Abstract
The utility model relates to a water temperature regulator of a fuel gas water heater, which can be connected between a water inlet and a water outlet of a gas water heater. When the water pressure difference on both ends of the utility model reach a certain value, the utility model is suddenly opened. Consequently, a part of cold water passes by a water outlet pipe of the water heater to mix with hot water, and final water temperature is changed. The pressure difference between the water inlet and the water outlet is regulated by a total water flow regulating valve, the differential pressure is bigger, the water quantity is bigger, and the water temperature is lower. The water heater can no flame out in within a lager regulating range. The utility model mainly comprises a shell, a water inlet and a water outlet which are arranged on the shell, and a one-way pop valve which can regulate open pressure.
Description
The utility model relates to the thermostat of gas heater, and the adjusting of water temperature is carried out away from water heater.
As everyone knows, generally speaking, gas heater will be installed with the bathroom locellus, and the water temperature by-pass cock all is arranged on the water heater, simultaneously because the people that aqueous vapor interlock valve is had a bath to the specific (special) requirements (flow is too small just flame-out) of flow can't regulate water temperature in the bathroom arbitrarily, and must other people assist, this brings very big inconvenience just for the water heater user.For addressing this problem, the water heater user who has has installed hot and cold water mixing control valve in the bathroom, as long as the water temperature by-pass cock of water heater is placed on the gear of higher temperatures, just can be implemented in to regulate in a big way in the bathroom and blend coolant-temperature gage, satisfy of the requirement of water heater aqueous vapor interlock valve simultaneously discharge.Yet this installation method has not only increased installation cost, and makes the high-temperature water longer pipe road of flowing through, and certainly will cause bigger thermal loss, thereby waste energy.Especially in winter, this problem is more outstanding.
The purpose of the utility model is to provide a kind of special gas heater thermostat, thereby the people who makes bathing regulated at will water temperature in the bathroom easily also can be saved energy resource consumption simultaneously, saves the installation and the cost of use of water heater.
The gas heater thermostat of the utility model comprises: housing, be located at water inlet and delivery port on the housing, the adjustable unidirectional pop valve device of opening pressure.
The utility model can be installed in parallel between gas heater water inlet and outlet pipe, also can be installed in parallel between the front and back of the water inlet throttle orifice in the gas heater water temperature regulation device, or make itself and water inlet throttle orifice in aggregates.When using water heater, the pressure reduction of unidirectional pop valve between its water inlet and delivery port throws open when reaching certain value, and pressure reduction more then open area is bigger, thereby also just big by its discharge.This opening of valves and keep the required pressure reduction of opening should be greater than the minimum starting pressure of water heater, thereby guarantee that water heater can not stop working when regulating total water current amount (yet promptly regulating water temperature).Hence one can see that, and the leaving water temperature that gas heater of the present utility model is housed can be in very big scope (the highest water temperature: by the size of water heater water inlet throttle orifice, also be former water heater temperature's adjusting knob position and deciding; Minimum water temperature: the maximum open area by check valve is decided) in regulate by the total water current amount, and the adjusting of total water current amount can be carried out at any pipeline location (as the control valve on the bathroom interior conduit) away from water heater easily, has finally realized the purpose of the utility model.
In addition, use the thermostat of the utility model,, thereby avoided owing to long apart from the radiation loss of carrying high-temperature water to cause, so saved energy resource consumption with the hot and cold water mixing device that no longer needs to install in the bathroom.
Fig. 1 is structure and the principle schematic of one of the utility model embodiment.Be illustrated as this thermostat is parallel to occasion between water heater water inlet and the outlet pipe.
As shown in Figure 1, described thermostat comprises housing (2), housing (2) is provided with water inlet (1) that links to each other with cold water source and the delivery port that links to each other with water heater outlet (6), unidirectional pop valve body (4), valve seat (3), preloading spring (5), sealing ring (7), and cracking pressure is regulated bolt (8) etc., when making its pressure reduction of working as intake-outlet reach certain value, can open suddenly the special tectonic of valve body (4), uprushing appears in its lift, the open area of check valve is from the zero a certain minimum of a value of uprushing, and open area will change gradually with the variation of pressure reduction then.Rotate and regulate the pretightning force that bolt (8) can change compression spring (5), thus the opening pressure of regulation valve body (4).
The foregoing description, the utility model as an illustration only, but do not play the purpose that limits the utility model.Some other distortion that can know by inference this area ordinary skill under the design of the utility model (for example change the valve body shape or unidirectional pop valve are become the unidirectional valve of gradually opening; For example will intake and water outlet place is designed to three-port structure convenient and being connected of pipeline etc. again) also all belong to the protection domain of the utility model.
Claims (4)
1, a kind of gas heater thermostat, it is characterized in that keeping under the not flame-out prerequisite of water heater, can regulate the water outlet water temperature in the larger context by regulating total water flow, it comprises: housing, be located at the intake-outlet on the housing, check valve apparatus, when pressure reduction reaches certain value between intake-outlet, this one-way valve opens, and change open area with the size of pressure reduction, thus change the cold water flow of the check valve of flowing through.
2,, it is characterized in that described check valve apparatus is prominent open type, and can regulate opening pressure as thermostat as described in the right 1; It comprises: movable valve, valve seat, preloading spring, adjusting bolt.Valve body cooperates with valve seat and seals.
3, as thermostat as described in the right 2, it is characterized in that into water and water side all are provided with two connectors, can be parallel to easily between the intake-outlet of water heater, and save two three-way connections.
4, as thermostat as described in the right 1, the water inlet throttle orifice of it and water heater
Parallel connection designs and produces as a whole, replaces existing water yield thermostat.
