Abstract
The utility model provides a gas/vapor double function diaphragm valve for a water heater, which comprises a water-gas interstage valve. The utility model is characterized in that the back side of the water-gas interstage valve is provided with a diaphragm type vapor-gas interstage valve composed of a diaphragm chamber, a diaphragm and a valve rod. A valve rod of the water-gas interstage valve is connected with the diaphragm of the vapor-gas interstage valve, a strip of channel with a flow control valve is arranged between a right chamber of the vapor-gas interstage valve and the left chamber of the water-gas interstage valve, a strip of channel communicated with a water outlet is arranged on the left chamber of the water-gas interstage valve, and the lower end of the right chamber of the vapor-gas interstage valve is provided with a water inlet. Hot water or vapor can be generated by the existing water heater by using the utility model which has the advantages of simple structure and easy use.
Description
The utility model relates to membrane valve, the difunctional membrane valve of particularly a kind of combustion and steam-water heater.
Gas water-heater commonly used can only produce hot water, is difficult to produce steam, and its reason is will produce steam the water yield must be reduced to certain value and could realize, and that the minimizing water yield may cause is flame-out, water can't be heated into steam.In order to address this problem, the water heater that has cuts off fully by the control of combustion gas and the control of flow, and electronic control circuits such as employing thermocouple regulate and control to realize that its deficiency is the use that influences the normal heat hydrophone, are difficult to obtain suitable water temperature; Have then on water tank a closed steam chamber of design and the control valve that is interconnected realize that but complex structure, the thermal efficiency are low.
The purpose of this utility model is the problem that exists at the above-mentioned background technology, provides a kind of simple in structure, easy to use, both can make water heater produce hot water, can produce the difunctional membrane valve of combustion and steam-water heater of steam again.
Task of the present utility model realizes by this way: this difunctional membrane valve includes an aqueous vapor interstage valve, the back side that it is characterized in that the aqueous vapor interstage valve is provided with one by chamber of septum, the diaphragm type vapour gas interstage valve that barrier film and valve rod constitute, the valve rod of aqueous vapor interstage valve passes the valve wall of sealing and the diaphragm center of vapour gas interstage valve links, on the valve wall between vapour gas interstage valve right ventricle and the chamber, an aqueous vapor interstage valve left side, be provided with a passage, and on passage, be provided with a flow control valve, on chamber, an aqueous vapor interstage valve left side, have a passage that is communicated with aqueous vapor interstage valve water outlet, be provided with water intake in lower end, vapour gas interstage valve right ventricle.
During use, basically equally the utility model is installed in the water heater by existing aqueous vapor interstage valve, the water outlet that is about to the aqueous vapor interstage valve is connected with heat exchanger, the valve rod of vapour gas interstage valve is connected with suction valve with the ignition mechanism switch, and the water intake of the water intake of aqueous vapor interstage valve and vapour gas interstage valve is connected with the water source by a solenoid electric valve.When the needs water heater produces hot water, utilize solenoid electric valve to close the water intake of vapour gas interstage valve, open aqueous vapor interstage valve water intake, make water enter the right ventricle of aqueous vapor interstage valve, promote its barrier film and expand left, valve rod moves to left, barrier film by vapour gas interstage valve promotes its valve rod also to moving to left, cause ignition mechanism sparking, open the air valve burning simultaneously, enter water in the heat exchanger and be heated to form hot water after shower sprays outward for people has a bath.Finish having a bath, when closing the water source, its return spring is turned right barrier film and is drawn, and valve rod moves to right, and closes source of the gas.And when needs steam, close the water intake of aqueous vapor interstage valve by solenoid electric valve, and make water enter its right ventricle through the water intake of vapour gas interstage valve, its barrier film is expanded left, valve rod moves to left, and is the same with above-mentioned principle, and combustion gas is lighted.Meanwhile, the water that enters the right ventricle produces the left chamber that the little high pressure water of flow enters the aqueous vapor interstage valve by passage between two valves and flow control valve, again through the passage on top, left chamber in the water outlet inflow heat exchanger, because its flow is smallerly controlled, enter and be easy to vaporization in the heat exchanger and produce steam, spray outward from shower.This shows, make it just can produce hot water or steam, realized the purpose of this utility model, and this valve arrangement is simple, use very convenient to the aqueous vapor interstage valve or to the water supply of vapour gas interstage valve as long as handle electromagnetic controller.
Below in conjunction with accompanying drawing structure of the present utility model is further described.
Fig. 1 is a kind of concrete structure of the utility model sectional view longitudinally.
As shown in the figure, the structure and the prior art of aqueous vapor interstage valve 1 are basic identical, mainly are made of chamber of septum 2, barrier film 3, valve rod 4, return spring 17, water intake 5 and water outlet 6.Vapour gas interstage valve 7 is by chamber of septum 8, and barrier film 9 and valve rod 10 constitute, and tightly place the back side of aqueous vapor interstage valve 1, and the valve rod 4 of aqueous vapor interstage valve 1 passes the valve wall and is connected with barrier film 9 centers of vapour gas interstage valve 7.The attachment portion of aqueous vapor interstage valve 1 and vapour gas interlock 7 can a shared valve wall 11, has the passage 12 of the left chamber of a right ventricle that links vapour gas interstage valve 7 chamber of septum 8 and aqueous vapor interstage valve 1 chamber of septum on valve wall 11.Flow control valve 13 is arranged on the passage 12, with the flow of control water.Be provided with a passage 14 that is communicated with its water outlet 6 in the left chamber of aqueous vapor interstage valve 1 chamber of septum 2, this passage 14 can be arranged in the valve wall of aqueous vapor interstage valve 1 and vapour gas interstage valve 7.The water intake 15 of vapour gas interstage valve 7 is arranged on the lower end of its membrane valve 8 right ventricles.Have a passage 16 that is communicated with chamber of septum left chambers 8 and passage 14 at vapour gas interstage valve 7, reduce the degree of vacuum of chamber of septum left chambers 8, be convenient to valve rod 10 returns.
