Abstract
The utility model relates to a gas regulator for gas utensils, which is composed of a regulating shaft assembly, an outer casing, a gas inlet pipe, a gas outlet pipe and a regulating plate; a half moon-shaped regulating plate is arranged at the lower end of the regulating shaft, an air intake plate around which periphery a group of small circular neenle-shaped through holes are bored is arranged at the horizontal position of a hollow cavity of the outer casing between the gas inlet pipe with a switch valve connected with the lower part of the outer casing and the gas outlet pipe connected with the middle part of the outer casing, and the half moon-shaped regulating plate tightly contacts with the air intake plate by a plane and can completely cover a group of small through holes. The utility model has the advantages of simple structure, convenient installation, safe use, accurate gas inlet quantity regulation, good tightness, etc.
Description
The utility model relates to the gas appliance technical field, the gas regulator that particularly a kind of gas appliance is used.
Existing gas heater is equipped with the hollow lateral opening formula adjuster of column type between gas inlet and combustion chamber, according to the requirement of leaving water temperature the combustion gas air inflow is controlled to adjust, and it is made up of shell, regulating shaft, rubber seal, cover, spring etc.The through hole that a Φ 8-10mm is arranged in the shell drilled in middle, regulating shaft and outer casing inner wall are slidingly matched, during assembling, the regulating shaft that rubber seal is housed is inserted in the shell, the cover upper spring, and screw cover, outer casing underpart is provided with fuel gas inlet, the round tube hole at shell middle part is a gas outlet, when closing, regulating shaft covers in the round tube hole of shell, and makes air flue hermetically closing between fuel gas inlet and the outlet by rubber seal, the rotation regulating shaft makes the round tube hole of shell slowly open-minded, thereby reaches the purpose of regulating the combustion gas output quantity.
The weak point of said structure is processed complex, and the gas leakage area is big, can not go to regulate exactly tolerance by setting value during use, after long-time the use, because of wearing and tearing between regulating shaft and the shell are more and more big, the gap increases, gas leakage is serious, thereby its degree of regulation reduces by a larger margin.Specifically, it can not can not cooperate electronic control circuit to carry out accurate temperature adjustment in leaving water temperature temperature adjustment below 38 ℃.
The purpose of this utility model is to provide that a kind of sealing property is good, the combustion gas air inflow is regulated the gas regulator that accurate gas appliance is used.
The purpose of this utility model is achieved in that the gas regulator that a kind of gas appliance is used, this adjuster is contained between gas inlet and the combustion chamber, it comprises shell, be contained in the gas inlet pipe of outer casing underpart, be contained in the combustion gas escape pipe at shell middle part, and regulating shaft, sealing ring, spring, cover, be fixed with inlet plate on the horizontal level between inherent gas inlet pipe of described shell inner cavity and the combustion gas escape pipe, on this inlet plate part periphery, be drilled with one group of mutual disconnected small through hole continuously; To the cover top portion cavity regulating shaft assembly of being made up of regulating shaft, sealing ring, spring, cover is housed at inlet plate, spring is contained in the cover below, and this regulating shaft bottom is a semilune adjustable plate that can cover in one group of small through hole on the inlet plate fully.The small through hole that one group of circular arc on the described inlet plate is arranged is equal diameter or non-equal diameter.The diameter of described semilune adjustable plate is less than the inlet plate diameter.Be provided with electromagnetic switch valve in the described gas inlet pipe.
The utility model system adopts plane contact type air inlet face structure, regulates the switching of the one group of compact arranged round needle shape of circular arc small through hole, and then realizes the fine adjustment of combustion gas air inflow.It is a confined space that the rubber seal that is contained in the regulating shaft middle and upper part will make from sealing circle to outer casing bottom, prevents to fire back gas leakage.Owing between cover and regulating shaft, spring is housed, even when using for a long time that generation is worn and torn between semilune adjustable plate and inlet plate contact-making surface, also can make both keep tight contact, for the accurate adjusting of combustion gas air inflow provides reliable assurance.The utility model is suitable for using on the gas appliances such as gas heater, gas furnace.
Compared with prior art, the utlity model has following advantage:
1, simple in structure, easy for installation, safe in utilization.
2, it is very accurate that combustion gas air inflow is regulated, thereby make the water outlet water temperature precisely controlled, the water outlet water temperature from exceed into the water water temperature more than 2 ℃ with regard to practicable accurate control.
3, good seal performance can prevent to fire back gas leakage.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the front view of semilune adjustable plate shown in Figure 1.
By following embodiment the utility model is further elaborated.
Referring to Fig. 1, shown in Figure 2, the gas regulator that embodiment gas heater of the utility model is used, it is made up of cover 1, spring 2, rubber seal 3, regulating shaft 4, shell 5, combustion gas escape pipe 6, gas inlet pipe 7, electromagnetic switch valve 8, inlet plate 9, round needle shape small through hole 10, semilune adjustable plate 11.Described regulating shaft 4 bottoms are semilune adjustable plate 11, and regulating shaft 4 central slot are equipped with rubber seal 3, and spring 2 and cover 1 are sleeved on regulating shaft 4 tops successively, form the regulating shaft assembly.Shell 5 bottoms are connected to gas inlet pipe 7, and this pipe connects with shell 5 internal cavities, and electromagnetic switch valve 8 is housed in gas inlet pipe 7, carry out switching control to cooperate the complete machine controlling organization that combustion gas is entered pipeline.Shell 5 middle parts are connected to combustion gas escape pipe 6, and air feed is carried out in the combustion chamber of water heater, and escape pipe 6 connects with shell 5 internal cavities.Air inlet pipe 7 and shell 5 mutually the top at the place of passing through and escape pipe 6 and shell 5 mutually the place of passing through bottom between closely be fixed with inlet plate 9 on the inner chamber proper level position, this inlet plate 9 is less than being drilled with one group of mutual disconnected aperture 10 on the periphery of semicircle continuously, it is round needle shape small through hole, present embodiment is to be drilled with row's equal diameter small through hole 10 continuously at inlet plate 9 radiuses such as grade and on less than the camber line of semicircle, for other embodiment, also can adopt one group of anisodiametric small through hole, it also is very accurate that its air inflow is regulated.The regulating shaft assembly is packed in shell 5 inner chambers, and it is fastened on the shell 5 with screw, at this moment, semilune adjustable plate 11 and inlet plate 9 Elastic Contact, the diameter of adjustable plate 11 is less than inlet plate 9 diameters, but, make semilune adjustable plate 11 can cover all small through hole 10 fully greater than these group small through hole 10 formed camber line diameters, can freely freely rotate again along ground.Because the elastic force effect of spring 2 even long-term work causes the wearing and tearing of adjustable plate 11 and inlet plate 9, also can obtain compensation, guarantees that both are in tight contact forever.Rotate the one group of small through hole 10 that makes on the adjustable plate 11 with manual or driven by motor regulating shaft 4 and just can accurately be regulated the combustion gas gas output from covering in fully to open gradually.
