Description

Technical Field

[0001] The utility model relates to the technical field of temperature measurement, in particular to a temperature measurement component installation structure. Background Art

[0002] During the fluid transportation process, the fluid temperature needs to be measured. In order to prevent the thermometer from being corroded by the fluid and ensure the sealing of the fluid transportation pipeline, the usual practice is to insert the thermometer into the thermometer sleeve and extend the thermometer sleeve into the fluid transportation pipeline so that the measured fluid medium does not directly contact the thermometer sleeve. The thermometer indirectly measures the actual temperature of the fluid by sensing the temperature at the end of the thermometer sleeve.

[0003] When the fluid flows through the thermometer sleeve, the blocking effect of the thermometer sleeve on the fluid will cause the momentum of the fluid to change, and a wake will be generated at the rear of the sleeve, and a vortex will be formed in the wake. The vortex will fall off alternately along both sides of the sleeve (Karman vortex street phenomenon). This alternating vortex directly acts on the thermometer sleeve, causing the thermometer sleeve to resonate violently along its radial direction. Over time, the thermometer sleeve will produce fatigue fracture, and the thermometer inserted in the thermometer sleeve will be damaged, affecting the temperature measurement, and even causing an accident.

[0004] Therefore, it is urgent to invent a temperature measurement component installation structure to solve the above problems. Utility Model Content

When the sleeve part is extended into the fluid to be measured, the temperature measuring component can measure the temperature of the fluid to be measured. By providing a guide groove on the outer peripheral wall of the sleeve part, the guide groove is bent toward the direction close to the installation part while extending radially along the sleeve part, so that the fluid to be measured is moved away from the opening of the installation part in the guide groove. The fluid to be measured enters the guide groove through the opening and flows out from the opening in the guide groove close to the mounting portion. When the fluid to be measured flows in the guide groove, the force exerted by the fluid to be measured on the sleeve portion is split into radial force and axial force.

[0043] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0046] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] In order to ensure the safety of fluid transportation, the temperature of the fluid needs to be measured. Specifically, the thermometer is inserted into the thermometer sleeve, and the thermometer sleeve is extended into the fluid transportation pipeline, so that the measured fluid medium does not directly contact the thermometer sleeve. The thermometer indirectly measures the actual temperature of the fluid by sensing the temperature at the end of the thermometer sleeve.

[0048] When the fluid flows through the thermometer sleeve, the blocking effect of the thermometer sleeve on the fluid will cause the momentum of the fluid to change, and a wake will be generated at the rear of the sleeve, and a vortex will be formed in the wake. The vortex will fall off alternately along both sides of the sleeve (Karman vortex street phenomenon). This alternating vortex directly acts on the thermometer sleeve, causing the thermometer sleeve to resonate violently along its radial direction. Over time, the thermometer sleeve will produce fatigue fracture, and the thermometer inserted in the thermometer sleeve will be damaged, affecting the temperature measurement, and even causing an accident.

[0049] In order to solve the above problems, Figure 1 to Figure 6As shown, this embodiment provides a temperature measuring component installation structure 1000. The temperature measuring component installation structure 1000 includes a mounting portion 200 and a sleeve portion 100 connected in sequence, a receiving cavity 300 is provided in the temperature measuring component installation structure 1000, the receiving cavity 300 penetrates the mounting portion 200 and blocks the sleeve portion 100, the temperature measuring component 2000 can be accommodated in the receiving cavity 300 and detachably fixed with the mounting portion 200, the sleeve portion 100 can extend into the fluid to be measured, a guide groove 110 is provided on the outer peripheral wall of the sleeve portion 100, the guide groove 110 extends along the radial direction of the sleeve portion 100 and bends toward the direction close to the mounting portion 200, the fluid to be measured enters from the opening of the guide groove 110 away from the mounting portion 200 and flows out from the opening of the guide groove 110 close to the mounting portion 200, so that the radial force exerted on the sleeve portion 100 by the fluid to be measured in the process of flowing through the guide groove 110 is gradually reduced.

