Abstract
The utility model relates to a flange connection type round right-side opening pontoon flap valve, belongs to a pontoon flap valve, and mainly solves problems that an opening angle of a conventional valve is small, the head loss is large, the valve cannot be sealed completely, and the like. The technical scheme of the flap valve is as follows: a P-type water seal (2) is adopted, an adjusting plate (4) is arranged on the right side of a valve body (1) and connected and sealed with a rotary arm (7), and a pontoon door (3) is arranged on the rotary arm (7) and located below the P-shaped water seal (2), so that medium leakage is avoided; and according to a mechanics principle, hinge lugs (5) and a round head shaft pin (6) are vertically arranged and inclined inwards by 3 degrees, and the pontoon door (3) uses self-prossessed horizontal component force as power, so that large opening angle, small head loss, automatic closing and complete sealing can be achieved, and the flap valve is mainly used for cutting off flow of an irrigation and drainage pump station.
Description
Technical field
The utility model relates to a kind of drainage and irrigation equipment, and particularly buoyancy tank flap valve valve is driven on the round right side of a kind of flange coupling formula.
Background technique
Defectives such as at present, at home, in the outer pump on drainage irrigation station, the water valve of use generally is a kind of outstanding formula safety check that opens, and thisly outstandingly opens the formula safety check, exists the valve opening angle little, and loss of head is big and be difficult to seal fully.Up to the present, it is big also not see a kind of valve opening angle on market as yet, and loss of head is little, can either close automatically, and buoyancy tank flap valve valve is driven on the round right side of flange coupling formula that can seal fully again.
The Zhang Jian of existing No. 408, Building 22, Dormitory Of Hydraulic Component Factory, Shaoyang City, Hunan Province is in application on January 20th, 2009 disclosed 200920062986.X on November 4th, 2009 " buoyancy tank flap valve valve is driven on energy-saving built-in type right side ", comprise valve body, rubber ring, flap valve, rear flange and hinge, it is characterized in that: the front end at valve body is provided with rubber ring, be provided with flap valve in the rubber ring front, tail end at valve body is provided with rear flange, be provided with hinge on valve body front end the right, flap valve is installed on the hinge, hinge and the flap valve on valve body front end the right are vertically arranged, when installation is pre-buried, valve body is rotated to an angle left.This achievement is not determined the best angle of swing of valve body, and the sealability of rubber ring is not strong and working life is short; The utility model will cut with scissors ear and the cup head pivot pin is vertically arranged, and tilts inwards 3 °, and uses P type water seal 2, is provided with regulator plate 4 on valve body 1 right side, and regulator plate 4 can be regulated the sealing off gap between buoyancy tank door 3 and the valve body 1, avoids dielectric leakage, makes better effects if.
Summary of the invention
The purpose of this utility model provides a kind of round right side of flange coupling formula and drives buoyancy tank flap valve valve.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises that valve body 1, P type water seal 2, buoyancy tank door 3, regulator plate 4, hinge ear 5, cup head pivot pin 6 is characterized in that: two ends are provided with P type water seal 2 below valve body 1, be provided with regulator plate 4 on valve body 1 right side, regulator plate 4 is connected with spiral arm 7 by hinge ear 5, be provided with cup head pivot pin 6 in the hinge ear 5, buoyancy tank door 3 is positioned at P type water seal 2 belows and is arranged on the spiral arm.
Valve body 1 described in the utility model is cylindrical shape.
The beneficial effects of the utility model are: opening angle is big, and loss of head is little, can either close automatically, can seal fully again.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of facing of Fig. 1.
Fig. 3 is the A portion structure for amplifying schematic representation of Fig. 2.
Among the figure: the 1-valve body, the water seal of 2-P type, 3-buoyancy tank door, the 4-regulator plate, 5-cuts with scissors ear, 6-cup head pivot pin, 7-spiral arm.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
Embodiment 7, and hinge described in the utility model comprises hinge ear, bearing pin and pad, are provided with bearing pin in the hinge ear, and bearing pin one end is arranged to the semicircle capitiform, is provided with pad above the semicircle head end; Also can between hinge ear and bearing pin, be provided with lining.It according to mechanics principle, is arranged on force side with the semicircle head end by pivot pin one end is arranged to the semicircle capitiform, can play a supportive role, when being arranged to the situation of several angle, the power of can reducing friction makes the buoyancy tank door rely on the horizontal component of self gravitation to reach and closes and the purpose of opening.It mainly is to connect be used to the buoyancy tank door of driving buoyancy tank flap valve valve.Consult Fig. 1 to 3, all the other are with above-mentioned embodiment.
Claims (4)
