As shown in Fig. 4-11, flap 2 includes flap pedestal 21 and the pressing plate 22 for being covered on 21 outer surface of flap pedestal, flap
21 inner surface of pedestal is the inclined-plane being adapted to drift ping 3, and 21 inner surface of flap pedestal is connect with 3 dovetail of drift ping, wherein flap pedestal
21 inner surfaces are equipped with dovetail groove 27, and there is the forked tail platform of adaptation in 3 outer surface of drift ping.
21 outer surface of flap pedestal is cylindrical surface, and 22 inner surface of pressing plate is bonded with the outer surface of flap pedestal 21；Pressing plate by
Clip plate 23 and outer plate 24 form, and have the window 25 being adapted to clip plate 23 on outer plate 24；Clip plate 23 and outer plate 24
The outer surface of flap pedestal 21, window 25 and 23 face of clip plate, 25 inner edge of window, clip plate are installed on by sunk screw 6
23 outer rims and 21 outer surface of flap pedestal cooperatively form one for installing the o-ring groove 26 of sealing ring 5, and sealing ring 5 is loaded on
In o-ring groove 26 and externally protrude out in 22 outer surface of pressing plate.
The cross-sectional shape of sealing ring 5 be it is various, as shown in Figure 10,5 cross section of sealing ring be triangle；Triangle
Sealing ring 5 and o-ring groove 26 cooperate, and can bear the moment impact of high pressure gas；With regard to delta-ring selection for height
Anti- gas explosion, highly resistance sulphur rubber can be selected in the operating conditions such as body, high sulfur resistive of calming the anger, this is that existing structure cannot achieve.
As shown in 12, the cross section of sealing ring 5 can also be " convex " font, the shapes such as trapezoidal.Preferably, valve channel, close
Seal 5 and clip plate 23 are racetrack.Wherein, the material of sealing ring 5 is rubber, plastics etc..
The present invention discloses the manufacturing method of above-mentioned flap, and above-mentioned flap pedestal 21 can cast, can forge, be cut using line
The inclined-plane that acquisition is adapted to drift ping 3 is cut, dovetail groove 27 is then processed on the inclined-plane；Then as shown in figure 19, by two valves
Valve pedestal 21 is mounted in the inclined surface of drift ping 3；Using the axis of drift ping 3 as the cylindrical surface of center Vehicle Processing flap pedestal 21.
Since the surfaces externally and internally of pressing plate is cylindrical surface, very difficult, the processing charges of sealed groove are processed on cylinder
It is expensive, thus the manufacturing method of pressing plate the following steps are included:
Step 1, flat platen 13 is made by the outer dimension that outer plate 24 is unfolded, as shown in Figure 13,14；Flat platen 13
Thickness=14 depth of t+ seal groove can prevent pressing plate seal groove 14 in pressing process from cracking preferably, t=4mm-6mm
Deformation.
Step 2, the seal groove 14 of racetrack is milled on flat platen 13, as shown in Figure 15,16；The depth of seal groove 14 by
Sealing ring size to be mounted cooperates to give.Pressing plate be flat condition when process seal groove 14, relative to utilize four
Axis linkage motion cutting center processes curved runway shape seal groove on cylindrical surface and more saves time and cost, and precision is higher.
Step 3, as shown in figure 17, multiple countersunk screw holes 15 are processed in 14 periphery of seal groove and interior enclose；
Step 4, as shown in figure 18, the curved surface pressing plate 16 that compacting obtains cylindrical surface, sealing are carried out to above-mentioned flat platen 13
Slot 14 is located at the inner surface of curved surface pressing plate 16；Pressing tool includes formpiston 17 and former 18, the radius and design of 17 cylinder of formpiston
Molding 21 outer circle radius surface of flap pedestal is consistent, the radius of 18 cylinder of former be equal to 21 outer circle radius surface of flap pedestal with it is above-mentioned
The sum of the thickness of pressing plate 22.
Step 5, as shown in Figure 19,20, flap pedestal 21 is mounted on drift ping 3, curved surface pressing plate 16 is covered on flap bottom
21 outer surfaces of seat, curved surface pressing plate 16 are fixedly connected by sunk screw 6 and countersunk screw holes with flap pedestal 21；
Step 6,16 outer surface of turning curved surfaces pressing plate, turning depth are greater than thickness of the curved surface pressing plate 16 at 14 slot bottom of seal groove
Degree, as shown in figure 20, the thickness for the part 19 for needing to be turned are greater than thickness of the curved surface pressing plate 16 at 14 slot bottom of seal groove, from
And as shown in Figure 20,21, so that curved surface pressing plate 16 is separated into 24 two parts of clip plate 23 and outer plate from seal groove 14；Inside and outside pressure
Plate cooperatively forms the uniform o-ring groove 26 of a size gap on flap pedestal 1, in addition, as needed, it can be to internal pressure
The wedge angle of plate 23 and outer plate 24 at o-ring groove 16 carries out blunt.
Step 7, unscrew peripheral sunk screw, remove outer plate 24；
Step 8, install sealing ring 5: sealing ring 5 is placed on 23 periphery of clip plate and is bonded with clip plate 23, is reinstalled outer
Pressing plate 24.
Similarly, when needing replacing sealing ring 5, it is only necessary to remove outer plate 24.
Inner-outer pressing plate sunk screw 6 and spring washer be tied on flap pedestal 21, can prevent inner-outer pressing plate and valve
Valve pedestal 21 falls off, while inside and outside pressing plate stress extruding being prevented to deform.
The dismountable sealing ring of the present invention can be accomplished to replace in time, groove dimensions standard, and interchangeability is high；And it dismantles
Mode is simple and fast.
Embodiment two
The difference between this embodiment and the first embodiment lies in: as shown in Figure 22,23,22 outer surface of pressing plate is sprayed in the present embodiment
Two circle hard alloy sealing surfaces 12, two circle hard alloy sealing surfaces 12 are located at the outside and inside of sealing ring 5.
After above-mentioned steps 5, first supersonic flame spraying hard alloy sealing surface 12, then to hard alloy sealing surface 12
It is ground, after hard alloy sealing surface 12 is ground, disassembles outer plate 24, then sealing ring 5 is installed, realize soft and hard seal
Separating treatment.The present embodiment power provides soft or hard dual-seal, is able to achieve the hard seal request of specific operation, while by replacement
Outer plate can fast online replacement hard alloy sealing surface 12.
Certainly, the present invention can also have other numerous embodiments, without deviating from the spirit and substance of the present invention,
Those skilled in the art can make various corresponding changes and modifications, but these corresponding changes and change according to the present invention
Shape all should fall within the scope of protection of the appended claims of the present invention.
