Description

Technical Field

[0002] The background technology of floating sealing head for leakage test mainly involves sealing technology, testing technology and the combined application of the two. With the continuous improvement of the requirements for sealing performance in the industrial field, floating seal, as a high-performance sealing method, plays an increasingly important role in leakage testing. The floating sealing head is usually composed of a sealing ring and a support ring. The sealing ring is made of elastic material and can adapt to different working environments and medium characteristics. During the test, when the medium flows from the high-pressure area to the low-pressure area, the floating sealing head can automatically adjust its position to ensure effective sealing. In the leakage test, the application of the floating sealing head can significantly improve the accuracy and reliability of the test. The traditional fixed sealing head may cause sealing failure during the test due to factors such as medium pressure and temperature changes, while the floating sealing head can adjust adaptively to maintain a stable sealing effect. In addition, the design of the floating sealing head also takes into account the convenience and safety of the test, such as easy installation and disassembly, and overload protection.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] Embodiment 1: This embodiment is intended to promote the solution of the problem in the prior art that when the sealing head is installed, when encountering an installation body with inconsistent shapes, the staff needs to manually adjust it, which will waste a lot of time during the installation process. When the installation position needs to be changed, it needs to be adjusted again, which will greatly reduce the work efficiency of the staff. Please refer to Figure 1-Figure 5 A floating sealing head for leakage testing includes a sealing block 110, a limiting cylinder 130 is sleeved on the end of the sealing block 110, a fixing cylinder 120 is sleeved at the connection between the limiting cylinder 130 and the sealing block 110, a card slot 140 is opened in the middle of the sealing block 110, a buffer assembly 430 is installed on the side of the sealing block 110, the limiting cylinder 130 includes a rotating ring 210 connected to the card slot 140, a rotating plate 190 is connected to the side of the rotating ring 210, a support rod 200 is installed on the side of the rotating plate 190, one end of the support rod 200 is connected to the rotating ring 210, and the other end of the support rod 200 is connected to the card plate 180.

[0024] A snap-fit ​​groove 150 and a limiting groove 160 are provided on the side of the rotating plate 190. The snap-fit ​​groove 150 is provided on the side of the limiting groove 160. A spring 170 is fixedly installed in the middle of the limiting groove 160. One end of the spring 170 is fixedly connected to the inner wall of the limiting groove 160, and the other end of the spring 170 is fixedly connected to the clamping plate 180. The buffer assembly 430 includes a buffer block 220 fixedly installed on the inner wall of the sealing block 110, a connecting piece 230 is fixedly connected to the bottom of the buffer block 220, and a support column 240 is fixedly installed at the bottom of the connecting piece 230.

[0025] When the sealing head needs to be installed, the installation body can be directly clamped and fixed through the setting of the limiting cylinder 130, and there is no need for manual installation by the staff. When clamping, the installation body is first inserted into the card slot 140, and then because the diameter of the installation body is larger than the diameter of the card slot 140, the installation body will push the card plate 180 to move in the engaging groove 150, and at the same time, the other end of the card plate 180 will pull the spring 170 to move in the limiting groove 160. When it is necessary to replace a smaller installation body, since the spring 170 is pulled, when encountering a smaller installation body, the spring 170 will contract, thereby clamping the installation body, so that the sealing head can be fixed.

[0026] When the sealing head is tested, if it encounters a large impact force, the impact force will first impact the buffer block 220. At this time, the buffer block 220 will disperse part of the impact force. Then, when the impact force is large, the mounting rod 250 will be pushed by the support column 240, and then the mounting rod 250 will squeeze the rotating rod 330, and the rotating rod 330 will drive the squeezing rod 370 to squeeze the airbag 410. At this time, the gas in the airbag 410 will flow out through the air outlet 420, thereby buffering and protecting the sealing head.

[0027] In the present embodiment: when installing the sealing head, if encountering installation bodies of different specifications, the installation body can be clamped in time through the setting of the limiting cylinder 130, and the staff does not need to manually adjust it, which will greatly save the staff's time cost. Through the setting of the clamping plate 180, the engaging groove 150, the limiting groove 160 and the spring 170 in the limiting cylinder 130, the limiting cylinder 130 can be automatically adjusted according to the specifications of different installation bodies, which not only saves the working time of the staff, but also makes the operation easier, thereby greatly improving the work efficiency of the staff.

[0028] Embodiment 2: This embodiment is intended to promote the solution of the problem in the prior art that when the sealing head is tested, if a large impact force is encountered, the sealing head itself does not have a buffering effect, so the sealing head needs to be replaced, which greatly increases the economic cost. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 5 A mounting rod 250 is inserted into the side of the support column 240, a limit slot 260 is provided in the middle of the mounting rod 250, a connecting shaft 340 is fixedly installed in the middle of the limit slot 260, a rotating rod 330 is hinged on the side of the connecting shaft 340, and the rotating rod 330 is cross-hinged through the connecting shaft 340.

[0029] A movable groove 350 is opened in the middle of the rotating rod 330, and a fixed shaft 360 is slidably connected in the middle of the movable groove 350. The fixed shaft 360 is fixedly installed on the side of the extrusion rod 370.

A mounting column 300 is fixedly installed on the inner wall of the sealing block 110, and a fixing plate 290 is fixedly connected to the end of the mounting column 300. An air outlet 420 is opened in the middle of the fixing plate 290, and a fixed block 270 is fixedly installed above the fixing plate 290.

[0030] A slide groove 280 is opened in the middle of the fixed block 270, and the middle of the slide groove 280 is slidably connected to the slider 310. An extrusion cylinder 380 is fixedly installed in the middle of the fixed plate 290. A mounting groove 400 is opened in the middle of the extrusion cylinder 380. An airbag 410 is installed in the middle of the mounting groove 400. One end of the airbag 410 is connected to the air outlet 420, and the other end of the airbag 410 is fixedly connected to the extrusion plate 390. An extrusion rod 370 is fixedly installed at the end of the extrusion plate 390, and the extrusion rod 370 moves in the mounting groove 400.

[0031] In this embodiment: through the setting of the buffer component 430, when the sealing head encounters a large impact force during testing, it can be first buffered by the buffer block 220 to disperse a part of the impact force, and then through the mutual cooperation between the rotating rod 330, the airbag 410, the slider 310 and the slide groove 280, under the action of a large impact force, the impact force is dispersed through the mutual cooperation of a series of structures, thereby achieving a buffer protection effect, which can greatly improve the service life of the sealing head.
