Abstract
The utility model relates to an integrated type high performance partitioning valve which comprises a valve body, valve seats, a ball body, a valve rod and transmission mechanism. The valve rod and the valve body are sealed with expanded graphite padding which is fixedly arranged through a padding pressing sleeve and a padding pressing plate. The valve is mainly formed by the valve body and a support in a whole-forging mode. The valve seat on an inlet side is arranged in a valve body channel through a belleville spring seat. A belleville spring is arranged between the belleville spring seat and the valve seat on the inlet side. The belleville spring seat is in interference fit with the valve body channel. The valve seat on an outlet side is in direct interference fit with the valve body. The valve has the advantages that high temperature resistance, high pressure resistance and scouring resistance are achieved, and sealing is reliable. The partitioning valve is suitable for the working conditions of high-temperature, high-pressure and abrasiveness media.
Description
Technical field
The utility model relates to valve field, particularly about a kind of ball valve.The utility model is applicable to the separating valve of high temperature, high pressure, abrasiveness medium operating mode.
Background technique
Ball valve is simple in structure because of it, open-close convenient, the little separating valve that is widely used in a national economy field medium transport pipeline of flow resistance, for high temperature, high pressure, abrasiveness medium operating mode, the general hard seal ball valve that adopts, its structure generally comprises valve body, valve seat, spheroid, valve rod, valve gap, support, driving mechanism, installed by bolt between valve gap and the valve body, support is installed on the valve gap by bolt, and the Graphite pad sealing is set between valve seat and the valve body.Its major defect is to have leakage point between valve gap and the valve body, and high-pressure medium is easily got valve rod, support, and the graphite gasket sheet between valve seat and the valve body is subject to medium and washes away and be worn, and sealing reliability is poor.
Summary of the invention
The purpose of this utility model is the shortcoming that exists for prior art, and a kind of high temperature resistant, high pressure resistant, wear-resistant, integral type high-performance separating valve that sealing reliability is high is provided.
The technical solution of the utility model comprises valve body, valve seat, spheroid, valve rod, driving mechanism, adopt the expanded graphite packing sealing between valve rod and the valve body, this expanded graphite packing is by filler pressing sleeve and hold-down grid fixed installation, mainly be valve body and support solid forging moulding, the suction side valve seat is installed in the valve channel by the butterfly spring abutment, between butterfly spring abutment and the suction side valve seat butterfly spring is set, adopts interference fit between butterfly spring abutment and the valve channel, the direct and valve body interference fit of outlet side valve seat.
In above technological scheme, be provided with the mobile load spring between filler pressing sleeve and the hold-down grid.
In above technological scheme, sealing surface of seat and valve ball sealing surface be the coated with hard alloy respectively.
The utility model has the advantages that valve body and support solid forging moulding, prevent that high-pressure medium from getting valve rod, support, adopt interference fit seal between valve seat and the valve body, have the characteristics such as high temperature resistant, high pressure resistant, resistance to erosion, sealing be reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Integral type high-performance separating valve as shown in Figure 1, comprise valve body 1, valve seat, spheroid 3, valve rod 11, driving mechanism, adopt expanded graphite packing 7 sealings between valve rod 11 and the valve body 1, this expanded graphite packing 7 is by filler pressing sleeve 8 and hold-down grid 10 fixed installations, valve body 1 and support solid forging moulding, avoid support to be got by high-pressure medium together with valve rod 11, the suction side valve seat is installed in valve body 1 passage by butterfly spring abutment 5, between butterfly spring abutment 5 and the suction side valve seat butterfly spring 4 is set, adopt interference fit between butterfly spring abutment 5 and valve body 1 passage, making floats between suction side valve seat and the spheroid 3 cooperates, outlet side valve seat 2 direct and valve body 1 interference fit have avoided adopting between valve seat and the valve body 1 the graphite flake sealing to be washed away by medium.Between butterfly spring abutment 5 inlet end face and valve body 1 vias inner walls, stop ring jump ring 6 is set, valve lever bushing 12 is set between valve rod 11 and the support.
Be provided with mobile load spring 9 between filler pressing sleeve 8 and the hold-down grid 10, the wearing and tearing of auto-compensation expanded graphite packing 7.
Valve seat adopts the pairing grinding to cooperate with spheroid 3, and sealing surface of seat and spheroid 3 sealing surfaces are the coated with hard alloy respectively, improves the wear-resistant and flushing resistance of sealing surface.
