Abstract
The utility model discloses a material blocking/discharging rotary valve arc valve core over-position prevention device specialized for an air conveying chute, which is realized through a technical solution: the material blocking/discharging rotary valve arc valve core over-position prevention device is mainly composed of a housing, a backing plate, an over-position preventing block, etc.; the backing plate is welded on the housing; and the over-position preventing block is welded on the backing plate for forming the over-position prevention device. The material blocking/discharging rotary valve arc valve core over-position prevention device specialized for the air conveying chute has the following advantages: reasonable structure; high adaptability; high sealing performance; no material escape, rise, drop or leakage; energy-saving performance; high environment-friendly and economical performance; high practicability; high safety; high reliability; and long service life. The material blocking/discharging rotary valve arc valve core over-position prevention device specialized for the air conveying chute is a set of ideal material blocking/discharging equipment specialized for the air conveying chute.
Description
Technical field
The utility model relates to the conveying of the granular material of industries such as cement, metallurgy, chemical industry, coal, generating, grain; Branch storehouse during the multiple spot blowing is cut and is put etc.; Convenient, flexible, specifically, relate to the special-purpose blowing rotovalve arc spool that cuts of a kind of air conveyer flume and ended device.
Background technology
Original equipment seals badly, and valve was prone to the position, when especially in the storehouse, gaseous tension being arranged, is prone to run, drip, leak, had a strong impact on environment, and the harm staff is healthy, influences result of use and life-span.
The utility model content
The technical matters that the utility model will solve is to overcome the deficiency that prior art exists, and provides a kind of novel air to carry the special-purpose blowing rotovalve arc spool that cuts of skewed slot to end device.
As above design, the technical scheme of the utility model is: the special-purpose blowing rotovalve arc spool that cuts of a kind of air conveyer flume ended device, it is characterized in that, said arc spool ended device by housing, backing plate, ended block and formed; At first welding with backing is connected on the housing, ends block and is welded on the backing plate, forms and ends device.
The special-purpose blowing rotovalve arc spool that cuts of the utility model air conveyer flume ended device, and rational in infrastructure, comformability is strong, good seal; No run, drip, leak, energy-saving and environmental protection, economic, practical; Safety, reliable, the life-span is long, is the desirable special-purpose blowing equipment that cuts of air conveyer flume.
Description of drawings
Fig. 1 is the special-purpose blowing rotovalve structural representation that cuts of air conveyer flume.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The utility model is as shown in the figure, by housing 1, backing plate 2, ended block 3 etc. and form.At first backing plate 2 is welded on the housing 1, ends block 3 and is welded on the backing plate 2, forms and ends device, and good airproof performance, valve were difficult for the position, does not have the material of race phenomenon.
The utility model air conveyer flume is special-purpose to be cut blowing rotovalve arc spool to end device is to be used to control the device that the arc spool is crossed the position, is widely used, good seal, pollution-free, energy-saving and environmental protection, long service life.
Embodiment recited above describes the utility model preferred implementation; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design philosophy; Common engineering staff make the technical scheme of the utility model in this area various distortion and improvement all should belong to the protection domain of the utility model.
