Abstract
The utility model provides a non-return filtering stop valve which is capable of discharging sewage directly, comprising a valve body on which a valve core installing chamber, a filter net installing chamber and a non-return valve core installing chamber which are mutually communicated are arranged. One end of the valve core installing chamber is provided with a water inlet, and one end of the non-return valve core installing chamber is provided with a water outlet. The utility model is characterized in that: a drain outlet is arranged on the valve body of the lower part of the filter net installing chamber, and the drain outlet is sealed by blocking device liquid. When the filter net installing chamber is cleaned, a filter net can be cleaned and the dirt of the filter net installing chamber can be cleared only by opening a blocking component, and thus the clearing of the dirt in the filter net installing chamber and the cleaning of the filter net are convenient.
