Technical Field

[0001] The utility model relates to the field of ultrasonic flowmeters, in particular to a gas ultrasonic flowmeter with a detachable meter head. Background Art

[0002] Gas ultrasonic flowmeter, also known as gas ultrasonic flowmeter, is a process control instrument that uses the principle of ultrasonic velocity difference method to detect and measure gas flow. The measuring pipe section of the flowmeter is equipped with one or more pairs of ultrasonic transducers. The ultrasonic transducers alternately transmit and receive ultrasonic waves. The ultrasonic detection technology is used to measure the sound velocity difference of ultrasonic waves propagating in the forward and reverse directions of the airflow, as well as the fluid pressure and temperature of the measuring pipe section, including the molar components of the gas, to calculate the gas flow rate and the gas flow under standard conditions.

[0003] A Chinese patent with publication number CN216925679U discloses a gas ultrasonic flow meter with easily detachable meter head. The patent drives a push plate to slide on the inner side of a limit groove through a pressing component in a disassembly mechanism, so that the push plate pushes a limit block in the limit assembly to slide on the inner side of the slide groove, so that the limit block retracts into the interior of the slide groove. The pressing block is released, and the push plate returns to its original position under the action of a second spring. Then, the fixing column is pulled to drive the connecting block to be removed from the inner side of the connecting groove. In this way, the meter head body can be quickly disassembled through the fixing column, and the disassembly speed is fast, saving time and effort.

[0023] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a gas ultrasonic flowmeter with a conveniently detachable meter head by improvement. The technical solution of the present utility model is:

[0025] As Figures 1 - 4 shown, a detachable head gas ultrasonic flowmeter includes a gas ultrasonic flowmeter body 1. A fixed sleeve 2 is fixedly connected to the gas ultrasonic flowmeter body 1. A connecting column 3 is movably inserted into the fixed sleeve 2. A head body 4 is fixedly connected to the connecting column 3. A connecting component 5 is provided on the fixed sleeve 2. The connecting component 5 includes a groove 51, a first chute 52, a second chute 53, a through hole 54, a slider 57, a first spring 59 and a clamping block 510. The groove 51 is opened in the fixed sleeve 2. The connecting column 3 is slidably connected in the groove 51. Two first chutes 52 are opened in the fixed sleeve 2. Two second chutes 53 are opened in the fixed sleeve 2. The bottom of the first chute 52 is connected to one side of the second chute 53. Two through holes 54 are opened in the fixed sleeve 2. The two through holes 54 are symmetric about the groove 51. The length of the through hole 54 plus the radius of the groove 51 is equal to the diameter of the fixed sleeve 2. Two sliders 57 are fixedly connected to the connecting column 3. The width of the slider 57 is the same as the width of the first chute 52. The height of the slider 57 is the same as the height of the second chute 53. The two sliders 57 are respectively slidably connected in the two first chutes 52 and the second chute 53. Two first springs 59 are fixedly connected in the connecting column 3. Two clamping blocks 510 are slidably connected in the connecting column 3. The two clamping blocks 510 are respectively fixedly connected to the two first springs 59. An auxiliary component 6 is provided in the fixed sleeve 2.

[0026] Furthermore, as Figures 1 - 4 shown, the connecting component 5 further includes a push rod 55 and a limiting rod 56. The two push rods 55 are respectively slidably connected in the two through holes 54. The two limiting rods 56 are respectively slidably connected in the two through holes 54. The limiting rod 56 and the push rod 55 are vertically distributed. The two limiting rods 56 are respectively fixedly connected to the two push rods 55.

[0027] Furthermore, as Figure 4 shown, the connecting component 5 further includes a clamping groove 58 and a limiting block 511. The two clamping grooves 58 are opened on the connecting column 3. The two clamping grooves 58 are symmetric about the connecting column 3. The two clamping blocks 510 are respectively slidably connected in the two clamping grooves 58. The two limiting blocks 511 are respectively fixedly connected to the two clamping blocks 510. The two limiting blocks 511 are respectively slidably connected in the two clamping grooves 58.

[0028] Furthermore, as Figure 3 shown, the auxiliary component 6 includes a limiting groove 61 and a second spring 62. Four limiting grooves 61 are opened in the fixed sleeve 2. The limiting grooves 61 are distributed in an annular array with the center of the fixed sleeve 2 as the center of the circle. The cross section of the limiting groove 61 is in the shape of a "convex". Four second springs 62 are fixedly connected in the four limiting grooves 61.

[0029] Furthermore, as Figures 1 - 4As shown, the auxiliary component 6 further includes a sliding plate 63 and a support rod 64. The four sliding plates 63 are respectively slidably connected to the four limiting grooves 61, and the four sliding plates 63 are respectively fixedly connected to the four second springs 62. The diameter of the sliding plate 63 is larger than that of the support rod 64. The four support rods 64 are respectively slidably connected to the four limiting grooves 61, and the four support rods 64 are respectively fixedly connected to the four sliding plates 63.

[0030] Further, as Figures 1 - 4 shown, the auxiliary component 6 further includes a support plate 65 and a rubber pad 66. The four support plates 65 are respectively fixedly connected to the four support rods 64, and the four rubber pads 66 are respectively fixedly connected to the four support rods 64. The rubber pad 66 has a soft texture and can reduce damage to the meter head body 4.

[0031] The specific working method is as follows: Insert the connecting column 3 into the groove 51, ensuring that the slider 57 on the connecting column 3 and the first sliding groove 52 are on the same vertical line. As the connecting column 3 is inserted into the groove 51, the slider 57 slides in the first sliding groove 52. The inner wall of the fixed sleeve 2 contacts the inclined surface of the clamping block 510, pushing the clamping block 510 into the clamping groove 58. When the bottom of the connecting column 3 fits with the bottom of the groove 51, the bottom of the slider 57 fits with the bottom of the first sliding groove 52. Then, rotate the connecting column 3 clockwise, causing the slider 57 to slide in the second sliding groove 53. When one side of the slider 57 fits with one side of the second sliding groove 53, the clamping block 510 meets the through hole 54. Under the action of the first spring 59, the clamping block 510 moves towards the push rod 55, pushing the push rod 55 to move outwards. The clamping block 510 is inserted into the through hole 54, making the connecting column 3 unable to rotate. At this time, the slider 57 is located in the second sliding groove 53, making the connecting column 3 unable to move up and down, thus realizing the fixation of the connecting column 3, that is, completing the installation of the meter head body 4. When it is necessary to disassemble the meter head body 4, move the push rod 55 towards the clamping block 510, causing the clamping block 510 to be inserted into the clamping groove 58. At this time, the connecting column 3 can be rotated counterclockwise, causing the slider 57 to slide along the second sliding groove 53. When the slider 57 slides to the bottom of the first sliding groove 52, the connecting column 3 is no longer restricted. The second spring 62 rebounds, pushing the sliding plate 63 upwards, driving the support rod 64 and the support plate 65 upwards. The support plate 65 will push the meter head body 4 upwards, driving the connecting column 3 upwards, and pulling the connecting column 3 out of the groove 51, thus completing the disassembly of the meter head body 4.

Matters not covered in the present utility model belong to the common general knowledge of those skilled in the art.
