Description

Technical Field

[0001] The utility model relates to the technical field of gas monitoring, in particular to a monitoring device for a gas pressure regulator cut-off valve. Background Art

[0002] According to the "Urban Gas Technical Specifications", "Urban Gas Design Specifications", "Gas Engineering Project Specifications" and other regulations, gas pressure regulators should be equipped with safety protection measures to prevent the gas outlet pressure from exceeding the allowable value of downstream pressure, so as to prevent hidden dangers of downstream gas use caused by excessively high gas outlet pressure.

[0003] With the advancement of smart gas, the intelligent transformation of pressure regulators is becoming increasingly prominent. While there are established examples for monitoring pressure regulator operating pressure and filter differential pressure, monitoring the status of the pressure regulator shut-off valve (open or closed) is relatively rare. The pressure regulator shut-off valve is a key parameter for determining its operating status. If the shut-off valve is closed, it will affect downstream gas consumption. Gas companies should promptly arrange personnel to inspect the pressure regulator on-site and restore the shut-off valve status after verification. Currently, the status of the pressure regulator shut-off valve is generally determined by gas users who call the gas company after discovering a lack of gas during use. Gas companies lack proactive assessment of the status of the pressure regulator shut-off valve. Utility Model Content

[0004] In order to solve the above problems, the present invention aims to propose a gas pressure regulator shut-off valve monitoring device. By adding a shut-off valve action monitoring component to the pressure regulator, the operating status of the pressure regulator shut-off valve can be collected, thereby solving the problem of remote monitoring of the gas pressure regulator shut-off valve.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A gas pressure regulator shut-off valve monitoring device includes a pressure regulator body. A shut-off valve actuation monitoring assembly is installed near the periphery of the shut-off valve actuation end of the pressure regulator body. The shut-off valve actuation monitoring assembly is electrically connected to an RTU or DTU remote monitoring terminal for monitoring a vibration signal at the shut-off valve actuation end and transmitting the signal to the RTU or DTU remote monitoring terminal.

[0007] Furthermore, fixing holes are provided at the upper and lower ends of the housing of the shut-off valve action monitoring assembly, and the shut-off valve action monitoring assembly is fixedly mounted on the shut-off valve action end of the voltage regulator body through the fixing holes in conjunction with binding straps.

[0008] Furthermore, a non-slip rubber pad is provided at the contact end of the shut-off valve action monitoring component and the outer periphery of the shut-off valve action end of the pressure regulator body.

[0009] Furthermore, the shut-off valve action monitoring component is provided with a vibration sensor, a relay, a power interface, a signal interface and an indicator light. The vibration sensor is used to sense the shut-off valve action of the voltage regulator body. The relay is connected to the vibration sensor for outputting an alarm signal. The relay is connected to the RTU or DTU remote monitoring terminal through the signal interface, and the power interface is connected to the power supply end of the RTU or DTU remote monitoring terminal. The indicator light is used to visually display the alarm signal.

[0010] Furthermore, it also includes a sensitivity regulator, which is controllably connected to the vibration sensor.

[0011] Beneficial effect: The utility model fixes the shut-off valve action monitoring component on the valve body at the periphery of the shut-off valve action end of the pressure regulator body. When the shut-off valve performs the "shut-off" action, the valve body will vibrate. After receiving the "vibration" signal, the monitoring component transmits the signal to the remote monitoring terminal such as RTU or DTU through electrical connection. The remote monitoring terminal then transmits the signal to the background control terminal. The gas management personnel will know that the shut-off valve of the pressure regulator has produced a shut-off action and can send people to deal with it. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0018] Example 1

[0019] See also Figure 1-3: A gas pressure regulator shut-off valve monitoring device includes a pressure regulator body 1, and a shut-off valve action monitoring component 2 is installed near the outer periphery of the shut-off valve action end of the pressure regulator body 1. The shut-off valve action monitoring component 2 is electrically connected to the RTU or DTU remote monitoring terminal for monitoring the vibration signal of the shut-off valve action end and sending it to the RTU or DTU remote monitoring terminal.

