Abstract
The utility model provides an air-cooled type high temperature liner regulating butterfly valve. The regulating butterfly valve comprises a valve body provided with a valve body external sleeve and a valve body internal sleeve, wherein, a valve body upper bracket and a valve body lower bracket are respectively arranged at the upper and the lower parts of the valve body, a sealing strip is arranged on the inner side surface of the valve body, a valve plate is arranged in the valve body and is driven to rotate by the rotation of a rotating shaft, a liner is arranged between the valve body external sleeve and the valve body internal sleeve, and the sealing strip is arranged on the inner cavity of the valve body; a bearing is arranged at the outer parts of the upper bracket and the lower bracket. The utility model has the advantages that the volume is small, the structure is simple, the weight is as light as a quarter of the original product, the service life is long, and both the installation and the maintenance are convenient, thereby being an energy saving and environmental protection product. The product adopts a form that the bearing is externally arranged, thus the axle hanging phenomenon at high temperature is avoided, and the torque is reduced; the air-cooled type is adopted, thus the temperature of the valve cavity is assuredly reduced, the intensity of the valve plate and the rotating shaft is effectively improved, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of adjusting butterfly valve, and particularly a kind of air-cooled high temperature lining is regulated butterfly valve.
Background technique
It is in the sulphur fume pipe that the high temperature lining is regulated butterfly valve, and as the special-purpose butterfly valve of adjutage channel temp, 1200 ℃ of maximum temperatures contain S in the flue gas
2O
3, SO
2, Yin Gaowen manual operation difficulty adopts the pneumatic or electronic angle (0 ~ 90 °) of controlling unlatching automatically sometimes, is closed condition when the angle of opening is 0 °, opens fully when the angle of unlatching is 90 °.This product is the key equipment in the acid production with sulphur project, and this product also is used widely in the chemical metallurgy industry.
Present production status: this valve adopts water-cooled form at present, reduces the temperature of valve plate in hot environment, makes it indeformable, but volume is big, weight is big, moment of torsion is big, have shortcomings such as inconvenience maintenance, and working life is short, cause the expense material, take the energy, inconvenience is installed.For this reason, this product is at chemical industry, and industries such as metallurgy have caused the difficult problem of general character, and the industry that has can only be selected from external import this type of valve.According to the demand in market, through nearly 3 years Field Research, and absorbed external advanced design, in conjunction with the field requirement of China's acid production with sulphur, the high temperature lining of being badly in need of a kind of natural wind cooling structure is regulated butterfly valve.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of air-cooled high temperature lining and regulates butterfly valve, is beneficial to the needs in market, with the product replacement old product of saving metal material and energy environmental protection.
For achieving the above object, technical solution of the present utility model provides a kind of air-cooled high temperature lining and regulates butterfly valve, the structure of this adjusting butterfly valve comprises the valve body that is provided with cover in valve body overcoat and the valve body, the top and the bottom of valve body are provided with valve body upper bracket and valve body lower support frame respectively, and the valve body inner side surface is provided with sealing strip, are provided with valve plate in the valve body, rotation by rotating shaft, the rotation of drive valve plate, wherein: be provided with lining between the cover in described valve body overcoat and valve body, described sealing strip is located at the both sides of valve plate; On the outside of described lower support frame, be provided with bearing.
Described valve plate and rotating shaft interconnect, and are hollow-core construction, form the passage of air ventilation up and down.
Effect of the present utility model is that the adjusting butterfly valve volume of this structure is little, simple in structure, in light weight, is 1/4 weight of original product, long service life, and be easy for installation and maintenance, be a kind of product of energy-conserving and environment-protective.This product adopts the external form of bearing in design, prevents the phenomenon of seize at high temperature, has reduced moment of torsion, adopts air-cooledly, reduces the temperature of valve pocket naturally, has improved the intensity of valve plate and rotating shaft effectively, and is easy to use.
