Background technique
In the existing technology, the structure of butterfly valve mostly is to comprise valve body, rotating shaft and valve plate, and rotating shaft is installed in the axis hole of valve body; Valve plate is through the rotating shaft driven rotary, and the higher authorities of rotating shaft expose valve body, pulls the rotating shaft rotation through spanner; When not in use, spanner is just taken away, and the shortcoming that this structure exists is: 1, position-limit mechanism is not set on the valve body; Operator fully with the folding of feeling to pull valve plate, are difficult to control the precision of valve plate when using wrench operated; 2, if want the flow of controlling plumbing fixtures, valve plate is controlled at the open mode of several angle, under the impact of current for a long time, can change the angle that valve plate is opened, thereby cause flow to change.Valve plate directly cooperates with valve opening on the other hand, and sealing effect is poor.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of valve plate folding accurate, and valve plate half-open position angle adjustment is accurate, and it is firm to lock, the sealing mechanism of the butterfly valve of valve plate and valve opening good airproof performance and spacing locking device.
The sealing mechanism of the utility model butterfly valve and the technological scheme of spacing locking device are: comprise valve body, valve opening is opened at the valve body center, and valve plate is installed in the valve opening, in valve body, opens axis hole; Rotating shaft is installed in the axis hole, and rotating shaft and valve plate fix, and it is characterized in that described sealing mechanism comprises that the valve opening inwall is equipped with stuffing box gland; Stuffing box gland seals with valve plate mutually, and described spacing locking device comprises and is shaped on fixed plate on the valve body, install adjustment limiting board on the fixed plate; Upper-end surface regulating limiting board is shaped on limiting stopper, and a side of regulating limiting board is shaped on regulating tank, is regulating handle installation on the limiting board; The front end of handle and the upper end of rotating shaft fix, install adjustment bar in handle, and the adjustable lever middle part is equipped with stationary axle; Inwall at the handle middle part has mounting hole, and adjustable lever cooperates mounting spring on the adjustable lever rear end through stationary axle with the mounting hole rotation of handle; Spring contacts with the handle, at its lower end face, is shaped on fixture block at the adjustable lever front end, and fixture block matches with the regulating tank of regulating limiting board.
The utility model discloses a kind of sealing mechanism and spacing locking device of butterfly valve, said valve opening inwall is equipped with stuffing box gland, and stuffing box gland seals with valve plate mutually.Stuffing box gland has been arranged, made good airproof performance between valve plate and the valve body.In the time will opening or closing valve, upwards press the rear end of adjustable lever earlier with finger, spring is squeezed, the front end of adjustable lever is rotated down around stationary axle; Make fixture block break away from the regulating tank of regulating limiting board, use the hand handle with sleeve then, handle drives the rotating shaft rotation; Rotating shaft drives the valve plate rotation, and when handle forwarded the limiting stopper position to, the handle outer wall contacted with limiting stopper; Can't be rotated further, this moment, valve plate also forwarded complete opening or closed fully state to, and finger again comes loose; Change under the effect of spring restoring force the rear end of adjustable lever, and the adjustable lever front end upwards changes, and fixture block is snapped in the regulating tank again.If in the time of will controlling the angle of valve plate unlatching, same rear end of upwards pressing adjustable lever earlier with finger makes fixture block disengaging regulating tank; Handle with sleeve when handle rotates to the angle that needs, unclamps finger then; Fixture block is snapped in the regulating tank of this angle; Fixture block contacts with the cell wall of regulating tank, and it is firm to lock, and prevents that valve plate from producing rotation under the impact of current.
The sealing mechanism of the utility model butterfly valve and spacing locking device, the upper-end surface of said adjusting limiting board are shaped on 0 ° of-90 ° of graduation line, are shaped on pointer at the handle front end, and pointer faces graduation line.Graduation line has been arranged, and the angle of handle adjusting valve plate is accurate.Said valve body is shaped on stiffening rib on the two side.Improve body strength, increase working life.
