Description
Technical Field

Background
The high-energy liquid-phase fuel is filled in the body detonation warhead, the high-energy liquid-phase fuel is thrown into the air under the action of explosive detonation throwing driving, the high-energy liquid-phase fuel is atomized and mixed with the air to form a large-range active cloud cluster, and the active cloud cluster generates body detonation through secondary detonation of the explosive to release strong shock waves, wherein the shock wave power exceeds the explosive power of TNT with multiple times of mass, and the high-energy liquid-phase fuel is one of non-nuclear weapons with the largest power.
The improvement of the explosive power of the body detonation warhead mainly depends on the improvement of the energy of the internally filled fuel, and the improvement is reported in the literature "high power FAE liquid fuel optimization selection" (fire and explosive bulletin 2016, page 14 of 3 rd year): the metal powder is added into the liquid fuel, the liquid fuel and the metal powder are mixed to form the solid-liquid mixed fuel, and the energy of the fuel in the body detonation warhead can be greatly improved due to the high heat value of the metal powder. After mixing the solid-liquid phase mixed fuel, adding gelling agent to avoid the layering of the metal powder and liquid phase fuel mixture under the action of gravity.
The shell of the body detonation warhead is a cavity with sealing property inside, the top end is provided with a loading port, gelled solid-liquid phase mixed fuel is loaded through the loading port, and then the loading port is sealed. The sealing method used is as follows: the upper end face of the medicine loading opening is provided with an annular sealing groove, an annular sealing ring is arranged in the sealing groove, the upper end of the medicine loading opening is provided with a cover plate, and the cover plate tightly presses the sealing ring to realize sealing.
However, in the actual charging process, the solid-liquid phase mixed fuel and the gel are uniformly mixed in the kneader and then are poured into the warhead shell. To ensure filling, the fuel mixture is usually filled until it overflows. And cleaning the overflowing mixed fuel. However, the metal powder after gelation has a large adhesive force, and the metal powder outside the charging port and in the sealing groove is firmly adhered and agglomerated, so that it is difficult to completely clean the metal powder. The mixed fuel itself is sensitive to friction and shock, and metal powder that cannot be cleaned is generally not cleaned any longer for safety. The residual metal powder makes the upper end surface of the medicine filling opening uneven, the upper end of the medicine filling opening becomes uneven, and when the sealing ring and the upper end cover plate are installed at the upper end of the medicine filling opening, the cover plate and the end surface of the medicine filling opening are difficult to be in tight joint contact. After the assembly is completed, the sealing ring is annularly extruded to different degrees at each part upwards, the sealing ring is fully extruded at the convex part of the end face of the medicine charging port, the sealing ring can be sealed, and the sealing ring is not extruded at the concave part of the end face of the medicine charging port, so that the sealing ring cannot be sealed. Once a leak occurs, it will cause the warhead to fail.

The using method and the working principle of the invention are as follows:
the upper surface of the medicine charging port 1 is uneven, the sealing ring 3 is pressed by the cover plate in the original scheme, but the cover plate is a plane, when the cover plate is contacted with the uneven surface of the medicine charging port 1, the cover plate can only be contacted with the convex points of the medicine charging port 1, a gap is inevitably formed between the cover plate and the concave points of the medicine charging port 1, and the sealing ring between the cover plate and the concave points of the medicine charging port 1 cannot be compressed enough, so that the fitting degree between the sealing ring and the concave points is not enough. The sealing principle is that the sealing ring and the metal part in contact with the sealing ring have enough extrusion deformation, the sealing ring completely fits and fills the unevenness on the surface of the metal part, so that gas or liquid molecules cannot penetrate through a gap between the metal part and the metal part, and sealing is realized. Thus, when the seal ring is not sufficiently compressed at the concave point, the seal ring cannot be fitted, resulting in leakage.
The upper surface of the medicine charging opening 1 is still uneven, but the sealing ring 3 is tightly pressed by the pin 4, and the pin 4 is uniformly distributed in a circle, so that when the sealing ring 3 is contacted with the bulge on the upper surface of the medicine charging opening 1, the position of the pin 4 is correspondingly increased, the sealing ring 3 is sufficiently extruded, the sealing ring 3 and the bulge on the upper surface of the medicine charging opening 1 are sufficiently extruded and deformed, and the medicine charging opening can be sealed.
