Description

Technical Field

[0001] The present invention relates to the technical field of automated solenoid valves, and in particular to an automated solenoid valve with air pressure detection and abnormal alarm functions. Background Art

[0002] Automatic solenoid valves can automatically respond to electrical signals to control the flow and closing of fluids without manual intervention. They have high control accuracy and fast response speed. Therefore, automatic solenoid valves are widely used in various industries. When automatic solenoid valves are used to transport gas, they usually need to detect the gas pressure to ensure the safety of the automatic solenoid valves when in use. The patent name disclosed in the prior art with application number "CN202310553024.9" is "Automated solenoid valve with dual power-off warning structure", which discloses the setting of an electrochromic film as an alternative warning structure. For example, when the internal power of a button battery is exhausted and the solenoid valve is powered off, there is no first-time warning from a buzzer, and the current solenoid valve responsible person may need some time to find out that the solenoid valve is powered off before giving a telephone feedback. By setting an electrochromic film, the buzzer can be replaced to achieve the first-time warning. Warning, because the electrochromic film and the solenoid valve are set in the same power circuit, after the solenoid valve is powered on, the electrochromic film will change color due to its own characteristics. When the staff conducts inspections, they can confirm whether the solenoid valve is powered on normally by observing the color of the electrochromic film. When the solenoid valve is powered off, the electrochromic film will also be powered off, and the electrochromic film will restore to its original color. Therefore, when the staff finds that the electrochromic film has changed during inspections, they can immediately know that the solenoid valve is powered off, and then perform the corresponding equipment shutdown operation; The patent titled "A Solenoid Valve with Leakage Detection Function" disclosed in the prior art with application number "CN202323190157.9" discloses that the air pressure inside the intake pipe is detected by an intake air pressure sensor, and the air pressure inside the outlet pipe is detected by an outlet air pressure sensor, and the detection signal is transmitted to the controller, which receives it. If the air pressures of the two are different, it indicates that there is a leak. When the air pressure inside the intake pipe is higher than the air pressure of the outlet pipe, it indicates that there is a leak at the outlet pipe. Otherwise, it indicates that there is a leak at the intake pipe. When the controller processes the signal and finds that there is a gas leak, it controls the first electric valve and the second electric valve. The electric valve is closed, thereby realizing the cutting off of the solenoid valve body. At the same time, the gas concentration sensor and the gas outlet detector detect the gas concentration on the left and right sides respectively, and send the signal to the controller. When it detects that the gas concentration changes, the controller controls the alarm to sound an alarm, and the solenoid valve body is protected by the protective frame and the arc frame. At the same time, the solenoid valve body can be cooled by the fan. The dust at the air inlet can be filtered by the first filter plate, and the dust at the vent can be filtered by the second filter plate. When the second filter plate needs to be cleaned, the protective frame is removed and the second filter plate is pulled out downwards. When the solenoid valve mentioned above is in use, the detection ends of the internal intake air pressure sensor and the outlet air pressure sensor are in direct contact with the gas in the solenoid. Since the diameters of the detection ends of the intake air pressure sensor and the outlet air pressure sensor are small, and the gas flow in the pipeline of the solenoid valve may present a complex velocity and pressure distribution, the intake air pressure sensor and the outlet air pressure sensor can only detect the air pressure in a small surrounding range, and cannot detect the air pressure near the pipeline wall. Therefore, the intake air pressure sensor and the outlet air pressure sensor cannot reflect the air pressure conditions of the entire pipeline cross section, affecting the accuracy of the air pressure detection results. Since the accuracy of the air pressure detection results is low, it will also affect the accuracy of the later abnormal situation alarm, so that the automatic solenoid valve cannot accurately detect the air pressure and accurately alarm for abnormal situations; Therefore, we proposed an automated solenoid valve with air pressure detection and abnormal alarm functions to solve the above problems. Summary of the invention

