Description

The gas-liquid distributing valve of vacuum filter

(1) technical field: the utility model relates to a kind of gas-liquid distributing valve, especially a kind of gas-liquid distributing valve of vacuum filter.

(2) background technology: the utility model belongs to the gas-liquid distributor of vacuum filter.General vacuum dewatering apparatus is widely used in metallurgy, industries such as mine, food and medication chemistry, in operation, existing gas-liquid distributor structure more complicated, as shown in Figure 7, the gas-liquid distributor has only a sealing ring promptly to distribute quiet circle 4, seal 9,10 etc. is arranged in addition, complex structure, sealing is poor, and service life is also short.As shown in Figure 9, the work allocation district of the quiet circle 4 of the distribution of prior art is unreasonable, its b=1.2a, and through hole 401 is not circular, is difficult to processing.As shown in Figure 8, the center of circle of the through hole 502,503 on the fixed mount 5 and the center of fixed mount 5 not point-blank but are not in staggered distribution, and occur the leak of liquid phenomenon easily.

(3) summary of the invention: the purpose of this utility model is to provide a kind of simple in structure and long service life, the gas-liquid distributor of the vacuum filter that the workspace is distributed rationally, processing is simple, easy to maintenance.

The purpose of this utility model can reach by following measure: the gas-liquid distributing valve of vacuum filter, by the quiet circle 4 of the distribution that is installed in rotating shaft 1 end, distribute quiet circle 4 fixed mounts 5, and the set bolt 7 on the fixed mount 5, hold-down nut 6 and spring 8 compositions, it is characterized in that: between rotating shaft 1 end and the quiet circle 4 of distribution, be provided with and distribute moving-coil 3.Distribute moving-coil 3 to be fixed on the moving-coil fixed mount 2, moving-coil fixed mount 2 is fixed on the end of rotating shaft 1 by bolt 13.Distribute to center on the moving-coil 3 around the centre bore 11,12 apertures 12 that evenly distribute, corresponding with 12 limbers in the rotating shaft 1.Distribute the through hole 401 on the quiet circle 4 to be circle, the arc length distribution of circular arc through hole 402,403 is that the b radian doubles a radian, and the c radian is slightly larger than the e radian, and the d radian is 5 degree, and the f radian is slightly larger than a radian.Two sections circular arc deep trouths, 504,505 arc length distribution by on the one side of distributing quiet circle 4 of fixed mount 5 are that the b radian doubles a radian, and the c radian is slightly larger than the e radian, and the d radian is 5 degree, and the f radian is slightly larger than a radian.The center of circle of the through hole 502,503 on the fixed mount 5 and the center of fixed mount 5 point-blank, and lower through-hole 503 is a bit larger tham through hole 502.

Compared with the prior art the utility model has following good effect: owing to reduced the sealing device 9,10 in the prior art, make to simplify the structure maintenance and easy to maintenance; Distribute moving-coil 3 owing to increased by one, and adopt ceramic minute surface sealing, long service life; Owing to changed the position of through

hole

502 and 503, the center of circle that makes through hole 502,503 and the center of fixed mount 5 so discharge opeing is more smooth and easy, are difficult for leakage point-blank.Because the processing district is distributed rationally, the b radian doubles a radian, and the c radian is slightly larger than the e radian, and the d radian is 5 degree, the bigger and a radian of f radian, so processing is simple, and the efficient height; Changed fixed form, reasonable in design, stability improves.