When the sealing ring 3 contacts with the dent on the upper surface of the medicine loading opening 1, the position of the pin 4 is correspondingly lowered, and the sealing ring 3 is sufficiently extruded, so that the sealing ring 3 and the dent on the upper surface of the medicine loading opening 1 have sufficient extrusion deformation, and the medicine loading opening can be sealed at the place. Namely, the pin 4 is correspondingly adjusted up and down according to the unevenness of the upper surface of the medicine charging port 1, and the unevenness is also achieved along with the corresponding up and down adjustment, and the final purpose is to ensure that the sealing ring 3 is also uneven with one circle of the sealing ring on the upper surface of the medicine charging port 1 under the extrusion action of the pin 4, and as a result of assembly, all parts with unevenness on one circle of the upper surface of the sealing ring 3 and the medicine charging port 1 are tightly attached, so that the circle of the sealing ring contacting with the medicine charging port 1 is sealed. And the seal between the sealing cover plate 2 and the sealing ring 3 is realized by radial extrusion between the sealing ring 3 and a second annular groove of the sealing cover plate 2.
The clearance between charge mouth 1 and sealed apron 2 owing to realized sealed between sealed apron 2 and the sealing washer 3, has also realized sealed between charge mouth 1 and the sealing washer 3 to realized sealed between charge mouth 1 and the sealed apron 2.
The pin 4 is driven by a spring 5, which generates a pressing force of the pin 4 against the sealing ring 3. After the spring 5 is used, although the pins 4 are distributed in different heights according to the projections and the depressions on the upper surface of the medicine loading port 1, the compression force of the spring 5 is determined according to the magnitude of elastic deformation thereof. Compared with the convex-concave uneven size of the pin 4, the elastic deformation of the spring 5 is too small and negligible, so that the pressing force of the pin 4 on the sealing ring 3 is almost kept consistent around the ring under the driving of the spring 5. At this moment with the biggest difference of original scheme, among the original scheme, 3 the ring by the packing force ring a week difference very big to lead to 3 rings of sealing washer to a week extrusion degree height difference, 3 rings of sealing washer can be sealed to a week extrusion part fully, 3 rings of sealing washer leak to a week extrusion insufficient department. In the scheme of the invention, the pressed force of the sealing ring 3 is uniform circumferentially, so that the sealing ring 3 is completely attached to the convex-concave part at the upper end of the medicine loading port 1 circumferentially by being pressed, and the point of insufficient pressing is avoided. Thereby realizing the end face sealing to the uneven end face.
Regarding the size ratio between the diameter of the second circular through hole of the sealing cover plate 2 and the width of the second annular groove of the sealing cover plate 2, consider as follows, when the diameter of the second circular through hole of the sealing cover plate 2 is too small than the width of the second annular groove of the sealing cover plate 2, the diameter of the pin 4 will be reduced because the diameter of the second circular through hole of the sealing cover plate 2 is too small, the extrusion of the pin 4 to the sealing ring 3 is changed from surface extrusion to point extrusion, the sealing ring 3 realizes the extrusion of the sealing ring 3 to the medicine loading port 1 mainly by means of the extrusion force of the upper end pin 4, therefore, when the upper end extrusion force of the sealing ring 3 is the point extrusion force, the upper end of the sealing ring 3 only locally generates extrusion concave deformation, and the whole generates warpage, and the deformation is generated. When only the upper end of sealing washer 3 is the face extrusion, sealing washer 3 steadily compresses under the extrusion, can not take place the warpage, and the steady transmission of the upper end extrusion force of sealing washer 3 is favorable to lower extreme sealing washer 3 and the sealed of charge mouth 1 to the extrusion of lower extreme sealing washer 3 to charge mouth 1. And when the diameter of the second circular through hole of the sealing cover plate 2 is too large than the width of the second annular groove of the sealing cover plate 2, the diameter of the pin 4 is enlarged due to the too large diameter of the second circular through hole of the sealing cover plate 2, the extrusion surface of the pin 4 to the sealing ring 3 is too large, when the upper surface of the medicine charging port 1 at the lower end of the sealing ring 3 is uneven, the sealing ring 3 is mainly attached to the upper surface of the medicine charging port 1 tightly by the corresponding unevenness of the sealing ring 3, and sealing is realized. However, when the extrusion surface of the pin 4 to the sealing ring 3 is too large, the sealing ring 3 is extruded in a plane in the covering plane of the pin 4, and the unevenness of the upper surface of the medicine loading port 1 at the lower end in the plane cannot be compensated by the unevenness of the pin. That is, when the pressing surface of the pin 4 is too large, a plurality of pins 4 can be adjusted according to the unevenness of the upper surface of the medicine loading port 1 in the covering surface, and one pin 4 cannot be adjusted according to the unevenness of the upper surface of the medicine loading port 1 in the covering surface, corresponding to the position occupied by one pin 4 in the plurality of pins 4 intended by the present invention. The design significance of the present invention cannot be achieved. It has been found through a number of experiments that the ratio of the diameter of the second circular through hole of the sealing cover plate 2 to the width of the second annular groove of the sealing cover plate 2 is 1: 1.4-1.7, the above problems can be avoided, and the above functions can be realized, so that the use requirements are met.
