Abstract
The utility model relates to an automatic exhaust valve utilizing the theory that water and air have different specific gravity, a radiator has pressure which can be changed. The automatic exhaust valve is mainly composed of a floating ball pressure valve and a piston pressure limiting valve. The valve can be arranged on any radiator or all sets of radiators in a water heating system instead of a manual exhaust valve, automatic exhaust can be realized under the condition of large pressure variation in the radiator, and in other under conditions, the automatic exhaust valve is used for semi-automatic exhaust. The automatic exhaust valve having convenient operation is favorable for heating people, simultaneously the automatic exhaust valve can effectively prevent users from draining hot water, energy can be saved, and scale in the water heating system is reduced.
Description
The present invention relates to a kind of automatic exhaust device of hot water radiation.
The manual bleed valve that uses on hot water radiation at present need often turn venting, metals run out if forget to close then to cause; If at indoor unmanned or night, just had no idea, thereby influenced heating.It is also provided convenience for groups of people put hot water, and moisturizing just increases energy consumption and incrustation scale.
At the problems referred to above, the outlet valve that the invention provides a kind of automatic, semi-automatic exhaust and can not discharge water, it is not only easy to use and help energy-conservation and the reduction incrustation scale, for people's heating brings convenience.
The present invention utilizes pressure and the vicissitudinous principle of pressure in water, gas proportion difference and the radiator, be made of float-ball type pressure valve and piston type pressure-limit valve.Minimum exhaust pressure: 0.03MPa.
Special plug (11) as shown in the figure: at G1 1/2 " is gone up and is bored a bottom outlet, adds bolt (7) and forms the cavity that is connected; The bottom constitutes the float-ball type pressure valve by plastics ball float (10) and rubber gasket (9); Top constitutes the piston type pressure-limit valve by bolt (7) and rubber cup (5), piston (4), spring (3), bolt (2); When making plastics ball float (10) throw off with rubber gasket (9), bar (8), (1) uses; (6) be sealing gasket; Bolt (2) is tightened, and effect of the present invention is equivalent to a plug.
The present invention can be installed to that any one group and all groups need on the radiator of exhaust in the water heating system, the promptly manually position of bleed valve, mounting point, vertically upward.Under the bigger situation of variation in pressure, can realize automatic vent, all the other are semi-automatic exhaust, promptly click bar (1) with hand, make plastics ball float (10) and rubber gasket (9) but just exhaust of disengagement.
Accompanying drawing is a sectional drawing of the present invention.
Working principle: when the kettleman opens pumps water, pressure in the radiator rises, if there is gas this moment, then gas jack-up rubber cup (5), bar (8), piston (4), spring (3), bar (1), when pressure reaches certain value, pressure-limit valve is opened fully, and gas is by lateral opening the discharge by speed limit of bolt (7).Exhaust finishes, water enters in the float valve, plastics ball float (10) floats the wiper seal that contacts and utilize water prior to water and rubber gasket (9), if the interior full water of radiator this moment, water is then owing to pressure rising jack-up rubber cup (5), bar (8), piston (4), spring (3), bar (1), do not wait pressure-limit valve to be opened fully, plastics ball float (10) has sealed with rubber gasket (9) and has finished.
Water pump one stops, and when the pressure in the radiator dropped to certain value, bar (8) utilized the power of spring (3) to force plastics ball float (10) and rubber gasket (9) to be thrown off, so that exhaust next time.
Claims (1)
1, a kind of automatic, semi-automatic outlet valve that is used on the hot water radiation, it be by bar (1), bolt (2), spring (3), piston (4), rubber cup (5), rubber gasket (6), bolt (7), bar (8), rubber gasket (9), plastics ball float (10), special plug (11) totally 11 parts constitute, it is characterized in that: the bottom is by plastics ball float (10) and rubber gasket (9) formation float-ball type pressure valve; Top constitutes the piston type pressure-limit valve by bolt (7) and rubber cup (5), piston (4), spring (3), bolt (2).
