Description

Technical Field

[0001] The utility model relates to the technical field of instrument installation devices, in particular to an installation and maintenance kit for plug-in instruments. Background Art

[0002] A meter is typically a measuring instrument that can be inserted directly into a pipe, vessel, or other process equipment. These meters are designed to come into direct contact with fluids or gases to monitor various parameters, such as pressure, temperature, and flow. Currently, there are two main installation methods for insertion meters: First, the meter is inserted directly into the pipe or tank without a barrier between it and the measured medium; second, a barrier is added between the meter and the measured medium, which can be disconnected after the meter is withdrawn a certain distance from the pipe or tank.

[0003] For example, patent document CN111982219A discloses an insertion-type ultrasonic flowmeter, comprising a pipe, a flow reflection mechanism, an ultrasonic sensor, and an ultrasonic reflector. The upper outer wall of the pipe is fixedly connected to a first flange via a support seat. The flow reflection mechanism is located above the pipe, and the lower end of the flow reflection mechanism is fixedly connected to a second flange via a support rod. The first flange is fixedly connected to the second flange via a plurality of first bolts. Circular holes are provided in the middle of the front and rear sides of the pipe. The ultrasonic sensor and ultrasonic reflector are located inside the pipe, corresponding to the positions of the two circular holes. The main installation method of this scheme is to install a threaded joint or flange interface on the wall of the pipe or storage tank, insert the insertion-type instrument with a matching threaded joint or flange into the measured medium, and then tighten the threaded joint or flange bolts to complete the instrument installation. This installation method facilitates the installation and fixing of the flow reflection mechanism to the pipe, and facilitates the insertion and installation of the ultrasonic sensor and ultrasonic reflector into the pipe and their corresponding positions. It also facilitates the adjustment of the distance between the ultrasonic sensor and ultrasonic reflector, making it easier for people to use.

[0004] In order to facilitate the online withdrawal and maintenance of the instrument, the instruments in the prior art generally have a ball valve or other isolating device on the sleeve of the connecting pipe. The instrument can be inserted into the measured medium with the isolating device open, and the isolating device can be closed after the instrument is pulled out a certain distance. However, when the instrument needs to be repaired or installed online, it is necessary to loosen the sealing assembly and pull the instrument out a certain distance. At this time, the measured medium will leak directly from the pipeline. In a high-pressure environment, the sudden release of the measured medium may cause severe physical impact and cause harm to nearby people. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] In order to solve the technical problem that when the instrument needs to be repaired or installed online, it is necessary to loosen the sealing component and pull the instrument out a certain distance, at which time the measured medium will leak, making the existing instrument unsuitable for the measured medium with slightly higher pressure or dangerous, the utility model provides an installation and maintenance kit for plug-in instruments.

It can effectively prevent the sudden release and leakage of pipelines or storage tanks under high-pressure environments, which not only improves the safety and reliability of the system, but also increases the convenience of maintenance and operation.

[0029] See also Figure 1 , Figure 1This is a schematic diagram of the overall cross-sectional structure of an installation and maintenance kit for an insertable instrument in an embodiment of the present invention.

[0030] In this device, the detection part is connected to the fixed part through the connecting part. The detection end of the detection part can pass through the sealing end of the partition device 2 and the mounting base 1 in sequence and extend into the equipment component 6. The position of the detection part relative to the fixed part can be adjusted through the connecting part, and then the installation depth of the detection end can be adjusted to ensure the best installation and use effect; the connecting part can also realize the complete extraction of the detection part from the measured medium. The partition device 2 can provide a reliable closing function between the instrument and the pipeline. The detection end of the detection part can be moved out of the equipment component 6 through the completely sealed connecting part, and then the partition device 2 can be used for partition sealing, and then the detection part can be removed. This can prevent the medium from suddenly releasing and leaking when the instrument is disassembled, thereby realizing online disassembly and maintenance of the instrument.

[0031] It should be noted that in this embodiment, the mounting base 1 is connected to an equipment component 6, which includes a device capable of containing a medium, such as a pipe or a storage tank. The mounting base 1 is made of the same material as the pipe or storage tank wall and is connected to the partition device 2 using an interface such as threads, flanges, or a flange.

By adjusting the tie rod nuts 56 on both sides of the first tie rod fixing ear 53, the first tie rod fixing ear 53 can be driven to move on the threaded tie rod 55, and the instrument fixing seat 51 and the instrument body 3 can be driven to move through the first tie rod fixing ear 53, so that the position of the instrument body 3 can be adjusted. Not only can the insertion depth of the detection probe 31 of the instrument body 3 be adjusted, but the instrument body 3 can also be driven to move out of the equipment component 6, so as to close the partition device 2 for online maintenance or installation of the instrument.

[0042] It should be noted that, in other possible embodiments, the connection method between the adjustable pipe section 4 and the pipe section connector 5 is not limited thereto, and the adjustable pipe section 4 can also be connected to the pipe section connector 5 using a mortise and tenon structure or the like.

[0043] The above embodiments are merely multiple possible implementations of the embodiments of the present application, and the embodiments of the present application are not limited thereto.

[0046] (2) Connect the isolation device 2 to the mounting base 1. Use flange connection, threaded connection, and copy forest connection to match the installation. The isolation device 2 uses a valve with a complete flow channel, such as a ball valve or a gate valve.

[0047] (3) Connect the pipe section connector 5 to the partition device 2. The pipe section connector 5 uses a matching flange, and the outer edge of the flange has a hole for installing the threaded pull rod 55.

[0048] (4) Connect the adjustable pipe section 4 to the pipe section connector 5. The adjustable pipe section 4 is pre-connected to form a whole using a matching flange.

The end of the pipe section is installed and pressed on the instrument fixing seat 51 and the partition connecting seat 52 using a clamping ring 41 and matching bolts. The instrument fixing seat 51 and the partition connecting seat 52 need to have corresponding bolt mounting holes. The adjustable pipe section 4 has the function of extending and compressing the length.

[0049] (5) The length of the pipe section can be adjusted by the threaded tie rod 55 and the tie rod nut 56 to adapt to different instrument length requirements. When the detection probe 31 of the instrument body 3 needs to be pulled out for maintenance, the length of the adjustable pipe section 4 is extended, and then the isolation device 2 is turned off. Finally, the connecting flange of the instrument body 3 is disassembled and the instrument body 3 is completely removed for maintenance.

[0050] (6) During installation, after the instrument is installed, open the partition device 2, adjust the length of the threaded pull rod 55, and insert the instrument probe into the medium to be measured.

The detection end of the detection part can pass through the sealing end of the partition device 2 and the mounting base 1 in sequence and extend into the equipment component 6. The position of the detection part relative to the fixing part can be adjusted through the connecting part, and then the installation depth of the detection end can be adjusted to ensure the best installation and use effect; the connecting part can also realize the complete extraction of the detection part from the measured medium, and the partition device 2 can provide a reliable closing function between the instrument and the pipeline. The detection end of the detection part can be moved out of the equipment component 6 through the completely sealed connecting part, and then the partition device 2 is used for partition sealing, and then the detection part is removed, which can prevent the medium from suddenly releasing and leaking when the instrument is disassembled, thereby realizing online disassembly and maintenance of the instrument. This solution can remove the detection probe 31 of the instrument body 3 from the equipment component 6 through the completely sealed connection part, and then use the partition device 2 to perform partition sealing. The instrument can be disassembled after the partition sealing. This sealing method is convenient and reliable, and can effectively prevent the sudden release and leakage of the measured medium in the pipeline or storage tank under high-pressure environment. It not only improves the safety and reliability of the system, but also increases the convenience of maintenance and operation.