Therefore, the air inlet pressure sensor and the air outlet pressure sensor cannot reflect the air pressure conditions of the entire pipeline cross section, affecting the accuracy of the air pressure detection results. Due to the low accuracy of the air pressure detection results, it will also affect the accuracy of the subsequent abnormal situation alarm, so that the automated solenoid valve cannot accurately detect the air pressure and accurately alarm for abnormal situations.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the automatic solenoid valve with air pressure detection and abnormal alarm functions can collect the pressure of gas in a larger area through the other end of the main air collecting hood with a funnel-shaped structure, so that the pressure sensor can detect the air pressure in a larger range around it, thereby improving the accuracy of the pressure sensor in air pressure detection, so that the automatic solenoid valve can accurately detect the air pressure and accurately alarm for abnormal situations. The specific contents are as follows: By making one end of the main gas collecting hood fit in contact with the detection end of the pressure sensor, the other end of the main gas collecting hood with a funnel-shaped structure can collect the pressure of the gas in a larger area, so that the pressure sensor can detect the air pressure in a larger range around it, and the pressure sensor can detect the air pressure near the pipe wall, and then the pressure sensor can detect more accurate air pressure data, thereby improving the accuracy of the pressure sensor in air pressure detection, and then facilitating the central processing module to analyze the air pressure data in the later stage.

If the gas flow in the pipeline forms turbulence, the main gas collecting hood can help smooth the fluid flow and reduce the impact of turbulence on the pressure sensor measurement, thereby further improving the accuracy of the pressure sensor in detecting air pressure; Furthermore, the gas push rod is pushed by the gas, so that the gas push rod pulls the six groups of connecting ropes, and then the connecting ropes can drive the six groups of deployment columns to rotate outward, so that the deployment columns drive the auxiliary gas collecting hood made of umbrella cloth material to expand outward, and then the diameter of the auxiliary gas collecting hood becomes larger. Therefore, through the cooperation of the auxiliary gas collecting hood and the main gas collecting hood, the range of the gas collecting area of ​​the auxiliary gas collecting hood can be further increased, so that the pressure sensor can detect the air pressure of a larger range of surrounding gases, thereby further improving the accuracy of the pressure sensor in detecting air pressure; The gas in the main gas hood can be discharged into the valve seat body through the exhaust hole in the mirror "L" shape structure, which will not affect the gas pressure detection and the gas transportation work; When the moving iron core and the valve core rise, the moving iron core pulls the control rope, which in turn causes the control rope to drive the control rod to rotate, thereby causing the control rod to drive the control plate to rotate, so that the valve port is tilted, and then the gas flows to the right through the valve port, preventing the gas from directly blowing vertically to the valve core, thereby protecting the valve core and preventing the valve core from being subjected to a large impact force of the gas; When the control plate rotates, it pulls the connecting cloth made of umbrella cloth with a larger height area reserved, so that the connecting cloth with a circular ring structure can perform a sealing operation between the control plate and the opening, so that the gas can only be discharged through the valve port; The limit block can be used to limit the control plate so that the control plate can only rotate clockwise and cannot rotate counterclockwise.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 14 , the present invention provides the following technical solutions: Embodiment 1: The automated solenoid valve with air pressure detection and abnormal alarm functions in this embodiment, when in use, due to the small diameter of the detection end of the pressure sensor 101, the gas flow in the pipeline of the automated solenoid valve may present a complex velocity and pressure distribution, and then the pressure sensor 101 can only detect the air pressure in a small surrounding range. Therefore, the pressure sensor 101 cannot reflect the air pressure conditions of the entire pipeline cross section, affecting the accuracy of the air pressure detection result. Therefore, the automated solenoid valve cannot accurately detect the air pressure and accurately alarm for abnormal conditions. In order to solve this problem, this embodiment discloses the following technical contents, and specific reference is made to the attached Figure 1-Figure 7As shown, it includes an upper shell 1, and a connecting shell 2 installed through the upper shell 1; a coil 13 is installed in the space between the upper outer side of the connecting shell 2 and the interior of the upper shell 1; a valve seat body 3 is installed below the connecting shell 2, an inlet connection end 4 connected to the external air inlet pipe is installed at the left end of the valve seat body 3, and an outlet connection end 5 connected to the external air outlet pipe is installed at the right end of the valve seat body 3; a fixed iron core 14 is installed inside the upper part of the connecting shell 2, and a fixed iron core 14 is installed inside the lower part of the connecting shell 2. There is a moving iron core 7, and a valve core 71 is installed below the moving iron core 7. The bottom of the moving iron core 7 and the valve core 71 are both inserted into the valve seat body 3. The top of the moving iron core 7 is connected to the bottom of the fixed iron core 14 through a connecting spring 72. An alarm 9 is installed on the upper left side of the valve seat body 3. A fixing plate 8 is installed inside the valve seat body 3. A regulating plate 11 is installed inside the fixing plate 8 through a mounting assembly. A valve port 115 for gas circulation is opened in the middle of the regulating plate 11, and the valve core 71 is connected to the valve port 115 in a concave-convex manner.

