Abstract

The utility model relates to a duct thermostat for a water heater, which is formed by the connection of a variable diameter pipe, a branch pipe communicated with a cold water inlet pipe and a hot water outlet pipe, a thermoregulation valve of a warm water pipe and a flow valve, wherein, cold water flows towards a smaller pipe-diameter end from a larger pipe-diameter end; the thermoregulation valve connected in series with the branch pipe which is placed at the connection point of the smaller pipe-diameter end of the variable diameter pipe and the warm water pipe and is communicated with a hot water outlet pipe to regulate water temperature. When the utility model is used, the independent regulation thermoregulation valve and the flow valve can complete the regulation to the temperature and the flow of mixed warm water, and do not generate interference for each other. Even if external factors are changed, the utility model can keep a constant water temperature.

Description

A kind of water heater constant temperature adjusting device

The utility model relates to a kind of improvement invention to existing water heater register.

The general in the past hot water or cold water of the employing valve of water heater cooperates the water temperature and the water yield of adjusting its output hot water; When source pressure fluctuation, or when artificially changing output water temperature or flow, often need to adjust repeatedly two valves and make it to tie in, just can reach satisfaction, the water temperature that is in course of adjustment is normal cold excessively, overheated, and the water yield is excessive, too small, both are confused to interfere with each other, and influence is used.

The purpose of this utility model provides a kind of water heater constant temperature adjusting device, and it can change in extraneous factor, keeps the constant of water temperature, and adjustment process is simple, quick.

The utility model has adopted speed change jetting vacuum siphon principle: the variation of the cold water stream in cold water road at two different tube diameters place flow velocitys often opened in utilization, form corresponding different tube diameters place vacuum differential static pressure, utilize this differential static pressure to impel hot water circuit simultaneously and infiltrate cold water stream to merge into use warm water.Because the variable quantity of cold water flow velocity has reacted static pressure difference variable quantity, this static pressure difference variable quantity again positive reaction the flow rate of hot water variable quantity, the variation of hot water or cold water's flow velocity reaches synchroballistic, so finally the ratio of its hot water or cold water's flow velocity is stable, corresponding hot water or cold water's mixing ratio is also constant.

The utility model structure is seen shown in the accompanying drawing, it is characterized in that it comprises a reducer pipe and is attached thereto logical warm water tube, and there is an arm that is connected with the cold water inlet of water heater at the big caliber of reducer pipe place simultaneously; Temp regulation valve be serially connected with the reducer pipe tubule directly hold with the warm water tube junction and with arm that the water heater hot-water outlet pipe is communicated with on, the warm water flow valve is arranged on the warm water pipeline.Cold water flows to tubule from the big caliber end of reducer pipe and directly holds.

The above-mentioned temp regulation valve of the utility model also can be serially connected with on the big caliber end of reducer pipe and the arm that the water heater cold water water inlet pipe is connected.

The utility model is simple in structure, easy-to-use, when regulating the warm water temperature and the water yield, need only regulate relevant temp regulation valve and flow valve separately, can satisfy instructions for use, and not disturb mutually each other, adjustment process is simple, quick, react soft, thereby be a kind of desirable water heater register.

Accompanying drawing has been described an embodiment of the present utility model:

Fig. 1 is a structural representation of the present utility model.

In the accompanying drawing 1, reducer pipe 1 big caliber place has an arm 3 to be connected with the water heater cold water water inlet pipe, its tubule is directly located to be connected with warm water tube 2, and two pipe connections place are provided with an arm 4 and are connected with the water heater hot-water outlet pipe, arm 4 is provided with temp regulation valve 5, and flow valve 6 is arranged on warm water tube 2 pipelines.

Use of the present utility model is performed such, and screws flow valve 6 earlier, and temp regulation valve 5 then needn't screw, and after waiting to enter the cold water temperature rising of water heater, can open flow valve 6 and carry out bathing; Undesirable as water temperature, at this moment can regulate temp regulation valve 5, it is low to turn down water temperature, opens big water temperature height, and it is constant to mix up back warm water water temperature, does not also influence water temperature after mixing up even open large-capacity valve door 6 again.

Claims

1. a water heater constant temperature adjusting device is characterized in that it comprises a reducer pipe and is attached thereto logical warm water tube; Wherein there is an arm that is connected with the water heater cold water water inlet pipe at the big caliber of reducer pipe place, and the little caliber of reducer pipe and warm water tube junction are provided with the arm that is connected with the water heater hot-water outlet pipe; Temp regulation valve is serially connected with on arbitrary arm, and warm water tube is provided with flow valve.