[0050] The temperature measuring component installation structure 1000 is provided with a receiving cavity 300 which penetrates the installation part 200 and is located in the sleeve part 100, and the temperature measuring component 2000 is received in the receiving cavity 300 and detachably fixed to the installation part 200, so that the assembly and fixation of the temperature measuring component installation structure 1000 and the temperature measuring component 2000 are realized. When the sleeve part 100 extends into the fluid to be measured, the temperature measuring component 2000 can measure the temperature of the fluid to be measured. By providing a guide groove 110 on the outer peripheral wall of the sleeve part 100, the guide groove 110 is bent toward the direction close to the installation part 200 while extending radially along the sleeve part 100, and the fluid to be measured is moved away from the installation part 200 through the guide groove 110. The fluid to be measured enters the opening of the guide groove 110 and flows out from the opening of the guide groove 110 close to the mounting portion 200. When the fluid to be measured flows in the guide groove 110, the force exerted by the fluid to be measured on the sleeve portion 100 is divided into radial force and axial force. The radial force will cause the vibration of the sleeve portion 100. Since the guide groove 110 gradually bends toward the direction close to the mounting portion 200, the radial force exerted by the fluid to be measured on the sleeve portion 100 will decrease as the fluid moves along the guide groove 110, thereby reducing the radial vibration of the sleeve portion 100, achieving the effect of vibration reduction, improving the protection of the temperature measuring component mounting structure 1000 and the temperature measuring component 2000, and ensuring the normal temperature measurement.

[0051] In order to facilitate understanding of the force applied when the fluid to be measured flows along the guide groove 110, Figure 5-6 The force exerted by the fluid in the flow guide groove 110 is analyzed. Figure 5 As shown, when the fluid to be measured begins to flow into the guide groove 110 along the guide groove 110 away from the opening of the mounting portion 200, the fluid to be measured flows in the direction of the velocity V. At this time, the flow velocity V of the fluid to be measured is decomposed as follows:

[0052] V=V1+V2+non-directional velocity when the fluid to be measured is non-uniform=V*cosβ+V*sinβ+non-directional velocity when the fluid to be measured is non-uniform.

[0053] Wherein, β is the angle between the actual flow direction of the measured fluid and the radial direction of the sleeve 100, V1 = V*cosβ, V2 = V*sinβ. V1 is the radial velocity of the measured fluid relative to the flow guide groove 110, and V2 is the tangential velocity of the measured fluid relative to the flow guide groove 110. Combined with the kinetic energy theorem, the energy law E k =1 / 2mv 2 The larger V1 is, the greater the radial kinetic energy and radial force applied to the sleeve part 100 are, while the increase of V2 will not affect the radial kinetic energy and radial force applied to the sleeve part 100. In addition, when the measured fluid is uneven, the non-directional velocity is very small, so the vibration effect on the sleeve part 100 can be ignored.

[0054] like Figure 6 As shown, after the fluid to be measured flows along the guide groove 110 for a certain distance, the angle β between the actual flow direction of the fluid to be measured and the radial direction of the sleeve part 100 gradually increases. When the actual flow velocity of the fluid to be measured remains unchanged, V*cosβ becomes smaller and smaller, and V*sinβ becomes larger and larger, that is, V1 becomes smaller and smaller, and V2 becomes larger and larger, thereby making the radial kinetic energy and radial force applied to the sleeve part 100 smaller and smaller, thereby achieving the effect of reducing the radial vibration of the sleeve part 100 and improving the protection of the temperature measuring component mounting structure 1000 and the temperature measuring component 2000.

[0055] In an optional embodiment, the straight-line distance between the bottom of the guide groove 110 and the accommodating chamber 300 is 0.5 mm to 1.5 mm. By ensuring that the straight-line distance between the bottom of the guide groove 110 and the accommodating chamber 300 is 0.5 mm to 1.5 mm, it is possible to ensure that the temperature measuring component 2000 accommodated in the accommodating chamber 300 can quickly complete the measurement of the temperature of the fluid to be measured on the basis of achieving effective vibration reduction of the sleeve portion 100. It should be noted that in this embodiment, the straight-line distance between the bottom of the guide groove 110 and the accommodating chamber 300 is 1 mm. In other embodiments, the straight-line distance between the bottom of the guide groove 110 and the accommodating chamber 300 can also be adjusted within the range of 0.5 mm to 1.5 mm according to actual needs, and this embodiment does not make specific limitations.

[0056] As an optional solution, an armor layer is provided between the temperature measuring component 2000 accommodated in the accommodating cavity 300 and the inner cavity wall of the accommodating cavity 300. The armor layer is provided to improve the structural strength of the temperature measuring component 2000 in the accommodating cavity 300, and further improve the protection of the temperature measuring component 2000. The specific structure of the armor layer belongs to the prior art and will not be described in detail here.

