Abstract
The utility model relates to a top sucking vacuum water diversion apparatus, which is characterized in that the top of the cylindrical vacuum water diversion tank is provided with a top sucking water pipe which is in reverse L-shaped and can extend to the internal part of the low-order pond, and the lower part of the side wall of the vacuum water diversion tank is provided with a water pumping pipe which is connected with the water pump. The vacuum water diversion tank can adopt an elliptical sealing head, and the ratio of the pipe diameters of the top sucking water pipe and the water pumping pipe is preferably 1.2 to 1.5: 1. The utility model has the characteristics of simple structure, convenient manufacture and processing, flexible installation and usage, high water pumping efficiency, stable and reliable water diversion performance, long service life, etc.
Description
The utility model relates to the device that prevents vapour lock when a kind of raw water service pump starts, especially a kind of top sucking type vacuum water diversion device.
At present, how vacuum dehydration pump commonly used prevents the supplementary equipment of vapour lock with the conduct of lower suction type vacuum tank, because its suction mouth of pipe and connect the water pump outlet pipe mouth and must be arranged at tank body two side lower parts with 180 ° of means of fixation, thereby its installation setting can be subjected to the place when construction, spatial constraints influences using effect.Chinese patent CN2143265Y discloses a kind of " pump scuttlebutt ", its main structure feature is being separated by dividing plate jar and the lower tank bottom is provided with the effluent pipe mouth that is connected with pump and the mouth of pipe that draws water respectively, also is provided with a suction sleeve that stretches in the low pool bottom its lower tank.When starting water pump because in the upper tank body backflow prevention of water vapour lock, by producing negative pressure in the lower tank with making in the water suction upper tank body in the lower tank.Through suction sleeve the water in the low pool is sucked wherein.This pump is comparatively complicated with the scuttlebutt structure, makes trouble is installed also, and particularly pressure is born on its dividing plate top, and the bottom is under the condition of negative pressure, and material and processing are all had certain requirement.In addition, be in the elevated pressures state in its upper tank body all the time, the water pump pressure head is reduced, influence the efficient of water pump.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of simple in structure, and it is convenient to make, and flexible for installation, the efficient of drawing water height and diversion are stable and reliable for performance, the top sucking type vacuum water diversion device of long service life.
The purpose of this utility model can reach by implementing following technical proposal: be provided with at the top of cylindrical vacuum water diversion tank body and be down L shaped and extend to top suction sleeve in the low pool, be provided with the drinking-water pipe that is connected with water pump in the lower sidewall of vacuum water diversion tank body.In order to obtain better using effect, the upper design of above-mentioned vacuum water diversion tank body can be become ellipse head, top suction sleeve inlet is positioned at its central highest point, so that water inlet and exhaust, described top suction sleeve is 1.2～1.5: 1 with ratio the best of the caliber of drinking-water pipe, can improve the performance of drawing water of device like this, the volume of institute's retaining part its upper space and top suction sleeve spatial volume 3～4 times preferably in the vacuum water diversion tank body are so that guarantee the reliable and stable of starting mode of pump.
Accompanying drawing is the utility model embodiment's a structural representation.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.At the top of cylindrical vacuum water diversion tank body 1 ellipse head 2 is set, its middle position is connected to and is down L shaped and extends to top suction sleeve 3 in the low pool, the lower sidewall of vacuum water diversion tank body 1 is provided with the drinking-water pipe 5 that links to each other with water pump 4, and above-mentioned top suction sleeve 3 is 1.3: 1 with the ratio of the caliber of drinking-water pipe 5.Also be respectively equipped with the outlet pipe 6 that is used to get rid of air in the jar on the top of ellipse head 2, the irrigation pipe 7 of water filling when being used for using first and the vacuum gauge 8 of measuring degree of vacuum in the index pot.The volume that is filled with water in the described vacuum water diversion tank body 1 should be its top and ellipse head 2 interior spaces and top suction sleeve 3 interior spatial volume sums 3 times.When using the utility model device first, to open the valve on the outlet pipe 6 earlier, through being full of water in jar after, irrigation pipe 7 closes the valve on the above-mentioned pipeline.Open water pump 4 and draw water, produce negative pressure along with the decline of tank level, will replenish in the water suction tank in the low pool by top suction sleeve 3, liquid level stabilizing is constant when reaching the turnover water balance, and this moment is continuous water supply normally just.When after water pump 4 is shut down, restarting later on and since jar in sufficient water, thereby need not add any operation, can directly enter the water supply state.
The utility model has and makes simply compared with prior art, makes the processing facility, installs and uses spirit Live, the efficient of drawing water height and diversion are stable and reliable for performance, the characteristics such as long service life.
