Description
Technical field
The utility model relates to gas water-heater accessory field, a kind of gas distribution device that is used for gas water-heater of saying so more specifically.
Technical background
At present, the burning dispensing device that general airtight exhausting formula burner is adopted on the water heater has only a blast tube.The branch device of air of this structure because have only a passage, so all burner assembly all can be worked, is promptly all burning when work.And but the heat load scope of the smooth combustion of monolithic burner is narrow.So during gas water heater working, its minimum thermal load is these several monolithic burner minimum thermal load sums just.All the monolithic burners are with the minimum thermal load operation, and its total heat duties is also just quite big, and also less stable of burner operation this moment, and it is poor wind loading rating to occur; Easily tempering; Take off situations such as fire.And total heat duties is big, obtain low temperature and must be transferred to maximum could the use to water flow.Such water heater is from hommization, and all there is deficiency aspects such as Economy, and current energy-saving and cost-reducing be a main trend, to economize the gas water-saving great for environment protection significance if can reach same effect.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of stability that can improve gas water-heater in underrun is provided, and reduces the gas distribution device that is used for gas water-heater of its minimum thermal load in other words conj.or perhaps.
The purpose of this utility model is achieved through the following technical solutions.
The utility model comprises gas valve main body, cylindrical two section valve cores, cylindrical two section valve core is installed on the gas valve main body, on the valve body of cylindrical two section valve core one sides, be provided with two blast tubes four, five of isolating mutually, be respectively equipped with the through hole that can be communicated with on the blast tube four, five with the monolithic burner; On the valve body of cylindrical two section valve core opposite sides, be provided with continuous two blast tubes two, three, and have valve seat that the self-priming valve that may command blast tube three is opened and closed is installed on the blast tube three, be provided with blast tube one at cylindrical two section valve core one ends, passage one is provided with the through hole that can be communicated with blast tube five, two respectively, and cylindrical two section valve core bodies are provided with the groove that is communicated with blast tube three, four.
In order to guarantee that combustion gas can not leak, the both sides up and down of blast tube are respectively arranged with O-ring seal on cylindrical two section valve core bodies.
For the ease of regulating the flow size of combustion gas, thereby the regulation range of control monolithic burner heat load, above-mentioned cylindrical two section valve cores are movably arranged on the gas valve main body, make cylindrical two section valve core do radially rotation, and the through hole that is communicated with blast tube five, two on the blast tube one of cylindrical two section valve cores is two groups of size sets of vias in the several angle scope.Cylindrical two section valve core radially rotates to diverse location, and blast tube one can be communicated with blast tube five, two by the through hole that varies in size, and is combined into different combustion gas by sectional area, realizes regulating the flow size of combustion gas.
Above-mentioned two groups of size sets of vias, every group of through hole is made up of two different through holes of pore size at least.
The utility model has following substantive distinguishing features and progress with respect to prior art:
Valve body is provided with two blast tubes four, five of isolating mutually, make the user can control the quantity of the monolithic burner that participates in burning as the case may be, the flow sizes that while two groups of sizes sets of vias can further realize regulating combustion gas, therefore, lowest temperature rise of the present utility model can be done very lowly, effectively solve the too boiling hot problem of water in summer, save combustion gas; And obtaining of low temperature need be with excessive water flow, so save water resources.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1, the utility model comprises gas valve main body 2, cylindrical two section valve cores 1 and self-priming valve 3, and cylindrical two section valve cores 1 and self-priming valve 3 are assemblied on two section valve bodies 2 by technical requirements, notices that the relevant position installs O-ring seal 4 additional.On the valve body of cylindrical two section valve core 1 one sides, be provided with two blast tube 4 11, blast tubes 58 of isolating mutually, be respectively equipped with the through hole 13 that can be communicated with on blast tube 4 11, the blast tube 58 with the monolithic burner, on the valve body of cylindrical two section valve core 1 opposite sides, be provided with continuous two blast tubes 29, blast tube 3 10, and have valve seat that the self-priming valve 3 that may command blast tube 3 10 is opened and closed is installed on the blast tube 3 10, be processed with blast tube 1 and big or small sets of vias 6 and 7 on the end of cylindrical two section valve cores 1.Size sets of vias 6 is made up of two different through holes of pore size respectively with 7.Add and will note its position man-hour, when the two section of slewing circle cylindricality valve cores 1, during the blast tube 58 corresponding cooperations of its large through-hole of 6 groups and two sections valve bodies 2,7 groups large through-hole also will with the blast tube 29 corresponding cooperations of two sections valve bodies 2.During the blast tube 58 corresponding cooperations of its small through hole of 6 groups and two section valve bodies 2 in like manner, 7 groups small through hole also will with the blast tube 29 corresponding cooperations of two sections valve bodies 2.Cylindrical two section valve core body 1 is provided with the groove 12 with blast tube 3 10, blast tube 4 11 UNICOMs.
Combustion gas is circulated in this pair section gas distribution device two states: as shown in Figure 1, combustion gas this moment enters cylindrical two section valve core 1 blast tube 1 and enters two section valve bodies 2 through big or small sets of vias 7 again.And because self-priming valve 3 has been blocked blast tube 3 10, so do not have combustion gas in the blast tube 4 11.And the combustion gas that enters the blast tube 58 of two section valve bodies 2 by big or small sets of vias 6, we can great according to actual needs minimum thermal load to determine the diameter of small through hole in the big or small sets of vias 6 its flow size.This kind of Fig. 1 state, this moment, we also can regulate the gas flow that flows in the blast tube 58 by the two section of slewing circle cylindricality radially valve cores 1.Use gas water-heater when common this state is used for summer, this state can be transferred to gas water-heater the minimum thermal load.
Equally, as shown in Figure 2, combustion gas this moment enters cylindrical two section valve core 1 blast tube 1 and enters two section valve bodies 2 again, combustion gas is respectively by big or small sets of vias 6,7, enter blast tube 58 and blast tube 29, because self-priming valve 3 is opened, combustion gas can enter blast tube 4 11 by blast tube 3 10.So as Fig. 2 state, we can regulate by the two section of slewing circle cylindricality valve cores 1 radially and flow into the interior gas flow of blast tube 4 11 and blast tube 58 this moment, gas water-heater can be transferred to maximum heating load in this state.
