Abstract
The utility model discloses a butterfly valve with a device for preventing a taper pin from being flushed out. The butterfly valve comprises a valve plate (4), a valve shaft (1) and a taper pin (2), wherein a through hole which is adapted to the taper pin (2) is arranged at a corresponding position between the valve plate (4) and the valve shaft (1), and the taper pin (2) is arranged in the through hole, so that the valve plate (4) is integrally connected with the valve shaft (1). The butterfly valve is characterized by further comprising an internal hexagonal pointless set screw (3), the end at the through hole of the valve plate (4) is provided with a screw hole which is matched with the internal hexagonal pointless set screw (3), and the internal hexagonal pointless set screw (3) and the screw hole can axially position the taper pin (2). The butterfly valve has less parts, and is convenient to machine, thereby being low in machining cost and high in production efficiency. The taper pin can not become flexible, and a taper pin hole is blocked, so that the butterfly valve can not be leaked.
Description
Technical field
The utility model relates to butterfly valve, especially the valve plate of butterfly valve and valve shaft connection set.
Background technique
In recent years, the fast development of modernization industry made butterfly valve be widely used in advanced manufacturing process.Have spline to be connected for the butterfly plate and the Placement of valve shaft in the market and be connected, but these structures generally all can not satisfy the requirement of manufacturability, sealing and reliability simultaneously with pin.Therefore butterfly plate Placement in the market causes easily that processing cost height, efficient are low, poor sealing, butterfly plate produce drawbacks such as angle journey error and the easy inefficacy of link with valve shaft.
The model utility content
The purpose of this utility model is exactly to solve manufacturability, sealing and the integrity problem that butterfly plate is connected with valve shaft, makes finished product to reduce, improves sealing and reliability.
The technical solution adopted in the utility model is: the anti-butterfly valve of going out device of band taper pin, it comprises valve plate, valve shaft and taper pin, the corresponding position of valve plate and valve shaft is provided with the through hole adaptive with taper pin, taper pin is positioned at through hole to be connected as a single entity valve plate and valve shaft to realize being connected, it is characterized in that it also comprises interior hexagonal flush end Cock screw, the end of described valve plate through hole is provided with the screw that cooperates with interior hexagonal flush end Cock screw, and interior hexagonal flush end Cock screw connects with screw to be realized the taper pin axially locating.
Adopt technique scheme, because because of interior hexagonal flush end Cock screw applies tightening power to taper pin, so taper pin can not become flexible, and taper pin-hole does not connect simultaneously, thereby does not have leakage hidden danger.
In sum, the utility model beneficial effect is: the utility model can not produce leakage; Hexagonal flush end Cock screw directly applied tightening power to taper pin in the utility model adopted, no transition conduction mechanism, so tightening power is big, anti-loosing effect is good, has eliminated the leakage hidden danger of bindiny mechanism simultaneously fully.
