A New Kind of Rotary Valve

(Patent No. :01921151748.6)

Micro vibrant refractory rotary valve.

It is a kind automatic rotary and air blocked machinery equipment which can be opened and closed according to the weight measurement. It is not only allowed to work at high heat condition to feed but also to block the air.  It is the normal equip which is used in the distributer kiln because of its automatic movement without enforce power. If not designed properly, the material will be blocked and air leakage will be occurred which can lead to the heat consumption highly, influencing the quality and operation terribly.


Nanjing Perfect focuses on the efficiency of the usage and analyzes the flaws it is faced with and specialized in designing and providing with the solution, exploiting a new micro vibrant refractory rotary valve which owns the new patent that is new stable character, easy maintenance and nice appearance.


Combination with below:

1valve body. 2refractory board 3bearing and support 4porthole. 5clump weight. 6sectorial adaptor.7 clean point. 8 inspection door

The advantages:

The models normal used: diameter 630mm, 700mm, 850mm,900mm,1000mm,1100mm,1200mm,1300mm, and customized is acceptable according to the customer’s requirement and drawing.


1, Back cover is fixed by screws which can be dismantled and mounted easily to remove the contamination and maintenance it through the entire board withdrawn.

2, Diameter 159mm gate arranged for cleaning the scrapers and inspection.

3, The inspection door is adopted by graphite board and labyrinth design which can block the air, using the flexible bolt screw to tight that no tools required to maintenance.

4, Refractory board is high quality heat resistant with ZG40Cr25Ni20Si2 material, and the reinforce support layout more properly which strengthen and enlarge the life of usage.


5, Outside bearing is famous brand and initial installed with KLUBER41-1501 high temperature

Grease to guarantee the flexibility and long life.

6. Short torque of the board which makes the frequency higher to drop material while blocking the air properly.

7, Weight measurement is flexible adjustable to balance the torque and materialName
