Description

Technical Field

[0001] The utility model relates to the technical field of powdery dye production and discharging equipment, in particular to a powdery dye production and discharging plate valve. Background Art

[0002] Powdered dyes can be processed into fine powder, ultrafine powder and dust-free powder to meet different application needs; powdered dyes are generally transported by pipelines. During the pipeline transportation process, a gate valve is required to control the flow and closing of the pipeline. The principle is that a circular opening of the same diameter is opened on the gate plate. The gate plate is opened and closed to make the circular opening on the gate plate completely separate and match the diameter to meet the transportation needs of powdered dyes.

[0003] A manual switch valve structure for gas delivery of powdered materials (CN213145412U), including a valve body, a core shaft movably connected to the valve body through a bracket, the core shaft can be rotated to move along its own axial direction, one end of the core shaft is connected to the valve plate, and the other end is connected to the hand wheel, the hand wheel is turned to drive the core shaft to rotate the valve plate to move horizontally, open or close the passage in the valve body, and the valve body is also provided with a sealing device and an inflation component. The manual switch valve structure for gas delivery of powdered materials adds a sealing device on the basis of the traditional plate valve switch valve to improve the sealing performance of the valve plate. However, in use, since a circular opening of the same diameter needs to be opened on the gate plate, when the gate plate rises, the circular opening is in a flow state, which may cause the powdered dye to overflow, requiring the user to collect the powdered dye later, causing trouble to the user.

[0004] For this purpose, we propose a discharge plate valve for powder dye production. Utility Model Content

[0005] The utility model aims to provide a discharge plate valve for powdered dye production to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a powder dye production discharge plate valve, comprising a valve body, a screw transmission structure and an airbag sealing ring, flanges connected to a powder dye delivery pipeline are fixed at both ends of the outer wall of the valve body, a side bracket is mounted on the upper end of the reinforcing rib, and a screw transmission structure for delivering power is mounted in the middle of the upper end of the side bracket, a slide rail is welded to the inner wall of the middle part of the side bracket, and a valve core is slidably connected to the inner wall of the slide rail, the valve core is embedded in a semicircular groove, and airbag sealing rings are attached to both sides of the inner wall of the semicircular groove, the air inlet end of the airbag sealing ring is connected to a two-way pipe, and the parallel connection of the two-way pipes is connected to an air pump connecting pipeline.

[0007] Preferably, a screw transmission structure is fastened with a bolt in the middle of the upper end of the valve core, and the screw transmission structure pulls the valve core to lift and lower.

[0008] Preferably, the end of the gas pump connecting pipeline is connected to the gas pump.

[0009] Preferably, a semicircular groove is provided in the middle of the valve body, and reinforcing ribs are welded in the middle of both sides of the outer wall of the valve body.

[0010] Preferably, a groove is provided in the middle of the inner side of the airbag sealing ring, and the airbag sealing ring is attached to the surface of the valve core.

[0011] Preferably, the airbag sealing ring is distributed in a semicircular shape, and the sizes of the airbag sealing ring and the semicircular groove match each other.

[0012] Preferably, the airbag sealing rings on both sides are inflated to seal and protect the semicircular groove, and the airbag sealing ring and the groove form a double-layer sealing structure.

[0013] Compared with the prior art, the beneficial effect of the utility model is that when the powdered dye production discharge plate valve is used, the screw transmission structure serves as a power source, and drives the screw to rotate through manual or motor transmission, thereby pulling the valve core to gradually rise and fall, so as to satisfy the user's control of the opening and closing of the valve body, making it convenient for the user to use.

[0014] The air pump connecting pipe serves as the air intake pipe of the airbag sealing ring. The gas is delivered to the airbag sealing ring through pump pressure. The valve core and the valve body are sealed by expanding the airbag sealing ring to meet the sealing requirements of the valve body and ensure that the valve body can effectively transport powdered dyes. The airbag sealing ring plays a good sealing and protective role.

[0015] The cross-section of the airbag sealing ring is an M-shaped structure. By opening a groove in the airbag sealing ring, the airbag sealing ring fits tightly against the valve core, thereby providing a good double-layer sealing protection. At the same time, when the airbag sealing ring expands, its volume increases, and the airbag sealing rings on both sides are squeezed together to block the semicircular groove, thereby further improving the sealing strength of the valve body and meeting the needs of the valve body for long-term transportation of powdered dyes.

The airbag sealing ring 5 plays a good sealing and protective role. A semicircular groove 12 is opened in the middle of the valve body 1, and reinforcing ribs 11 are welded in the middle of both sides of the outer wall of the valve body 1. A groove 53 is opened in the middle of the inner side of the airbag sealing ring 5, and the airbag sealing ring 5 is attached to the surface of the valve core 32, the airbag sealing ring 5 is distributed in a semicircular shape, and the sizes of the airbag sealing ring 5 and the semicircular groove 12 match each other.
