Abstract

The utility model relates to a vacuum siphon pipe water conveying device, which is formed by a water conveying pipe, a connecting flange, a bearing support, an air intake valve, a buffer tank, a vacuum pump, a suction pipe and a filter. After the vacuum siphon pipe water conveying device is installed on a dam, water on the side of high water level can be conveniently and reliably conveyed to the side of low water level. Moreover, the vacuum siphon pipe water conveying device has the advantages of convenient connection and disconnection control, no water leakage, reliably action, convenient maintenance, long service life and the like, can partially substitute for gates and valves and plays a great role in aspects such as flood control, tide barrage, flood drainage, irrigation, water supply, environmental protection, hydroelectric generation and the like.

Description

The vacuum siphon pipe is crossed the water device

Technical field

The utility model belongs to the water conservancy project mechanical field, is a kind of device that is used to connect and block current.

Background technique

Gate is extensively adopted in hydraulic engineering, China has seat surplus the sluice 50,000 at present, gate is applied to aspects such as flood control, retaining tide, water drainage, irrigation, water supply, environmental protection, shipping and hydroelectric power, 1., gate is fragile, as the old damage of gate, corrosion, sealer ageing inefficacy, hoist and service bridge damage, artificial destruction etc. but there is following defective in gate in hydraulic engineering:; 2., the construction cost height, a purposes need be built main gate, bulkhead gate and emergency gate, hoist, control station for the sake of assurance simultaneously; 3., hoisting capacity is big, consumption of power is many; 4., dangerous big, in case gate lost efficacy, can cause beyond measure property loss and casualties to the downstream.

Summary of the invention

1., can realize blocking and conducting current easily the purpose of this utility model is that a kind of vacuum siphon pipe is crossed the water device, and its can most of replace gate and small part replaces valve, and has the following advantages:; 2., durable in use, be difficult to damage, even break down, also be easy to repair; 3., construction cost is low, main parts size is pipeline only, vacuum pump, stop valve and canister (knock out drum); 4., hoisting capacity is little, energy-conservation; 5., not dangerous, can not cause downstream flood disaster even lose efficacy yet.

Solution of the present utility model is as follows: the utility model is by crossing water pipe, adpting flange, bearing support, suction valve, knock out drum, vacuum pump, exhaust tube and filter are formed, crossing water pipe is an inverted U bend, its feed-water end connects filter, intake pipe generally adopts steel pipe, also can adopt cast iron tube, cement pipe, plastic tube etc., cross water pipe and can be (the welding of a homogeneous tube, bonding multistage pipe is considered as homogeneous tube), also can be formed by connecting by two above short tubes, its Placement has flange to connect and is threaded, be connected in series knock out drum and vacuum pump at the lofty perch of crossing water pipe successively with exhaust tube, vacuum pump is connected in the top of knock out drum, vacuum pump, knock out drum and mistake water pipe interconnect by exhaust tube, suction valve is by exhaust tube and cross cross current, and suction valve has four kinds with the mode of communicating of crossing water pipe: 1., suction valve directly connected water pipe; 2., suction valve was connected on the exhaust tube between water pipe and the knock out drum.3., suction valve is connected on the knock out drum; 4., suction valve is connected on the exhaust tube between knock out drum and the vacuum pump.Vacuum pump adopts pumping speed fast, it is suitable that degree of vacuum is higher than 0.1 atmospheric type, can adopt vacuum displacement pump (piston type, Luo Cishi, blade type etc.), centrifugal vacuum pump (induced draft fan), Nash hytor, vapor stream diffusion pump, turbomolecular pump etc.

Operating principle of the present utility model is as follows: during installation, need all to be immersed in inside and outside the dykes and dams below the water surface with crossing the import of water pipe and outlet, when needing water flowing, start vacuum pump, when treating that the interior air of water pipe was taken away fully, the water on high-order limit will be closed vacuum pump this moment along crossing water pipe because the effect of atmospheric pressure flows to the low water level limit, and current continue to flow; In the time of need blocking current, only need open suction valve, the degree of vacuum of destroying water pipe gets final product.The effect of knock out drum is to be convenient to observe the SEA LEVEL VARIATION of water pipe and to prevent that sealing enters vacuum pump.The water height that exceeds most that this vacuum syphon tube is crossed the water device is 10 meters, because water can seethe with excitement under the low pressure, general height difference should be controlled at 4～8 meters, and summer is low, and winter is higher.

1., can make things convenient for and realize blocking and conducting like a cork the utility model has the advantages that: current; 2., can accomplish watertightly, this is that any gate and valve are not accomplished; 3., be difficult to be out of order, even be out of order, also neither threaten downstream safety, can conveniently fix again; 4., construction cost is low; 5., can call in the time of zero; 6., no hoisting capacity; Unless 7. breach a dyke, be safe from danger.
