Problems solved by technology

[0002] At present, gas is mostly used as the carrier for dry powder and granular materials, and the conveying speed of the material is changed by adjusting the gas flow velocity. However, the traditional devices for adjusting the gas flow velocity are relatively complicated, and it is realized by setting up an electrical interlocking device. Cost High, high failure rate, fine adjustment cannot be achieved, and maintenance is complicated

Embodiment 1

[0013] This embodiment provides an air-supplement regulating valve for conveying powdery materials. The regulating valve includes a valve body 2, which is used to connect a sleeve 3 and a material output pipe 4. The sleeve is composed of an inner tube and an outer tube. Composition, the inner pipe is a material input pipe, and the first conveying air channel is formed between the inner pipe and the outer pipe.

[0014] A material hole 24 is provided on the end surface of the valve body corresponding to the material input pipe, and it can be seen that the material hole and the material input pipe are connected. The end surface of the valve body corresponding to the material output pipe is provided with a powder-air mixing chamber 25, and it can be seen that the powder-gas mixing chamber is connected to the material output pipe. The material hole communicates with the powder-air mixing chamber, and it can be seen that the material enters the material hole of the valve body from ...

Embodiment 2

[0019] This embodiment is further improved on the basis of embodiment 1:

[0020] The airflow regulator includes a first bolt 11 and a second bolt 12 sleeved on the first bolt, the stud 112 of the first bolt is connected with a conical head 113, and the second bolt 12 is clamped on the first bolt 12. Between the conical head 113 of the bolt and the bolt head 111, the vent hole 13 is provided on the conical head 113, and the second bolt is threadedly connected with the installation channel.

[0021] Since the second bolt is clamped between the conical head and the bolt head of the first bolt, the first bolt cannot be pulled out from the second bolt. When it is necessary to adjust the angle of the ventilation hole, usually the first bolt cannot be turned directly, because in order to ensure the sealing, the conical head of the first bolt and the installation channel are generally an interference seal. Cause damage to the contact surface and affect the seal. Since the second bo...

Embodiment 3

[0024] This embodiment is further improved on the basis of above-mentioned embodiment 2:

[0025] The installation channel is composed of a through hole 21 and a blind hole 22 arranged on both sides of the central axis of the second delivery air channel. The shape of the blind hole matches the shape of the conical head on the first bolt, and the through hole communicates with the second Two conveying air passages and the outer wall of the valve body, the through hole 21 is threadedly connected with the second bolt 12 .

[0026] This embodiment provides an installation channel for the airflow regulator in Embodiment 2. The installation channel of this structure is composed of a through hole and a blind hole, and the blind hole further improves the airtight performance.

Abstract

The invention discloses and mainly aims to provide an air make-up adjusting valve for powdery material conveying, which is simple in structure and can realize fine adjustment. The air make-up adjusting valve comprises a valve body and airflow regulators, wherein a material hole, second conveying air passages and a powder and air mixing bin are formed in the valve body; the material hole and the second conveying air passages are communicated with the powder and air mixing bin respectively; a mounting channel is arranged on the valve body and crossed and communicated with the corresponding second conveying air passage; a venthole is formed in the part, in the second conveying air passages, of each airflow regulator; the included angle between the axis of each venthole and the axis of the corresponding second conveying air passage can be changed to adjust the opening degree of the corresponding second conveying air passage. As only the valve body and the airflow regulators working together with the valve body are provided, the structure is very simple; as the ventholes are formed in the airflow regulators in the second conveying air passages, the included angles between the axes of the ventholes and the axes of the second conveying air passages can be adjusted to realize fine air adjustment.

Description

technical field [0001] The invention relates to an air supplement regulating valve for conveying powder materials. Background technique [0002] At present, gas is mostly used as the carrier for dry powder and granular materials, and the conveying speed of the material is changed by adjusting the gas flow velocity. However, the traditional devices for adjusting the gas flow velocity are relatively complicated, and it is realized by setting up an electrical interlocking device. Cost It is expensive, has a high failure rate, cannot achieve fine adjustment, and is complicated to maintain. Contents of the invention [0003] In view of the above-mentioned problems, the present invention provides a powder material conveying air supplement regulating valve with simple structure and capable of fine adjustment. [0004] In order to achieve the above-mentioned purpose, the air supplement regulating valve for powder material conveying of the present invention includes a valve body u...
