Description
Technical field
The utility model belongs to valve technology field, refers to a kind of upper dress formula Full-diameter eccentric hemisphere valve.
Background technique
As everyone knows, upper dress formula Full-diameter eccentric hemisphere valve is current global mechanism footpath; There is the pressure loss little, resistance to abrasion of particles, automatic compensation sealing is reliable, be applicable to high flow rate medium, the features such as life-span long switch is light, easy to maintenance, in some specific occasions, this valve can not affect the normal operation of pipe-line system during rushing to repair, as long as close the operation with pressure that just can recover pipeline immediately suitable for reading rapidly after taking-up spheroid assembly parts, the lost revenue that repairing valve is caused is reduced to minimum degree.But there is unreasonable structure in the upper dress formula Full-diameter eccentric hemisphere valve on existing market, causes sealing effect undesirable, thus affect the whole service life of product.
Summary of the invention
For the deficiency existed in background technique, the purpose of this utility model is to provide a kind of upper dress formula Full-diameter eccentric hemisphere valve.
For achieving the above object, the utility model provides following technological scheme: dress formula Full-diameter eccentric hemisphere valve in one, comprise valve body, the upper end of valve body is provided with valve gap, lower end is provided with bonnet, spheroid is provided with between valve gap and bonnet, spheroid is provided with spherical crown, spherical crown is provided with valve seat, seal ring is provided with between valve seat and valve body, valve gap is provided with upper valve rod, bonnet is provided with lower valve rod, described upper valve rod and spheroid are fixed together by pin, filler dual fail-safe dish is provided with between upper valve rod and valve gap, graphite packing is provided with between filler dual fail-safe dish and upper valve rod, the upper end of graphite packing is provided with Gland, be connected by bolt and nut between Gland with valve gap.
Above-mentioned upper valve rod is arranged on valve gap by axle sleeve.
Above-mentioned filler dual fail-safe dish is connected by bolt and nut with valve gap.
Seal ring is provided with between above-mentioned filler dual fail-safe dish and upper valve rod, valve gap.
Above-mentioned filler dual fail-safe dish is arranged on the upper end of axle sleeve.
The utility model beneficial effect compared to existing technology: be provided with filler dual fail-safe dish between the utility model upper valve rod and valve gap, graphite packing is provided with between filler dual fail-safe dish and upper valve rod, the upper end of graphite packing is provided with Gland, such structure can improve the sealing effect of product, extend the whole service life of product, and also do not affect on-line maintenance, very easy.

1-valve body; 2-valve gap; 3-bonnet; 4-spheroid; 5-spherical crown; 6-valve seat; 7-upper valve rod; 8-lower valve rod; 9-pin; 10-filler dual fail-safe dish; 11-graphite packing; 12-Gland; 13-axle sleeve.
Embodiment
Below in conjunction with drawings and Examples, to embodiment of the present utility model as preferred detailed description.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 1-2, dress formula Full-diameter eccentric hemisphere valve in one, comprise valve body 1, the upper end of valve body 1 is provided with valve gap 2, lower end is provided with bonnet 3, spheroid 4 is provided with between valve gap 2 and bonnet 3, spheroid 4 is provided with spherical crown 5, spherical crown 5 is provided with valve seat 6, seal ring is provided with between valve seat 6 and valve body 1, valve gap 2 is provided with upper valve rod 7, bonnet 3 is provided with lower valve rod 8, described upper valve rod 7 is fixed together by pin 9 with spheroid 4, filler dual fail-safe dish 10 is provided with between upper valve rod 7 and valve gap 2, graphite packing 11 is provided with between filler dual fail-safe dish 10 and upper valve rod 7, the upper end of graphite packing 11 is provided with Gland 12, be connected by bolt and nut between Gland 12 with valve gap 2.
As preferably, above-mentioned upper valve rod 7 is arranged on valve gap 2 by axle sleeve 13.
As preferably, above-mentioned filler dual fail-safe dish 10 is connected by bolt and nut with valve gap 2.
As preferably, between above-mentioned filler dual fail-safe dish 10 and upper valve rod 7, valve gap 2, be provided with seal ring.
As preferably, above-mentioned filler dual fail-safe dish 10 is arranged on the upper end of axle sleeve 13.
In the utility model, if upper valve rod 7 seal leakage, please the bolt on Gland 12 is wrenched; Be wrenched as the bolt on Gland 12 and still leak, can unload actuator, change graphite packing 11 or add graphite packing 11, it is easy that such structural design makes to keep in repair very.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, under the prerequisite not departing from the utility model know-why, make some improvement and modification also should be considered as protection domain of the present utility model.
