Description
Art
The present invention relates to a kind of valve, is especially provided with three valve rods and gear drives the three valve rod gears sealing valve plate to drive seal valve。
Background technology
At present, in existing valve, the above valve of big orifice DN350 generally has gate valve, ball valve, dish valve etc., produce for many years in the practice of valve at us and find there is shortcomings: the problems such as it is big that they all exist opening and closing moment, easy to wear, assembling difficulty, cost is high, assembling complexity, opens moment big.Concrete defect has following several aspect: 1. dish valve flow resistance coefficient is big, assembling complexity, and sealing is poor, it is easy to abrasion.2. gate valve opens that moment is big, stroke length, inconvenient operation.3. the ball valve sealing life-span is short, cost is high.With tangential direction motion seal between the valve seat of conventional valves and seal and spheroid, dish plate, flashboard etc., frictional force between valve valve seat and seal so can be made very big, valve opening and to close moment very big, and valve seat and seal all easily effect of attrition sealing life.Make a general survey of big orifice valve products market；Be highly desirable to a kind of applied widely, good airproof performance, price are relatively low, open and close the little valve of moment.
Summary of the invention
In order to overcome the shortcomings and deficiencies of existing big orifice valve products, the present invention provides a kind of valve, is especially provided with three valve rods and gear drives the three valve rod gears sealing valve plate to drive seal valve。
The technical solution adopted for the present invention to solve the technical problems is: adopt the operation principle that orthogonal gear, screw thread rotation are advanced, make straight contact crush seal between valve seat and valve plate, particularly as follows: be provided with three special valve rods, it is front upper valve rod, rear upper valve rod and lower valve rod respectively；Valve plate concentric locating is positioned on the twin shaft at a center by rear upper valve rod and lower valve rod, so that valve plate stably opens and closes, on rear upper valve rod, device is with handles, clutch and chain wheel, handle is installed on the clutch, pulling handle clutch can the action respectively of transmission main valve plate or valve seat, when closing valve；After pulling handle driven by clutches clockwise, upper valve rod rotates and makes main valve plate closing passage, continue to pull clockwise spanner clutch to stop upper valve rod transmission backward and to chain wheel transmission, chain wheel is by upper valve rod before chain drive, when front upper valve rod rotates, driving gear advances throw-out collar tooth to make screw thread throw-out collar rotation displacement close to main valve plate, the distance between screw thread throw-out collar and main valve plate is made to reduce, make to contact sealing until screw thread throw-out collar is closely close to main valve plate, valve closing completes, when valve opened by needs；Pulling handle counterclockwise, screw thread throw-out collar rotates give up the throne releasing and main valve plate close contact, and main valve plate Unscrew passage then, valve is opened.This valve mechanism unique seal superior performance solves short defect of traditional all kinds of valve seal unstable properties life-span, and good stability long service life, is special good, easy to operate, easy to manufacture, the novel valve that cost is low of a kind of applied widely, sealing.
The invention has the beneficial effects as follows；Improve the sealing property of valve, and long-acting stable, easy to operate, quick, efficient.

Detailed description of the invention
In FIG；The upper unit of valve body (1) has front upper valve rod (2) and rear upper valve rod (5), clutch (29) is had at the upper device of rear upper valve rod (5), the upper device of clutch (29) has handle (17) and big sprocket wheel (15), having chain (14) to be connected on the minor sprocket (13) on front upper valve rod (2) on big sprocket wheel (15), the lower device of valve body (1) has rear upper valve rod (5).
In fig. 2；Main valve plate (10) concentric locating is positioned on the twin shaft at a center by rear upper valve rod (5) and lower valve rod (11), open and close so that main valve plate (10) is stable, handle (17), clutch (29) and big sprocket wheel (15) is had at the upper device of rear upper valve rod (5), handle (17) is arranged on clutch (29), pull handle (17) clutch (29) and get final product transmission main valve plate (10) or screw thread throw-out collar (7) action, when closing valve；After pulling handle (17) clutch (29) transmission clockwise, upper valve rod (5) rotates and makes main valve plate (10) closing passage, continue to pull clockwise handle (17) clutch (29) to stop upper valve rod (5) transmission backward and to big sprocket wheel (15) transmission, again through the minor sprocket (13) on upper valve rod (2) before chain (14) transmission, before minor sprocket (13) drives, upper valve rod (2) rotates, driving gear (3) advances throw-out collar tooth (4) to make screw thread throw-out collar (7) rotation displacement close to main valve plate (10), the distance between screw thread throw-out collar (7) and main valve plate (10) is made to reduce, until screw thread throw-out collar (7) and main valve plate (10) are closely close to, contact is made to seal, when valve opened by needs；Can pulling handle (17) counterclockwise, make screw thread throw-out collar (7) rotate give up the throne releasing and main valve plate (10) close contact, main valve plate (10) rotates and makes valve passage open then.
