[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This type of integral turbine flowmeter with built-in IC card valve control integrates the turbine flowmeter module and the IC card valve control module into one by setting up an air supply mechanism, etc., eliminating the connectors and additional straight pipe sections between the two, greatly simplifying the installation steps and improving the installation efficiency. In addition, when it is necessary to connect the integral turbine flowmeter with built-in IC card valve control to the joint flange of the external pipeline, first align the end of the shell with the joint flange, and align the positioning rod with the positioning hole, then drive the moving ring to move through the moving module, and at the same time, the annular cover and the positioning rod can be pushed by the first spring to move in the direction close to the joint flange. At the same time, When the moving ring moves, the first connecting rod drives the first moving block to move, so that the air in the fixed cover can be squeezed. At the same time, the first one-way valve is closed, and the second one-way valve is closed. At this time, the air in the fixed cover can be squeezed and enter the annular cover through the hose, the round hole and the L-shaped tube, and blown out through the blowing hole, so that the sealing gasket on the end face of the joint flange can be blown and cleaned to ensure the sealing after installation. After the positioning rod is inserted into the positioning hole, when the annular cover and the sealing gasket on the joint flange are against each other, the first spring is gradually compressed. At the same time, the distance between the annular cover and the moving ring gradually becomes smaller, which can provide a pre-tightening force, making the connection more stable and reliable. , the connection effect is better, at this time, the top of the sliding plate can slide along the first inclined plate to the bottom of the flat plate, so that the sliding plate can be pushed to move downward, so that the round hole is staggered with the hose and the L-shaped tube, so that the sliding plate can seal the hose and the L-shaped tube. At this time, the on-off mechanism is disconnected, and at the same time, the third spring is compressed. When the moving ring moves, it can drive the first moving block to continue to squeeze the air in the fixed cover, so that the air in the fixed cover is pressurized, and as the pressure in the fixed cover gradually increases, it can push the moving rod to move outward, and at the same time, drive the second moving block to move along the first T-shaped guide rod in the direction away from the fixed cover, and at the same time When the second spring is compressed, the pointer can be driven to move. After the top of the sliding plate slides along the flat plate to the side wall of the second inclined plate and disengages from the second inclined plate, the sliding plate can move upward and reset under the action of the third spring, and make the circular hole align with the L-shaped tube and the hose again. At this time, the on-off mechanism is opened, and the compressed air in the fixed cover can enter the annular cover through the hose, the circular hole and the L-shaped tube, and the blowing hole enters between the annular cover and the sealing gasket. After the pointer stabilizes, by observing whether the pointer continues to move, it can be determined whether there is an air leakage between the annular cover and the joint flange, thereby facilitating the detection of the sealing after connection and ensuring the connection effect.

[0016] (2) This type of integral turbine flowmeter with built-in IC card valve control is provided with a limit mechanism, etc., so that when the positioning rod is inserted into the positioning hole during connection, and the annular cover abuts against the sealing gasket at the end of the joint flange, the distance between the annular cover and the movable ring gradually becomes smaller. At this time, the support block can drive the push rod to abut against the third inclined plate, so that the third movable block can be pushed to move in the direction close to the fixed block. At the same time, the second connecting rod drives the fourth movable block to move, and then the telescopic mechanism drives the fifth movable block and the limit rod to move, and the limit rod can be inserted into the limit hole. Under the action of the first spring, the limit rod abuts against the side wall of the limit hole to achieve a limit effect, which is more stable and reliable, ensuring the connection effect. After being inserted into the limiting hole, when the moving ring continues to move, the fifth spring can be compressed to ensure the normal movement of the moving ring, and during use, when the sealing gasket between the annular cover and the joint flange is worn, looseness will occur. Under the action of the first spring, the annular cover can be pushed to continue to move, so that the sealing gasket on the annular cover and the joint flange always abuts against each other to ensure the connection effect, and when the annular cover moves, it can drive the positioning rod to move synchronously, and when the inclined surface abuts against the side wall of the limiting hole, it can push the limiting rod to withdraw from the limiting hole and slide on the side wall of the positioning rod. At the same time, the fifth spring is compressed, and when the limiting rod is aligned with the limiting hole again, under the action of the fifth spring, the limiting rod can be inserted into the limiting hole again for limiting.

