Description

A kind of improvement structure of sand valve member

Technical field:

The present invention relates to a kind of water-jet cutting machine member.

Background technology:

Existing water-jet cutting machine sand valve member, comprise sand valve and the sand storage tank being connected with sand valve, sand storage tank is formed by metal manufacture, determined by its structure, one comes manufacturing cost high, two clean inconvenience, as for sand valve, as the patent of the multinomial relevant sand valve of being applied for before the applicant, limited by its structure, generally all with metal, process, this sand valve, although there is preventing return water, can regulate the function of suction force, but, complex structure, manufacturing cost is high, and, once there be water to pour in down a chimney, need to expend a large amount of man-hours clears up, safeguard that cost is high and inconvenient.

Summary of the invention:

Goal of the invention of the present invention is to provide a kind of simple in structure, low cost of manufacture, maintenance to be easy to the improvement structure of sand valve member.

The present invention realizes like this, comprise sand valve and the sand storage tank being connected with sand valve, its special feature be sand storage tank comprise transparent cylindrical shell, be arranged on transparent cylindrical shell with sand derive the bottom chew, with the top cover for sand import and exhaust outlet, bottom middle part is connected with bolt, pass on the bolt of top cover and be connected with nut, bolt, nut are fixedly connected with bottom, transparent cylindrical shell, top cover, and the import of sand valve is derived to chew with the sand of bottom and is connected.

During use, by adding sand for sand import toward sand storage tank, the effect of exhaust outlet be according to the sand in sand storage tank number regulate the air in sand storage tank, to guarantee that the air pressure in sand storage tank communicates with atmosphere, with guarantee that sand adds smoothly and importing sand valve in; While needing maintenance, clean sand storage tank, unclamp nut, just can easily the dismounting of sand storage tank also be cleaned easily.

For convenient fixedly sand storage tank, bottom and top cover are provided with hook, on the gib head of hook, are provided with raised face.In the time of fixedly, on corresponding fixed pedestal, be provided with two slots, then hook injected in slot, the bottom that makes the raised face of gib head cross slot, so that raised face plays the only effect of face, to prevent that sand storage tank is very freely shifted out in slot.

Here, sand valve comprises valve body, preventing return water mechanism, suction governor motion, valve body comprises cavity, be arranged on the leakage layer of sand plate of boring a hole with leakage sand in the middle part in cavity, be arranged on below layer of sand plate Lou with sand, derive perforation lead layer of sand plate, sand is derived the axis that sand perforation is leaked in punch-off, the edge that makes sand derive perforation is positioned at from leaking sand perforation and drops on outside the bottom edge of leading formed taper heap layer of sand plate, leading cavity below layer of sand plate is connected with sand and derives passage, preventing return water mechanism comprise under oblique and derive with sand the pipeline that passage is connected in taper, stop the pipe of face, be arranged on taper and stop the ball float on face, on duct wall on taper stops face, be provided with perforation, suction governor motion comprise under oblique and derive with sand the tracheae that passage is connected, screw thread is screwed in endotracheal screw, on the sidewall of screwed tracheae, be provided with pore.

During use, by screw, regulate the aperture of pore, regulate the size of suction, the present invention is connected with sand storage tank, sand in sand storage tank enters valve body, from the perforation of leakage sand, spill and drop on and lead layer of sand plate, until leak sand perforation in the top arrival of leading the conical sand heap of piling up on layer of sand plate, now, the edge of deriving perforation due to sand is positioned at from leaking sand perforation and drops on outside the bottom edge of leading formed taper heap layer of sand plate, the sand of sand heap can not derived perforation from sand and be flowed out, thereby form the effect of valve, when the water spout of water cutter is started working, the formed negative-pressure gas of spraying water drives the sand on conical sand heap to derive to bore a hole to move and flow out sand toward sand and derives perforation guiding water spout, the stable form of conical sand heap is destroyed, minimizing along with the sand of sand heap, sand in sand storage tank enters and leads layer of sand plate and then under the driving of negative-pressure gas, by sand, derives the perforation water spout that leads by leaking sand perforation continuously, when water cutter quits work, and under the effect of overbottom pressure, when water surprisingly permeates toward valve body direction along sand derivation passage, first water enter preventing return water mechanism, ball float is floated, water just the duct wall above taper stops face set perforation flow out and can not continue toward valve body infiltration, thereby effectively prevent the sand heap in water-wet valve body and cause sand valve ineffective.

Here, cavity is divided into tubular upper cavity, cavity in tubular, derive with sand the tubular lower chamber that passage is connected, middle part is arranged on the bottom of tubular upper cavity with the leakage layer of sand plate that leaks sand perforation and protrudes from the bottom surface of tubular upper cavity, with sand, derive the bottom surface that layer of sand plate is arranged on the bottom of cavity in tubular and protrudes from cavity in tubular of leading of perforation, the middle part that in tubular, the sealing socket of the upper end of cavity is fixed on tubular upper cavity lower end protrusion is with leaking on the leakage layer of sand plate of sand perforation, the upper end sealing shroud of tubular lower chamber is connected on the leading on layer of sand plate with sand derivation perforation that in tubular, protrude cavity lower end.

Tubular upper cavity, middle part are reinstated plastic monoblock with the leakage layer of sand plate one that leaks sand perforation and are processed, cavity in tubular, the layer of sand plate one of leading of deriving perforation with sand are reinstated plastic monoblock and are processed, tubular lower chamber, sand derive passage, oblique lower and derive with sand the pipeline that passage is connected in taper stop the pipe of face, tracheae one under oblique and that be connected with sand derivation passage is reinstated plastic monoblock and is processed.Employing plastic monoblock processes, can reduce costs significantly, like this, and once break down or impaired and can not normally use, integral replacing at low cost.

Compared with the prior art the present invention, has advantages of simple in structure, low cost of manufacture, maintenance easily and has preventing return water and adjustable suction.
