Abstract

The utility model discloses a floating flap valve device of a water drainage opening, which relates to the matching technical field in the water treatment technology. The utility modelaims to solve the technical problem of the control of the flap valve of the water drainage opening; the flap valve of the floating flap valve device is arranged at the pipe opening of a water drainage pipe with the pipe opening tangent plane in a tilted state, the rotating shaft of the flap valve is taken as a center, a left floating ball rod and a right floating ball rod are arranged at the other side corresponding to the flap valve, the rotating shaft of the flap valve is taken as the center, the flap valve is positioned at the front lower part of the water drainage pipe opening, and two left and right floating ball rods are positioned at the rear upper part of the water drainage pipe opening; a floating ball is respectively installed on the left floating ball rod and the right floating ball rod, the floating ball is fixed through an adjusting screw cap, the adjusting screw cap on the floating ball rods can adjust the position of the floating ball on the rods, and the distance (namely, the length of a lever) from the center of the floating ball to a rotating central shaft can be also adjusted through the adjustment, to achieve the purpose of presetting the closing time of the flap valve and the water surface position in a pool. The utility model has the characteristics that the relation of the closing time and the water level in the pool can be adjusted, the opening resistance is small, and the closure is tight.

Description

The unsteady flap valve device of water port

Technical field

The utility model relates to the supporting technology in the water technology, particularly relates to the control techniques of the unsteady flap valve of water port in a kind of water treatment system.

Background technology

In actual Engineering Projects, have a plurality of water port sometimes in the pond, draining simultaneously enters the pond, with water pump the water in the pond is taken away again.

As shown in Figure 1, first, second two water port B, C are arranged in the pond 7, processing requirement is that water pump A must preferentially take the water that the second water port C comes out away, and the water that the second water port C discharges definitely can not flow among the first water shoot B.Like this, during the discharge of the flow of water pump A when water pump A starts＞second water port C, water level will be reduced to low-water level 6, and the water that this moment will the first water shoot B flows into the pond to be mixed with the current of the second water port C, to reach the flow of heeling pump A.When water pump A stops, the second water port C is still in lasting draining, this moment, the pond median water level rose, meet and exceed the water outlet position of the first water shoot B, along with the pressure of water to the first water shoot B flap valve increases, the flap valve of the first water shoot B pipe will be closed, the water outlet tangent plane of first water shoot tilts, the upper edge is longer than in the lower edge, and when flap valve was closed, the angle of flap valve and level was less than 80 °.But the flap valve of design has following two shortcomings so in actual use:

A resistance is arranged when 1) opening, and this resistance derives from the deadweight of flap valve;

2) when water level difference was less, water was not enough to the pressure of flap valve, so the poor sealing of flap valve, had portion water can blow back among the first water shoot B.

The utility model content

At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides a kind of relation that can regulate turn-off time and pond median water level, and it is little to open resistance, the unsteady flap valve device of the water port that closure is tight.

In order to solve the problems of the technologies described above, the unsteady flap valve device of a kind of water port provided by the utility model, it is characterized in that, flap valve is located at the inclined water shoot mouth of pipe of mouth of pipe tangent plane, turning axle with flap valve is the center, two ball levers about the other side corresponding with flap valve established, and promptly the turning axle with flap valve is the center, flap valve is positioned at the front lower place of the draining mouth of pipe, and two ball levers are positioned at the back upper place of the draining mouth of pipe; About respectively adorn a ball float on two ball levers, with the adjusting fixed by nut that can regulate ball float position on ball lever, regulate by this and also just can adjust the distance (be lever length) of ball float center, to reach the purpose of presetting water surface site in time that flap valve closes and the pond to rotary middle spindle.

Further, the distance between the ball float of the described left and right sides is greater than the diameter of described water shoot.

Utilize the unsteady flap valve device of the water port that the utility model provides, one side owing to adopt the structure of establishing ball lever, ball float corresponding with flap valve, so its effect is:

1) gravity of ball float add ball lever gravitational equilibrium the weight of flap valve, resistance was littler when flap valve was opened, water outlet is more unobstructed;

2) the adjustable beat door time of closing and the relation of pond median water level, suffered pressure when also adjustable beat door is closed;

Because the suffered buoyancy function of ball float, flap valve was tightlyer closed when 3) flap valve was closed, and can guarantee therefore that water can not flow backwards to enter among the water shoot B.

Description of drawings

Fig. 1 is the structural representation that is provided with the pond of two water port;

Fig. 2 is the structural representation of unsteady flap valve device of the water port of the utility model embodiment;

Fig. 3 is that the Q of the utility model Fig. 2 embodiment is to view.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.

As Fig. 2, shown in Figure 3, the unsteady flap valve device of a kind of water port that the utility model embodiment is provided, it is characterized in that, flap valve 5 is located at the inclined water shoot B mouth of pipe of mouth of pipe tangent plane, turning axle 4 with flap valve is the center, two ball levers 3 about the other side corresponding with flap valve 5 established, promptly the turning axle 4 with flap valve is the center, flap valve 5 is positioned at the front lower place of water shoot B mouth, two ball levers 3 are positioned at the back upper place of the draining mouth of pipe, about respectively adorn a ball float 1 on two ball levers 3, nut 2 is fixing with regulating, be that adjusting nut on the ball lever can be regulated the position of ball float on bar, regulate by this and also just can adjust the distance (be lever length) of ball float center, to reach the purpose of presetting water surface site in time that flap valve closes and the pond to rotary middle spindle.Distance between two ball floats 1 is greater than the diameter of described water shoot B, the P so that ball float 1 can fluctuate on water shoot B two limits.

When pond during in low-water level, the water among the water shoot B can be washed flap valve open and flow out.Along with water level raises, ball float is immersed in the water gradually, and buoyancy of water begins the bolt down procedure of flap valve in advance.When water level continues to rise, owing to pressure and the ball float suffered buoyancy function of water to flap valve, flap valve can be closed effectively closely in the default moment.

Claims

1. the unsteady flap valve device of a water port is characterized in that, flap valve is located at the inclined water shoot mouth of pipe of mouth of pipe tangent plane, is the center with the turning axle of flap valve, two ball levers about the other side corresponding with flap valve established; About respectively adorn ball float on two ball levers, with the adjusting fixed by nut that can regulate ball float position on ball lever.

2. the unsteady flap valve device of water port according to claim 1 is characterized in that, the distance between the ball float of the described left and right sides is greater than the diameter of described water shoot.
