Description

Technical Field

[0001] This utility model relates to the field of wastewater pipeline technology, specifically to a water-flowing, air-resistance-controlled, venting pipeline. Background Technology

[0002] Air resistance refers to the resistance encountered by a fluid (gas or liquid) when moving through a pipe. In industrial pipelines, air resistance typically arises from friction between the fluid and the pipe wall, bends, valves, reductions in diameter, and the influence of the surrounding environment. Air resistance not only affects the flow velocity and flow rate of the fluid within the pipe but also generates additional energy consumption and operating costs during normal operation. To eliminate air resistance, venting pipes can be installed. For example, Chinese Patent 202120937220.2 discloses a liquid pipeline air resistance elimination device, including an exhaust pipe. The exhaust pipe is positioned on a horizontal section connecting to both ends of a downward bend in the liquid pipe, and the connection point between the exhaust pipe and the liquid pipe is located at the upper part of the liquid pipe.

[0003] The existing technology has the following problems: the exhaust pipe is connected to the atmosphere, which can continuously discharge gas, but the pressure in the system fluctuates frequently. Especially during the exhaust process, the pressure at the exhaust port may be lower than the atmospheric pressure, which will attract outside air in, causing more gas to enter the system and forming a vicious cycle. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a water-flow gas-resistance venting pipe to solve the technical problem that in the prior art, the continuous discharge of gas from the venting pipe may cause the pressure at the exhaust port to be lower than atmospheric pressure, thereby attracting outside air in and causing more gas to enter the system.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a water-flowing, air-resistance-controlled venting pipe, comprising:

[0007] The connecting pipe has flanges at both ends for pipe connection;

[0008] An vent pipe, which is vertically and upwardly connected to the connecting pipe via a connector; and

[0009] The exhaust control assembly includes a solenoid valve, a controller, and a flow rate sensor. The flow rate sensor is installed inside the connecting pipe to detect the water flow rate. The solenoid valve is installed at the top of the exhaust pipe. Both the flow rate sensor and the solenoid valve are electrically connected to the controller. The controller is used to control the opening of the solenoid valve to exhaust water based on the water flow rate detected by the flow rate sensor.

[0010] In some embodiments, a water spray prevention component is also included, which is installed inside the drain pipe to block liquid spray.

[0011] In some embodiments, the anti-spray assembly includes an anti-spray net, which is built into the drain pipe.

[0012] In some embodiments, the anti-spray assembly further includes a float and a closing frame. The anti-spray net has a groove, the float is inserted into the groove, and the closing frame is arranged above the float and fixed to the inner wall of the drain pipe. The inner diameter of the closing frame matches the outer diameter of the float and is used to fit and seal with the float when it floats up.

[0013] In some embodiments, a plurality of circumferentially arranged guide rods are connected between the anti-spray net and the closed frame, and the float is slidably connected between the plurality of guide rods.

[0014] In some embodiments, the connector includes a bendable pipe and a fixing member. The two ends of the bendable pipe are respectively connected to the connecting pipe and the drain pipe. One end of the fixing member is connected to the drain pipe, and the other end is detachably connected to the connecting pipe, for fixing the bending curvature of the bendable pipe and the orientation of the drain pipe.

[0015] In some embodiments, the bendable pipe is a corrugated pipe.

[0016] In some embodiments, the fastener includes a binding strap and a screw, and the outer side of the connecting tube is provided with a stud protrusion. One end of the binding strap is connected to the drain pipe, and the other end is connected to the screw, and the screw is detachably connected to the stud protrusion.

[0017] In some embodiments, the insert protrusion is annular in shape and coaxially arranged with the connecting tube.

[0018] In some embodiments, the number of the stud protrusions is two, and they are placed on both sides of the drain pipe.

