Abstract

The utility model belongs to the technical field of rotary valves, in particular to a rotary valve shell. An inlet of the rotary valve shell is arranged along the tangent direction of the rotation track of a rotor in the shell. As the inlet of the shell is arranged along the tangent direction of the rotation track of the rotor in the shell, material can enter the inner portion of the shell along the tangent direction of the rotation track of the rotor, thereby greatly reducing the shearing force between the rotor and the material when a rotary valve operates, reducing the fault rate of the rotary valve, having excellent one-off control to the material, and greatly prolonging the service life of the rotary valve.

Description

The rotovalve housing

Technical field

The utility model belongs to the rotovalve technical field, is specifically related to a kind of rotovalve housing.

Background technology

Rotovalve at present commonly used mainly is made of cast iron or aluminium shell and the axle that has the Flow of Goods and Materials passage that is sealed in the shell, usually the top of shell is provided with inlet point, the bottom is provided with discharging opening, under the effect of driver train axle is rotated in certain angle to realize the break-make control of material.The rotovalve of this structure is stuck by material easily when carrying the bigger solid material of hardness, fault rate is higher, especially when being full of solid material in the valve body, the unlatching of valve, close closed procedure and make each faying face serious wear in the valve body, greatly reduce the service life of rotovalve.

Summary of the invention

The purpose of this utility model provides a kind of rotovalve housing, its simple structure, and controlled good to the break-make of material.

For achieving the above object, the utility model has adopted following technical scheme: the tangential direction setting of the rotary motion trace of a kind of rotovalve housing, the inlet of the housing rotor in the housing.

As shown from the above technical solution, the inlet of the utility model housing is set to the tangential direction setting of the rotary motion trace of the rotor in the housing, thereby make material also enter enclosure interior along the tangential direction of the rotary motion trace of rotor, shearing force when greatly reducing the rotovalve operation thus between rotor and the material, reduced the fault rate of rotovalve, controlled good to the break-make of material, and prolonged service life of rotovalve greatly.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the local structure scheme drawing that axially dissects along axle of Fig. 1.

The specific embodiment

Referring to as shown in Figure 1, a kind of rotovalve housing, the inlet 11 of housing 10 is along the tangential direction setting of the rotary motion trace of housing 10 internal rotors 20.

As preferred version of the present utility model, the outlet 12 of housing 10 is also along the tangential direction setting of the rotary motion trace of housing 10 internal rotors 20, can make material be transported in the next workflow and go from exporting 12 places faster thus, also further reduce simultaneously the shearing force between material and the rotor, reduced rotovalve in-to-in degree of wear.

Further, as shown in Figure 1, described inlet 11 be set to depart from rotor 20 directly over, also promptly enter the mouth 11 and rotor 20 between line and pass between the vertical curve of rotor 20 at angle, when can preventing the rotor rotation, this setup cuts and clamps material, thereby further reduced the fault rate of rotovalve, prolonged the service life of rotovalve.

The transverse shape of described inlet 11 and outlet 12 is square, helps the quick conveying of material.

The both sides of described housing 10 are respectively arranged with end cap 13, and the two ends of the rotating shaft 21 of described rotor 20 are separately fixed on the end covers at two sides 13.

The two ends of described rotating shaft 21 are provided with wearing-proof bearing 30, and wearing-proof bearing 30 is fixed on the end cap 13.

The both ends of rotating shaft 21 all are supported on the wearing-proof bearing 30, stressed evenly, compact conformation helps the stable rotation of rotor 20, also helps the smooth operation of rotovalve simultaneously.The setting of wearing-proof bearing 30 can further reduce the fault rate of rotovalve, prolongs the service life of rotovalve.
