Abstract
The utility model relates to a leakage-proof safety device used on a gas stove or a gas water heater, belonging to a temperature controlling leakage-proof safety device. The utility model is composed of a spherical valve chamber, a valve ball, a counterweight ball, a transmission lever, a piston and a heat transferring pipe. The utility model is characterized in that the spherical valve chamber and the valve ball are arranged on a vent pipe at the front part of a gas switch; the heat transferring pipe is arranged near gas flames; the piston in the heat transferring pipe is connected with the counterweight ball and the valve ball through the transmission lever. When the gas flames are put out caused by extrinsic factors, the temperature is lowered, the piston slides downwards, the valve ball is driven to move upwards, and a vent hole is closed. The utility model has the advantages of simple structure, low cost, flexible closure and reliable usage.
Description
The utility model relates to a kind of leakproof safety device that is used for gas furnace or gas heater, belongs to temperature control leakproof safety device.
At present, normally used combustion gas (as natural gas, coal gas etc.), stove or gas heater, it opens or closes needs by human hand twist switch.Sometimes because of other reason (boiling is turned over excessive, wind, stops the supple of gas or steam and come gas etc. as boiling water, soup) causes gas furnace or gas heater fray-out of flame temporarily, often make the combustion gas spill and leakage, cause combustion gas poisoning or fire to take place, even cause casualties.Though now some combustion gas spill and leakage alarm devices, combustion gas spill and leakage safety device are arranged, need go to close by the people because of what have; The complex structure, the cost that have are higher, are actually used on gas furnace or the gas heater seldom.
The purpose of this utility model is to provide a kind of simple in structure, is used for gas furnace or gas heater, because of after gas flame extinguishes, can close the safety device of air supply pipe automatically.
In order to achieve the above object and requirement, the utility model by the following technical solutions: combustion gas leakproof safety device mainly is made up of passage 1, spherical valve chamber 2, valve ball 3, weighted spherical ball 4, transmission levers 5, piston 6 and heat-transfer pipe 7.Its characteristics are: spherical valve chamber and valve ball are installed on the breather pipe before the burnt gas switch, and heat-transfer pipe is installed near the gas flame, and the piston in the heat-transfer pipe is connected with weighted spherical ball and valve ball by transmission levers.Fill a kind of thermal expansion material in the heat-transfer pipe, as a kind of acolite that can replacement for mercury, this alloy by zinc, bismuth, tin, indium, gallium, form.When fray-out of flame, since the temperature reduction, the alloy liquid volume-diminished, and under the effect of weighted spherical ball, the driver's valve croquet moves up, and closes passage.The weight of weighted spherical ball needs the size according to the required power of lever system, regulates, and reaches the realization breather pipe and closes flexibly.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the front view of the utility model structure;
Fig. 2 is the part sectioned view of the utility model passage and spherical valve chamber.
During assembling, with reference to accompanying drawing 1, spherical valve chamber 2 is installed on the breather pipe, passage 1 communicates with breather pipe and source of the gas, and heat-transfer pipe 7 is installed near the gas flame.In use, when gas flame extinguished, Yin Wendu reduced the liquid alloy Volume Changes, and piston moves down, drive transmission levers 5 and move, weighted spherical ball 4 impels valve ball 3 to move upward in spherical valve chamber 2 to pressing down, block passage 1, thereby close passage, reach the purpose of leakproof.
