Detailed ways

The structural principle and working principle of the present invention will be described in more detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the quick inflation valve of the inflation device of the present invention includes a handle 7, a valve stem 1 with a valve stem sealing ring 3 fixedly connected to the handle 7, and the valve stem 1 and the valve stem sealing ring 3 are sealed separately, The valve body 5 threaded with the valve stem 1, the first quick joint 9 threaded with the valve body 5, the valve core 4 located in the cavity of the valve body 5 and the first quick joint 9 clearance fit, when the valve stem 1 rotates, It can push the valve core 4 to move. On one side of the valve stem 5, there is an exhaust hole 2 to discharge the gas in the quick inflation valve and the pipeline after the valve stem 1 is separated from the valve stem sealing ring 3. On the other side of the valve stem 5, there is a There is a joint 8 connected to the inner cavity of the valve body 5, the joint 8 is connected to the hose 12, the hose 12 is connected to the second quick joint 13, the valve stem 1 and the valve body 5 are sealed with a sealing ring, and the valve body 5 is connected to the first quick joint. The joint 9 is sealed with a gasket. In Fig. 1, 6 is the joint valve of the equipment to be inflated, 10 is the balance spool of the equipment to be inflated, and 11 is the quick connector spool of the equipment to be inflated.

The valve stem 1 and the valve core 4 adopt contact one-way transmission. Before inflating, first rotate the valve stem 1 of the quick inflation valve upwards, and then connect the first quick joint 9 with the equipment to be inflated. During this process, the valve core of the quick inflation valve 4. It has not been in contact with the quick connector spool 11 of the connected part, and will not be affected by the internal pressure of the inflatable device, so it can be easily connected. After the connection is completed, rotate the valve stem 1 downward to push the valve core 4 downward, and then the valve core 4 pushes the quick joint valve core 11 of the connected part to open the joint valve 6, and the quick inflation valve is fully connected with the equipment to be inflated. The process is simple and convenient, safe and reliable. It solves many problems caused by internal pressure when the traditional quick connector is used for direct connection.

The valve stem 1 and the valve stem sealing ring 3 are sealed separately, and there is a vent hole 2 on the valve stem 1, so as to seal the inner cavity of the quick inflation valve when inflated, and discharge the quick inflation valve and the pipeline after the inflation is completed. The remaining gas inside can not only ensure the sealing of the gas during the inflation process, but also make the exhaust smooth. Eliminate the inconvenience of disassembling and assembling the pipeline joints after inflation due to the internal pressure and the accompanying danger.

As shown in Fig. 2 and Fig. 3, the inflatable main control box of the present invention includes an air inlet joint 15. After the air inlet joint 15 is connected with the air inlet pressure gauge 19, four air outlet pipelines are branched out. The four air outlet pipelines These are the low-pressure gas outlet pipeline, the first medium-pressure gas outlet pipeline, the second medium-pressure gas outlet pipeline and the high-pressure gas outlet pipeline. The low-pressure air outlet pressure gauge 18-1 and the low-pressure air outlet joint 14-1 are sequentially connected. The gas outlet pressure gauge 18-2 and the first medium pressure gas outlet joint 14-2 are sequentially connected, and the second medium pressure gas outlet pipeline is composed of the second medium pressure pressure reducing valve 17-3, the third stop valve 16-3, the second The medium-pressure gas outlet pressure gauge 18-3 and the second medium-pressure gas outlet connector 14-3 are sequentially connected, and the high-pressure gas outlet pipeline is composed of the fourth cut-off valve 16-4, the high-pressure gas outlet pressure gauge 18-4 and the high-pressure gas outlet connector 14-4 sequentially connected components.

Each gas outlet pipeline in the inflatable main control box is independently controlled. In the low-pressure gas outlet pipeline, when high-pressure gas is input, the pressure is first reduced by the low-pressure pressure reducing valve 17-1, and then controlled by the first cut-off valve 16-1. Inflation opening and closing, in the first medium-pressure outlet pipeline, when high-pressure gas is input, the pressure is first reduced by the first medium-pressure pressure reducing valve 17-2, and then the opening and closing of the inflation is controlled by the second cut-off valve 16-2. , off, in the second medium pressure outlet pipeline, when the high-pressure gas is input, the pressure is first reduced by the second medium pressure pressure reducing valve 17-3, and then the opening and closing of the inflation is controlled by the third stop valve 16-3. In the high-pressure gas outlet pipeline, when the high-pressure gas is input, the opening and closing of the inflation are directly controlled by the fourth cut-off valve 16-4. The low-pressure reducing valve 17-1, the first medium-pressure reducing valve 17-2 and the second medium-pressure reducing valve 17-3 are all set perfectly at the time of leaving the factory, which avoids potential safety hazards caused by high-pressure damage to equipment. All joints in the inflatable main control box are welded.

As shown in Figure 4, during the inflation of the quick inflation valve, the valve stem 1 and the valve stem sealing ring 3 form a sealing surface, forming a sealed cavity in the quick inflation valve.

As shown in FIG. 5 , before and after the quick inflation valve is inflated, the valve stem 1 of the quick inflation valve is unscrewed away from the sealing ring 3 of the valve stem.

The connections between the various external parts of the inflatable device are connected by rubber hoses and quick connectors, which are easy to operate, can better adapt to the inflatable environment, and are convenient for operators to operate. The multi-head design allows the operator to detect the intake pressure and the pressure of the equipment to be inflated at any time, ensuring accurate and reliable operation and improving safety.

The invention is a portable inflatable device, which relies on the multi-stage air pressure control of the main inflatable control box to realize the hierarchical pressure control; relies on the quick inflatable valve to realize fast and simple connection with the equipment to be inflated under any pressure.

The working principle of a portable inflatable device of the present invention is as follows: firstly connect the rubber hose 12 to the appropriate pressure level outlet connector through the second quick connector 13 according to the specific inflation needs, and first unscrew the valve stem 1 of the quick inflation valve to leave the valve stem The sealing ring 3, then connect the first quick joint 9 with the equipment to be inflated, and rotate the valve stem 1 downward, the valve stem 1 forms a sealing surface with the valve stem sealing ring 3 first, and forms a sealing cavity in the quick inflation valve, the valve stem 1 Continue to rotate downward to push the valve core 4 downward, and then the valve core 4 pushes the quick joint valve core 11 of the equipment to be inflated to open the joint valve 6, and the quick inflation valve is completely connected to the equipment to be inflated. At this point, the current pressure of the device to be inflated can be seen on the corresponding outlet pressure gauge. Open the corresponding cut-off valve, start to inflate, observe the corresponding outlet pressure gauge, after reaching the predetermined pressure, close the corresponding stop valve first, and then unscrew the valve stem 1 of the quick inflation valve until the exhaust hole 3 discharges the remaining air in the pipeline. At this time, the corresponding outlet pressure gauge is reset to zero, disconnect the connection with the device to be inflated, and the inflation is completed.
