Abstract

The invention relates to an electromagnetic valve capable of preventing sewage reflux. A water inlet and a water outlet are formed in a valve body; a valve seat is arranged on a water inlet channel and a water outlet channel of the valve body; a diaphragm is matched on the valve seat; a back pressure cavity is formed between the diaphragm and a valve cover and is connected with a guide valve seat;an electromagnetic valve assembly comprising an electromagnetic coil is matched on the guide valve seat; a one-way valve is arranged on a water outlet direction channel of the valve seat; one side ofa rear cavity of a water outlet direction of the one-way valve communicates with the water outlet; a valve seat carrier is connected to the other side of the rear cavity; an atmosphere opening valveseat is arranged on the valve seat carrier; a valve seat surface of the atmosphere opening valve seat faces the rear cavity; an atmosphere opening valve element is matched on the atmosphere opening valve seat; and an atmosphere opening cavity communicating with atmosphere is connected onto the valve seat carrier and communicates with the atmosphere opening valve seat. The electromagnetic valve provided by the invention is suitable to be used as a flush toilet flushing water inlet valve.

Description

technical field [0001] The present invention relates to a solenoid valve, in particular to a solenoid valve for flushing a toilet. Background technique [0002] The toilet is commonly known as the toilet, and its flushing methods usually include a flush type and a siphon type. In some cases, such as the water supply pipeline is cut off, the pressure on the water inlet side of the toilet flushing water inlet valve decreases, and a so-called negative pressure occurs. At this time, the dirty water in the direction of the water outlet side of the valve will siphon back to the water inlet side, polluting the water inlet side piping system. Therefore, the toilet flushing system including the water inlet valve needs to prevent negative pressure backflow. The outlet of the water inlet valve outlet connecting pipe for toilet flushing is located in the toilet. In the prior art, this kind of water inlet valve has two water outlets, and one water outlet is connected to the flushing si...