[0019] Compared with the prior art, the water-flow air resistance venting pipe provided by this utility model is installed on the water-flowing pipeline through a connecting pipe. In conjunction with the venting pipe and exhaust control components, when air resistance is generated and the flow rate is significantly reduced, the venting pipe is opened to exhaust air. At normal flow rate, the venting pipe passage is cut off, forming intermittent gas discharge, which avoids the possible attraction of outside air under frequent pressure fluctuations in the system.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To address the technical problem that continuous gas discharge from the venting pipe may cause the pressure at the exhaust port to drop below atmospheric pressure, thereby attracting outside air and resulting in more gas entering the system, this invention provides a water-flow gas-resistance venting pipe that can intermittently open the venting pipe according to the wastewater flow rate, avoiding the frequent fluctuations in wastewater flow pressure and the intake of outside air when no gas resistance is generated.

[0031] It should be noted that the water-flowing air-resistance venting pipe described in this utility model is used in, but not limited to, wastewater pipes. For ease of explanation, this utility model only uses the application of the water-flowing air-resistance venting pipe in wastewater pipes as an example. The principle of the water-flowing air-resistance venting pipe in other types of equipment is essentially the same as that in wastewater pipes, and will not be elaborated here.

[0032] Please see Figure 1-3This utility model provides a water-cooled airlock venting pipe, which includes a connecting pipe 1, a venting pipe 2, and an exhaust control component 3. Both ends of the connecting pipe 1 are equipped with flanges 101 for pipe connection. The water-cooled airlock venting pipe is installed into a pipe prone to airlock through the flanges 101, and both ends are connected to the wastewater pipe within the system. The venting pipe 2 is vertically connected to the connecting pipe 1 via a connector 5. The venting pipe 2, connected to the pipe prone to airlock, discharges the accumulated gas in the pipe, allowing the gas to escape naturally. The flow is improved to reduce or even eliminate air resistance. To achieve intermittent venting, the venting control assembly 3 includes a solenoid valve 31, a controller 32, and a flow rate sensor 33. The flow rate sensor 33 is installed inside the connecting pipe 1 to detect the water flow rate. The solenoid valve 31 is installed at the top of the venting pipe 2. Both the flow rate sensor 33 and the solenoid valve 31 are electrically connected to the controller 32. The controller 32 controls the opening of the solenoid valve 31 to vent based on the water flow rate detected by the flow rate sensor 33. If the wastewater flow rate through the connecting pipe 1 is significantly lower than expected, the solenoid valve 31 is opened to vent until the flow rate returns to the expected range. Air resistance may cause the fluid flow to become unstable. If pulsating or intermittent flow occurs, the solenoid valve 31 can also be opened to vent. In the case of pulsating or intermittent flow, if opening the solenoid valve 31 does not improve the stability of the flow rate within a specified time, the solenoid valve 31 is closed to prevent fluctuations from causing negative pressure and introducing outside air.

[0033] In one embodiment, please refer to Figure 2 To prevent liquid spraying during exhaust, a water spray prevention component 4 is also included. The water spray prevention component 4 is installed inside the exhaust pipe 2 to block liquid spraying.

[0034] Specifically, the anti-spray assembly 4 includes an anti-spray net 41, which is built into the drain pipe 2. The anti-spray net 41 allows gas to pass through its mesh and has a certain blocking effect on the sprayed liquid, thus forming a preliminary anti-spray effect.

[0035] Furthermore, to prevent overflowing liquid from spraying out, the anti-spray assembly 4 also includes a float 42 and a closing frame 43. The anti-spray net 41 has a groove 4101, the depth of which is less than the radius of the float 42. The float 42 is inserted into the groove 4101. The closing frame 43 is arranged above the float 42 and fixed to the inner wall of the drain pipe 2. The inner diameter of the closing frame 43 matches the outer diameter of the float 42, so that it can be inserted and sealed when the float 42 floats up. When the liquid overflows onto the anti-spray net 41, it will cause the float 42 to float up. When the float 42 floats up to the closing frame 43, it fits into the inner hollow opening of the closing frame 43 to form a seal, thereby blocking the channel and preventing the liquid from continuing to flow upward, thus forming an anti-spray effect.

