Abstract
The warehouse pump charging and discharging ceramic cup valve of the utility model belongs to the technical field of valve, which comprises a valve body, a cup valve flap and a start and stop structure of valve flap. A circular polytetrafluoroethylene valve seat is fixed on the valve body, and a ceramic ring is fixed to a sealing part on the cup valve flap and matched with the valve seat; the outer surface of the ceramic ring and the valve seat form a sealing pair; a ceramic cup housing is installed on the cup valve flap and above the ceramic ring. The inner surface of the polytetrafluoroethylene valve seat is an inner cone surface, and accordingly, the outer surface of the sealed ceramic ring is an outer cone surface matched with the inner cone surface of the valve seat. The sealing pair is the soft and hard matching with good sealing property; the replaceable polytetrafluoroethylene valve seat makes it very convenient to replace and repair the valve sealing pair; the ceramic housing on the cup valve flap plays a protection role to the metal basal body of the cup valve flap, which avoids the erosion and abrasion breakage of the valve flap by the medium stream. The utility model is convenient in maintenance and reliable in operation.
Description
Technical field
The utility model belongs to valve technology field, particularly a kind of storehouse pump input and output material pottery cup valve that uses on the pipeline that vertically is installed on.
Background technology
In the material-transporting system of industries such as cement, thermal electric generation, metallurgy, chemical industry, a kind of storehouse pump air-transport system that is widely adopted is arranged, the major equipment of this system is the storehouse pump, its function is for collecting ashes, and gas and ashes are fully mixed, and gas ash compound is transported to destinations such as grey storehouse in high-speed motion by regulating the pump internal pressure.In service in system, because the medium of carrying by valve is the compound of graininess dry powder substance, valve is in closing closed procedure, very easily press from both sides the pad pumped (conveying) medium between the sealing surface, cause partially sealed not tight, folder pad leakage has the high speed media particle to pass through, and the breakthrough leakproofing material is had the very strong abrasive action of washing away.Because traditional bell storehouse pump valve is a metal construction, its leakproofing material wears no resistance, and crevasse meeting news speed enlarges, and sealing effectiveness news speed worsens, even causes the valve body perforation, causes equipment thoroughly to damage.
The utility model content
The utility model purpose is to provide a kind of anti-storehouse pump input and output material strong towards mill property, long service life ceramic cup valve.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of storehouse pump input and output material pottery cup valve, comprise valve body, bell flap and flap mechanism for opening/closing, on valve body, be fixed with the cyclic polytetrafluoroethylene valve seat, sealing place that matches with valve seat on bell flap is fixed with ceramic ring, this ceramic ring outer face and valve seat constitute sealing pair, add a ceramic bell-jar above this ceramic ring on the bell flap.
Described polytetrafluoroethylene valve seat interior surface is an inner conical surface, and leak free ceramic ring outside face that matches with it is the male cone (strobilus masculinus) that matches with the valve seat inner conical surface.
In the utility model, sealing pair is that soft or hard cooperates good seal performance.Because ceramic hardness is far longer than the hardness of media particle, makes bell flap matrix under the protection of pottery lining cover, avoid the medium erosive wear, thereby prolonged the service life of valve greatly.The polytetrafluoroethylene valve seat is replaceable, overhauls more convenient.The utility model provides reliable guarantee for the long-time running of storehouse pump air-transport system.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment, a kind of storehouse pump input and output material pottery cup valve, form by the bell flap metallic matrix 5 in valve body 1 and the valve body 1, on valve body 1, compress and with the cyclic polytetrafluoroethylene valve seat 2 of a band of the fastening installation of screw inner conical surface with pressing plate 3, at bell flap metallic matrix 5 and valve seat 2 corresponding positions, a ceramic-seal ring 4 is installed, this ceramic-seal ring 4 is pressed on the bell flap by metal platen 7, and metal platen 7 usefulness screws are fastened on the bell flap.Bell flap metallic matrix 5 surfaces add is stamped pottery lining cover 6, and pottery serves as a contrast cover 6 lower ends and ceramic-seal ring 4 holds out against, the upper end is fixed with pressing plate and screw in compression.Bell flap metallic matrix 5 is hinged through bearing pin 8 and rocking bar 9, and rocking bar 9 is driven by the piston of cylinder 10, swing up and down, when on put when flap, valve seat are adjacent to mutually, valve is in closed condition; When the bottom to flap be higher than valve seat suitably apart from the time, valve is in opening.
Claims (2)
1, the ceramic cup valve of a kind of storehouse pump input and output material, comprise valve body, bell flap and flap mechanism for opening/closing, it is characterized in that, on valve body, be fixed with the cyclic polytetrafluoroethylene valve seat, sealing place that matches with valve seat on bell flap is fixed with ceramic ring, this ceramic ring outer face and valve seat constitute sealing pair, add a ceramic bell-jar above this ceramic ring on the bell flap.
2, the ceramic cup valve of storehouse pump input and output material as claimed in claim 1 is characterized in that described polytetrafluoroethylene valve seat interior surface is an inner conical surface, and leak free ceramic ring outside face that matches with it is the male cone (strobilus masculinus) that matches with the valve seat inner conical surface.
