Fireproof ring for forged steel oiling valve

Abstract

The invention discloses a fireproof ring for a forged steel oiling valve in the technical field of forged steel oiling valves. The fireproof ring comprises a valve body. A fireproof ring body is arranged on the top of the valve body and comprises a fastening ferrule and a fixing ferrule. Screw rods are arranged on the outer wall of the upper side and the outer wall of the lower side of the right end of the fastening ferrule correspondingly. Limiting holes matched with the screw rods are formed in the outer wall of the upper side and the outer wall of the lower side of the left end of the fixing ferrule correspondingly. A sealing gasket is arranged on the connecting portion of the fastening ferrule and the fixing ferrule. Fireproof layers are arranged on the inner wall of the fastening ferrule and the inner wall of the fixing ferrule correspondingly. Steel pipes are arranged on the bottoms of the fireproof layers. Fireproof airbags are connected to the bottoms of the steel pipes. Through pipes are uniformly arranged on the bottoms of the fireproof airbags, thus the connecting portion of a protecting ring will not be corroded, and the service life of the fireproof ring is prolonged.Meanwhile, by means of a limiting rod, connection of the fireproof ring is more compact, fast flame retarding can be achieved in the valve body, the overall flame retarding property of the valve bodyis enhanced, and the use performance of the forged steel oiling valve is improved.

Description

technical field [0001] The invention relates to the technical field of forged steel oil injection valves, in particular to a fire ring for forged steel oil injection valves. Background technique [0002] Forged steel oil injection valves are generally equipped with a fire protection ring. The fire protection ring is a shell made of metal materials, and the interior is filled with a flame-retardant expansion core material to achieve the effect of flame retardancy. The existing fire protection rings on forged steel oil injection valves are generally only It can flame-retardant the outside of the fuel injection valve. If the inside of the valve body of the forged steel oil injection valve cannot be flame-retardant, the oil injection valve will be damaged faster. At the same time, the existing fire protection ring is generally connected by external screws, and the screws are easily exposed to the outside for a long time. Corrosion causes the loosening of the fire ring, thereby r...

The existing fire protection rings on forged steel oil injection valves are generally only It can flame-retardant the outside of the fuel injection valve. If the inside of the valve body of the forged steel oil injection valve cannot be flame-retardant, the oil injection valve will be damaged faster. At the same time, the existing fire protection ring is generally connected by external screws, and the screws are easily exposed to the outside for a long time. Corrosion causes the loosening of the fire ring, thereby reducing the flame retardant effect of the fire ring