[0057] In addition, the outer surface of the sleeve part 100 is coated with a protective film, and the protective film is used to protect the sleeve part 100. By coating the protective film on the outer surface of the sleeve part 100, when the sleeve part 100 extends into the conveying pipeline 3000, it is possible to prevent the fluid to be measured in the conveying pipeline 3000 from corroding the sleeve part 100 or reacting with the sleeve part 100, thereby improving the protection of the sleeve part 100.

[0058] In an optional embodiment, the fluid to be measured is transported by a conveying pipeline 3000, the temperature measuring component mounting structure 1000 is inserted and fixed in the conveying pipeline 3000, and the sleeve portion 100 extends into the fluid to be measured in the conveying pipeline 3000.

[0059] In the present embodiment, the fluid to be measured in the delivery pipeline 3000 is hydrogen. Hydrogen has a relatively active chemical property and has a high reducibility. It is easy to undergo an oxidation substitution reaction with the carbides inside the metal, causing the metal to decarburize and resulting in changes in the mechanical strength of the metal. Therefore, the sleeve portion 100 is made of 316L, and a layer of composite coating of aluminum oxide and chromium oxide is coated on the outer surface of the sleeve portion 100 by hot dip method, which can effectively prevent the sleeve portion 100 from hydrogen embrittlement. In other embodiments, the type of fluid to be measured in the delivery pipeline 3000 can also be adjusted according to actual needs, and a corresponding protective film can be coated on the outer surface of the sleeve portion 100 according to the type of fluid to be measured, which is not specifically limited in this embodiment. The coating principle and coating steps of the hot dip method belong to the prior art and will not be repeated here.

[0060] In addition, in order to further improve the structural strength of the sleeve part 100, in this embodiment, before coating the composite coating of aluminum oxide and chromium oxide on the outer surface of the sleeve part 100, the sleeve part 100 is also hardened. The hardening steps and hardening principles of the hardening treatment belong to the prior art and will not be described in detail here.

[0061] As an optional solution, a plurality of flow guide grooves 110 are provided on the outer peripheral wall of the sleeve portion 100 along its axial direction, and each flow guide groove 110 is bent toward the direction close to the mounting portion 200 while extending along the radial direction of the sleeve portion 100, and the fluid to be measured flows through the plurality of flow guide grooves 110 at the same time. It should be noted that, in the present embodiment, seven flow guide grooves 110 are provided on the outer peripheral wall of the sleeve portion 100 along its axial direction, and each flow guide groove 110 is bent toward the direction close to the mounting portion 200 while extending along the radial direction of the sleeve portion 100. In other embodiments, the specific number of the flow guide grooves 110 can also be adjusted according to actual needs, and this embodiment does not make a specific limitation.

[0062] Combination Figure 1 to Figure 4The specific structure of the mounting portion 200 is described. The mounting portion 200 includes a first mounting portion 210 and a second mounting portion 220, wherein the first mounting portion 210 is connected to the sleeve portion 100, and the second mounting portion 220 is connected to the other end of the first mounting portion 210, and the diameters of the sleeve portion 100, the first mounting portion 210, and the second mounting portion 220 are increased in sequence. By splitting the mounting portion 200 into the first mounting portion 210 connected to the sleeve portion 100 and the second mounting portion 220 connected to the other end of the first mounting portion 210, it is ensured that the diameters of the sleeve portion 100, the first mounting portion 210, and the second mounting portion 220 are increased in sequence. When the sleeve portion 100 needs to be inserted into the conveying pipeline 3000, the second mounting portion 220, the first mounting portion 210, and the sleeve portion 100, whose diameters are reduced in sequence, can provide a moving guide, so that the sleeve portion 100 is convenient for being inserted into the conveying pipeline 3000.

[0063] Furthermore, the outer peripheral wall of the delivery pipe 3000 is wrapped with a heat-insulating layer 3100, and the outer end surface of the second mounting portion 220 is flush with the outer end surface of the heat-insulating layer 3100. By arranging the heat-insulating layer 3100 on the outer peripheral wall of the delivery pipe 3000, the heat preservation of the fluid to be measured in the delivery pipe 3000 can be achieved, and by making the outer end surface of the second mounting portion 220 flush with the outer end surface of the heat-insulating layer 3100, when the temperature measuring component mounting structure 1000 and the delivery pipe 3000 are plugged and fixed, the aesthetics of the assembly of the temperature measuring component mounting structure 1000 and the delivery pipe 3000 can be improved.

