Gas eliminator with position moving prevention function

Abstract

The invention provides a gas eliminator with a position moving prevention function. The gas eliminator comprises a hook, a flexible conduit, a spray prevention cover and a hanging ring, wherein the hook is arranged at the left side of the upper end surface of an upper end cover; the lower end of the flexible conduit is fixed at the right side of the upper end surface of an end cover; the upper endof the flexible conduit is fixed on the left side of the lower end surface of the spray prevention cover; the spray prevention cover is arranged above an automatic exhaust valve; the hanging ring isfixed at the right side of the lower end surface of the spray prevention cover. By using the design, the problems that the original gas eliminator is lack of the spray prevention cover position limiting function, the spray prevention cover can easily move through the exhaust pressure, and the dustproof reliability is insufficient can be solved. The gas eliminator has the advantages that the position moving prevention function is realized; the regulation is convenient; safety and reliability are realized.

Description

technical field [0001] The invention is an air eliminator with the function of preventing channeling and belongs to the technical field of petrochemicals. Background technique [0002] The air eliminator is an accessory device of the liquid flowmeter, which is mainly used for the measurement of crude oil and petroleum products, the purification of solid foreign matter before transportation, and the elimination of gas to ensure the normal operation of the flowmeter and the accuracy of measurement. Its working principle is through the valve When the core moves downward, the air eliminator automatically exhausts, and the exhaust pressure is 1.6 to 4MPa. With the discharge of gas, the liquid level gradually rises and lifts the floating ball, pushing the valve core up to close the automatic exhaust valve. When the fluid flows in from the inlet end of the filter degasser, it passes through the filter screen installed in the housing, and the solid foreign matter carried by the flui...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the automatic exhaust valve is covered by a blowout preventer, thereby reducing the amount of dust entering the exhaust pipe and reducing the probability that the mixture of exhaust gas and oil sprayed by the automatic exhaust valve will be mixed with dust to block the automatic exhaust valve. However, the existing air eliminator still has shortcomings. It has no limit function of the blowout cover, and the exhaust pressure is easy to cause the blowout cover to move, and the dustproof reliability is insufficient.
