Description

Millstone type mass transport ceramic valve
Technical field:
The valve in switch, pipeline and grey storehouse on the utility model and the material bin pump is relevant, especially relevant with pneumatic rotational circle moushroom valve.
Background technique:
Existing pneumatic rotational circle moushroom valve comprises the cylinder of being located on the support, and valve body and be located at one group of valve seat of its both sides is provided with the flashboard that swing cooperates between the valve seat.The flashboard side of valve seat endoporus is provided with seal ring, the seal ring formation sealing pair that matches with flashboard, cylinder flexibly connects by connecting shaft and crank one end, the crank the other end and running shaft flexibly connect, running shaft is fixedlyed connected with flashboard, is driven the unlatching and the sealing of two-sided flashboard realization and valve base sealing ring by running shaft.Running shaft is fixedly mounted on two valve bodies, and is parallel with flashboard.The valve mechanism complexity, between flashboard and the valve base sealing ring, wear and leakage is easy to deposit material in the valve chamber easily, removes inconvenience.
The content of model utility:
The purpose of this utility model provides a kind of simple in structure, and sealing is reliable, the millstone type mass transport ceramic valve of long service life.
The utility model is achieved in that
The utility model millstone type mass transport ceramic valve, valve gap 8 is connected with support 1, support 1 is hinged with an end of cylinder 2, the piston rod that the other end of cylinder 2 exposes is hinged by the end of coupling yoke 3 with connecting rod 4, one end of the other end of connecting rod 4 and rotating shaft 6 is connected, the other end of rotating shaft 6 and pivoted arm 15 1 ends are connected, rotating shaft 6 is supported on the valve body 5, the other end of pivoted arm 15 is connected with flashboard 12, flashboard 12 is tightly connected with valve seat 13, and valve seat 13 and flashboard 12 respectively have a sealing surface, and valve seat 13 is connected with valve gap 8, in the rotating shaft between valve gap 8 and the connecting rod 4 spring 11 is arranged, pivoted arm 15 has centering ball 14 with joint, flashboard 12 center.
The fluted projection Spielpassung with flashboard 12 centers in the end of pivoted arm 15, the interior steel balls 14 of fluted and pivoted arm 15 end recesses cooperate on the projection.
Flashboard 12 has ceramic plate and steel flashboard frame to be connected, and the groove on the projection at steel flashboard frame center cooperates with steel ball 14, and spring 11 is for being enclosed within the pressure spring in the rotating shaft.
The utility model is simple in structure, and valve body is difficult for dust stratification, and ceramic valve seat is arranged on the valve gap, and ceramic flashboard can not offset the active force of pressure spring by the steel ball self-alignment.Pressure spring makes the sealing surface of ceramic flashboard and ceramic valve seat remain enough seal pressures, has well solved wearing and tearing, dust stratification and etching problem, and the utility model switch is flexible, and is easy to operate, long service life.
Description of drawings:
Fig. 1 is the utility model structural drawing.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
Valve body 5 is hemisphere or dish, and its cambered surface is downward, and valve gap 8 is that the plane is connected with valve body 5 upper ends.
Rotating shaft 6 has filler 7 and gland 9 in the via hole of valve gap 8, adjust gland by bolt and produce sealing force, and thrust bearing 10 is housed on the gland.
Valve body 5 is designed to hemisphere or dish, and dust is difficult to accumulate in the valve body in the conveying.Valve gap 8 passage places are provided with ceramic valve seat 13, but the center Point of Strength of pottery flashboard 12 is provided with steel ball 14, steel ball self-alignment, and flashboard and sealing surface of seat are fitted tightly, and under the effect of pressure spring 11, produce the seal pressure of flashboard and valve seat, reach the purpose of not leaking after closing.Flashboard and valve seat are stupalith, can effectively prevent dielectric corrosion and erosive wear, thereby improve working life.
Flashboard 12 is circular, and it moves to rotatablely moving.The switch motion of flashboard 12 is achieved like this: a support 1 is fixed on valve gap 8 tops, and cylinder 2 is hinged on the support, and cylinder is by coupling yoke 3 and connecting rod 4, and drive rotating shaft 6 and the pivoted arm 15 that is connected make flashboard carry out open and close and rotatablely move.Rotating shaft 6 is positioned on the valve body boss, and rotating shaft is provided with filler 7 at the via hole of valve gap, presses filler with filler gland 9, prevents that fed sheet of a media from leaking outside.Thrust bearing 10 is housed on the filler gland, the sliding friction of rotating shaft is converted into rolling friction, the switch moment when having reduced operation.
