Abstract
The utility model discloses a large-scale one-way check valve, which comprises a valve body, a hanging rope and a supporting rotary shaft. One end of the hanging rope is tied at a position higher than the middle of the valve body while the other end is tied above the valve body, and the supporting rotary shaft is arranged on the top portion of the valve body. The large-scale one-way check valve can be opened and operated reliably when at a liquid difference of 150mm because the valve has large gyration radius and small opening force. The large-scale one-way check valve is closed by gravity by utilizing a dead load design and is reliable in sealing by utilizing foaming sponges to seal. The large-scale one-way check valve is free of constraint force or metal work, saves the valve body, is few in material usage and fine in economic indicators, is seawater corrosion resistant and has service life of 30-40 years.

The technological scheme that the prior art problems that solves the utility model adopts is: a kind of large-scale one way stop peturn valve is provided, and described one way stop peturn valve comprises: valve body, lifting rope and supporting revolving shaft; Described lifting rope one end lies in above position, valve body middle part, and the other end lies in the top of valve body; Supporting revolving shaft is located at the valve body top.
According to large-scale one way stop peturn valve one optimal technical scheme described in the utility model: described lifting rope lies in the immovable point of top of valve body and the distance on described valve body top is 1～3 meter.
According to large-scale one way stop peturn valve one optimal technical scheme described in the utility model: described large-scale one way stop peturn valve further comprises: the bipeltate sponge tube; Described bipeltate sponge tube is fixed on the outer of valve body by fixing device.
According to large-scale one way stop peturn valve one optimal technical scheme described in the utility model: described large-scale one way stop peturn valve further comprises: runner and counterweight; Described lifting rope one end passes runner and lies on the counterweight.
According to large-scale one way stop peturn valve one optimal technical scheme described in the utility model: described lifting rope coils on valve body forms
Type, and by
Go up node for two of type and draw the two ends of lifting rope, and lie in the top of valve body, described
Go up the above position, middle part that node is located at described valve body for two of type.
According to large-scale one way stop peturn valve one optimal technical scheme described in the utility model: described large-scale one way stop peturn valve adopts plastic material to make.
Beneficial technical effects of the present utility model is: large-scale one way stop peturn valve of the present utility model, because the bigger turning radius is arranged, opening force is little, and only the 150mm difference of liquid level is promptly opened, reliable operation.The design of employing dead-weight, gravity is closed; Utilize the foam sponge sealing, sealing is reliable.Do not have any restraining force, omitted valve body, few with material, economic indicator is good.No metalwork, seawater corrosion resistance, life-span 30-40.

Fig. 3 is that the bipeltate sponge tube among the large-scale one way stop peturn valve embodiment of the utility model combines schematic representation with valve body.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is elaborated.
Referring to Fig. 1～Fig. 3, Fig. 1 is the opened/closed schematic representation among the large-scale one way stop peturn valve embodiment of the utility model; Fig. 2 is the plan view among the large-scale one way stop peturn valve embodiment of the utility model; Fig. 3 is that the bipeltate sponge tube among the large-scale one way stop peturn valve embodiment of the utility model combines schematic representation with valve body.
In the present embodiment, described large-scale one way stop peturn valve is applicable to large-scale drainage pipeline networks and sea-water heat-pump engineering, and bore is greater than 1.5 rice diameters.
Described one way stop peturn valve comprises: valve body 1, lifting rope 2, supporting revolving shaft 3, bipeltate sponge tube 4, two runners 5 and two counterweights 6; Supporting revolving shaft 3 is located at valve body 1 top, is fixed on the borehole wall 7, and valve body 1 can be around supporting revolving shaft folding about in the of 3; Described bipeltate sponge tube 4 is fixed on the outer of valve body 1 by fixing device 9, keeps sealing with concrete duct 8; Described lifting rope 2 coils on valve body 1 forms
Type, and by
Go up the two ends (can make the pulling force of lifting rope 2 concentrate on a direction, make valve body 1 easier unlatching, closure) that node is drawn lifting rope 2 for two of type, described lifting rope 2 two ends are passed two runners 5 respectively and are lain in respectively on the counterweight 6; Runner 5 is fixed on the borehole wall 7, and runner 5 is two meters with the height of drawing node of lifting rope 2; Lifting rope 2 adopts nylon rope; Described large-scale one way stop peturn valve adopts plastic material to make, and the specification of described bipeltate sponge tube 4 is Φ 150.
Working principle: when at the incoming tide, sea level rise, and sea level fluctuations is greater than the water level in the concrete duct 8, and then seawater promotes the valve body closure; When ebb tide or concrete duct 8 when needing draining, the water level in the concrete duct 8 is greater than sea level fluctuations, and then valve body is open, and carries out draining, because two meters the turning radius is arranged, opening force is little, and only the 150mm difference of liquid level is promptly opened.
