Abstract
The utility model relates to a three-way reversal valve, which comprises a casing body (1), fuel gas, an air port (2), exhaust air port (3), a gas burner port (4), a movable plate (5), a valve shaft (6) which is connected with the movable plate and a cylinder (7). When the valve shaft (6) is controlled by the cylinder (7) to lead the movable plate (5) to be tightly contacted with a first contact plate body, the fuel gas, the air port (2) and the gas burner port (4) are communicated with each other; when the valve shaft (6) is controlled by the cylinder (7) to lead the movable plate (5) to be tightly contacted with a second contact plate body, the exhaust air port (3) is communicated with the gas burner port (4). The utility model has the advantages of high temperature resistance, good seal performance and flexible action; after the reciprocation time of a cylinder is regulated, the flow direction of gas can be continuously changed back and forth on schedule in operations.
Description
Technical field
The utility model relates to a kind of three-way diverter valve, relates in particular to a kind of three-way diverter valve that is applied on the industrial combustion furnace control burner.
Background technique
In the industrial combustion furnace system, in order to control the flow direction of combustion gas, general employing selector valve plays the effect of opening and closing combustion gas.
Valve is to be installed in the combustion furnace furnace gas system.On the one hand, its Environmental Conditions is to carry out work in the gas of higher temperature, and main action is to make fuel gas, air enter the stove burner and waste gas is got rid of, the two alternately circulation, per 30 seconds gas exchange once, so the action of valve is more frequent; On the other hand, the temperature of fuel gas and waste gas is higher, and valve needs long-term the use under temperature is 200 ℃ situation, and sometimes, the transient temperature of short time is 300 ℃; The 3rd, gas has the oxidation corrosive action slightly, and is to work under 0.05Mpa pressure, and valve needs sealing, and it allows leakage rate to need less than 1%.
At present, the three-way diverter valve that can be fit to these three kinds of situations does not fully also have, and is that pendulum needs a problem solving in face of the science and technology personnel.
Summary of the invention
The utility model technical issues that need to address have provided a kind of three-way diverter valve, are intended to address the above problem.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: housing, fuel gas, air scoop, exhaust outlet, fuel burner nozzle mouth; Also comprise a mobile plate, a valve shaft that is connected with mobile plate, a cylinder; Connect airtight when touching when the cylinder control valve axle contacts plate body with mobile plate with first of exhaust outlet, fuel gas, air scoop communicate with the fuel burner nozzle mouth; Connect airtight when touching when the cylinder control valve axle contacts plate body with mobile plate with second of fuel gas, air scoop, exhaust outlet communicates with the fuel burner nozzle mouth;
Respectively settle a seal ring at described mobile plate upper and lower end.
Compared with prior art, the beneficial effects of the utility model are: high temperature resistant, and good seal performance, flexible movements during motion; After the reciprocal time of adjusting cylinder, just can constantly exchange the flow direction of gas in the operation back and forth on time.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: housing 1, fuel gas, air scoop 2, exhaust outlet 3, fuel burner nozzle mouth 4; Also comprise 6, one cylinders 7 of 5, one valve shafts that are connected with mobile plate of a mobile plate; Connect airtight when touching when cylinder 7 control valve shafts 6 contact plate body 31 with mobile plate 5 with first of exhaust outlet 3, fuel gas, air scoop 2 communicate with fuel burner nozzle mouth 4; Connect airtight when touching when cylinder 7 control valve shafts 6 contact plate body 32 with mobile plate 5 with second of fuel gas, air scoop 2, exhaust outlet 3 communicates with fuel burner nozzle mouth 4;
Respectively settle a seal ring 51 at described mobile plate 5 upper and lower ends;
The described first contact plate body 31 contacts plate body 32 and adopts hot and corrosion-resistant steel with second; Described seal ring 51 adopts fluorine rubber.
The utility model has three interfaces, one enters fuel gas and air, a exhaust port for the eliminating flue gas, and another is the interface that is connected with fuel burner nozzle, three interfaces are moved around once every 30 seconds by the mobile plate of centre, join so that connect burner end and gas port or relief opening.The reciprocating action of mobile plate by external cylinder as power, because fuel gas and waste gas are to have temperature and corrosivity, and may be mixed with micro-dust, make the tight sealing of mobile plate energy, elastic soft seal is adopted in design, but the gas that passes through is to have corrosivity and higher temperature is arranged, so seal ring is to adopt heat-resisting fluorine rubber, contact plate body and valve shaft etc. are the hot and corrosion-resistant steel manufacturings with 1Cr18Ni9Ti, for the ease of make and profile neatly, main housing of the present utility model, HT250 cast iron is adopted in design, beautiful shape, the structure of HT250 cast iron are pearlite matrix, can resist 300 ℃ temperature invasion and attack with pearlitic iron.
Couple together with each interface in bolt and the pipeline when the utility model is installed, between two flanges, seal as bedding and padding during connection with asbestos cardboard.
For the ease of maintenance, mobile plate and seal ring can be pulled down replacing and needn't dismantle down whole valve, method is in meeting burner mouth place in pipe-line system, circuit design person only needs pipeline is loaded onto in addition the short circuit head (length of short circuit head is decided according to the size of valve) of a 250-600 millimeters long, when maintenance, just only need shed short circuit head like this, just can carry out the loading and unloading of inner body and change, needn't pull down heavy whole valve.
Installation method of the present utility model can be level also can be vertical, the installation form that can take according to pipeline and deciding.
