Description
Technical field
This utility model relates to a kind of butterfly valve, is specifically related to the flange form butterfly valve of a kind of band spacer pin.
Background technology
Butterfly valve is again flap valve, it it is the regulation valve of a kind of simple in construction, the butterfly valve of the on-off control that can be used for low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, rotate a kind of valve reaching to open and close around valve shaft, valve can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Pipeline acts primarily as cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, and in valve body, the axis around himself rotates, thus reaches to open and close or the purpose of regulation.The unlatching of butterfly valve is generally realized by handwheel or spanner rotation valve rod, in actual use, easily opens by mistake butterfly valve by mistake, bring unnecessary consequence when personnel encounter handwheel.
Summary of the invention
The purpose of this utility model is to provide the flange form butterfly valve of a kind of band spacer pin preventing maloperation.
The technical scheme that this utility model is taked is: the flange form butterfly valve of a kind of band spacer pin, including valve body, the both sides of valve body are provided with charging and discharging mouth, spool is installed in valve body, the top of spool is provided with valve rod, and valve rod stretches out in the valve rod hole of body top, is filled with filler in valve rod hole, the top of valve rod hole is provided with gland, and the edge of described gland is provided with a circle spacing hole；Spacing spanner is installed on the external part of valve rod, described spacing spanner includes spanner, ripping bar and spring catch, spanner be arranged in parallel with ripping bar, the end face of the head of described spanner is provided with fulcrum, ripping bar is polyline shaped, ripping bar leading portion is set in parallel in above spanner, ripping bar transfers downwards to tilt to extend to the lower section of spanner from stage casing, ripping bar head is supported in the fulcrum of spanner, coordinate with spacing hole after spring catch cross-under ripping bar and spanner the most successively, the fixing seat of spring catch is installed on spanner, and the top of spring catch telescopic end is spacing with ripping bar end face through draw ring.
After taking above technical scheme, the fulcrum on ripping bar, spanner and spanner is utilized to form lever, ripping bar is not provided with hole, spanner passes in scissor-shaped in hole, and ripping bar is that broken line turns, and ripping bar front end is positioned at above spanner, back segment is positioned at below spanner, hold ripping bar at the same time and spanner afterbody is, drive spring catch pull up or insert spacing hole, complete to release or spacing；This limit method only needs one-handed performance, easy to operate, effectively prevents maloperation.
