Abstract
The utility model discloses a floating ball check valve and a cold water and hot water mixing faucet. The floating ball check valve comprises a valve body, a filter net and a floating ball, wherein the valve body comprises an inner cavity, the inner cavity of the valve body is communicated with a water outlet in the top, the lower part of the inner cavity comprises a valve base, a water hole in the lower part of the valve base is communicated with a water inlet in the bottom of the valve body, the filter net is arranged on the middle of the inner cavity, and the floating ball is positioned between the filter net and the valve base. The cold water and hot water mixing faucet comprises a hot water inlet, a cold water inlet, a water outlet and the floating ball check valve, wherein the floating ball check valve is arranged below the hot water inlet, and the water outlet in the top of the floating ball check valve is connected with the hot water inlet. According to the utility model, the waste of hot water resources because cold water in a system enters in a hot water pipeline can be prevented, and thus the heat efficiency of a hot water system is increased.
Description
[technical field]
The utility model relates to water heating system, relates in particular to a kind of float non-return valve and cold-hot water mixing water tap.
[background technique]
When using electric water heater, during hot water in solar water heater, need to utilize combustion taps to regulate water temperature.Because the influent pressure of combustion taps cold water inlet is often greater than the intake pressure of water inlet of hot water, cold water easily occurs and seals in phenomenon in water inlet of hot water in the conventional hybrid water tap, can cause the cold water in cold water pipe to seal in the hot water tank of water heater when serious, cause the waste of thermal water resource.
[summary of the invention]
The technical problems to be solved in the utility model is to provide the float non-return valve that a kind of cold water is not easy to seal in the combustion taps water inlet of hot water.
Another technical problem that will solve of the utility model is to provide the combustion taps that a kind of cold water is not easy to seal in water inlet of hot water.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of float non-return valve, comprise valve body, filter screen and ball float, described valve body comprises inner chamber, the inner chamber of valve body communicates with the water outlet at top, the bottom of inner chamber comprises valve seat, and the water hole of valve seat bottom communicates with the water intake of valve body bottom; Described filter screen is arranged in the middle part of inner chamber, and described ball float is between filter screen and valve seat.
Above-described float non-return valve, described ball float is hollow spheres.
Above-described float non-return valve, described hollow spheres are the stainless steel hollow spheress.
A kind of technological scheme of cold-hot water mixing water tap, comprise water inlet of hot water, cold water inlet, water outlet and vertical check valve, described vertical check valve is above-mentioned float non-return valve, the float non-return valve is arranged on the below of water inlet of hot water, and the water outlet at float non-return valve top is connected with water inlet of hot water.
The utility model cold-hot water mixing water tap can prevent that the cold water in locking system seals in hot water pipeline, causes the waste of thermal water resource, thereby improves the thermal efficiency of water heating system.
