Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure vessels, and particularly relates to a locking structure for a high-pressure vessel cylinder head. Background Art

[0002] Pressure vessels are widely used in fields such as rubber, medicine, ships, and dyeing. The locking device of the lid is a very important part of the pressure vessel. The sealing performance between the lid and the cylinder body of the pressure vessel is an important indicator for inspecting the quality of the pressure vessel.

[0003] Most of the existing high-pressure vessels are directly hinged to the side of the cylinder body through the cylinder head, so as to facilitate the opening and closing of the cylinder head. However, due to the hinged cylinder head, a gap needs to be separated between the sealing ring and the sealing groove of the cylinder head and the cylinder body to ensure the normal rotation and opening of the cylinder head. Therefore, the sealing ring and the sealing groove cannot be closely attached, affecting the sealing performance.

[0004] Therefore, we propose a locking structure for a high-pressure vessel cylinder head to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem of poor sealing effect in the prior art, and propose a locking structure for a high-pressure vessel cylinder head.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A locking structure for a high-pressure vessel cylinder head, including a cylinder body and a cylinder head that cooperate with each other. One side of the cylinder body is fixedly provided with a slide rail, and an installation block is slidably arranged on the slide rail. The cylinder head is hinged to the installation block.

[0008] The opposite sides of the cylinder body and the cylinder head are respectively fixedly connected with a first flange and a second flange. A plurality of through grooves are opened on the upper sides of the first flange and the second flange. One side of the first flange facing away from the second flange is fixedly connected with a plurality of side plates located on both sides of the through grooves. A bolt is hinged between the side plates on both sides of the through groove. The other end of the bolt extends to the outside of the second flange and is detachably connected with a nut. A synchronous component for synchronously rotating the bolts is arranged between the side plates of adjacent through grooves.

[0009] One side of the cylinder body facing the cylinder head is fixedly connected with a sealing ring, and a sealing groove for cooperating with the sealing ring is opened on one side of the cylinder head facing the rigid body.

[0010] Preferably, the synchronous component includes a rotating rod rotatably connected to the side surface of the side plate, and the rotating rod is coaxial with and connected to the rotating shaft of the bolt on the same side. The opposite ends of the two rotating rods between two adjacent through grooves are both connected with universal joints, and a connecting rod is connected between the two adjacent universal joints.

[0011] Preferably, a rubber ring is provided in the sealing groove.

[0012] Preferably, when the cylinder head and the cylinder block are closed and matched, the side surface of the sealing ring fits with the side surface of the sealing groove, and the end surface of the sealing ring fits with the rubber ring.

[0013] Preferably, a limiting block for restricting the angle of the cylinder head is fixedly connected to the mounting block.

[0014] Preferably, when the cylinder head and the cylinder block are closed and matched, the side surface of the limiting block fits with the side surface of the cylinder head.

[0015] In summary, the technical effects and advantages of the present utility model are as follows: For the locking structure of the high-pressure vessel cylinder head, the translation of the cylinder head relative to the cylinder block is realized through the cooperation of the mounting block and the slide rail, and the rotational opening of the cylinder head relative to the cylinder block is realized through the hinge connection between the mounting block and the cylinder head. Compared with the existing device, the problem that the sealing ring and the sealing groove cannot fit tightly is avoided, and the sealing effect is improved.

[0016] In addition, the synchronous rotation of multiple rotating rods is realized through the cooperation of the connecting rod and the universal joint, and then the synchronous rotation of multiple bolts is realized. Compared with the existing device, the need to rotate the bolts into the through groove every time the bolts are fixed by nuts is avoided. The locking efficiency is improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1 - 3, A locking structure for the cylinder head of a high-pressure container, including a cylinder block 1 and a cylinder head 2 that cooperate with each other. A slide rail 3 is fixedly provided on one side of the cylinder block 1. An installation block 4 is slidably provided on the slide rail 3, and the cylinder head 2 is hinged to the installation block 4.

