The present invention relates to a siphon device to be installed in a water or a water reservoir of a river or a reservoir, and more specifically, a large amount of siphon is induced and completed even in a water flush that has a gentle slope and a shallow depth of a downstream slope pipe. A large capacity siphon device capable of operating on a gentle slope.

The low drop large-capacity siphon device of Utility Model Registration No. 38920 (Notification No. 88-2486) of the applicant's prior application is shown in Fig. 6, about 1/2 of the drop H of the pipe diameter D of the siphon. In addition, the inclination of the siphon downstream inclination pipe 1, that is, the vertical height is A at the inclined surface and the inclination when the horizontal length from the point a to the same inclined surface is B is expressed as A: B.

Slope = A: B = 1: 1.1 In the range of shallow water, even the first-class water washing will trigger and complete the action of large-capacity siphon.

However, the downstream slope 20 of the tumbler to install the siphon is often in the range of 1: 1.1.

That is, as shown in FIG. 7, when the inclination of the downstream inclination pipe 1 is gentle and A: B is 1: 2, the reverse front surface 3 is used as the water of shallow water flowing naturally through the upper throat throat 2 Even if the flow is reversed by the downstream upper end portion 4 of the downstream inclined tube 1, the water vein does not reach the upper end portion 4, and the downstream inclined tube downstream of the siphon earthenware surface 5 or the reverse jaw 3 ( 1), the surrounding air downstream of the reverse jaw (3) is not only discharged first, but also flows as it is attached to the bottom of the sieve or reverse jaw (3) as it flows on the floor, so that the siphon tank (6) Since the water surface 5 is rippled and swollen, external air is sucked in intermittently in the direction of the arrow through the vicinity of the downstream upper end 4 of the downstream inclined tube 1 (see FIG. 7). Therefore, the siphon internal air was reduced to atmospheric pressure and the siphon action stopped. Therefore, when the reservoir level (8) rises to the rising level (8 '), it will fall naturally as it rises.

The present invention was devised to solve the above conventional drawbacks, and an object of the present invention is to act as a siphon even in a water flush leading to a shallow depth in a gentle slope within a range of 1: 2 inclination of a downstream inclined pipe. It is to provide a large-capacity siphon device that can operate on a gentle slope.

As a means for achieving the above object, the present invention is a siphon device in which the inclination of the siphon downstream inclination pipe is in the range of 1: 2, where a water vein flowing at a shallow depth is reversed and flowed from the reverse front to the downstream upper end of the downstream inclined pipe. The counter flow pipe and the pressure control pipe are installed so that the vacuum is generated in the downstream of the reverse front and absorbs the water outside the siphonto ball through the back of the reverse flow pipe, allowing the water to flow down the water and passing the reverse front. It is characterized in that it consists of a pressure control tube having a pressure control means for maintaining the upper and lower pressure of the water vein so as not to maintain the attachment vein.

According to the present invention, the inverted vein passing through the inverted jaw flows along the ceiling surface of the downstream inclined tube and enters the water surface of the earthenware tank, and the bubble mixture water generated at this time includes a large amount of air inside the guifern. Therefore, as the internal pressure of the siphon is eliminated much, as the low pressure develops, even the slight water washing naturally flowing from the reservoir to the shallow depth gradually increases the water intake to the siphon by the vacuum suction input, and the siphon action is completed, and the reservoir level is the secondary siphon inlet If it is lower than the water level, the siphon action is stopped because the low pressure inside the siphon is reduced to atmospheric pressure by sucking external air from the inlet of the auxiliary siphon.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2 show the side and the plane of the large-capacity siphon with a gentle slope in the range of 1: 2 in the inclination of the downstream inclined tube according to the present invention, and FIG. 3 shows a cross section of the throat 3, 4 is an enlarged view of the cross section of the backflow pipe. A pair of backflow pipes 10 are formed on both sides of the base portion downstream of the reverse jaw 3 attached to the inner bottom of the inclined pipe 1 shown. At this time, the suction port 11 downstream of the backflow pipe 10 is immersed in the water surface 5 of the siphon earthenware tank 6.

