Abstract
The utility model relates to a three-six-way switching valve, belonging to the valve class, comprising a rack shaft whose two ends are provided with valves. The rack shaft is arranged on a supporting seat in the inner cavity of the valve bodies; a gear shaft is erectly arranged on one side of the rack shaft, and a gear on the gear shaft is engaged with a rack on one side of the rack shaft; one end of the gear shaft is extended out of the valve bodies. The test proves that the utility model has the advantages of large flow capacity, good sealing property convenient and flexible switching, etc.; the pressure is greater, and the sealing property is better; simultaneously, the utility model has easy manufacture and assemblage, low cost and strong versatility, and is particularly suitable for process pipelines used for conveying lubricating oil in the petroleum industry, the chemical industry, the mine industry, the smelting industry, etc.
Description
The utility model relates to a kind of three or six direction changeover valves, belongs to valve type, is particularly suitable for industries such as oil, chemical industry, mine, smelting and carries dress usefulness in the lubricant oil flow process pipeline.
Three or six direction changeover valves of always using till today from the eighties, it is the structural type of cantilever steel ball type, operation practice by for many years exposes following drawback: (1) is because steel ball and steel bushing are line contacts rigidity and seal and cause flow little, be far from reaching that design standard, sealability are not good, machining accuracy is high, difficulty is big, especially large-diameter valve, more difficult sealing is sunk in the steel ball deadweight; (2) owing to the restriction of Steel Cantilever spherical structure, not only the big heaviness of volume, the expense of taking a lot of work are expected, the assembling difficulty, and handover operation is heavy not nimble.Described for these reasons switching valve has further improved necessity.
The purpose of this utility model be to provide a kind of simple in structure, manufacturing is easy, little heavy easily light, low, the withstand voltage height of good seal performance of cost of volume, switches light and flexible, three or six direction changeover valves that flow is big.
The purpose of this utility model realizes by the following technical solutions, it comprises valve body, the rack shaft that two ends are provided with valve places on the supporting base of body cavity, gear shaft uprightly places a side of rack shaft, the tooth bar of a side is meshed on the wheel and rack axle on it, and an end of gear shaft stretches out outside the valve body.
The corresponding vertically position limit pin that is provided with limit spring in the center of described rack shaft.
Described valve along circumferentially on the position corresponding with valve seat die casting seal ring is arranged.
The upper end of described gear shaft is provided with stop collar, and its valve position direction board places on the stop collar, and the square of being convenient to handover operation is made in the termination.
Described valve body also can be made into six logical disjunctor valve bodies.
The utility model compared with prior art, tooth bar is secondary to be driven owing to adopted, the structural type of diametric plane contact resilient sealing profusely, and big, the good seal performance of flow is arranged by evidence, and be the good more trend of the big more sealing of pressure, switch advantages such as light and flexible, manufacturing simultaneously, assembling are easily, low, the highly versatile of cost, volume be little, in light weight.
