Description

Technical Field

[0001] This application relates to the field of gas cylinder technology, specifically to a monitoring valve for gas cylinders. Background Technology

[0002] A gas cylinder is a portable pressure vessel with a bottle-shaped main structure, typically filled with gas (compressed gas, liquefied gas, dissolved or adsorbed gas, etc.). A monitoring valve, also known as a gas cylinder valve, is a valve device used to control the on / off state and flow rate of gas, widely used in industries, laboratories, and homes. Its main function is to control the pressure and flow rate of the gas by adjusting the opening and closing components within the valve body, ensuring that the pressure and flow rate of the output gas remain stable. A gas cylinder valve includes components such as a valve stem, pressure regulating spring, elastic diaphragm device, and pressure reducing valve.

[0003] Existing gas cylinder valves make it inconvenient to monitor the gas pressure inside the cylinder and the connecting equipment, making it difficult for users to determine the gas content inside the cylinder and affecting its use.

[0004] Therefore, there is an urgent need for a monitoring valve for gas cylinders to solve the problem that monitoring valves are inconvenient for monitoring the internal gas pressure of gas cylinders. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a monitoring valve for gas cylinders, which has the advantage of real-time monitoring of the internal gas pressure of the gas cylinder, thus solving the problem that monitoring valves are inconvenient for monitoring the internal gas pressure of gas cylinders.

[0006] To achieve the above objectives, this application provides the following technical solution: a monitoring valve for gas cylinders, comprising a gas cylinder valve, a fixing nut, a connecting plate, and a connector. The fixing nut is threadedly connected to the gas outlet of the gas cylinder valve. The connecting plate is located at the end of the fixing nut away from the gas cylinder valve. The connector is installed on the outer surface of the connecting plate. A pressure gauge 1 and a pressure gauge 2 are provided on the outer surface of the connecting plate. A support ball is installed inside the connecting plate. A through hole 1 and a through hole 2 are provided inside the support ball. A connecting ball is installed at the center of the support ball.

[0007] The gas cylinder is connected via a connector, a gas cylinder valve, a fixing nut, and a connecting plate. Pressure gauge 2 is connected to the inside of the gas cylinder valve through a through hole 1, allowing pressure gauge 2 to continuously monitor the pressure inside the gas cylinder, thereby determining the amount of gas inside the cylinder and making the gas cylinder valve more convenient to use.

[0008] Preferably, the gas cylinder valve is connected to the pressure gauge via a fixing nut and a through hole.

[0009] Preferably, the connector is connected to the pressure gauge through the second through hole.

[0010] Preferably, a connecting rod is installed on the outer surface of the connecting ball, an indicator head is fixedly connected to the end of the connecting rod away from the connecting ball, the connecting rod is rotatably connected to the support ball, and a connecting hole is provided inside the connecting ball.

[0011] Preferably, the bottom of the gas cylinder valve is provided with a connector, a limiting piece is welded to the outer surface of the connector, and a rubber pad is installed in the groove at the bottom of the limiting piece.

[0012] Preferably, the outer surface of the connecting ball is in close contact with the inner side of the supporting ball.

[0013] In summary, this application includes at least one of the following beneficial effects:

[0014] 1. This gas cylinder uses a monitoring valve. When the gas cylinder valve is connected to the gas cylinder, the gas cylinder is connected through the connector, gas cylinder valve, fixing nut and connecting plate. Pressure gauge 2 is connected to the inside of the gas cylinder valve through through hole 1, so that pressure gauge 2 can detect the pressure inside the gas cylinder in real time, thereby determining the amount of gas inside the gas cylinder. At the same time, pressure gauge 1 is connected to the connector through through hole 2, so that pressure gauge 1 can monitor the pressure of the connector connected to external equipment, making the use of the gas cylinder more convenient.

