Abstract
The utility model relates to an automatic air exhauster used for the tail end or a peak of a hot water heating system and a central air conditioner, which improves an isolating automatic air exhaust valve and has the advantages of simple structure, reliable operation, no failure, and long service life. The utility model is composed of a valve body and a floating ball which is provided with an inner nozzle, and is provided with a self-closing valve. In addition, the utility model is convenient for disassembly and assembly when a system runs.
Description
This use is novel to be the automatic exhaust device of hot-water heating system and central air-conditioner end or peak.
The floating type automatic control pressure vent that tradition is used exists and stops up exhaust port because of impurity in the water or fouling and cause exhaust malfunctioning, produces defect such as run, drip, leak, and automatic vent is unreliable.
February 1 nineteen ninety-five Chinese patent announcement 93241494.X patent---isolated automatic control pressure vent---complex structure, cost of production height, be not easy to promote the use of.
Design the novel purpose of this use and be a kind of improvement to isolated automatic control pressure vent, should strengthen the reliability of automatic exhaust device, simplified structure reduces cost again, is convenient to promote the use of.
In chew the formula valve air relief and have only two bare bones to form, they are ball floats of chewing in valve body and the band.Below in conjunction with accompanying drawing its structure and working principle are described further.
Among the figure: chew in 1 valve upper cover, 2 valve bodies, 3 ball floats, 4,5 cushion rubbers; There is pilot hole 6 at the valve upper cover center, the pilot hole inner wall smooth, there is horn mouth the lower end, in chew and navigate within the pilot hole, in chewed vent hole 7 vent holes below tight cover one cushion rubber.Valve pocket 9, spring 10, spool 11 and cushion rubber 12 have been formed a self closing stop valve, and be convenient in system's loading and unloading in service.
Working principle is, during operation, entering part liquid in the valve body, ball float come-up, in chew along moving on the pilot hole, vent hole 7 is sealed, and ball float rising simultaneously is obstructed, because the pressure effect in the system, water level in the valve body continues to rise, the ball float draft amount increases, and buoyancy increases, and vent hole 7 sealings are tighter, simultaneously, air in the valve body is compressed, and when the pressure balance in the valve body, forms the separating surface 8 of liquid and gas in the valve body naturally, vent hole 7 is in the top of liquid level 8 forever, vent hole 7, pilot hole 6 does not reach liquid, can not polluted, and has guaranteed the reliability of venting.When air quantity in the valve body increased, liquid level 8 descended, and the ball float draft amount reduces, and buoyancy reduces, and ball float sinks by deadweight, and vent hole 7 is decontroled, and gas is emitted automatically, works repeatedly to reach the automatic deflation purpose.
Claims (3)
1, a kind of be used for hot-water heating system and central air-conditioner end or peak in chew the formula valve air relief, it is made up of the ball float chewed in valve body and the band, it is characterized in that: there is pilot hole at the loam cake center of valve body, in chewed vent hole, in chew and navigate within the pilot hole.
2, chewing the formula valve air relief according to claim 1 in described is characterized in that: there is horn mouth the higher and below of the loam cake centre pilot hole inner face degree of finish of valve body.
3, chewing the formula valve air relief according to claim 1 in described is characterized in that: in the below of the vent hole chewed O-ring seal is arranged, cushion rubber with in chew combine tightr.
