Abstract
The utility model relates to a double air supply gas water heater, comprising a valve body assembly and a burner assembly. The utility model is characterized in that the air vent diameter of the nozzle of the burner assembly is arranged according to the standard requirement of the used low heating value air supply; a nut type nozzle is arranged on the nozzle through threaded connection; the diameter of the center air vent of the nut type nozzle is arranged according to the standard requirement of the used high heating value air supply; the air-regulating valve core of the valve body assembly is respectively provided with a minimum gas air flow regulation hole which is designed according to the requirement of using low heating value air supply and a minimum air flow regulation hole which is designed according to the requirement of using high heating value air supply; the rotary rod of the valve core and the surface of the air-regulating valve are respectively provided with a spacer pin and a stop screw. The gas water-heater of the utility model can use two air supply with different heating values; moreover, the structure and the operation for converting air supply are very simple and are easy to carry out so that the problem that the existing gas water-heater can't use two air supply is effectively overcome.
Description
Affiliated technical field
The utility model relates to gas heater, particularly a kind of double-source gas water heater.
Background technology
Because artificial coal gas, the calorific value difference of liquefied petroleum gas and natural gas, the minimum tolerance adjustment hole diameter of the gas spray head of designed gas heater and source of the gas Air-regulating valves is also different, and therefore, the gas heater that designs according to certain source of the gas can not use other sources of the gas.Brought trouble when this limitation is changed source of the gas to people,, had to increase economic spending if the original hot device of combustion gas that uses high heating value because the diameter of its nozzle is smaller, must entrust the maintenance station reaming to realize the source of the gas that combustion heat value is lower; If original gas heater is to use low-calorie source of the gas, desire to use instead the high heating value source of the gas and just can't realize, can only scrap, this is the deficiency of existing gas heater just.
Summary of the invention
In order to overcome the weak point that existing gas heater exists, the utility model provides a kind of double-source gas water heater that uses two sources of the gas.
Above-mentioned task realizes by this way: a kind of double-source gas water heater comprises valve body assembly and burner assembly, the venthole diameter that it is characterized in that the nozzle of burner assembly is offered by the standard-required of employed low heat value source of the gas, nut type nozzle by being threaded and offering by employed high heating value source of the gas standard-required with a center venthole diameter on nozzle, on the Air-regulating valves spool of valve body assembly, be respectively equipped with one by the minimum tolerance adjustment hole that uses the design of low heat value source of the gas and one by the minimum tolerance adjustment hole that uses the design of high heating value source of the gas, and on the swingle of spool and the surface of Air-regulating valves be respectively equipped with one in order to limit the spacer pin and the stop screw of low heat value source of the gas tolerance adjustable range.
The utility model is like this work: when gas heater needs lower heat of combustion source of the gas (as natural gas etc.), the nut type nozzle is taken out, this moment, the nozzle of burner assembly was a low heat value source of the gas nozzle, meanwhile, load onto stop screw on the Air-regulating valves surface, make the spool of dual gas supply control valve in the scope of low heat value source of the gas, regulate tolerance.This moment, gas heater can use the low heat value source of the gas.When needs use high heating value source of the gas (as liquefied petroleum gas etc.), the nut type nozzle can be threaded on the nozzle of burner assembly, its venthole diameter is reduced, meanwhile, stop screw is screwed out, the spool of dual gas supply Air-regulating valves can freely be transferred on the minimum tolerance position of high heating value source of the gas, thereby make gas heater can use the high heating value source of the gas.This shows, improvement of the present utility model not only makes gas heater can use the source of the gas of two kinds of different calorific values, and the structure of conversion source of the gas is very simple with operation, implements easily, can not use two kinds of problems that source of the gas brought thereby overcome existing gas heater effectively.

The specific embodiment
As shown in Figure 1, a kind of double-source gas water heater, comprise valve body assembly 1 and burner assembly 2, its improvements are that the venthole diameter of the nozzle 21 of burner assembly 2 is to offer by the standard-required of employed low heat value source of the gas, on nozzle 21 by the screw thread nut type nozzle 22 (as shown in Figure 2) that a center venthole diameter offers by the standard-required of employed high heating value source of the gas that spins, on the Air-regulating valves spool 11 of valve body assembly 1, be respectively equipped with one by the minimum tolerance adjustment hole 12 that uses the design of low heat value source of the gas and a minimum tolerance adjustment hole 13 by the design of use high heating value source of the gas, and be provided with a spacer pin 14 that limits low heat value source of the gas tolerance adjustable range at the swingle of Air-regulating valves spool, be provided with a corresponding stop screw 15 (shown in Fig. 3～5) on the surface of control valve.
The parameter of an embodiment of the utility model.
Use source of the gas: liquefied petroleum gas and natural gas.
Minimum tolerance adjustment hole 12 diameters of natural gas: 2.2 millimeters.
The minimum tolerance adjustment hole of liquefied petroleum device 13 diameters: 1.5 millimeters.
Claims (1)
1. double-source gas water heater, comprise valve body assembly (1) and burner assembly (2), the venthole diameter that it is characterized in that the nozzle (21) of burner assembly (2) is offered by the standard-required of employed low heat value source of the gas, go up the nut type nozzle of offering by employed high heating value source of the gas standard-required with a center venthole diameter by being threaded (22) at nozzle (21), on the Air-regulating valves spool (11) of valve body assembly (1), be respectively equipped with one by the minimum tolerance adjustment hole (12) that uses the design of low heat value source of the gas and one by the minimum tolerance adjustment hole (13) that uses the design of high heating value source of the gas, and on the swingle of spool (11) and the surface of Air-regulating valves be respectively equipped with one in order to limit the spacer pin (14) and the stop screw (15) of low heat value source of the gas tolerance accent scope.
