Abstract
The utility model discloses a valve base of a soft sealing butterfly valve, which comprises a barrel-shaped base body fixed on the upper end of a valve body, wherein the outer side wall of the base body is provided with a vertical connection board, the outer side of the connection board is provided with a transversal reinforcing board, the base body is internally provided with an upper half shaft, the upper half shaft is sleeved with a composite bearing and a sealing sleeve, and the lower end surface of the sealing sleeve is propped against on the upper end surface of the composite bearing. The valve base disclosed by the utility model has the advantages that the disassembly and the assembly as well as the maintenance are easy, the installation can be carried at any place, the structure is simple and compact, the operation torque is small, the 90-degree rotary starting is quick, the flowing characteristic tends to be linear, and the adjustment property is good.
Description
Technical field
The utility model relates to the butterfly valve field, specifically belongs to the valve seat of soft sealing butterfly valve.
Background technique
At present, 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 valve seat of soft sealing butterfly valve, 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 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 valve seat of soft sealing butterfly valve; Include the pedestal that is fixed in valve body upper end tubular; Said pedestal outer side wall is provided with vertical connecting plate, and the outside of connecting plate is provided with horizontal stiffened panel, is provided with semiaxis in the pedestal; Be set with composite bearing, stuffing box gland on the last semiaxis, the lower end surface overhead of stuffing box gland is on the upper-end surface of composite bearing.
Be provided with the O RunddichtringO in the described stuffing box gland.
Described sealing circle body both sides are provided with projection, and inwall has the flange that stretches out.
The reasonable in design of the 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.
