Abstract
The utility model is characterized in that an upper rod (1), a lower rod (2), an inserting plate (3), and a roller (5) descends in an oblique slot (5), a casing frame and a valve clack (6) are spread to be attached tightly to a valve seat (7), and a valve is closed; whereas, the inserting plate (3) and the roller (4) ascends in the oblique slot (5), the casing frame and the valve clack (6) are furled, and the valve seat (7) is disengaged, so that the pressure at an inlet and an outlet can become balanced, an assembly rotates through 90 DEG anticlockwise, and the valve is opened.
Description
The invention belongs to mechanical industry, valve technology field.
From " valve sealing structure of bracing type " patent No.: 85204475.5,87100516.6 and " High Temperature High Pressure ball valve and butterfly valve " patent No.: 92109430.2 have adopted since the technology such as combination spheroids, combination butterfly plate, combination cock, the patent No. particularly: since 92109430.2 patent of invention technology were implemented preferably, promoted, the advantage of valve sealing structure of bracing type was more and more good by valve manufacturer and valve applying unit.But existing combination spheroid, combination butterfly plate, combination cock volume are bigger, it is bigger that lifting travel when support is held together takies the outer space of assemblying body, makes the volume of valve bigger than normal, weight lays particular stress on, and cost increases, during slagging scorification, influence the upper and lower operation of the lifting part in the assemblying body in the valve pocket.
The purpose of this invention is to provide a kind of sealing structure with inserting plate in oblique slot to close it for valve that is applicable to ball valve, butterfly valve, stopcock.
All have a cover combination spheroid, combination butterfly plate, combination cock in described ball valve, butterfly valve, the stopcock valve pocket.Combination spheroid, combination butterfly plate, combination cock mainly are formed by combining by key in shell frame, plate, skewed slot and the skewed slot or roller.The valve rod rotation drives the assemblying body rotation, the valve rod lifting, drive the plate lifting, plate relies on key or the roller in skewed slot and the groove to strut the shell frame, draw the shell frame in, and makes ball clack on the shell frame or butterfly lobe or plug lobe be adjacent to valve seat, break away from valve seat, and finish valve closing, open function.Its major character is: the combination spheroid in ball valve, butterfly valve, the stopcock valve pocket, combination butterfly plate, combination cock mainly are to be combined by key or roller that plate in the middle of shell frame and the shell frame and the skewed slot on shell frame or the plate cooperate with skewed slot.According to the needs of making, installing and use, ball clack, butterfly lobe, plug lobe can be an integral body with the shell frame, also can be divided into two recombinants with the shell frame, and can finely tune to the distance between the valve seat.Be furnished with two shell framves in general combination spheroid, combination butterfly plate, the combination cock, when valve only needs one-way sealing, also can only join a shell frame.Skewed slot on described shell frame or the plate can be one, also can be many, is furnished with a key or a roller in the groove, also can join many keys or follow roller more, generally be the ascending, descending in skewed slot of key or roller, if when skewed slot is arranged on the plate, skewed slot directly and the synchronous ascending, descending of plate.Generally be that plate promotes, the shell frame draws in, and plate descends, and the shell frame struts, if change the skewed slot direction, then for plate promotes, the shell frame struts, and plate descends, and the shell frame draws in.Described skewed slot is generally horizontal, according to the needs of relative position, also can be sometimes and intersects or arranged superposed.Described plate is connected, locatees with upper and lower bar.
The present invention had both reduced the volume of assemblying body compared with prior art, again can be with the ascending, descending stroke basic controlling of plate in the middle of assemblying body.The valve volume is reduced, weight saving, cost lowers, but also effectively solved slagging scorification in the valve pocket and influence the operation problem of ascending, descending part in the assemblying body.
The concrete structure of invention is provided by following embodiment and accompanying drawing:
Accompanying drawing is the combination sphere structure schematic representation according to a kind of ball valve of the present invention's proposition.
Upper boom (1), lower beam (2) are descending in skewed slot (5) together with plate (3) and roller (4), left side shell frame (6), right shell frame (7) are strutted, with bolt (8), resilient pad (9) left ball clack (10) that is connected with left shell frame (6) and the right ball clack (11) that is connected with right shell frame (7), be adjacent to left and right valve seat (12), (13), ball valve is closed.Upper boom (1), lower beam (2) are up in skewed slot (5) together with plate (3) and roller (4), left side shell frame (6), right shell frame (7) are drawn in the left and right ball clack (10), (11) that are connected with left and right shell frame (6), (7) and are thrown off left and right valve seat (12), (13), draw in to the valve seat center, inlet/outlet two ends pressure medium begins balance, the combination spheroid is rotated counterclockwise 90 degree again, and ball valve is opened.
The present invention and lifting add the valve opening and closing respective outer side edges utilization of rotation, can design, produce seriation ball valve, butterfly valve, stopcock new product.
Claims (1)
- Be furnished with in ball valve, butterfly valve, the stopcock valve pocket inserting plate in oblique slot to close it formula sealing configuration the combination spheroid, the combination butterfly plate, the combination cock assemblying body, it is characterized in that:A. assemblying body is mainly combined by shell frame and plate that can lifting in the middle of the shell frame and key or roller,Be equipped with skewed slot on shell frame or plate, key or roller unit are in the middle of skewed slot;B. being adjacent to the ball clack of sealing or butterfly lobe or plug lobe with valve seat on the assemblying body links to each other with the shell frame.
