Abstract
A straight-through type powder material rubber tube valve comprises a connection cap, a valve body, a rubber tube, a bolt, a gasket, a connection flange, a safety valve, air inlets and two limit pieces. The rubber tube is positioned in the valve body and clamped and fastened through the connection cap and the connection flange to form closed space between the inner cavity of the rubber tube and the external circular surface of the valve body. Each of the two limit pieces is installed on the end face of one end of a limit piece supporting rod and positioned in the valve body. The two limit pieces are arranged on a casing of the valve body symmetrically through the limit piece supporting rods and positioned on two sides of the rubber tube. A three-way air inlet is formed in one end of each of the two limit piece supporting rods, and the safety valve is arranged on one of the air inlets. By means of the straight-through type powder material rubber tube valve, gathering of powder materials at the narrow position of the valve body is avoided, and possibility of material blockage is eliminated. Accurate control on the flow rate of the materials is achieved by controlling opening of the valve. Furthermore, when the dangerous materials contact with rubber directly, violent extrusion and friction cannot occur, and therefore, safety performance is high. Accordingly, the straight-through type powder material rubber tube valve is particularly applicable to workplaces where the powder materials have risk of burning.
