half shaft are respectively fixedly provided with a left valve plate and a right valve plate, the upper end of the lower half shaft and the lower end of the left valve or the right valve plate are rotatably arranged, a pressing sleeve is fixed in the inlet end, a sealing ring body is supported on the front end of the pressing sleeve, the sealing ring body and the edges of the left valve plate and the right valve plate are arranged by fitting, the upper half shaft and the lower half shaft are respectively provided with torsion springs, one end of the torsion springs is fixed on the upper half shaft and the lower half shaft, the other ends of the torsion springs are fixed in the valve body, a connecting body is connected between the left valve plate and the right valve plate, and a water channel is opened in the connecting body. The water channel comprises a cone hole section, wherein a sealing ball is arranged in the cone hole section, and the outer side of the sealing ball is pressed with a setup spring. The self pressure-relieving type double valve plate soft seal butterfly valve is reasonable in structure design and easy to be dismantle and maintain, can be arranged on any positions, is simple and compact in structure, small in operating torque, rapid to open in 90 degrees in a revolution mode, and discharges too high water pressure by utilizing a one-way valve, thereby preventing service life of a butterfly valve from being affected by the too high water pressure.
Description
Technical field
The utility model relates to the butterfly valve field, specifically belongs to from pressure-relief type bivalve plate soft sealing butterfly valve.
Background technique
At present,, in many fields such as oil, chemical industry, metallurgy, water power, obtain using very widely as a kind of parts that are used for realizing pipe-line system break-make and flow control from pressure-relief type bivalve plate soft sealing butterfly valve.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
