Abstract
A butterfly valve provided with a scraper comprises a valve body and a dished end and is suitable for a powder conveying system. A penetrating hollow cavity is arranged inside the dished end from one side of the valve body to the other side of the valve body; a valve shaft is arranged inside the hollow cavity; a rotating shaft is arranged inside the valve shaft; a rotating hand wheel is connected to one end of the rotating shaft at the outer side of the valve body; the center of the rotating shaft is connected with a cleaning shaft by virtue of an axial-radial steering structure inside the hollow cavity, and the scraper is arranged on the outer surface of the dished end at the end part of the cleaning shaft. The powder adhered to the dished end of the butterfly valve can be cleaned without dismounting the butterfly valve, and the blocking and mixing phenomena of the butterfly valve are eliminated.
Description
Technical field:
The utility model relates to a kind of butterfly valve that scraper is installed.
Background technique:
In powder delivery system, (such as the tyre industry conveying black carbon), butterfly valve has certain adhering powder as the switch of control powder, can stick on the butterfly plate of butterfly valve, butterfly valve is stopped up, and the butterfly valve blanking velocity reduces, and affects manufacturing efficiency, when carrying another kind of powder, can with sticked in the past the dish version on powder mixes, generation batch mixing phenomenon affects quality of product.Butterfly valve stops up when serious, needs butterfly valve pulled down to clear up, and is time-consuming.
Summary of the invention:
Deficiency according to dish plate sizing or batch mixing in the prior art, the utility model provides a kind of butterfly valve that scraper is installed, in powder delivery system, in the situation of not pulling down butterfly valve, can clean the powder that falls to stick on the butterfly valve dish version, eliminate obstruction and the batch mixing phenomenon of butterfly valve.
For achieving the above object, technology contents of the present utility model is:
At the dish intralamellar part, along the opposite side from a side of valve body to valve body a cavity that runs through is set.
Valve shaft is installed in cavity, a rotatingshaft is installed in valve shaft.
At the valve body outside, an end connection of rotating handwheel of rotatingshaft; At cavity inside, axially-radially steering structure connection one a cleaning axle is passed through in the center of rotatingshaft.
Described axially-radially steering structure is intermeshing umbrella gear A and umbrella gear B, rotatingshaft is connected with umbrella gear B, axle is cleaned in umbrella gear A connection.
End at the cleaning axle places dish plate outer surface that scraper is installed.
There is a band center hole cavity cap can allow the cleaning axle pass and cavity is sealed.Rotation handwheel by the rotating valve external body drives rotatingshaft, rotatingshaft drives the pair of meshing umbrella gear rotates the cleaning axle, thereby driving scraper rotates centered by the cleaning axle, cleaning falls to stick to the powder of butterfly plate, outside at butterfly valve like this, can control the rotation of the inner scraper of butterfly valve, the powder that is bonded on the butterfly plate is cleaned.
The beneficial effects of the utility model: by cleaning apparatus is installed, can be regularly or effective removing of not timing stick to powder on the butterfly valve dish version, eliminate obstruction and the batch mixing phenomenon of butterfly valve.Improve production efficiency and product quality has also avoided simultaneously butterfly valve to stop up when serious, needs butterfly valve pulled down to clear up phenomenon, saving of work and time.
Description of drawings:
Fig. 1 is the front view of butterfly valve;
Fig. 2 is that the A-A of butterfly valve is to sectional view;
Fig. 3 is I section enlarged view;
Among the figure: 1 for rotating handwheel; 2 is valve shaft; 3 is rotatingshaft; 4 is cavity cap; 5 are the cleaning axle; 6 is scraper; 7 is butterfly plate; 8 is cavity; 9 is umbrella gear A; 10 is umbrella gear B.
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
The utility model comprises valve body and dish plate 7, in dish plate 7 inside, along the opposite side from a side of valve body to valve body a cavity that runs through 8 is set.
Valve shaft 2 is installed in cavity 8, a rotatingshaft 3 is installed in valve shaft 2.
At the valve body outside, an end connection of rotating handwheel 1 of rotatingshaft 3; In cavity 8 inside, axially-radially steering structure connection one a cleaning axle 5 is passed through in the center of rotatingshaft 3; Described axially-radially steering structure is intermeshing umbrella gear A 9 and umbrella gear B 10, and rotatingshaft 3 is connected with umbrella gear B 10, and umbrella gear A 9 connects cleaning axle 5.
End at cleaning axle 5 places dish plate 7 outer surface that scraper 6 is installed, and scraper 6 is centered by cleaning axle 5, and length is the diameter of dish plate 7.
There is the cavity cap 4 with center hole can allow the cleaning axle pass and cavity is sealed.Rotation handwheel 1 by the rotating valve external body drives rotatingshaft 3, rotatingshaft 3 drives the pair of meshing umbrella gear rotates cleaning axle 5, thereby driving scraper 6 rotates, wipe the powder that sticks to butterfly plate off, outside at butterfly valve like this, can control the inner scraper of butterfly valve and rotate, the powder that is bonded on the butterfly plate is wiped off.
