Abstract
The utility model relates to a high-performance assembled butterfly valve comprising a valve body, a valve seat, a valve rod, a valve cover assembly, a drive mechanism, a butterfly plate assembly and a lifting frame assembly, wherein one end of the valve rod penetrates through a valve cover to be connected with the drive mechanism, a valve rod translation operating mechanism is arranged on the valve body at the other end of the valve rod, the valve rod translation operating mechanism consists of a housing, a slantwise plate arranged in the housing, two triangular slantwise convex plates arranged at two sides of the slantwise plate, and two adjusting bolts respectively connected with the two triangular slantwise convex plates, and an installing hole movably matched with the valve rod is arranged in the middle of the slantwise plate. The two triangular slantwise convex plates arranged at two sides of the slantwise plate are adjusted by the adjusting bolts, so that the slantwise plate horizontally moves in the housing so as to drive the valve rod to horizontally move along with the axes direction of a liquid passageway, the butterfly plate is compacted with or separated from the valve seat, and the seal specific pressure of a seal surface between the butterfly plate and the valve seat is adjusted, therefore, the high-performance assembled butterfly valve has the advantages of being good in seal performance and convenient to install and maintain. The high-performance assembled butterfly valve is suitable for a plurality of control valves on various medium pipes.
Description
Technical field
The utility model relates to valve field, particularly about a kind of dress formula butterfly valve of going up.
Background technique
Last dress formula butterfly valve comprises that valve body, valve gap, valve rod, valve rod drive assembly, dish plate, and valve rod is perpendicular to medium circulating direction in the valve body, and become axial restraint with valve body, connection circumferentially is rotatably assorted; Valve gap is sheathed on outside the valve rod and is fixedly mounted on the valve body; The outer end of valve rod is stretched out valve gap and is installed on the valve rod driving assembly, and the dish plate is fixedly mounted on the valve rod by pin, and valve gap is installed on the valve body by bolt, nut; The dish plate can be packed into or takes out from valve gap together with valve rod, and installation, maintenance is convenient.To be the dish plate pack into behind the valve body together with valve rod its shortcoming, and the relative position between dish plate and the valve seat can not be adjusted, and can't regulate the seal pressure of dish plate and sealing surface of seat, poor sealing performance.
Summary of the invention
The purpose of the utility model is the shortcoming that exists to existing technology, and dress formula butterfly valve on a kind of high-performance of good seal performance is provided.
The technological scheme of the utility model comprises valve body, valve seat, valve rod, valve gap assembly, driving mechanism, dish plate assembly, suspension bracket assembly; One end of valve rod passes valve gap and is connected with driving mechanism; Mainly be on the valve body of the valve rod the other end, to be provided with valve rod translation mechanism; Said valve rod translation mechanism is made up of with the adjusting bolt that is connected two oblique flanges of triangle respectively a housing, the swash plate and two the oblique flanges of triangle of said swash plate both sides that are installed in the said housing, and the centre of said swash plate is shaped on the mounting hole that cooperates with valve handle activity.
In above technological scheme, said dish plate assembly is provided with the silica gel elastomeric seal circle that cooperatively interacts with valve seat.
The utility model has the advantages that and on valve body, be provided with valve rod translation mechanism; Through regulating two oblique flanges of triangle of bolt adjustment swash plate both sides; Make swash plate translation in housing, drive the translation of valve rod longshore current body passage axis direction, make butterfly plate compress valve seat or lift off a seat; Realize regulating the seal pressure of butterfly plate and sealing surface of seat, its good seal performance, installation and maintenance are conveniently.