[0024] On the opposite sides of the cylinder block 1 and the cylinder head 2 facing each other, a first flange 5 and a second flange 6 are respectively fixedly connected. A plurality of through grooves 7 are provided on the upper sides of the first flange 5 and the second flange 6. On the side of the first flange 5 facing away from the second flange 6, a plurality of side plates 8 located on both sides of the through groove 7 are fixedly connected. A bolt 9 is hinged between the side plates 8 on both sides of the through groove 7, and the other end of the bolt 9 extends to the outside of the second flange 6 and is detachably connected with a nut 10. A synchronizing component for synchronously rotating the bolts 9 is provided between the side plates 8 of adjacent through grooves 7. The bolts 9 correspond to the through grooves 7 one by one, and the number of bolts 9 is six. Too few bolts 9 will affect the safety and sealing performance of the high-pressure container, and too many bolts 9 will reduce the locking efficiency. Therefore, the scheme of using six bolts 9 is used for subsequent description.

[0025] Refer to Figure 4 On the side of the cylinder block 1 facing the cylinder head 2, a sealing ring 11 is fixedly connected, and on the side of the cylinder head 2 facing the rigid body, a sealing groove 12 for cooperating with the sealing ring 11 is provided.

[0026] For this locking structure of the high-pressure container cylinder head, when closing the cylinder head 2, first rotate the cylinder head 2 until the sealing ring 11 is parallel and directly opposite to the sealing groove 12. At this time, stop rotating the cylinder head 2 and start driving the cylinder head 2 to translate. Through the movement of the installation block 4 on the slide rail 3, the translation of the cylinder head 2 is realized. Until the sealing ring 11 is completely inserted into the sealing groove 12 and the side surface of the sealing ring 11 fits with the side surface of the sealing groove 12. At this time, rotate one of the bolts 9, and cooperate with the synchronizing component to realize the synchronous rotation of multiple bolts 9 until the bolts 9 are all located in the through grooves 7. At this time, the operator uses an electric torque tightening gun and fixes the nuts 10 one by one. That is, the locking of the cylinder head 2 is completed. When it is necessary to open the cylinder head 2, only need to operate the above steps in reverse order successively. It will not be elaborated here.

[0027] Refer to Figures 1 - 3 Since the bolts 9 may not be stably located in the through grooves 7 when not fixed by the nuts 10. At this time, one of the nuts 10 and the bolt 9 can be fixed first. Due to the effect of the synchronizing component, the other bolts 9 will be stably located in the through grooves 7, which is convenient for subsequent fixing.

[0028] The synchronizing component includes a rotating rod 13 rotatably connected to the side surface of the side plate 8, and the rotating rod 13 is coaxial with and connected to the rotating shaft of the bolt 9 on the same side. Thus, the bolt 9 drives the rotating rod 13 to rotate. Universal joints 14 are connected to the opposite ends of the two rotating rods 13 between two adjacent through grooves 7, and a connecting rod 15 is connected between the two adjacent universal joints 14. Through the cooperation of the connecting rod 15 and the universal joints 14, the synchronous rotation between the two rotating rods 13 is realized.

[0029] It should be noted that, for the sake of the aesthetics and safety of the device, the rotating rod 13, the universal joint 14, and the connecting rod 15 should neither protrude from the first flange 5 nor come into contact with the side surface of the cylinder block 1.

[0030] Refer to Figure 1 , Figure 3 , Figure 4 , a rubber ring 16 is provided in the sealing groove 12. When the cylinder head 2 and the cylinder block 1 are closed and fitted, the side surface of the sealing ring 11 is in contact with the side surface of the sealing groove 12, and the end surface of the sealing ring 11 is in contact with the rubber ring 16. The rubber ring 16 can fill the gap between the end surface of the sealing ring 11 and the sealing groove 12, further improving the sealing performance.

[0031] In order to limit the rotation angle of the cylinder head 2 and improve the stability and safety of the device, a limiting block 17 for limiting the angle of the cylinder head 2 is fixedly connected to the mounting block 4.

[0032] Since the sealing ring 11 needs to be parallel and directly facing the sealing groove 12 before the cylinder head 2 is closed. For the convenience of personnel to confirm the positional relationship, when the cylinder head 2 and the cylinder block 1 are closed and fitted, the side surface of the limiting block 17 is in contact with the side surface of the cylinder head 2.

[0033] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
