Description

Technical Field

[0001] This utility model relates to the field of sleeve sealing valve technology, and in particular to a sleeve sealing valve adjustment device. Background Technology

[0002] A bushing is an insulating device used to introduce a live conductor into electrical equipment or through a wall. The former is called an electrical bushing, and the latter a wall bushing. Bushings are commonly used in building basements and are iron rings used to protect pipes or facilitate pipe installation. Bushings are classified into rigid bushings, flexible waterproof bushings, steel pipe bushings, and sheet metal bushings, etc. When used in sealing valves, the flow rate can be adjusted via a regulating device.

[0003] As shown in the reference case "An Intelligent Dynamic Balancing Electric Regulating Valve" (publication number CN216344140U), by setting a first sealing cover plate, a second sealing cover plate, a sealing sleeve, a valve pipe, a valve stem, a valve plate, and a manual valve, the first and second sealing cover plates facilitate sealing, while the valve stem, valve plate, and manual valve allow for manual adjustment as needed, achieving a user-friendly effect.

[0004] According to the above references, the device uses a pressure gauge to facilitate real-time observation of water pressure and allows for further adjustment using the control box to achieve water pressure balance. A flow meter makes the flow rate at the inlet and outlet of the regulating valve visible during operation. However, when adjusting the flow rate by replacing the sleeve inside the sleeve-sealing valve, the replacement efficiency is not ideal, affecting the regulating effect of the sleeve-sealing valve, making sleeve replacement inconvenient, and reducing the overall effectiveness of the sleeve-sealing valve. Utility Model Content

[0005] Therefore, it is necessary to provide a sleeve sealing valve adjustment device to address the problem of inconvenience in replacing the sleeve.

[0006] The device includes a valve plate with a valve cover mounted on its top; a replacement mechanism, which is disposed on the inner wall of the valve plate to replace the sleeve inside the sleeve-sealed valve and to adjust the flow rate of the sleeve-sealed valve; wherein, the replacement mechanism includes a sleeve body that is snapped into the inner wall of the valve plate, and two locking blocks are slidably connected to both sides of the inner wall of the valve plate, with two compression springs disposed between one side of the locking block and the valve plate, and the other side of the locking block penetrating the valve plate and embedded in the inner wall of the sleeve body.

[0007] In one embodiment, the replacement mechanism further includes a groove formed at the top of the locking block, the top of the locking block extending through the outer wall of the valve plate. The groove can increase the friction at the top of the locking block, facilitating the sliding of the two locking blocks within the valve plate.

[0008] In one embodiment, the two ends of the compression springs respectively penetrate through the inner walls of the locking block and the valve plate. The grooves in the locking block and the valve plate can position and guide the two compression springs to prevent them from bending.

[0009] In one embodiment, a connecting ring is fixedly connected to the bottom end of the sleeve body, and the bottom end of the connecting ring is embedded in the inner wall of the valve plate.

[0010] In one embodiment, a sealing ring is fixedly connected to the inner wall of the valve plate, and the inner wall of the sealing ring is in contact with the connecting ring.

[0011] In one embodiment, a retaining ring is installed at the bottom end of the sleeve body, and a sealing sleeve is installed in the middle of the inner wall of the valve plate, with the retaining ring fitting against the sealing sleeve.

[0012] In one embodiment, the diameter of the retaining ring and the sealing sleeve is smaller than the diameter of the connecting ring, allowing for double-layer sealing via the sleeve body.

[0013] In one embodiment, the top of the valve cover is fitted with several evenly arranged fixing bolts, one end of which passes through the valve cover and is threadedly connected to the valve plate.

[0014] Beneficial effects

[0015] 1. In the above-mentioned sleeve sealing valve regulating device, the sleeve body is installed on the inner wall of the valve plate, and two locking blocks slide inside the valve plate. The supporting force generated by the compression spring causes one end of the locking block to be embedded in the sleeve body, which can limit the installation of the sleeve body. The grooves at the top of the two locking blocks can adjust and control the position of the locking blocks, and the sleeve body can be quickly disassembled and replaced. The grooves can increase the friction at the top of the locking blocks, making it easier to control the locking blocks. The two ends of the two compression springs are respectively installed in the locking blocks and the valve plate, which can guide the compression springs, making it easier to replace the sleeve and improve the flow regulation effect of the sleeve sealing valve.

[0016] 2. The connecting ring at the bottom of the sleeve body can be embedded in the valve plate to clamp the sleeve body. The inner wall of the sealing ring in the valve body contacts the connecting ring, and the top of the sealing ring contacts the bottom of the sleeve, which can seal the connection between the sleeve body and the valve plate. The retaining ring in the middle of the bottom of the sleeve body fits into the valve body, which can install the sleeve body. It can cooperate with the sealing sleeve to seal the sleeve body. The fixing bolts can install the valve cover on the valve plate, and the sleeve in the sleeve sealing valve can be replaced and the flow rate of the sleeve sealing valve can be adjusted.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined Figure 1 - Figure 5 This invention describes the adjusting device for the sleeve sealing valve.