Each of the upper end 12 of the backflow pipe 10 is formed with a hole 12a communicating with each of the pressure regulating pipe 13 surrounding the outer circumference of the downstream inclined pipe 1, and the upper part of the pressure regulating pipe 13. A communication hole 14 communicating with the downstream inclined tube 1 is formed at the center bottom.

On the other hand, in order to make the direction of the reverse direction constant, a pair of communication holes 15 and 16 communicating with the side surface of the base part of the downstream inclination pipe 1 and the backflow pipe 10 are formed, respectively. At this time, the downstream communication hole 16 is immersed in the water surface 5 of the siphon earthenware tank 6, and the upstream communication hole 15 is formed to be close to the upper end 12 of the backflow pipe (10). desirable.

In the accompanying drawings, reference numeral 9 denotes a siphon intake port, 17 an auxiliary siphon, 18 an auxiliary siphon intake port, 19 is a communication hole between the auxiliary siphon and the headquarters siphon. .

The present invention configured as described above has a shallow depth as shown in FIG. 5 attached to the bottom of the downstream slope pipe 1 through the throat 2 through the throat 2 to the downstream slope pipe 1 at the reverse front 3. Reverse flow in the direction of the downstream upper end (4), and vacuum is generated immediately downstream of the reverse threshold (3). The reverse vein is maintained by the pressure control tube 13 and the communication hole 14 in the lower part of the center to equalize the air pressure of the water vein above and below the water vein so that the direction of flowing down does not occur.

On the other hand, in the falling water surface of the drainage vein, that is, the downstream upper end portion 4 of the downstream inclined pipe (1), since the bubble water is vigorously formed, the internal air of the siphon device is included in the bubble water. The inside of the chamber becomes low pressure, so that the amount of water suctioned from the siphon suction port 9 also increases.

In addition, since a vacuum is generated immediately downstream of the reverse jaw 3, water outside the siphon earthenware is absorbed through the suction port 11 of the backflow pipe 10 immersed in the water surface 5 of the siphon earthenware tank 6 so that the reverse threshold (3) It spreads downstream and joins the reversal vein. This prevents the reversal vein from becoming an adherent vein even if the force becomes stronger.

In this state, the water passing through the throat part 2 and the water flowed back from the backflow pipe 10 flow together in the downstream inclined pipe 1, where most of the water flows but some of the water is siphon inlet ( 9) and the inside of the siphon earthenware, i.e., on the upper and lower sides, rise higher than the inner bottom of the throat 2 in the order of (5a) (5b) (5c) (5d) (5e), and the siphon earth ball tank (6). The amount of flowing water from the outside of the water surface 7 of the () also increases in the order of (7a) (7b) (7c) (7d) (7e). However, the rise level 8 'of the reservoir is only a few (cm).

In this way, when the landing of the drainage vein rises higher than the downstream upper end portion 4 of the downstream inclination pipe 1, the downstream inclination pipe 1 is filled with water repellent water, and the water level in the suction port 9 becomes the rising level of the reservoir ( 8) As it rises, the backflow pipe (10) sucks the outside of the siphon earth ball, and since the air intake is suppressed, it continues to descend by the piston type, and the air inside the siphon is included in the bubble water and the low pressure is removed. The siphon action is completed by continuously inhaling a large amount of water in the reservoir from the siphon suction port 9 to the developed low pressure.

Subsequently, when the supply amount (flood amount) decreases, the rising water level 8 'of the resin is lower than the intake port 18 of the auxiliary siphon 17, so that external air is sucked in from the auxiliary siphon intake port 18. As a result, the low pressure inside the siphon is reduced to atmospheric pressure, and the siphon stops working.

As described above, the large-capacity siphon device with a gentle slope according to the present invention does not have electric or mechanical power, and the siphon acts even at a shallow depth of water within the range of a gentle slope where the slope of the downstream inclined tube is 1: 2. This is triggered and has the effect that the completion of work and stop automatically proceed without electric power or mechanical power.
