Backwash water valve with water line filter cup

The backwash water valve for the filter cup is a valve used in the poultry breeding water line system for backwashing the filter cup. The following is its related introduction:

Working principle

Usually it is a two-way three-way structure. In normal working condition, water flows into the filter cup through the backwash water valve, and is filtered through the filter screen. Impurities are trapped inside the filter screen, and the filtered water flows out for poultry to drink. When backwashing is required, the controller will send a signal (for automatic backwashing systems) or manually operate the valve to switch the working state, close the normal water supply channel, and open the backwashing channel. At this point, the direction of the water flow changes and flows in the opposite direction from the outlet end of the filter cup. It flushes the filter screen at a higher flow rate, removing impurities trapped on the filter screen. The flushed wastewater is discharged through the sewage outlet.

Characteristics and advantages

Maintain clean water quality: Regular backwashing can effectively remove impurities, dirt, and microorganisms from the filter cup, prevent filter clogging, protect the smooth flow of water and clean water quality in the water line, provide clean and hygienic drinking water for poultry, and help reduce the occurrence of actual diseases in poultry.

Extend the service life of the filter cup: By timely removing impurities from the filter screen, reducing the pressure loss of the filter screen, and minimizing the possibility of damage to the filter screen due to long-term blockage, the service life of the filter cup and the entire water line system can be extended.

Easy to operate: Whether it is an automatic backwash water valve or a manual backwash water valve, the operation is relatively simple. The automatic backwash water valve can automatically start the backwash program according to the set time or pressure difference, without frequent manual intervention; The manual backwash water valve can be operated by manually turning or rotating the valve handle, which is convenient and fast.

Save water resources: During the backwashing process, only a small amount of water is needed to clean the filter screen, which is more water-saving and reduces breeding costs compared to traditional methods such as regularly replacing filter elements or flushing the water line with a large amount of water.

Installation and Maintenance

Installation: The backwash water valve is generally installed near the waterline filter cup for easy connection between the filter cup and the sewage pipeline. During installation, it is necessary to confirm that the valve is installed in the correct direction, firmly connected, and avoid water leakage. At the same time, the installation position of valves should be reasonably selected according to the layout and actual needs of the water line system, in order to facilitate operation and maintenance.

Maintenance: Regularly check the sealing performance of the backwash water valve, and replace the sealing components in a timely manner if there is any leakage; Check whether the operating mechanism of the valve is flexible. If there is any jamming or insensitivity, lubricate or repair it in a timely manner; Regularly clean the sewage outlet to prevent blockage and affect the backwash effect.
