Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure containers, in particular to an installation device for a pressure charging valve. Background Art

[0002] After the assembly of products with high-pressure enclosed spaces is completed, the filling medium is generally filled into the cylinder through the pressure-charging valve to establish the required initial pressure to meet the performance requirements. The balancing device is a high-pressure container used on the rolling mill with the functions of roll balancing and roll separation. The pressure-charging valve of the general balancing device is installed at the tail of the cylinder body. Since the size of the sealing part of the pressure-charging valve is larger than the connection installation size, it is generally necessary to assemble the pressure-charging valve from the left end of the cylinder body to the bottom of the cylinder body during installation. During normal installation, the screws are screwed into the internal threaded hole of the pressure-charging valve and brought to the bottom of the cylinder body by gravity. However, when the length of the cylinder body is relatively large, it is very inconvenient for the operator to assemble the pressure-charging valve into the bottom of the cylinder body, and it is also easy to position it incorrectly.

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0032] A specific embodiment of the utility model is as follows Figure 1 As shown, a mounting device for a pressure charging valve 2 is disclosed, which is used to mount the pressure charging valve 2 on the bottom of a cylinder body 1 in a long cylinder body. The mounting device includes a mounting rod and a magnetic suction head.

[0033] The pressure charging valve 2 is installed at the center of the bottom of the cylinder body 1, is threadedly connected to the bottom of the cylinder body 1, and is sealed with the hole wall at the bottom of the cylinder body 1 by a sealing gasket.

[0034] Considering that the pressure-charging valve 2 is made of metal, the end of the mounting rod used to connect the pressure-charging valve 2 is connected to the magnetic head, so that the pressure-charging valve 2 can be fixed in the process of being sent to the bottom of the cylinder body 1, and can be separated from the pressure-charging valve 2 after being installed. After the pressure-charging valve 2 is sent to the bottom of the cylinder body 1, the pressure-charging valve 2 is aligned with the threaded through hole at the bottom of the cylinder body 1, and the pressure-charging valve 2 is tightened to fix the pressure-charging valve 2.

[0035] Considering the use of the charging valve 2 in the long cylinder body 1, in order to be able to send the charging valve 2 to the bottom of the long cylinder body 1, the first mounting rod 4 is used in this embodiment, that is, the form of a connecting rod 401 and a plurality of extension rods 402. The head of the connecting rod 401 is provided with a first threaded groove, one end of the extension rod 402 is provided with a stud corresponding to the first threaded groove of the head of the connecting rod 401, and the other end is provided with a second threaded groove identical to the connecting rod 401. When in use, align the stud of the extension rod 402 with the first threaded groove of the connecting rod 401 and install it. If multiple extension rods 402 are used, the extension rods 402 need to be installed one by one, end to end, until the end of the outermost extension rod 402 can extend out of the cylinder body 1. It should be noted that the diameter of the extension rod 402 is the same as that of the connecting rod 401, and the second threaded groove of the extension rod 402 is coaxial with the first threaded groove of the connecting rod 401. The number of extension rods 402 depends on the length of the cylinder body 1.

[0036] After stacking multiple extension rods 402 and installing them to the connecting rod 401, use the bottom of the connecting rod 401 to attract the first magnetic head 3, and the other end face of the first magnetic head 3 to attract the pressure valve 2, and extend the pressure valve 2 into the threaded through hole at the bottom of the cylinder body 1, screw it in, and the installation is completed. It should be noted that in order to ensure the centering of the pressure valve 2, when connecting, the first magnetic head 3 and the pressure valve 2 are coaxial with the connecting rod 401 and the extension rod 402.

[0037] like Figure 2 As shown, the mounting rod structure in this embodiment can also be a second mounting rod 4', that is, a telescopic rod structure, to save installation time and improve work efficiency. The telescopic rod has multiple levels, and it should be noted that the telescopic rod is made of metal.

[0038] Compared with the prior art, this embodiment adopts the form of superimposed or telescopic rods of the connecting rod 401 and the extension rod 402, so that the length of the part extending into the cylinder body 1 is increased, and it can adapt to cylinder bodies 1 of different lengths; it avoids the time-consuming and labor-intensive process of inverting the cylinder barrel during installation in the prior art, simplifies the installation process, and reduces labor intensity; the threaded grooves of the connecting rod 401 and the extension rod 402 are arranged along the axis to ensure a certain degree of centering of the charging valve 2; the charging valve 2 is sucked by a magnetic suction head, which facilitates the installation of the charging valve 2 and the detachment after installation.

[0039] Example 2

[0040] Considering that the charging valve 2 may be poorly aligned in Example 1, forcibly screwing it into the bottom of the cylinder body 1 will cause the threads of the charging valve 2 and the bottom of the cylinder body 1 to be damaged, affecting the use. Figure 3 As shown, this embodiment is provided with a conical structure with a centering characteristic. The upper part of the threaded through groove at the bottom of the cylinder body 1 is a rotating body hole, and the main body of the rotating body hole is a conical hole. A second magnetic suction head 3' is provided to match the bottom shape of the cylinder body 1, and the part connected to the charging valve 2 is conical. In order to make the entire device lightweight, the second magnetic suction head 3' is provided as a hollow structure.

