Description

Angle valve with filtering capability Technical Field The utility model relates to an angle valve, in particular to an angle valve with a filtering function. Background The angle valve is not unfamiliar for the public, and the entrance and exit of house water pipe in wall position all need angle valve to connect water equipment, and water inlet and outlet channel and the angle valve of water heater are connected, and the water inlet channel of closestool is connected with the angle valve, and kitchen tap, wash basin tap are also connected with the angle valve. The basic function of the angle valve is to control the water way to be opened or closed, along with the improvement of the water quality requirement of people, not only drinking water is filtered through the water purifier, but also more people hope to carry out front-end filtration on domestic water, and the filtered water can prevent sand particles or scrap iron from entering household appliances such as a water heater, an intelligent closestool, a washing machine, a dish washer and the like.
