The automatic pressure release valve 1 and the hydraulic control valve 8 are both of a normally closed quick opening type.
The exhaust check valve 3 exhausts but does not discharge water in the water filling stage, and does not suck air in the siphon generation stage.
When the highest liquid level of the low-region water tank 5 is higher than the top of the siphon 2, the water injection equipment of the system is eliminated.
When the siphon system has no water quantity regulation requirement and the water quality does not influence the operation of the system, the low-region water source facility is cancelled, and the siphon 2 directly receives the incoming water.
By arranging the separate collecting and transmitting system, the water source in the high area can realize the water quantity and the water pressure requirement without additional power.
The system also comprises a branch pipe positioned on the siphon pipe 2, a check valve 14 is arranged on the branch pipe, a water ejector 15 is also arranged at the joint of the branch pipe and the siphon pipe 2, and the height of a water source in a high area meets the working pressure requirement of the water ejector 15.
The hydraulic pressure boosting mechanism adopts a lever and simplified piston structure, the piston 28 is pushed by the floating ball 21 and the lever 22 to realize obvious hydraulic pressure change, and enough displacement is completed, so that the hydraulic control valve 8 (also called a hydraulic control valve, which is of a normally closed quick opening type) is controlled to be opened.
Referring to the sectional view of the hydraulic booster mechanism 91 in fig. 5, the float 21 and the lever 22 are integrally fixed to the bracket 25 and the base plate 30 by the bolt shaft 24, one end of the piston rod 23 is fixed to the lever 22 by the bolt shaft 24, the other end is fixed to the piston 28 by the bolt shaft 24, and the piston 28 is disposed in the first piston cylinder 26.

An open flat plate is welded to the outer wall of the first piston cylinder 26 (i.e., the side close to the bottom plate 30 in the axial direction of the first piston cylinder 26), so that the first piston cylinder can also be fixed to the bracket 25 and the bottom plate 30 by bolts 29.
As shown in the sectional view of the hydraulic pressure relief mechanism 92 in FIG. 6, the hydraulic pressure relief mechanism 92 is a diaphragm structure, the flanged valve body 31 and the diaphragm 32 are fixed on the bottom plate 30 with a round hole by bolts, a closed pressure chamber is formed between the diaphragm 32 and the valve body 31, and the other side is directly communicated with the atmosphere because the whole bottom plate 30 is overhead by the expansion bolts 33 with foot pads. The pressure chamber is provided with a pressure source interface 36 which is directly connected with the top area of the siphon pipe 2 through a pneumatic pipe 13, a pneumatic rod cylinder 37 and a pneumatic rod 38 are arranged at the center of the outer side of the valve body 31, wherein the pneumatic rod 38 penetrates through the valve body 31, and a hydraulic pipe bracket 39 is used for fixing the hydraulic pipe 10 and the time-delay self-closing valve 34. When the pressure of the pressure chamber is reduced, the atmospheric air pushes the diaphragm 32 and the air pressure rod 38 to generate displacement, and the displacement of the air pressure rod 38 is used for opening the push-button type time-delay self-closing valve 34 on the hydraulic pipe 10, so that part of the high-pressure liquid medium in the hydraulic pipe 10 flows to the hydraulic medium tank 35, thereby rapidly reducing the pressure of the whole hydraulic pipe 10 and closing the hydraulic control valve 8. A hydraulic medium tank 35 with a cover plate and a vent hole is also bolted to the bottom plate 30.
When the liquid level of the low-region water pool 5 is gradually reduced, the floating ball 21 and the piston 28 are lowered due to gravity, the pressure of the hydraulic pipe 10 is reduced, the atmospheric pressure causes part of the liquid medium in the hydraulic medium box 35 to gradually flow back into the hydraulic pipe 10, and the time-delay self-closing valve 34 is still in an open state. When the liquid level of the low-region water pool 5 is lowered to the lowest point, siphoning is broken, the pressure cavity pressure of the hydraulic pressure relief mechanism 92 is increased, the time-delay self-closing valve 34 is automatically closed, the diaphragm 32 and the air pressure rod 38 are reset due to the combined action of the spring in the time-delay self-closing valve 34 and the atmospheric pressure, and the unpowered automatic siphoning system enters the next cycle.
The shaded portion of the base plate 30 is an open area to allow non-pressure cavity surface communication of the diaphragm 32 to atmosphere.
Example one
Referring to fig. 1, this embodiment belongs to a typical siphon system, and is applied to a situation where the highest water level of the low-region water tank 5 is lower than the top of the siphon 2, and of course, it is also a necessary condition that the difference between the lowest water level of the low-region water tank 5 and the top of the siphon is less than the maximum water pressure difference that the atmospheric pressure can bear, and the working process of the system is as follows:
the water supply is divided into areas, the high-area water source is collected and transmitted through an independent pipe network, no extra power is needed in the water injection process, the water level of the low-area water pool 5 rises gradually along with the continuous water injection of the water inlet pipe 4 of the low-area water pool 5 to the low-area water pool 5, when the water level reaches a threshold value, the siphon pilot valve 9 drives the hydraulic control valve 8 to be opened according to a liquid level signal, the high-area water source 7 starts to inject water into the siphon 2 through the water injection pipe 11, and meanwhile, the air in the siphon 2 is gradually exhausted through the exhaust one-way valve 3 which only exhausts the air but does not; after water injection is completed, the normally closed quick-opening automatic pressure relief valve 1 at the water outlet of the siphon pipe 2 is automatically opened when the pressure reaches a threshold value, meanwhile, after the siphon pilot valve 9 senses that the pressure of the siphon pipe 2 is suddenly reduced through the air pressure pipe 13, the hydraulic control valve 8 is driven to be closed, the exhaust one-way valve 3 is naturally closed when the pressure of the siphon pipe 2 is suddenly reduced, and therefore the whole siphon pipe 2 forms a complete closed system again, and the unpowered siphon process with high negative pressure is achieved. After siphon occurs, the liquid level of the low-region water pool 5 gradually drops, the floating ball 21 also gradually drops and resets under the action of gravity, when siphon is completed and damaged, the pressure at the top of the siphon pipe 2 suddenly rises, and therefore, the atmosphere cannot continuously provide thrust for the diaphragm of the hydraulic pressure relief mechanism 92, the time-delay self-closing valve 34 resets under the action of the spring, and the whole system enters the next cycle.
