Abstract
The utility model relates to an air valve for jig cover plates, which particularly belongs to components of a Batac jig for the coal preparation industry and comprises a valve body. The valve body comprises an air box, an air inlet chamber, an air exhaust chamber, an air inlet pipe and an air exhaust pipe. The air valve for the jig cover plates is characterized in that an air inlet is arranged between the air box and the air inlet chamber and provided with an inlet cover plate capable of leading the air box to be communicated with or isolated from the air inlet chamber, an air exhaust outlet is arranged between the air inlet chamber and the air exhaust chamber and provided with an air exhaust cover plate capable of leading the air inlet chamber to be communicated with or isolated from the air exhaust chamber, the air inlet cover plate and the air exhaust cover plate are respectively connected with a piston rod of a sliding cylinder, a cylinder body is fixed to the outer wall of the valve body, and the air inlet and the air exhaust outlet are respectively provided with a sealing ring in an elastic structure. The air valve for the jig cover plates has the advantages that when the cover plate and a valve port are closed, sealing is reliable without air leakage and cylinder collision, when the cover plate and the valve port are opened, the back of a jig has no cover plate pressure, and the air valve can be opened automatically by using the positive chamber pressure and is easy in maintenance and long in service life.
Description
Technical field
The utility model relates to a kind of jigging machine cover plate air-valve, specifically belongs to the coal separation industry and uses the batac jig assembly.
Background technology
At present, domestic and international employed jigging machine cover plate air-valve, complex structure has back pressure during work, often causes to hit cylinder phenomenon, maintenance capacity and strengthen, poor reliability, its cover plate for sealing face sealing property is relatively poor, easyly goes here and there, air leakage phenomena.
The utility model content
The utility model technical issues that need to address provide a kind of jigging machine cover plate air-valve, through its architecture advances, eliminate and are pressed, and improve reliability, and improve through its ring structure, improve the valve seal performance, avoid string, air leakage phenomena.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of jigging machine cover plate air-valve comprises valve body; Valve body comprises bellows, inlet plenum, exhaust chamber and air inlet and exhaust piper, and inlet plenum is communicated with air inlet and exhaust piper, between bellows and the inlet plenum air inlet is set; Between inlet plenum and the exhaust chamber exhaust outlet is set; The air inlet setting can make bellows be communicated with inlet plenum or isolated air inlet cover plate, and the exhaust cover plate that the exhaust outlet setting can make inlet plenum be communicated with exhaust chamber or completely cut off, said air inlet cover plate and exhaust cover plate are connected the piston rod of sliding cylinder respectively; The cylinder body of sliding cylinder is fixed on valve outer wall, and said air inlet and exhaust outlet are provided with the sealing ring of elastic construction.
The further improvement of the utility model is:
Said sealing ring section is L shaped structure.
Because the technological progress of having adopted technique scheme, the utility model to obtain is: the blind flange air-valve housing construction of the utility model is new reasonable, sealing is reliable; Do not go here and there, leak out; High efficiency is saved the energy, does not have and hits the cylinder phenomenon; Do not have back cover plate pressure when opening, positive constant pressure capable of using is opened automatically; Easy care, life-span are long; The elastic seal ring that the cover plate air-valve is adopted, sealing is high when making cover plate and valve port closed, and prolongs each moving component working life.
Description of drawings
Fig. 1 is a kind of jigging machine cover plate air-valve structural representation;
Fig. 2 is the structural representation of sealing ring among Fig. 1;
Wherein: 1, slide cylinder, 2, the air inlet cover plate, 3, sealing ring, 4, bellows, 5, air inlet and exhaust piper, 6, the exhaust cover plate, 7, valve body, 7-1, inlet plenum, 7-2, exhaust chamber, 8, valve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is explained further details:
Shown in Figure 1, the utility model comprises valve body 7, and valve body 7 comprises bellows 4, inlet plenum 7-1, exhaust chamber 7-2 and air inlet and exhaust piper 5; Inlet plenum 7-1 is communicated with air inlet and exhaust piper 5; Between bellows 4 and the inlet plenum 7-1 air inlet is set, between inlet plenum 7-1 and the exhaust chamber 7-2 exhaust outlet is set, the air inlet setting can make bellows 4 be communicated with inlet plenum 7-1 or isolated air inlet cover plate 2; The exhaust outlet setting can make inlet plenum 7-1 be communicated with exhaust chamber 7-2 or isolated exhaust cover plate 6; Said air inlet cover plate 2 is connected the piston rod of sliding cylinder 1 respectively with exhaust cover plate 6, and the cylinder body of sliding cylinder 1 is fixed on valve body 7 outer walls, and said air inlet and exhaust outlet are provided with the sealing ring 3 of elastic construction.
Shown in Figure 2, said sealing ring 3 sections are L shaped structure, also can be designed to o shape structure.
Outer low pressure wind gets into bellows 4, and producing pressure is the blast of Po, and air inlet this moment cover plate 2 lifts through sliding cylinder 1, and Po gets into air inlet and exhaust piper 5 through sealing ring 3, accomplishes the jigging machine intake process; Close air inlet cover plate 2 during the jigging machine air draft, open exhaust cover plate 6 and accomplish whole jigging inlet and outlet process.
Claims (2)
