Description

Technical Field

[0001] The invention relates to the technical field of pressure vessel sealing heads, in particular to an adaptive pressure relief type pressure sealing head. Background Art

[0002] In the existing head technology, there are many structural forms of the head, for example, convex, conical, flat or combined structures, and there are also many mechanical mechanisms of the existing head, for example: "A buffer device for a pressure vessel head" disclosed in the publication (announcement) number: CN220792033U, the technical scheme includes: a head body, an extension tube is arranged at the bottom of the head body, and a top plate is arranged at one end of the extension tube close to the head body, a bottom plate is arranged at one end of the extension tube away from the top plate, a cavity is arranged inside the extension tube between the top plate and the bottom plate, and a flange is arranged at one end of the outer wall of the extension tube away from the head body, a limiting ring for limiting the position of the head body is arranged at the other end of the flange, and a buffer plate for sealing the opening of the pressure vessel is arranged inside the limiting ring. The buffer device disclosed in the present application can buffer the pressure inside the pressure vessel exerted on the head, reduce the pressure inside the pressure vessel exerted on the head body, avoid the trouble of damage to the head due to greater pressure caused by increased pressure inside the pressure vessel, increase the service life of the pressure vessel head, and realize protection of the pressure vessel head.

[0003] For example: the "head with a pressure adaptive adjustment structure" disclosed in the publication (announcement) number: CN218510421U, the technical solution includes a head body, a top cover is installed on the top of the head body, and a connecting rod is fixedly connected to the center position of the inner top of the top cover, the bottom end of the connecting rod is fixedly connected to an air plug, a connecting seat is installed on the bottom end of the head body, and the bottom end of the side surface of the connecting seat is provided with an external thread, a groove is provided at the center of the side surround of the connecting seat, and a limiting ring is fixedly connected to the top of the connecting seat. The head with a pressure adaptive adjustment structure described in the utility model is connected to the pipeline by an external thread during use. During the use of the pipeline, when the internal air pressure of the pipeline is too high or too low, the internal air pressure will push the air plug, thereby driving the top cover to move along the groove under the action of the connecting rod, thereby changing the use space of the top cover, alleviating the internal air pressure, and bringing better use prospects.

[0004] In addition to ensuring the pressure resistance of the pressure head, the above technical scheme also needs to ensure the pressure relief capacity of the pressure head. For example, the adaptively adjustable pressure head in the above technical scheme has the function of adaptively adjusting the pressure inside the pressure head. When the pressure inside the head is too high, the excess pressure can be released by adaptive adjustment. However, the structural design in the above technical scheme is relatively simple, and adaptive adjustment is achieved only through threads and air plug structures. The overall structural design is not comprehensive enough, and the threaded structure needs to be manually adjusted, which is not convenient to use.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a pressure relief pressure head with a reasonable structure and capable of realizing adaptive adjustment. Summary of the invention

[0016] Furthermore, the movable sealing plate and the fixed sealing plate have the same thickness, and the first pressure relief hole and the gas blocking rod have the same length, so that the gas blocking rod is adapted in size and pressed into the first pressure relief hole.

DETAILED DESCRIPTION

[0028] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, an adaptive pressure relief pressure head comprises an end cover head 1, a fixed sealing plate 2 is correspondingly installed in the end cover head 1, a first pressure relief hole 3 is correspondingly arranged on the fixed sealing plate 2, and a support rod 4 is correspondingly installed between the fixed sealing plate 2 and the upper end of the end cover head 1, and a movable sealing plate 5 is correspondingly installed on the upper end surface of the fixed sealing plate 2, a rod hole 6 is correspondingly arranged on the movable sealing plate 5, and the support rod 4 passes through the rod hole 6 so that the movable sealing plate 5 is correspondingly placed on the upper end surface of the movable sealing plate 5;

[0030] A spring member 7 is correspondingly installed between the upper end surface of the movable sealing plate 5 and the end cover head 1, and a gas blocking rod 8 corresponding to the position and size of the first pressure relief hole 3 is arranged on the lower end surface of the movable sealing plate 5. The movable sealing plate 5 is correspondingly pressed on the fixed sealing plate 2 under the action of the spring member 7, and the gas blocking rod 8 is correspondingly pressed into the first pressure relief hole 3 to block the first pressure relief hole 3 as a whole;

[0031] A linkage rod 9 is also installed on the upper end surface of the movable sealing plate 5, and the linkage rod 9 passes through the end cover head 1 upward, and the rod end of the linkage rod 9 is correspondingly installed with a gas blocking plate 10, and the upper end of the end cover head 1 is correspondingly provided with a mounting groove 11 corresponding to the position of the gas blocking plate 10. When the spring member 7 presses the movable sealing plate 5 as a whole, the linkage effect of the linkage rod 9 makes the gas blocking plate 10 correspondingly pressed in the mounting groove 11;

[0032] In addition, second pressure relief holes 12 are correspondingly provided in the mounting groove 11 and on the air blocking plate 10, and the positions of the second pressure relief holes 12 in the mounting groove 11 and the second pressure relief holes 12 on the air blocking plate 10 are staggered. When the air blocking plate 10 is pressed tightly in the mounting groove 11, the second pressure relief holes 12 at the upper and lower positions are correspondingly disconnected, and when the air blocking plate 10 moves upward, so that a gap appears between the air blocking plate 10 and the mounting groove 11, the second pressure relief holes 12 at the upper and lower positions are correspondingly connected.

