Thermostatic regulator for solar water heater faucet

Abstract

The invention discloses a thermostatic regulator for a solar water heater faucet, which comprises a shell provided with a cold water inlet, a hot water inlet and a mixed water outlet. A flow valve and a temperature control valve are arranged in the shell, the flow valve is connected with the cold water inlet and the hot water inlet, a cold water channel and a hot water channel are arranged in the flow valve, double-control ceramic cartridges for controlling cold water flow and hot water flow are arranged on the cold water channel and the hot water channel, water outlets of the cold water channel and the hot water channel on the flow valve are connected with different water channels of the temperature control valve respectively, at least two separated water channels are arranged in the temperature control valve, a mixed water cavity is arranged at the tail end of each water channel, a thermostatic cartridge is mounted in each mixed water cavity communicated with the mixed water outlet, and filter screens are mounted in the water channels of the temperature control valve. The temperature control valve and a filter valve are integrated, so that the integral structure is more compact, water leakage caused by poor sealing fit is decreased, and reliability of practical application of the thermostatic regulator is ensured.

Description

technical field [0001] The invention relates to a water heater regulator, in particular to a thermostatic regulator used for a solar water heater faucet. Background technique [0002] At present, solar electric water heaters generally adopt two types of drop type or pressure-bearing type. The drop type electric water heater mainly relies on setting the electric water heater at a high place, and uses the potential energy of the electric water heater and the water drop to form the water supply pressure. There is a large gap between the water supply pressure of water and cold water. Usually, the pressure of cold water supply is several times that of hot water, which will easily cause cold water to pour into the hot water supply channel, thereby affecting the normal operation of the electric water heater. The water channel is equipped with a one-way check valve to prevent backflow, but the one-way check valve will further increase the water resistance and further reduce the pres...

Problems solved by technology

However, a filter valve body needs to be installed in the general thermostat, which is costly and increases the possibility of water leakage due to poor sealing fit.
