Abstract

The utility model discloses an air eliminator, which comprises a container, an outlet is arranged on one side of the upper part of the container, and a ball valve is arranged in the outlet. When air which is contained in liquid which enters the container penetrates a liquid film to overflow to the top of the container, the liquid level in the container can descend with increase of the air; when the liquid level descends to a certain height, the float valve is opened under the action of gravity of a floating ball to cause the air to be discharged to eliminate the air in the liquid which is measured to improve the measuring accuracy of a flowmeter. The utility model can be suitable for various measuring instruments.

Description

Air separator

The utility model relates to a kind of device of cooling down.Specifically, be a kind of air separator that is used for being isolated and excluded the contained gas of liquid.

As everyone knows, the metering at industrial liquid realizes by flowmeter.All contain all gases in most of fluids to be measured in varying degrees,, just can influence the measuring accuracy of flowmeter if allow these gases enter flowmeter.At present,, can't eliminate the gas that enters in the liquid and enter flowmeter, make that the precision of flowmeter is not high owing in liquid gaging system, there is not the device of cooling down.

The purpose of this utility model is to provide a kind of air separator.This air separator can be eliminated the gas in the fluid to be measured, improves the measuring accuracy of flowmeter.

Air separator of the present utility model comprises container, and its design feature is that this container top one side has outlet, and valve seat is arranged in the outlet, and there is flange this valve seat outer end, and this flange joins with the flange of outlet outer end.Be welded with baffle ring in the middle of the valve base cavity, there is valve body the baffle ring inboard, and annular boss is arranged in the middle of valve body one side, and the cylindrical of annular boss is straight through the straight warp of interior circle less than baffle ring, matches to make things convenient for the two.The annular boss excircle to the valve body lateral surface on pad is arranged, this pad is fixed on the valve body by means of screw and trim ring.There are gland and pad in the opposite side center of valve body.Also be with valve pocket on the valve body.The inner end of valve seat is fixed with lid, and the inner segment of valve seat circumferentially has through hole.One end of valve rod passes the center that lid, valve pocket and gland are fixed on valve body successively from the inner end, its other end has key seat, and an end of the upper end of web member and club is hinged on this key seat by means of pin respectively.One end of the lower end of web member and key seat is hinged, and the other end of key seat is fixed on and covers.The other end of club has ball float, and this ball float is in the top of container intracavity.

The utility model is under application state and the supporting use of flowmeter.When overflowing in container top when contained gas breakthrough liquid film in the liquid that enters container, the liquid level in the container can descend along with the increase of gas.When liquid level dropped to a certain height, ball float was discharged gas under the action of gravity of ball float and open.Thereby eliminated the gas in the fluid to be measured, improved the measuring accuracy of flowmeter.

Below in conjunction with accompanying drawing the utility model is described in further details:

Fig. 1 is an air separator cross-sectional schematic of the present utility model, and Fig. 2 is the A enlarged drawing of Fig. 1.

As depicted in figs. 1 and 2, air separator of the present utility model comprises container 1, is welded with an outlet on top one sidewall of container, and a flange 8a is welded in the outlet outer end, this flange is enclosed within on the valve seat 10 by means of screw and circumferential circular hole and the flange 8b flange 8b that is fixed together, and welds together.Valve seat 10 is a pipe, and its external diameter is less than the internal diameter of outlet, and makes and keep enough gaps after the two assembling.Valve is done in the middle of 10 inner chambers baffle ring 9 to be installed, the external circumferential of this baffle ring and the interior circle of valve seat 10 weld installed inside one valve body 19 of baffle ring 9 mutually, be processed with annular boss in the middle of the lateral surface of valve body, the external diameter of annular boss is less than the internal diameter of baffle ring 9, so that the two is assembled together.The annular boss outside is equipped with pad 21, and this pad is fixed on the valve body 19 by means of screw and trim ring 18.The medial surface center of valve body 19 is equipped with gland 17, and this gland seals, is fixed together with valve body 19 by securing member and pad 22.Be with valve pocket 16 on the valve body 19, the opening end shield of this valve pocket is buckled on the valve body 19.A lid 11 is fixed in the inner end of valve seat 10, and all there is through hole at the center of lid 11 and valve pocket 16, gland 17, the center that an end of valve rod 7 passes successively and covers 11, valve seat 16 and gland 17 are fixed on valve body 19.The center of lid 11 and valve pocket 16 has copper sheathing 14 and 15 respectively, on the valve rod 7 of valve pocket 16 inboards axle sleeve 23 is installed also.The other end of valve rod 7 welds a key seat 5, and an end of the upper end of web member 4 and club 3 is hinged on this key seat with pin 6 respectively.The downside of lid 11 welds a key seat 12, and the lower end of web member 4 is hinged by pin 13 and this key seat.The other end of club 3 is installed a ball float 2, and this ball float is in the top of container 1 inner chamber.

The inner segment of valve seat 10 circumferentially is processed with a plurality of through holes.Down, after fluid to be measured entered container 1, gas wherein can be broken through liquid film and overflow in the top of container 1 in working order, and the liquid level in the container 1 can descend along with the increase of the gas of assembling.When liquid level dropped to a certain height, valve body 19 moved in can be under the effect of ball float gravity, makes valve open, and the gas that accumulates in container 1 top can pass the circumferential through hole of valve seat 10 inner segments and baffle ring 9 along the gap between valve seat 10 and outlet successively and discharge.Thereby realize eliminating the purpose of gas in the liquid.