In this embodiment, the ratio of the diameter of the second circular through hole of the sealing cover plate 2 to the width of the second annular groove of the sealing cover plate 2 is 1: 1.4;
the ratio of the second annular groove width of the sealing cover plate 2 to the diameter of the rotary section of the third ring body of the sealing ring 3 is too small, the extrusion deformation of the sealing ring 3 to the second annular groove of the sealing cover plate 2 is too large, the assembly can hardly be completed, the ratio of the second annular groove width of the sealing cover plate 2 to the diameter of the rotary section of the third ring body of the sealing ring 3 is too large, the sealing ring 3 is insufficient due to the extrusion degree of the second annular inner wall and the outer wall of the sealing cover plate 2, and the sealing between the sealing ring 3 and the sealing cover plate 2 can not be realized. Through a large number of experiments, the ratio of the width of the second annular groove of the sealing cover plate 2 to the diameter of the revolution section of the third annular body of the sealing ring 3 is found to be 1: 1.2-1.4, the above problems can be avoided, the above functions can be realized, and the use requirements can be met.
In this embodiment, the ratio of the width of the second annular groove of the sealing cover plate 2 to the diameter of the turning cross section of the third annular body of the sealing ring 3 is 1: 1.2;
the ratio of the diameter of the fourth cylinder of the pin 4 to the diameter of the second circular through hole of the sealing cover 2 is too small,
the gap between the pin 4 and the second circular through hole of the sealing cover plate 2 is too large, once the pin 4 is inclined, the pin is easily clamped in the second circular through hole of the sealing cover plate 2, the pin 4 cannot move due to the driving of the spring 5 at the upper end, and the pin 4 cannot extrude the sealing ring 3 at the lower end, so that the sealing ring of the invention loses functions.
When the ratio of the diameter of the fourth cylinder of the pin 4 to the diameter of the second circular through hole of the sealing cover plate 2 is too large, the gap between the pin 4 and the second circular through hole of the sealing cover plate 2 is too small, and the frictional resistance of the pin 4 and the second circular through hole of the sealing cover plate 2 in movement is too large, so that the invention loses the function. It has been found through a number of experiments that the ratio between the diameter of the fourth cylinder of the pin 4 and the diameter of the second circular through hole of the sealing cover 2 is 1: 1.06-1.14, the above problems can be avoided, and the above functions can be realized, so that the use requirements are met.
In this embodiment, the ratio of the diameter of the fourth cylinder of the pin 4 to the diameter of the second circular through hole of the sealing cover plate 2 is 1: 1.06;
after the sealing cover plate 2 and the pressure plate 6 are assembled, the spring 5 is compressed, when the axial elastic force generated by the compressed spring 5 is too large, the axial elastic force generated by the spring 5 on the pin 4 is too large, the axial force generated by the pin 4 on the sealing ring 3 is too large, and the sealing ring 3 is easy to deform plastically due to too large deformation because of too large extrusion force, so that the sealing ring 3 fails. When the axial elastic force generated by the compressed spring 5 is too small, the axial elastic force generated by the spring 5 to the pin 4 is too small, the axial force generated by the pin 4 to the sealing ring 3 is too small, and the sealing ring 3 is easy to deform to be too small due to too small extrusion force, so that the sealing ring 3 and the medicine charging opening 1 are too small in extrusion degree and cannot be sealed. A large number of experiments find that after the sealing cover plate 2 and the pressing plate 6 are assembled, the spring 5 is compressed, and when the axial elastic force generated by the compressed spring 5 is 35-69N, the problems can be avoided, the functions can be realized, and the use requirement is met.
