Abstract
The utility model discloses a soft sealing type butterfly valve which comprises a tubular valve body, wherein an upper half shaft and a lower half shaft are arranged above the valve body and below the valve body in a rotating mode. Two ends of the valve body are respectively an inlet end and an outlet end. A valve seat is arranged on the top of the valve body and is provided with a sealing sleeve. The upper end of the upper half shaft extends into the valve seat and is abutted against the sealing sleeve of the valve seat. A valve plate is fixedly arranged at the lower end of the upper half shaft. A connection block is welded on the lateral wall of the lower end of the valve plate and is provided with a threaded hole. The upper end of the lower half shaft is in threaded connection with the threaded hole of the connection block. A pressing sleeve is fixedly arranged inside the inlet end, and the front end of the pressing sleeve is attached to the rim of the valve plate. The soft sealing type butterfly valve is reasonable in structural design, easy to disassemble, assemble and maintain, capable of being assembled anywhere, simple and compact in structure, small in operation torsion, capable of being fast opened by 90 degrees in rotating mode and ensuring that flow characteristics tend to be a straight line, and good in adjustment performance.
Description
Technical field
The utility model relates to the butterfly valve field, specifically belongs to a kind of flexible sealing type butterfly valve.
Background technique
At present, a kind of flexible sealing type 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.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 model utility content
The purpose of this utility model is to provide a kind of flexible sealing type butterfly valve, 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 technical solution of the utility model is as follows:
a kind of flexible sealing type butterfly valve, include the valve body of tubulose, the top of valve body, the below is rotated and is provided with semiaxis, lower semiaxis, it is characterized in that: the two ends of described valve body are respectively entrance point, outlet end, the top of valve body is provided with valve seat, be provided with stuffing box gland in valve seat, the upper end of upper semiaxis is stretched into valve seat and is against on the stuffing box gland of valve seat, the lower end of upper semiaxis is installed with valve plate, be welded with a contiguous block on the lower end sidewall of valve plate, contiguous block is provided with tapped hole, the upper end of lower semiaxis and the tapped hole of contiguous block screw togather, be fixed with gland in entrance point, fit in the front end of gland and the edge of valve plate.
Described a kind of flexible sealing type butterfly valve is characterized in that: be provided with a plurality of seal rings in described stuffing box gland.
The utility model has the advantages that:
Reasonable in design of the present utility model, 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.
