Abstract
The utility model relates to a bidirectional-pressure all-metal reed type butterfly valve which comprises a butterfly plate, a valve rod, a valve body and a lifting ring, wherein the valve rod is fixedly connected with the butterfly plate arranged inside the valve body, a seal ring is fixedly installed on one side of the butterfly plate through a fastening screw, a reed type U-shaped movable valve base is arranged on one side of the seal ring and arranged inside the valve body, the lifting ring is arranged on the other side of the reed type U-shaped movable valve base and is fixedly connected with the lifting ring through a connecting screw, an elastic boss is arranged on the internal diameter of the reed type U-shaped movable valve base, the internal diameter end face of the elastic boss is matched with the external diameter end face of the seal ring in a sealed mode to form a sealing pair, a U-shaped groove is formed in the elastic boss, the opening of the U-shaped groove faces towards the lifting ring, a plurality of adjusting screws are arranged on the lifting ring, and lower ends of the adjusting screws penetrate through the lifting ring to make contact with the elastic boss. According to the bidirectional-pressure all-metal reed type butterfly valve, the structure is simple, extrusion to the U-shaped groove of the elastic boss is achieved through the adjusting screws to enable the U-shaped groove to be completely attached to the seal ring, therefore the bidirectional sealing effect is achieved, and the service life of the bidirectional-pressure all-metal reed type butterfly valve is prolonged.
Description
Technical field
The utility model relates to Bidirectional pressure full-metallic reed-type butterfly valve, belongs to butterfly valve technical field.
Background technique
The valve seat of existing butterfly valve hard sealing structure is in valve body, thereby the seal pressure of realizing sealing pair by adjusting the pad at the valve seat back side reaches sealing effect, but this structure is with certain narrow limitation, accumulation because of various machining tolerances in production process causes assembling difficulty to increase, efficiency is low, because the difference in torque distance of the larger generation like products of adjustment difficulty is larger, sealing pair is short working life, is difficult to reach two way sealed effect.
Model utility content
For above-mentioned defect, it is a kind of simple in structure that the purpose of this utility model is to provide, and without carrying out the adjustment of valve seat pad, can to realize like products moment of torsion identical, increases sealing pair working life, realizes the Bidirectional pressure full-metallic reed-type butterfly valve of two way sealed effect.
The technological scheme that the utility model adopts is for this reason: comprise butterfly plate, valve rod, valve body and suspension ring, described valve rod is fixedly connected with the butterfly plate in being built in valve body, one side of butterfly plate is installed with seal ring by fastening screw trip bolt, one side of described seal ring is provided with the U-shaped movable valve seat of reed-type and is built in valve body, the U-shaped movable valve seat opposite side of reed-type is provided with suspension ring and is fixedly connected with it by attachment screw, the internal diameter of the U-shaped movable valve seat of described reed-type is provided with elasticity boss, the internal diameter end face of elasticity boss coordinates formation sealing pair with the external diameter end face seal of seal ring, described elasticity boss is provided with U-shaped groove, the opening of described U-shaped groove is towards suspension ring, suspension ring are provided with some adjusting screw, described adjusting screw lower end contacts with elasticity boss through suspension ring.
Between described butterfly plate and seal ring, be provided with gasket seal.
In described valve body, be provided with step, the U-shaped movable valve seat of described reed-type is stuck in step place, the step place of described valve body and the U-shaped movable valve seat of reed-type axially between be provided with pad.
The utility model has the advantages that: the utility model is simple in structure, by adjusting screw, realize the laminating completely that the extruding of the U-shaped groove of elasticity boss is made to itself and seal ring, thereby realize two way sealed effect; The utility model has saved the adjustment process in production process, makes the standardization of product moment of torsion, thereby greatly increases the working life of product, and has saved and assembled the required plenty of time, has improved product performance.
Accompanying drawing explanation