In this embodiment, after the sealing cover plate 2 is assembled with the pressure plate 6, the spring 5 is compressed, and the axial elastic force generated by the compressed spring 5 is 35.
The tightness tests of the scheme and the original scheme are carried out, ten warhead parts are selected respectively, 7 warhead parts are leaked after the ten warhead parts of the original scheme are charged, and 3 warhead parts are sealed completely. After ten warhead charges of the scheme of the invention are finished, 10 warhead charges are completely sealed.
The leakage-proof device based on the coaxiality measuring instrument is arranged at the upper end of the uneven end face of the medicine loading opening, the sealing rings are axially extruded by the pins which are uniformly distributed around the circumference in the circumferential direction, the pins around the circumferential direction are not connected, and each pin independently extrudes the sealing ring; the end face of the medicine filling opening is also provided with an independent pin to extrude the sealing ring to be tightly pressed with the medicine filling opening, so that sealing is realized.

The using method and the working principle of the invention are as follows:
the upper surface of the medicine charging port 1 is uneven, the sealing ring 3 is pressed by the cover plate in the original scheme, but the cover plate is a plane, when the cover plate is contacted with the uneven surface of the medicine charging port 1, the cover plate can only be contacted with the convex points of the medicine charging port 1, a gap is inevitably formed between the cover plate and the concave points of the medicine charging port 1, and the sealing ring between the cover plate and the concave points of the medicine charging port 1 cannot be compressed enough, so that the fitting degree between the sealing ring and the concave points is not enough. The sealing principle is that the sealing ring and the metal part in contact with the sealing ring have enough extrusion deformation, the sealing ring completely fits and fills the unevenness on the surface of the metal part, so that gas or liquid molecules cannot penetrate through a gap between the metal part and the metal part, and sealing is realized. Thus, when the seal ring is not sufficiently compressed at the concave point, the seal ring cannot be fitted, resulting in leakage.
The upper surface of the medicine charging opening 1 is still uneven, but the sealing ring 3 is tightly pressed by the pin 4, and the pin 4 is uniformly distributed in a circle, so that when the sealing ring 3 is contacted with the bulge on the upper surface of the medicine charging opening 1, the position of the pin 4 is correspondingly increased, the sealing ring 3 is sufficiently extruded, the sealing ring 3 and the bulge on the upper surface of the medicine charging opening 1 are sufficiently extruded and deformed, and the medicine charging opening can be sealed.
When the sealing ring 3 contacts with the dent on the upper surface of the medicine loading opening 1, the position of the pin 4 is correspondingly lowered, and the sealing ring 3 is sufficiently extruded, so that the sealing ring 3 and the dent on the upper surface of the medicine loading opening 1 have sufficient extrusion deformation, and the medicine loading opening can be sealed at the place. Namely, the pin 4 is correspondingly adjusted up and down according to the unevenness of the upper surface of the medicine charging port 1, and the unevenness is also achieved along with the corresponding up and down adjustment, and the final purpose is to ensure that the sealing ring 3 is also uneven with one circle of the sealing ring on the upper surface of the medicine charging port 1 under the extrusion action of the pin 4, and as a result of assembly, all parts with unevenness on one circle of the upper surface of the sealing ring 3 and the medicine charging port 1 are tightly attached, so that the circle of the sealing ring contacting with the medicine charging port 1 is sealed. And the seal between the sealing cover plate 2 and the sealing ring 3 is realized by radial extrusion between the sealing ring 3 and a second annular groove of the sealing cover plate 2.
The clearance between charge mouth 1 and sealed apron 2 owing to realized sealed between sealed apron 2 and the sealing washer 3, has also realized sealed between charge mouth 1 and the sealing washer 3 to realized sealed between charge mouth 1 and the sealed apron 2.
