CN2164486Y - Gas. liquid fuel universal combustion gate valve - Google Patents

Abstract

The utility model relates to a gas and liquid fuel universal combustion gate valve comprising a gas gate valve part and a liquid gate valve part. The inner structures of two gate valves are same with the common gas gate valve, and a liquid straw which is directly downward led to the bottom of a steel bottle is arranged in the liquid gate valve. The gas and liquid gate valves are directly led to the gas and liquid outlet of the valve body by an annular groove, and thus two gate valves can be respectively or simultaneously opened or closed, and has simple operation, safety and convenience. The utility model is matched with gas and liquid fuel universal ignition ranges, can make full use of the raffinate at the bottom of the liquefied gas steel bottle, saves energy, and can be suitable for a plurality of liquid fuels.

Description

Gas. liquid fuel universal combustion gate valve

The utility model valve kind, the general burning gate valve that is adopted on a kind of specifically gas, the liquid fuel steel cylinder.

At present the gate valve that uses on the cylinder for liquefied gas can only make the LNG gasifaction that can gasify naturally in the bottle pass through, at the bottom of the liquefied gas residue that can not gasify naturally in causing bottle residues in bottle.By each steel cylinder can 15kg calculating now, when summer was more than 30 ℃, the raffinate remaining quantity was 1-2kg, and winter is below 10 ℃, more than 2-3kg.For raffinate can further be burnt again, the liquid gas user who has adopts and shakes bottle, and the method at the bottom of the heating bottle makes LNG gasifaction, and this not only can not fundamentally solve the problem that raffinate is used up, and easily causes the personal safety accident.Steel cylinder is long more service time, and raffinate wherein can increase, and the raffinate of removing wherein also is troubling problem.

The purpose of this utility model is the problem that exists with gate valve at existing, is intended to design a kind of gaseous fuel in the cylinder for liquefied gas to be passed through, and the liquid fuel general burning gate valve of gas, liquid fuel that also can pass through.Both made and also can use whole this gate valve of bottle liquid fuel.

The purpose of this utility model realizes in the following manner, gas, the liquid general burning gate valve that burns, and the gas gate valve is made up of valve body 2, gas inlet pipe 3, valve 4, connecting rod 5, valve rod 6, seal washer 8, clamping cap 9, gas handwheel 7.Except that the gas gate valve is arranged, also has the liquid gate valve on the valve body 2.Liquid gate valve internal structure is with the gas gate valve, but the liquid suction pipe 1 of logical steel cylinder bottom is housed for 15 times at the liquid through-hole of its valve 4.The outlet of liquid gate valve communicates with valve body gas, liquid outlet 16 by circular groove 17.Outside the outlet of gas gate valve air outlet 10, straight-through valve body circular groove 17 gentle, liquid outlets 16 are arranged.

Accompanying drawing is the utility model structural representation

With reference to accompanying drawing, the utility model is designed to side valve with the raw-gas gate valve on the agent structure basis that does not change steel cylinder and former liquid gas gate valve, overhead-valve then is the liquid gate valve, the internal structure of liquid gate valve is identical with the gas gate valve, and the liquid suction pipe 1 of a through steel cylinder bottom is only arranged.Suction pipe 1 can make it abundant application with the raffinate sucking-off in the cylinder for liquefied gas, both for the user saves fund, provides effective means for the thorny problem that solves raffinate again.

Gas gate valve, liquid gate valve respectively have air flue, and fluid passage outlet, two outlets are all passed through circular groove 17 when valve body comes out, and communicate at gas liquid outlet 16.So this general gate valve gas, fluid passage both can be distinguished opening and closing, opening and closing simultaneously again.11 valve packing rings, 12 " O " RunddichtringO, 13 nuts, 14 locking cards among the figure.

During can fuel, the gate valve on the former liquid gas steel cylinder is dismantled, changes the utility model, no matter be to open gas handwheel 7, or liquid handwheel 18, all can be in steel cylinder gas-filling, liquid or gas, liquid combination.

" gas, the general pulse igniting kitchen range of liquid " (applying for a patent simultaneously) supporting use of the utility model and my design, both applicable to gaseous fuels such as liquefied petroleum gas (LPG), also applicable to liquid fuels such as liquefied gas residue, petroleum ethers, its concrete use principle and method are as follows:

During as the raffinate at the bottom of the need burning cylinder for liquefied gas, open side valve earlier, gas is through the utility model in the steel cylinder, and suction tude, valve, the gasifying pipe of igniting kitchen range spray air inlet liquid mixing chamber from the threeway shower nozzle and enter the burning of kitchen range face.After treating flameholding, open overhead-valve again, close side valve, then liquid fuel is through the utility model, and the suction tude of igniting kitchen range enters the gasifying pipe heating and gasifying again by valve, sprays air inlet liquid mixing chamber from the threeway shower nozzle and enters the burning of kitchen range face.Atmospheric temperature generally needs 10-15 days in time below 0 ℃, then only needs 10 days at normal temperatures, then the raffinate (proportion 0.682kg/l) of steel cylinder bottom can be burnt down prior to the liquefied petroleum gas (LPG) (proportion 0.582kg/l) that can gasify naturally.Then, only need open side valve using gases fuel, till burning down.

As being liquid fuel in the steel cylinder, then need the air of can certain pressure in bottle.Open overhead-valve during use earlier and close for 1 second, making has certain amount of fluid fuel in the gas pipeline, open side valve then, makes a bottle interior air enter pneumatic tube, mixes entering the kitchen range mixing chamber simultaneously with liquid in pipe, with vaporific mixed combustion.After treating the gasifying pipe heating, open overhead-valve again, turn off side valve, kitchen range get final product proper functioning.

The utility model need not change the steel cylinder structure, no matter be gas in the steel cylinder, or liquid fuel all can be general.Use this general gate valve the raffinate in the cylinder for liquefied gas can be drawn burning, saved the energy, efficiently solve the handling problem of raffinate again.The utility model is simple to operate, safe and reliable, a valve is dual-purpose.
