Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of alarm devices, and particularly relates to a valve leakage intelligent alarm device based on a built-in sensor. BACKGROUND

[0002] In the fields of industrial production, energy transportation, chemical storage and transportation, etc., as a key component of a fluid control system, a valve is prone to leakage at a connecting part with a pipe flange due to long-term bearing of medium pressure, temperature change and vibration and other factors. Valve leakage not only causes medium waste and production efficiency reduction, but also may cause fire, explosion, environmental pollution or personnel poisoning and other serious safety accidents due to leakage medium (such as flammable and explosive gas, corrosive liquid, etc.), so timely monitoring and early warning of valve leakage are very important.

[0003] At present, existing valve leakage monitoring devices mostly use a single sensor for detection, and have problems of limited detection dimension, easy environmental interference, high false negative and false positive rates, and especially difficult to identify early micro leakage; at the same time, most devices only have a single alarm function and rely on an external power supply system, and once power failure or electronic component failure occurs, the alarm may fail, delaying the processing opportunity.

[0004] In addition, the traditional device lacks an effective treatment mechanism for the leakage medium: when the leakage amount is large, direct overflow of the leakage medium not only pollutes the environment, but also may cause the monitoring device itself to be damaged due to pressure accumulation, reducing the service life of the equipment.

[0016] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:

[0017] 1. The left clamp body of this invention integrates three sensors: humidity, gas, and ultrasound. It can capture leakage signals from multiple dimensions such as humidity changes, leakage gas composition, and micro-vibration sound waves. Compared with single sensor detection, it significantly reduces the probability of missed detection and false detection. In particular, it can identify early micro-leakage. The detection component is specially fitted at the connection between valve flange and pipe flange (high-risk leakage location), and a closed space is formed by sealing strips to ensure that the sensor only detects key leakage points, avoids external environmental interference, and improves detection accuracy.

[0018] 2. This invention can release pressure in a timely manner when the pressure in the enclosed space is too high through the pressure relief valve of the right clamp body. Combined with the phased storage design of the protection and recovery component (the medium flow direction is controlled by pressure sensors and solenoid valves), it can effectively prevent the detection component from being damaged by excessive leakage medium and excessive pressure, thus extending the service life of the equipment.

[0019] 3. The protection and recycling component of this invention achieves orderly storage through pipes and solenoid valves, and with the help of one-way valves to prevent media backflow, it can not only avoid the direct discharge of leaked media causing environmental pollution or safety hazards (such as flammable, explosive, or corrosive media), but also facilitate centralized processing in the later stage, which meets the requirements of safety and environmental protection.

[0020] 4. The dual warning component of the present invention converts the potential energy of the leaked medium into electrical energy through the transmission blades and kinetic energy generator to power the second warning light, without the need for additional energy consumption, which is in line with the concept of energy conservation.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0033] like Figures 1-10 As shown, the present invention proposes an intelligent valve leakage alarm device based on a built-in sensor, which mainly consists of three parts: a detection component 1, a protection and recovery component 2, and a dual warning component 3. The detection component 1 includes a left clamp body 10 and a right clamp body 11, which are connected by a movable structure to form an openable and closable clamp design, used to fit and fix the flange of the valve to be monitored and the flange connection of the pipeline. The protection and recovery component 2 is used to prevent the detection component 1 from being damaged due to excessive leakage medium, and at the same time collects and safely stores the leakage medium. The dual warning component 3 recovers the potential energy generated by the leakage and triggers a secondary alarm.

[0034] The top of the left clamp body 10 is provided with three sensor mounting chambers 100, which respectively house a humidity sensor 103, a gas sensor 104 and an ultrasonic sensor 108. The probes of the three sensors all face the inside of the clamp, and are used to detect the humidity changes, leakage gas composition and ultrasonic vibration signals (sound waves generated by tiny leaks) on the valve surface in real time.

[0035] The bottom of the sensor mounting chamber 100 is connected to a four-way conduit 102, one end of which extends to the main board mounting chamber 101 on the left side of the clamp body 10. The sensor's connecting wire passes through the four-way conduit 102 into the main board mounting chamber 101 and is electrically connected to the built-in control main board to realize the transmission of detection signals.