The pin 4 is driven by a spring 5, which generates a pressing force of the pin 4 against the sealing ring 3. After the spring 5 is used, although the pins 4 are distributed in different heights according to the projections and the depressions on the upper surface of the medicine loading port 1, the compression force of the spring 5 is determined according to the magnitude of elastic deformation thereof. Compared with the convex-concave uneven size of the pin 4, the elastic deformation of the spring 5 is too small and negligible, so that the pressing force of the pin 4 on the sealing ring 3 is almost kept consistent around the ring under the driving of the spring 5. At this moment with the biggest difference of original scheme, among the original scheme, 3 the ring by the packing force ring a week difference very big to lead to 3 rings of sealing washer to a week extrusion degree height difference, 3 rings of sealing washer can be sealed to a week extrusion part fully, 3 rings of sealing washer leak to a week extrusion insufficient department. In the scheme of the invention, the pressed force of the sealing ring 3 is uniform circumferentially, so that the sealing ring 3 is completely attached to the convex-concave part at the upper end of the medicine loading port 1 circumferentially by being pressed, and the point of insufficient pressing is avoided. Thereby realizing the end face sealing to the uneven end face.
Regarding the size ratio between the diameter of the second circular through hole of the sealing cover plate 2 and the width of the second annular groove of the sealing cover plate 2, consider as follows, when the diameter of the second circular through hole of the sealing cover plate 2 is too small than the width of the second annular groove of the sealing cover plate 2, the diameter of the pin 4 will be reduced because the diameter of the second circular through hole of the sealing cover plate 2 is too small, the extrusion of the pin 4 to the sealing ring 3 is changed from surface extrusion to point extrusion, the sealing ring 3 realizes the extrusion of the sealing ring 3 to the medicine loading port 1 mainly by means of the extrusion force of the upper end pin 4, therefore, when the upper end extrusion force of the sealing ring 3 is the point extrusion force, the upper end of the sealing ring 3 only locally generates extrusion concave deformation, and the whole generates warpage, and the deformation is generated. When only the upper end of sealing washer 3 is the face extrusion, sealing washer 3 steadily compresses under the extrusion, can not take place the warpage, and the steady transmission of the upper end extrusion force of sealing washer 3 is favorable to lower extreme sealing washer 3 and the sealed of charge mouth 1 to the extrusion of lower extreme sealing washer 3 to charge mouth 1. And when the diameter of the second circular through hole of the sealing cover plate 2 is too large than the width of the second annular groove of the sealing cover plate 2, the diameter of the pin 4 is enlarged due to the too large diameter of the second circular through hole of the sealing cover plate 2, the extrusion surface of the pin 4 to the sealing ring 3 is too large, when the upper surface of the medicine charging port 1 at the lower end of the sealing ring 3 is uneven, the sealing ring 3 is mainly attached to the upper surface of the medicine charging port 1 tightly by the corresponding unevenness of the sealing ring 3, and sealing is realized. However, when the extrusion surface of the pin 4 to the sealing ring 3 is too large, the sealing ring 3 is extruded in a plane in the covering plane of the pin 4, and the unevenness of the upper surface of the medicine loading port 1 at the lower end in the plane cannot be compensated by the unevenness of the pin. That is, when the pressing surface of the pin 4 is too large, a plurality of pins 4 can be adjusted according to the unevenness of the upper surface of the medicine loading port 1 in the covering surface, and one pin 4 cannot be adjusted according to the unevenness of the upper surface of the medicine loading port 1 in the covering surface, corresponding to the position occupied by one pin 4 in the plurality of pins 4 intended by the present invention. The design significance of the present invention cannot be achieved. It has been found through a number of experiments that the ratio of the diameter of the second circular through hole of the sealing cover plate 2 to the width of the second annular groove of the sealing cover plate 2 is 1: 1.4-1.7, the above problems can be avoided, and the above functions can be realized, so that the use requirements are met.
