flame arrester

Abstract

The invention discloses a fire barrier which comprises a shell, wherein sealed water is poured into the shell, an outlet pressure meter, an air inlet pipe, an air outlet pipe, an emptying pipe, a water inlet pipe and a water outlet pipe are arranged on the shell, and the air inlet pipe, the air outlet pipe, the emptying pipe, the water inlet pipe, the water outlet pipe and the outlet pressure meter are all provided with valves; the air inlet pipe stretches below the liquid level of the sealed water, the air outlet pipe is arranged above the liquid level of the sealed water, the shell is internally provided with fire retarding boards, the fire retarding boards are arranged between the air inlet pipe and the air outlet pipe, the front end and the rear end of each fire retarding board are connected with the front wall and rear wall of the shell, and the upper end and lower end of each fire retarding board are separated from the top and lower part of the shell. In the invention, the fire retarding boards are arranged between the air inlet pipe and the air outlet pipe, so that inlet air can be effectively prevented from splashing, so as to avoid that the outlet air carries with moisture; a sight glass is arranged between the two fire retarding boards, and the fluctuation of the liquid level of the sealed water between the two fire retarding boards is small, so that the observed liquid level best meets the actual height of the liquid level, and then the accuracy of pressure measurement of the shell is high.

Description

technical field [0001] The invention relates to a safety protection device for using flammable gas, in particular to a flame arrester. Background technique [0002] The flame arrester is a device used to prevent external flames from entering into equipment and pipelines containing flammable and explosive gases, or to prevent flames from spreading between equipment and pipelines. Existing flame arresters such as the Chinese utility model patent water-sealed flame arrester with the authorized publication number CN202048366U include a housing on which an air intake pipe and an air outlet pipe are arranged, an elevator is arranged at the bottom of the housing, and the top of the elevator is fixedly connected with a The liquid level stabilizing tank, the opening of the liquid level stabilizing tank faces upwards, the air intake pipe is inserted into the liquid level stabilizing tank, and a water circulation device is connected between the liquid level stabilizing tank and the inn...
