Description

Technical Field

[0001] This utility model relates to the field of ultrasonic technology, specifically to an installation assembly for an insertion-type ultrasonic flow meter for heating network supply and return water flow. Background Technology

[0002] An ultrasonic flow meter is a velocity-type flow meter that uses ultrasonic pulses to measure the flow rate of liquids. It entered my country's industrial production and metering fields in the 1980s and experienced rapid development in the 1990s. Before using an ultrasonic flow meter, it's essential to understand its relevant knowledge, including its applications, classifications, characteristics, and principles, to better apply it in real-world situations. Conventional pipe-section ultrasonic flow meters integrate the transducer and measuring tube. However, some pipes, due to porous materials, poor sound conduction, severe corrosion, or gaps between the lining and the pipe's internal space, experience significant ultrasonic signal attenuation, making clamp-on ultrasonic flow meters unusable. Insertion ultrasonic flow meters, on the other hand, can be installed without interrupting the flow. A hole is drilled in the water-filled pipe using specialized tools, and the transducer is inserted into the pipe. Because the transducer is inside the pipe, its signal transmission and reception only pass through the measured medium, not the pipe wall or lining, thus its measurement is not limited by the pipe quality or lining material.

[0003] Existing insertion ultrasonic flow meters require drilling holes in the pipe during installation. After drilling, when the rotor is pulled out, some liquid will flow out of the pipe, causing pollution to the working environment. Utility Model Content

[0004] The purpose of this utility model is to provide an installation component for an insertion ultrasonic flow meter for heating network supply and return water flow, in order to solve the problem mentioned in the background art that the existing insertion ultrasonic flow meter requires drilling holes in the pipe before installation. After drilling, when the rotor is pulled out, some liquid will flow out of the pipe, causing pollution to the working environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation assembly for an insertion-type ultrasonic flow meter for heating network supply and return water flow, comprising a pipe body, with fixed flanges fixedly installed on both sides of the pipe body, and ball valves bolted to one end of each of the two fixed flanges, with connecting threads on the outer ring of one end of each ball valve, and an ultrasonic flow meter threaded to one end of one ball valve, and a water collection device snapped onto one end of the other ball valve.

[0006] Preferably, the water collection device includes a water storage tank, the bottom of which is fixedly connected to a guide pipe, and a guide pipe is fixedly installed at the top of one end of the water storage tank. The guide pipe has an outlet in its inner cavity to facilitate the discharge of wastewater from the pipe.

[0007] Preferably, a fixing frame is fixedly connected to the bottom of one end of the water storage tank, a rebound device is fixedly installed on the inner wall of one end of the water storage tank, and a baffle plate is fixedly installed on the top of the rebound device to prevent splashing when wastewater is discharged.

[0008] Preferably, one end of the fixing frame is fixedly connected to a ring buckle, and a first locking pin and a second locking pin are fixedly provided on one side of the ring buckle. A locking block is fixedly provided at the bottom of the first locking pin, and a locking groove is opened in the middle of the second locking pin. A second spring is fixedly provided at the bottom of the locking groove. The water collection device is installed on the ball valve through the ring buckle.

[0009] Preferably, the second locking pin has sliding grooves on both sides, a baffle is fixedly provided in the middle of the sliding groove, a pin is slidably connected to the middle of the baffle, a second spring is fixedly provided at one end of the baffle, and a locking block is fixedly connected to one end of the pin, so as to facilitate locking the ring buckle.

