Description

Technical Field

[0001] This utility model relates to the field of flow detection technology, specifically a gas flow detection device that supports remote control of valve opening. Background Technology

[0002] A gas flow detection device is a key piece of equipment used to accurately measure the flow rate of gas in pipes or equipment.

[0003] Patent CN212058927U discloses a gas flow detection device, including a measuring mechanism comprising a pipe, a gas flow meter, and flanges. Each end of the pipe has a flange, an inlet, and an outlet. A gas flow meter is located near the top of the pipe, detecting the gas flow rate entering through the inlet. A support cover is welded parallel to the gas flow meter at the top of the pipe, and a first housing is connected to the rear of the support cover via screws. This patent employs both a gas flow meter and a flow sensor to achieve dual flow detection, improving the accuracy of flow detection.

[0004] As shown in the above technology, in the use of ordinary cigarette equipment, the valves related to airflow detection can only be controlled on-site and cannot be remotely switched on and off, which is inconvenient for remote use in the control room. In addition, during the detection process, the gas flow rate is sometimes extremely low, making it difficult to achieve high-precision detection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a gas flow detection device that supports remote control of valve opening. This solves the problem that in ordinary cigarette equipment, the valves related to airflow detection can only be controlled locally and cannot be remotely switched on and off, making it inconvenient for remote use in the control room. In addition, during the detection process, the gas flow is sometimes extremely low, making it difficult to achieve high-precision detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas flow detection device supporting remote control of valve opening, comprising:

[0007] The operating pipeline is equipped with a remotely openable and closed valve. A detection bend is connected to the left side of the operating pipeline. A sealing ring is fixedly connected to the inner wall of the detection bend. A flow detection body is connected to one end of the detection bend.

[0008] A cross-section adjustment component is located on the surface of the detection bend, and the cross-section adjustment component is used to adjust the cross-section of the gas flow to more accurately measure the flow rate;

[0009] An auxiliary component is fixedly connected to the surface of the cross-section adjustment component on one side, and the auxiliary component is used to assist in the detection and adjustment process.

[0010] Preferably, the cross-section adjustment assembly includes a support base fixedly connected to the surface of the detection bend, and a sealing plate is fixedly connected to the top of the support base.

[0011] Preferably, an operating unit is fixedly connected to the top of the sealing plate. The operating unit includes a threaded sleeve fixedly connected to the top of the sealing plate. An observation groove is provided on the surface of the threaded sleeve, and a screw passes through the inside of the threaded sleeve.

[0012] Preferably, a handle is fixedly connected to the top end of the screw, and an indicator block is rotatably connected to the bottom end of the screw.

[0013] Preferably, a connecting rod is fixedly connected to the bottom of the indicator block, the bottom end of the connecting rod passes through the detection bend and extends into the interior of the detection bend, and a sealing cone is fixedly connected to the bottom end of the connecting rod.

[0014] Preferably, the auxiliary component includes a display metering plate fixedly connected to the top left side of the sealing plate, and a limit plate fixedly connected to the top right side of the sealing plate.

[0015] This invention provides a gas flow detection device that supports remote control of valve opening. Compared with the prior art, it has the following advantages:

[0016] 1. This gas flow detection device that supports remote control of valve opening utilizes a cross-section adjustment component. Through the setting of a sealing cone and a sealing ring, the cross-section size of the device can be adjusted. When the gas flow inside the pipeline is extremely low, the cross-sectional area of ​​the pipeline is reduced, thereby increasing the flow rate. This facilitates the sensor to measure the flow rate in the pipeline. In addition, it adopts manual control by rotating a handle, which is convenient, accurate, and easy to operate.

[0017] 2. This gas flow detection device, which supports remote control of valve opening, utilizes auxiliary components and a display metering plate, along with a threaded sleeve with an observation groove on its surface, to enable operators to quickly and accurately obtain relevant data during device control, making it convenient to use.

