[0002] In the water heater in the related art, in order to achieve safe pressure relief and sewage discharge, a safety valve and a sewage valve are respectively installed on the inner tank, so that both the safety valve and the sewage valve must be installed when the whole machine is assembled, and the cost is relatively high.
In order to reduce the cost, some water heaters omit the drain valve, which makes the internal cleaning very inconvenient

The invention discloses a pollution discharge safety valve and a water heater adopting the same. The pollution discharge safety valve comprises a valve body, a three-way part, a control element, a check valve component and a release component, wherein a water inflow channel, as well as a water outlet channel and a release channel that are both communicated with the water inflow channel, and a pollution discharge channel communicated with the water outlet channel are formed in the valve body; the three-way part is arranged in the valve body and can rotate between a water inflow position enabling the water inflow to be communicated with the water outlet channel and enabling the pollution discharge channel to be closed and a pollution discharge position enabling the water outlet channel to be communicated with the pollution discharge pollution discharge and enabling the water inflow channel to be closed; the control element is connected with the three-way part to control the three-way part to rotate between the water inflow position and the pollution discharge position; the check valve component is arranged in the water inflow channel; the release component is arranged in the release channel and can rotate between a release position enabling the release channel to be opened and a closing position enabling the release channel to be closed. The pollution discharge safety valve has various functions of one-way water flowing, safe pressure release and pollution discharge.
Description
technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a blowdown safety valve and a water heater provided with the blowdown safety valve. Background technique [0002] In the water heater in the related art, in order to achieve safe pressure relief and sewage discharge, a safety valve and a sewage valve are respectively arranged on the inner tank, so that both the safety valve and the sewage valve must be installed when the whole machine is assembled, and the cost is relatively high. In order to reduce costs, some water heaters omit the drain valve, which makes it very inconvenient to clean inside. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a sewage discharge safety valve, which has multiple functions of one-way water passage, safe press...
