Description
Technical field
The utility model relates to a kind of gate valve, particularly the split type flashboard of a kind of wedge shape of gate valve.
Background technique
Wedge action valve is that between a kind of flashboard and valve inner valve seat, junction plane is the valve body of wedge shape, and it is widely used in the fields such as electric power, oil, chemical industry.
Traditional wedge action valve is primarily of valve body, the valve seat be located in valve body, the driving mechanism that is elevated along valve body with salable wedge shape valve plate, the valve rod of the wedge shape that links valve plate and the actuate valve stem coordinated of valve seat.Usually, wedge shape flashboard is divided into two kinds, and one is two shoe brake plate compositions, conflicted by spring between two flashboards, realize the sealing between valve seat, but the easily passing in time and eliminating gradually of the elastic force of spring, cause the sealing between flashboard and valve seat to occur unstable situation; It two is integrated type flashboard, and adopt hard to seal between this type of flashboard and valve seat, after sealing surface weares and teares, flashboard does not have elastomeric expansion to conflict, and valve body also can be caused to occur leaking.
Summary of the invention
For the deficiency that prior art exists, the utility model provides the split type flashboard of wedge shape of a kind of good airproof performance, the simple gate valve of structure.
For achieving the above object, the utility model provides following technological scheme: a kind of split type flashboard of wedge shape of gate valve, it is characterized in that: include top seal part and the lower sealing portion hinged with top seal part, top seal part includes gate panel body, sealing place of gate panel body is provided with elastic hard Sealing, lower sealing portion includes two pieces can the lower rams of opening and closing, the other end place that two lower part flashboards splice one end is relatively respectively equipped with Sealing, hinged by hinging shaft between two lower rams and gate panel body, two lower rams offer installation cavity relative to the other end place being connected one end with gate panel body, expansion sleeve is provided with in installation cavity, at least lack one in expansion sleeve and cavity volume is installed, be provided with in the installation cavity volume of expansion sleeve and the elasticity collision piece of installing cavity volume sidewall and conflicting, this elasticity collision piece is be arranged in the elastic collar with opening installed in cavity volume.
Adopt technique scheme, flashboard is set to top seal part and lower sealing portion, make the top and the bottom of the flashboard Packed function of tool respectively, make the valve seat place of valve body have double seal, ensure that the sealing of valve body; If the setting of elastic hard Sealing makes the valve seat of gate panel body and valve body conflict to implement to occur that wearing and tearing there will not be leakage when sealing, ensure that the sealing sealed herein on gate panel body; The setting of the expansion sleeve between two lower rams in installation cavity can be implemented to control to the opening and closing of two lower rams, what drive expansion sleeve to expand is then that it installs the elastic collar arranged in cavity volume, elastic collar is adopted to be because elastic collar is cheap as elasticity collision piece, and its elastic force not easily disappears, long service life.
The utility model is set to further: elastic hard Sealing includes the mounting groove be opened on gate panel body, one end extends in mounting groove, the other end is revealed in the sealing block outside mounting groove, the opening of mounting groove is provided with restriction boss, one end place that sealing block extends in mounting groove is installed with pressing plate, is provided with Compress Spring between this pressing plate and inwall of mounting groove.
Adopt technique scheme, it is simple that structure is set like this, easy accessibility, and Compress Spring is implemented to conflict to sealing block, when after sealing block wearing and tearing, also can keep with the sealing of valve seat, ensure that sealability.
The utility model is further set to: the joint of gate panel body and two lower rams offers attachment hole, and two lower rams are provided with the contiguous block extending to this attachment hole, and attachment hole is cone shape hole, is small end bottom it, and opening is large end.
Adopt technique scheme, the opening and closing being convenient to two lower rams are set like this.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the I portion enlarged diagram of Fig. 1.
Embodiment
The split type flashboard of wedge shape of a kind of gate valve as Figure 1-Figure 2, include top seal part 1 and the lower sealing portion 2 hinged with top seal part 1, top seal part 1 includes gate panel body 11, sealing place of gate panel body 11 is provided with elastic hard Sealing 12, lower sealing portion 2 includes two pieces can the lower rams 21 of opening and closing, the other end place that two lower part flashboards 21 splice one end is relatively respectively equipped with Sealing 22, the seal 22 is metal sealing block, metal sealing block can be irony or copper, all feasible, hinged by hinging shaft 3 between two lower rams 21 and gate panel body 11, two lower rams 21 offer installation cavity 23 relative to the other end place being connected one end with gate panel body 11, expansion sleeve 24 is provided with in installation cavity 23, at least lack one in expansion sleeve 24 and cavity volume 241 is installed, be provided with in the installation cavity volume 241 of expansion sleeve 24 and the elasticity collision piece 25 of installing cavity volume 241 sidewall and conflicting, this elasticity collision piece 25 is for being arranged in the elastic collar with opening installed in cavity volume 241.In such scheme, flashboard is set to top seal part 1 and lower sealing portion 2, makes the top and the bottom of the flashboard Packed function of tool respectively, make the valve seat place of valve body have double seal, ensure that the sealing of valve body; If the setting of elastic hard Sealing 12 makes gate panel body 11 conflict with the valve seat of valve body to implement to occur that wearing and tearing there will not be leakage when sealing, ensure that the sealing sealed herein on gate panel body 11; The setting of the expansion sleeve 24 between two lower rams 21 in installation cavity 23 can be implemented to control to the opening and closing of two lower rams 21, what drive expansion sleeve 24 to expand is then that it installs the elastic collar arranged in cavity volume 241, elastic collar is adopted to be because elastic collar is cheap as elasticity collision piece 25, and its elastic force not easily disappears, long service life.
