Description
Technical Field
[0001] The utility model relates to the technical field of inflation interfaces, in particular to a high-pressure gas inflation interface. Background Art
[0002] The charging interface is a device used to connect the charging equipment with the gas to be charged, and is commonly found in gas cylinders, gas cylinder pressure gauges, gas cylinder pressure testers and other equipment. Its main function is to achieve rapid filling and sealing of gas, to ensure that the gas does not leak, thereby improving the safety and accuracy of the charging. When high-pressure gas is charged, it is generally necessary to pass through the charging interface to charge the gas inside the gas storage tank into the required gas device. The charging interface is one of the indispensable and important components in the field of gas filling, and its quality and performance directly affect the effect and safety of the charging.
[0003] However, the above-mentioned device has the following disadvantages: during the installation of the existing inflation interface, due to the weight of the inflation interface itself, the installer needs to hold the inflation interface and align it with the inflation hole before installing it. If it is not accurately aligned, it will be impossible to install. This requires at least two workers to install it, and there is no protective device or reinforcement device at the interface. The interface is generally fragile. If no protective reinforcement measures are taken, the interface will fall off.
[0004] Therefore, it is necessary to provide a high-pressure gas inflation interface to solve the above technical problems. Utility Model Content
[0005] The utility model aims to provide a high-pressure gas charging interface, which adopts a clamping ring and a screw rod and has the effect of aligning first and then installing.
[0006] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a high-pressure gas inflation interface, comprising a pressure reducing valve, a connecting port is opened at the top end of the pressure reducing valve, an inflation tube is arranged at the bottom end of the pressure reducing valve, a threaded groove is opened at the top end of the inflation tube, the inflation tube is threadedly connected to the pressure reducing valve through the threaded groove, connecting rods are fixedly connected on both sides of the inflation tube, slip rings are slidably installed on the side walls of the inflation tube, screw rods are respectively rotatably connected on both sides of the slip ring, sliding rods are fixedly connected on both sides of the slip ring, hand wheels are fixedly connected at one end of the two screw rods, moving blocks are slidably connected to the two sliding rods, the two moving blocks are respectively threadedly connected to the two screw rods, the bottom ends of the two moving blocks are fixedly connected to support rods, the bottom ends of the two support rods are fixedly connected to clamp rings, and the two clamp rings are respectively arranged on both sides of the inflation tube.
[0007] By adopting the above technical scheme, the pressure reducing valve is a prior art, and its function is a valve that can adjust the pressure of the gas cylinder, which can reduce the gas pressure and stabilize it to a fixed value. When it is necessary to connect the inflation pipe to the inflation port of the required inflation device, first rotate the hand wheels at both ends to rotate the screws at both ends. Under the limiting action of the moving blocks and the sliding rods, the moving blocks at both ends move toward the middle. After the clamping rings at the bottom ends of the two moving blocks clamp the inflation port of the inflation device, loosen the bolts so that the slip ring can slide on the inflation pipe. At this time, rotate the connecting rods at both ends. Since the inflation pipe and the pressure reducing valve are threadedly connected, the inflation pipe can be moved downward to the inflation port. Then tighten the bolts to fix the slip ring on the inflation pipe. Then the staff connects the inflation pipe and the inflation port. After the connection is completed, the inflation operation can be realized. The air extraction valve is connected through the connecting port, and the inflation speed is controlled by the pressure reducing valve. The alignment and fixation are first realized, and then the installation operation is realized. The clamping ring can protect and protect the interface, which increases the practical performance and safety protection performance of the device.
[0008] The utility model is further configured as follows: a threaded hole is provided on the side wall of the slip ring, a bolt is threadedly connected to the threaded hole, and the bolt passes through the side wall of the slip ring and is pressed on the side wall of the inflation tube.
[0009] By adopting the above technical solution, the fixation and sliding of the slip ring can be controlled by the tightness of the bolts, thereby increasing the practical performance of the device.
[0010] The utility model is further configured as follows: inner walls of the two clamping rings are both provided with rubber pads.
[0011] By adopting the above technical solution, the rubber pad is relatively soft, and when the clamp ring clamps the interface, the rubber pad can protect the interface, thereby increasing the practical performance of the device.
[0012] The utility model is further configured as follows: a one-way valve is fixedly installed inside the inflation tube.
[0013] By adopting the above technical solution, the one-way valve is an existing technology, and its function is to allow gas or liquid to flow in one direction, with one-way flowability, thus realizing the anti-backflow function.
[0014] The utility model is further configured as follows: a sealing ring is fixedly installed at the bottom end of the inflation tube.
[0015] By adopting the above technical solution, the sealing ring can increase the sealing performance of the inflation tube and the inflation interface, prevent air leakage, and increase the practicality and sealing performance of the device.
[0016] The utility model is further configured as follows: a friction ring is fixedly mounted on the side wall of the pressure reducing valve, and an air pressure sensor is arranged on the side wall of the pressure reducing valve.
[0017] By adopting the above technical solution, the friction ring can increase the friction between the hand and the pressure reducing valve to prevent the hand and the pressure reducing valve from slipping during the installation process. The air pressure sensor can monitor the air pressure changes inside the pressure reducing valve during inflation, thereby increasing the practical performance of the device.
[0018] In summary, the utility model has the following beneficial effects: the pressure reducing valve of the utility model is a prior art, and its function is a valve that can adjust the pressure of the gas cylinder, which can reduce the gas pressure and stabilize it to a fixed value. When the inflation tube needs to be connected to the inflation port of the required inflation device, the hand wheels at both ends are first rotated to rotate the screws at both ends. Under the limiting action of the moving block and the sliding rod, the moving blocks at both ends move toward the middle. After the clamping rings at the bottom ends of the two moving blocks clamp the inflation port of the inflation device, the bolts are loosened so that the slip ring can slide on the inflation tube. At this time, the connecting rods at both ends are rotated. Since the inflation tube and the pressure reducing valve are threadedly connected, the inflation tube can be moved downward to the inflation port, and then the bolts are tightened to fix the slip ring on the inflation tube. Then the staff connects the inflation tube and the inflation port. After the connection is completed, the inflation operation can be realized. The air extraction valve is connected through the connecting port, and the inflation speed is controlled by the pressure reducing valve, which realizes the operation of first aligning and fixing, and then realizing the installation operation. The clamping ring can protect and protect the interface, which increases the practical performance and safety protection performance of the device. BRIEF DESCRIPTION OF THE DRAWINGS
