Embodiment Construction

[0039] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0040] The invention discloses a rotary sealing valve, which is a valve used for feeding materials, mainly transporting solid granular objects or powdery objects, and mainly used in the field of metallurgy and coking. The following are specific examples:

[0041] The main improvement of the rotary sealing valve of the present invention lies in the improvement of its driving mode, sealing and easy-wearing parts. The rotary sealing valve includes a valve body 1 and a rotor 2 arranged in the valve body 1 for feeding materials. The rotor 2 feeds materials through continuous rotation, and the valve body 1 corresponding to the upper end and the lower end of the rotor 2 is provided with a material inlet 16 and a material outlet 17 . The rotor 2 is provided with several feed bins for charging, and the rotation of the rotor 2 is driven by a driving dev...

Abstract

The invention relates to a rotary sealing valve, and belongs to the technical field of sealing valves. The rotary sealing valve comprises a valve body and a rotor arranged inside the valve body and matched with the inner wall of the valve body; a rotating supporting device having supporting and sealing effects is arranged at each of two ends of the rotor; one rotating supporting device is in powerconnection with a driving device; each rotating supporting device comprises an outer supporting ring fixed inside the valve body and an inner rotating gear ring arranged inside the outer supporting ring and driven by the driving device to rotate; and the outer diameter of each inner rotating gear ring and the outer diameter of the rotor are arranged in a correspondingly connected manner. The rotating supporting devices are arranged inside the rotary sealing valve and are driven by the driving device from the edges of the rotating supporting devices, and the rotating supporting devices have the supporting transmission and sealing effects. The rotating supporting devices are stable in transmission and good in sealing effect through cooperation with sealing rings. Thermal spraying of hard alloys is performed on easy-to-wear parts of the rotary sealing valve, so that the wear resistance is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a rotary sealing valve, which belongs to the technical field of sealing valves. Background technique [0002] Rotary sealing valve is also called rotary valve, or star-shaped ash unloading valve. Its function is uniform feeding, uniform receiving and sealing, and it is widely used in our country. The rotary sealing valve has a valve body and a rotor arranged in the valve body. The upper end of the valve body is provided with a feed port and the lower end is provided with a discharge port; the rotor has a central main shaft and blades, and the central main shaft and blades of the rotor form a material receiving cavity. During the working process, the rotor is in a state of continuous rotation for receiving and discharging materials. The rotary valve in the prior art adopts the design idea of ​​Kubota Company of Japan, and usually the rotation of the central main shaft is linked with the rotor. The rotor blades carry materials i...
