Abstract
The utility model relates to a reflux auto-controlled valve for a high-efficiency and reliable auto-suction pump. The utility model is characterized in that the whole reflux auto-controlled valve device is arranged at the outside of a pump body. The utility model has the advantages of convenient installation and adjustment, and sensitive and reliable closing and opening of the valve. Besides, the work efficiency of the inner mixed type auto-suction pump can be improved.
Description
The utility model belongs to the mechanical facilities of irrigation and drainage.
Existing irrigation and drainage self-priming pump divides two kinds of internal-mixing and external mixture types.The internal-mixing self-priming pump is better than external mixture type self-priming pump performance, and advantage is many; The internal-mixing self-priming pump, the lift flow loss is few under backflow valve opening buttoned-up status, efficient is high, self-priming performance good.But because the reflux design is unreasonable: the ball (playing the valve effect) that is in free state as 1. refluxing the valve opening design in the pump housing, relying on is close valve orifice directly.When ball and valve opening are in action radius, ball under the effect of press water, close valve orifice; When the distance of ball and valve opening was excessive, ball was subjected to the downward pressure of water can not close valve orifice; Like this, self-priming pump is in reflux state always, causes flow, lift to descend, and air horsepower raises, decrease in efficiency.When ball and valve opening distance was too small, when pump was not finished self-priming, ball was a close valve orifice, caused pump not to be in water state.2. ball forms fash in manufacture process, and the endless belt that still has a width, height not to wait after repairing when close valve orifice, still has part water refluxing like this.3. since valve opening and ball all in the pump housing, so can't adjust, therefore influence pass valve effect causes self-priming pump not reach design standard.
The purpose of this utility model is a kind of high efficient and reliable self-priming pump backflow internally piloted valve of design, solves the existing existing defective of internal-mixing self-priming pump reflux valve.
Its solution is that the whole series internally piloted valve device that refluxes is installed in pump housing outside, and valve is a taper, has guider, and unidirectional pressurized and supported by the valve holder can be by the height of valve holder regulating valve.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1: the schematic representation that self-priming pump combines with the automatic control reflux valve.
Fig. 2: sectional view of the present utility model.
Fig. 3: the sectional drawing of guider and valve body.
This backflow internally piloted valve by valve body (4), nozzle (5), guider (7), valve (8), valve holder (9), the bolt that discharges water (10), valve gap (12), and backflow valve opening (14) formed.
Connect with the pump housing (1) with reference to Fig. 1, Fig. 2, valve body (4), nozzle (5), backflow valve opening (14) communicate with pressure chamber (13) and suction chamber (6).When self-priming pump starts, give the water that adds in the pump housing and enter valve body (4) through backflow valve opening (14), valve (8) will be divided into suction chamber (6) (top) and pressure chamber (13) (below) in the valve.At this moment, valve (8) relies on deadweight to fall, and is in opening state, water in valve body (4), nozzle (5) sprays into the water intake of impeller 3, leaf opinion (3) rotation, water enters air-water separation chamber (2) after entering air mixing in the pump housing (1) and the pump housing (1), and gas is discharged through outlet valve (15), and water flow to the bottom of the pump housing (1), entering backflow valve opening (14) again circulates once more, air in the pump housing is got rid of clean, is full of water in the pump, finishes the self-priming process.Valve (8) is upwards closed rapidly under the effect of press water, has cut off the backflow of water, and self-priming pump enters normal operation.With reference to Fig. 2,3, guider (7) constitutes the top that cross is contained in valve (8) by two blades, valve (8) is an iron core rubber estate cone, valve holder (9) and valve gap (12) are equipped with in its below, valve holder (9) plays regulating valve (8), and the bolt that discharges water (10) is used for emitting the ponding in the pump housing.
The utility model compared with the prior art, its advantage is: it is unidirectional that valve (8) is subjected to the pressure of water, so close rapidly, sensitive reliable; Valve (8) is iron core rubber plantation cone, and with guider, closes tight; Because the whole device of this internally piloted valve is all outside the pump housing, so Be convenient to install and adjust, obviously improved self-priming pump performance and efficient.
Claims (3)
1, a kind of high efficient and reliable self-priming pump backflow internally piloted valve, it is made up of valve body (4), nozzle (5), guider (7), valve (8), valve holder (9), the bolt that discharges water (10), valve gap (12) and backflow valve opening (14), of the present utility modelly be characterised in that a whole set of high efficient and reliable self-priming pump backflow internally piloted valve is installed in the pump housing (1) outside, valve body (4) connects with the pump housing (1), and communicate by nozzle (5) and backflow valve opening (14), valve (8) is the unidirectional pressurized of taper, guider (7) is housed above it, valve holder (9) and valve gap (12) are housed below.
2, according to the described high efficient and reliable self-priming pump of claim (1) backflow internally piloted valve, it is characterized in that guider (7) constitutes cross by two blades.
3, according to the described high efficient and reliable self-priming pump of claim (1) backflow internally piloted valve, it is characterized in that being equipped with on the valve body (4) bolt that discharges water (10).