[0019] A detection component 10 is installed inside the left side of the valve seat body 3 through a bracket, and a pressure sensor 101 is installed inside the detection component 10. The detection end on the left side of the pressure sensor 101 is connected to the main air collecting hood 6. The outer side of the fixed plate 8 is in contact with the inner wall of the valve seat body 3. The fixed plate 8 is arranged in a "Z" shape. A through hole 81 is opened in the horizontal part of the fixed plate 8; the installation component includes a sealing ring installed in the through hole 81, and a regulating plate 11 is installed in the through hole 81 through a sealing ring and a screw. A ring-shaped structure is installed on the side of the detection component 10 close to the main air collecting hood 6 The sealing plate 102 has a structure, and the right side of the main gas collecting hood 6 is penetrated inside the sealing plate 102. Two limiting columns 61 are symmetrically installed on the outer side of the right side surface of the main gas collecting hood 6. The limiting columns 61 are arranged in the detection component 10. The left side of the main gas collecting hood 6 is arranged in a funnel-shaped structure, and the right side of the main gas collecting hood 6 is arranged in a solid structure. Exhaust holes 62 for gas discharge are evenly spaced inside the right side of the main gas collecting hood 6. The exhaust holes 62 are arranged in a mirrored "L" shape structure. The exhaust holes 62 are arranged on the left side of the sealing plate 102, and the diameter of the left side of the main gas collecting hood 6 is larger than the diameter of the right side of the main gas collecting hood 6.

[0020] First, connect the inlet connection end 4 to the external air intake pipe, and then connect the outlet connection end 5 to the external air outlet pipe, and then the controller in the automatic solenoid valve automatically controls the coil 13 to be energized. At this time, the coil 13 cooperates with the fixed iron core 14 to absorb the moving iron core 7 upward through electromagnetic force, and the moving iron core 7 drives the valve core 71 to move upward. At this time, the connecting spring 72 is squeezed and stored, and the valve core 71 moves upward and separates from the valve port 115. At this time, the gas in the inlet connection end 4 can flow to the outlet connection end 5 through the valve port 115. After using it for a period of time, the coil 13 is powered off. At this time, the moving iron core 7 is automatically driven downward by the stored force of the connecting spring 72. At this time, the moving iron core 7 drives the valve core 71 to move downward together, so that the valve core 71 is inserted into the valve port 115, and the valve port 115 is sealed and blocked, thereby stopping the flow of gas. Therefore, the solenoid valve can be automatically opened and closed, which is convenient to meet different usage requirements.

