Description

Technical Field

[0001] The invention relates to the technical field of transmitters, in particular to a split-type flange-connected transmitter. Background Art

[0002] A transmitter is a converter that converts the output signal of a sensor into a signal that can be recognized by a controller (or converts the non-electrical quantity input by the sensor into an electrical signal and amplifies it for remote measurement and control). The sensor and the transmitter together constitute the monitoring signal source for automatic control. Different physical quantities require different sensors and corresponding transmitters.

[0003] The use scenarios of transmitters are also diverse. The transmitter of the technical solution of this application is mainly used to transmit signals in some complex situations such as underwater, industrial oil, and liquid level in large ship cabins. The environment and problems faced by transmitters used in liquid environments are also relatively complex. Existing transmitters, especially transmitters used in liquid environments, usually connect the underwater sensing part and the power supply and output part above water through a dedicated cable. Generally, the cable and the sensor part are inseparable. When replacing and maintaining the sensor part, the cable part must be removed together. When the cable is too long, the value of the cable itself will exceed the transmitter itself. If the transmitter fails and is repaired, it will cause very high maintenance costs.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a split flange connection transmitter to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A split flange connection transmitter comprises a lower flange and an upper flange, wherein the lower flange is detachably mounted on the bottom of the upper flange.

[0008] The inner edge and the outer edge of the top of the lower flange are both provided with annular grooves, and the first sealing ring and the second sealing ring are respectively embedded in the inner cavities of the two annular grooves. A polymer plug is installed through the edge of the top of the lower flange, and a polymer plug air guide tube is inserted into the inner cavity of the polymer plug. A high-temperature resistant and waterproof connector is installed in the middle of the top of the lower flange.

[0009] A convex structure is arranged at the top of the upper flange, a matching metal gasket and a fluororubber rectangular gasket are arranged at the bottom of the inner cavity of the convex structure, and a clamping screw is inserted at the top of the inner cavity of the convex structure.

[0010] Optionally, the polymer plug air guide tube is a breathable and water-tight tube structure, and the polymer plug air guide tube connects the inner cavities of the lower flange and the upper flange.

[0011] Optionally, the number of the matching metal washers and the fluororubber rectangular washers is at least two, and the matching metal washers and the fluororubber rectangular washers are installed in an intermittent distribution.

[0012] Optionally, the clamping screw is a hollow rubber screw structure, a special cable is inserted into the inner cavity of the clamping screw, and the bottom of the special cable passes through the clamping screw, the matching metal washer and the center hole of the fluororubber rectangular washer in sequence and extends into the inner cavity of the upper flange. The inner diameter of the clamping screw is smaller than the outer diameter of the special cable.

[0013] Optionally, a high-temperature resistant silicone wire is installed through the inner cavity of the high-temperature resistant waterproof plug-in, and the upper end of the high-temperature resistant silicone wire is electrically connected to the bottom end of the dedicated cable.

[0014] Optionally, sealant is poured on the top of the upper flange inner cavity and the top of the lower flange, and the connection position of the high-temperature resistant silicone wire and the special cable, the installation position of the high-temperature resistant waterproof plug-in and the polymer plug air guide tube and the lower flange are all immersed in the sealant.

[0015] Optionally, threaded holes are provided at the edges of the upper flange and the lower flange, and M16 bolts are threadedly installed in the inner cavities of the threaded holes, and an O-ring is mounted on the outer ring of the M16 bolts.

[0016] Optionally, a sealing ring is mounted on the protruding position on the top of the lower flange, and the outer wall of the sealing ring is fixedly mounted on the inner wall of the upper flange.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all the advantages described below at the same time:

[0018] In practical applications of the present invention, users can significantly reduce procurement costs by purchasing only two transmitter sensor parts and a set of cables. Compared with a full set of transmitter systems, this option can significantly save initial investment and provide the convenience of rapid replacement when a sensor fails, thereby ensuring the continuous operation of the system and avoiding production losses caused by equipment downtime. In addition, this solution simplifies the maintenance process. Users only need to return the damaged sensor part alone for repair without disassembling the entire transmitter, thereby reducing maintenance time and costs and improving maintenance efficiency. At the same time, this configuration method allows users to flexibly adjust and expand the system according to actual needs, avoiding unnecessary waste of funds, making system maintenance and upgrades more efficient, and meeting the dual requirements of economy and ease of operation. Through this preparatory plan, users can not only obtain significant cost benefits in the procurement and maintenance stages, but also ensure the efficiency and stability of equipment operation, thereby improving overall economic benefits.

DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figure 1-4 As shown, in this embodiment, a split flange connection transmitter is provided, which is mainly composed of a lower flange 1 and an upper flange 5, and the upper flange 5 and the lower flange 1 are detachably butt-connected.

