Abstract
A kind of rotary wheel of water turbine cylinder body draining valve sealing configuration, valve body is provided with seal washer near the end face of flange of tool withdrawal groove, and plug operating end header structure is interior hexagon.A kind of rotary wheel of water turbine cylinder body draining valve sealing configuration that the utility model provides, copper packing sealing is substituted the rubber seal of O type, and structure plug being operated termination is set to interior hexagon, not only make plug when mounted laborsaving, conveniently reach its design torque, also can make the sealing effect that draining valve reaches better.The utility model structure is simple, and easy accessibility, good sealing effect, Security is high, and may be used on the draining valve of different structure parts, using scope is wide.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly relates to a kind of rotary wheel of water turbine cylinder body draining valve sealing configuration.
Background technique
The seal form of rotary wheel of water turbine cylinder body draining valve design is the rubber seal of O type, and owing to welding closure plate after it is installed, rubber seal is easily aging after being heated, and causes seal failure; In addition, because draining valve plug operating end header structure is straight groove, be difficult to utilize instrument to make it reach design torque, when oil extraction spool hair fastener, when cannot reset, also easily produce oil leakage phenomenon, affect draining valve and normally work.
Model utility content
Technical problem to be solved in the utility model there is provided a kind of rotary wheel of water turbine cylinder body draining valve sealing configuration, improves the sealing effect of draining valve, prevents oil leakage phenomenon from occurring.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of rotary wheel of water turbine cylinder body draining valve sealing configuration, valve body is provided with seal washer near the end face of flange of tool withdrawal groove, and plug operating end header structure is interior hexagon.
Described sealing gasket is copper, and its external diameter size is identical with end face of flange diameter.
A kind of rotary wheel of water turbine cylinder body draining valve sealing configuration that the utility model provides, copper packing sealing is replaced the rubber seal of O type, and structure plug being operated termination is set to interior hexagon, not only make plug laborsaving, convenient when mounted, reach its design torque, draining valve sealing effect also can be made better.The utility model structure is simple, and easy accessibility, good sealing effect, Security is high, and may be used on the draining valve of different structure parts, using scope is wide.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, model utility is described further:
Fig. 1 is the draining valve structure cut-away view of former sealing configuration.
Fig. 2 is the utility model structure cut-away view.
In Fig. 1-2: seal groove 1, tool withdrawal groove 2, valve body 3, plug 4, seal washer 5.
Embodiment
As shown in Figure 2, a kind of rotary wheel of water turbine cylinder body draining valve sealing configuration, valve body 3 is provided with seal washer 5 near the end face of flange of tool withdrawal groove 2, and plug 4 operating end header structure is interior hexagon.
Described seal washer 5 is copper, and its external diameter size is identical with flanged surface diameter.
Replace original O type rubber sealing structure by arranging copper seal washer 5, after being heated, seal washer 5 not easily occurs aging, sealing good stability; Plug 4 operating end header structure is set to interior hexagon, and make plug 4 easy to operate in installation process, more laborsaving, reach its design torque, sealing effect is better.
The external diameter of seal washer 5 is identical with end face of flange 6 diameter, can solve the problem that seal washer 5 moves left and right, make its better tightness.
