Abstract
A pump tube omnipotent hydrant is a gate device for the pump tube of high lift water pumping station, which mainly solves the problems of water hammer eliminating, inverse stop, decompression, elbow replacing, stored water discharging, and vibration damping in high pressure water conveying pipelines. The six problems are solved in one body. The omnipotent hydrant is a casting hollow cylindrical iron shell which is equal to the water conveying tube in diameter and showed in a T-shaped and communicated with three holes. In the two holes communicated directly, the upper hole is a decompression hole, the lower hole is communicated with a water pump, and the side hole is communicated with the tube. The structure technique is characterized in that: when reverse water flow closes the lower hole, the upper hole automatically discharges the water in synchronous; when supplying water opens the lower hole, the upper hole is automatically closed in synchronous. The utility model can be applied as an omnipotent automatic protection hydrant in high pressure water conveying pipeline projects such as sprinkler irrigation, tube irrigation, leading water to hill, and so on.
Description
The utility model relates to a kind of being installed on the high-pressure water pipeline, the particularly water conservancy industry protective gear as decompression on the high pressure aqueducts such as sprinkling irrigation engineering, pipeline irrigation, city tap-water engineering, check, saving elbow, water hammer elimination, water discharging, vibration damping.
High-pressure water pipeline is by high-lift (high pressure) water pump, aqueduct, be formed by connecting, such high-pressure water pipeline such problem that is in operation: when sudden power termination of pumping (title pumping accident), current can unexpected reverse flow and impact water pump vane and make its impeller counter-rotating and burn pump motor in high-pressure water pipeline.
For addressing this problem, the common practice is to stop reverse current not impact water pump vane.Existing (see hydraulic and electric engineering for details and publish in June, 1984 front page " water pump and pumping station ") high-pressure water pipeline proposes in installing: gate valve, check valve are installed in the water pump front.For preventing owing to what reverse flow action produced pipeline to be produced the high pressure water hammer of explosion destruction in gate valve, check valve root moment, also need at check valve front installation water-hammer arrester and pipeline antivibration anchor block, consider that simultaneously north cold area is after engineering uses, for preventing the frost heaving failure pipeline, also need in aqueduct, build draining well to bleed off the unnecessary water yield in the pipeline by lowest part.But concerning the high-pressure water pipeline installation system, above-mentioned gate valve, check valve, elbow, water-hammer arrester, draining well, six kinds of equipment of anchor block are installed, expense height not only, and need certain manpower cost regular hour to go operation to finish, the high-pressure water pipeline system is built, installs, moves and cause certain difficulty.
The purpose of this utility model is the device that will provide a kind of improved collection gate valve function, elbow function, check valve function, water hammer to eliminate function, anchor block function, six one of pipeline water discharge function, it can automatically, effectively protect high-pressure water pipeline be not damaged because of pumping accident and high-pressure water pipeline not by explosion.
The purpose of this utility model is to realize like this, in high-pressure water pipeline the high-lift pump front install one cast in sky be the T-shape three aperture apparatus iron-clads that communicate according to water delivery caliber respective diameters, going up the hole in the two straight-through holes is pressure-reduction outlet, following hole and water pump are connected, and the 3rd hole and pipeline are connected.When reverse current of pumping accident during from the pipeline flow-direction water pump, the following aperture that connects the device of water pump is closed automatically, and open synchronously automatically in last hole, and water releases from last hole in the pipeline, thereby reach the purpose of high-pressure water pipeline decompression, check, water hammer elimination, water discharging, the assurance pipeline is not damaged.
The utility model is because only need install a kind of device on high-pressure water pipeline, rather than above-mentioned six kinds of devices.This device work is simultaneously finished automatically, rather than goes operation by the manpower spended time, and the structure starting point is to open synchronously when closing the following aperture of the device that connects one on water pump to go up the aperture, and reverse current release from last aperture.The starting point does not lie in the reverse current of blocking, thus simple in structure, reach the purpose of this utility model easily.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional drawing according to the high-pressure water pipeline multifunctional protection device that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
Task of the present utility model is finished like this: empty respective diameters continuous is "T"-shaped three holes (10) in casting according to different pipe diameters, (11), (12) apparatus main body iron-clad (9), casting one fixed support (5) in iron-clad, go up installation axle sleeve (4) at support (5), in axle sleeve, wear a cone sliding axle (2), end rigidity at cone sliding axle (2) connects a circular cover (8), its size is more bigger than water intake (10), after circular cover (8), establish sealing rubber cushion (7), guarantee when circular cover (8) is closed (12) under the water supply state airtight water-tight.Other tube having holes (11) is "T"-shaped, and (1) for returning water cover, (6) are maintenance gong bolt, and (13) are adpting flange.
When connecting a following hole of water pump (10) and flow to the other hole of one of connecting tube (11), circular cover (8) is opened under the effect of positive water pressure when the water forward flow, and promptly circular cover (8) is in position (15), will discharge water to go up aperture (13) sealing.Flow reversal is flowed when an other hole of connecting tube (11) flows to a connection following hole of water pump (10) in the pipe when pumping accident, circular cover this moment (8) slides to position (16) already by action of gravity and closes down hole (10), prevents reverse flow water slug water pump vane.Promptly slide on the position (16) by position (15).Open pressure-reduction outlet (13) and make flow through aperture (12) on the flow direction of aperture (11) and returning the disturbing according to arranging to the water source down of water cover (1) of reverse water, thereby subdued ducted malleation, eliminated ducted water hammer, protected water pump, pipeline.Simultaneously also drained ducted surplus water, avoided not draining the water in the pipeline and suffering frost heaving failure at northern area.Reached the purpose of automatic decompression, check, water hammer elimination, water discharging.So other hole meets at right angles alternative elbow with following hole during again owing to the water supply state.
The utility model is simple in structure, and cost is 1/10th of aforementioned six kinds of equipment total costs, is installed in only to be equivalent to install equally facility of a gate valve in the high-pressure water pipeline.Produce that this device only possesses casting condition, lathe equipments gets final product, and raw material is extensive.