[0064] In addition, to further facilitate the sleeve portion 100 to extend into the delivery pipe 3000, the diameter of the sleeve portion 100 gradually decreases from the end connected to the mounting portion 200 to the end extending away from the mounting portion 200. In other embodiments, the sleeve portion 100 may also be a straight cylinder, which is not specifically limited in this embodiment.

[0065] In this embodiment, if Figure 6 As shown, the diameter of the end of the sleeve portion 100 away from the mounting portion 200 is A, A=20 mm, the diameter of the end of the sleeve portion 100 close to the mounting portion 200 is B, B=30 mm, and the diameter of the first mounting portion 210 is C, C=40 mm. In other embodiments, the specific values ​​of the diameter A, the diameter B, and the diameter C can be adjusted according to the actual type of the fluid to be measured, the temperature of the fluid to be measured, the pressure of the fluid to be measured, and the flow rate of the fluid to be measured, and this embodiment does not specifically limit it.

[0066] As an optional solution, the mounting portion 200 further includes a first transition portion 230 and a second transition portion 240, wherein both ends of the first transition portion 230 are connected to the sleeve portion 100 and the first mounting portion 210, respectively, the diameter of the end of the first transition portion 230 connected to the sleeve portion 100 is the same as the diameter of the sleeve portion 100, the diameter of the end of the first transition portion 230 connected to the first mounting portion 210 is the same as the diameter of the first mounting portion 210, and the diameter of the first transition portion 230 increases from the end connected to the sleeve portion 100 toward The first mounting portion 210 extends and gradually increases, and both ends of the second transition portion 240 are respectively connected to the first mounting portion 210 and the second mounting portion 220. The diameter of the end of the second transition portion 240 connected to the first mounting portion 210 is the same as the diameter of the first mounting portion 210, and the diameter of the end of the second transition portion 240 connected to the second mounting portion 220 is the same as the diameter of the second mounting portion 220. The diameter of the second transition portion 240 extends from the end connected to the first mounting portion 210 toward the second mounting portion 220 and gradually increases.

[0067] By setting a first transition portion 230 between the sleeve portion 100 and the first mounting portion 210, and setting a second transition portion 240 between the first mounting portion 210 and the second mounting portion 220, the edges generated by the different diameters between the sleeve portion 100 and the first mounting portion 210 and the edges generated by the different diameters between the first mounting portion 210 and the second mounting portion 220 can be eliminated, further facilitating the sleeve portion 100 to be extended into the conveying pipe 3000.

[0068] Furthermore, the accommodating chamber 300 includes a first accommodating chamber 310 and a second accommodating chamber 320, wherein the first accommodating chamber 310 is accommodated in the sleeve portion 100, the first transition portion 230, the first mounting portion 210 and the second transition portion 240, the second accommodating chamber 320 is communicated with the first accommodating chamber 310, the second accommodating chamber 320 is accommodated in the second mounting portion 220, the aperture of the second accommodating chamber 320 is larger than the aperture of the first accommodating chamber 310, and the temperature measuring component 2000 includes a temperature measuring portion 2100 and a fixing portion 2200 connected to each other, the temperature measuring portion 2100 is accommodated in the first accommodating chamber 310, and the fixing portion 2200 is accommodated in the second accommodating chamber 320 and is detachably fixed to the second mounting portion 220.

In other embodiments, the specific type of the pipe thread in the second accommodating chamber 320 can also be adjusted according to actual needs, and it is only necessary to ensure that the external thread on the outer peripheral wall of the fixing portion 2200 matches the pipe thread in the second accommodating chamber 320, and the threaded fixing between the second accommodating chamber 320 and the fixing portion 2200 can also be replaced by flange fixing, which is not specifically limited in the present embodiment.

[0069] In an optional embodiment, the accommodating chamber 300 further includes a third accommodating chamber 330, wherein the third accommodating chamber 330 extends inwardly from the outer end surface of the second mounting portion 220 and communicates with the second accommodating chamber 320, and the aperture of the third accommodating chamber 330 is larger than the aperture of the second accommodating chamber 320, and the temperature measuring component 2000 further includes a sealing ring 2300, which is compressed and clamped on the extension of the fixing portion 2200 and the outer end surface of the second mounting portion 220, and the third accommodating chamber 330 is used to accommodate the sealing ring 2300.

[0070] In addition, if Figure 6As shown, the length of the sleeve portion 100 is L, L = 80mm. The length of the mounting portion 200 is H, and the length H of the mounting portion 200 is composed of the length H1 of the first transition portion 230, the length H2 of the first mounting portion 210, the length H3 of the second transition portion 240, and the length H4 of the second mounting portion 220.
