Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, specifically to a high-pressure resistant protective cover for a flow meter. Background Technology

[0002] A flow meter is a crucial measuring device commonly used to measure the flow rate of fluids in pipelines. It can also monitor changes in fluid flow rate during production in real time, aiding in production adjustments. Flow meters are typically equipped with a protective cover to protect the meter from external damage and extend its service life.

[0003] For example, Chinese Patent Publication No. CN202120456010.1 discloses a flow meter with a protective cover, relating to the field of flow meter technology. The casing has connecting flanges at both ends, a flow sensor in the middle, and the sensor's detection head extending into the casing. Several inner shock-absorbing sleeves are installed on the outer wall of the casing, and several elastic connecting columns are evenly installed on the outer walls of these sleeves. An outer protective cover is installed on the outer walls of these elastic connecting columns. An inner shock-absorbing cotton body is connected to the inner wall of the outer connecting sleeve, and an inner fixing sleeve is connected to the inner wall of the inner shock-absorbing cotton body. Several energy-absorbing columns are evenly connected to the outer wall of the inner cover, and an outer cover is connected to the outer walls of these energy-absorbing columns. This invention provides rapid protection, improves stability, facilitates quick use, and is easy to operate. Its simple structure allows for rapid operation, saves time, and improves overall efficiency.

[0004] The aforementioned protective cover also has the following problems when in use: the cover body is not easy to disassemble, which means that when the flow meter body needs to be inspected and maintained, the entire protective cover must be removed, which is cumbersome and requires subsequent installation. The overall disassembly and assembly is inconvenient and time-consuming, affecting the maintenance efficiency of the flow meter. Utility Model Content

[0005] To address this issue, this utility model provides a high-pressure resistant protective cover for a flow meter, solving the problem in the prior art where the protective cover is inconvenient to disassemble, requiring the entire protective cover to be removed before the flow meter can be inspected and maintained. This operation is cumbersome, and subsequent installation is also required, making the overall disassembly and assembly inconvenient and time-consuming, thus affecting the maintenance efficiency of the flow meter.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-pressure resistant protective cover for a flow meter includes a pipe body, both ends of which are connected to a measuring pipe. A flow meter is fitted inside the pipe body. A first protective cover is fixedly connected to the outer wall of the pipe body and is fitted onto the outside of the flow meter. A second protective cover is movably fitted onto the top of the first protective cover via an installation component. The second protective cover is also movably fitted onto the outside of the flow meter. The installation component uses a limiting moving component to prevent the first and second protective covers from detaching.

[0008] Furthermore, the top of the first protective cover is flush with the lower end of the flow meter body, and the second protective cover, which is movably installed on the top of the first protective cover, is a transparent cover. The height of the second protective cover is greater than the overall height of the flow meter, so that the flow meter can be exposed when the second protective cover moves upward, which facilitates the subsequent inspection and maintenance of the flow meter.

[0009] Furthermore, the outer diameter of the first protective cover is larger than that of the second protective cover, and the inner diameter of the first protective cover is smaller than that of the second protective cover. Both the inner circles of the first and second protective covers have gaps with the flow meter body to ensure that the flow meter will not be affected when the second protective cover is twisted later.

[0010] Furthermore, the mounting assembly includes an arc-shaped side plate fixedly connected to the lower end of the second protective cover, and the outer wall of the arc-shaped side plate is provided with mounting threads. The mounting threads are threadedly connected to the threaded mounting groove reserved inside the first protective cover. In this way, twisting the second protective cover causes the arc-shaped side plate fixedly connected to the lower end of the second protective cover to rotate inside the threaded mounting groove, thereby moving the position up and down. This facilitates the movement of the upper and lower positions of the second protective cover fixedly connected to the arc-shaped side plate, making it convenient for the flow meter to be inspected, maintained, and closed.

[0011] Furthermore, the arc-shaped side plate is provided in two pieces, and the two arc-shaped side plates are symmetrically arranged with reference to the central axis of the second protective cover as the axis of symmetry. An area for maintenance of the flow meter is left between the two arc-shaped side plates. By twisting the second protective cover, the arc-shaped side plate fixedly connected to the lower end of the second protective cover can be rotated inside the threaded mounting groove to achieve up and down movement of the position. The maintenance operation of the flow meter can be achieved through the two arc-shaped side plates.

[0012] The height of the arc-shaped side plate is greater than the height of the second protective cover, which allows the second protective cover to move upwards to fully expose the flow meter.

[0013] Furthermore, the threaded mounting groove is annular, and the threaded mounting groove and the arc-shaped side plate are connected to prevent detachment through a limiting moving component, so as to avoid the detachment of the first protective cover and the second protective cover from affecting the subsequent protection of the flow meter.

[0014] Furthermore, the limited moving component includes an annular channel preset inside the threaded mounting groove, and an annular block is rotatably connected inside the annular channel. The limiting blocks fixedly connected to both sides of the annular block slide in match with the limiting vertical groove reserved inside the arc-shaped side plate. In this way, the annular block that can rotate inside the annular channel and the limiting blocks fixedly connected to the annular block will not affect the rotation of the arc-shaped side plate inside the threaded mounting groove.

