Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a vertical self priming pump prevents siphon device, including the pump body 1, install motor 3 on the pump body 1, the both sides of the pump body 1 are equipped with inlet tube 5 and outlet pipe 2 respectively, the inside wall welding of the pump body 1 has fixed cover 6, be equipped with connecting pipe 4 between inlet tube 5 and the fixed cover 6, one side that connecting pipe 4 was kept away from to fixed cover 6 is equipped with regulation hole 8, the inside wall of fixed cover 6 is equipped with the spacing groove 10 that a plurality of levels set up, sliding connection has stopper 12 in the spacing groove 10, sliding connection has slide 9 in the fixed cover 6, slide 9 welds on stopper 12, one side bolt fastening that slide 9 is close to connecting pipe 4 has plunger 7, plunger 7 is the round platform shape structure.
In this embodiment, the welding has guide bar 11 in the spacing groove 10, and stopper 12 slides and cup joints on guide bar 11, and the outside cover of guide bar 11 is equipped with spring 13, and spring 13 is located stopper 12 and is close to one side of connecting pipe 4, and equal sealing connection between connecting pipe 4 and the inlet tube 5 and the pump body 1, plunger 7 are just facing the mouth of pipe of connecting pipe 4, and connecting pipe 4 is located more than two-thirds of the pump chamber height of the pump body 1.
Example (b): the plunger 7 is made of elastic materials such as rubber, when in use, the motor 3 drives the impeller in the pump body 1 to rotate, so that the pressure in the pump body 1 is greater than the pressure of the water inlet pipe 5, liquid enters the pump body 1 from the water inlet pipe 5 and is discharged through the water outlet pipe 2, when in use, the pressure used in the pump body 1 is greater than the pressure in the water inlet pipe 5, due to the existence of pressure difference, the sliding plate 9 moves towards the connecting pipe 4, the spring 13 is compressed, the plunger 7 plugs the pipe orifice of the connecting pipe 4 to place the liquid to flow back into the water inlet pipe 5, the plunger 7 is arranged into a circular truncated cone-shaped structure to be convenient for plugging the pipe orifice of the connecting pipe 4, the maximum diameter of the plunger 7 is greater than the inner diameter of the connecting pipe 4, the wear resistance is strong, the service life is prolonged, after the shutdown, due to the reduction of the pressure in the, when the liquid level in the pump body 1 descends to the position of the connecting pipe 4 because of siphon, gas enters the water inlet pipe 5 from the connecting pipe 4 to destroy the siphon, so that liquid is left in the pump body 1, and because the connecting pipe 4 is higher than two thirds of the height of the pump body 1, enough liquid is reserved in the pump body 1, and the next starting is facilitated.
