Detailed Description

The pneumatic material cleaning switching valve comprises a valve body 1, a valve core 2, a control cylinder 3 and a connector 4 (see the attached figures 1 and 2 in the specification).

The valve body 1 comprises a mounting bracket 10, a valve cylinder 11 and a supporting roller 14 (see the description and the attached figure 6).

The valve cylinder 11 is arranged on the assembly frame 10; the outer surface of the upper end of the valve cylinder 11 is symmetrically provided with through holes 12; sealing plates 13 (see the description and the attached figure 6) are arranged on the assembly brackets 10 at the two sides of the upper end of the through hole 12; the valve core 2 is slidably mounted on the mounting bracket 10 below the sealing plate 13 (see the description and the attached figure 1). The sealing plate 13 is connected with the upper surface of the valve core 2 in a sliding and sealing way.

A plurality of supporting rollers 14 are symmetrically arranged on the assembly frame 10 and the valve barrel 11 at two sides below the valve core 2 (see the attached figures 1 and 6 in the specification); the valve element 2 is connected to the support roller 14. The supporting rollers 14 are provided for the purpose of: so that in operation, the support rollers 14 provide rolling support for the valve cartridge 2, thereby reducing the risk of "jamming" of the valve cartridge 2.

The valve core 2 comprises a bottom plate 5, a material guiding cylinder 6 and a material cleaning plate 8 (see the attached figures 4 and 5 in the specification). The bottom plate 5 is in rolling connection with a supporting roller 14 on the valve body 1; a material guide cylinder 6 is arranged above one end of the bottom plate 5; a material leaking hole 7 is arranged on the bottom plate 5 below the material guide cylinder 6 (see the attached figures 4 and 5 in the specification).

A material cleaning plate 8 is obliquely arranged between the upper end of one side of the material guide cylinder 6 and the end socket of one end of the bottom plate 5; the other side of the guide cylinder 6 is provided with a connecting rib plate 9; the connecting rib plate 9 is connected with a piston rod of the control cylinder 3 through the connector 4. When the control cylinder 3 works, the valve core 2 can be driven by the connector 4 to slide back and forth in the valve body 1.

The control cylinder 3 is arranged on the assembly frame 10 on one side of the valve cylinder 11; the control cylinder 3 is connected with one end of the valve core 2 through a connecting head 4 (see the attached figures 1 and 7 of the specification). The connector 4 comprises a bolt 17, a limiting clamp spring 18 and a connecting fork 16; a connecting fork 16 is connected to the end of the piston rod of the control cylinder 3 through threads; one end of the connecting rib plate 9 is positioned inside the connecting fork 16; the connecting fork 16 is connected with the connecting rib plate 9 through a bolt 17; and the bolt 17 above and below the connecting fork 16 is provided with a limiting clamp spring 18 (see the attached figure 7 in the specification). When the control cylinder 3 works, the valve core can be driven to move back and forth by the connector 4.

The valve cylinder 11 above the valve core 2 is provided with a guide cone cylinder 15 (see the description and the attached figure 6). The purpose of the guide cone 15 is to: so that the material can smoothly enter the switching valve under the guidance of the guide cone 15 during operation.

When the pneumatic material cleaning switching valve is in an open state, the material leakage hole 7 of the valve core 2 corresponds to the valve cylinder 11 of the valve body 1 (see the attached figure 1 of the specification); when the valve core 2 works in such a way, materials can enter the material guide cylinder 6 of the valve core 2 under the guidance of the guide cone cylinder 15, sequentially pass through the material leakage hole 7 and the valve cylinder 11, and enter a designated position.

When a material is conveyed and stops feeding, the control cylinder 3 drives the valve core 2 to move to a closed state through the connector 4. The material cleaning plate 8 of the valve core 2 corresponds to the guide cone cylinder 15 (see the description and the attached figure 2); if the switching valve is in a closed state, when a small amount of materials which have stopped feeding fall into the switching valve, the fallen materials are finally discharged along the through hole 12 along the inclined surface of the material cleaning plate 8 under the action of gravity. So can avoid the material that drops to pile up the problem on case 2 upper portion. Then when another material needs to be fed, the switching valve is opened to normally operate.

The pneumatic material cleaning switching valve has compact structure and smart design; when it is in the closed condition, the material that scatters will directly be arranged outward along the inclined plane of case 2 flitch 8 to solved current diverter valve during operation, the material that scatters is easily piled up the material mixture that leads to on the surface of sealed case 2, influences the problem of enterprise's production.