[0027] In one embodiment, the sleeve sealing valve regulating device includes a valve plate 100, with a valve cover 200 installed on the top of the valve plate 100; a replacement mechanism 300, which can replace the sleeve inside the sleeve sealing valve and regulate the flow rate of the sleeve sealing valve, is disposed on the inner wall of the valve plate 100; wherein, the replacement mechanism 300 includes a sleeve body 310 that is snapped into the inner wall of the valve plate 100, and two locking blocks 320 are slidably connected to both sides of the inner wall of the valve plate 100. Two compression springs 330 are disposed between one side of the locking block 320 and the valve plate 100, and the other side of the locking block 320 penetrates the valve plate 100 and is embedded in the inner wall of the sleeve body 310.

[0028] It should be noted that the sleeve sealing valve with model number "LN8300" consists of a valve body, sleeve, valve core, valve cover 200, and electric and pneumatic components;

[0029] The sleeve has multiple throttling windows. The shape of the windows determines the flow characteristics of the control valve, and the size of the window area affects the flow coefficient of the control valve.

[0030] When adjusting the sleeve sealing valve, the replacement mechanism 300 can quickly install and remove the sleeve body 310 by cooperating with the compression spring 330 through two locking blocks 320. The connecting ring 350 on the sleeve body 310 is embedded in the valve plate 100 and cooperates with the sealing ring 360 to seal the sleeve body 310. The retaining ring 370 cooperates with the sealing sleeve 380 to seal the sleeve body 310. The fixing bolt 390 installs the valve cover 200 on the sleeve body 310, which allows the sleeve body 310 to be replaced without affecting the normal use of the sleeve sealing valve.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the replacement mechanism 300 also includes a groove 340 formed at the top of the locking block 320, the top of the locking block 320 extending through to the outer wall of the valve plate 100, and the two ends of the compression spring 330 extending through to the inner walls of the locking block 320 and the valve plate 100 respectively.

[0032] In this embodiment, the locking blocks 320 on both sides of the inner wall of the valve plate 100 can move towards the inner wall of the valve plate 100 through the grooves 340 and squeeze the two compression springs 330, thereby releasing the restriction of the locking blocks 320 on the sleeve body 310. The sleeve body 310 can then be removed from the sleeve sealing valve for replacement, and the flow rate of the sleeve sealing valve can be adjusted. When replacing the new sleeve body 310, the locking blocks 320 are placed inside the valve plate 100. The two locking blocks 320 are supported by the energy generated after being compressed by the two compression springs 330. The locking blocks 320 are embedded in the sleeve body 310 for fixation, which facilitates the disassembly and replacement of the sleeve body 310. The flow rate of the sleeve sealing valve can be adjusted by replacing the sleeve body 310 with different throttling windows.

[0033] like Figure 2 and Figure 5 As shown, a connecting ring 350 is fixedly connected to the bottom end of the sleeve body 310. The bottom end of the connecting ring 350 is embedded in the inner wall of the valve plate 100. A sealing ring 360 is fixedly connected to the inner wall of the valve plate 100. The inner wall of the sealing ring 360 is in contact with the connecting ring 350. A retaining ring 370 is installed at the bottom end of the sleeve body 310. A sealing sleeve 380 is installed in the middle of the inner wall of the valve plate 100. The retaining ring 370 is in contact with the sealing sleeve 380. The diameter of the retaining ring 370 and the sealing sleeve 380 is smaller than the diameter of the connecting ring 350. Several evenly arranged fixing bolts 390 are installed at the top end of the valve cover 200. One end of the fixing bolt 390 passes through the valve cover 200 and is threadedly connected to the valve plate 100.

[0034] In this embodiment, when the sleeve body 310 is replaced and installed inside the valve plate 100, the sleeve body 310 drives the connecting ring 350 to embed into the top of the valve plate 100. The sealing ring 360 inside the valve plate 100 fits against the connecting ring 350, which can seal the connection between the sleeve body 310 and the valve plate 100. As the sleeve body 310 is installed, the retaining ring 370 is embedded in the middle of the inner wall of the valve plate 100, and the inner wall of the sealing sleeve 380 fits against the retaining ring 370, which seals the sleeve body 310. The valve cover 200 can be installed on the valve plate 100 by multiple fixing bolts 390, which can fix the sleeve body 310 and seal the sleeve body 310, making it convenient to replace the sleeve body 310.

[0035] Working principle: By engaging the fixing bolts 390 on the valve cover 200 with the valve plate 100, the valve cover 200 can be removed, releasing the restriction on the sleeve body 310. Manually pulling the tops of the two locking blocks 320 with the grooves 340 allows one side of the locking blocks 320 to move from inside the sleeve body 310 to inside the valve plate 100, releasing the restriction on the sleeve body 310. The sleeve body 310 can then be removed and replaced. The new sleeve body 310 is placed inside the valve plate 100, and one side of the two locking blocks 320 is embedded in the sleeve body 310, allowing the sleeve body 310 to be installed. The sleeve body 310 drives the connecting ring 350 to embed into the valve plate 100 and fit against the sealing ring 360. The sleeve body 310 drives the retaining ring 370 to insert into the inner wall of the sleeve body 310 and fit against the sealing sleeve 380 for sealing. The valve cover 200 is installed on the valve plate 100 by the fixing bolts 390.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
