Description

Technical Field

[0001] The utility model relates to the technical field of butterfly heads, in particular to an impact-resistant butterfly head. Background Art

[0002] The head is a boiler component in a pressure vessel, which is connected to the cylinder by welding and is usually used at both ends of the pressure vessel. The types of heads mainly include spherical heads, butterfly heads, bow bottom heads, etc. The butterfly head is also called a spherical head with folded edges. Because of its shallow depth and low requirements for stamping equipment and molds, it is easier to manufacture.

[0003] When the existing head is connected to the connecting pipe, it is often a single welding connection. Even if a small part is missed and not welded, the air tightness of the head will be insufficient and leakage will easily occur. In a closed space for a long time, there will inevitably be accumulation of air pressure and increase in internal temperature. When the internal air pressure is strong, expansion is likely to occur, causing deformation of the head. In addition, most general head seals do not have the function of heat dissipation. When the temperature inside the head seal is high, expansion and rupture will occur, which brings great inconvenience to users.

[0004] The existing patent (publication number: CN208778683U) is a heat dissipation butterfly head, which is fixed in a circumferential direction to the inner surface wall of the top of the butterfly head body of the head through the water inlet valve and the water outlet valve arranged on the outer surfaces of both sides of the water collecting tank, and the silicone tube connected between the water inlet valve and the water outlet valve. The circulation of water in the silicone tube reduces the temperature inside the butterfly head body of the head, which has the effect of heat dissipation, thereby reducing the expansion and rupture caused by the high temperature inside the butterfly head body of the head, and the clamping strip arranged on the inner surface wall of the butterfly head body near the bottom edge is clamped and connected with the clamping groove arranged on the outer surface of the connecting pipe near the top edge, thereby increasing the compression amount of the sealing ring, and then the butterfly head body of the head is welded to the connecting pipe, so as to improve the sealing performance of the butterfly head body of the head, thereby avoiding leakage due to insufficient sealing.

[0005] In view of the above problems, the existing patent provides a solution. However, during use, it lacks the function of providing support for the inner wall of the butterfly head. When the butterfly head is installed or transported, it is easy to cause it to deviate from the welding point of the external pipe during installation or collide during transportation, resulting in deformation, which greatly reduces the strength of the butterfly head.

[0006] Therefore, an impact-resistant butterfly head is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0031] The supporting mechanism 2 comprises a first supporting plate 201, an externally threaded column 202, a threaded sleeve 203, an extension tube 204, a fixed block 205, a telescopic rod 206, a supporting block 207 and a spring 208. The first supporting plate 201 is fixedly connected to the inner wall of the butterfly head body 1, the externally threaded column 202 is fixedly connected to the bottom of the first supporting plate 201, the threaded sleeve 203 is threadedly connected to the outer wall of the externally threaded column 202, multiple extension tubes 204 are fixedly connected to the outer wall of the threaded sleeve 203, multiple fixed blocks 205 are respectively fixedly connected to one side of multiple extension tubes 204, multiple telescopic rods 206 are respectively fixedly connected to one side of multiple fixed blocks 205, multiple supporting blocks 207 are respectively fixedly connected to one side of multiple telescopic rods 206, multiple springs 208 are respectively fixedly connected to one side of the supporting block 207, and the other side of the spring 208 is fixedly connected to the fixed block 205.

[0032] Specifically, Figure 5 As shown, a plurality of reinforcing bars 5 are fixedly connected to one side of the plurality of support rods 302 , and a plurality of stabilizing blocks 6 are fixedly connected to one side of the plurality of support rods 302 .

[0033] Specifically, Figure 3As shown, a groove 7 is provided inside the butterfly head body 1 , and the support block 207 is slidably connected inside the groove 7 .

[0034] Specifically, Figure 3 As shown, one side of the external thread column 202 is fixedly connected to a plurality of support bars 8 , and one side of the plurality of support bars 8 is fixedly connected to the inner wall of the butterfly head body 1 .

[0035] Specifically, Figure 4 As shown, a handle 9 is fixedly connected to one side of the support block 207 .

[0036] During use, when the butterfly head body 1 needs to be installed or transported, the threaded sleeve 203 can be screwed into the external threaded column 202. At the same time, the user can pull the support block 207 through the handle 9 to deform the spring 208, thereby extending the telescopic rod 206 and allowing the support block 207 to enter the interior of the butterfly head body 1. The pressure on the spring 208 is then released to allow the support block 207 to slide into the groove 7 to complete the support and fixation, thereby avoiding the outer wall of the butterfly head body 1 from being squeezed when welding, thereby affecting the docking of the welding points. The reinforcement strip 5 and the stabilizing block 6 can be used together to increase the strength of the support rod 302, thereby avoiding the support rod 302 from breaking when the butterfly head body 1 is impacted, and the support strip 8 improves the stability of the external threaded column 202.

[0037] Specifically, Figure 5 As shown, the reinforcement assembly 3 includes a second support plate 301, a support rod 302 and a reinforcement block 303. The second support plate 301 is fixedly connected to the inner wall of the butterfly head body 1, and multiple support rods 302 are fixedly connected to the top of the second support plate 301.

[0040] When in use, the reinforcement plate 10 can provide protection for the outer wall of the butterfly head body 1 and increase its strength. The second support plate 301 can provide support for the support rod 302 and the reinforcement block 303. When the top of the butterfly head body 1 collides or is squeezed, the reinforcement block 303 can increase the strength of the butterfly head body 1 and transfer the force to the support rod 302 and the second support plate 301. The honeycomb panel 401 and the rubber pad 402 are used in combination to disperse the impact force on the second support plate 301 and ensure the stability of the butterfly head body 1.

[0041] By adopting the above technical solution, a problem is solved in which an existing heat dissipation butterfly head lacks the function of providing support for the inner wall of the butterfly head during use. When the butterfly head is installed or transported, it is easy to cause it to deviate from the welding point of the external pipeline during installation or collide during transportation, resulting in deformation, which greatly reduces the strength of the butterfly head.

[0042] Working principle: When the present application is in use, the reinforcement plate 10 can provide protection for the outer wall of the butterfly head body 1 and increase its strength. The second support plate 301 can provide support for the support rod 302 and the reinforcement block 303. When the top of the butterfly head body 1 collides or is squeezed, the reinforcement block 303 can increase the strength of the butterfly head body 1 and transfer the force received to the support rod 302 and the second support plate 301. The honeycomb plate 401 and the rubber pad 402 are used together to disperse the impact force received by the second support plate 301 and ensure the stability of the butterfly head body 1. When the butterfly head body 1 needs to be installed or transported, the threaded sleeve 2 03 is screwed into the external threaded column 202. At the same time, the user can pull the support block 207 through the handle 9 to deform the spring 208, thereby extending the telescopic rod 206 and allowing the support block 207 to enter the butterfly head body 1. The pressure on the spring 208 is then released to allow the support block 207 to slide into the groove 7 to complete the support and fixation, thereby avoiding the outer wall of the butterfly head body 1 from being squeezed when welding, thereby affecting the docking of the welding points. The reinforcement strip 5 is used in conjunction with the stabilizing block 6 to increase the strength of the support rod 302, thereby avoiding the support rod 302 from breaking when the butterfly head body 1 is impacted. The support strip 8 improves the stability of the external threaded column 202.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
