Description
Technical field
The present invention relates to a kind of valve, especially relate to a kind of gate valve for slurry that is mainly used in paper making pulp.
Background technique
Gate valve for slurry is a kind of valve commonly used that is used for paper making pulp, and is not enough below the existing gate valve for slurry ubiquity:
1) runner has groove, is prone to store foreign matter, influences valve plate and opens and closes, and causes leakage.
2) when valve opening, sealing surface of seat directly receives fluid scouring, and is fragile.
3) conventional knives packing of gate valve and valve plate surface of contact are big, and frictional force is bigger, and the steering force of handwheel is big, and keying is wasted time and energy.
4) life cycle is short, and safeguarding frequently increases cost of production.
Summary of the invention
The object of the present invention is to provide a kind of improved gate valve for slurry that is mainly used in paper making pulp.
The present invention is provided with knife plate (flashboard), valve body, valve gap, filler, Gland, valve rod (axle), axle sleeve and handwheel; Be fixedly connected between said valve body and the valve gap, knife plate (flashboard) is installed in valve body and valve gap inner chamber, and the motion of knife plate (flashboard) is driven by valve rod (axle), and the movement locus of knife plate (flashboard) is confirmed by the guiding groove in the valve body; Hinge is connected between valve rod (axle) and the knife plate (flashboard); Valve rod (axle) is provided with fluting, and knife plate (flashboard) inserts in the fluting, and valve gap is provided with the valve gap stuffing box; Fill filler in the said valve gap stuffing box and compress by Gland; Valve rod (axle) passes valve gap stuffing box and Gland, and axle sleeve is installed on the valve gap, and axle sleeve and valve rod (axle) constitute T shape screw-thread fit and be fixed on the valve gap; Handwheel is installed in valve rod (axle) top.
Can be fixedly connected through stud between said valve body and the valve gap.
Said valve body and valve gap can be by middle flange gasket sealings.
Can be provided with seal ring in the sealing surface groove of said valve body.
An available latch is connected between said valve rod (axle) and the knife plate (flashboard).
Can adopt between said Gland and the valve gap and be threaded.
Can be provided with the Gland groove in the said Gland, can be provided with dust ring in the said Gland groove, preventing dust encloses the dust sealing effect.
The bottom of the valve gap stuffing box of said valve gap can be provided with bottom groove, can be provided with seal ring in the said bottom groove, and seal ring seals.
Said handwheel is installed in valve rod (axle) top and fixes with the nut check of band dust cover.
Knife plate of the present invention and the lining seal ring in the valve body sealing surface groove is formed sealing configuration, and knife plate is a valve opening and closing element.In addition, filler, Gland, dust ring and seal ring are formed the sealing configuration between valve rod and the valve body, guarantee the sealing between valve rod and the valve body.Simultaneously, handwheel rotating band ovable valve stem is done elevating movement, thereby drives the knife plate motion, realizes the valve switch effect.
Compare with existing gate valve for slurry, the present invention has following outstanding advantage:
1) product structure design is the super-short one-way sealing, and it has compact structure, advantages such as cost of material are installed, effectively reduced in little, in light weight, the convenient transportation of volume.
2) currency structure is designed to straight-through type does not have groove, has solved domestic and international existing defeated row's paper pulp valve circulation road groove is arranged, has been prone to glue, has been prone to scab, has been prone to serious problems such as G-card material.
3) the sealing surface of seat design is avoided washing away with circulation road flowing medium generation front and damaging sealing surface to guarantee realization in stowed position, improves the sealing grade, the life cycle that prolongs seal valve seat.
4) seal valve seat is based on the particularity of medium, and sealing surface of seat is designed to be prone to install quick detachable removable sealing configuration.
5) sealing ring material of quick detachable replaceable valve seat can be selected antiscour, nanometer sculpturing glue composite material such as wear-resistant, anticorrosive, high temperature resistant, anti-aging for use.
6) do not have stuffing box packing, no Gland around flashboard is designed to, the flashboard that comprehensively changes the traditional gate valve for slurry of elimination receives the gravity of stuffing box packing all around to surround the life cycle that friction prolongs lifting flashboard and restrictor bar, alleviates saving labor intensity, the saving cost.
