Automatic valve

Abstract

The invention relates to an automatic valve comprising a valve body, a liquid inlet, a plurality of liquid outlets, an isolating wall, a plurality of liquid through holes, a first piston and a second piston; the liquid inlet is formed in one side of the valve body; the plurality of liquid outlets are formed in the other side of the valve body; the isolating wall is arranged in the middle of the valve body; the plurality of liquid through holes are formed in positions, corresponding to the liquid outlets, in the isolating wall; the first piston and the second piston are respectively arranged at the upper and lower ends of a pipe cavity close to one side of each liquid outlet and used for controlling the opening and closing of the liquid outlets; and the first piston and the second piston are respectively driven by a first driving part and a second driving part to move. According to the automatic valve, the opening and closing of the valve can be realized through the drive of the driving parts; and compared with the traditional valve, the automatic valve has the advantages that switching valves arranged at the liquid outlets are omitted, and connecting nodes are reduced, so that installation and overhaul become very convenient. On the other hand, the opening and closing of the valve is controlled by a software system, so that complex manual operation is also avoided, furthermore, the probability of operation errors is greatly reduced; and meanwhile, due to the existence of an inductor, problems such as leakage can also be found as soon as possible, so that loss is avoided.

Description

technical field [0001] The invention relates to the field of valves, in particular to an automatic valve. Background technique [0002] In various pipelines such as oil pipelines, water pipelines or natural gas pipelines, and even food pipelines in the food processing industry, various valves are usually required due to line changes or additions. For example, diverter valves are required when dividing a pipeline into multiple lines. [0003] The existing diverter valve is generally provided with a liquid inlet at one end of the valve body, and a plurality of liquid outlets at the other end of the valve body. To control the opening or closing of the liquid outlet, generally a manual switching valve is set on the liquid outlet, and the valve of the liquid outlet is manually opened or closed according to actual needs. However, switching the valve manually makes the operation more cumbersome and error-prone. On the other hand, the increased number of valves makes the installa...

However, switching the valve manually makes the operation more cumbersome and error-prone

On the other hand, the increased number of valves makes the installation process complicated. When there are many diversion ports, detection and maintenance will become very troublesome, and it is easier to cause pipeline leakage
