Abstract

An adjustable sealing rotary valve mainly solves technical problems that the traditional rotary valve has short service life, heavy maintenance management workload, bad gas tightness, and when the rotary valve is used in the high temperature work conditions, equipment accidents easily happen, and the like. The adjustable sealing rotary valve has the technical solution that the rotary valve is formed by the combination of a rotary valve shell and a rotor (3), wherein the rotor (3) is provided with a rotor slot (4); the rotary valve shell is provided with a feeding hole (1) and a discharge hole(5); a feeding hole connecting piece (11) and a discharge hole connecting piece (51) are arranged on the feeding hole (1) and the discharge hole (5); the rotary valve shell (2) is internally sheathedwith a seal housing which is of a non-circular structure; the feeding hole (1) on the upper part of the rotary valve shell (2) is internally provided with a sliding sleeve (8) which is movably matched; the lower part of the sliding sleeve (8) is arc-shaped and sheathed between a sealing housing (6) and the rotor (3) in a matching way; by changing the structural style that the valve body of the traditional rotary valve directly contains the rotor, the valve body and a containing component of the rotor are separated, thus prolonging the service life thereof and increasing the gas tightness. Theadjustable sealing rotary valve is mainly used for powder or granule conveying devices.

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 the quantitative conveying device that requires high air tightness, it generally needs to be equipped with a star-shaped rotary valve. At present, the general star-shaped rotary valve has a structure such as 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 combined into a sealed discharge structure according to certain tolerance requirements. It is a rotary valve The inner hole of the housing 21, that is, the housing containment member 61 directly contains the structure of the rotor 3, that is, the valve housing 21 and the rotor 3 are combined, and the valve housing 21 is provided with a matching rotor 3 The housing containment part 61, the rotor...

Embodiment Construction

[0016] In the following, the present invention will be further described in conjunction with the embodiments as follows:

[0017] As shown in the structure of the present invention figure 2 As shown, it is composed of a rotary valve housing 2, a sealing sleeve 6 and a rotor 3, and a rotor slot 4 is provided on the rotor 3, and a feed port 1 and a discharge port are provided on the valve rotary valve housing 5. The feed port 1 and the discharge port 5 are provided with a feed port connector 11 and a feed port connector 51, a sealing sleeve 6 is sleeved in the rotary valve housing 2, and the sealing sleeve 6 is in a round shape In the structure, a sliding sleeve 8 that is movably fitted is arranged in the feed port 1 on the upper part of the rotary valve housing 2, and the lower part of the sliding sleeve 8 is fitted between the sealing sleeve 6 and the rotor 3 in an arc shape. It is also possible to provide an adjusting bolt 7 matched with the sliding sleeve 8 on the wall of the...
