[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1-4As shown, this utility model provides a metal scraper flowmeter with a sampling port, including a flowmeter housing 1 and a fixing block 2. The fixing block 2 is fixedly mounted on the flowmeter housing 1 and communicates with the metering cavity of the flowmeter housing 1. A sampling tube 3 is fixedly mounted on one end of the fixing block 2, and one end of the sampling tube 3 is connected to the inner cavity of the fixing block 2. When the bottom end of the sampling tube 3 is open, the medium in the inner cavity of the flowmeter housing 1 can flow out through the fixing block 2 and the sampling tube 3. The inner diameter of the sampling tube 3 is smaller than the inner diameter of the fixing block 2. A discharge pipe 31 is fixedly mounted on one end of the sampling tube 3. When the medium enters the inner cavity of the sampling tube 3, the medium can flow downward through the discharge pipe 31, thus discharging the sample. The sampling tube 31 is inclined downwards, which facilitates the outflow of the medium. One end of the sampling tube 31 is provided with a cap 32, which is threaded and rotatably installed at one end of the sampling tube 31. By providing a threaded and removable cap 32, the end of the sampling tube 31 can be sealed to prevent impurities and dust from entering the inner cavity of the sampling tube 3. A liquid level window 33 is provided on the tube body of the sampling tube 3. By providing a liquid level window 33, it is easy to observe the medium flowing through the inner cavity of the sampling tube 3. A sampling component 4 is provided on the sampling tube 3. By providing a sampling component 4, the sampling component 4 can control the opening and closing of the bottom end of the sampling tube 3. When it is open, the medium flows out, and sampling can be achieved.

[0024] The sampling assembly 4 includes a fixed plate 41. The lower surface of the fixed plate 41 is in movable contact with the other end of the sampling tube 3. A collar 42 is fixedly mounted on the lower surface of the fixed plate 41. The inner wall of the collar 42 is in movable contact with the outer wall of the other end of the sampling tube 3. Several assembly bolts 43 are threadedly mounted between the collar 42 and the other end of the sampling tube 3. By setting the assembly bolts 43, the collar 42 and the fixed plate 41 can be installed on the top end of the sampling tube 3, and the collar 42 and the fixed plate 41 can be disassembled. A cylinder mounting bracket 44 is detachably mounted on the upper surface of the fixed plate 41. A cylinder 441 is detachably mounted on one end of the mounting bracket 44 via bolts. A positioning plate 45 is detachably mounted on the piston end of the cylinder 441. By activating the cylinder 441, the piston end of the cylinder 441 extends and retracts, enabling the positioning plate 45 to vertically rise and fall within the inner cavity of the sampling tube 3. The positioning plate 45 is located within the inner cavity of the other end of the sampling tube 3. A first sealing sleeve 46 is fixedly installed on the outer wall of the positioning plate 45. The outer wall of the first sealing sleeve 46 is in movable contact with the inner wall of the other end of the sampling tube 3. By setting the first sealing sleeve 46, the first sealing sleeve 46 can improve the positioning plate 45 and the sampling tube 3. The sealing between the inner walls is achieved by adhesively fixing the first sealing sleeve 46 to the outside of the positioning plate 45. Once the positioning plate 45 detaches from the inner cavity of the sampling tube 3, the first sealing sleeve 46 can be replaced. A fixing rod 47 is fixedly installed on the lower surface of the positioning plate 45, and a piston plate 48 is fixedly installed at one end of the fixing rod 47. The piston plate 48 is located in the inner cavity of one end of the sampling tube 3. When the positioning plate 45 moves vertically up and down in the inner cavity of the sampling tube 3, the positioning plate 45 can synchronously raise and lower the piston plate 48 via the fixing rod 47. When the piston plate 48 is located above the discharge tube 31... The medium in the metering chamber of the flowmeter housing 1 enters the inner cavity of the sampling tube 3 through the fixing block 2, and then is discharged outward through the discharge pipe 31. A second sealing sleeve 49 is fixedly installed on the outer wall of the piston disc 48. The outer wall of the second sealing sleeve 49 is in contact with the inner wall of one end of the sampling tube 3. By setting the second sealing sleeve 49, the sealing performance between the piston disc 48 and the inner wall of the sampling tube 3 can be improved, and the medium overflow is prevented. The second sealing sleeve 49 is fixed to the outside of the piston disc 48 by adhesive. When the piston disc 48 is separated from the inner cavity of the sampling tube 3, the second sealing sleeve 49 can be replaced.

[0025] Working principle: When sampling is required, the operator first rotates the cap 32 counterclockwise to disengage the cap 32 from the end of the discharge tube 31. Then, the cylinder 441 is activated, the piston end of the cylinder 441 retracts, and the piston end of the cylinder 441 pulls the positioning plate 45 upward. The positioning plate 45 raises the piston plate 48 vertically through the fixing rod 47. When the upper surface of the positioning plate 45 contacts the lower surface of the fixing plate 41, the piston plate 48 is located above the discharge tube 31. At this time, the cylinder 441 is closed, and the medium in the metering chamber of the flow meter housing 1 flows into the bottom end of the sampling tube 3 through the fixing block 2, and then is discharged outward through the discharge tube 31. The discharged medium sample is stored in a container.

[0026] After sampling is completed, the operator restarts cylinder 441, causing the piston end of cylinder 441 to extend and push the positioning plate 45 to descend and reset. The positioning plate 45, through the fixing rod 47, causes the piston plate 48 to descend and reset, thus closing the bottom end of the sampling tube 3.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
