Description
Technical field
The utility model relates to a kind of inflation safety valves.
Background technique
Inflation safety valve is mainly used for the safeguard protection of hydraulic support column, and rising prevents the excessively high hydraulic branch of damage of system pressure
The effect of frame.Feature is that draining flow is big, rapid, and pressure maintaining is high after pressure release.Conventional pneumatic safety valve has the drawback that: high pressure gas
Body easy to leak, gasket are easily squeezed out from swivel nut inflating port under hyperbaric environment, and the inflating port of swivel nut is radial inflation, infinite place
Device, gas cannot discharge after being filled with.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of good airproof performances and can removal closed high pressure gas
Inflation safety valve.
To solve the above problems, the technical solution adopted in the utility model includes: including valve body, is mounted in the valve body
Main valve plug, sealing ring is equipped between the main valve plug and the valve body, swivel nut, feature are equipped at the air inlet of the valve body
Be: the swivel nut outer end is equipped with an axial inflating port, inner end is equipped with silk braid, opens up one group of Axial-running Out gas on the silk braid
Hole, is equipped with a gas valve core in the swivel nut, and described gas valve core one end is set on the swivel nut and the gas valve core and the silk
Reset spring is equipped between set, the axial inflating port side that the gas valve core corresponds to the swivel nut is equipped with position limit arm, the limit
Arm is equipped with air valve pad.
The inflation safety valve, it is characterised in that: the axial direction inflating port front end is equipped with targeting port.
The inflation safety valve, it is characterised in that: sealing ring is equipped between the swivel nut and valve body.
The inflation safety valve, it is characterised in that: sealing ring and retaining ring are equipped at the connector of the valve body.
The inflation safety valve, it is characterised in that: the swivel nut outer end is equipped with two installing ports.
The inflation safety valve, it is characterised in that: further include a special spanner, the special spanner is by handle and admittedly
Be scheduled on handle upper end two fixed columns composition, the fixed column it is identical as the installing port spacing of the swivel nut and with its gap
Cooperation.
The inflation safety valve advantage of the utility model is as follows: changing conventional radial inflation and fills to be axial, gasket is by gas valve core
Protection, and gas valve core is limited by silk braid again, spring pushes gas valve core to move to right locking high pressure gas in time after inflation.Simultaneously
With tool top gas spool to the left, high pressure gas that can be closed with removal.
The utility model is described further with reference to the accompanying drawings of the specification.
