Abstract
The utility model discloses an aerify ball formula unloading valve, aerify ball formula unloading valve, which comprises a valve body, valve body top installation inlet flange, valve body one side is the compressed air inlet side, compressed air inlet side -mounting axis of rotation, the axis of rotation is connected with the compressed air inlet tube in the outside, just be equipped with gasbag formula hemisphere in the valve body to the inlet flange below, install sealed face in the valve body between gasbag formula hemisphere top and the inlet flange, gasbag formula hemisphere is fixed on sphere fixing support, a tip of axis of rotation is assigned in sphere fixing support's mounting hole, the valve body opposite side adds the lid and overhauls the blind flange. Should unload grey ball valve and adopt and to inflate the inflatable balloon body, compressed air gets into the gasbag when the spheroid rotates to sealed position, and gasbag formula hemisphere inflation reaches the purpose of cutting off sealed various media with the tight combination of valve body upper seal face, and at first behind the pressure release, the transmission shaft rotates the gasbag when opening the ball valve, and spherical rotation 90, medium flow and not to lead to the fact the sphere wearing and tearing, and it is convenient to examine and repair, long service life.
Description
Technical field
The utility model is related to a kind of unloading valve, more particularly to a kind of inflated ball type unloading valve.
Background technology
Unloading valve be cleaner ash discharge, air-supply and miscellaneous equipment feed capital equipment, it is adaptable to granular material and
Material shape material, traditional Unloading ball valve adopt metal ball body, as medium causes spheroid and sealing surface burn into and spheroid to rub when rotating
Scouring is damaged and causes poorly sealed, causes sphere and sealing surface by dusty gas blow loss, and equipment life is shorter.
Accordingly, it is desirable to provide a kind of new technical scheme is solving the above problems.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of inflated ball type unloading valve.
For solution above-mentioned technical problem, inflated ball type unloading valve of the present utility model, it includes valve body, the body top
Suction flange, the body base installation outlet flange are installed, the valve body side is compressed air inlet side, the compression sky
Gas inlet side installs rotary shaft, and the rotary shaft is connected with the compressed air inlet pipe in outside, just to the valve below suction flange
Gasbag-type hemisphere is provided with vivo, installs sealing surface in the valve body above the gasbag-type hemisphere and suction flange between, it is described
Gasbag-type hemisphere is fixed on sphere hold-down support, and the one end of the rotary shaft is assigned in the installing hole of sphere hold-down support
Interior, the valve body opposite side adds a cover maintenance blind flange.
The beneficial effects of the utility model：The Unloading ball valve adopts inflation spheroid, turns to sealing station in spheroid
When compressed air enter air bag, the expansion of gasbag-type hemisphere is tightly combined with sealing surface on valve body and reaches the various media of cut-out sealing
Purpose, when ball valve is opened after air bag pressure release first, drive axis, 90 ° of spherical rotation, media flow do not result in sphere mill
Damage, maintenance is convenient, long service life.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1st, valve body, 2, suction flange, 3, compressed air inlet side, 4, rotary shaft, 5, gasbag-type hemisphere, 6, upper close
Front cover, 7, sphere hold-down support, 8, installing hole, 9, maintenance blind flange, 10, compressed air inlet pipe, 11, outlet(discharge) flange.
Specific embodiment
In order to deepen to understanding of the present utility model, further is made to the utility model below in conjunction with embodiment and accompanying drawing
Describe in detail, the embodiment is only used for explaining the utility model, does not constitute the restriction to protection domain of the present utility model.
As shown in figure 1, inflated ball type unloading valve of the present utility model, it includes valve body 1, installs import method at the top of valve body 1
Blue 2,1 bottom installation outlet flange 11 of valve body, 1 side of valve body is compressed air inlet side 3, and compressed air inlet side 3 is installed and turned
Moving axis 4, rotary shaft 4 are connected with the compressed air inlet pipe 10 in outside, just to being provided with air bag in the valve body 1 below suction flange 2
Formula hemisphere 5, installs sealing surface 6 in the valve body 1 above gasbag-type hemisphere 5 and between suction flange 2, and gasbag-type hemisphere 5 is fixed
On sphere hold-down support 7, the one end of rotary shaft 4 is assigned in the installing hole 8 of sphere hold-down support 7, and 1 opposite side of valve body adds
Lid maintenance blind flange 9.
The Unloading ball valve adopts inflation ball（Gasbag-type hemisphere）Body substitutes conventional metals spheroid, turns in spheroid close
During envelope position, compressed air enters air bag, and it is each that the expansion of gasbag-type hemisphere reaches cut-out sealing with 6 tight combination of sealing surface on valve body 1
The purpose of medium is planted, when ball valve is opened after air bag pressure release first, power transmission shaft 4 is rotated, 90 ° of spherical rotation, and media flow will not
Cause sphere abrasion.
The air bag sphere that this equipment is adopted is corrosion-resistant, and when spheroid is rotated, sphere is separated with sealing surface（Air bag ball is turning
Pressure release when dynamic）, abrasion is not resulted in during rotation, substantially increases the life-span of equipment, and this equipment can be online（Need not tear open
Under）Change spare and accessory parts simple and convenient cost-effective.
The ball valve maintenance is convenient, and service life 3-5 is older, regular maintenance, removable parts easy-consuming fitting（Easy-consuming fitting
Life-span was up to more than 1 year）, greatly save enterprise's maintenance cost.
Claims (1)
