Abstract
The utility model discloses a novel gate valve. The gate valve comprises a valve body, wherein a gate plate is arranged in the valve body; a square groove is formed in the valve body and located below the gate plate; an arc-shaped part is arranged at the bottom of the gate plate; an openable-closable structure is formed at a coordination part of the arc-shaped part and the notch of the groove; when the gate plate is closed, the distance between the gate plate and the bottom of the groove is not larger than 0.5 cm. The openable-closable structure is formed at the coordination part of the arc-shaped part at the bottom of the gate plate and the notch of the groove, when the gate plate is closed, the bottom of the gate plate is near the bottom of the groove (that is, the distance between the bottom of gate plate and the bottom the groove is smaller), and the groove is shallow, so that impurities are not easy to gather at the bottom of the groove; when the gate plate is closed, the bottom of the groove can be cleaned through a water inlet valve and a water drainage valve; furthermore, a detergent can be used together to easily clean dirt at the bottom of the groove; even after long term use, the bottom of the groove can not accumulate a lot of dirt to generate a poor impermeability problem. In the valve body, the structure is compact; when the novel gate valve is mounted, the occupied space is small, and the gate valve is convenient to use.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of Novel Brake Valve.
Background technique
Gate valve refers to the valve that closure member (flashboard) moves along the Vertical direction of path center line.Gate valve is mainly used as to cut off in pipeline.Forged steel gate valve is to use very wide a kind of valve, and the shut-off means of general bore DN >=50mm is all selected it, and the shut-off means that bore is very little sometimes is also selected gate valve.Gate valve is as the lower valve of a kind of rank, more common.The open-shut device of gate valve is flashboard, and moving direction and the flow direction of flashboard are perpendicular, and gate valve can only be made standard-sized sheet and complete shut-down, can not make adjustments and throttling.The groove of flashboard for sluice valve of the prior art below often easily gathers impurity, is difficult to clean, and easily affects in the course of time the closure of flashboard, produces the not good problem of seal
Model utility content
The problems referred to above that exist in order to solve prior art, the utility model provides a kind of Novel Brake Valve.
To achieve these goals, the utility model adopts following technological scheme:
A kind of Novel Brake Valve, comprise valve body, in described valve body, be provided with flashboard, in described valve body and below being positioned at flashboard, be provided with square groove, it is characterized in that, described flashboard bottom has curved portions, and this curved portions coordinates formation opening-closing structure with described groove notch place, when after flashboard closure, described flashboard bottom is not more than 0.5cm with groove bottom land spacing.
Further: described bottom portion of groove is provided with inlet valve and water discharging valve.
Further: described groove notch place is provided with arc angling.
Further: described flashboard is hollow structure.
Further: described valve body top is provided with valve gap, described valve gap wears the column valve rod of vertical layout, and described valve rod top coordinates with the valve rod hole at valve rod place, and bottom is connected with flashboard, and described stem bottom and flashboard are integral type structure.
Compared to existing technology, the utlity model has following advantage:
1, the curved portions of the utility model flashboard bottom coordinates formation opening-closing structure with slot opening place, and after flashboard closure, flashboard bottom is near bottom portion of groove (flashboard bottom is less with bottom portion of groove spacing), and depth of groove is more shallow, and impurity is difficult for accumulating in bottom portion of groove.
2, after the utility model flashboard closure, can clean bottom portion of groove, then coordinate detergent by water inlet, water discharging valve, the dirt of bottom portion of groove bonding more easy to clean, also can not produce the not good problem of seal because bottom portion of groove gathers more dirt after long-term use.
3, each compact structure in the utility model valve body, the rear institute of installation takes up space less, uses more for convenience.
Brief description of the drawings

Fig. 2 is I place enlarged view in Fig. 1.
Fig. 3 is groove notch place enlarged view.
In figure, 1-valve body, 11-arc angling, 2-valve gap, 3-valve rod, 4-flashboard, 41-curved portions, 51-inlet valve, 52-water discharging valve,
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, 2, a kind of Novel Brake Valve, comprise valve body 1, in valve body 1, be provided with flow channels, in described valve body 1, be provided with flashboard 4, flashboard 4 is hollow structure, in described valve body 1 and be positioned at flashboard 4 belows and be provided with square groove, described flashboard 4 bottoms have curved portions 41, and this curved portions 41 coordinates formation opening-closing structure with described groove notch place, when after flashboard closure, described flashboard bottom is not more than 0.5cm with groove bottom land spacing.
Flashboard is hollow structure, and weight is lighter, and it is comparatively smooth and easy that flashboard opens and closes process, meanwhile, also material-saving of the flashboard of hollow structure, cost-saving; After flashboard closure, flashboard bottom is less with groove bottom land spacing, therefore the degree of depth of groove is more shallow, impurity is difficult for accumulating in bottom portion of groove, and the composition that is easily bonded as dirt with good adherence of bottom portion of groove simultaneously.
As shown in Figure 3, at groove notch, place is provided with arc angling 11, meanwhile, is provided with inlet valve and water discharging valve at bottom portion of groove.
Arc angling coordinates with the curved portions of flashboard bottom, jointly forms seal structure.
Valve body top is provided with valve gap 2, and described valve gap 2 wears the column valve rod 3 of vertical layout, and described valve rod 3 tops coordinate with the valve rod hole at valve gap place, and bottom is connected with flashboard, and described stem bottom and flashboard are integral type structure.
Because valve rod and flashboard are integral type structure, be convenient to maintenance, in dismounting and assembling process, save manpower.
The utility model working principle is as follows: by the rise and fall of valve rod, flashboard fit forms opening-closing structure, when after the long-term use of gate valve, the dirt of bottom adhesive is clean by the following method: first gate valve is in closed state, therefore form a confined space between gate valve and groove, coordinate water discharging valve to inject suitable detergent and the mixed solution of clean water by inlet valve, this detergent can be done corresponding selection according to the dirt composition of bottom portion of groove bonding, only otherwise can corrode the structures such as brake valve body, to be cleaned dose react a period of time with dirt after, pour clean water from inlet valve and (preferably there are the impact current of certain pressure, be convenient to wash away the dirt in groove), opening water discharge valve simultaneously, therefore detergent mixed solution and dirt are discharged the confined space between flashboard and groove.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
