A valve body with filter function

Abstract

The invention relates to the field of water control valves, in particular to a valve body with a filtering function, including a valve casing, the left and right sides of the valve casing are respectively fixed with a water inlet connecting pipe and a water outlet connecting pipe, and the inner center of the valve casing is fixed Rotation is connected with a rotating shaft, and a filter screen is fixed on the rotating shaft. The intermittent reciprocating motion mechanism is connected to the water inlet connection pipe, and is connected to the rotating shaft through the intermittent reciprocating motion mechanism. A sewage pipe is fixed on the lower side of the valve housing. A brush holder for cleaning the filter screen is fixed at the connection, and an automatic sewage discharge mechanism is arranged at the outlet end of the sewage pipe. This kind of valve body with filtering function can automatically clean, maintain a stable flow rate of the filter screen, and improve water delivery efficiency, so that the water pressure inside the valve body will be kept in a stable state in time, so that Structural parts are not damaged by excessive water pressure, and pipe bursts are prevented, and automatic sewage discharge can be realized, saving time and effort.

Description

Technical field [0001] The present invention relates to the field of control valve, and is specifically a valve body having a filtration function. Background technique [0002] Usually, when the work is watering the farmhouse, it is necessary to transport a long-distance water source to fields that need to be irrigated. Since the length of the water pipeline is limited, the connection is usually used in the connection. The ends of the two water pipelines are connected and connected, while the water source contains impurities in the water quality, such as muddy, float, etc., resulting in a decrease in the water side pressure of the valve body. The water is reduced, thereby reducing the water efficiency, and the water on the feed of the valve body is small due to the clogging, the pressure is gradually increased, and the pressure is gradually increased, and the valve body connection is sealed, damined, and even the phenomenon of explosion tube, Resulting in increased maintenance co...

Problems solved by technology

[0002] Usually, when watering farmland crops, it is necessary to use water pipelines to transport long-distance water sources to the fields that need to be irrigated. Due to the limited length of water pipelines, valve bodies that play a role in connection are usually used at the connections The ends of the two water delivery pipelines are connected and communicated with each other. When the water source passes through the pipeline, the water quality contains impurities, such as mud, floating objects, etc., which can easily block the valve body, resulting in a decrease in the pressure on the outlet side of the valve body. The water output is reduced, thereby reducing the irrigation efficiency, and the flow rate of the water inlet side of the valve body becomes smaller due to blockage, so the pressure gradually increases. On the one hand, the sealing of the valve body connection will become poor, damaged, and even burst. It will lead to an increase in maintenance and repair costs and aggravate the reduction in efficiency. In view of this, we propose a valve body with filtering function
