Abstract
The utility model discloses a sheet type suction valve of a coating machine. The valve comprises a suction valve spring, a screw, a suction valve support, a support check ring, a suction valve support sleeve, a valve seat, a suction valve suction cup and a buffering ring, wherein the buffering ring and the suction valve suction cup form a whole, the suction valve suction cup adopts a circular truncated cone shape, and the shape of a contact part of the valve seat and the suction valve suction cup is matched with the shape of the suction valve suction cup. The sheet type suction valve of the coating machine is simple in structure and skillful in design, the sealing between the suction valve suction cup and the valve seat is better through improvement of the conventional sheet type suction valve, erosion of the suction valve suction cup and the screw by a high-pressure liquid is reduced in reciprocating motion of the high-pressure liquid, and the service life of the suction valve is prolonged.
Description
Technical field
The utility model relates to flush coater technical field, is specifically related to flush coater chip liquid sucting valve.
Background technology
High pressure airless spray equipment is the Special coating equipment that adopts high pressure painting technology.Engine drives eccentric free wheel to rotate, eccentric free wheel drives piston to move reciprocatingly, constantly liquid draw force feed is transported to diaphragm relief diaphragm and moves reciprocatingly and constantly draw coating in the pump housing, thereby in confined space, form high pressure, then release connection is in the spray gun trigger of coating pipe end, make high pressure coating stream force to form atomization by very tiny nozzle, thereby penetrate, reach coated article surface.The imbibition system of flush coater exists certain influence to the serviceability of flush coater, and most important in imbibition system be exactly liquid sucting valve, traditional plunger membrance combined type flush coater liquid sucting valve is opened the closure position of beating and is adopted alloy to be polished into chip, whole liquid sucting valve sucker is cone, be connected with screw rod, the side of cone contacts with valve seat, interruption closure by cone and valve seat in reciprocating motion is come imbibition and closure, valve seat carbide alloy partly adopts interference fit to compress into valve body, fastened by screw welding, in opening and closing process back and forth, because cone and valve seat are to contact, of long duration, liquid sucting valve sucker is caused to certain damage, sealing reduces, moment is closed, liquid also produces certain high pressure erosion to liquid sucting valve sucker and screw rod, liquid sucting valve and screw rod are short service life, complete machine serviceability is poor.
Utility model content
In order to address the above problem, the utility model provides flush coater chip liquid sucting valve, its object is: by the improvement to traditional chip liquid sucting valve, make liquid sucting valve sucker and valve base sealing better, in the high-pressure reciprocating motion process of liquid, reduce the erosion of liquid to liquid sucting valve sucker and screw rod, extend the service life of liquid sucting valve.
The utility model technical solution:
Flush coater chip liquid sucting valve, comprise liquid sucting valve spring, screw rod, liquid sucting valve support, support back-up ring, liquid sucting valve support casing, valve seat, liquid sucting valve sucker, it is characterized in that: described flush coater chip liquid sucting valve also comprises buffering ring, buffering ring and liquid sucting valve sucker are as a whole, described liquid sucting valve sucker is round table-like, and described valve seat and the shape of imbibition dish contact portion and the shape of liquid sucting valve sucker match.
Described buffering ring height is 3-8mm, and outside dimension is 6-12mm.
Described liquid sucting valve support is arranged on screw rod, and screw rod one end and liquid sucting valve sucker are fixed by nut, and the other end is provided with a nut and nut back-up ring.
Described liquid sucting valve spring is arranged between liquid sucting valve support and nut back-up ring.
It is outside that described support back-up ring is arranged on liquid sucting valve support, prevents that liquid sucting valve support from play occurring in reciprocating motion.
Described nut back-up ring and support back-up ring all adopt stainless steel material to make.
Described liquid sucting valve sucker, buffering ring and valve seat are made by wolfram steel carbide alloy.
The utility model beneficial effect:
The utility model is simple in structure, design ingeniously, by the improvement to traditional chip liquid sucting valve, make liquid sucting valve sucker and valve base sealing better, in the reciprocating motion of highly pressurised liquid, reduce the erosion of highly pressurised liquid to liquid sucting valve sucker and screw rod, extend the service life of liquid sucting valve.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, flush coater chip liquid sucting valve, comprise liquid sucting valve spring 3, screw rod 4, liquid sucting valve support 5, support back-up ring 6, liquid sucting valve support casing 7, valve seat 8, liquid sucting valve sucker 9, buffering ring 1, buffering ring 1 and liquid sucting valve sucker 9 are as a whole, liquid sucting valve sucker 9 is round table-like, the shape of valve seat 8 and liquid sucting valve sucker 9 contact portions and the shape 9 of liquid sucting valve sucker match, liquid sucting valve support 5 is arranged on screw rod 4, screw rod 4 one end and liquid sucting valve sucker 9 are fixed by nut, the other end is provided with a nut and nut back-up ring 2, liquid sucting valve spring 3 is arranged between liquid sucting valve support 5 and nut back-up ring 2, liquid sucting valve support outside is also provided with support back-up ring 6, prevent that liquid sucting valve support from play occurring in reciprocating motion.
Implementation column:
The utility model chip liquid sucting valve is installed in total valve body of flush coater, during flush coater work, eccentric wheel rotates and drives plunger to move back and forth, plunger drives solicitating film to move back and forth, liquid sucting valve moves reciprocatingly under the drive of solicitating film, pressure in imbibition valve body changes, by suction tube, draw spray coating liquor, spray coating liquor moves to spray tip from valve outlet, spray, flush coater chip liquid sucting valve also comprises buffering ring 1, buffering ring 1 and liquid sucting valve sucker 9 are as a whole, liquid sucting valve sucker 9 is round table-like, the shape of valve seat 8 and liquid sucting valve sucker 9 contact portions and the shape 9 of liquid sucting valve sucker match, 9 employings of liquid sucting valve sucker are round table-like to match with valve seat, effectively reduced the pressure problems of too of each reciprocating motion contact time point contact, buffering ring 1 is when liquid sucting valve moves back and forth, reduced the erosion of liquid to liquid sucting valve sucker and screw rod, liquid sucting valve support outer setting has support back-up ring 6, prevent that liquid sucting valve support from play occurring in reciprocating motion.
To sum up, the utility model produces a desired effect.
