Scrubber nozzle side leakage prevention three-way check valve and scrubber

The scrubber nozzle side leakage prevention three-way check valve comprises a valve body, a spring and a sealing rubber head, the bottom end of the valve body is open, a water passing hole is formed in the top end of the valve body, one end of the spring is installed at a water outlet of a three-way joint, the other end of the spring is installed on the sealing rubber head, and the sealing rubber head is installed on the valve body. The elastic force of the spring enables the sealing rubber head to automatically abut against the water passing hole. The three-way check valve for preventing side leakage of the scrubber nozzle has the advantages that the check valve is arranged at the three-way water outlet, so that water flow can normally enter the nozzle to work, and after the scrubber is shut down, due to the one-way circulation function of the check valve, the phenomenon that the scrubber is prone to falling off due to the fact that the scrubber is obliquely placed is avoided. Therefore, water stored in the
