Abstract
The invention discloses a pulse butterfly valve for combustion control. The pulse butterfly valve comprises a shell, an electromagnetic head arranged at the end of the shell, a gear rack transmission device which is arranged in the middle of the shell and is in transmission connection with the electromagnetic head, and a valve body arranged below the shell, wherein a valve rod which is in transmission connection with the gear rack transmission device is arranged in the valve body; the lower end of the valve rod is provided with a valve plate device; an electromagnetic return spring is connected between the gear rack transmission device and the electromagnetic head; and a valve body return spring is connected between the upper end of the valve rod and the gear rack transmission device. The pulse butterfly valve for the combustion control combines the advantages of an electromagnetic valve and a butterfly valve, has a simple and reliable structure, and can resist the temperature of 550 DEG C.
Description
Technical field
The present invention relates to the control gear of a kind of gas piping flow size, particularly a kind of pulse butterfly valve of the control that is used to burn.
Background technique
Now general boiler, metallurgy, the solenoid valve in the burning control of industries such as machinery of being applied to; Do not have auto-reset function, after the Electrical heads outage, valve body can not reset; And general butterfly valve does not have automatic executing function, like this, causes the control reaction velocity of valve body slow; And, use the control poor effect.
Summary of the invention
In order to overcome the deficiency of existing technology, the object of the present invention is to provide a kind of advantage that automatically performs that had not only had a solenoid valve, but also have butterfly valve automatically reset advantage be used to burn the pulse butterfly valve of control.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of pulse butterfly valve of the control that is used to burn; Comprise housing, be located at shell end Electrical heads, be located in the middle of the housing and the rack and pinion drive that is in transmission connection with Electrical heads, the valve body of being located at the housing below; Be provided with the valve rod that is in transmission connection with rack and pinion drive in the valve body; The underpart of valve rod is provided with the valve plate device; Be connected with the electromagnetism Returnning spring between said rack and pinion drive and the Electrical heads, be connected with the valve body Returnning spring between the upper end portion of valve rod and the rack and pinion drive.
Technique scheme also can have following improvement project: the other end of said housing is provided with the dominant bit of the aperture size that is used for the control valve panel assembly and the limit stoper of minimum bit, and limit stoper is connected in the end of rack and pinion drive; The outside of said housing is provided with outside valve position indicating device, and outside valve position indicating device is connected on the rack and pinion drive.
The invention has the beneficial effects as follows: the advantage that has combined solenoid valve and two kinds of devices of butterfly valve; And two kinds of advantages are combined, its power resources are in solenoid valve, and its final executive component is the butterfly valve part that electromagnetism Returnning spring, valve body, valve rod are formed; So have the characteristics of butterfly valve; Simple in structure, reliable, can heatproof to 550 degree.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the present invention is further specified.
Fig. 1 is a structure sectional view of the present invention.
Embodiment
With reference to Fig. 1; The present invention is a kind of be used to the to burn pulse butterfly valve of control; Comprise housing 5, be located at housing 5 ends Electrical heads 1, be located in the middle of the housing 5 and the rack and pinion drive 2 that is in transmission connection with Electrical heads 1, the valve body 7 of being located at housing 5 belows; Be provided with the valve rod 8 that is in transmission connection with rack and pinion drive 2 in the valve body 7; The underpart of valve rod 8 is provided with valve plate device 10, is connected with electromagnetism Returnning spring 6 between said rack and pinion drive 2 and the Electrical heads 1, is connected with valve body Returnning spring 9 between the upper end portion of valve rod 8 and the rack and pinion drive 2.
Technique scheme has following improvement project: the other end of said housing 5 is provided with the dominant bit of the aperture size that is used for control valve panel assembly 10 and the limit stoper 3 of minimum bit, and limit stoper 3 is connected in the end of rack and pinion drive 2; The outside of said housing 5 is provided with outside valve position indicating device 4, and outside valve position indicating device 4 is connected on the rack and pinion drive 2.
Working principle of the present invention: McK electromagnetic pulse butterfly valve of the present invention gains impetus through Electrical heads 1; Executive component is a valve plate device 10; Middle through rack and pinion drive 2 to-and-fro motion of Electrical heads 1 is converted into the rotation of valve rod 8, valve rod 8 drives valve plate devices 10 and carries out switch motion.Limit stoper 3 can carry out spacing to the aperture size of valve plate device 10, and outside valve position indicating device 4 plays the effect of real-time indicating valve Board position.
The present invention can pass through its simple adjusting, thereby reach the dominant bit of valve body aperture and the qualification of minimum bit through the design of limit stoper 3.Outside valve position indicating device 4 is set, can shows the size and the physical location of valve plate device 10 apertures easily and intuitively.Electromagnetism Returnning spring 6 and valve body Returnning spring 9 utilize this torsion that when Electrical heads is switched on, stores that valve plate device 10 is resetted, thereby reach closing state under the situation of Electrical heads outage.
The present invention is mainly used in boiler, and metallurgy in the burning control of industries such as machinery, generally is installed in the size that is used for controlling combustion air volume on the combustion air pipeline.The combustion air temperature is generally between-30 degree ~ 550 degree.
In addition, the present invention is not limited to above-mentioned mode of execution, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
