Unum eccentrici papilio valvae
Ut solvere extrusionem forsit inter discus et valvae sedem in concentricis papilio valvae, unum eccentricam papilionem valvae produci. Dispergere et reducere nimia extrusionem superiorum et inferioris fines papilio laminam et valvae sedem. Tamen, ex uno eccentrici structuram, et rasum phaenomenon inter discus et valvae sedem non evanescet in tota foramen et claudendo processus of valvae, et application range est similis, quod de concentricis papilio et application range est simile quod de concentricis papilio et application range est simile quod de valvae papilio, ita non est tantum.
Duplex eccentricis papilio valvae
De ex uno eccentrici papilio valvae, est Duplex eccentrici papilio valvae quae est late ad praesens. Et structural pluma est quod in medio Center de valvae derivantur deviat a centro discus et centrum corporis. The effect of double eccentricity enables the disc to break away from the valve seat immediately after the valve is opened, which greatly eliminates unnecessary excessive extrusion and scratching between the disc and the valve seat, reduces the opening resistance, reduces wear, and improves the Seat life. Radping valde reducitur et simulDuplex eccentrici papilio valvae Potest etiam utor a metallum valvae sedem, quod amplio applicationem de papilio valvae in altum temperatus agro. However, because its sealing principle is a positional sealing structure, that is, the sealing surface of the disc and the valve seat is in line contact, and the elastic deformation caused by the disc extrusion of the valve seat produces a sealing effect, so it has high requirements for the closing position (especially metal Valve seat), low pressure bearing capacity, which is why traditionally people think that butterfly valves are not resistant to high pressure and have large leakage.
Triplex eccentrici papilio valvae
Urstandam altum temperatus, durum sigillum esse solebat, sed moles lacus est magna; Ut nulla lacus, a mollis sigillum debet esse, sed non repugnant ad altum temperatus. Ut vincere contradictionem duplici eccentricis papilio valvae, papilio valvae erat eccentrici tertio. Et structural pluma est quod dum duplex eccentricam valvae derivantur est eccentrici, conica axis discus signa superficies inclinatur ad cylindri axis corporis, id est dicere, post tertium, quod ad sectionem non mutare. Tum est circulus, sed ellipsis, et figura ex eius signantes superficiem quoque asymmetrical, una parte inclinatur ad centrum linea corporis et alter parallelae centrum linea corporis. The characteristic of this third eccentricity is that the sealing structure is fundamentally changed, it is no longer a position seal, but a torsion seal, that is, it does not rely on the elastic deformation of the valve seat, but completely relies on the contact surface pressure of the valve seat to achieve the sealing effect , Therefore, the problem of zero leakage of the metal valve seat is solved in one fell swoop, and because the contact surface pressure is proportional to the Medium pressura, princeps pressura et altum temperatus resistentia est etiam facile solvitur.
