Description
Technical field
The utility model relates to a kind of valve, especially a kind of camflex valve.
Background technique
Camflex valve is widely used in the industry fields such as oil, chemical industry, metallurgy, iron and steel, papermaking.Camflex valve has been owing to having absorbed the part advantage of ball valve and butterfly valve, have simple in structure, volume is little, lightweight, larger rated flow coefficient is arranged, adjustable extent is large, the serviceability temperature scope is wide, leakage rate is little, stable advantages of higher.Therefore camflex valve is specially adapted to the use in the industrial field of the adjusting of the large slurry of above-mentioned this viscosity and granule medium and cut-out.
General camflex valve comprises valve body and valve seat, is provided with valve shaft in the valve body, and valve shaft is provided with spool, and valve shaft is finished the action that opens or closes valve seat with movable valve plug under the effect of actuator.Yet there is following defective in above-mentioned camflex valve: because valve shaft is connected with actuator, it does not axially have spacing.When being high-pressure medium in the valve pocket of camflex valve, valve shaft is easily under pressure along the axle sleeve slippage that makes progress, thereby dieback actuator affects the normal use of camflex valve.If valve shaft does not connect actuator, be under the pressure-acting of high-pressure medium in the valve pocket of camflex valve, serious, valve shaft may fly out from axle sleeve, cause dielectric leakage, and bring the hidden danger of production safety, but also can bring threat to field personnel's personal safety.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, reasonable in design, axial displacement has the camflex valve of position-limiting action to valve shaft.
To achieve these goals, the technical solution adopted in the utility model is: a kind of camflex valve, comprise valve body, valve gap and valve seat, valve body is fixedly connected with valve gap, be provided with valve shaft in the valve body, offer the groove that passes for valve shaft on the valve gap, be provided with filler between groove wall and the valve shaft, filler is provided with guideway towards an end of valve body, the filler the other end is provided with Gland, and guideway is set on the valve shaft, also is provided with the spool of setting corresponding to valve seat on the valve shaft, it is characterized in that: offer circular groove on the described valve shaft, be embedded with divided ring in the circular groove, the divided ring internal diameter is less than the valve shaft external diameter and greater than the circular groove internal diameter, and the divided ring external diameter is greater than the valve shaft external diameter, described guideway one end offers ring-shaped step, and described divided ring is positioned on the described ring-shaped step.
As further setting of the present utility model, also be provided with liner between described guideway and the filler, insert is located on the valve shaft, and liner is compressing described divided ring.
As further setting of the present utility model, the contact segment between described valve seat and the valve body also is provided with sealing gasket.
Adopt such scheme, the utility model is axially mobile in the groove of valve gap in order to prevent valve shaft, and offered circular groove at valve shaft, be embedded divided ring in the circular groove, because divided ring is embedded in circular groove, the divided ring internal diameter is greater than the circular groove internal diameter, thus this divided ring can in circular groove, rotate, thereby guarantee valve shaft under the drive of actuator, to rotate and can not be subjected to the restriction of divided ring and affect; In addition, the divided ring external diameter is greater than the valve shaft external diameter, so the part that divided ring exceeds valve shaft can produce position-limiting action to the axial motion of valve shaft, and divided ring also can be subject to the restriction at circular groove edge and can not deviate from circular groove simultaneously.In addition, the ring-shaped step of guideway upper edge can be used as divided ring and exceeds the platform that valve shaft is partly placed, and is arranged so that like this mounting point of divided ring is more stable.And also being provided with liner on the divided ring, this liner is compressing divided ring under the compression of filler, Gland, divided ring is further limited in the axial displacement of valve shaft.Contact segment between above-mentioned valve seat and the valve body also is provided with sealing gasket, so that be not direct rigid contact, has improved the seal that is connected between valve seat and the valve body between the two.
Below in conjunction with accompanying drawing the utility model is further described.
