Including a miniature pump with check valve, the valve body and can tear open outfit way fixed installation in the inlet pipe of the body, the inlet pipe is a water channel, the lower the inlet pipe into the valve body, and the inlet pipe bottom and the body wall form at least one water channel, the lower the inlet pipe has at least one outlet, the outlet is connected into the water channel and water channel, The lower end of the inlet pipe is covered with a one-way elastomer spool, the lower end of the one-way elastomer spool has at least one elastic valve tongue, the elastic valve tongue is combined with the cover of the water outlet at the lower end of the inlet pipe, when the water pressure of the water channel is far greater than the water pressure of the water channel, the water outlet channel and the water inlet channel is connected; When the water pressure of the outlet channel is greater than that of the inlet channel, the outlet channel and the inlet channel are isolated. Simple structure, small size, low manufacturing cost and maintenance cost, and the co
ntrol effect is ideal, has a strong market competitiveness.