[0020] In this embodiment, the shut-off valve action monitoring component is fixed to the valve body on the periphery of the shut-off valve action end of the pressure regulator body. When the shut-off valve performs the "shut-off" action, the valve body will vibrate. After receiving the "vibration" signal, the monitoring component transmits the signal to a remote monitoring terminal such as an RTU or DTU through an electrical connection. The remote monitoring terminal then transmits the signal to the background control terminal. The gas management personnel will then know that the shut-off action of the pressure regulator shut-off valve has occurred and can send personnel to deal with it.

[0021] In a specific example, the upper and lower ends of the shell of the shut-off valve action monitoring component 2 are provided with fixing holes 201, and the shut-off valve action monitoring component 2 is fixedly installed on the shut-off valve action end of the voltage regulator body 1 through the fixing holes 201 in conjunction with the binding straps 3.

[0022] In a specific example, a non-slip rubber pad 202 is provided at the peripheral contact end of the shut-off valve actuation end of the shut-off valve actuation end of the pressure regulator body 1 and the shut-off valve actuation monitoring component 2 .

[0023] In this embodiment, the shut-off valve action monitoring assembly is fixed to the valve body at the shut-off valve action end by tying a cable tie through a fixing hole; a non-slip rubber pad is provided at the contact portion between the shut-off valve action monitoring assembly and the shut-off valve body, which is used to increase the friction resistance between the shut-off valve action monitoring assembly and the shut-off valve body, thereby better fixing the shut-off valve action monitoring assembly to the shut-off valve body.

[0024] It should be noted that the shut-off valve action monitoring component of this embodiment is suitable for various types of pressure regulator shut-off valves currently on the market, has high acquisition accuracy, does not apply external force to the internal actuating end of the pressure regulator shut-off valve, and does not interfere with the action of the pressure regulator shut-off valve.

[0025] In a specific example, the shut-off valve action monitoring component 2 is provided with a vibration sensor 20, a relay 21, a power interface 22, a signal interface 23 and an indicator light 24. The vibration sensor 20 is used to sense the shut-off valve action of the voltage regulator body 1. The relay 21 is connected to the vibration sensor 20 for outputting an alarm signal. The relay 21 is connected to the RTU or DTU remote monitoring terminal through the signal interface 23. The power interface 22 is connected to the power supply end of the RTU or DTU remote monitoring terminal. The indicator light 24 is used to visually display the alarm signal.

[0026] The indicator light of this embodiment emits red light when the shut-off valve action monitoring component is vibrated; one end of the signal interface is electrically connected to the relay, and the other end is electrically connected to the RTU or DTU remote monitoring terminal, which is used to output a warning signal when the shut-off valve action monitoring component is vibrated; one end of the power interface is electrically connected to the shut-off valve action monitoring component, and the other end is electrically connected to the RTU or DTU remote monitoring terminal, and these remote terminals supply power to the entire shut-off valve action monitoring component; the relay is used to generate and output the warning signal. When the shut-off valve action monitoring component is vibrated, the relay outputs the warning signal through the signal interface; the vibration sensor is used to sense the action of the voltage regulator shut-off valve, convert the mechanical vibration amount into an electrical signal, and then the relay outputs the warning signal.

[0027] In a specific example, a sensitivity adjuster 25 is further included, and the sensitivity adjuster 25 is controllably connected to the vibration sensor 20 .

[0028] It should be noted that after installing the shut-off valve operation monitoring component, the shut-off valve operation monitoring component sensitivity can be adjusted according to the intensity of the shut-off action of the pressure regulator shut-off valve. Sliding the sensitivity adjuster to the right increases the sensitivity, increasing the range of vibration that can be sensed. Even small vibrations are detected by the shut-off valve operation monitoring component and can generate a "vibration" signal. Sliding the sensitivity adjuster to the left decreases the sensitivity, reducing the range of vibration that can be sensed. Larger vibrations are required for the shut-off valve operation monitoring component to sense and generate a "vibration" signal. When the shut-off valve operation monitoring component senses a "vibration" signal, the LED light turns red.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
