Abstract
The utility model provides a gas water-blocking device, comprising a housing with an air inlet and an air outlet. The housing is provided with a cavity which is communicated with the air outlet. The end of the venting blanking plug is communicated with the air inlet, and the other end, which is provided with vent holes communicated with the cavity on the circumference, extends into the cavity. The cavity is provided with a floating ball. The utility model is connected in the gas pipe, and the user makes the water pipe stagger joint to the gas pipe when the gas equipment is installed and maintained. When the water enters the pas pipe, the water is stopped from entering the gas pipe network and the equipment, so the utility model is very safe.
Description
Technical field:
The utility model belongs to family expenses, commercial gas pipeline safety means, and especially to enter the combustion gas water blocking device of gas pipeline and facility relevant with anti-sealing.
Background technology:
At present, when family expenses, commercialization etc. are installed and keep in repair gas appliance such as water heater, because of carelessness water inlet pipe is linked to each other with fuel gas inlet.Because water pressure is much larger than gaseous-pressure, water will enter gas pipeline in a large number rapidly, make in whole building even the whole sub-district gas pipeline and be injected into water, cause the accident of stopping the supple of gas or steam, and damage gas-fired equipment, and, can waste great human and material resources like this and put in order next inconvenience to resident living owing to the difficult eliminating of water electrode in the gas pipeline.
The utility model content:
The purpose of this utility model is exactly in order to overcome above deficiency, providing a kind of is connected with gas pipeline, can make the user when installing and keep in repair gas-fired equipment, stop water to enter combustion gas water blocking device gas ductwork and equipment, safety when causing water to enter gas pipeline water inlet pipe misconnection Gas Pipe.
The purpose of this utility model is achieved like this:
The utility model combustion gas water blocking device comprises the housing that contains air inlet and gas outlet, the cavity that communicates with the gas outlet is arranged in the housing, ventilation plug one end communicates with air inlet and the other end stretches into the passage that communicates with cavity is arranged on its periphery in the cavity, and ball float is housed in the cavity.
The sphere that cooperates with the ball float top surface is arranged at above-mentioned cavity top, and sealing effectiveness is better.
There is pipe joint above-mentioned housing top, and there is pipe joint ventilation plug below, can adopt six square tube joints or cubic pipe joint.
The fuel gas ball valve that has two ends to be communicated with cavity and gas outlet respectively in the above-mentioned housing has switch knob on the fuel gas ball valve, become the combustion gas ball valve that blocks water.
When the utility model inserts in the gas pipeline, when when installing and keep in repair gas-fired equipment, during with air inlet pipe misconnection Gas Pipe, water enters in the cavity by ventilation plug in the utility model and the passage on it, because the proportion of ball float is less than the proportion of water, ball float under the effect of water will rise with cavity on sphere be adjacent to, water is sealed in the cavity and can not continues to rise and enter in the gas pipeline of back.
The utility model is connected in the gas pipeline, makes the user when installing and keep in repair gas-fired equipment, with water pipe misconnection gas pipeline, when causing water to enter gas pipeline, stops water to enter gas ductwork and equipment, safety.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 enters among Fig. 1 the ball valve location drawing behind the cavity for water.
Fig. 3 is another structural representation of the utility model.
Fig. 4 is for entering among Fig. 3 the ball valve location drawing behind the cavity when water.
The specific embodiment:
Embodiment 1:
Fig. 1 has provided present embodiment 1 structural representation.The top that contains the housing 3 of lower end air inlet 1 and gas outlet, upper end 2 is one six square thread pipe joint 4.The cavity 5 that communicates with the gas outlet is arranged in the housing.Ventilation plug 7 one ends that there are six square thread pipe joints 6 lower end are communicated with air inlet and the other end stretches in the cavity and a plurality of passages that communicate with cavity 8 are arranged on its periphery.Ball float 9 is contained in the cavity.The sphere 10 that cooperates with ball float is arranged at the cavity top.
Referring to Fig. 2, when water when air inlet enters cavity by ventilation plug and passage, ball float rises, and is adjacent to cavity top sphere the gas outlet is blocked, and seals, and stops water to enter gas pipeline or gas-fired equipment.
Embodiment 2:
Fig. 2 has provided present embodiment 2 figure.Present embodiment 2 is basic same with embodiment 1.Not existing together is the fuel gas ball valve 11 that has two ends to be communicated with gas outlet and cavity respectively in housing, the switch knob 12 that is connected with fuel gas ball valve.Formed the combustion gas ball valve that blocks water.
Fig. 4 is for entering the combustion gas shown in Figure 3 ball float lifting position figure behind the cavity of ball valve that blocks water when water.