[0030] Working principle: When in use, the turbine flowmeter module 102 and the IC card valve control module 103 are integrated into one, eliminating the connector and the extra straight pipe section between the two, greatly simplifying the installation steps and improving the installation efficiency. Moreover, when it is necessary to connect the integral turbine flowmeter with IC card valve control to the joint flange 11 of the external pipeline, first align the end of the shell 101 with the joint flange 11, and align the positioning rod 1204 with the positioning hole 1101, then, the moving module 1205 drives the moving ring 1201 to move, and at the same time, the first spring 1208 can push the ring The cover 1202 and the positioning rod 1204 move in the direction close to the joint flange 11. At the same time, when the moving ring 1201 moves, the first moving block 202 is driven to move by the first connecting rod 203, so that the air in the fixed cover 201 can be squeezed. At the same time, the first one-way valve is closed, and the second one-way valve is closed. At this time, the air in the fixed cover 201 can be squeezed and enter the annular cover 1202 through the hose 205, the circular hole 502 and the L-shaped tube 204, and blow out the blowing hole 1203, so that the sealing gasket on the end face of the joint flange 11 can be blown and cleaned to ensure the sealing after installation; After the positioning rod 1204 is inserted into the positioning hole 1101, when the annular cover 1202 is against the sealing gasket on the joint flange 11, the first spring 1208 is gradually compressed. At the same time, the distance between the annular cover 1202 and the moving ring 1201 gradually becomes smaller, which can provide a pre-tightening force, making the connection more stable and reliable, and the connection effect is better. At this time, the top of the sliding plate 501 can slide along the first inclined plate 703 to the bottom of the flat plate 702, thereby pushing the sliding plate 501 to move downward, so that the circular hole 502 is staggered with the hose 205 and the L-shaped tube 204, so that the sliding plate 501 can block and seal the hose 205 and the L-shaped tube 204. At this time, the on-off mechanism is disconnected, and at the same time, the third spring 604 is compressed. When the moving ring 1201 moves, it can drive the first moving block 202 to continue to squeeze the air in the fixed cover 201, so that the air in the fixed cover 201 is pressurized. As the pressure in the fixed cover 201 gradually increases, the moving rod 301 can be pushed to move outward, and at the same time, the second moving block 302 is driven to move along the first T-shaped guide rod 401 in a direction away from the fixed cover 201. At the same time, the second spring 402 is compressed and can drive the pointer 304 to move. After the top of the sliding plate 501 slides along the flat plate 702 to the side wall of the second inclined plate 704 and separates from the second inclined plate 704, the sliding plate 501 can move upward and reset under the action of the third spring 604, so that the circular hole 502 is aligned with the L-shaped tube 204 and the hose 205 again. At this time, the on-off mechanism is opened, and the compressed air in the fixed cover 201 can enter the annular cover 1202 through the hose 205, the circular hole 502 and the L-shaped tube 204, and the blowing hole 1203 enters between the annular cover 1202 and the sealing gasket. After the pointer 304 is stable, by observing whether the pointer 304 continues to move, it can be determined whether there is leakage between the annular cover 1202 and the joint flange 11, so as to facilitate the detection of the sealing after connection and ensure the connection effect; Furthermore, when the connection is being made, when the positioning rod 1204 is inserted into the positioning hole 1101, and the annular cover 1202 abuts against the sealing gasket at the end of the joint flange 11, the distance between the annular cover 1202 and the movable ring 1201 gradually becomes smaller. At this time, the push rod 907 can be driven by the support block 906 to abut against the third inclined plate 905, so that the third movable block 802 can be pushed to move in the direction close to the fixed block 901. At the same time, the fourth movable block 804 is driven to move by the second connecting rod 803, and then the fifth movable block 805 and the limiting rod 806 are driven to move by the telescopic mechanism, and the limiting rod 806 can be inserted into the limiting hole 801, and under the action of the first spring 1208, the limiting rod 806 is abutted against the side wall of the limiting hole 801, so as to achieve a limiting effect, which is more stable and reliable, and ensures the connection effect. After the limit rod 806 is inserted into the limit hole 801, when the moving ring 1201 continues to move, the fifth spring 1003 can be compressed to ensure the normal movement of the moving ring 1201. In addition, during use, when the sealing gasket between the annular cover 1202 and the joint flange 11 is worn, loosening will occur. Under the action of the first spring 1208, the annular cover 1202 can be pushed to continue to move, so that the annular cover 1202 and the sealing gasket on the joint flange 11 are always against each other to ensure the connection. The effect is achieved, and when the annular cover 1202 moves, it can drive the positioning rod 1204 to move synchronously. When the inclined surface 807 abuts against the side wall of the limiting hole 801, the limiting rod 806 can be pushed to withdraw from the limiting hole 801 and slide on the side wall of the positioning rod 1204. At the same time, the fifth spring 1003 is compressed. When the limiting rod 806 is aligned with the limiting hole 801 again, under the action of the fifth spring 1003, the limiting rod 806 can be inserted into the limiting hole 801 again for limiting. During disassembly, the movable ring 1201 is driven by the movable module 1205 to move away from the joint flange 11. At this time, the first movable block 202 can be driven to move away from the fixed cover 201. At the same time, the first one-way valve is opened and the second one-way valve is closed, so that external air can enter the fixed cover 201 through the intake pipe 207 for temporary storage.
