Abstract
The utility model provides a bottom pumping type vacuum water diversion device which is characterized in that the upper part and the lower part of a cylindrical water diversion tank are respectively connected with an elliptical upper sealing head and an elliptical lower sealing head; a water suction pipe enters the tank from the side surface of the tank, and the water suction pipe can upwards extend to the elliptical upper sealing head in the tank. The bottom of the elliptical lower sealing head is connected with a water pumping pipe which is connected with a water pump. A communicating pipe with a water discharge valve is arranged between the water suction pipe and the water pumping pipe. The utility model has the characteristics of simple and reasonable structure, convenient manufacture and installation, good and stable water diversion performance, no stagnation zone and pollution in the tank, no stress concentration, long service life, etc.
Description
The utility model relates to the device that prevents the vapour lock generation when a kind of raw water service pump starts, especially a kind of bottom pumping type vacuum water diversion device.
Existing water pump adopts flat-top, flat vacuum tank with the vacuum water diversion device great majority, and its water sucking mouth and pump mouth all are opened in the bottom of tank body and become 180 ° of angle stationary distribution.This vacuum water diversion device is convenient inadequately when installing and locating, and there is certain distance its pump mouth and bottom plane, water has the stagnant area in jar, be difficult for draining, thereby apt to deteriorate and pollute, the more important thing is since jar in constantly be subjected to periodic malleation, the influence of negative pressure alternation, concentrated and easily produce fatigue crack to the stress of its bottom and top plan soldered, reduced its working life, and using effect is not good enough.
The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, proposes a kind of simple and reasonable for structurely, and it is convenient to make and install, the diversion performance is good and stable, reliable, current do not have the stagnant area in jar, and are unstressed concentrated, the bottom pumping type vacuum water diversion device of long service life.
The purpose of this utility model can reach by implementing following technical proposal: be connected with an oval-shaped upper and lower end socket respectively in the upper and lower of cylindrical vacuum water diversion tank body, suction sleeve enters wherein from the tank body side, and extend upwardly to oval upper cover place, be connected to the drinking-water pipe that is connected with water pump in the bottom of oval lower seal head.This drinking-water pipe preferably is located at the lowest part of described oval lower seal head, so that the water in the jar is drained; The connecting tube that preferably also is connected a band drain valve between above-mentioned suction sleeve and drinking-water pipe is so that discharging surplus water wherein during the maintenance tank body.
Accompanying drawing is the utility model embodiment's a structural representation.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.Be welded with oval upper cover 2 and oval lower seal head 3 respectively in the upper and lower of cylindrical vacuum water diversion tank body 1, suction sleeve 4 stage casings that are N shape are passed tank body 1 and are extended upwardly to oval upper cover 2 places therein.These upper cover 2 tops also are provided with vacuum gauge 5, water injecting pipe 6 and outlet pipe 7.Lowest part in lower seal head 3 bottoms is connected to the drinking-water pipe 9 that is connected with water pump 8 water inlets, also is connected to the connecting tube 10 of a band drain valve between described drinking-water pipe 9 and the suction sleeve 4.When using the utility model product first,, close outlet pipe 7 after waiting to fill and water injecting pipe 6 can come into operation as long as open outlet pipe 7 and water is entered in tank body 1 and the upper and lower end socket 2,3 via water injecting pipe 6 perfusions.When opening water pump 8 and supply water, along with water in the jar is taken away, liquid level descends and produces negative pressure, is replenished in the water suction tank in the low pool through suction sleeve 4, in jar, reach balance into and out of the water yield till.After this, water pump 8 during repeated priming, all need not any manual operation at any time, by the water in the tank body 1 replenish automatically, diversion, make it enter normal pump pressure water supply working state.When maintenance tank body 1, also only need drain valve is opened, surplus water just flows back in the low pool through suction sleeve 4 in jar.
The utility model has simple and reasonable for structurely compared with prior art, and it is convenient to make and install, and draws Water-based can be good and stable, reliable, no stagnant area in the tank, and pollution-free, so unstressed concentration phenomenon is service life Than characteristics such as length, can be widely used as the pump vacuum water diversion device of low water level.
