Description
Technical field
The present invention relates to a kind of auxiliary charger, particularly relate to a kind of link in order to be connected gas-filled pump and inflatable product, inflatable product is as inflation sail, air mattress, inflatable dinghy or inflation surfboard etc.
Background technique
It is all provided with air valve for the equipment of comparatively large-scale needs inflation such as air mattress, inflatable dinghy.The kind of air valve is broadly divided into two classes according to purposes, one class is the gas charging valve in order to inflation, a kind of gas charging valve as disclosed in the patent No. Chinese utility model patent " a kind of gas charging valve " that is ZL201120322164.8 (notification number is CN202203458U), comprise housing, there is in housing the active chamber be communicated with working environment and the air-inlet cavity be in communication with the outside, be interconnected by valve port between active chamber and air-inlet cavity, valve port position is provided with nonreturn valve core assembly, and this nonreturn valve core assembly only allows air to enter active chamber from air-inlet cavity.Another kind of is the safety valve guaranteeing inflatable safety, during inflation, by safety valve energy releasing pressure automatically when air pressure as inflatable product inside is too high, prevent inflatable product from being filled quick-fried, this safety valve has certain cracking pressure, and when the pressure in salvage boat is greater than the cracking pressure of safety valve, pressure release opened by safety valve, when pressure is less than the cracking pressure of safety valve, safety valve cuts out.Conventional Direct spring loaded safety valve includes the valve body be threaded on valve seat, there is in valve body the active chamber be communicated with working environment and the exhaust cavity be in communication with the outside, be interconnected by valve port between active chamber and exhaust cavity, the valve rod held by spring is provided with in active chamber, pass the valve rod upper end after valve port and be provided with seal washer, under the action of the spring, valve rod is made to move down trend, and then make seal washer keep laminating valve port trend, so that active chamber and exhaust cavity are blocked, when the pressure in active chamber is higher than the support force of spring to valve rod, namely when working pressure is higher than base measuring pressure set by safety valve, air pressure or oil pressure can act on valve rod, make valve rod moves, and then the seal washer of band ovable valve stem upper end moves, too high pressure is just discharged to the external world by the gap between seal washer and valve port from exhaust cavity, pressure in active chamber reduces, when working pressure is lower than the support force of spring to valve rod, spring can be with again ovable valve stem to move down, valve port is closed by seal washer again, blocking-up active chamber is communicated with exhaust cavity.
For this reason, inflatable product 1 ' is arranged gas charging valve 2 ' and become a kind of standard configuration with safety valve 3 ', as shown in figure 12, during inflation, one end of inflated hose 4 ' is connected with gas-filled pump 5 ', the other end of inflated hose 4 ' is connected with gas charging valve 5 ', and the inflated hose 6 ' of this end can back down the nonreturn valve core on gas charging valve 2 ' automatically, inflating.Gas-filled pump 5 ' works to inflatable product 1 ' inflation, and safety valve 3 ' plays and prevents from filling quick-fried function.
Because existing inflatable product will arrange two kinds of valves, add the cost of inflatable product, in addition because the existence of two valves increases the rate of fault of inflatable product simultaneously, be also inconvenient to fold inflatable product.