[0031] like Figure 1 and Figure 3 As shown, annular grooves are provided at the inner and outer edges of the top of the lower flange 1, and the first sealing ring 2 and the second sealing ring 3 are embedded in the annular grooves of the inner and outer edges, respectively. A polymer plug is installed through the side of the top of the lower flange 1, and a polymer plug air guide 12 is inserted in the inner cavity of the polymer plug, and a high-temperature resistant waterproof plug 6 is installed in the middle of the top of the lower flange 1. The polymer plug air guide 12 is a breathable and water-tight pipe structure. After installation, the lower flange 1 can be connected with the inner cavity of the upper flange 5, that is, the air circulation between the lower flange 1 and the upper flange 5 can be realized.

[0032] like Figure 1 and Figure 2 As shown, a convex structure is provided in the middle of the top of the upper flange 5, and a matching metal gasket 9 and a fluororubber rectangular gasket 8 are provided in the inner cavity of the convex structure, and a clamping screw 10 is inserted at the top of the inner cavity of the convex structure. The clamping screw 10 is a hollow screw structure made of rubber. When the clamping screw 10 is continuously screwed downward along the inner cavity of the convex structure, the bottom of the clamping screw 10 will continuously squeeze the matching metal gasket 9 and the fluororubber rectangular gasket 8, so that the matching metal gasket 9 squeezes the fluororubber rectangular gasket 8 to deform, and when the fluororubber rectangular gasket 8 is deformed, it can continuously fit with the inside of the convex structure to achieve sealing.

[0033] Among them, Figure 1 As shown, a threaded structure is provided on the inner wall of the convex structure, and the clamping screw 10 is threadedly connected to the upper flange 5. The clamping screw 10 is installed by threaded installation, mainly for the convenience of disassembly and assembly. At the same time, with the design of the clamping screw 10 made of rubber material, the clamping screw 10 will be deformed under the influence of the interaction force during the process of being screwed in, so as to better fit the inside of the convex structure and achieve a sealing effect.

[0034] Among them, the number of the matching metal washers 9 and the fluororubber rectangular washers 8 is at least two, and the matching metal washers 9 and the fluororubber rectangular washers 8 are alternately distributed. The staggered distribution of the matching metal washers 8 and the fluororubber rectangular washers 9 is, on the one hand, to prevent the fluororubber rectangular washers 8 from being affected by high temperature during use and sticking to each other to affect the sealing performance, and on the other hand, to ensure that the extrusion force of each layer of the fluororubber rectangular washers is more evenly distributed, that is, the fluororubber rectangular washers 8 can be deformed more evenly.

[0035] Among them, Figure 1 and Figure 2 As shown, the clamping screw 10 has a hollow screw structure, and a special cable 11 is installed through the inner cavity of the clamping screw 10, and the bottom of the special cable 11 passes through the convex structure and extends into the inner cavity of the upper flange 5. The bottom of the special cable 11 extends into the inner cavity of the upper flange 5, mainly to facilitate docking installation in the initial state, so that the line docking installation has more space for operability. The outer diameter of the special cable 11 is larger than the inner diameter of the clamping screw 10, and the bottom of the special cable passes through the center holes of each matching metal gasket 9 and the fluororubber rectangular gasket 8 in turn, so that when the clamping screw 10 and the fluororubber rectangular gasket 8 are squeezed and deformed, they can better fit the outer wall of the special cable 11, and achieve the sealing between the clamping screw 10, the matching metal gasket 9 and the fluororubber rectangular gasket 8 and the special cable 11.

[0036] Among them, Figure 1 and Figure 2 As shown, a high temperature resistant silicone wire 7 is electrically connected to the top of the high temperature resistant waterproof plug 6, and the top of the high temperature resistant silicone wire 7 is electrically connected to the bottom of the special cable 11. The main function of the high temperature resistant waterproof plug 6 is to ensure the sealing and waterproofness of the line docking installation, and the main purpose of the high temperature silicone wire 7 being electrically connected to the special cable 11 is to transmit various signals.

[0037] Among them, Figure 1 and Figure 2As shown, at the top of the inner wall of the upper flange 5, the sealant is fully injected to ensure the absolute sealing of the internal joint. The joint position of the high-temperature resistant silicone cable 7 and the special cable 11 is completely immersed and wrapped by the sealant. This treatment not only effectively ensures the sealing of the joint, but also provides excellent waterproof performance. The main purpose of using sealant is to prevent the infiltration of external liquids or gases, thereby protecting the cable joint from environmental influences and ensuring its stability and reliability under various working conditions. In addition, the sealant also plays a role in reinforcing the joint. After curing, it forms a solid protective layer, which can effectively prevent the joint position from falling off or separating due to pulling or impact during the disassembly and reassembly of the equipment. This reinforcement effect not only enhances the mechanical strength of the joint, but also reduces the maintenance frequency and cost caused by joint problems, thereby improving the durability and maintenance convenience of the overall equipment. Through this design, users can enjoy higher equipment reliability and stability in long-term use, while avoiding frequent maintenance and repair work.

