Bottle valve with filter device

Abstract

The invention discloses a bottle valve with a filter device. The bottle valve comprises a connecting pipe, a sealing top cover, a conversion constant-pressure chamber, a pressure relief controller, apressure measurer, a filter bottle valve constant-pressure chamber, a fixed pipe, a movable clamping ring, an air valve nozzle, a stop fixed ring, a pressure adjuster, a pressure adjusting screw rod and a fixed bolt; the sealing top cover is mounted rightly above the filter bottle valve constant-pressure chamber; the sealing top cover and the filter bottle valve constant-pressure chamber are positioned in the same axis; the pressure relief controller is movably mounted in the middle of the pressure relief controller, and is in clearance fit; the filter bottle valve constant-pressure chamber communicates with the fixed pipe; and the stop fixed ring is arranged at the lower end of the fixed pipe. In the bottle valve with the filter device, a second gas filter bin and a first gas filter bin are structurally arranged in the filter bottle valve constant-pressure chamber; the first gas filter bin realizes primary filtration on gas; and the second gas filter bin can timely realize secondary filtration, so that impurities and particles in the gas can be totally filtered.

Description

technical field [0001] The invention relates to a bottle valve with a filtering device, which belongs to the field of high-pressure gas cylinders. Background technique [0002] Cylinder valves are an essential part of high-pressure gas cylinders. There are many types of valves for existing gas cylinders, generally with functions such as inflation, decompression, and pressure display; there is no bottle valve that can filter water and oil, so that oil and water vapor will enter the gas cylinder when inflated, and long-term accumulation will cause damage to the gas cylinder. The service life of the gas cylinder and the safety of use are harmful. [0003] The prior art discloses a bottle valve with an application number of CN201220148703.5, which includes a bottle valve body and a filter device. The filter device includes: a filter body, one end of which is sealed and connected to the bottle valve body; a filter assembly, It is located in the filter body; the connection joint...
