Description
Technical field
The utility model relates to a kind of gate valve, the gate valve that grow particularly a kind of wear-resisting service time.
Background technique
At present; The place that relates to FLUID TRANSPORTATION in cement plant and coal washery etc.; The general flow that uses gate valve to come fed sheet of a media in the controlling plumbing fixtures, gate valve has driving mechanism, flashboard and valve body, and driving mechanism can drive flashboard and move up and down sealed valve body; Be provided with two common wear-resisting circles block flashboard with formation cell body in the valve body; But because the cell body size is wayward between two common wear-resisting circles, friction is big relatively to the surface of contact of flashboard and two common wear-resisting circles for the medium of carrying in the pipeline, and therefore common wear-resisting circle is easy to wear causes gate valve shortening in working life.
The model utility content
The utility model problem to be solved provides a kind of wear-resisting gate valve of wear-resisting long service life, overcomes the problems referred to above of the prior art.
The utility model can solve through following technological scheme:
A kind of liner bulk ceramics wear-resistant sluice valve comprises driving mechanism, flashboard and valve body, and driving mechanism links to each other with flashboard; Valve body is provided with flashboard and inserts mouth, is provided with a bulk ceramics spare in the said valve body, and said valve body and bulk ceramics spare are respectively the hollow pipe shape; This bulk ceramics spare agrees with valve interior wall mutually; Said bulk ceramics spare is provided with the insertion groove that said flashboard inserts, and the insertion groove shape is identical with said flashboard shape, is provided with a seal ring between said insertion groove and the said flashboard; Be socketed with a baffle plate in the said ceramic fitting, this baffle plate one end is socketed in the said ceramic fitting, and the outside is fitted in the ceramic fitting outside.
The Sealing of stating is a wear-resisting polyamine fat mould pressing structure.
Said valve body and bulk ceramics spare are the hollow cylindrical of straight-through type.
Said flashboard and said insertion groove are respectively rectangular.
Said flashboard and said insertion groove are respectively circular arc.
Said valve body is provided with valve gap, and said flashboard inserts mouth and is located on this valve gap.
Said bulk ceramics spare is that mould is made integrated member, and said bulk ceramics spare material is the 96-97 ceramic alumina.
Because adopt above technological scheme, a kind of liner bulk ceramics wear-resistant sluice valve of the utility model is equipped with a bulk ceramics spare in this gate valve; And this bulk ceramics spare is provided with the insertion groove that flashboard inserts; Simultaneously the ceramic fitting outside is provided with the plate washer that shields, and the ceramic fitting in it is played a protective role, and when making this bulk ceramics spare, can confirm the size of insertion groove according to flashboard; Therefore reduced of the friction of the medium of conveying in the pipeline to bulk ceramics spare; Improved the working life of gate valve, be provided with a Sealing between flashboard and the insertion groove simultaneously, whole device has been played the seal protection effect.

Embodiment
Below in conjunction with embodiment, further set forth the utility model:
As shown in Figure 1, the utility model liner bulk ceramics wear-resistant sluice valve comprises driving mechanism 1, flashboard 2 and valve body 3; Driving mechanism 1 links to each other with flashboard 2, and valve body 3 is provided with flashboard and inserts mouth, is provided with a bulk ceramics spare 4 (seeing shown in Fig. 3-4) in the valve body; Valve body and bulk ceramics spare 4 is respectively pipe-like, and this bulk ceramics spare 4 agrees with valve interior wall mutually, and bulk ceramics spare 4 is provided with the insertion groove 5 that flashboard 2 inserts; The insertion groove shape is identical with the flashboard shape, makes flashboard 2 better sealed valve bodies.Flashboard 2 can adopt the import wearing plate, improves the wear resistance of flashboard.
Be provided with a seal ring 8 between insertion groove 5 and the flashboard 2, can be through sealing circle 8 to playing good seal action between insertion groove 5 and the flashboard 2, as shown in Figure 5, it is the structural representation of the Sealing 8 of the utility model; Be socketed with a baffle plate 7 in the ceramic fitting 4, these baffle plate 7 one ends are socketed in the ceramic fitting 4, and the outside is fitted in ceramic fitting 4 outsides, can play a protective role to ceramic fitting 4, prevent in the using process, and rubble damages ceramic fitting 4.
As shown in Figure 4, when flashboard 2 was the circular arc flashboard, the insertion groove 5 on the bulk ceramics spare 4 had corresponding circular arc, made flashboard 2 better sealed valve bodies.
Can be provided with valve gap 6 on the valve body 3, offer above-mentioned flashboard on the valve gap 6 and insert mouth, bulk ceramics spare is formed through the mould manufacturing by 96-97 ceramic alumina material.
This gate valve only needs driving driving mechanism 1 just can drive lock 2 and is inserted in the insertion groove 5 on the bulk ceramics spare 4 through valve body upper flashboard 2 insertion mouths in use, and sealed valve body 3 also can be extracted valve body 3 out at the following flashboard 2 of the drive of driving mechanism and make the valve body conducting.In sealing or open in valve body 3 processes, because bulk ceramics spare 4 is a single piece and by the size of the good insertion groove of size design of flashboard 2, so the medium of carrying in the pipeline reduces the degree of friction of bulk ceramics spare 4, and this gate valve is increased working life.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
