Multi-probe compatible high-temperature test tool for steam vortex flowmeter

Abstract

The present application provides a steam vortex flowmeter multi-probe compatible high-temperature test tool, relates to the technical field of vortex probe test tool, and comprises a rotating frame. The rotating frame is designed as a multi-prism structure, and installation groove holes with decreasing sizes are arranged on each end face. Different specifications of installation groove holes can be exchanged by rotating the rotating frame, so that they coincide with the insertion hole of the meter body. The steam vortex flowmeter probe of different models and sizes can be adapted without replacing the entire test tool. The quick adaptation and installation of different probes can be completed by only rotating adjustment, the structure design of the test device has strong pertinence, and only a single model and specification of vortex probe can be installed and adapted. The adaptation range is narrow. When different models and sizes of probes need to be tested, the entire test tool needs to be replaced, which not only increases the test cost but also greatly reduces the test efficiency, and the batch test demand of multi-specification probes cannot be considered.

Description

Technical Field

[0001] This invention relates to the field of vortex probe testing fixture technology, and particularly to a multi-probe compatible high-temperature testing fixture for steam vortex flow meters. Background Technology

[0002] As a flow measurement instrument widely used in industries such as petroleum, chemical, and power, the measurement accuracy of the probe of the steam vortex flow meter directly affects the reliability of the entire flow measurement system. The core purpose of this test fixture is to provide a performance testing platform for the steam vortex flow meter probe under high-temperature conditions, simulate actual working conditions (such as high-temperature steam medium environment), and test the measurement accuracy and stability of the probe under the corresponding environment, so as to provide support for the production, debugging, and performance verification of the probe.

[0003] Currently, existing steam vortex flow meter probe testing fixtures on the market have significant technical defects and are difficult to meet actual testing needs: First, the existing testing equipment is designed to be highly specific, and can usually only be installed to fit a single model and specification of vortex shear probe. The range of compatibility is narrow. When it is necessary to test probes of different models and sizes, the entire set of testing fixtures must be replaced, which not only increases the testing cost, but also significantly reduces the testing efficiency. It cannot meet the batch testing needs of probes of multiple specifications. Secondly, the actual working environment of steam vortex flowmeters is often accompanied by high-temperature conditions. The probe testing process needs to simulate this high-temperature environment. However, the structural design of the existing test fixture is not fully adapted to this high-temperature scenario. When used in a high-temperature environment for a long time, some connecting parts of the test fixture are prone to thermal deformation due to high temperature, resulting in dimensional tolerance deviations of the parts. After the parts are deformed, the sealing performance of the test device will be greatly reduced, and the steam medium will leak from the gaps between the parts, destroying the sealing and stability of the test environment. This will interfere with the probe's measurement signal, resulting in inaccurate test results that cannot truly reflect the probe's working performance under actual high-temperature conditions, thus affecting the quality control of the probe at the factory. Summary of the Invention

[0004] To address the above problems, one objective of this invention is to overcome these shortcomings, and more specifically, to provide a multi-probe compatible high-temperature testing fixture for steam vortex flow meters.

[0008] Preferably, a through-hole is provided at the upper end of the annular groove on the outer side of the watch body, and a fixing ring is provided on the inner right side of the annular groove, the size of which matches that of the movable ring.

[0009] Preferably, the rotating frame has a prismatic structure, and annular mating grooves are provided on both sides of the rotating frame. The mating groove on the left side abuts against the part of the movable ring extending from the inner groove, and the mating groove on the right side abuts against the fixed ring.

[0010] Preferably, a mounting slot is provided at the middle position of the outer end face of the rotating frame, and the mounting slots on each outer end face of the rotating frame are arranged in a decreasing order. The mounting slot penetrates the rotating frame, and a rubber pad is provided on the outside of the mounting slot. The rubber pad can contact the lower end face of the outer annular structure of the probe.

[0011] Preferably, two sets of movable slots are symmetrically arranged on each end face of the rotating frame. The movable slots on each end face are located on both sides of the mounting slot hole. A vertical frame is slidably arranged on each movable slot through an elastic element. The vertical frame can slide horizontally on the rotating frame along the movable slot.

This ring, in conjunction with a fixed ring on the right side of the annular groove of the meter body, ensures that the mating grooves on both sides of the rotating frame are tightly abutted against the movable and fixed rings. The movable ring can compensate for gaps caused by high-temperature deformation of components in real time using elastic force, preventing steam leakage from the mating point between the rotating frame and the meter body. Simultaneously, a rubber pad is placed outside the mounting slot, and through the cooperation of the stand, pressure plate, and spring, the outer annular structure of the probe is always tightly fitted to the rubber pad. The pressure plate can apply pressure in real time, preventing gaps between the probe and the mounting slot caused by high-temperature deformation, ensuring the airtightness of the probe installation, preventing steam leakage from interfering with the measurement signal, and ensuring the sealing and stability of the testing environment under high-temperature testing conditions. This, in turn, guarantees the accuracy of the probe measurement results and truly reflects the probe's performance under actual high-temperature conditions. Attached Figure Description

Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figures 1 to 8 As shown: This invention provides a multi-probe compatible high-temperature testing fixture for a steam vortex flow meter, comprising: a meter body 1; the meter body 1 has a cylindrical structure and is entirely made of metal, with flanges on both sides, an annular groove on the outer right side of the meter body 1, and a vortex generator 101 inside the meter body 1; a rotating frame 2 is disposed in the annular groove on the outer right side of the meter body 1, the rotating frame 2 can fit against the outer wall of the meter body 1 and rotate around its axis, and a mounting slot 202 at the upper end of the rotating frame 2 can be connected to the outer wall of the meter body 1.

