Abstract

The invention relates to an adjustable sealing rotary valve mainly solving the technical problems of short service life, great maintenance and management workloads, poor air tightness, easy occurrence of equipment accidents in case of use under high-temperature working conditions, and the like of a traditional rotary valve. The adjustable sealing rotary valve is characterized by comprising a rotary valve shell and a rotor (3), wherein the rotor (3) is provided with a rotor groove (4), the rotary valve shell is provided with a feeding hole (1) and a discharging hole (5) which are provided with a feeding hole connecting piece (11) and a discharging hole connecting piece (51), a sealing sleeve (6) in a notched circular structure is sleeved in the rotary vale shell (2), a sliding sleeve (8) in movable fit is arranged in the feeding hole (1) at the upper part of the rotary valve shell (2), and the lower part of the sliding sleeve (8) is in arc shape and is sleeved between the sealing sleeve (6) and the rotor (3) in a matching way. The valve body is separated from a container of the rotor by changing a structure mode of directly containing the rotor in the body of the traditional rotary valve so as to emphatically prolong the service life and improve the air tightness of the rotary valve. The invention is mainly applied to a powder or granule conveying device.

Description

technical field [0001] The invention relates to a rotary valve used in a powder or granular material conveying device. Background technique [0002] In the process of conveying powder or granular materials, especially quantitative conveying devices with high air tightness requirements, star-shaped rotary valves are generally required. At present, the structure of the general star rotary valve is as follows figure 1 As shown, it is composed of a multi-slot rotor 3 and the inner hole of the valve housing 21 according to the powder particle size, temperature and other factors to form a sealed discharge structure according to certain tolerance requirements. It is a rotary valve The inner hole of the casing 21, that is, the casing containing part 61 directly contains the structural type of the rotor 3, that is, it is composed of the valve casing 21 and the rotor 3, and the valve casing 21 is provided with a valve that matches the rotor 3. The housing contains a part 61, the rot...