[0036] Furthermore, in order to provide sufficient gas flow space within the vent pipe 2 and to guide the rise and fall of the float 42, the diameter of the anti-spray net 41 is larger than the diameter of the float 42, providing a sufficiently large air flow space. Multiple circumferentially arranged guide rods 44 are connected between the anti-spray net 41 and the closed frame 43. The float 42 is slidably connected between the multiple guide rods 44, with at least three guide rods 44. The float 42 is located within the circular area enclosed by the multiple guide rods 44, and the rise and fall of the float 42 are guided by the guide rods 44, improving the stability of its buoyancy and descent.

[0037] In one embodiment, please refer to Figure 1 and Figure 3 To accommodate the installation of water flow and air resistance drainage pipes with different orientations and inclinations, the connector 5 includes a bendable pipe 51 and a fixing member 52. The two ends of the bendable pipe 51 are connected to the connecting pipe 1 and the drainage pipe 2, respectively. One end of the fixing member 52 is connected to the drainage pipe 2, and the other end is detachably connected to the connecting pipe 1. It is used to fix the bending curvature of the bendable pipe 51 and the orientation of the drainage pipe 2. The angle between the drainage pipe 2 and the connecting pipe 1 is adjusted by the bendable pipe 51. The connecting pipe 1 is coaxial with the water flow pipe, while the drainage pipe 2 needs to be perpendicular to the horizontal plane and facing upwards to obtain a better drainage angle and reduce the probability of liquid spraying. After adjusting to the corresponding angle, the angle between the drainage pipe 2 and the connector 5 is positioned by the fixing member 52.

[0038] Furthermore, the bendable pipe 51 is a corrugated pipe, which has the effect of being bendable and adjustable.

[0039] Understandably, depending on the application and material properties, flexible pipe fittings 51 can also be made of hoses, spring sheaths, metal braided pipes, or other pipe fittings with bendable properties, and are not limited to these in this study.

[0040] Furthermore, in order to position the bending angle, the fastener 52 includes a binding strap 521 and a screw 522. The outer side of the connecting pipe 1 is provided with a stud protrusion 523, which is a part protruding from the connecting pipe 1 to prevent the screw 522 from drilling through the connecting pipe 1. One end of the binding strap 521 is connected to the drain pipe 2, and the other end is connected to the screw 522. The screw 522 is detachably connected to the stud protrusion 523. In use, the bendable pipe 51 is bent to the required angle between the drain pipe 2 and the connecting pipe 1, and then the binding strap 521 is nailed to the stud protrusion 523 by the screw 522 to position the position. There are multiple binding straps 521, and the number is based on achieving the positioning effect.

[0041] Furthermore, to facilitate the installation of screws 522 at angular positions, the embedded protrusion 523 is annular in shape and coaxially arranged with the connecting tube 1.

[0042] Furthermore, there are two embedded protrusions 523, which are placed on both sides of the drain pipe 2 to facilitate the support and positioning of multiple binding straps 521 on both sides, so as to achieve a better fixing effect.

[0043] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail as follows: The connecting pipe 1 is coaxially installed on the pipeline where air resistance is easily generated during wastewater flow, and the flexible pipe fitting 51 is bent. The drain pipe 2 is perpendicular to the horizontal plane and then positioned by the fixing parts 52, namely the binding strap and screws 522. When air resistance occurs, the flow rate sensor 33 detects a significant decrease in flow rate. The controller 32 controls the solenoid valve 31 to open according to the detected flow rate signal to vent the air. When the flow rate recovers, the solenoid valve 31 is closed to form intermittent venting. When a small amount of liquid spray occurs, the anti-spray net 41 and the higher opening of the drain pipe 2 can play a blocking role. When liquid overflow occurs, the float ball 42 will float and close the closing frame 43 to seal, forming a blocking effect for liquid to spray outward.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