[0033] The spring component 7 is correspondingly sleeved on the outside of the support rod 4, the support rod 4 supports the fixed sealing plate 2, and the spring component 7 presses the movable sealing plate 5; the support rods 4 are evenly distributed at the edge positions of the fixed sealing plate 2, and the support rods 4 are correspondingly provided with six evenly spaced ones; the position of the spring component 7 is set accordingly.

[0034] The end of the air blocking rod 8 is set as a concave cone structure, and the air blocking rods 8 are evenly distributed; the first pressure relief holes 3 on the fixed sealing plate 2 are evenly arranged in annular intervals, and two circles are correspondingly arranged; and the air blocking rods 8 on the movable sealing plate 5 are correspondingly arranged.

[0035] The air blocking plate 10 and the second pressure relief holes 12 in the mounting groove 11 are arranged on the same circumference in upper and lower positions, but the positions are staggered accordingly, and three of them are arranged.

[0036] The movable sealing plate 5 and the fixed sealing plate 2 have the same thickness, and the first pressure relief hole 3 and the gas blocking rod 8 have the same length, so that the gas blocking rod 8 is pressed into the first pressure relief hole 3 with a matching size.

[0037] like Figure 2 As shown, when the pressure head of the present invention is subjected to a larger airflow in the pressure vessel, the airflow will first press against the fixed sealing plate. The fixed sealing plate itself is fixed on the side wall of the end cover head and is supported and fixed by the support rod, and has a good pressure resistance. Therefore, the airflow will press against the first pressure relief hole of the fixed sealing plate. A gas blocking rod is correspondingly installed in the first pressure relief hole. When the force of the pressure airflow is greater than the spring force on the movable sealing plate, the pressure airflow will gradually push the gas blocking rod upward. When the gas blocking rod is pushed up, the movable sealing plate is also pushed up accordingly. On the one hand, an airflow gap is formed between the movable sealing plate and the fixed sealing plate, and the incoming pressure airflow moves upward from the airflow gap.

[0038] On the other hand, a linkage rod is further provided at the upper end of the movable sealing plate, and an air blocking plate is installed at the rod end of the linkage rod. The air blocking plate is also pressed correspondingly in the mounting groove under the action of the spring force. When the movable plate moves upward, the air blocking plate is also driven to move upward under the action of the linkage rod. Second pressure relief holes are provided in both the air blocking plate and the mounting groove, and the positions of the upper and lower second pressure relief holes are different. After a gap is synchronously generated between the air blocking plate and the mounting groove, the upper and lower second pressure relief holes are opened accordingly. Figure 2 As shown, the pressure airflow enters the gap from the second pressure relief hole in the installation groove, and then is discharged from the second pressure relief hole on the air blocking plate to release the pressure.

[0039] When the pressure is discharged and the internal air flow pressure is less than the elastic force of the spring part, the movable sealing plate will be pressed down by the spring part, so that the movable sealing plate is pressed against the fixed sealing plate, and the air blocking rod is blocked in the first pressure relief hole, thereby sealing the first pressure relief hole. At the same time, under the action of the linkage rod, the air blocking plate is also pressed in the installation groove, and the air blocking plate and the second pressure relief hole in the installation groove are themselves misaligned. After the air blocking plate is pressed, the second pressure relief hole is also blocked accordingly, thereby achieving the blocking of all pressure relief holes. The structural setting is very ingenious and reasonable.

[0040] The present invention can cleverly realize the adaptive release of pressure airflow and pressure resetting in the pressure vessel through the coordination of the fixed sealing plate, the movable sealing plate, the air blocking rod, the air blocking plate, the mounting groove and the pressure relief hole. The overall structure is very clever and reasonable and easy to use.

[0041] The technical solution in the present invention is a dual pressure relief structure, which is not only provided with a first pressure relief hole, but also with a second pressure relief hole. Different pressure relief mechanisms have different pressure relief methods, and the structural setting is ingenious; in the present invention, the fixed sealing plate has good pressure resistance under the action of the support rod, and a movable sealing plate is arranged on the basis of the fixed sealing plate and the support rod, and a first pressure relief hole and a matching air blocking rod are correspondingly arranged, which can realize the coordination between the fixed sealing plate and the movable sealing plate to realize adaptive pressure relief.

[0042] The movable sealing plate in the present invention is also installed with a corresponding air blocking plate through a linkage rod, and a corresponding installation groove for installing the air blocking plate is set, and a second pressure relief hole with staggered positions is set. The cooperation of the two can realize the adaptive pressure relief work of the second pressure relief hole, and the structural design is reasonable.

[0043] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
