Description
Technical field
The utility model belongs to universal machine valve technology field, especially relates to a kind of ceramic ball valve very high to switch frequency requirement.
Background technique
At present, in the position such as silica flour conveying of silicon chemical industry, valve switch frequency is very high, 50S switch once, one month the most nearly 60,000 8 thousand times; Its medium is silica flour; Normal temperature, normal pressure.Conventional ceramic ball valve will occur at valve rod place leaking for have more than is needed several days, and high-frequency valve rod rotates the wearing and tearing of filler very large, and conventional filling-material structure is difficult to meet high frequency requirements, makes this position be difficult to realize automation, limits the production scale of enterprise.
Summary of the invention
The purpose of this utility model is to improve the deficiencies in the prior art and provides that a kind of applicable switching frequency demand is high, sealing is reliable, moment of torsion slim and graceful, the high frequency ball valve of long service life.
The purpose of this utility model realizes like this, a kind of high frequency ball valve, the ball core be mounted in valve body connects valve rod, valve body is provided with upper mounting plate, graphite packing is provided with between upper mounting plate and valve rod, packing press ring and hold-down grid are installed above graphite packing, metal flange and ceramic flange liner is respectively equipped with in the both sides of valve body, valve seat is arranged on valve body, inside metal flange and ceramic flange liner, valve body liner is installed between valve seat and valve body, valve seat and valve body liner, ceramic flange liner connection part is provided with seal ring, metal flange and valve base chamber are provided with leaf spring, be characterized in that the shaft shoulder of valve rod is stuck in the lower end surface of upper mounting plate, lining is provided with between valve body and valve rod, O RunddichtringO is provided with between valve rod and lining, saddle packing is arranged on below lining.
In order to realize the purpose of this utility model further, can be that screw rod is fixed in upper mounting plate, the nut coordinated with screw rod compresses hold-down grid, is equipped with disc spring under nut.
In order to realize the purpose of this utility model further, can be slot on metal upper mounting plate, hold-down grid, packing press ring be arranged in groove.
In order to realize the purpose of this utility model further, can be provided with thrust washer between the shaft shoulder and upper mounting plate of valve rod.
In order to realize the purpose of this utility model further, can be provided with polytetrafluoro pad at metal flange and valve body liner, valve body connecting part.
In order to realize the purpose of this utility model further, can be on valve rod, be provided with the oil groove be communicated with O RunddichtringO mounting groove, valve body be provided with the oil hole be communicated with oil groove.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model increases lining by between valve rod and valve body, lining is best with cast copper alloy, lining and valve body, to seal with O type circle between lining and valve rod, sealing is effectively lasting, very little to the friction torque of valve rod; Graphite establishment filler is installed in upper mounting plate, graphite establishment filler can be supplied to the good positioning action of valve rod, ensures the position degree of valve rod, makes valve rod tilt and to produce friction torque with other metalworks, ensure that O RunddichtringO circumferentially uniform force simultaneously, reduce the rate of wear; Screw rod is fixed in upper mounting plate, and the nut coordinated with screw rod compresses hold-down grid, is equipped with disc spring under nut, and disc spring can provide automatic pretightening force, even if after filler wearing and tearing, still can keep compressing effect, to keep the position degree of valve rod; Hold-down grid, packing press ring are arranged in the groove of upper mounting plate, to reduce valve boundary dimension, reduce the possibility that interfering with other system appears in erecting bed; The thrust washer of PTFE material is provided with between the shaft shoulder and upper mounting plate of valve rod, during valve pressure-bearing, valve rod produces positive pressure to upper mounting plate, and then generation friction torque, here use the extremely low and corrosion-resistant extremely strong PTFE material of friction factor to use as thrust bearing, effectively can prevent " occlusion " of valve rod and upper mounting plate; The polytetrafluoro pad that metal flange and valve body liner, valve body connecting part are provided with, not only can ensure existing sealability, reduce friction torque simultaneously; Valve rod is provided with the oil groove be communicated with O RunddichtringO mounting groove, valve body is provided with the oil hole be communicated with oil groove, neither affect the performance of O RunddichtringO, can use by storing lubricating grease again, to improve the life-span of O RunddichtringO further, the external lubricating cup of oil hole, by cycle grease up, to improve the life-span of O RunddichtringO further.
The utility model can meet the effective sealing under long-time high frequency Switching Condition, can reduce again the friction torque of valve rod, reduces the torque demand to final controlling element.Still can the valve of effective sealing lastingly under high-frequency Switching Condition.Make enterprise can set up automatic production chain, greatly improve the economical production scale of enterprise, obtain benefit.
