Embodiment Construction

[0033] In order to facilitate those skilled in the art to better understand the essence of the present invention, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 As shown, a central gas water heater with a memory alloy check valve includes: a water heater body 1, a main controller 2 installed on the water heater body 1, a heat exchanger 3, and a cold water inlet pipe connected to the heat exchanger 3 4. The hot water outlet pipe 5, the water point 6 connected to the hot water outlet pipe 5, and the cold water branch pipe 7 connected between the water point 6 and the cold water inlet pipe 4; it is characterized in that at the farthest water point There is a memory alloy one-way valve 8 that connects the hot water outlet pipe 5 and the cold water branch pipe 7, and the memory alloy one-way valve 8 reduces the valve opening as the temperature rises; The directi...

Abstract

The invention discloses a central gas water heater with a memory alloy check valve, comprising: a water heater body, a main controller installed on the water heater body, a heat exchanger, a cold water inlet pipe and a hot water outlet pipe connected to the heat exchanger , the water point connected to the hot water outlet pipe, and the cold water branch pipe connected between the water point and the cold water inlet pipe; there is a memory alloy one-way pipe connecting the hot water outlet pipe and the cold water branch pipe at the farthest water point valve, the memory alloy one-way valve reduces the opening of the valve as the temperature rises; the hot water outlet pipe, memory alloy one-way valve, cold water branch pipe and cold water inlet pipe form a circulation loop, and the circulation loop is provided with the main The water flow sensor and circulating water pump connected to the controller. The present invention can judge whether to heat the water in the hot water pipe to the set temperature according to the change of circulating water flow rate, so as to ensure that the water in the hot water pipe is hot water, and the water in the cold water pipe is cold water. It also realizes instant opening and cooling.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a central gas water heater with a memory alloy check valve. Background technique [0002] When the current central gas water heater uses the cold water pipe at the water point as the return pipe of the preheating cycle, a check valve will be installed between the cold water pipe at the farthest water point and the water heater pipe to connect the cold water pipe and the hot water pipe. The water heater, the hot water pipe, the one-way valve, and the cold water pipe form a circuit by connecting them through a one-way valve, and the water in the circuit is heated in advance before taking a bath to achieve the effect of instant heating. [0003] In actual work, the temperature of the return water end (cold water end) of the water heater is used as the judgment condition, that is, when the temperature of the water return end of the water heater reaches the set value, the circulating w...
