Abstract
The utility model relates to a gate valve with a spring on a shutter, which comprises a driving device (1), a support (2), a sealing gland (3), a gasket (4), a valve rod (6), a valve body (7), a connector (8), a shutter and a valve seat (13); the shutter comprises a box type disc (9), a spring seat (11), the spring (12) and a cover plate (10); the spring seat (11) is arranged on the box type disc (9) and connected and fixed together with the box type disc (9); the spring (12) is assembled in an inner cavity of the spring seat (11); and the cover plate (10) is embedded together with the box type disc (9). The shutter is pressed on the valve seat for achieving the effects of closing and sealing under the action of elasticity of the spring, and the valve rod is connected with the shutter and driven by the driving device to rise and descend for achieving the purpose of opening and closing; the gate valve has the characteristics of small size, low cost, attractive model, convenience in installation and use and the like; and the gate valve can be widely used in various environments with granular media, coal slag, coal slurry and aluminums powder in high temperature and high pressure under special working conditions, also achieve the purpose of zero leakage and is secure and reliable to use.
Description
Technical field
The utility model relates to a kind of valve, and particularly a kind of flashboard is provided with the gate valve of spring.
Background technique
In the prior art, gate valve is widely used in chemical industry, power station, oil, shipbuilding, and industrial and agricultural productions such as water conservancy, normally used in the market gate valve has two kinds, and a kind of is the Single disc gate valve, and another kind is a double-flashboard gate valve.The sealing configuration of these two kinds of gate valves all has problems, particularly leakage problem can't satisfy the requirement of modern industrial and agricultural production, especially at special operation condition, some have cinder as Coal Chemical Industry, Aluminum, cement etc., and the environment of granule medium all can't satisfy the requirement of use.Subject matter is that the design of flashboard exists defective, the design of flashboard and valve seat all is tapered, narrow below the last face width, tapered flashboard has the gap in switching process and between the valve seat, particle in the medium will enter in the gap that remains between flashboard and the valve seat when valve switch, and it is impaired to cause valve can't close tight with sealing surface, in addition, gap between flashboard and the valve seat produces collision under the impact of fluid, so that sealing surface also sustains damage.Though, someone has invented a kind of plate valve perpendicular to flashboard, but this gate valve only adapts under stress-free situation and uses, and sealing is poor, distortion will appear in the back use a period of time valve body that dispatches from the factory, cause the generation of leaking, cisco unity malfunction causes unnecessary economic loss to the user.
The model utility content
The purpose of this utility model is to provide a kind of flashboard to be provided with the gate valve of spring, this gate valve has overcome problems of the prior art, particularly adapt to special operation condition, High Temperature High Pressure has granule medium, cinder, coal slurry, environment such as aluminium powder, and reach zero leakage, and cost is low, and is safe and reliable.
The technical solution adopted in the utility model is: a kind of flashboard is provided with the gate valve of spring, comprise drive unit, support, sealing gland, sealing gasket, valve rod, valve body, connector, flashboard, valve seat, drive unit is assemblied in the upper end of support, inner chamber fitting tight gland at support, sealing gasket and valve rod, by sealing gland and sealing gasket valve rod is fixed on the support, support and valve body link together, valve body and valve seat are connected and fixed, inner chamber assembling valve rod at valve body, valve rod and connector link together, connector and flashboard assembling link together, flashboard is assemblied on the valve seat, it is characterized in that: flashboard is by disk cartridge, spring seat, spring and cover plate constitute, disk cartridge is provided with spring seat, and spring seat and disk cartridge are connected and fixed, and spring seat is a tubular, at the cylindrical cavity assembling spring of spring seat, cover plate and disk cartridge are entrenched togather.
Preferably, described spring seat and spring match quantity more than one group.
Preferably, described valve body is provided with and purges mouth.
The beneficial effects of the utility model are: owing to adopt above-mentioned structure, valve rod and flashboard are fixed together by connector and are installed in the middle of the valve body, flashboard is made of disk cartridge, spring seat, spring and cover plate, disk cartridge is provided with spring seat, spring seat and disk cartridge are connected and fixed, because the elastic reaction of spring, flashboard is pressed on reaches the effect of closing tight and sealing on the valve seat, valve rod connects flashboard, promote and decline reaches on-off action by drive unit, purge and mouthful prevent when valve uses granule medium that valve pocket is filled and purge souring; The utlity model has small, characteristics such as cost is low, and is handsome in appearance, easy to install; The utility model can be widely used in special operation condition, and High Temperature High Pressure has granule medium, cinder, and coal slurry, environment such as aluminium powder, and reach zero leakage, safe and reliable.