[0041] When in use, the mounting rod is set according to the length of the cylinder body 1; the second magnetic head 3' is mounted on the bottom of the mounting rod, the bottom end of the second magnetic head 3' magnetically fixes the pressure-charging valve 2, the mounting rod is extended until the head exceeds the mouth of the cylinder body 1, and the second magnetic head 3' is inserted into the rotating body hole at the bottom of the cylinder body 1, so that the conical surface of the second magnetic head 3' fits with the conical surface at the bottom of the cylinder body 1, and the high degree of alignment between the pressure-charging valve 2 and the threaded through hole at the bottom of the cylinder body 1 is achieved. The external thread of the pressure-charging valve 2 is screwed into the bottom thread of the cylinder body 1 to complete the installation of the pressure-charging valve 2.

[0042] Compared with the prior art, this embodiment uses a conical structure for centering. A conical hole is set at the bottom of the cylinder body 1, and the conical surface of the second magnetic head 3' fits with the conical hole. The method is simple and can achieve high centering of the charging valve 2 and the threaded through hole at the bottom of the cylinder body 1.

[0043] Example 3

[0044] In order to further improve the centering degree of the device, this embodiment adds a centering structure 5 to the head of the mounting rod of embodiment 1. Figure 4 As shown, the centering structure 5 includes a claw 501 , a support rod 502 , a claw mounting head 503 , a support rod mounting head 504 and a first spring 505 .

[0045] The claw 501 is fixed on the claw mounting head 503 in the center. The claw 501 is an L-shaped rod, including a long rod and a short rod; the long rod is connected to the claw mounting head 503, and the short rod can clamp the outer edge of the cylinder body 1. Specifically, in order to ensure the centering and prevent the head of the mounting rod from being offset, the number of claws 501 is more than three. The claw mounting head 503 is fixed to the head of the mounting rod at the mouth of the cylinder body 1. The outside of the claw mounting head 503 is the support rod mounting head 504. One end of the support rod 502 is fixed to the support rod mounting head 504, and the other end is hinged to the center of the long rod. It should be noted that the number of support rods 502 is more than three. The support rod mounting head 504 can slide on the mounting rod. The inner side of the support rod mounting head 504 is connected to the first spring 505, and the other end of the first spring 505 is fixed to the claw mounting head 503.

[0046] Furthermore, if Figure 5 As shown, in order to lock the state of the centering structure 5, a locking structure 6 is also provided. The locking structure 6 includes a second spring 602, an elastic block 601 and an elastic block groove 603. A groove is provided inside the support rod mounting head 504, and the second spring 602 and the elastic block 601 are installed in the groove. An elastic block groove 603 is provided at the corresponding position of the head of the mounting rod. When the first spring 505 is in the natural state, the support rod 502 and the claw 501 structure are in a retracted state; when the support rod mounting head 504 is pushed inward, the first spring 505 is compressed, and when the claw 501 clamps the outer wall of the mouth of the cylinder body 1, the elastic block 601 of the support rod mounting head 504 is embedded in the elastic block groove 603 of the mounting rod, the position of the support rod mounting head 504 is fixed, and the positioning structure state is fixed.

[0047] Furthermore, in order to adapt to cylinder bodies 1 of different diameters, the long rod of the clamping claw 501 and the supporting rod 502 are both telescopic structures, and multiple clamping claws 501 or multiple supporting rods 502 can be extended at the same time.

[0048] When in use, first extend the charging valve 2 into the cylinder 1, and adjust the rod length of the mounting rod. Clamp the short rod of the claw 501 to the outer edge of the cylinder 1 at the same time, so that the head of the mounting rod is at the center of the mouth of the cylinder 1.

[0049] Compared with the prior art, the head of the mounting rod is provided with a centering structure 5, and the head of the mounting rod is positioned at the center of the mouth of the cylinder body 1 by extending the claw 501 to clamp the outer edge of the cylinder body 1 at the same time. In operation, it can be achieved by simply releasing the claw 501 and the support rod 502 at the same time. The long rod of the claw 501 and the support rod 502 are both telescopic structures, which can adapt to cylinder bodies 1 of different diameters. In order to reduce the burden of holding, a locking structure of the elastic block 601 and the elastic block groove 603 is provided.

[0050] Since the cylinder body 1 is relatively long, the installation device of the pressure-charging valve 2 needs to be relatively long. Compared with the prior art, the installation rod in the utility model is lengthened by using the extension rod 402 structure, or is extended by using the multi-stage telescopic rod structure, so that the length of the installation rod can adapt to cylinder bodies 1 of different lengths. At the same time, the centering mechanism is used to ensure the centering at the mouth of the cylinder body 1, and the conical structure is used to ensure the centering at the bottom of the cylinder body 1, so that the installation rod is simultaneously centered at both ends, so that the pressure-charging valve 2 can be accurately docked during installation, avoiding damage to the outer surfaces of the cylinder body 1 and the pressure-charging valve 2, and extending the service life of the pressure-charging valve 2 and the cylinder body 1.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
