Description

Technical Field

[0001] This utility model relates to the field of ammonia system technology, specifically to a multi-safety cutoff and monitoring device for ammonia systems. Background Technology

[0002] Ammonia systems refer to a class of systems that use ammonia as the primary working medium and are widely used in refrigeration, chemical, and agricultural fields. Ammonia, as a highly efficient refrigerant and chemical raw material, possesses unique physical and chemical properties that make it perform exceptionally well in specific applications. While ammonia boasts high-efficiency refrigeration performance and environmental friendliness, its flammable, explosive, and toxic characteristics also present corresponding challenges.

[0003] Based on the above, the inventors have discovered the following problems: current leak-proof valves can only be triggered to shut off and seal the pipeline when it leaks, which is a relatively simple function. Moreover, leak-proof valves are prone to failure if not properly maintained, resulting in the inability to provide safety protection for the pipeline and making them inconvenient to use.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a multi-safety cut-off and monitoring device for ammonia systems, in order to achieve a more practical purpose. Utility Model Content

An explosion-proof valve assembly is fixedly installed at one end of the monitoring section, and a solenoid valve assembly is fixedly installed at the other end of the monitoring section. A control box is fixedly installed on the outer side of the top of the monitoring section. A pressure sensor, a temperature sensor, and a flow meter are fixedly installed at the bottom of the control box. The monitoring ends of the pressure sensor, temperature sensor, and flow meter are all located inside the monitoring section. The control box contains a monitoring system, which is electrically connected to the pressure sensor, temperature sensor, and flow meter. The monitoring system contains a control module, a remote communication module, and a storage module.

[0007] By adopting the above technical solution, an explosion-proof valve assembly is fixedly installed at one end of the monitoring section, and a solenoid valve assembly is fixedly installed at the other end. This allows the explosion-proof valve assembly to cut off the ammonia system piping in an emergency. The solenoid valve assembly allows users to control the on / off of the ammonia system piping as needed and can also supplement the explosion-proof valve assembly, improving the safety performance of the device. The pressure sensor, temperature sensor, and flow meter monitoring ends are all located inside the monitoring section, facilitating the monitoring of the flow rate, temperature, and pressure of the ammonia liquid flowing through the monitoring section, and facilitating the monitoring of the working status of the ammonia system pipeline.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a multi-safety shut-off and monitoring device for an ammonia system, including a monitoring component 101. The monitoring component 101 includes a monitoring section 10101, with an explosion-proof valve assembly 102 fixedly installed at one end of the monitoring section 10101 and a solenoid valve assembly 103 fixedly installed at the other end. The fixed installation of the explosion-proof valve assembly 102 at one end of the monitoring section 10101 and the solenoid valve assembly 103 at the other end facilitates the emergency shutdown of the explosion-proof valve assembly 102. 02 can cut off ammonia system pipe fittings. The solenoid valve assembly 103 allows users to control the on / off of ammonia system pipe fittings as needed, and can also supplement the explosion-proof valve assembly 102 to improve the safety performance of the device. A control box 10102 is fixedly installed on the outer side of the top of the monitoring section 10101. A pressure sensor 10103, a temperature sensor 10104, and a flow meter 10105 are fixedly installed at the bottom of the control box 10102. The monitoring ends of the pressure sensor 10103, temperature sensor 10104, and flow meter 10105 are all located in the monitoring section. Inside monitoring section 10101, pressure sensor 10103, temperature sensor 10104, and flow meter 10105 are all located within the monitoring section 10101. This facilitates the monitoring of the flow rate, temperature, and pressure of ammonia liquid flowing through the monitoring section 10101, enabling monitoring of the pipeline's operational status in the ammonia system. Control box 10102 houses a monitoring system electrically connected to pressure sensor 10103, temperature sensor 10104, and flow meter 10105. The monitoring system includes a control module, a remote communication module, and a storage module. The storage module stores the monitoring data from these sensors, while the control module analyzes and processes the collected data and controls the operation of the device. The remote communication module allows users to remotely access the monitoring data using a mobile terminal.

[0032] The control box 10102 has a display screen 10106 at one end of its top and a control button 10107 at the other end of its top.

