Description
Technical field
The utility model belongs to plumbing equipment technical field, is specifically related to a kind of floating-tube type automatic control flap valve.
Background technique
Existing flap valve can not intelligent automatic control, flexibility is little, due to the poor sealing performance that door-plate own wt is overweight and close behind the door, produce strong shock between door-plate and door body when very large energy loss being caused to the current passed through and to close and close the leakage etc. of water body behind the door, and the opening force after existing flap valve installation, the planeness etc. of closing behind the door between door-plate and door body sealing surface are all difficult to ensure, therefore overcurrent damage by water is greatly the major defect of existing flap valve.
Model utility content
The purpose of this utility model is exactly the defect for prior art, provides a kind of floating-tube type automatic control flap valve.Be applicable to sewerage, outflow opening, flow-off, store rain pond etc.
The technical solution adopted in the utility model is: comprise the door body having runner, and the external wall of described door is fixed with cylindrical tube, and the longitudinal center cross section of described body is the trapezium structure of short bottom, top length, and described body exterior edge face forms the runner mouth of inclination; One end of the external side of described door and pole is hinged, the other end and the floating drum of described pole are fixed, one end of described pole and the hinged one end of door body and connecting rod is fixed, the other end and weighted lever frame one end of described connecting rod are hinged, one end of described weighted lever frame and rod hinge connection is fixed with balancing weight, described weighted lever frame stage casing is hinged in body top exterior walls, hinged outside the described weighted lever frame the other end and door-plate, when door-plate cuts out, seal with body exterior edge face inside described door-plate and contact.
Preferred structure further, described weighted lever frame is two vertical poles and two cross bars vertical frame structure connected and composed mutually, described balancing weight is arranged on cross bar, one end and the pole of described connecting rod are fixed, the other end of described connecting rod and the end of cross bar hinged, the stage casing of described vertical pole is hinged in body top exterior walls, hinged outside the end of described vertical pole and door-plate.
Preferred structure further, described body top exterior walls is provided with fixed plate, and described weighted lever frame stage casing is hinged on fixed plate.
Preferred structure further, described floating drum is cylindrical.
Preferred structure further, the external sidewall of described door is provided with stiffening rib.
The utility model floating-tube type automatic control flap valve is designed with stainless steel floating drum and weighted lever frame, the opening and closing of door-plate are controlled by the height of water level, control for prevention backwater and flood provide reliable floating-point, wherein, the balancing weight that weighted lever frame is arranged effectively ensure that the normal unlatching of door-plate, floating drum effectively ensure that the closedown of door-plate, avoids leakage, reduces damage by water.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form restriction to the utility model.
As shown in Fig. 1-Fig. 4, the utility model comprises the door body 1 having runner, and described door body 1 outer wall is fixed with cylindrical tube 2, and the longitudinal center cross section of described body 2 is the trapezium structure of short bottom, top length, and described body 2 exterior edge face forms the runner mouth of inclination, hinged with one end of pole 4 by rotating shaft 11 outside described door body 1, the other end and the cylindrical float 5 of described pole 4 are fixed, one end of one end that described pole 4 is hinged with door body 1 and connecting rod 6 is fixed, the other end and weighted lever frame 7 one end of described connecting rod 6 are hinged, one end that described weighted lever frame 7 is hinged with connecting rod 6 is fixed with balancing weight 8, described weighted lever frame 7 stage casing is hinged on fixed plate 9 that body 2 top exterior walls is arranged, hinged outside described weighted lever frame 7 the other end and door-plate 3, when door-plate 3 cuts out, seal with body 2 exterior edge face inside described door-plate 3 and contact, described door body 1 outer side wall is provided with stiffening rib 10.
In such scheme, as shown in Figure 2, Figure 4 shows, described weighted lever frame 7 is two vertical poles 7.1 and two cross bars 7.2 vertical frame structure connected and composed mutually, described balancing weight 8 is arranged on cross bar 7.2, one end and the pole 5 of described connecting rod 6 are fixed, the other end of described connecting rod 6 and the end of cross bar 7.2 hinged, the stage casing of described vertical pole 7.1 is hinged in body 2 top exterior walls, hinged outside the end of described vertical pole 7.1 and door-plate 3.
Working principle of the present utility model: the overall fixed hole 12 by door body edge of the utility model is installed on piping flange and wall, under normal state, by lever principle, under the effect of balancing weight and floating drum gravity, valve is in the state of standard-sized sheet, without flow resistance time water passes through; By the opening and closing of the elevating control door-plate of floating drum, when outlet end water level rises to certain altitude, floating drum is subject to buoyancy upwards, promotes door-plate and move downward under connecting rod effect, and then closes door-plate, prevents from flowing backwards.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
