Abstract
The utility model belongs to a mechanical valve, which is suitable for liquid circulating pipeline systems, in particular to exhausting accumulated air in water heat supply pipeline systems. The valve is opened and closed with balanced stress, flexibility and reliability via the combined interaction of floater weight, water buoyancy and the elastic force of an elastic member. A forced gas-liquid separator is utilized, gas and liquid can be fast separated, the liquid is avoided spraying out with the gas, and the working reliability and the practicability of the valve are enhanced. The utility model has obvious effect on increasing the heating efficiency of heat circulation pipelines.
Description
The utility model belongs to a kind of mechanical valve, is applicable in the liquid network circulating line, particularly is applicable in the water heat supply ductwork and gets rid of air accumulation.
The utility model is by Chinese patent 88203980.6,89207274.1,89221676.X patent development, the deficiency of these several patents is that valve opening and closing only depends on the float of water to drive the float effect, active force is unbalanced, seal not tight, the easy adhesion of float and valve body, start underaction, gas-liquid separation is slow.
The purpose of this utility model provides a kind of valve stress equalization, opens and closes flexibly, and sealing is tight, the outlet valve that gas-liquid separation is fast.
The purpose of this utility model is achieved through the following technical solutions.Automatic control pressure vent includes valve body and is fixed on exhaust nozzle, float and the valve lever of settling in float guide pillar, valve gap and the valve hole thereof of its bottom.Valve lever is inserted in the exhaust nozzle through hole, is positioned with elastic member by nut, and elastic member can adopt spring, cooperation to form.Self-sealing joint 19 lower ends can also can directly be incorporated pipe network system into by steam-water separator.
Its working principle is such, float can be along to drifting along by guide pillar and valve lever location, and when accumulating air entrapment in the pipeline, float relies on deadweight by valve lever and elastic member, being suspended in apart from valve cock has on the position of suitable distance, float not can with the adhesion of valve body bottom.Along with the variation of hydraulic pressure and water capacity, squeeze air and discharge by exhaust nozzle.Exhaust finishes, and float is at buoyancy and be enclosed within the rebounding force double action of the elastic member on the valve lever and promote, and by last potting pad the exhaust nozzle exhaust hole is closely closed.In the exhaust process, the liquid that is mixed with gas is when flowing through steam-water separator, since the unexpected variation of volume, hypotension, and speed up gas and liquid is separated, and avoids liquid to spray with gas.
Compared to existing technology, the utlity model has following advantage: valve seal power makes the valve sealing closely by buoyancy deadweight, water buoyancy, elastic member elastic force triple interaction, opens flexibly, reduces the gas-liquid mixed flow and discharges, and has improved the functional reliability of valve.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the sectional view of automatic control pressure vent.
Accompanying drawing 2 is the steam-water separator structural drawing.
