Abstract
The utility model relates to valve technology field, especially a kind of novel all-welded ball valve, it is characterized in that, comprise: movable valve gap, spheroid, wearing layer, runner, valve seat is secondary, valve rod screw, valve stem seal pad, valve seat tiltedly overlaps, valve body, valve seat seals firmly, wearing layer, valve rod, temperature isolation layer, handle, described a kind of novel all-welded ball valve, in the joint of valve rod and spheroid, be provided with valve stem seal pad, for convenience of being connected with spheroid, spheroid is directly inserted in its valve rod lower end, be connected with spheroid, described valve stem seal pad is arranged on valve rod lower end, to prevent that spheroid high temperature from causing valve rod excess Temperature, cause valve stem crack, prevent the quick corrosive wear valve of valve rod high temperature corrosion granule medium.The utility model beneficial effect is: prevent the quick corrosive wear of valve 1.; 2. convenient for maintaining does not need whole valve dismounting; 3. complex labour and stopping production have been avoided.
Description
Technical field
The utility model relates to valve technology field, especially a kind of novel all-welded ball valve.
Background technique
The solid particle medium of traditional Coal Chemical Industry valve under the long-term corrosion implementations of high temperature more easily allows valve rod be worn and fractures, Accelerated Corrosion Failure.
Summary of the invention
For addressing the above problem, the utility model provides a kind of novel all-welded ball valve, described a kind of novel all-welded ball valve, it is characterized in that, comprise: movable valve gap 1, spheroid 2, wearing layer 3, runner 4, valve seat pair 5, valve rod screw 6, valve stem seal pad 7, valve seat is cover 8 tiltedly, valve body 9, the hard sealing 10 of valve seat, wearing layer 11, valve rod 12, temperature isolation layer 13, handle 14, described a kind of novel all-welded ball valve, in valve rod 12 and the joint of spheroid 2, be provided with valve stem seal pad 7, general valve rod 12 directly inserts spheroid 2, be connected with spheroid 2, at valve rod, 12 places are provided with valve stem seal pad 7, to prevent that spheroid 2 high temperature corrosion granule mediums from causing valve rod 12 excess Temperatures, cause the quick corrosive wear fracture of valve rod 12, in valve body 9 upper ends, be provided with movable valve gap 1, its movable valve gap 1 is easy to open, opening movable valve gap 1 just can keep in repair, complex labour and stopping production have been avoided.
The utility model beneficial effect is: prevent the quick corrosive wear of valve 1.; 2. convenient for maintaining does not need whole valve dismounting; 3. complex labour and stopping production have been avoided.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: movable valve gap 1, spheroid 2, wearing layer 3, runner 4, valve seat pair 5, valve rod screw 6, valve stem seal pad 7, valve seat tiltedly overlap 8, valve body 9, valve seat seal 10 firmly, wearing layer 11, valve rod 12, temperature isolation layer 13, handle 14.
Embodiment
As shown in Figure 1, described a kind of novel all-welded ball valve, in valve rod 12 and the joint of spheroid 2, be provided with valve stem seal pad 7, its valve rod 12 directly inserts spheroid 2, be connected with spheroid 2, described valve stem seal pad 7 is arranged on valve rod 12 lower ends, prevent that spheroid 2 high temperature corrosion granule mediums from causing valve rod 12 excess Temperatures, cause the quick corrosive wear fracture of valve rod 12, in valve body 9 upper ends, be provided with movable valve gap 1, its movable valve gap 1 is easy to open, and opens movable valve gap 1 and just can keep in repair, and has avoided complex labour and stopping production.