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides two technical solutions:

[0025] Example 1: A gas flow detection device supporting remote control of valve opening, comprising:

[0026] Operating pipeline 1 is equipped with a remote on / off valve 2, valve model VQZ235R or other valves of the same type. The left side of operating pipeline 1 is connected to a detection bend 3. A sealing ring 4 is fixedly connected to the inner wall of the detection bend 3. The sealing ring 4 and the sealing cone 635 are mutually compatible. One end of the detection bend 3 is connected to a flow detection body 5, model Bronkhorst EL-FLOW Select F-110C or other products of the same type.

[0027] The cross-section adjustment component 6 is located on the surface of the detection bend 3. The cross-section adjustment component 6 is used to adjust the cross-section of the gas flow to make the flow rate more accurate.

[0028] Auxiliary component 7 is fixedly connected to the surface of cross-section adjustment component 6 on one side. Auxiliary component 7 is used to assist in the detection and adjustment process, so that the workers can observe and the device can operate smoothly. By using the cross-section adjustment component 6, through the setting of sealing cone block 635 and sealing ring 4, the cross-section size of the device can be adjusted. When the gas flow rate inside the pipeline is extremely low, the cross-sectional area of ​​the pipeline is reduced, thereby increasing the flow rate and making it easier for the sensor to measure the flow rate in the pipeline. In addition, the manual control is achieved by rotating handle 636, which is convenient, accurate and easy to operate.

[0029] Example 2 differs from Example 1 primarily in that: a gas flow detection device supporting remote control of valve opening, the cross-section adjustment assembly 6 includes a support base 61 fixedly connected to the surface of the detection bend 3, a sealing plate 62 fixedly connected to the top of the support base 61, an operating unit 63 fixedly connected to the top of the sealing plate 62, the operating unit 63 including a threaded sleeve 631 fixedly connected to the top of the sealing plate 62, an observation groove 637 formed on the surface of the threaded sleeve 631, a screw 632 passing through the interior of the threaded sleeve 631, a handle 636 fixedly connected to the top of the screw 632, an indicator block 633 rotatably connected to the bottom of the screw 632, and a connecting rod 634 fixedly connected to the bottom of the indicator block 633. The bottom end of the connecting rod 634 passes through the detection bend 3 and extends into the interior of the detection bend 3. A sealing cone 635 is fixedly connected to the bottom end of the connecting rod 634. A silicone sealing gasket is provided on the surface of the sealing cone 635. The auxiliary component 7 includes a display measuring plate 71 fixedly connected to the top left side of the sealing plate 62. A limiting plate 72 is fixedly connected to the top right side of the sealing plate 62. One side of the limiting plate 72 is polished smooth and fits tightly against the other side of the limiting plate 72. The two contact surfaces slide relative to each other. By using the auxiliary component 7 and the display measuring plate 71, and in conjunction with the threaded sleeve 631 with an observation groove 637 on its surface, the relevant data can be quickly and accurately obtained by the operator during the control of the detection device, making it convenient to use.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] During operation, the flow rate is detected by the flow detection body 5. If necessary, the entire pipeline of the operating pipeline 1 is opened and closed by the remote opening and closing valve 2. When the flow rate is extremely low, in order to ensure that the flow detection body 5 can detect it with high precision, the handle 636 is rotated, which directly drives the screw 632 to move down along the threaded sleeve 631, and at the same time drives the indicator block 633 to move down. One side of the indicator block 633 slides directly relative to the limit plate 72, and the other side of the indicator block 633 indicates the display metering plate 71. At the same time, the connecting rod 634 drives the sealing cone block 635 to move down. The sealing cone block 635 contacts the sealing ring 4 until it seals. The cross-sectional area between the sealing cone block 635 and the sealing ring 4 changes continuously. The operator reads and records the relative height between the indicator block 633 and the display metering plate 71 through the observation slot 637, and reads and records the flow velocity on the surface of the flow detection body 5. According to the necessary flow conversion formula, the relevant data is converted with the data read by the flow detection body 5. When the device is finished using it, it is restored.
