Abstract
The utility model discloses a corrode operating mode with lining fluorine butterfly valve level four seal structure, including valve body, disk seat, valve plate and valve rod, during the valve body was located to the disk seat, the valve plate was located in the disk seat and is the face seal with the disk seat, and the valve rod stretches into valve body and disk seat and is the integral type design with the valve plate, and sealed through last bush, end cap respectively between valve body both sides and the valve rod, wherein still was equipped with sealed the pad between end cap and the valve rod, the valve body is equipped with the counter bore to be equipped with gland, dish spring in the counter bore, gland, dish spring in line are connected between valve body and disk seat, still be equipped with O type circle, sealing ring between gland and disk seat or the valve plate. The utility model provides a corrode operating mode with lining fluorine butterfly valve level four seal structure has guaranteed fully through the sealed rational design of level four that the medium forbids outer requirement of leaking, and is applicable in to leaking strict operating mode, especially leaks and to produce the great occasion that influences to environment and production and operation.
Description
Technical field
The utility model relates to a kind of corrosive conditions lining fluorine butterfly valve level Four sealing configuration.
Background technique
At present, the material such as industrial valve many employings carbon steel, stainless steel, dual phase steel, Inco nickel that, Monel, No. 20 alloys.But mainly there is following problem in the valve applying these material manufactures: one, carbon steel and stainless steel cannot meet the corrosion of some superpower aggressive mediums.Two, the cost of material such as dual phase steel, Inco nickel that, Monel, No. 20 alloys is too high.After considering cost and applicability, in succession have producer to develop both at home and abroad and manufacture various lining valve, wherein serving as a contrast fluorine butterfly valve is exactly commonplace one.But the lining fluorine butterfly valve upper and lower valve rod hole position sealing of current domestic and international most of manufacturer production is single or design of Sealing Structure is reasonable not.
Model utility content
The purpose of this utility model is to solve the problem that leaking, moment of torsion is large and the life-span is low easily appears in lower valve rod place on existing lining fluorine butterfly valve, provides a kind of corrosive conditions to serve as a contrast fluorine butterfly valve level Four sealing configuration.
The utility model adopts following technological scheme in order to achieve the above object:
A kind of corrosive conditions lining fluorine butterfly valve level Four sealing configuration, comprises valve body, valve seat, valve plate and valve rod;
Described valve seat is located in described valve body, described valve plate to be located in described valve seat and to be that face seals with described valve seat, described valve rod stretches into described valve body and described valve seat and is unitary design with described valve plate, and seal respectively by upper lining, plug between described valve body both sides and described valve rod, be also provided with sealing gasket between wherein said plug and described valve rod;
Described valve body is provided with counterbore, and is provided with gland, disc spring in described counterbore, and described gland, disc spring are in line and are connected between described valve body and described valve seat;
O type circle, seal ring is also provided with between described gland and described valve seat or described valve plate.
Preferably, described seal ring is made up of teflon.
Preferably, described O type circle is made up of fluorine rubber.
By the appropriate design that level Four seals, the corrosive conditions lining fluorine butterfly valve level Four sealing configuration that the utility model provides fully ensure that medium does not allow the requirement leaked outside, be applicable to and strict operating mode is required to leakage, particularly leak and can produce considerable influence occasion to environment and the production and operation.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a application's part, does not form improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model embodiment cross-sectional view;
Fig. 2 is the close-up schematic view of Fig. 1.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model with illustrative examples of the present utility model and explanation at this, but not as to restriction of the present utility model.
As shown in Figure 1, 2, a kind of corrosive conditions lining fluorine butterfly valve level Four sealing configuration, comprises valve body 1, valve seat 9, valve plate 12 and valve rod 3, described valve seat 9 is located in described valve body 1, described valve plate 12 to be located in described valve seat 9 and to be sealed in face with described valve seat 9, described valve rod 3 stretches into described valve body 1 and described valve seat 9 and with described valve plate 12 in unitary design, and respectively by upper lining 2 between described valve body 1 both sides and described valve rod 3, plug 10 seals, wherein go up the kit form that lining 2 adopts nylon to coordinate with O type circle, make it namely there is labyrinth seal, there are again hydrodynamic pressure selfsealings, sealing gasket 11 is also provided with between described plug 10 and described valve rod 3, plug 10 is adopted to compress, convenient installation, dismounting and replacing sealing gasket 11, can change online, described valve body 1 is provided with counterbore, and in described counterbore, be provided with gland 6, disc spring 5, described gland 6, disc spring 5 are in line and are connected between described valve body 1 and described valve seat 9, described disc spring 5 adopts four groups of involutory forms, fully ensure that when sealing part abrasion, what still can reliably continue provides sealing force, O type circle 7, seal ring 8 is also provided with between described gland 6 and described valve seat 9 or described valve plate 12, in the present embodiment, O type circle 7, seal ring 8 are located between described gland 6 and described valve plate 12, the teflon that seal ring 8 material selection corrosion resistance is identical with valve seat 9, O type circle 7 is also the fluorine rubber adopting corrosion resistance best, fluororubber O-type ring 7 intensity is good, makes sealing effect better.
In above-described embodiment scheme, face between valve plate 12 and valve seat 9 seals and forms the first preventing medium from leaking and seal, seal ring 8, O type circle 7 are respectively the sealing of second and third road, upper lining 2 and sealing gasket 11 are the 4th road sealing, namely described level Four sealing has mechanical seal, have again packing seal to also have pressure energized seal, multiple sealing means combination, fully ensure that the sealing in lower valve rod 3 hole.
When being in low pressure or pneumatics, valve seat 9 contacts with valve plate 12, and the power that valve seat 9 is provided by disc spring 5 reaches sealing; In the operating mode that pressure is higher, pressure promotes valve seat 9 boss and presses to seal ring 8, realizes self-energized seal; Even if when above-mentioned two seals lost efficacy, the O type circle 7 of three seals also can provide reliable sealing; When three seals also goes wrong, upper lining 2 and sealing gasket 11 still can ensure that medium can not leak outside, and realize sealing.
Above the technological scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and mode of execution, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, embodiment and application area all will change, and in sum, this description should not be construed as restriction of the present utility model.