[0015] 2. The gas cylinder uses a monitoring valve. When the gas cylinder valve drives the connector to rotate and fix to the top of the gas cylinder, the rubber pad is placed between the limiting plate and the gas cylinder, so that the gas cylinder valve and the gas cylinder can be tightly connected. At the same time, the limiting plate tightly presses the rubber pad onto the gas cylinder, so that the gas cylinder valve and the gas cylinder are tightly connected, preventing gas leakage and improving the safety of the gas cylinder valve.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1-5 A monitoring valve for gas cylinders includes a gas cylinder valve 1, a fixing nut 2, a connecting plate 3, and a connecting member 4. The fixing nut 2 is threaded to the outlet of the gas cylinder valve 1. The connecting plate 3 is located at the end of the fixing nut 2 away from the gas cylinder valve 1. The connecting member 4 is installed on the outer surface of the connecting plate 3. A pressure gauge 5 and a pressure gauge 6 are provided on the outer surface of the connecting plate 3. A support ball 9 is installed inside the connecting plate 3. The support ball 9 has a through hole 10 and a through hole 11. A connecting ball 12 is installed at the center of the support ball 9. The gas cylinder valve 1 is connected to the pressure gauge 6 through the fixing nut 2 and the through hole 10. The connecting member 4 is connected to the pressure gauge 5 through the through hole 11. A connecting rod 8 is installed on the outer surface of the connecting ball 12. An indicator head 7 is fixedly connected to the end of the connecting rod 8 away from the connecting ball 12. The outer surface of the connecting ball 12 is tightly fitted with the inner side of the support ball 9. The connecting rod 8 is rotatably connected to the support ball 9. A connecting hole 13 is provided inside the connecting ball 12.

[0024] Through the above technical solution, the gas cylinder valve 1 is composed of components such as a valve push rod, a pressure regulating spring, an elastic diaphragm device, and a pressure reducing valve. When the gas cylinder valve 1 is installed on the top of the gas cylinder, the gas cylinder is connected through the connector 14, the gas cylinder valve 1, the fixing nut 2, and the connecting plate 3. The pressure gauge 6 is connected to the inside of the gas cylinder valve 1 through the through hole 10, so that the pressure gauge 6 can detect the pressure inside the gas cylinder in real time, thereby determining the amount of gas inside the gas cylinder. At the same time, the pressure gauge 5 is connected to the connector 4 through the through hole 11, so that the pressure gauge 5 can monitor the connection of the connector 4. The pressure of the external equipment is detected by pressure gauge 5 and pressure gauge 6 to check the internal and external air pressure of the gas cylinder, making the use of gas cylinder valve 1 more convenient. When the operator rotates the indicator head 7, the indicator head 7 drives the connecting ball 12 to rotate through the connecting rod 8. When the indicator head 7 rotates to the horizontal position, the indicator head 7 drives the connecting ball 12 to rotate through the connecting rod 8, so that the through hole 10, the connecting hole 13 and the through hole 2 11 are connected, so that the gas cylinder is connected to the external equipment. When the connecting ball 12 drives the connecting hole 13 to shift, the through hole 10 and the through hole 2 11 are disconnected.

[0025] Specifically, a connector 14 is provided at the bottom of the gas cylinder valve 1, a limit plate 15 is welded to the outer surface of the connector 14, and a rubber pad 16 is installed in the groove at the bottom of the limit plate 15.

[0026] With the above technical solution, when the gas cylinder valve 1 drives the connector 14 to rotate and fix to the top of the gas cylinder, the rubber pad 16 is placed between the limiting plate 15 and the gas cylinder, so that the gas cylinder valve 1 and the gas cylinder can be tightly connected. At the same time, the limiting plate 15 tightly presses the rubber pad 16 onto the gas cylinder, so that the gas cylinder valve 1 and the gas cylinder are tightly connected, preventing gas leakage.

[0027] In use, the gas cylinder is connected through connector 14, gas cylinder valve 1, fixing nut 2 and connecting plate 3. Pressure gauge 2 6 is connected to the inside of gas cylinder valve 1 through through hole 10, so that pressure gauge 2 6 can detect the pressure inside the gas cylinder in real time, thereby determining the amount of gas inside the gas cylinder, making gas cylinder valve 1 more convenient to use.
