Description

Laborsaving keying ball valve

Technical field

The utility model is related to a kind of valve, especially a kind of laborsaving keying ball valve.

Background technology

Valve is for being opened and closed pipeline, control flow, adjusting and control pumped (conveying) medium parameter (temperature, pressure and flow) The attachment of pipeline；Have for the valve (especially ball valve) for increasing valve erosion degree medium for opening and closing water etc., for a long time The case where being not turned on valve, causing to be difficult to open to valve needs prodigious strength that could be opened to the spool of valve, Especially for the valve of fire hydrant, when on fire, Ms, the old man of strength weakness be difficult it is opened, if it exceeds Open and close operation is not carried out to it for many years, male person between twenty and fifty are difficult to be opened to it, cause no small security risk.

Utility model content

The utility model will solve the disadvantage that the above-mentioned prior art, provide a kind of laborsaving keying for capableing of laborsaving opening valve Ball valve meets user and does not have to for a long time in valve, the demand that when being blocked by rusty stain, also can easily open and close.

The utility model solves the technical solution of its technical problem use：This laborsaving keying ball valve, including valve body, valve body On spool is installed, valve rod is installed on spool, the driving mechanism rotated for labor-saving strap ovable valve stem is installed on valve body, drive Mechanism includes the frame body being fixed at valve body, and spur gear one is fixed on the top surface of valve rod, and the side of spur gear one is equipped with It is rotatably connected on shaft one on frame body and longitudinally disposed, the spur gear two coordinated with spur gear one, frame are fixed in shaft one It is rotatably connected to longitudinally disposed shaft two on body, spur gear three is fixed in shaft two, the top of shaft two is located at outside frame body Side is simultaneously fixed with turntable, the spur gear four being fixed in shaft one above spur gear two, spur gear four and spur gear three it Between be rotatably connected on frame body equipped with two and longitudinally disposed shaft three and shaft four, fixed respectively in shaft three and shaft four There are spur gear five and spur gear six；Spur gear three and spur gear six, spur gear six and spur gear five, spur gear five and spur gear four Respectively gear engagement together, between spur gear two, spur gear three, spur gear four, spur gear five, spur gear six size it is identical and Between transmission ratio ratio it is also identical be 1:1, the transmission ratio ratio between spur gear two and spur gear one is more than or equal to 5： 1.Transmission ratio is the ratio of two driving member angular speed in mechanism, is inversely proportional with the radius of gear；Here pass through biography of different sizes The gear of dynamic ratio is operated, the mode relative to traditional Open valve, it is only necessary to which traditionally 20% power below can be right The spool of valve is opened, even if having can easily be opened if rusty stain blocking, old man, Ms can easily open, to Avoid unnecessary security risk；Here the effect of spur gear five and spur gear six is arranged between spur gear three, spur gear four is, For power transmission and when may insure that turntable rotates clockwise, spool be also to be followed by rotate clockwise, consequently facilitating right The manipulation of valve.

Further perfect, the both sides of spur gear one are fitted with spur gear two, shaft one, spur gear four, spur gear three Both sides are fitted with spur gear five, spur gear six and shaft three and shaft four.This set can improve the band to spur gear one Dynamic balance opens spool to more more effortless, and the abrasion of spool side will not all occur for long-play Excessive situation behaves and more stablizes.

Further perfect, valve body is equipped with bearing, and outer ring and the valve body of bearing are fixed together, and the inner ring of bearing is socketed in valve On bar outer surface.This set, resistance smaller that can be when driving valve core rotation, suffered by spool.

The utility model has the advantages that：The utility model smart structural design, reasonable, pinion gear drive canine tooth rotation It is dynamic, then the mode with ovable valve stem and valve core rotation, the rotation difficulty to spool can be substantially reduced, even if valve for a long time not into Row opens and closes operation there is a situation where getting rusty to block, and also can easily open, is worthy of popularization.
