Abstract
The utility model discloses a non-blocking star-shaped cinder valve relating to the valve filed, especially relating to the cinder valve structure. The non-blocking star-shaped cinder valve comprises a valve body, in which is disposed a main shaft in a penetrating manner. The main shaft in the valve body is connected with an impeller, and two sides of the valve body are respectively provided with an end cover. Each of the end covers comprises a first end cover, a second end cover, and a connecting rib. Two ends of the main shaft are respectively provided with a deep groove ball bearing. The two deep groove ball bearings are respectively correspondingly disposed in the end covers. A sealing member is disposed between each of the first end covers and the main shaft. The side of each of the sealing members facing the corresponding first end cover is provided with a sealing gland, which is disposed on the main shaft in a sleeved manner. The two sides of the main shaft close to the valve body adopt the the asbest rope sealing members and the sealing glands for the sealing, and the deep groove bearings are disposed in the second end covers, which are disposed at a certain distance from the valve, and because the dust in the valve body is completely sealed in the valve by the asbest ropes, and cannot enter the deep groove ball bearings, the main shaft can rotate normally for the cinder discharging.
Description
Technical field
The utility model relates to the field of valve, relates in particular to the structure of unloading valve.
Background technique
The grey process of unloading of star-shaped ash unloading valve is to unload ash by being arranged on the continuous rotation of impeller on main shaft, existing star-shaped ash unloading valve mainly comprises valve body, in valve body, place a main shaft, one end connecting power device of main shaft, on main shaft in valve body, connect impeller, the both sides of valve body arrange respectively end cap, each end cap comprises respectively the first end cap and the second end cap, each first end cap is connected with valve body respectively, each second end cap is separately positioned on each first end cap away from a side of valve body, the first end cap is connected by connecting tendon with the second end cap, on each first end cap inner main axis, deep groove ball bearing is set respectively.The deep groove ball bearing of this structure is directly installed on the valve body both sides of unloading valve, because there being a large amount of dusts in valve body, once dust enters in deep groove ball bearing, the ball roller in bearing can be stuck and cannot rotate, at this moment main shaft just cannot rotate and unload ash, and unloading valve also just cannot work.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide that a kind of bearing can be not stuck without jam star-shaped ash unloading valve.
The purpose of this utility model is achieved in that without jam star-shaped ash unloading valve, comprise valve body, in valve body, place a main shaft, one end connecting power device of main shaft, on main shaft in valve body, connect impeller, the both sides of valve body arrange respectively end cap, each end cap comprises respectively the first end cap and the second end cap, each first end cap is connected with valve body respectively, each second end cap is separately positioned on each first end cap away from a side of valve body, the first end cap is connected by connecting tendon with the second end cap, the two ends of main shaft arrange respectively deep groove ball bearing, two deep groove ball bearings are separately positioned in corresponding the second end cap, between each first end cap and main shaft, Sealing is set respectively, each Sealing arranges respectively sealing gland towards a side of the first end cap, each sealing gland is nested with on main shaft respectively.
Main shaft of the present utility model adopts asbestos rope Sealing to add gland near the both sides of valve body and seals, deep groove ball bearing is installed in the second end cap of valve body certain distance, because the dust in valve body is sealed in completely in valve body and can not enters deep groove ball bearing by asbestos rope, main shaft just can normal rotary unloading ash.
One end external diameter of each sealing gland of the present utility model is large, the other end external diameter is little, and the small end of each sealing gland is equipped with respectively in corresponding the first end cap.By sealing gland, Sealing is stuck in the first end cap.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure, 1 bearing cap, 2 deep groove ball bearings, 3 end caps, 3-1 the first end cap, 3-2 the second end cap, 3-3 connecting tendon, 4 Sealings, 5 sealing glands, 6 valve bodies, 7 impellers, 8 main shafts, 9 power plant.
Embodiment
As shown in Figure 1, for without jam star-shaped ash unloading valve, comprise valve body 6, in valve body 6, place a main shaft 8, one end connecting power device 9 of main shaft 8, connects impeller 7 on the main shaft 8 in valve body 6, and the both sides of valve body 6 arrange respectively end cap 3, in two end caps 3, one of them end cap 3 is bolted bearing cap 1, and another end cap 3 is bolted with the shell of power plant 9.Each end cap 3 comprises respectively the first end cap 3-1 and the second end cap 3-2, each first end cap 3-1 is connected with valve body 6 by bolt respectively, each second end cap 3-2 is separately positioned on each first end cap 3-1 away from a side of valve body 6, the first end cap 3-1 is connected by connecting tendon 3-3 with the second end cap 3-2, on each second end cap 3-2 inner main axis 8, deep groove ball bearing 2 is set respectively.Between each first end cap 3-1 and main shaft 8, asbestos rope Sealing 4 is set respectively, each Sealing 4 arranges respectively sealing gland 5 towards a side of the first end cap 3-2, each sealing gland 5 is nested with respectively on main shaft 8, one end external diameter of each sealing gland 5 is large, the other end external diameter is little, and the small end of each sealing gland 5 is equipped with respectively in corresponding the first end cap 3-1.
Claims (2)
1. without jam star-shaped ash unloading valve, comprise valve body, in valve body, place a main shaft, one end connecting power device of main shaft, on main shaft in valve body, connect impeller, the both sides of valve body arrange respectively end cap, each end cap comprises respectively the first end cap and the second end cap, each first end cap is connected with valve body respectively, each second end cap is separately positioned on each first end cap away from a side of valve body, the first end cap is connected by connecting tendon with the second end cap, the two ends of main shaft arrange respectively deep groove ball bearing, it is characterized in that: two deep groove ball bearings are separately positioned in corresponding the second end cap, between each first end cap and main shaft, Sealing is set respectively, each Sealing arranges respectively sealing gland towards a side of the first end cap, each sealing gland is nested with on main shaft respectively.