In this embodiment, the ratio of the diameter of the second circular through hole of the sealing cover plate 2 to the width of the second annular groove of the sealing cover plate 2 is 1: 1.7;
the ratio of the second annular groove width of the sealing cover plate 2 to the diameter of the rotary section of the third ring body of the sealing ring 3 is too small, the extrusion deformation of the sealing ring 3 to the second annular groove of the sealing cover plate 2 is too large, the assembly can hardly be completed, the ratio of the second annular groove width of the sealing cover plate 2 to the diameter of the rotary section of the third ring body of the sealing ring 3 is too large, the sealing ring 3 is insufficient due to the extrusion degree of the second annular inner wall and the outer wall of the sealing cover plate 2, and the sealing between the sealing ring 3 and the sealing cover plate 2 can not be realized. Through a large number of experiments, the ratio of the width of the second annular groove of the sealing cover plate 2 to the diameter of the revolution section of the third annular body of the sealing ring 3 is found to be 1: 1.2-1.4, the above problems can be avoided, the above functions can be realized, and the use requirements can be met.
In this embodiment, the ratio of the width of the second annular groove of the sealing cover plate 2 to the diameter of the turning cross section of the third annular body of the sealing ring 3 is 1: 1.4;
the ratio of the diameter of the fourth cylinder of the pin 4 to the diameter of the second circular through hole of the sealing cover 2 is too small,
the gap between the pin 4 and the second circular through hole of the sealing cover plate 2 is too large, once the pin 4 is inclined, the pin is easily clamped in the second circular through hole of the sealing cover plate 2, the pin 4 cannot move due to the driving of the spring 5 at the upper end, and the pin 4 cannot extrude the sealing ring 3 at the lower end, so that the sealing ring of the invention loses functions.
When the ratio of the diameter of the fourth cylinder of the pin 4 to the diameter of the second circular through hole of the sealing cover plate 2 is too large, the gap between the pin 4 and the second circular through hole of the sealing cover plate 2 is too small, and the frictional resistance of the pin 4 and the second circular through hole of the sealing cover plate 2 in movement is too large, so that the invention loses the function. It has been found through a number of experiments that the ratio between the diameter of the fourth cylinder of the pin 4 and the diameter of the second circular through hole of the sealing cover 2 is 1: 1.06-1.14, the above problems can be avoided, and the above functions can be realized, so that the use requirements are met.
In this embodiment, the ratio of the diameter of the fourth cylinder of the pin 4 to the diameter of the second circular through hole of the sealing cover plate 2 is 1: 1.14;
after the sealing cover plate 2 and the pressure plate 6 are assembled, the spring 5 is compressed, when the axial elastic force generated by the compressed spring 5 is too large, the axial elastic force generated by the spring 5 on the pin 4 is too large, the axial force generated by the pin 4 on the sealing ring 3 is too large, and the sealing ring 3 is easy to deform plastically due to too large deformation because of too large extrusion force, so that the sealing ring 3 fails. When the axial elastic force generated by the compressed spring 5 is too small, the axial elastic force generated by the spring 5 to the pin 4 is too small, the axial force generated by the pin 4 to the sealing ring 3 is too small, and the sealing ring 3 is easy to deform to be too small due to too small extrusion force, so that the sealing ring 3 and the medicine charging opening 1 are too small in extrusion degree and cannot be sealed. A large number of experiments find that after the sealing cover plate 2 and the pressing plate 6 are assembled, the spring 5 is compressed, and when the axial elastic force generated by the compressed spring 5 is 35-69N, the problems can be avoided, the functions can be realized, and the use requirement is met.
In this embodiment, after the sealing cover plate 2 is assembled with the pressure plate 6, the spring 5 is compressed, and the axial elastic force generated by the compressed spring 5 is 69N.
The tightness tests of the scheme and the original scheme are carried out, ten warhead parts are selected respectively, 7 warhead parts are leaked after the ten warhead parts of the original scheme are charged, and 3 warhead parts are sealed completely. After ten warhead charges of the scheme of the invention are finished, 10 warhead charges are completely sealed.
The leakage-proof device based on the coaxiality measuring instrument is arranged at the upper end of the uneven end face of the medicine loading opening, the sealing rings are axially extruded by the pins which are uniformly distributed around the circumference in the circumferential direction, the pins around the circumferential direction are not connected, and each pin independently extrudes the sealing ring; the end face of the medicine filling opening is also provided with an independent pin to extrude the sealing ring to be tightly pressed with the medicine filling opening, so that sealing is realized. After the installation is finished, the sealing ring correspondingly adjusts the shape of the sealing ring according to the protrusion and the depression of the end surface of the medicine loading port and is in close joint contact with the sealing ring, so that the sealing of the end surface with uneven surface is realized, and the use reliability of the warhead is ensured.
