Degassing filter

Abstract

A degassing filter comprises a barrel and an inlet formed on one side of the barrel, wherein the barrel is internally provided with a filter cylinder; the top of the filter cylinder is fixedly connected and communicated with an exhaust device; the inlet is formed in a tangential direction of a side wall of the barrel; an opening matched with the exhaust device is formed at the top of the barrel; the exhaust device comprises an inner cylinder; the top of the inner cylinder penetrates through the opening and extends to the outside of the barrel; a sealing device is arranged at the top of the inner cylinder; an exhaust port and an vent valve mounted at the exhaust port are formed and arranged on the sealing device; the inner cylinder is further internally provided with a floating ball matched with the exhaust valve; guide ports are uniformly distributed in a side wall of the inner cylinder; a horizontal plane where the guide ports are located is lower than a horizontal plane where the floating ball is located; an outlet is formed at the bottom of the barrel; an outlet pipe is arranged at the outlet; one end of the outlet pipe is communicated with the bottom of the filter cylinder; and the other end of the outlet pipe penetrates through the outlet and extends to the outside of the barrel. According to the filter, gas is separated from oil by a centrifugal force; the gas can be helped to timely escape from the oil; a thorough exhaust effect is achieved; and similarly, the filter is applicable to a situation of higher oil flow velocity.

Description

technical field [0001] The invention relates to a filter device for pipeline fluid, in particular to an air-eliminating filter. Background technique [0002] The degassing filter is one of the auxiliary equipment of the flowmeter, which can separate the solid impurities and gases in the pipeline fluid, prevent the solid impurities and gases in the fluid from affecting the measurement accuracy of the flowmeter, and prolong the service life of the flowmeter. [0003] After the fluid enters the degassing filter, it passes through the internal filter to remove solid impurities. When the liquid passes through the filter assembly, it will change the flow direction, so that the free gas and part of the dissolved gas in the oil can fully escape and gather in the On the top of the getter filter, a gas space is formed, and an oil-gas interface appears. As the gas increases and the pressure increases, the oil-gas interface descends, and the floating ball descends with the oil-gas inte...
