Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face combines and is specifically illustrating, and this utility model is expanded on further.
See shown in Fig. 1 to Fig. 4, the utility model discloses the pneumatic moushroom valve of reciprocating swing type, including main valve body 10, secondary valve
Body 20, middle valve body 30, valve disc 40, valve seat 50, connecting rod 60, valve rod 70, rocking bar 80, centering type cylinder 90 and support 100, right
The outfan of Chinese style cylinder 90 is connected with rocking bar 80, and drives rocking bar to rotate；The bottom of main valve body 10 is provided with purge hole (in figure not
Draw), middle valve body 30 is arranged between main valve body 10 and auxiliary valve body 20, and and the junction of main valve body 10 and auxiliary valve body 20 between
It is provided with pad 110；The other end of centering type cylinder 90 is fixed on support 100；Valve rod 70 extend into valve pocket through main valve body 10
In, one end of valve rod 70 is connected with rocking bar 70 by screw 120, and the other end is connected with connecting rod 60 by screw 120；Connecting rod
The other end of 60 is connected with valve disc 40, and drives valve disc to rotate；Valve rod 70 is provided with ears stop pad with the junction of connecting rod 60
Circle 130；Being provided with packing seal letter between valve rod 70 and main valve body 10, packing seal letter is by low leakage filler 140, filler pressing sleeve
150 and hold-down grid 160 form, hold-down grid 160 is bolted on main valve body 10；Valve rod 70 is provided with step
71；Thrust washer 170 and sliding bearing 180 it is provided with between valve rod 70 and main valve body 10；Moushroom valve also includes a spring preloading device,
Spring preloading device is for sealing valve disc, and spring preloading device is by two spring bases 190 and is arranged on two springs
Spring 200 between seat 190 forms；The one end of two springs withstands on valve disc.
This utility model uses roomy sealing surface of seat, it is ensured that efficient sealed, reveals grade and meets ASMEB16.104 VI
Level requirements above, sealing property is higher than industrial standard, and distribution of forces area is big, it is little to wear and tear；Sealing surface vertical fluid direction,
Valve abrasion in the direction of flow and erosion do not interfere with sealing, it is achieved longer seat life is long, replaceable feature, uses special dress
Join process means to realize cooperation tight between different materials and fix.
Operationally, centering type cylinder drives rocking bar to rotate to this utility model, and rocking bar drives connecting rod work, connecting rod band
Dynamic valve disc reciprocally swinging, can shred the solid dielectric by valve, strengthens the automatically cleaning ability of valve seat；Often switch once, valve disc
Automatically an angle is rotated, it is achieved self-grind is from polishing function, and on-off times is the most, and sealing property is the best, can expire well
Foot valve is frequently opened required；Seal surface automatically derives grinding pairing along with the opening and closing of valve such that it is able to long
Phase keeps good sealing property, it is provided that excellent sealing life, the most easily safeguard.
It is efficient that this utility model spring preloading device has initial sealing power, it is possible to auxiliary valve disc seals, and stops material to enter
Enter to abrade sealing surface；Also have enough flying ability to adapt to high temperature, low temperature and the environment of high/low temperature alternation, it is to avoid Yin Wen
Degree change causes the possibility of spool bite, locking or serious leak, compensates valve member abrasion, it is ensured that seal tight closing.
This utility model uses full-bore structure, does not hinder medium to circulate, and discharge coefficient is big, and pressure drop is little, stops the feelings that build the pressure
Condition occurs.
This utility model uses open valve pocket structure, and inner chamber is without closing space, and purge hole is located at body base, can make thin
The media such as little granule are freely discharged and are not produced accumulated plugging；Owing to valve space is big, each shuttling movement of valve disc can be clear
Removing or agitation medium, rocking bar bias designs interior media when making valve opening and becomes eddy current shape to move, and prevents bank in valve pocket
The long-pending action caused is not smooth, thus realizes internal self-cleaning function.
Being integrally provided with step on valve rod, when hold-down grid is removed or extremely boosts in valve chamber, valve rod will not spray,
Low leakage filler, the simultaneously thrust washer between valve rod and valve body can be changed online, it is possible to form the primary seal at valve rod, in fall
Avoid the gathering of electrostatic, polishing after gasket surface hardening while low friction, then coordinate sliding bearing effectively to reduce
Valve operation moment of torsion；Lock washer with double ears between valve rod and connecting rod makes screw to rotate, and reaches locking purpose.
Centering type cylinder tail end is fixed on support, and tail end centering type fixed structure can reduce cylinder piston pole pair cylinder body
Horizontal force, optimize cylinder piston and the air-proof condition of piston rod, increase the service life；Prop up fixing also can the simplification of tail end
Shelf structure.
Shown in Figure 5, valve rod uses eccentric setting, and valve disc uses centering type air cylinder driven, by transporting cylinder
Dynamic and dynamic analysis, show that the power transmission effect of cylinder is directly proportional to sin θ, and drive line angle θ more great institutions is the most laborsaving, drive line angle θ
Too small (less than minimum limit value), mechanism is by self-locking；Therefore it is eccentric structure by stem design, deviates with valve body centrage a, b
Distance A, B, make cylinder have bigger drive line angle when initial position C point, reduce power output；When final position C ' puts, drive line angle is not
Can be the least, it is to avoid self-locking；Valve rod eccentric structure also makes rocking bar extended length simultaneously, it is possible to provide bigger kinetic moment drives valve
Dish.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also
Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model
Claimed scope is defined by appending claims and equivalent thereof.
