Abstract
Stainless steel gate valve for oxygen. Valve body and the gasket between the valve gap of mainly having solved present stainless steel gate valve for oxygen be often for simple single layer structure, problem that leakproofness, wearability are not strong. The utility model provides a stainless steel gate valve for oxygen is equipped with the flashboard in its valve body, be connected with the valve rod on the flashboard, and the valve rod upper end is equipped with the hand wheel, corresponds with the flashboard in the valve body to be equipped with sealed complex disk seat, can dismantle on the valve body and be connected with the valve gap, is equipped with seal gasket between valve gap and the valve body opposite face, and seal gasket includes the sandwich layer, and the cladding of sandwich layer outer wall has the metal bag coating. Because this seal gasket includes sandwich layer and metal bag coating, the wearability is also stronger when guaranteeing the leakproofness, and the result of use is better.
Description
Technical field
This utility model relates to valve field, specially oxygen stainless steel sluice valve.
Background technology
Gate valve (gate valve) is an opening and closing element flashboard, and the direction of motion of flashboard is perpendicular with flow direction.When gate valve is closed, sealing surface can rely only on pressure medium and seal, and i.e. relies only on pressure medium and the sealing surface of flashboard presses to the valve seat of opposite side to ensure the sealing of sealing surface, here it is self sealss.Major part gate valve is to use forced seal, and i.e. during valve closing, flashboard is pressed to valve seat by external force to be relied on by force, to ensure the sealing of sealing surface.
Valve body and the valve bonnet seal of the oxygen stainless steel sluice valve in market now typically uses gasket seal to realize, but present pad often simple single layer structure, sealing, wearability are the strongest.
Utility model content
In order to overcome the deficiency of background technology, this utility model provides oxygen stainless steel sluice valve, mainly solves the pad between valve body and the valve gap of present oxygen stainless steel sluice valve often for simple single layer structure, the problem that sealing, wearability are the strongest.
This utility model be the technical scheme is that
Oxygen stainless steel sluice valve, including valve body, it is provided with flashboard in described valve body, connecting on described flashboard has valve rod, described valve rod upper end to be provided with handwheel, is correspondingly provided with described flashboard and seals the valve seat coordinated in described valve body, it is removably connected with valve gap on described valve body, being provided with gasket seal between described valve gap and described valve body opposite face, described gasket seal includes that sandwich layer, described sandwich layer outer wall are coated with metal carbonyl coat.
Described sandwich layer is made up of soft graphite.
Described clad is made up of inconel 600.
The cross section of described clad is C-shaped face.
Being provided with runner in described valve body, described runner includes first flow, the second runner and the 3rd runner that diameter diminishes successively.
Described valve rod upper end is provided with the nut of threaded engagement, and described handwheel drives described nut rotation by key transmission.
Described flashboard is inclined-plane with the corresponding surface of described valve seat.
The beneficial effects of the utility model are: oxygen stainless steel sluice valve, it is provided with flashboard in its valve body, connect on flashboard and have valve rod, valve rod upper end is provided with handwheel, it is correspondingly provided with flashboard in valve body and seals the valve seat coordinated, valve body is removably connected with valve gap, between valve gap and valve body opposite face, is provided with gasket seal, gasket seal includes that sandwich layer, sandwich layer outer wall are coated with metal carbonyl coat.Because this gasket seal includes sandwich layer and metal carbonyl coat, while ensureing sealing, wearability is the strongest, and using effect is more preferable.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of one embodiment of this utility model.
Fig. 2 is enlarged drawing at Figure 1A.
Fig. 3 is the cross-sectional schematic of the gasket seal of one embodiment of this utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings: as shown in the figure, oxygen stainless steel sluice valve, including valve body 1, it is provided with flashboard 2 in described valve body 1, connect on described flashboard 2 and have valve rod 3, described valve rod 3 upper end is provided with handwheel 4, it is correspondingly provided with described flashboard 2 in described valve body 1 and seals the valve seat 5 coordinated, it is removably connected with valve gap 6 on described valve body 1, it is provided with gasket seal 7 between described valve gap 6 and described valve body 1 opposite face, described gasket seal 7 includes that sandwich layer 71, described sandwich layer 71 outer wall are coated with metal carbonyl coat 72.Oxygen stainless steel sluice valve, it is provided with flashboard in its valve body, connect on flashboard and have valve rod, valve rod upper end is provided with handwheel, it is correspondingly provided with flashboard in valve body and seals the valve seat coordinated, valve body is removably connected with valve gap, between valve gap and valve body opposite face, is provided with gasket seal, gasket seal includes that sandwich layer, sandwich layer outer wall are coated with metal carbonyl coat.Because this gasket seal includes sandwich layer and metal carbonyl coat, while ensureing sealing, wearability is the strongest, and using effect is more preferable.
In the present embodiment, as it can be seen, described sandwich layer 71 is made up of soft graphite.Soft graphite possesses beyond the premium properties such as the cold-hot of native graphite itself, corrosion-resistant, self-lubricating, also has the characteristics such as the unexistent softness of native graphite, compression resilience, adsorptivity, ecological environment harmony, biocompatibility, radiation resistance.
In the present embodiment, as it can be seen, described clad 72 is made up of inconel 600.600 alloys are nickel-chromium-iron-based solid solution strengthened alloys, have good high-temperature corrosion resistance and antioxygenic property, excellent cold and hot working and welding technological properties, have satisfied heat resistance and high plasticity below 700 DEG C.
In the present embodiment, as it can be seen, the cross section of described clad 72 is C-shaped face.So sandwich layer can be used for partial denudation sealing outside, opposing metallic layer, and the sealing effectiveness of sandwich layer is more preferable, is so more conducive to prevent leakage.
In the present embodiment, as it can be seen, be provided with runner 11 in described valve body 1, described runner 11 includes first flow the 111, second runner 112 and the 3rd runner 113 that diameter diminishes successively.Diminishing due to diameter medium flows to valve seat when, can accelerate, using effect is more preferable.
In the present embodiment, as it can be seen, described valve rod 3 upper end is provided with the nut 33 of threaded engagement, described handwheel 4 drives described nut 33 to rotate by key transmission.When in use, drive nut rotation by rotating handwheel, and then band ovable valve stem rises or declines, simple in construction, easy to use.
In the present embodiment, as it can be seen, the corresponding surface of described flashboard 2 and described valve seat 5 is inclined-plane.Corresponding, valve seat and flashboard are also correspondingly provided with inclined-plane, such flashboard under press when can preferably contact with valve seat, reinforcement sealing.
Embodiment is not construed as restriction of the present utility model, but any based on spirit improvements introduced of the present utility model, all should be within protection domain of the present utility model.
