Abstract
The utility model relates to a ball valve. One end of a valve rod is fixedly connected with a valve core of a valve body on which a valve cap is arranged, and one end of a transmission rod is extended out of the valve cap. The utility model is characterized in that an outer magnetic ring component is arranged in the valve cap and is linked with the transmission rod, and an inner magnetic ring component is sheathed in the outer magnetic ring component; the inner and the outer magnetic ring components are sealed and separated by a sealing cover, and the inner magnetic ring component is linked with the valve rod. The utility model overcomes the defect that the ordinary ball valve has serious leakage and has the advantages of simple structure, zero leakage, no pollution, labor saving for rotation, negative pressure operation without external gas entering the ball valve, and obvious effect on processing some special liquid or liquid, and meanwhile, the utility model has no friction torque between the valve rod and fed material.
Description
The utility model relates to a kind of ball valve.
Modern industrial technology has proposed more cocksure requirement to valve, present operating valve, particularly the leakage of ball valve valve rod is very common, leak the pressure loss that not only causes system, the waste of fluid, for the leakage of corrosivity, explosion hazard, toxic fluid can bringing on a disaster property consequence.Therefore, how thoroughly solving the leakage problem of valve, is a great problem in present this field.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby a kind of ball valve of simple in structure, positive confinement is provided.
Valve body, valve rod, spool, drive link and the valve gap of comprising of the present utility model, one end of valve rod and the spool Joint in the valve body, the other end and the interlock of internal magnetic ring assembly, valve gap is arranged on the valve body, be provided with the outer magnetic ring assembly in the valve gap, outer magnetic ring assembly and drive link interlock, an end of drive link stretches out outside the valve gap, the internal magnetic ring assembly is sleeved in the outer magnetic ring assembly, between the two by the sealing cover seal isolation.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises valve body 2, valve rod 3, spool 1, drive link 7 and valve gap 8, spool 1 in the affixed valve body 2 of one end of valve rod 3, the other end and 4 interlocks of internal magnetic ring assembly, valve gap 8 is arranged on the valve body 2, be provided with outer magnetic ring assembly 5 in the valve gap 8, outer magnetic ring assembly 5 and drive link 7 interlocks, an end of drive link 7 stretches out outside the valve gap 8, and internal magnetic ring assembly 4 is sleeved in the outer magnetic ring assembly 5, by sealing cover 6 seal isolation, make 2 of sealing cover 6 and valve bodies constitute confined space between the two.Under user mode, the inner magnetic ring component 5 of the rotation of spool 1 drives, and outer magnetic ring assembly 5 passes through drive link 7 transmissions by manpower or Electric actuator.
The utility model is by above-mentioned concrete structure, make ball valve long-term safety reliable operation under the state of no stuffing box, and zero leakage is pollution-free, to handling rare, expensive, hypertoxic, dangerous liquid or gas obvious benefit is arranged, simultaneously, there is not valve rod in the utility model and adds friction torque between material, rotates laborsaving; Negative-pressure operation does not have ambient atmos and enters.