The detection module 3 is installed at the upper end of the meter body 1. A connecting harness 301 is provided on the right side of the detection module 3. A probe 302 is installed at the end of the connecting harness 301. The probe 302 is electrically connected to the detection module 3 through the connecting harness 301. The probe 302 is located at the upper end of the rotating frame 2, and the lower end of the probe 302 passes through the mounting slot 202 and the socket 104 at the upper end of the rotating frame 2 and extends into the interior of the meter body 1.

[0027] As a second embodiment of the present invention, based on the first embodiment, such as Figure 4 and Figure 6As shown, two sets of adjusting grooves 102 are provided on the right flange of the dial body 1. A screw 1021 is rotatably installed inside each adjusting groove 102, and a pressure rod 1022 is slidably arranged on each adjusting groove 102. The pressure rod 1022 is threadedly connected to the screw 1021 in the adjusting groove 102, and the pressure rod 1022 abuts against the outer end face of the rotating frame 2. An inner groove 103 is provided on the left inner wall of the outer annular groove of the dial body 1. A movable ring 1031 is slidably arranged in the inner groove 103 through an elastic element. The side end of the movable ring 1031 can extend out of the inner groove 103. The upper end of the annular groove on the outer side of the meter body 1 is provided with a through-hole 104, and a fixing ring 105 is provided on the inner wall of the right side of the annular groove. The size of the fixing ring 105 matches that of the movable ring 1031. The meter body 1 is provided, and a rotating frame 2 can be installed on the meter body 1. A vortex generator 101 is provided. When steam passes through the vortex generator 101, it can generate vortices. The steam flow rate can be judged by the number of vortices generated. An adjusting groove 102 is provided, through which the pressure rod 1022 can be movably installed to the right side of the meter body 1. A screw is provided. 1021, by rotating the screw 1021, the position of the pressure rod 1022 in the adjustment groove 102 can be adjusted, and whether the pressure rod 1022 can press the rotating frame 2 can be controlled; the pressure rod 1022 is provided so that the rotating frame 2 can be fixed at the outer end of the watch body 1 by pressing the pressure rod 1022 against the outer end face of the rotating frame 2; the inner groove 103 is provided so that the movable ring 1031 can be slidably installed onto the watch body 1 through the inner groove 103; the movable ring 1031 is provided so that the fixed ring 105 can be fixed against the rotating frame 2 by pressing the movable ring 1031 against the rotating frame 2. The mating groove 201 on the right side of the frame 2 is tightened to seal the right side of the rotating frame 2. The movable ring 1031 abuts against the mating groove 201 on the left side of the rotating frame 2, and at the same time, it can also seal the right side of the rotating frame 2 to prevent steam from overflowing from both sides of the rotating frame 2. An insertion hole 104 is provided, and by inserting the probe 302 into the insertion hole 104, the flow rate of steam flowing inside the meter body 1 can be measured. A fixing ring 105 is provided, and by abutting the fixing ring 105 against the mating groove 201 on the right side of the rotating frame 2, the right side of the rotating frame 2 can be sealed.

[0028] This application installs a movable ring 1031 in the inner groove 103 of the body 1. With the pushing action of the movable ring 1031, the mating grooves 201 at both ends of the rotating frame 2 can be tightly abutted against the movable ring 1031 and the fixed ring 105 respectively. This can compensate for the gaps caused by the deformation of the parts under high temperature in real time and prevent steam from escaping from the gaps. At the same time, after the probe 302 is inserted into the mounting slot 202, the pressure plate 204 is pressed against the upper end face of the outer annular structure of the probe 302 to ensure that the lower end face of the outer annular structure of the probe 302 is effectively fitted with the rubber pad 2021. This also avoids the gaps caused by high temperature, which would reduce the airtightness of the probe 302 installation.

