Abstract
The sliding-plug split-type exhaust valve with a limiting device comprises a housing, wherein the housing is composed of an upper part and a lower part; the upper housing and the lower housing are connected by a flange; the valve body is mounted on the upper housing; a valve plug is mounted in the valve chamber of the valve body; a rigid straight connecting rod is connected to the rear end of the valve plug; a floating ball is connected to the other end of the rigid straight connecting rod, wherein an annular limiting ring is arranged at the joint of the upper and lower housings in the housing; a cone is arranged at the lower part of the floating ball; the annular limiting ring limits the cone from rising; and the annular limiting ring and the cone on the floating ball form a floating ball limiting device. The annular horizontal limiting structure of the sliding-plug split-type exhaust valve is capable of thoroughly guaranteeing the accuracy of limitation; and the limiting device is made of a non-metallic material, and thereby may not rust to cause limiting failure and floating ball adhesion; therefore, the quality and service life of the product are guaranteed.
Description
Technical field
The utility model belongs to automatic exhaust valve.
Background technique
The valve body that sliding plug is broken the formula exhaust steam valve into two with one's hands is fixed on housing top; Valve plug is installed in the valve pocket of valve body; The connecting rod of valve plug rear end stretches out with ball float from the valve pocket rear portion and is connected, and is moved by ball float drivening rod upper and lower to make valve plug be adjacent to and break into two with one's hands to valve port to realize closing and opening of valve, owing to reduced the stroke of valve plug; Thereby reduced the volume of valve body effectively; But the status requirement to ball float during this structure valve plug close port is very strict, requires the position of ball float will guarantee that connecting rod is in level, and at this moment the valve plug power that is applied to valve port is in maximum.Present this exhaust steam valve all be with above the valve chest inwall as confined planes; Connecting rod was in level when ball float pushed up above the inner walls; But metal valve body especially irony housing can be got rusty for a long time, the one, and confined planes is moved down, make connecting rod be in the declivity state; The power of closing reduces, and exhaust steam valve leaks; The 2nd, can cause ball float grotesque peak portion and the adhesion above the inner walls, valve is not opened malfunctioning.
Summary of the invention
The purpose of the utility model is to provide a kind of sliding plug with stopper to break the formula exhaust steam valve into two with one's hands, and the technological scheme of the utility model comprises a housing shown in accompanying drawing; Housing is made up of upper and lower two-part, and the upper and lower casing flange connects, and valve body is installed in upper shell; Valve plug is installed in the valve pocket of valve body, and the valve plug rear end connects a rigidity vertical bar connecting rod, and the rigidity vertical bar connecting rod the other end connects ball float; There is an annular stop circle lower shell body joint on it is characterized in that in housing; A round platform is arranged at the ball float bottom, and the annular stop circle limits the up of round platform, and the round platform on annular stop circle and the ball float constitutes the ball float limit stoper.The annular horizontal limit structure of the utility model can fully guarantee spacing accuracy, and limit stoper processed by nonmetallic material, can not get rusty and cause spacing error and ball float adhesion, thereby guarantee the quality and the working life of product.
The position limit cycle of the utility model can be the inside prolongation of upper and lower casing sealing gasket, shown in accompanying drawing 1, also can be that mounting groove is made in upper and lower casing sealing gasket inboard, embeds the annular stop ring at mounting groove, constitutes position limit cycle, shown in accompanying drawing 2.
Description of drawings
Accompanying drawing 1 is one of the utility model plan view, and the upper and lower casing sealing gasket inwardly prolongs as position limit cycle among the figure.
Accompanying drawing 2 is two of the utility model plan view, and the mounting groove at the upper and lower casing sealing gasket among the figure is embedded in limited ring as position limit cycle.
Legend: 1, valve plug, 2, connecting rod, 3, ball float.4, sealing gasket, 5, fulcrum, 6, ball float bottom round platform, 7, limited ring.
Embodiment
One, the exhaust steam valve housing is made up of upper shell and lower shell body, and the upper and lower casing flange connects, and valve body is fixed on upper shell top; Valve pocket is a cylindrical cavity; Valve plug is installed in the valve pocket of valve body, the fixing vertical bar connecting rod of processing by steel wire in valve plug rear end, and the front end of rigidity vertical bar connecting rod is connected with ball float.A round platform is arranged at the ball float bottom, and the upper and lower casing rubber gasket is directly made position limit cycle, and the bottom side of position limit cycle is uniformly distributed with a plurality of fulcrums, to prevent round platform and position limit cycle adhesion.
Two, to make groove be mounting groove in upper and lower casing rubber gasket inboard, and the plastics limited ring is installed in the groove, and the bottom side of plastics limited ring is uniformly distributed with six fulcrums.Other are with embodiment one.
