As a kind of improvement of the present utility model, described connector is triangular in shape, one base angle of described triangle connector is fixing with the first flashboard to be connected, and another base angle is fixing with the second flashboard to be connected, and the drift angle of described triangle connector and the second flashboard are flexibly connected.
As further improvement of the utility model, the drift angle of described triangle connector is located on the second flashboard and coordinates with the second flashboard sliding.
As further improvement of the utility model, the drift angle of described triangle connector is located at the lower section at two base angles of triangle connector.
As further improvement of the utility model, described first flashboard and the second flashboard fit and form inverted v-seal face.
As further improvement of the utility model, the end face of described second flashboard outwards folds edge, and described edge is buckled on the outer wall of valve body media passage.
As further improvement of the utility model, described valve body is provided with groove, and described valve gap is provided with the annular lug inserted in valve body recess.
As further improvement of the utility model, in described groove, it is provided with pad.
As further improvement of the utility model, described valve seat is provided with greasing hole.
The beneficial effects of the utility model are, during valve opening and closing, are in disengaged position between flashboard assembly and valve seat all the time, reduce the friction that flashboard assembly is secondary with valve base sealing, have abrasion little, the feature of good seal performance；Flashboard assembly is inclined-plane expanding structure, belongs to forced seal, can realize at low pressures reliably sealing；Second flashboard is connected by connector, and under the effect of connector, valve moment in running is little.This utility model also has rational in infrastructure, seals reliable, operates light, anticorrosion, wear-resisting, erosion resistance, service life the advantage such as length.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
As shown in Figure 1, a kind of metal hard-sealing double disc flat gate valves, including valve body 1, valve gap 2, support 3, valve rod 4, flashboard assembly 5, valve seat 6 and drive mechanism 7, it is provided with medium channel 11 in described valve body 1, described drive mechanism 7 is connected with flashboard assembly 5 by valve rod 4, match with valve seat 6 when described flashboard assembly 5 has installation and cut off the primary importance of medium channel 11 and driven the second position that medium channel 11 is turned on by drive mechanism 7, described flashboard assembly 5 includes the first flashboard 51 and the second flashboard 52, described valve rod 4 is fixing with the first flashboard 51 to be connected, the first described flashboard 51 is connected with the second flashboard 52 by connector 8.The beneficial effects of the utility model are, during valve opening and closing, are in disengaged position between flashboard assembly and valve seat all the time, reduce the friction that flashboard assembly is secondary with valve base sealing, have abrasion little, the feature of good seal performance；Flashboard assembly is inclined-plane expanding structure, belongs to forced seal, can realize at low pressures reliably sealing；Second flashboard is connected by connector, and under the effect of connector, valve moment in running is little.This utility model also has rational in infrastructure, seals reliable, operates light, anticorrosion, wear-resisting, erosion resistance, service life the advantage such as length.
Described connector 8 is triangular in shape, and a base angle of described triangle connector 8 is fixing with the first flashboard 51 to be connected, and another base angle is fixing with the second flashboard 52 to be connected, and drift angle and second flashboard 52 of described triangle connector 8 are flexibly connected.Specifically, the drift angle of described triangle connector 8 is located on the second flashboard 52 and coordinates with the second flashboard 52 sliding.In particular, the drift angle of described triangle connector 8 is located at the lower section at 8 two base angles of triangle connector (referring to accompanying drawing 1, below relate to orientation all referring to accompanying drawing 1).When valve rod rises, the first flashboard is driven to synchronize to rise, now, it is separately fixed on first, second flashboard due to two base angles of connector and the drift angle of connector and the second flashboard sliding coordinate, therefore, the sliding on the second flashboard of the drift angle of connector, and drive the second flashboard to rise after sliding puts in place so that medium channel turns on；When valve rod falls, first, second flashboard synchronizes, and after the second flashboard puts in place, valve rod continues to move downward, now stem depression the first flashboard, and the first flashboard makes the drift angle sliding to the right of connector, it is achieved forced seal.It is reliable that such structure makes product seal, good seal performance, is particularly suitable for realizing at low pressures reliably sealing.
Described first flashboard 51 and the second flashboard 52 fit and form inverted v-seal face 53.It is reliable that such structure makes product seal.
The end face of described second flashboard 52 outwards folds edge 521, and described edge 521 is buckled on the outer wall of valve body 1 medium channel 11.The motion of the second flashboard can be carried out spacing by the structure at edge, it is to avoid motion crossed by the second flashboard, ram seal can be made reliable simultaneously.
Described valve body 1 is provided with groove 12, and described valve gap 2 is provided with the annular lug 21 inserted in valve body 1 groove 12.In particular, it is provided with pad 121 in described groove 12.Annular lug and the setting of groove make product seal reliable at valve gap and provide spacing so that product is easy for installation.The setting of pad is further ensured that the sealing property of product.
Described valve seat 6 is provided with greasing hole 61.Valve seat and flashboard assembly can be lubricated by arranging of greasing hole, are also provided that emergency sealing, the security performance of improving product when black box lost efficacy.
Every technical staff's notice: although this utility model describes according to above-mentioned detailed description of the invention; but invention thought of the present utility model is not limited to that utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
