Description
Technical field
The present invention relates to a kind of water-jet cutting machine component.
Background technology
Existing water-jet cutting machine sand valve member, the sand storage tank comprising sand valve and be connected with sand valve, sand storage tank is formed by metal manufacture, determined by its structure, one to carry out manufacturing cost high, two clean inconvenience, as for sand valve, as before the applicant the multinomial patent about sand valve of applying for, limited by its structure, generally all form with intermetallic composite coating, this sand valve, although have preventing return water, the function of suction force can be regulated, but, complex structure, manufacturing cost is high, and, once there be water to pour in down a chimney, need clear up the man-hour of at substantial, safeguard that cost is high and inconvenient.
Summary of the invention
The modified node method that goal of the invention of the present invention is to provide that a kind of structure is simple, low cost of manufacture, maintenance are easy to sand valve member.
The present invention realizes like this, the sand storage tank comprising sand valve and be connected with sand valve, its special feature be sand storage tank comprise transparent cylindrical shell, be arranged on transparent cylindrical shell with sand derive chew bottom, with the top cover for sand import and exhaust outlet, bolt is connected with in the middle part of bottom, the part that this bolt passes top cover is connected with nut, bottom, transparent cylindrical shell, top cover are fixedly connected with by bolt, nut, 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 air in sand storage tank, to ensure that the air pressure in sand storage tank communicates with air, to ensure that sand adds smoothly and imports in sand valve; When needing maintenance, clean sand storage tank, unclamp nut, just can easily the dismounting of sand storage tank also be cleaned easily.
Conveniently fix sand storage tank, bottom and top cover are provided with hook, and the gib head of hook is provided with raised face.Time fixing, corresponding fixed pedestal be provided with two slots, then hook injected in slot, make the raised face of gib head cross the bottom of slot, so that raised face plays the effect in only face, be very freely shifted out in slot to prevent sand storage tank.
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 the middle part in cavity with the perforation of leakage sand, be arranged on below Lou layer of sand plate derive perforation with sand lead layer of sand plate, sand derives the axis that sand perforation is leaked in punch-off, make sand derive perforation edge be positioned at from leak sand perforation drop on lead layer of sand plate is formed taper heap bottom edge outside, the cavity of leading below layer of sand plate is connected with sand and derives passage, preventing return water mechanism comprise obliquely and derive with sand the pipe stopping face in pipeline that passage is connected with taper, be arranged on taper and stop ball float on face, the duct wall that taper stops above face is provided with perforation, suction governor motion comprise obliquely and derive with sand the tracheae that passage is connected, screw thread is screwed in endotracheal screw, the sidewall of screwed tracheae is provided with pore.
During use, the aperture of pore is regulated by screw, regulate the size of suction, the present invention is connected with sand storage tank, sand in sand storage tank enters valve body, spilling from the perforation of leakage sand and drop on leads layer of sand plate, till leaking sand perforation in the top arrival leading the conical sand heap that layer of sand plate is piled up, now, due to sand derive perforation edge be positioned at from leak sand perforation drop on lead layer of sand plate is formed taper heap bottom edge outside, the sand of sand heap can not be derived perforation from sand and be flowed out, thus form the effect of valve, when the water spout of water cutter is started working, the negative-pressure gas that water spray is formed drives the sand on conical sand heap to derive perforation toward sand and moves and flow out sand derivation perforation guiding water spout, the stable form of conical sand heap is destroyed, along with the minimizing of the sand of sand heap, sand in sand storage tank continuously by leak sand perforation enter lead layer of sand plate then under the driving of negative-pressure gas by sand derive perforation guiding water spout, when water cutter quits work, and under the effect of overbottom pressure, when water surprisingly permeates along sand derivation passage toward valve body direction, first water enter preventing return water mechanism, ball float is floated, just set from the duct wall that taper stops above face the perforation of water is flowed out and can not continue toward valve body infiltration, thus effectively prevents the sand in water-wet valve body from piling and causing sand valve ineffective.
Here, cavity is divided into tubular upper cavity, cavity in tubular, the tubular lower chamber that passage is connected is derived with sand, middle part is arranged on the bottom of tubular upper cavity with the leakage layer of sand plate leaking sand perforation and protrudes from the bottom surface of tubular upper cavity, the layer of sand plate of leading of deriving perforation with sand is arranged on the bottom of cavity in tubular and protrudes from the bottom surface of cavity in tubular, in tubular, the upper end sealing socket of cavity is fixed on the middle part of tubular upper cavity lower end protrusion 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 of protruding cavity lower end in tubular.
Tubular upper cavity, middle part are reinstated plastic monoblock with the leakage layer of sand plate one leaking sand perforation and are processed, cavity in tubular, the layer of sand plate one of leading of to derive perforation with sand are reinstated plastic monoblock and are processed, tubular lower chamber, sand derive passage, obliquely and with sand derive in pipeline that passage is connected with taper stop face pipe, obliquely and derive with sand tracheae one that passage is connected and reinstate plastic monoblock and process.Employing plastic monoblock processes, and can reduce costs significantly, like this, once break down or impaired and can not normally use, and can integral replacing at low cost.
The present invention compared with the prior art, have that structure is simple, low cost of manufacture, maintenance easily and there is the advantage of preventing return water and adjustable suction.
