Description
Technical field
The utility model relates to a kind of gate valve, is specifically related to a kind of blade type abrasion-proof slag-discharging valve.
Background technique
Gate valve is one of the most frequently used block valve, is mainly used to the medium connected or block in pipeline, does not apply to regulate rate-of flow.The pressure that usual gate valve uses, temperature and diameter range are very large, in especially applying to, large diameter pipeline.There is the problems such as Heavy Weight, volume are large in existing gate valve, during closedown, it is larger that flashboard falls required steering force, wastes time and energy, and also there is the hidden danger of closing time delay.
Summary of the invention
For the problem wasted time and energy when the flashboard solving existing gate valve in background technique cuts out, the utility model provides a kind of blade type abrasion-proof slag-discharging valve.
The technical solution of the utility model is: a kind of blade type abrasion-proof slag-discharging valve, comprise support, drive unit, valve gap, valve rod and valve body, flashboard is provided with in described valve body, described drive unit is connected with flashboard by valve rod, described valve body is provided with valve body sealing surface, and the side of described flashboard is the ram seal face suitable with valve body sealing surface, and the opposite side of described flashboard is shear plane, described ram seal face is plane, and described shear plane is inclined-plane.
Improve as one of the present utility model, described shear plane is inclined-plane wide at the top and narrow at the bottom.
As further improvement of the utility model, described valve body is provided with slag exhausting mouth in the below of flashboard.
As further improvement of the utility model, described slag exhausting mouth is camber.
As further improvement of the utility model, described valve body sealing surface and ram seal face are equipped with modifying material layer.
The beneficial effects of the utility model are, flashboard is provided with ram seal face and shear plane, cut and make ram seal face be that plane sealing is more reliable, shear plane is inclined-plane, when gate valve cuts out, shear plane can cut off the medium in valve body quickly and easily, more laborsaving more fast when making valve closing.The utility model also has that simple, compact to design, reasonable, the light-duty material-saving of structure, sealing are reliable, operation light and flexible, volume is little, passage is smooth, flow resistance is little, lightweight, easy installation, the advantage such as quick detachable, thoroughly solve the Heavy Weight of the valves such as common gate valve, plate valve, volume greatly, the not problem such as resistance to erosion, general cut-off valve can be replaced.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model embodiment.
In figure, 1, support; 2, drive unit; 3, valve gap; 4, valve rod; 5, valve body; 51, valve body sealing surface; 52, slag exhausting mouth; 6, flashboard; 61, ram seal face; 62, shear plane; 7, modifying material layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of blade type abrasion-proof slag-discharging valve, comprise support 1, drive unit 2, valve gap 3, valve rod 4 and valve body 5, be provided with flashboard 6 in described valve body 5, described drive unit 2 is connected with flashboard 6 by valve rod 4, and described valve body 5 is provided with valve body sealing surface 51, the side of described flashboard 6 is the ram seal face 61 suitable with valve body sealing surface 51, the opposite side of described flashboard 6 is shear plane 62, and described ram seal face 61 is plane, and described shear plane 62 is inclined-plane.The beneficial effects of the utility model are, flashboard is provided with ram seal face and shear plane, cut and make ram seal face be that plane sealing is more reliable, shear plane is inclined-plane, when gate valve cuts out, shear plane can cut off the medium in valve body quickly and easily, more laborsaving more fast when making valve closing.The utility model also has that simple, compact to design, reasonable, the light-duty material-saving of structure, sealing are reliable, operation light and flexible, volume is little, passage is smooth, flow resistance is little, lightweight, easy installation, the advantage such as quick detachable, thoroughly solve the Heavy Weight of the valves such as common gate valve, plate valve, volume greatly, the not problem such as resistance to erosion, general cut-off valve can be replaced.
Described shear plane 62 is inclined-plane (referring specifically to accompanying drawing 1) wide at the top and narrow at the bottom.The flashboard referring to close drive unit end wide at the top and narrow at the bottom is wide end, promoting or can playing leading role when falling, can better play the effect of shearing when bottom is the closedown of narrow end.
Described valve body 5 is provided with slag exhausting mouth 52 in the below of flashboard 6.Specifically, described slag exhausting mouth 52 is camber.Valve outlet end is designed with camber slag exhausting mouth, therefore this valve also has automatic blowdown function, specifically, be mainly reflected in the adhesion on scraped sealing surface, automatically clearing impurity, when flashboard falls, the dust piled up in slag exhausting mouth evokes by flashboard, and makes it along outside camber slag exhausting mouth exits valve body.
Described valve body sealing surface 51 and ram seal face 61 are equipped with modifying material layer 7, and modifying material layer can be the hard alloy layer such as sprayed wc, chromium carbide.Such structure, by the modifying surface process to sealing, makes sealing surface hardness can reach HRC more than 55, makes sealing surface form protective layer, has wear-resisting, that flushing resistance is higher effect, improve the working life of valve.
Every technician's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
