The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of no pod apertures plate valve that is adapted at arbitrarily angled installation, and is somebody's turn to do the favorable sealing property of no pod apertures plate valve.
To achieve these goals, the technical solution adopted in the utility model is: a kind of no pod apertures plate valve, comprise valve body, valve gap and valve seat, valve seat, valve gap are connected with valve seal respectively, be provided with valve rod in the valve gap, valve rod one end stretches into valve body and is provided with flashboard, valve gap is provided with and can drives the handwheel that flashboard rises or descends, it is characterized in that: described valve body both sides inwall is provided with the guide rail plate, the guide rail plate is provided with guide rail, described flashboard both sides are provided with the guide groove that is slidingly matched with described guide rail, also are provided with on the valve body to prevent that flashboard from departing from the limit stoper of guide rail.
In the said structure, the valve inner left and right sides is provided with the guide rail plate with guide rail, makes flashboard calculate its width and the degree of depth according to actual needs along the guide rail axial slip, guarantees that this guide groove in use can displacement, getaway; Guarantee the movement locus unanimity that flashboard opens and closes simultaneously, at same center line mobile and, and the setting of limit stoper can further prevent flashboard getaway in the process of motion.
As further setting of the present utility model, described limit stoper comprises the some roller bearings that are fixedly arranged on the described guide rail plate sidewall, described roller bearing is distributed in the guide rail both sides, and described flashboard is between the roller bearing of both sides, and flashboard cooperates with the roller bearing rolling along the guide rail direction.
In the said structure, roller bearing is fixed on the guide rail plate in the boring of the sidewall of guide rail plate and by fastening piece, the setting of roller bearing, flashboard can being limited on the one hand moves along the guide rail direction guarantees not getaway of flashboard simultaneously.
As further setting of the present utility model, offer the slot rolling that rolls and cooperate with described roller bearing on the described flashboard.
In the said structure, arranging of slot rolling can reduce the friction that flashboard moves up and down and brings, and simultaneously, can also alleviate the moment of torsion of valve opening and closing to a certain extent, makes switch valve lighter.
As further setting of the present utility model, described rail axis is parallel with the center line of described valve body.
In the said structure, rail axis is parallel with the valve body center line, makes that the movement locus of flashboard is also parallel with the center line of valve body, makes things convenient for the setting of guide rail plate and flashboard position.
Below in conjunction with accompanying drawing the utility model is further described.
