Problems solved by technology

[0004] The control valve is installed in the explosion-proof area of ​​the switch or connected to the metering valve after being connected to a separate wiring pipe. Due to the chaotic installation that may occur during the maintenance and repair of the metering system, it is difficult to accurately distribute the metering valve to each metering valve. to its corresponding control valve
[0005] Moreover, the current internal sealing mechanism of the existing control valve is complicated, and the precise cooperation between the components is used to ensure that the conveyed material will not leak into the valve core. Even so, a small amount of leakage is inevitable

Abstract

The invention provides an electromagnetic drive switching valve. The electromagnetic drive switching valve can be used for feeding and discharging in the product preparation process adopting the automatic control mode. The electromagnetic drive switching valve is simple in structure, low in cost and convenient to mount. Through the energization and power-off of an electromagnet, the turning-on andturning-off of the electromagnetic drive switching valve are realized; the dosing action of a metering valve is completed; the whole action is simple and reliable; the practicability is high; the defects that an existing drive switching valve is high in cost and large in mounting workload are overcome; and through the use of an integrally formed corrugated pipe sealing device, the reliability ofvalve sealing is further improved, manufacturing and mounting are easier and more convenient, and the electromagnetic drive switching valve is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of metering valves, in particular to an electromagnetically driven switching valve. Background technique [0002] At present, in the product preparation process, liquid mixtures composed of various components are often prepared through liquid dosing units, such as flavors, spices, pigments and other components, and the flow rate of liquid mixtures is measured by using a weight or volume metering system. [0003] The metering system includes multiple metering valves and control valves, and the metering valves can be opened and stopped immediately through the control valves. The control valves are installed directly on each metering valve, and in systems with special explosion-proof conditions, the control valves also need to be installed in the control cabinet. [0004] The control valve is installed in the explosion-proof area of ​​the switch or connected to the metering valve after being connected to a sep...