[0038] Among them, Figure 1 As shown, the upper flange 5 and the lower flange 1 are provided with threaded hole structures at the edges of the tops, and the upper flange 5 and the lower flange 1 are fixed by 6 M16 bolts 13, and the outer rings of the M16 bolts 13 are provided with double-sided tooth anti-loosening washers 14. The upper flange 5 and the lower flange 1 are fixed by M16 bolts 13, mainly to facilitate the separation of the upper flange 5 and the lower flange 1, and the double-sided tooth anti-loosening washers 14 are mainly designed to increase the stability of the M16 bolts 13 after installation, that is, to avoid the problem of the M16 bolts 13 being loosened and falling off due to self-rotation caused by vibration and impact during use.

[0039] Among them, Figure 1 As shown, the bottom of the high temperature resistant waterproof plug-in 6 is designed with a special plug-in groove, and the inner cavity of the groove is equipped with an O-ring, which is mounted on the outer ring of the tightening nut to ensure the tight sealing of the plug-in position. This design can effectively prevent the external environment (such as moisture or dust) from invading the interior of the plug-in, thereby ensuring its long-term stable working performance. On the inner wall of the plug-in groove, a tightening nut for docking with the lower flange is fixedly installed. The nut is threadedly connected to make the connection between the plug-in and the flange more stable, preventing loosening or falling off due to vibration or external force.

[0040] In addition, the high temperature resistant waterproof plug-in 6 adopts a detachable threaded installation method. This design is not only convenient for subsequent maintenance and repair, but also significantly improves the operation and maintenance efficiency of the equipment. When the transmitter fails or needs to be replaced, the user only needs to remove the high temperature resistant waterproof plug-in 6 for replacement, without having to replace the entire transmitter system. This reduces maintenance costs on the one hand, and avoids the high cost of comprehensive equipment replacement on the other. Through this modular design, users can flexibly respond to equipment failures, reduce maintenance difficulties, and improve the reliability and economy of the overall system.

[0041] Among them, Figure 1 As shown, sealant is also poured on the top of the lower flange 1, and the docking installation position of the high temperature resistant waterproof plug 6 and the lower flange and the plugging position of the polymer plug air duct 12 and the lower flange 1 are all wrapped and covered by the sealant. The sealant in this technical solution is used to improve the sealing of the installation position of the high temperature resistant waterproof plug 6 and the polymer plug air duct 12, and at the same time, it can also increase the firmness of the installation of the high temperature resistant waterproof plug 6 and the polymer plug air duct 12, so that they will not fall off or loosen easily.

[0042] Among them, Figure 1 As shown, a sealing ring 4 is installed at the bottom of the inner wall of the upper flange 5, and the sealing ring 4 is sleeved on the outer wall of the protruding end of the top of the lower flange 1 after the upper flange 5 and the lower flange 1 are installed, thereby achieving sealing between the upper flange 5 and the lower flange 1 at one time.

[0043] In this embodiment, based on the transmitter and connector principles, before the lower flange 1 and the upper flange 5 are installed, the dedicated cable is inserted into the upper flange 5, and after extending to a certain length inside the upper flange 5, the compression screw 10 is rotated to fix the dedicated cable and achieve upper end sealing;

[0044] Then install the polymer plug air guide tube 12 and the high temperature resistant waterproof plug 6 on the lower flange 1, and then connect and fix the upper end of the high temperature resistant silicone cable 7 with the bottom end of the special cable 11, and finally pour the sealant on the inner cavity of the upper flange 5 and the top of the lower flange 1 respectively;

[0045] Finally, the upper flange 5 and the lower flange 1 can be connected, and the multiple threaded hole structures can be aligned, and the multiple M16 bolts 13 can be screwed in to complete the assembly.

[0046] After the split flange connection transmitter is assembled, it must be completely isolated from the external medium (such as water) and ensure the safe transmission of the signal in the inner cavity. Therefore, the sealing of the split flange connection transmitter itself and the sealing of the transmitter's dedicated cable are the difficulties of this split flange connection transmitter.

[0047] In order to ensure the reliable sealing of the liquid level sealing connector, four O-ring seals are used in the structure. After many tests and calculations, it has been determined that its tolerance meets the sealing requirements. In addition to the conventional sealing ring seal, the dedicated cable of the transmitter also uses glue sealing to ensure its sealing reliability.

[0048] The use of this sealing form ensures that even if the cable sheath is slightly damaged during use, the seal in the air guide cavity will not be damaged, thereby improving the reliability of the transmitter product.

[0049] The present invention is not limited to the above-mentioned embodiments. Anyone should be aware that any structural changes made under the enlightenment of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the protection scope of the present invention. The technology, shape, and structural parts not described in detail in the present invention are all well-known technologies.
