Technical Field
The utility model relates to a disk seat especially relates to a valve disk seat with adjustable.
Background
A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a closing member (a valve clack or a butterfly plate) is a disk. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved.
Ball valve, the open-close piece (ball) is driven by the valve rod and rotates around the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline.
No matter butterfly valve or ball valve all include valve body, disk seat and rings, and current disk seat fixed mounting is inside the valve body, and in the long-time use, the disk seat can take place wearing and tearing, disk seat and opening and closing member contact failure, greatly reduced sealed effect, and need dismantle when current disk seat is adjusted, adjust and get up the trouble.
SUMMERY OF THE UTILITY MODEL
To the above defect, the utility model aims to provide a simple structure can adjust valve disk seat position, guarantees the adjustable valve disk seat of sealed effect.
Therefore, the utility model adopts the technical proposal that:
including valve body, disk seat and rings, the disk seat is installed inside the feed liquor end of valve body, the inside annular ka tai that is equipped with of valve body feed liquor end, disk seat inner is equipped with annular step, annular step card is in annular ka tai department, the inside annular groove that is equipped with of feed liquor end of valve body, rings are located the disk seat outside, be equipped with annular boss on the outer circumference of rings, annular boss is located annular groove, the outer terminal surface of rings is equipped with a plurality of countersunk head unthreaded holes that are located on same circumference, be equipped with connecting bolt in the countersunk head unthreaded hole, the outer terminal surface of disk seat is equipped with a plurality of and connecting bolt matched with screw holes, the outer terminal surface of rings is equipped with a plurality of countersunk head screw holes that are located on same circumference, countersunk head threaded hole is equipped with adjusting bolt, adjusting bolt's screw.