[0021] When the gas in the inlet connection end 4 flows to the outlet connection end 5 through the valve port 115, most of the gas in the inlet connection end 4 first enters the left side of the main gas collecting hood 6 in the left end of the valve seat body 3. Since the left side of the main gas collecting hood 6 is a funnel-shaped structure, the left side of the main gas collecting hood 6 can collect gas from a larger area in the left end of the valve seat body 3. At this time, the gas collected in the larger area applies a rightward pressure to the main gas collecting hood 6, so that the right end of the main gas collecting hood 6 applies a pressure to the detection end of the pressure sensor 101 in the detection component 10. At this time, the pressure sensor 101 can detect the air pressure of the surrounding gas in a larger range, so that the pressure sensor 1 01 detects more accurate air pressure data, and then the pressure sensor 101 converts the air pressure into an electrical signal, and then the central processing module reads and analyzes the electrical signal, and compares the current air pressure value detected by the pressure sensor 101 with the set air pressure value. After analysis, if the current air pressure value detected by the pressure sensor 101 is greater than or less than the set air pressure value, the central processing module controls the alarm 9 to sound an alarm, and then the staff comes to deal with the abnormal situation in time to check whether the gas leakage is caused by a seal failure, or other failures, etc., so that the automatic solenoid valve has air pressure detection and abnormal alarm functions, which improves the safety of the automatic solenoid valve when in use.

[0022] At the same time, the gas in the main gas collecting hood 6 is later discharged into the valve seat body 3 through the exhaust hole 62 with a mirror image "L" shape structure, so that the gas can flow well into the outlet connection end 5 later.

[0023] At the same time, when the automatic solenoid valve is in use, the pressure sensor 101 is placed and protected by the detection component 10 with a hollow interior and a cylindrical shape to prevent the pressure sensor 101 from being exposed to the outside, and the right end of the main air collecting hood 6 is in close contact with the detection end of the pressure sensor 101, and the sealing plate 102 is in close contact with the outer side of the right end of the main air collecting hood 6, so that the pressure sensor 101 can be protected to prevent impurities in the valve seat body 3 from affecting the use of the pressure sensor 101, thereby improving the service life of the pressure sensor 101. At the same time, the use of the main air collecting hood 6 can smooth the flow of turbulent gas in the valve seat body 3 and reduce the impact of turbulence on the detection of the pressure sensor 101, thereby improving the accuracy of the pressure sensor 101 in detecting air pressure. At the same time, the sealing plate 102 blocks the limiting column 61 to prevent the main air collecting hood 6 from separating from the pressure sensor 101 and affecting the air pressure detection work, so that the main air collecting hood 6 is always in close contact with the detection end of the pressure sensor 101.

[0024] Embodiment 2: The automatic solenoid valve with air pressure detection and abnormal alarm function in this embodiment can further improve the accuracy of air pressure detection on the basis of embodiment 1, so that the automatic solenoid valve can further accurately detect air pressure and accurately alarm abnormal situations. The specific structure is as follows, refer to the attached Figure 4-Figure 9 As shown, an auxiliary air collecting hood 12 is installed on the left side of the main air collecting hood 6. The auxiliary air collecting hood 12 is arranged in a funnel-shaped structure. The interior of the auxiliary air collecting hood 12 is arranged in a hollow structure. The diameter of the right side of the auxiliary air collecting hood 12 is equal to the diameter of the left side of the main air collecting hood 6. The diameter of the right side of the auxiliary air collecting hood 12 is greater than the diameter of the left side of the auxiliary air collecting hood 12. The left side of the main air collecting hood 6 is grooved with rotating rods 152 at equal intervals. The outer side of the rotating rod 152 is penetrated and installed with an expansion column 15. The expansion column 15 is relative to the outer side of the auxiliary air collecting hood 12. The outer side of one end of the rotating rod 152 is wrapped with a connecting rope 151, and the outer side of the other end of the rotating rod 152 is nested with a second vortex spring 153. The interior of the main air collecting hood 6 is slidably connected with a gas push rod 16 in a "T" shape. The right end of the gas push rod 16 is connected to the interior of the main air collecting hood 6 through a return spring 161. The other end of the connecting rope 151 is installed at equal intervals on the outer side of the gas push rod 16. The deployment column 15 forms a rotating structure with the main air collecting hood 6 through the gas push rod 16.

