Abstract

The invention discloses a portable inflating device, which comprises a fast inflating valve and an inflating main control box, wherein the fast inflating valve comprises a handle, a valve rod which is fixedly connected with the handle and is provided with a valve rod sealing ring, a valve body which is in threaded connection with the valve rod, a quick joint which is in threaded connection with the valve body, a valve core which is in clearance fit with the quick joint, and a joint communicated with an inner cavity of the valve body 5; the outer end of the joint is connected with one end of a hose; the other end of the hose is connected with one end of the quick joint; the other end of a second quick joint is connected with a corresponding air outlet joint of the inflating main control box according to inflating needs; the inflating main control box comprises an air inlet joint; after the air inlet joint is connected with an air inlet pressure gage, four air outlet pipelines are branched; low-pressure and medium-pressure air outlet pipelines comprise stop valves, pressure-reducing valves and air outlet pressure gages; and high-pressure air outlet pipelines comprise stop valves and air outlet pressure gages. The inflating device can inflate and supply air on site and is easy to operate quickly and safely, and a beginner can flexibly, rapidly and safely operate the device after reading instructions.

Description

technical field [0001] The invention relates to an inflatable device, in particular to a portable inflatable device. Background technique [0002] Since the metering pump has a pulsating output, in order to stabilize the pressure and flow of the metering pump, the accumulator becomes an essential accessory of the metering pump. Due to the long-term use of the accumulator, there is a phenomenon of gas loss. The traditional way of charging and replenishing gas is laborious and laborious. It must be disassembled and sent to the charging station for charging. The inflation method is complicated, cumbersome and dangerous, and it is difficult for beginners to operate. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a portable inflatable device that can perform on-site inflation and replenishment, and has the advantages of simple, fast and safe operation. , The character...
