Definitions

  • Valve in particular for priming circuit of a pump.
  • the present invention relates to valves which can be used in particular, but not exclusively, da the priming circuit of a pump. It is known to provide, in pumps, a valve which, when open, allows inte circulation between the discharge and the suction. Water is sprayed from the suction inlet of the first wheel and carries with it part of the air from the suction chamber. depression is created in the suction and water rises in the pipes. The air-laden water arrives in the discharge chamber where decantation takes place. The decan water returns to the suction, passing through the valve, and the cycle begins again. The water gradually rises in the suction pipe as the air is removed. When the air is completely evacuated, the water completely fills the pump and the rise in pressure causes the valve to close. The pump is primed.
  • valve comprises return spring. It is a mechanical part which can make good master of the dimensions. But the return spring is in the passage of the liquid, which requires frequent cleaning.
  • an automatic priming system pump comprising, as a valve, a deformable rubber tube. This direct flow valve does not require cleaning. But the rubber tube ages over time, so that its mechanical characteristics become uncertain.
  • the invention overcomes the drawbacks of the front valves by a new valve which combines the advantages of the front valves.
  • This valve comprises a seat provided with an orifice and a shutter mounted so that it can be applied to the seat in front of the orifice.
  • the shutter is an elastic blade embedded on one side and whose flexibility increases from the embedded side to the end opposite this side.
  • the invention also relates to a pump with priming circuit comprising a valve, the seat of which is threaded in a slide formed on a priming element fixed on the pump body, the valve being in accordance with the invention.
  • FIG. 1 is a partial sectional view of a pump according to the invention
  • Figure 2 is a partial sectional view of part of the priming circuit of the pump of Figure 1
  • Figure 3 is an exploded perspective view 36
  • FIG. 1 partial illustrating the valve seat of the assembly 1 • suiva invention
  • Figure 4 is a longitudinal sectional view of the valve seat according to the invention
  • Figure 5 is a plan view.
  • the pump shown in FIG. 1 comprises a suction chamber 1 communicating with a discharge chamber 2, not shown, by means of a cell pump body 3.
  • the suction chamber 1 eg also communicates with the discharge chamber by priming circuit 4 capable of being closed by a valve comprising a seat 5 pierced with an orifice 6 and an elastic blade.
  • the seat 5 is mounted on the pump body in a threaded manner in a slide 8 formed on a priming element 9 of the pump body.
  • the seat 5 is in the form of an arc of a circle
  • the orifice 6 is of longitudinal shape and is bordered, on the opposite side to that where the blade 7 is embedded, with a heel 10 projecting towards the blade 7. From the 'other side of the orifice 6, seat 5 has two pins 11 cooperating with two holes in the blade, so as to embed it.
  • the blade 7 consists of a sensibleme rectangular part 13 intended to allow its embedding part 13 in which the holes 12 are formed, and of part 14 in the form of an isosceles triangle whose base is attached to one side of the part 13 Due to the narrowing of the width of the part 14 as the distance from the embedded part 13 increases, the flexibility of the part 14 increases.