[0025] When the gas in the inlet connection end 4 flows to the outlet connection end 5 through the valve port 115, most of the gas in the inlet connection end 4 first enters the auxiliary gas collecting hood 12 in the left end of the valve seat body 3 and the left side of the main gas collecting hood 6. At this time, the gas will push the gas push rod 16 in a "T" shape on the left side of the main gas collecting hood 6. At this time, the reset spring 161 accumulates force, and then the gas push rod 16 pulls the six groups of connecting ropes 151 at the same time. At this time, the other end of the connecting rope 151 drives the wound and connected rotating rod 152 to rotate, and the rotating rod 152 drives the unfolding column 15 to rotate when it rotates. At this time, the second vortex spring 153 accumulates force, and the unfolding column 15 rotates to expand the auxiliary gas collecting hood 12 made of umbrella cloth outward, thereby increasing the diameter of the auxiliary gas collecting hood 12, and then the auxiliary gas collecting hood 12 can collect gas in a larger area, so that the pressure sensor 101 can detect the air pressure in a larger range around it, thereby further improving the accuracy of the pressure sensor 101 in detecting air pressure.

[0026] Embodiment 3: The automatic solenoid valve with air pressure detection and abnormal alarm function in this embodiment can reduce the impact force of gas on the valve core 71 on the basis of embodiment 1 when in use, can protect the valve core 71, and increase the service life of the valve core 71. The specific structure is as follows, refer to the attached Figure 10-Figure 14 As shown, the installation component includes a connecting cloth 17 with a circular ring structure installed in the through opening 81. The connecting cloth 17 is made of umbrella cloth material. A regulating plate 11 is installed in the connecting cloth 17. The front and rear sides of the regulating plate 11 are connected to the inner wall of the through opening 81 through a regulating rod 112. A first vortex spring 113 is sleeved on the outer side of the regulating rod 112 on the front side of the regulating plate 11. A control rope 114 is wound around the outer side of the regulating rod 112 on the rear side of the regulating plate 11. A connecting cloth 17 is arranged below the regulating rod 112. The upper end of the control rope 114 is connected to the rear side of the moving iron core 7 through a guide wheel assembly. The regulating plate 11 forms a rotating structure with the through opening 81 through the control rope 114; limit blocks 111 with a fan-shaped structure are installed on the upper left side and the lower right side of the regulating plate 11. The distance between the two limit blocks 111 is greater than the diameter of the through opening 81. The limit block 111 on the lower right side of the regulating plate 11 is arranged below the connecting cloth 17.

[0027] When the movable iron core 7 drives the valve core 71 to move upward, the movable iron core 7 pulls the control rope 114, and the control rope 114 drives the control rod 112 connected to the lower end to rotate. At this time, the control rod 112 drives the first vortex spring 113 to store force, and the control rod 112 drives the control plate 11 to rotate, so that the control plate 11 is inclined. At the same time, when the control plate 11 rotates, the connecting cloth 17 of the material of the umbrella cloth reserved for a certain height on the lower outer side is pulled. Since the connecting cloth 17 is arranged in a circular ring shape, the connecting cloth 17 can well seal the control plate 11 and the through port 81, so that the gas can flow out of the valve port 115 well. Since the control plate 11 is inclined, the control plate 11 drives the valve port 115 to be inclined as well, and then the valve port 115 discharges the gas to the right side, so as to avoid the gas being discharged vertically upward and generating a large impact force on the valve core 71 above, thereby protecting the valve core 71 well and improving the service life of the valve core 71.

[0028] By installing limit blocks 111 on the upper left side and the lower right side of the regulating plate 11, the limit blocks 111 can limit the regulating plate 11 for protection. The regulating plate 11 rotates counterclockwise when impacted, thereby ensuring the stability of the regulating plate 11 when in use, thereby completing a series of tasks.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
