Abstract

The invention relates to a valve with a purging structure. The valve comprises a valve body, a valve element and a valve element driving device, a flow channel is formed in the valve body and is provided with a communicating end communicating with an equipment tank body and a cut-off opening in sealing fit with the valve element, and the valve element driving device drives the valve element to beclose to or away from the cut-off opening to form cut-off and communication of the flow channel; an area, located between the communicating end and the cut-off opening, of the flow channel serves as acommunicating area, a plurality of purging openings are formed in the area, located in the communicating area, of the flow channel, purging channels extending to the outer side of the valve body fromthe flow channel are formed in the positions, corresponding to the purging openings, of the valve body, and the positions, located on the outer side of the valve body, of the purging channels communicate with an air source. By the adoption of the scheme, the valve with the purging structure can prevent a material static area from being generated between a stirrer and the valve, and therefore themoisture content or uniformity of materials is guaranteed.

Description

technical field [0001] The invention relates to the field of material drying or equipment tanks, in particular to a valve with a purging structure. Background technique [0002] In the pharmaceutical industry, some materials need to be dried or mixed to make the moisture content or uniformity of the materials meet the process requirements, and the operation process is fully enclosed to avoid contamination by foreign matter or microorganisms. [0003] Drying or equipment tanks are often equipped with valves for discharging materials, and in order to avoid metal foreign objects caused by scraping between the agitator and the valve during agitation, a certain amount of safety is often reserved between the agitator and the valve. gap. However, because of the setting of the safety gap, there will be a material static area between the agitator and the valve where the material cannot flow. Since the material in the static area cannot participate in the complex diffusion process, t...
