Abstract
The utility model discloses an air exhaust plug for a domestic heating system, which is connected with a group of radiating fins through an air exhaust pipe. A casing is composed of a main casing, a sleeve, a joint, and a connecting pipe, the lower part of the inner part of the casing is provided with a hollow sealing floating cylinder, the upper part of the floating cylinder is connected with a needle valve, the upper part of the needle valve is positioned in a post cavity and is extended out of the air exhaust hole of the upper end of the post cavity, and the upper part of the needle valve is provided with a boss which is provided with a rubber washer. When water level is low, the air in a circulating water channel can be exhausted from the air exhaust hole slowly. When the water in a boiler is boiled, the water level rises, the floating cylinder pushes the needle valve upwards to a peak, the air exhaust hole is blocked by the needle valve, and the water can not spill out of the air exhaust pipe. The utility model has the advantages of high safety, practicality, and low cost.
Description
The utility model relates to a kind of family expenses soil heating installation exhaust plug, be a kind of valve gear that is specifically designed to family expenses soil heating installation,
Existing family expenses soil heating installation always is provided with a blast pipe in order well to realize hot water circuit, the gas of getting rid of in the water behind a certain group of radiator, this blast pipe is very long very high, is higher than the height of respectively organizing radiator far away.This is because native heating installation recirculated water is short out, can in above-mentioned blast pipe, overflow after the water in the stove is boiled, but this be so also in the boiler of being everlasting water overflow blast pipe after boiled, boiling water splashes within doors, and long high again blast pipe also hinders attractive in appearance.
The purpose of this utility model is at above-mentioned shortcoming, designs a kind of device, can effectively get rid of the gas in the water, and not make outside the boiling water discharger.
Scheme of the present utility model is: at the end of blast pipe one exhaust plug is installed, when the water of this exhaust plug in boiler did not have the boiling water position to hang down, the steam vent on it can effectively be got rid of the gas in the water, guaranteed that circulation waterway is unimpeded.When water was boiled in the boiler, the needle-valve in it was blocked steam vent, and boiling water can not be overflow outside the blast pipe.
The utility model is simple in structure, and is easily manufactured, easy to use.Can guarantee that circulation waterway is unimpeded, effectively get rid of gas, guarantee that boiling water does not overflow outside the blast pipe in the stove.Can not make the blast pipe excessive height yet, influence indoor attractive in appearance.
Below in conjunction with accompanying drawing the utility model is illustrated:
Fig. 1 is the utility model structure chart for the utility model uses figure, Fig. 2.
The back of fin (3) is connected to a blast pipe (2), and (1) is the location drawing of the present utility model, (4) water inlet pipe, (5) return pipe.As not using plug of the present utility model (1), then this blast pipe (2) is then far above present blast pipe.
Fig. 2 is the utility model structure chart.
Main casing (9) and sleeve (8) are formed shell, the upper end of main casing (9) has joint (13) and main casing (9) to be threaded, sleeve (8) and main casing (9) are threaded, the lower end of sleeve (8) is connected with adapter (6), adapter (6) is joined by an end of seal washer (7) and main casing (9), takes over terminal blast pipe (2) screw thread of (6) and fin (3) and joins.In the lower end of the housing of forming by main casing (9), sleeve (8), joint (13), adapter (6), sealing ring (7), the floating drum (10) of a sealing is arranged, hollow in floating drum (10) chamber can be floated when water level rises automatically.One post chamber (12) is arranged in the upper end of housing, there is a needle-valve upper end in post chamber (12), it is one closely-spaced that the lower end of needle-valve (11) and floating drum (10) have, needle-valve (11) upper end is positioned at post chamber (12) and stretches out outside the steam vent (14), one boss (17) is arranged at needle-valve (11) top, on a rubber washer (15) is arranged.The outer end portion of needle-valve (11) in post chamber (12) has a stop nut (15) and needle-valve (11) to be threaded.When the water level in the blast pipe was low, the gas in the circulation waterway was by discharging in the steam vent (16).When water was boiled, water level slowly rose, and floating drum (10) withstands needle-valve (11) slowly moves up needle-valve (11), and gas is pulled out outside the steam vent.When water level rose to peak, floating drum (10) pushed up needle-valve (11) to peak rubber washer (16) steam vent (14) is sealed up, and water can not spill outside the pipe when burning yet.The upper end of needle-valve (11) has one to lack the recessed exhaust of being convenient to.Stop nut (15) is used for preventing when reducing as far as possible that at needle-valve (11) needle-valve (11) from coming off.The distance of rubber washer (16) and stop nut (15) is greater than the length of post chamber (12).
Claims (1)