[0034] The explosion-proof valve body 10201 has a valve core 10203 fixedly installed inside. The valve core 10203 has a sliding hole 10207 in the middle. A slide rod 10205 is inserted inside the sliding hole 10207. The sliding hole 10207 in the middle of the valve core 10203 and the slide rod 10205 inserted inside the sliding hole 10207 facilitate the limiting of the slide rod 10205, so that the slide rod 10205 can slide along the sliding hole 10207.

[0035] The valve core 10203 has a through hole 10204 on its surface. A sealing valve plate 10210 is fixedly installed on the end of the slide rod 10205 facing the monitoring component 101.

[0036] The sliding hole 10207 has a spring groove 10208 at one end facing the monitoring component 101. A push spring 10209 is fixedly installed inside the spring groove 10208. The push spring 10209 is sleeved on the outside of the slide rod 10205. The other end of the push spring 10209 is fixedly connected to the sealing valve plate 10210. By sleeved on the outside of the slide rod 10205 and fixedly connected to the sealing valve plate 10210, the push spring 10209 can provide elastic force to move the sealing valve plate 10210 away from the through hole 10204. When the ammonia system pipeline ruptures, the pressure difference on both sides of the sealing valve plate 10210 will push the sealing valve plate 10210 towards the valve core 10203, thus blocking the through hole 10204.

[0037] The slide rod 10205 has a threaded outer side at the end away from the sealing valve plate 10210, and an adjusting nut 10206 is threaded to the end of the slide rod 10205 away from the sealing valve plate 10210. The threaded outer side of the end of the slide rod 10205 away from the sealing valve plate 10210 and the adjusting nut 10206 threaded to the end of the slide rod 10205 away from the sealing valve plate 10210 facilitates the adjustment of the distance between the sealing valve plate 10210 and the valve core 10203, thereby adjusting the sensitivity of the explosion-proof valve assembly 102.

[0038] The solenoid valve assembly 103 includes a solenoid valve body 10301. One end of the solenoid valve body 10301 is connected to the monitoring section 10101, and the other end of the solenoid valve body 10301 is fixedly installed with an inlet flange 10303. The inlet flange 10303 fixedly installed at the other end of the solenoid valve body 10301 facilitates connection to external pipelines and facilitates the guidance of ammonia liquid into the device.

[0039] The solenoid valve body 10301 has an actuator 10302 fixedly installed on its top. The actuator 10302 is electrically connected to the monitoring system. The connection between the actuator 10302 and the monitoring system facilitates the monitoring system to control the opening and closing of the solenoid valve assembly 103, allowing users to remotely control the ammonia system pipeline. It can also cut off the pipeline when the pressure sensor 10103 detects an abnormal pressure, thus improving safety performance.

[0040] Specifically, the working principle of this multi-safety shut-off and monitoring device for ammonia systems is as follows: During use, an inlet flange 10303 is fixedly installed at the other end of the solenoid valve body 10301, facilitating connection to external pipelines and guiding ammonia liquid into the device. The outlet flange 10202 facilitates connection between the device and external pipelines, guiding ammonia liquid out of the device. The display screen 10106 and control button 10107 are both electrically connected to the monitoring system. The display screen 10106 shows the device's operating status, and the control button 10107 allows the user to control the device. The pressure sensor 10103, temperature sensor 10104, and flow meter 10105 are all located inside the monitoring section 10101, facilitating... The system monitors the flow rate, temperature, and pressure of ammonia liquid flowing through monitoring section 10101, facilitating the monitoring of the ammonia system's pipeline operating status.

An internal sliding rod 10205 is inserted to limit its movement, allowing it to slide along the sliding hole 10207. A sealing valve plate 10210 is fixedly installed on the end of the sliding rod 10205 facing the monitoring component 101. When the sliding rod 10205 slides towards the outlet flange 10202, the sealing valve plate 10210 blocks the through hole 10204, effectively cutting off the ammonia system pipeline. A push spring 10209 is sleeved on the outside of the sliding rod 10205, with its other end fixedly connected to the sealing valve plate 10210. This allows the push spring 10209 to provide elasticity, moving the sealing valve plate 10210 away from the through hole 10204. When the ammonia system pipeline ruptures, the sealing valve plate 10210... The pressure difference on both sides pushes the sealing valve plate 10210 towards the valve core 10203, blocking the through hole 10204.