[0029] As a third embodiment of the present invention, based on embodiment one, such as Figure 8 As shown, the rotating frame 2 has a prismatic structure, and annular mating grooves 201 are provided on both sides of the rotating frame 2. The left mating groove 201 abuts against the part of the movable ring 1031 extending from the inner groove 103, and the right mating groove 201 abuts against the fixed ring 105. A mounting slot 202 is provided in the middle of the outer end face of the rotating frame 2, and the mounting slots 202 on each outer end face of the rotating frame 2 are arranged in a decreasing order. The mounting slot 202 penetrates the rotating frame 2, and a rubber pad 2021 is provided on the outside of the mounting slot 202. The rubber pad 2021 can contact the lower end face of the outer annular structure of the probe 302. Two sets of movable grooves 203 are symmetrically arranged on each end face. The movable grooves 203 on each end face are located on both sides of the mounting slots 202. A support frame 2031 is slidably mounted on each movable groove 203 via an elastic element. The support frame 2031 can slide horizontally along the movable groove 203 on the rotating frame 2. A pressure plate 204 is provided on the inner side of each set of support frames 2031. A pull ring 2041 is fixedly installed on the outside of the pressure plate 204. The pull ring 2041 slides with the support frame 2031. A spring is provided between the pressure plate 204 and the support frame 2031. When the pull ring 2041 is pulled, the pressure plate 204 can slide along the inner wall of the support frame 2031. The probe 302 has an outer annular structure that contacts the upper surface of the probe 302. A multi-prism shaped rotating frame 2 is provided, with mounting slots 202 of different diameters on each prism end face, allowing for the installation of probes 302 of different models and specifications. A mating groove 201 is provided, which, through its contact with the fixing ring 105 and the movable ring 1031, seals both sides of the rotating frame 2. Mounting slots 202 are provided, allowing probes 302 of the appropriate size to be inserted into the body 1 for installation. A rubber pad 2021 is provided, which, by pressing the outer annular structure of the probe 302 against the rubber pad 2021, ensures... The system ensures the sealing of the mounting end face of probe 302; a movable groove 203 is provided, through which the support frame 2031 can be slidably mounted onto the outer surface of the rotating frame 2; the support frame 2031 is provided, on which the pressure plate 204 can be slidably mounted; the pressure plate 204 is provided, which, by pressing against the upper end face of the outer annular structure of probe 302, can apply pressure to probe 302 in real time, so that the lower end face of its outer annular structure always remains in close contact with the rubber pad 2021, thereby maintaining the sealing of the installation; a pull ring 2041 is provided, by pulling the pull ring 2041, the movement of the pressure plate 204 on the support frame 2031 can be controlled.

[0030] This application sets the rotating frame 2 into a polygonal prism structure and sets mounting slots 202 of progressively decreasing size on each end face of the rotating frame 2. During use, by rotating the rotating frame 2, the mounting slots 202 of the corresponding size are rotated to the upper end face of the rotating frame 2 and made to coincide with the insertion hole 104. At this time, the probe 302 of the corresponding size can be inserted into the inside of the meter body 1 through the mounting slots 202 and fixed in the mounting slots 202 at that position by means of the pressure plate 204. When it is necessary to test different models of probes 302, the mounting slots 202 can be changed by rotating the rotating frame 2 to install and adapt them.

[0031] The specific usage and function of this embodiment are as follows: In this invention, such as Figures 1 to 8 As shown, rotating the screw 1021 in the adjustment groove 102 on the right side of the watch body 1 causes the pressure rod 1022 to slide within the adjustment groove 102, thereby loosening the clamping and fixing of the rotating frame 2. Then, rotating the polygonal rotating frame 2, according to the size specifications of the probe 302 to be tested, rotates the corresponding mounting slot 202 to the upper position of the rotating frame 2, ensuring that the mounting slot 202 is aligned and connected with the insertion hole 104 at the upper end of the annular groove on the outer side of the watch body 1. During this process, the movable ring 1031 in the inner groove 103 is subjected to the elastic force of the elastic element. The probe 302 extends automatically and fits tightly into the mating groove 201 on the left side of the rotating frame 2. The mating groove 201 on the right side of the rotating frame 2 naturally fits into the fixing ring 105 on the right side of the annular groove. Rotating the screw 1021 in the opposite direction pushes the pressure rod 1022 to press tightly against the outer end face of the rotating frame 2, thus limiting and fixing the rotating frame 2 on the body 1. Then, the two sets of uprights 2031 are separated, and the pull ring 2041 is pulled, causing the pressure plate 204 to slide upward along the uprights 2031. Then, the probe 302 is inserted into the mounting slot 202. In the middle, let its bottom pass through the insertion hole 104 and extend into the interior of the meter body 1. Then release the pull ring 2041. Under the action of the spring's return force, the pressure plate 204 presses down to the upper end face of the annular structure outside the probe 302, so that its lower end face is tightly fitted with the rubber gasket 2021 outside the mounting slot 202, ensuring installation sealing. Then connect the probe 302 to the detection module 3 at the upper end of the meter body 1 through the connecting wire harness 301. After confirming that the connection is firm, turn on the entire test system and introduce high temperature steam (up to 1000 ℃) into the meter body 1. When the steam flows through the vortex generator 101 inside the body 1 (up to 350℃), it generates regular vortices. The probe 302 detects the signal generated by the vortex in real time and transmits it to the detection module 3 through the connecting wire harness 301. The detection module 3 processes and analyzes the signal to complete the steam flow test. When it is necessary to test different types of probes 302, the above operation steps are repeated. By rotating the rotating frame 2 to change the corresponding size of the mounting slot 202, the matching probe 302 can be installed and tested.

[0032] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
