Abstract

The utility model relates to a double force floating ball steam trap, belonging to the universal machine. The upper part of the trap body of the utility model is provided with the outlet of a double discharging hole, and a floating ball in the trap body is matched with a trap seat to form the seal; the upper part of the trap body is provided with an auxiliary trap body, and an auxiliary trap cover and an auxiliary trap body are connected to form a chamber which is provided with a trap plate. The utility model has the advantages that the air in the chamber can be discharged rapidly, the floating ball can be opened rapidly and exactly, the upper and the lower discharging holes of the trap body can be simultaneously opened, and condensed water can be discharged rapidly and thoroughly.

Description

Double-force type free floating ball drain valve

The utility model is a kind of double-force type free floating ball drain valve, belongs to universal machine.

At present, the drain valve that drain valve manufacturer produces must deaeration (as adopting manual free style drain valve) in its chamber of drain valve that every dependence buoyancy elements starts, otherwise buoyancy elements is malfunctioning, can not normally drain condensed water.And rely on drain valve upper metal film to experience the variation of the temperature difference, produce deformation of unevenness to reach the drain valve of deaeration, the shortcoming of this structure is: if pipeline medium overpressure, or temperature does not reach the required temperature difference of metallic thin film variation, then air can not be got rid of, and ball float will be malfunctioning, the valve bad sealing, cause steam leakage and can not reach the effect of choke draining, perhaps reduce the utilization efficiency of drain valve.

The purpose of this utility model provides a kind ofly can discharge the body cavity air quickly and effectively, makes ball float open and close rapidly and accurately the double-force type drain valve that water displacement is big.

The utility model is realized with following technological scheme: be provided with the import of band filter screen 1 in the left side of valve body 10, the below is provided with pollutant exhaust hole 8, and plug 7 is mated.The valve seat of fixing with plug 12 11 is housed below the right side of valve body 10, and top is provided with 6,13 double outlets of portalling, and the ball floats 9 in the valve body 10 cooperate the formation sealing with valve seat 11.On the top of valve body 10 auxiliary valve body 2 is housed, secondary valve gap 4 connects with auxiliary valve body 2 in the chamber that forms valve block 3 is housed, and it is firm by Bolt Connection to be added with pad between valve body 10 and the valve gap 5.

It is rapid to the utlity model has the endoceliac air of eliminating, and ball float is opened and closed rapidly accurately, and the upper and lower drain boles of valve body can be opened simultaneously, and it is thorough rapidly to drain condensed water, and Applicable scope is extensive, and volume is little, the big outstanding feature of eliminating condensed water ability.

Now the utility model is described in further detail in conjunction with the accompanying drawings.

Fig. 1 is that the utility model master looks sectional view.

Fig. 1 is the utility model specific embodiment.Be provided with the import of band filter screen 1 in the left side of valve body 10, the below is provided with pollutant exhaust hole 8, and plug 7 is mated.The valve seat of fixing with plug 12 11 is housed below the right side of valve body 10, and top is provided with the outlet of 6,13 two tap holes, and the ball floats 9 in the valve body 10 cooperate the formation sealing with valve seat 11.On the top of valve body 10 auxiliary valve body 2 is housed, secondary valve gap 4 connects with auxiliary valve body 2 in the chamber that forms valve block 3 is housed, and it is firm by Bolt Connection to be added with pad between valve body 10 and the valve gap 5.

The utility model is compared with drain valve in the market, has following advantage: this pair Power formula drain valve is to be provided with two taps in the valve body chamber, can draining can get rid of sky again Gas. When this valve is installed on the pipeline, when connecting vapour source, be full of medium in the valve, ball float Be subjected to the pressure that medium produces and be adjacent to valve seat and export, this moment the condensation flow goal the bottom. With This while, valve body internal upper part element valve block is opened air and section under the effect of inlet pressure Divide condensed water to flow out by upper tap. The port of export in the valve block lower end of high speed steam flow warp Pressure reduces, and under the pressure-acting that rebulids in the control room, valve block is closed, no Draining. Along with the steam condensing in control room, pressure drop, under the effect of inlet pressure, Valve block is unlocked again, and drain valve is draining again, and the condensed water with valve body lower end constantly increases simultaneously Many, liquid level rises, and moves away valve seat on the ball float, and the lower end passage of valve is opened valve body lower end Condensed water also be discharged from, until the condensed water liquid level drops to the precalculated position, this moment ball float return The position, closed valve seat outlet draining stops, and goes round and begins again, and is interrupted in the periodicity discharge line Condensed water. When if condensed water is many in the equipment pipeline, not only the ball float opening water discharge is simultaneously secondary Valve block in the valve is the while opening water discharge also, so discharge capacity is greater than like product. The utility model Double-force floating-ball steam trap can not only make steam and moisture from, can also be at the normal temperature state Under make air and moisture from, the condensed water in the air compressor machine storage tank can be discharged such as it, at present each The Free Float Type Steam Trap test(ing) medium that state produces all uses steam, relies on the two gold of temperature difference control The deformation of unevenness that belongs to sheet is got rid of endoceliac air, and the control ball float opens and closes. And this practicality is new Type also can be tested without vapor medium, utilizes secondary valve valve block dump valve body cavity sky Air, the control ball float opens and closes, and reaches the effect that choke is discharged. It can be assisted in the remover apparatus The condensed water of (in container, pipeline) sudden fast rush prevents because condensed water row is unclean The water of forfeiting vapour production between causing and causing shakes serious phenomenon.
