Description
Technical field
The utility model relates to valve field, is specifically related to a kind of ore pulp valve.
Background technique
Ore pulp valve is generally used for conveying containing in the pipeline of solid particle medium.Existing ore pulp valve is many to be made up of three pieces type structure, to be coordinated form elastic packing by flashboard with the seal ring of its both sides.
But, when valve is in full-gear, two seal rings can not form sealing, there is gap between two seal rings, medium can enter in valve pocket by this gap, and accumulating in valve pocket, the medium containing solid particle can cover on the sealing surface and flashboard of seal ring, can affect the sealability of valve like this, and in Long-Time Service process, solid particle rubs between flashboard and seal ring, easily destroys the sealability of sealing surface, causes leaking.
And existing ore pulp valve can not realize on-line maintenance, its maintenance must close whole medium circulation tube road, have impact on the progress of work, and maintenance also bothers.
Model utility content
The purpose of this utility model is to provide a kind of favorable sealing property, and can the ore pulp valve of on-line maintenance.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of ore pulp valve, comprise valve body, be arranged at two seal rings of the valve body left and right sides, be arranged at valve body upper end and flashboard, the filler being arranged at valve body upper end open place and the Gland that can move up and down, described flashboard can stretch into coordinate with seal ring between two seal rings and form elastic packing, described seal ring is made up of rubber material, it is characterized in that: two described seal ring elastic packings coordinate, the madial wall of described seal ring is provided with elastic compensating groove, and described elastic compensating groove is the annular groove coaxial with seal ring.
The utility model is also set to further, and described seal ring is made up of abrasive rubber material.
The utility model is also set to further, is provided with metal joist in described seal ring.
The utility model is also set to further, and described elastic compensating groove is provided with 1-5 bar.
The utility model is also set to further, and described filler becomes tooth Shape Design with the surface of contact of flashboard, and this tooth-shape structure can along ram movement direction scraping flashboard.
The utility model is also set to further, and described filler is made up of rubber material.
The utility model is also set to further, the grease storage groove that described valve body upper end is also provided with greasing hole and is communicated with greasing hole, and described grease storage groove is communicated with the sealing surface that flashboard coordinates with seal ring.
The beneficial effects of the utility model:
(1) the utility model provide two of ore pulp valve seal rings can be formed under the effect of its own resilient elastic packing coordinate, when valve is in any open position, two seal rings can form sealing, that has stopped that medium enters that valve pocket contacts with other component may, effectively prevent medium washing away valve body and other component, substantially increase the working life of valve, improve the sealability of valve.Meanwhile, when valve is in full-gear, two seal rings are formed and are sealed and matched, and flashboard is positioned at above seal ring, and user can change other component such as flashboard online;
(2) filler becomes tooth Shape Design with the surface of contact of flashboard, and this tooth-shape structure along ram movement direction scraping flashboard, effectively can strike off the impurity on flashboard, reduce the friction of filler and flashboard, thus effectively reduce the moment of torsion of valve, improve valve seal performance.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Below with reference to Fig. 1 to Fig. 3, the utility model is described.
A kind of ore pulp valve, comprise valve body 1, be arranged at two seal rings 2 of valve body 1 left and right sides, be arranged at valve body 1 upper end and flashboard 3, the filler 4 being arranged at valve body 1 upper end open place and the Gland 5 that can move up and down, described flashboard 3 can stretch into coordinate with seal ring 2 between two seal rings 2 and form elastic packing, and described seal ring 2 is made up of rubber material.Valve body 1 is straight-through type, and two seal rings 2 are placed in the import and export of valve body 1 left and right sides respectively, and seal ring 2 is fixed on valve body 1 by the flange coordinated with valve body 1, does not need other fastening pieces, is convenient to replacing and the maintenance of seal ring 2.Vertical passage is provided with in the middle of valve body 1, this passage moves for flashboard 3, flashboard 3 enters in valve body 1 from the upper end open of valve body 1, and elastic packing can be formed with seal ring 2, the upper end open place of valve body 1 is provided with filler 4, this filler 4 for the opening of shutoff valve body 1 upper end, and is fixed by Gland 5 pairs of fillers 4.
Two seal ring 2 elastic packings coordinate, the opposite sides of seal ring 2 offsets to coordinate and forms sealing, opposite side and fastening flange offset, because seal ring 2 is made up of rubber material, itself there is certain elasticity, two seal rings 2 offseted can form elastic packing under the effect of himself elastic force, and seal ring 2 also can adopt other elastic material manufactures.The elastic packing formed to make two seal rings 2 self is stable, reliable, the madial wall of seal ring 2 is provided with elastic compensating groove 6, described elastic compensating groove 6 is the annular groove coaxial with seal ring 2, this elastic compensating groove 6 can make seal ring 2 not produce drastic deformation and damage when being squeezed and medium tears, effectively ensure that the sealability of seal ring 2, meanwhile, elastic compensating groove 6 also can strengthen two resilient sealing force offseted between seal ring 2.
Two seal rings 2 coordinate owing to self can form elastic packing, so, when valve is in full-gear, flashboard 3 is placed in above seal ring 2, two seal rings 2 can form sealing, stopped that medium enters that valve pocket contacts with other component may, user can change other component such as flashboard 3 grade online.
Seal ring 2 is made up of abrasive rubber material, and the seal ring 2 that this material is made can stand the friction with flashboard 3 of washing away of medium for a long time, has longer working life.
Be provided with metal joist in seal ring 2, effectively can improve mechanical property and the intensity of seal ring 2.
Elastic compensating groove 6 can be provided with many, and the present embodiment accompanying drawing Elastic compensating tank 6 is provided with 5, during actual job, can select the number of elastic compensating groove 6 according to the difference of valve aperture.
Filler 4 becomes tooth Shape Design with the surface of contact of flashboard 3, this tooth-shape structure can along flashboard 3 moving direction scraping flashboard 3, described filler 4 is made up of rubber material, filler 4 effectively can strike off the impurity on flashboard 3, reduce the friction of filler 4 and flashboard 3, thus effectively reduce the moment of torsion of valve, improve valve seal performance.
The grease storage groove 8 that valve body 1 upper end is also provided with greasing hole 7 and is communicated with greasing hole 7, grease storage groove 8 is opened on the sidewall of valve body 1 center-aisle, described grease storage groove 8 is communicated with the sealing surface that flashboard 3 coordinates with seal ring 2, and the lubricating grease be convenient in grease storage groove 8 lubricates flashboard 3.
The above is only preferred implementation of the present utility model; should be understood that; time in those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection domain of the present utility model.
