The model utility content
For the problem that prior art exists, the purpose of this utility model is to provide a kind of bidirectional metal hard-sealing butterfly valve, and its sealability is reliable, and long service life.
To achieve these goals, the utility model provides a kind of bidirectional metal hard-sealing butterfly valve, it comprises valve body, butterfly plate, upper valve shaft, lower valve shaft, metal o-ring, regulate trim ring, self oiling bearing and positioning ring, described butterfly plate is by described upper valve shaft, described lower valve shaft and described self oiling bearing are installed in the described valve body axle journal, described metal o-ring is installed in the locating slot of described valve body, described adjusting trim ring is installed on the described valve body by adjusting screw, described positioning ring is installed in described upper valve shaft, between described lower valve shaft and the described valve body, and to described butterfly plate formation location, described metal o-ring is Y type elastic metal sealing ring.
Preferably, comprise also that building rubber compound Sealing, described building rubber compound Sealing are installed between described valve body and the described Y type elastic metal sealing ring, and compressed by adjusting screw by described adjusting trim ring.
Preferably, described building rubber compound Sealing is the building rubber compound Sealing of V-type+O type.
Preferably, described Y type elastic metal sealing ring is that stainless steel is made, and the sealing surface that described butterfly plate is in contact with it is pile-up welding hard alloy.
Compared with prior art, bidirectional metal hard-sealing butterfly valve provided by the utility model, its metal o-ring is Y type elastic metal sealing ring, can the auto-compensation bidirectional bearing, have the two way sealed function, be not subjected to during installation MEDIA FLOW to restriction, during butterfly valve forward pressure-bearing, by the initial sealing position of regulation valve body elastic seal ring, form suitable seal pressure with the butterfly plate sealing surface, reach sealing; During the butterfly valve reverse pressure-bearing, the slippage under the effect of pressure medium of valve body elastic seal ring, the bearing strain of compensation butterfly plate, and Y type elastic metal sealing ring has the elastic compensating effect, and resiliently deformable trend butterfly plate sealing surface keeps forming suitable seal pressure with the butterfly plate sealing surface behind the pressurized, reach sealing, can carry out sealing compensation by the adjusting screw on the valve body and regulate, process relatively simply, save supporting special tooling cost.
Further preferably in the mode of execution, comprise that also the building rubber compound Sealing of V-type+O type, described building rubber compound Sealing are installed between described valve body and the described Y type elastic metal sealing ring, and compressed by adjusting screw by described adjusting trim ring; Can stop interior leakage to reach the distortion of elastic expansion recuperation valve body elasticity seal ring after compression, further guarantee the valve seal reliable performance.
Further preferably in the mode of execution, described Y type elastic metal sealing ring is that stainless steel is made, the sealing surface that described butterfly plate is in contact with it is pile-up welding hard alloy, therefore, corrosion-resistant, long service life, valve abrades in opening-closing process and weares and teares little, and can close tighter and tighter, sealability be reliable, and operational torque is little.

Embodiment
The purpose of this utility model provides a kind of bidirectional metal hard-sealing butterfly valve, and its sealability is reliable, and long service life.
In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing the utility model is described in detail; the description of this part only is exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
Please refer to Fig. 1, Fig. 2, in one embodiment, bidirectional metal hard-sealing butterfly valve provided by the utility model mainly is comprised of valve body 1, butterfly plate 6, upper valve shaft 5, lower valve shaft 7, Y type elastic metal sealing ring 4, building rubber compound Sealing 3, adjusting trim ring 2, self oiling bearing 8, positioning ring 9 etc.Self oiling bearing 8 is installed in the valve body axle journal, butterfly plate 6 is installed on the valve body by upper valve shaft 5, lower valve shaft 7 and self oiling bearing 8, Y type elastic metal sealing ring 4 is installed in the locating slot of valve body 1, building rubber compound Sealing 3 is installed between valve body 1 and the Y type elastic metal sealing ring 4, adjusting trim ring 2 is installed on the valve body 1 by adjusting screw and compresses building rubber compound Sealing 3, and positioning ring 9 is installed between valve shaft 5, lower valve shaft 7 and the valve body 1 butterfly plate 6 is formed the location.
Working principle of the present utility model: drive upper valve shaft 5, lower valve shaft 7 rotations by drive unit, driving butterfly plate 6 by upper valve shaft 5, lower valve shaft 7 simultaneously rotates in 90 ° of scopes, butterfly plate is in opens or closed condition, thereby reach the purpose that is communicated with or blocks medium.The utility model realizes that at pipeline the working principle of two way sealed is: during butterfly valve forward pressure-bearing, adjust the initial sealing position of valve body Y type elastic metal sealing ring 4 by regulating trim ring 2, form suitable seal pressure with butterfly plate 6 sealing surfaces, reach sealing; During the butterfly valve reverse pressure-bearing, the slippage under the effect of pressure medium of valve body Y type elastic metal sealing ring 4,6 bearing strains of compensation butterfly plate, and Y type elastic metal sealing ring 4 has the elastic compensating effect, resiliently deformable trend butterfly plate 6 sealing surfaces behind the pressurized, keep forming suitable seal pressure with butterfly plate 6 sealing surfaces, reach sealing.