[0015] Furthermore, the top and bottom of the limiting vertical groove are both closed, and the inner wall of the limiting vertical groove is attached to the outer wall of the limiting block to achieve a sliding connection between the upper and lower parts. In addition, the limiting vertical groove is not connected to the threaded mounting groove, thus ensuring that the movement distance between the limiting vertical groove and the limiting block is limited, and ensuring the anti-detachment installation of the first protective cover and the second protective cover.

[0016] This utility model has the following advantages:

[0017] During use, the twisting of the second protective cover causes the arc-shaped side plate fixedly connected to the lower end of the second protective cover to rotate inside the threaded mounting groove, thereby facilitating the vertical movement of the second protective cover, which is fixedly connected to the arc-shaped side plate. This makes it convenient to carry out maintenance and sealing operations on the flow meter. At the same time, the movement of the arc-shaped side plate is restricted by the limiting block, which ensures the anti-detachment installation of the first and second protective covers and prevents the first and second protective covers from falling off.

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model provides, for example Figure 1-4 The high-pressure resistant protective cover for a flow meter shown includes a pipe body 1, with both ends of the pipe body 1 connected to a measuring pipe. A flow meter 2 is fitted inside the pipe body 1. A protective cover 3 is fixedly connected to the outer wall of the pipe body 1 and is fitted onto the outside of the flow meter 2. A second protective cover 4 is movably fitted onto the top of the first protective cover 3 via an installation component 5. The second protective cover 4 is also movably fitted onto the outside of the flow meter 2. The installation component 5 uses a limiting movement component 6 to prevent the first protective cover 3 and the second protective cover 4 from detaching.

[0027] During use, the twisting of the second protective cover 4 causes the arc-shaped side plate 501, which is fixedly connected to the lower end of the second protective cover 4, to rotate inside the threaded mounting groove 503, thereby moving the position up and down. This facilitates the movement of the second protective cover 4, which is fixedly connected to the arc-shaped side plate 501, and makes it convenient to carry out maintenance and sealing operations on the flow meter 2. At the same time, the movement of the arc-shaped side plate 501 is restricted by the limiting block 603, which ensures the anti-detachment installation of the first protective cover 3 and the second protective cover 4, and prevents the first protective cover 3 and the second protective cover 4 from falling off.

[0028] The top of the protective cover 3 is flush with the lower end of the flow meter 2. The protective cover 4, which is movably installed on the top of the protective cover 3, is a transparent cover. The height of the protective cover 4 is greater than the overall height of the flow meter 2. The outer diameter of the protective cover 3 is greater than the outer diameter of the protective cover 4, and the inner diameter of the protective cover 3 is smaller than the inner diameter of the protective cover 4. There are gaps between the inner circles of both the protective cover 3 and the protective cover 4 and the flow meter 2. This allows the flow meter 2 to be exposed when the protective cover 4 moves upward, facilitating subsequent inspection and maintenance of the flow meter 2. It also ensures that twisting the protective cover 4 will not affect the flow meter 2.

[0029] The mounting assembly 5 includes an arc-shaped side plate 501 fixedly connected to the lower end of the protective cover 2 4. The outer wall of the arc-shaped side plate 501 is provided with a mounting thread 502, and the mounting thread 502 is threadedly connected to the threaded mounting groove 503 reserved inside the protective cover 1 3. There are two arc-shaped side plates 501, and the two arc-shaped side plates 501 are symmetrically arranged with reference to the central axis of the protective cover 2 4 as the axis of symmetry. An area for maintenance of the flow meter 2 is left between the two arc-shaped side plates 501.

[0030] This twisting of the protective cover 2 4 causes the arc-shaped side plate 501 fixedly connected to the lower end of the protective cover 2 4 to rotate inside the threaded mounting groove 503, thereby moving the position up and down. This facilitates the up and down movement of the protective cover 2 4, which is fixedly connected to the arc-shaped side plate 501. The flow meter 2 can be inspected and maintained through the two arc-shaped side plates 501, making it convenient to carry out inspection, maintenance and sealing operations on the flow meter 2. The height of the arc-shaped side plate 501 is 1.5 times the height of the protective cover 2 4, which makes it convenient for the protective cover 2 4 to move upward and fully expose the flow meter 2.

[0031] The threaded mounting groove 503 is annular, and the threaded mounting groove 503 and the arc-shaped side plate 501 are connected to each other to prevent detachment through the limiting moving component 6. The limiting moving component 6 includes an annular channel 601 pre-set inside the threaded mounting groove 503, and an annular block 602 is rotatably connected inside the annular channel 601. The limiting blocks 603 fixedly connected on both sides of the annular block 602 are in sliding match with the limiting vertical groove 604 reserved inside the arc-shaped side plate 501. The top and bottom of the limiting vertical groove 604 are closed, and the inner wall of the limiting vertical groove 604 is attached to the outer wall of the limiting block 603 to achieve a sliding connection. The limiting vertical groove 604 is not connected to the threaded mounting groove 503.

[0032] In this way, the rotatable annular block 602 inside the annular channel 601 and the limiting block 603 fixedly connected to the annular block 602 will not affect the rotation of the arc-shaped side plate 501 inside the threaded mounting groove 503. At the same time, it ensures that the movement distance between the reserved limiting vertical groove 604 inside the arc-shaped side plate 501 and the limiting block 603 is limited, thus ensuring the anti-detachment installation of the protective cover 1 3 and the protective cover 2 4.

[0033] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
