Abstract

The utility model discloses a cutter sluice valve, which is characterized in that a sealed seat and a gland strip are arranged between a left and a right valve body plates, and a sluice plate is connected with a valve stem via a pin shaft. Since the sealed seat and the gland strip are arranged between the left and the right valve body plates of the utility model, the planes of the sealed seat and the gland strip matched with the left and the right valve body plates, the utility model can be sealed via the pressure of a medium, and the sealed specific pressure generated by the planes is larger with the increase of the pressure of the medium. The nominal pressure of the valve is increased, sealing performance is enhanced, and the requirements of users are satisfied. The bottom of the sealed seat adopts a structure with a round bottom and an inclined plane, the bottom of the sluice valve can not accumulate residues, integral structure is compact, and self-centering effect is obtained for the sluice plate.

Description

A kind of disconnecting link valve

Technical field:

The utility model relates to the technical field of valve, specifically a kind of disconnecting link valve with plane sealing structure.

Background technique:

The disconnecting link valve is widely used in chemical industry, papermaking, the mobile occasion of sewage treatment pipeline control media, and it is big that present of home make disconnecting link valve ubiquity open and close torque, and nominal pressure is low, and particularly under the big situation of pressure medium, its seal degree is relatively poor.

Summary of the invention:

The purpose of this utility model is to provide a kind of improved disconnecting link valve, and it can improve seal pressure and nominal pressure under the situation that pressure medium improves.

The technical solution of the utility model is achieved in that a kind of disconnecting link valve, it mainly comprises left and right valve body plate, be contained in the flashboard in the left and right valve body plate, the flashboard that is connected with valve rod, outside at valve rod is provided with panel, it is characterized in that: between left and right valve body plate sealing seat and Stamping Steel Ribbon are housed, flashboard is connected with valve rod by bearing pin.

The utility model is owing to be equipped with sealing seat and Stamping Steel Ribbon between left and right valve body plate, and sealing seat and Stamping Steel Ribbon plane sealing for matching with left and right valve body plate, it can rely on the pressure of medium to seal, and can be along with the raising of pressure medium, the seal pressure that its plane produced is big more, the nominal pressure of valve is improved, improved sealability, satisfied user's demand, and the structure on round bottom inclined-plane has been adopted in the bottom surface of sealing seat, not only the bottom of gate valve can accumulated slag, compact overall structure, and flashboard also has self centering effect.
