The invention discloses an engineering plastic tee joint beneficial to installation. The engineering plastic tee joint beneficial to installation comprises installation flanges, connection pipes, a control valve, a tee joint body and filter covers. The filter covers are fixedly mounted at the tops of the connection pipes through installation openings. The installation flanges are fixedly mounted at the ends of the connection pipes. The connection pipes are fixedly mounted at the bottoms of the two ends of the tee joint body. A control valve is fixedly mounted at the top of the tee joint body.According to the engineering plastic tee joint beneficial to installation, the installation flanges are arranged, a pipeline can be directly fixedly installed through the installation flanges and doesnot need to be wrapped with waterproof tape, and thus, the pipeline and the tee joint can be connected conveniently and rapidly; and the engineering plastic three joint beneficial to installation isprovided with the filter covers, and a water source flowing through the tee joint can be filtered through the filter covers, so that the cleanliness of the water source is ensured, and the tee joint can be cleaned by dismantling the filter covers after being used for a period of time.
