Abstract

The invention relates to a method for reducing discharging quantity of a standard part star discharge valve. The invention adopts the technical scheme that the method comprises the following steps of: calculating the discharging volume V reduced in each revolution of the standard part star discharge valve according to the actual production process requirement; determining the plugging number n ofsub cavities of the standard part star discharge valve according to the structure of the standard part star discharge valve, wherein the volume of a plugging body for each sub cavity of the standard part star discharge valve is v=V / n, and v is less than or equal to v1; and then making sub cavity plugging bodies with volume of v according to the shapes of the sub cavities of the standard part stardischarge valve, and embedding or respectively embedding the sub cavity plugging bodies into the n sub cavities of the standard part star discharge valve. The plugging bodies are hollow or solid; andthe plugging bodies are fixed on blades or a shaft in a mode of welding or bolt connection. Based on the original standard part star discharge valve, the method has the characteristics of meeting theproduction requirement, accurately controlling the discharging quantity and prolonging the service life of a motor.

Description

technical field [0001] The invention belongs to the technical field of standard star discharge valves. In particular, it relates to a method for reducing the discharge volume of a standard star discharge valve. Background technique [0002] Unloading valves are often used in industrial production equipment or test devices. The unloading valve is installed at the inlet or outlet of the equipment to control the amount of material fed or discharged. The unloading valve is a standard part, and different types and specifications of unloading valve standard parts need to be selected for different processes, material properties, production and processing capabilities. [0003] However, in the actual use of unloading equipment, especially when using small unloading equipment or unloading test devices, not all standard unloading valves that match the actual required feed volume or discharge volume can be used. Available for selection. Under normal circumstances, only the standard ...