[0036] The top of the left clamp body 10 is also equipped with an alarm light 109, which is electrically connected to the control board. When the sensor detects a leakage signal, the control board triggers the alarm light 109 to flash.

[0037] The tail of the left clamp body 10 is fixed with a mounting plate 106, and a horizontal shaft 107 is welded on the mounting plate 106; the front end is integrally formed with a U-shaped fixing plate 105, which is used to cooperate and fix with the front end structure of the right clamp body 11. In addition, sealing strips 4 are embedded on the mating end surfaces of the left clamp body 10 and the right clamp body 11 to ensure that a closed space is formed after clamping, so as to avoid leakage of the medium and affect the detection accuracy.

[0038] C-shaped blocks 111 are welded to both the tail and front of the right clamp body 11. The C-shaped blocks 111 at the tail are sleeved on the shaft 107 at the tail of the left clamp body 10, so that the right clamp body 11 can rotate around the shaft 107 to realize the opening and closing action with the left clamp body 10.

[0039] A rotating shaft 112 is movably inserted into the C-shaped block 111 at the front end of the right clamp body 11. A screw 113 is vertically fixed on the rotating shaft 112, and a nut 114 is threaded onto the screw 113. When the left and right clamp bodies 11 are closed, the screw 113 is inserted into the U-shaped fixing plate 105 of the left clamp body 10. Tightening the nut 114 makes it press against the U-shaped fixing plate 105, thus completing the fixing of the clamp body.

[0040] The bottom of the right clamp body 11 is equipped with a pressure relief valve 110, which is used to introduce the medium into the protection and recovery component 2 when pressure accumulates in the clamp body due to leakage; a suction valve 115 is also provided on one side, which can be connected to external equipment to clean the residual medium in the clamp body.

[0041] The protection and recycling component 2 includes several tanks 22 connected in series (the number can be adjusted according to actual needs). Each tank 22 is equipped with a discharge valve 24 at the bottom for subsequent processing of the collected medium. Adjacent tanks 22 are connected by a pipe 23, and each pipe 23 is equipped with a solenoid valve 25, which is controlled by the main control board.

[0042] The pressure relief valve 110 of the right clamp body 11 is connected to the first storage tank 22 through the conduit 20. A one-way valve 21 is also installed on the conduit 20 (located between the storage tank 22 and the drive shaft 30 described later) to ensure that the medium can only flow into the storage tank 22 in one direction and prevent backflow.

[0043] The first storage tank 22 is equipped with a pressure sensor 26 on top to monitor the pressure inside the tank. When the pressure reaches the set threshold, the main board controls the opening of the solenoid valve 25 of the corresponding pipe 23 to introduce the medium into the next storage tank 22, thus realizing staged storage.

[0044] The dual warning assembly 3 includes a drive shaft 30 mounted on the conduit 20. Four drive blades 31 are fixed on a section of the drive shaft 30 located inside the conduit 20. When the leaking medium flows through the conduit 20, the impact drive blades 31 drive the drive shaft 30 to rotate. One end of the drive shaft 30 is connected to the kinetic energy generator 32 via a coupling 34. After the rotational kinetic energy is converted into electrical energy, it powers the second warning light 33 on the kinetic energy generator 32, causing it to light up and forming a dual warning parallel to the first warning light 109.

[0045] During installation, the left and right clamps 11 are closed and fixed at the connection between the valve flange and the pipe flange, and the sealing strip 4 ensures a seal. When leakage occurs, the sensor detects the signal and transmits it to the control board, triggering the alarm light 109 to flash (level one warning). The accumulation of leaked medium causes the pressure in the sealed space to rise, the pressure relief valve 110 opens, and the medium flows to the storage tank 22 through the conduit 20. The flowing medium drives the transmission blade 31 to rotate, causing the kinetic energy generator 32 to drive the alarm light 33 to light up (level two warning). After the pressure in the first storage tank 22 reaches the standard, the pressure sensor 26 triggers the solenoid valve 25 to open, and the medium is introduced into the next storage tank 22 to achieve safe recovery. The medium in the storage tank 22 is then processed through the discharge valve 24.

[0046] This implementation method, through targeted structural design, is precisely adapted to leakage monitoring of flange connection parts, and has the functions of damage prevention, media recovery and dual warning, making it suitable for valve monitoring scenarios with high safety requirements.

[0047] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
