Description

Inflation connector

Technical Field

The utility model belongs to the technical field of the fire extinguisher filling is aerifyd, concretely relates to inflation joint.

Background

The dry powder type fire extinguisher needs to fill gas into the tank body after the powder filling process, so that the pressure in the tank body is enough, an inflation connector is needed to be directly butted with a valve on the tank body for inflation during inflation, most of the existing inflation connectors are directly communicated with a gas inlet and a gas outlet, and dust in the tank body is easily blown due to high air pressure.

SUMMERY OF THE UTILITY MODEL

To the not enough of description among the above-mentioned prior art, the utility model provides an air inflation connects.

The utility model discloses the technical scheme who adopts does:

an inflation connector comprises a connector body, wherein the connector body is provided with an inflation cavity, an inflation inlet and an inflation outlet, the inflation inlet and the inflation outlet are communicated with the inflation cavity, and a buffer structure is arranged at the position, opposite to the inflation inlet, of the inflation cavity. The buffer structure prevents high-pressure gas from directly scouring the inflatable cavity and then directly entering the tank body at high pressure, and reduces the degree of scouring dust in the tank body.

As the utility model discloses an optimal scheme, the axis of aerifing the import is crossing with the axis of aerifing the chamber, buffer structure is the dashpot, aerifys the import and aerifys the export not on a straight line, and both do not directly link up to aerify the high-pressure gas that the import came in and can wash away the dashpot earlier, alleviate certain wind speed, from aerifing the chamber entering and aerifing the export after the lateral wall reposition of redundant personnel of dashpot, thereby it is internal to get into the jar from the export of giving vent to anger.

As an optimized proposal of the utility model, the buffer slot is a conical buffer slot. The air inlet directly washes the conical buffer groove, and is dispersed along the side wall of the conical buffer groove to enter the inflation cavity and then discharged from the inflation cavity and the inflation outlet; the conical structure can better divide the high-pressure gas.

As an optimized scheme of the utility model, install elasticity at the joint body and go out the gas head, elasticity goes out the gas head for rubber goes out the gas head. The air outlet hole of the elastic air outlet head is communicated with the air inflation outlet, and the elastic air outlet head can better enable the connection part of the air inflation connector and the tank body to be in sealing connection, so that air leakage is avoided.

As a preferred scheme of the utility model, the position that connects the body to be located the inflation export is equipped with mounting groove, and elasticity goes out the gas head and installs in mounting groove and the cover is established on the inflation export. This arrangement allows the resilient gas outlet head to be replaceable.

As an optimized proposal of the utility model, the one end of the connector body which is far away from the outlet of the inflation is provided with a connecting piece. The connecting piece is used for being connected with external driving pieces such as cylinders, and the external driving pieces drive the joint body to move integrally through the connecting piece.

The utility model relates to an aerify import and aerify the export and not at same straight line to set up the dashpot in aerifing the chamber that aerifys import correspondence, can shunt the high-pressure gas of just advancing, reduce and directly erode aerifing the holistic directness in chamber, but also can reduce the wind speed, avoid the wind pressure too big, and still set up elasticity gas outlet head in aerifing the exit, just can be in order to ensure when using with the inflation inlet sealing connection of the jar body. The utility model discloses simple structure, but the result of use is fine, long service life moreover.
