Description
Technical field
The utility model relates to valve technology field, especially a kind of exhaust butterfly valve.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member is disk, and a kind of valve of open and close is reached around valve shaft rotation.Valve can be used for controlling air,
The flowing of the various types fluids such as water, steam, various corrosive medias, mud, oil product, liquid metal and radiating medium, In
Cutting and throttling action are mainly played on pipeline.Butterfly valve opening and closing element is a discoidal valve plate, around the axis of its own in valve body
Line rotation, to achieve the purpose that opening and closing or adjusting.There is many defects, such as sealing ring when reciprocating motion for existing butterfly valve
Distortion can be overturn, filler easily permeates, and does not have corrosion resistance, driving moment is big, and open and close speed is slower.Diesel exhaust gas system
It is gap-matched between the brake axle and lever of dynamic device exhaust butterfly valve, is then tightened with fastening bolt, driven by checking cylinder
Control stick control butterfly valve closes or opens, to reach braking purpose.But between being between use process exhaust brake axis and lever
Gap cooperation, is tightened, the relative rotation between brake axle and control stick inevitably occurs in use process, makes by fastening bolt
Gas butterfly valve in a row can not accurately close or open.
Utility model content
The utility model technical issues that need to address are to provide a kind of exhaust butterfly valve with operating stick, prevent use process
The middle relative rotation occurred between brake axle and control stick reduces brake axle institute so that exhaust butterfly valve accurately closes or opens
The machining accuracy needed reduces labor intensity, improves reliability.
In order to solve the above technical problems, the technical scheme adopted by the utility model is:
A kind of exhaust butterfly valve with operating stick, including valve body, the valve body top are fixedly connected with the platform with through-hole, institute
It states and is provided with valve plate on the inside of valve body, the valve plate is fixedly connected with brake axle, and brake axle passes through through-hole and extends to above platform, also
Including the control stick with the vertically disposed rolling brake axis of brake axle；Couple between control stick and brake axle for spline, brake axle
On be provided with spline, centre bore and the internal spline with spline fitted are provided on control stick；Control stick lower surface is provided with limit
Help plate, be arranged on platform with limit help plate to interference row at rotary stopper section limited block, the two of rotary stopper section
The corresponding exhaust butterfly valve opening in end is maximum and closes two states, and constantly valve plate is overlapped exhaust butterfly valve closure with valve body cross section, arranges
Valve plate and valve body longitudal section angle are 5 ° when the opening maximum of gas butterfly valve.
Technical solutions of the utility model further improvement lies in that: brake axle top is provided with rectangular slot, the side of fluting
To consistent with the extending direction of control stick.
Technical solutions of the utility model further improvement lies in that: valve plate and valve body longitudal section angle when exhaust butterfly valve closure
For position between angle be 85 ° or 95 °.
Technical solutions of the utility model further improvement lies in that: the spline is 13 millimeters long.
Technical solutions of the utility model further improvement lies in that: spline and internal spline are involute spline.
Technical solutions of the utility model further improvement lies in that: spline and internal spline are 32 spline structures.
By adopting the above-described technical solution, the technological progress that the utility model obtains is:
The connection between control stick and brake axle is strengthened by setting spline and internal spline, reaches accurate braking purpose,
The relative rotation occurred between brake axle and control stick in use process is prevented, so that exhaust butterfly valve is accurately closed or beaten
It opens.With spline instead of the fastening bolt of script connection is closed, it is strong to reduce labour for machining accuracy needed for reducing brake axle
Degree, improves reliability.
Brake axle top fluting facilitates operation when installation brake axle, is convenient for when installing brake axle to brake axle angle
It is controlled, is also convenient for adjusting the angle of brake axle, the direction of fluting and the extension side of control stick before control stick is not installed
To consistent, the angle between fluting and valve plate is regulated in advance, as long as guaranteeing fluting direction and behaviour when installing control stick
Vertical pole direction inhibits, and simplifies the installation process of control stick.
Angle facilitates the operating process of opening and closing valve plate between plane where control stick and valve plate, so that when opening and closing valve plate
Loading angle is more reasonable.Limited block and limit help plate effectively to control the rotational angle of operating stick, so that valve plate accurately in place, is prevented
The bad sealing of exhaust butterfly valve is stopped.The position of the position of valve plate and valve plate when exhaust butterfly valve closure when being vented the opening maximum of butterfly valve
The surface of valve plate is not parallel with fluid flow rate when angle between setting to be vented butterfly valve opening maximum for 85 ° or 95 °, is being arranged
Valve plate is not subject to excessive resistance when gas butterfly valve is closed, and facilitates the opening and closing of valve plate, while being also convenient for enabling and being vented butterfly valve
Enough adequately opening and closings.
