Abstract
The utility model discloses a safety valve for water heater with preset constant temperature outlet which contains a valve body and outlets and inlets of the cold water and hot water and characterized in that the outlets and inlets of the cold water and hot water are arranged on the one-body preset constant temperature outlet valve. The inner one-body preset constant temperature outlet valve is provided with a mixing chamber, the inner mixing chamber is provided with a valve, and the corresponding side of the valve is provided with a heat expansion piston. The mixing chamber can be communicated with the hot water inlet by a by-pass channel, the back of the heat expansion piston exists a variable water flow channel with the hot water outlet, and the cool water inlet is communicated with the back and the cool water outlet of the valve. Fixing nuts are welded in the outlets and inlets of the cold water and hot water of the valve to form an external seal type, or fixing nuts are welded in the inlet of the cold water and the outlet of the hot water, and the other end is a communication pipe which connects a water heater to form a built-in type valve.
Description
Technical Field
The utility model relates to a preset constant temperature export water heater relief valve.
Background
Generally speaking, a water heater generally adopts a common mixing valve to adjust the outlet water temperature, or adopts a water flow adjusting device, or adopts a temperature control adjusting device, and the prior art has the following disadvantages:
1. the water flow temperature often lags due to the heating device, which affects the accuracy of the adjustment.
2. The difference in the size of the water flow makes the fluctuation of the mixing temperature large, and the adjusting effect is also influenced to a certain extent.
3. Once the temperature of the water flow is too hot, the human body may be scalded.
The utility model discloses the content
The utility model aims at providing a preset constant temperature outlet safety valve of a water heater.
The above object of the present invention is achieved by the following technical solutions:
the water heater safety valve with the preset constant temperature outlet comprises a valve body, a cold water inlet, a hot water outlet and a hot water outlet, and is characterized in that: and the cold and hot water inlet and outlet are fixedly arranged on the same preset constant temperature outlet valve.
The one-piece preset constant-temperature outlet valve is internally provided with a mixing chamber, one side of the mixing chamber is provided with a valve, the opposite side of the valve is provided with a thermal expansion piston, the rear part of the thermal expansion piston and a hot water outlet have a variable water flow channel, and a cold water inlet is communicated with the rear part of the valve and a cold water outlet.
The mixing chamber is communicated with a hot water inlet through a bypass channel.
The cold and hot water inlet and outlet of the valve are welded with fixed nuts to form an externally-mounted valve, or,
and fixing nuts are welded on the cold water inlet and the hot water outlet of the valve, and a communicating pipe connected with a water heater is arranged at the other end of the valve to form the built-in valve.
Because the utility model adopts the above technical scheme to can utilize the thermal expansion piston to take place the displacement according to the change of temperature in the valve, adjust the relative flow of hot and cold water, when the temperature was overheated, the thermal expansion piston can seal the indisputable bypass passageway of hot water, and cold water makes the temperature decline in the water heater in flowing into the water heater through the cold water inlet.