[0010] Preferably, the outer ring of the pin is fitted with a first spring, which is located between the baffle and the locking block, and the locking block matches the locking groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: at the moment the drill bit is completed and pulled out, the wastewater flowing out of the pipe will be accurately guided into the water collection device. The water collection device is equipped with a water storage tank and a guide pipe, which can collect the wastewater and guide it into the collection device through the guide pipe, thus preventing the wastewater from flowing out indiscriminately. It can be easily connected to the drainage pipe to guide the collected wastewater to the designated treatment location, which greatly simplifies the subsequent cleaning process, effectively saves manpower and time costs, and makes the installation process of the insertion ultrasonic flow meter more efficient, convenient and environmentally friendly.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-4 This utility model provides an installation assembly for an insertion-type ultrasonic flow meter for the supply and return water flow of a heating network. It includes a pipe body 1, with fixed flanges 2 fixedly installed on both sides of the pipe body 1. A ball valve 3 is bolted to one end of each of the two fixed flanges 2. A connecting thread 4 is provided on the outer ring of one end of the ball valve 3. An ultrasonic flow meter 5 is threaded to one end of one ball valve 3, and a water collection device is snapped onto one end of the other ball valve 3. The water collection device includes a water storage tank 6. A guide pipe 7 is fixedly connected to the bottom of the water storage tank 6. A guide pipe 8 is fixedly installed at the top of one end of the water storage tank 6. An outlet 9 is opened in the inner cavity of the guide pipe 8. A fixing bracket 13 is fixedly connected to the bottom of one end of the water storage tank 6. A rebounder 11 is fixedly installed on the inner wall of one end of the water storage tank 6, and a baffle plate 10 is fixedly installed on the top of the rebounder 11.

[0019] In this embodiment, the following steps are taken: First, remove the fixed flange 2 from the equipment. Then, weld the fixed flange 2 onto the pipe body 1. Install the ball valve 3 on the fixed flange 2 and tighten all M16 bolts diagonally (maximum torque 14 Nm). Check that the ball valve 2 is in the open position. Install a pressure tap to the fixed flange 2 position of the ball valve 3. Carefully drill a 45 mm diameter hole in the pipe wall. To reduce drilling burrs, use a grooved bimetallic drill or a carbide saw. Pull out the cut pipe wall and drill bit together. Close the valve and remove the hot drilling tap. Install the base and sensor together on the valve. Check / tighten all M16 bolts diagonally (maximum torque 14 Nm). If the maximum torque of the M12 bolts is 12 Nm, open the valve and position it.

[0020] Please see Figure 1-4Furthermore, one end of the fixing frame 13 is fixedly connected to a ring buckle 12, and a first locking pin 15 and a second locking pin 16 are fixedly provided on one side of the ring buckle 12. A locking block 22 is fixedly provided at the bottom of the first locking pin 15. A locking groove 21 is opened in the middle of the second locking pin 16. A second spring 20 is fixedly provided at the bottom of the locking groove 21. Sliding grooves 23 are opened on both sides of the second locking pin 16. A baffle 17 is fixedly provided in the middle of the sliding groove 23. A pin 14 is slidably connected in the middle of the baffle 17. A second spring 20 is fixedly provided at one end of the baffle 17. A locking block 19 is fixedly connected at one end of the pin 14. A first spring 18 is sleeved on the outer ring of the pin 14. The first spring 18 is located between the baffle 17 and the locking block 19. The locking block 22 matches the locking groove 21.

[0021] In this embodiment of the application, when the pin 14 is pulled, the pin 14 causes the locking block 19 to press the first spring 18 to the baffle 17, so that the locking block 19 enters the sliding groove 23, releasing the restriction on the locking block 22. After the restriction is released, the second spring 20 releases its elastic force, so that the locking block 22 pops out of the locking groove 21, making it easier for the first locking pin 15 to disengage from the second locking pin 16 and open the ring buckle 12.

The wastewater enters the water storage tank 6 from the outlet 9 and then exits through the guide pipe 7. During exiting, the baffle plate 10 can effectively prevent splashing of wastewater. After exiting, pull the pin 14, so that the pin 14 drives the locking block 19 to squeeze the first spring 18 to the baffle plate 17, so that the locking block 19 enters the sliding groove 23, releasing the limit on the locking block 22. After release, the second spring 20 releases its elastic force, so that the locking block 22 pops out of the locking groove 21, making it easy for the first locking pin 15 to disengage from the second locking pin 16 to open the ring buckle 12. Finally, the base and sensor are installed on the valve together. Check / tighten all M16 bolts diagonally (maximum torque 14 Nm). If M12 The maximum bolt torque is 12 Nm.