The embodiment is applied to municipal hydraulic engineering under special geological conditions, and can greatly save the construction cost. Different with current water pump vacuum diversion process is: the embodiment of the invention cancels a bottom valve or a check valve at the water inlet of the siphon 2 and adds the water seal elbow 12, thereby increasing the reliability of the system. However, this measure is based on the premise that the air remaining in the siphon tube 2 during the filling process is not sufficient to destroy the siphon phenomenon, otherwise a bottom valve or a check valve is required.
Therefore, the innovation of the embodiment is as follows:
(1) the water source system is vertically divided into regions (a high region water source and a low region water source) and the high region water source 7 provides energy required by water injection, so that the whole water injection and siphon process is automated by utilizing the gravitational potential energy of the high region water source, and the water injection process is realized by arranging an independent collecting and transmitting system under the condition of no external power because the water head is very low and the water quantity is very small, so that the method meets most of the practical engineering conditions;
(2) the siphon pilot valve 9 is adopted, so that the invention achieves the technical effect of unattended automatic siphon by a hydraulic control principle;
(3) the normally closed quick-opening automatic pressure relief valve 1 generally used in other scenes is introduced into the siphon system of the invention, so that the aim of automatically completing opening and closing according to the pressure change of the siphon 2 is fulfilled.
Example two
The application scenario of this embodiment is as follows: the highest water level of the low-region water pool 5 is usually higher than the top of the siphon pipe 2, and essentially, the highest water level of the low-region water pool 5 can meet the water level requirement for water injection of the siphon pipe 2, so that the high-region water source 7 and the water source of the low-region water pool 5 are combined into a whole, and therefore, some water injection related facilities in the first embodiment can be removed and not used in the present embodiment.
As shown in the attached figure 2, the automatic siphon process can be realized only by reserving the automatic pressure release valve 1, the siphon 2, the exhaust one-way valve 3, the low-region water pool inlet pipe 4, the low-region water pool 5 and the water absorption pool 6 with the filter screen. It should be noted that when there is no water regulation requirement and the water quality does not affect the system operation, even the low-region water tank inlet pipe 4, the low-region water tank 5 and the water suction well 6 with the filter screen can be cancelled, the siphon 2 directly receives the high-region water source 7, and the technical effect of automatic siphon can be realized through the cooperation of the automatic pressure relief valve 1 and the exhaust one-way valve 3. The embodiment can be widely applied to municipal administration, industry, water treatment and building water supply and drainage systems.
Therefore, the innovation of the embodiment is as follows: the automatic pressure relief valve 1 generally used in other scenes is introduced into the siphon system of the invention, and the automatic pressure relief valve 1 positioned at the water outlet of the siphon 2 realizes automatic siphon under the coordination of the exhaust one-way valve 3.
EXAMPLE III
As shown in fig. 3, the application scenario of the embodiment is as follows: the highest water level elevation of the low-region water pool 5 is lower than the elevation of the automatic pressure relief valve 1, and the height of the high-position water pool is enough. The system is characterized in that an automatic pressure relief valve 1 is connected with a siphon 2, a water ejector 15 is arranged on the siphon 2, a water suction port of the water ejector 15 is connected with a branch pipe of the siphon 2 to a water suction well 6 with a filter screen at the bottom of a low-region water pool 5, and a check valve 14 is also required to be arranged on the branch pipe.
Similar to the first and second embodiments, a plurality of exhaust check valves 3 are arranged on the main pipe of the siphon 2, and the water inlet end of the main pipe of the siphon 2 is connected with a high-area water source 7. Except that the high-area water source 7 should have a sufficient height that is vertically higher than the minimum working pressure value of the water ejector 15 than the water ejector 15. Through the arrangement, the technical effect of automatic siphon of the low-level water tank 5 can be achieved. It should be noted that: in practical application, in order to improve the safety and reliability, a standby submersible pump can be arranged in the low-level water tank 5 and is automatically started when the water level is ultrahigh.
In conclusion, the third embodiment is applied to high-rise buildings, the gravitational potential energy of the drainage of the high-rise buildings is fully utilized, the traditional gravity flow drainage is converted into pressure flow drainage, and meanwhile, the drainage of local depressions or basements can be discharged without power through the water ejector. The common usage scenario of the first and second embodiments is that the water source level is higher than the automatic pressure relief valve 1, and the usage scenario of the third embodiment shows that part of the water source level is lower than the automatic pressure relief valve 1.
