Abstract
The utility model provides a rotating eccentric type four-way directional selecting valve, comprising a valve body, a baffle board, a valve shaft, a rotating valve board and an air powered actuator. The valve body is a structure of square casing with four air vents around, the valve shaft is fixed on one side of the rotating valve board, and two ends of the valve shaft are engaged with bearings and disposed away from the central line. The rotating valve board is of round shape and corresponds with a semi-circle through hole on the baffle board, and a sealing ring of O shape is inlaid on the outer edge of the rotating valve board. The utility model is novel in structure, reasonable in design, small in volume, flexible and convenient in movement and long in application life. The utility model can satisfy the requirements of distributed direction selecting. The valve shaft of the four-way directional selecting valve employs eccentric structure, resolving the leakage problem of the rotating space between the valve shaft and the baffle board. The rotating valve board is a round structure, enabling the installation of the O shaped sealing ring to be a possibility. The linear sealing form greatly increases the sealing effect and is convenient to change. The air powered actuator is connected with the valve body via a flange and is convenient to maintain and change.
Description
Technical field
The utility model belongs to the accessory of regenerative combustion system on the industrial furnace, is the reversing arrangement between cool air, the high-temperature flue gas, relates in particular to a kind of rotating eccentricity formula four-way change-over valve.
Background technique
The four-way change-over valve that present regenerative combustion system is adopted mainly contains three kinds, its structural feature is as follows: 1. drawing and pulling type four-way change-over valve: structure is the casing form, by the mobile plate knee-action in the casing, airtight or open each cavity to realize commutation, compress seal ring by mobile plate and realize sealing.Its problem is bulky, mainly is applicable to centralized commutation, can not adapt to dispersion and arrange flexibly, and slow motion.2. rotary drum-type four-way change-over valve: form is inside and outside two tubular constructions.Inner core is a rotary drum, and urceolus is a stationary magazine creel.Urceolus respectively with air, flue gas, and A, B two to being connected, drive inner core by pneumatic actuator and do 90 ° rotation and realize commutation function.Characteristics are that volume is little, but have leakage problem between the inner/outer tube.3. common rotary type four-way selector valve: structure is the small box body form, and inside is four independently stationary barrier and the swivel plates that axis drives.Doing back and forth by pneumatic actuator driven rotary plate, 90 ° rotation realizes commutation function.Characteristics are that volume is little, action is fast, can realize the requirement of distributing commutation.But the sealing of this selector valve is to realize by the Stamping Steel Ribbon that swivel plate is fixed on the dividing plate, and this face seal mode is not very tight; Rotate on center line owing to valve shaft in addition, thereby must leave the gap between valve shaft and the stationary barrier, this just makes reveals unavoidably.
Summary of the invention
The purpose of this utility model is to provide a kind of advantage that can have above-mentioned various selector valve, and good leak tightness, dead-tight heat storage type combustion are with rotating eccentricity formula four-way change-over valve.
The utility model is achieved in that this rotating eccentricity formula four-way change-over valve is made up of the dividing plate in valve body, the valve body, the rotary valve plate that is connected with valve shaft and pneumatic actuator, valve body is the square box structure, be provided with four air ports all around symmetrically, described valve shaft is connected a side of rotary valve plate, two ends are furnished with bearing, and the disalignment setting.
The rounded shape of rotary valve plate described in the utility model, consistent with the semi-circular through hole on the dividing plate; On the outer rim of described rotary valve plate, stud with the O RunddichtringO; Be connected by flange between described pneumatic actuator and the valve body.
The utility model novel structure, reasonable in design, volume is little, flexible movements are quick, and long service life can satisfy the requirement of distributing commutation; The valve shaft of this four-way change-over valve adopts the eccentric structure, and making between valve shaft and the dividing plate has not had to contact, thereby has solved the leakage problem that running clearance brought between valve shaft and the dividing plate; Rotary valve plate is a round structure, makes that the O RunddichtringO is installed becomes possibility, and this kind linear sealing form has improved sealing effect greatly, and changes simple and convenient; Be connected with form of flanges between pneumatic actuator and the valve body, be convenient to safeguard and change.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model rotating eccentricity formula four-way change-over valve.
Accompanying drawing 2 is the A-A view of accompanying drawing 1.
Accompanying drawing 3 is the enlarged view of accompanying drawing 2I part.
Embodiment
With reference to the accompanying drawings the utility model rotating eccentricity formula four-way change-over valve is further described.
Can see that from attached Fig. 1 and 2 the utility model rotating eccentricity formula four-way change-over valve mainly is made up of valve body 1, dividing plate 2, valve shaft 4, rotary valve plate 3 and pneumatic actuator 5.Valve body 1 is the square box structure, is provided with four air ports all around symmetrically.Four dividing plates 2 are arranged in the casing 1 symmetrically, have semi-circular through hole in the side that crosses.Valve shaft 4 is fixedly connected on a side of rotary valve plate 3, and two ends are furnished with bearing, the disalignment setting.Pneumatic actuator 5 is fixed on the valve body 1 by flange, links to each other with the valve shaft 4 of eccentric position by key.Rotary valve plate 3 rounded shapes, consistent with formed round through hole on two relative dividing plates 2.Linear sealing between rotary valve plate 3 and the dividing plate 2 is to realize by the O RunddichtringO 6 that is embedded on rotary valve plate 3 outer rims, sees also accompanying drawing 3.
Because valve shaft 4 is the eccentric structure, not on center line, the sectional area of the semi-circular through hole on two dividing plates 2 that cause sealing with rotary valve plate 3 common realization commutations varies in size, and is promptly bigger near half hole sectional area on the dividing plate 2 of valve shaft 4.Semi-circular through-hole side (being the top of accompanying drawing 2) that can sectional area is less in the use is used for the cool air that flows, the hot flue gas of the mobile expanded by heating of the semi-circular through-hole side that sectional area is bigger (being the below of accompanying drawing 2).Can make air-flow obtain best distribution like this, reduce the drag losses of fume side.
The working principle of the utility model rotating eccentricity formula four-way change-over valve is as follows: two air ports of rotating eccentricity formula four-way change-over valve are connected with induced draught fan with blower respectively, and other two air ports are connected with two burners of A, B respectively.In the work when rotary valve plate 3 is positioned at a side position (state as shown in Figure 2), cool air is blown to A side burner by four-way change-over valve, cool air enters the stove internal combustion after being heated by heat retainer, this moment, the furnace high-temperature flue gas was got rid of by induced draught fan through four-way change-over valve by B side burner, and high-temperature flue gas heats the heat retainer in the B side burner therebetween.When pneumatic actuator 5 drives valve shaft 4 with rotary valve plate 3 half-twists arrival opposite side position, cool air is then blown to B side burner by four-way change-over valve, cool air enters the stove internal combustion after being heated by the heat retainer in the B side burner, this moment, the furnace high-temperature flue gas was got rid of by induced draught fan through four-way change-over valve by A side burner, and high-temperature flue gas heats the heat retainer in the A side burner therebetween.Its work moves so repeatedly.
