Description

Gas conversion valve for propane-butane combined use burner}

The present invention relates to a gas switching valve of a propane-butane gas combined burner, and more particularly, when propane gas is in use during propane gas, it can be ignited with butane gas and used continuously. No need to purchase, cost is reduced and you can purchase and use only the required amount without having to prepare a large amount of propane gas cylinders in advance. It is easy and convenient to use because it can be easily converted to butane gas when supply of propane is stopped. The present invention relates to a gas switching valve of a propane butane gas burner having no concern.

In general, butane gas, propane gas (LPG) and city gas (LNG) are widely used in homes and businesses.

Butane (butane) of the butane gas is one of the chain hydrocarbon, the formula is C4H10, the molecular weight is 58.1. There are two isomers, n-butane, in which four carbon atoms are continuously bonded in a chain, and isobutane, in which three carbon atoms are bonded to one carbon atom.

n-butane is also called normal butane, and often referred to as butane. It is contained in natural gas or petroleum cracking gas. Under normal temperature and pressure, it is a colorless gas, which burns well when air or oxygen is present, and the calorific value is 27,600 kcal / m3.

It is used as fuel for liquefied petroleum gas, and is also used for the production of butene and butadiene as petrochemical raw materials. It has a good liquefaction and is used as a main component of gas lighter fuel.

Isobutane is contained in natural gas or petroleum cracking gas like n-butane. Colorless gas, highly flammable and easily liquefied. Combination with propylene yields high octane gasoline. It is also used as a raw material for synthesizing isobutylene.

Butane gas having this characteristic is filled in a small sized aluminum container with proper pressure and sold at a supermarket or convenience store.The user can purchase a butane gas container on the market and install it in a small home burner that is easy to move. It is used to cook food or grill meat.

In contrast, propane in propane is a methane-based hydrocarbon, and the chemical formula is CH3CH2CH3, a colorless liquid with a mild irritant odor. The molecular weight is 44.1, the melting point is -187.69 ° C, the boiling point is -47.07 ° C, and the specific gravity is 1.547 (air is 1).

It burns with a spark that has a stronger brightness than ethane. Although the chemical reactivity is low, it is converted to propylene by the release of hydrogen, and formaldehyde or the like can be produced by air oxidation. It is contained in gas obtained from cracking (decomposition distillation) of natural gas and petroleum, and is industrially produced.

These gases are concentrated by oil absorption, activated carbon adsorption, liquefaction by compression and cooling, and the like, and separated by low temperature sorting or the like. The propane gas used as a household fuel is propane as a representative component, a mixture made of propylene butane and butylene, etc., and is referred to as liquefied petroleum gas or LPG. In addition, it is also used as a synthetic raw material of various substances, as a solvent and a refrigerant for refining lubricating oil.

Propane gas having such characteristics is filled and sold in a large-capacity gas cylinder compared to butane gas, which is sold in a small container with a small capacity, and is used in businesses such as homes and restaurants that are not equipped with city gas facilities.

However, because the large amount of propane gas used in a restaurant varies depending on the amount of gas stove or burner used in a restaurant or home, the amount of gas contained in the propane gas can't be known. The propane gas falls during the boiling of the soup, and at this time, there is a problem in that the home butane gas burner having only one at home has to be selected instead of soup, rice or stew to boil.

In particular, if you are cooking a customer's order at a restaurant that is open for lunch or dinner for office workers, or if a propane gas drops while the stew or meat is being grilled, replace it with a butane gas burner as a temporary measure. You can call and purchase, but the service is depreciated, which requires some time for the propane to be ordered and cannot be replaced during that time. There was a problem that was reduced and troubled.

In order to prevent this, the establishment must always secure two or three times the propane gas cylinders as necessary, so it is expensive to purchase and a large amount of maintenance costs are required. There was an issue added.

The present invention is to solve the conventional problems as described above, if the propane gas during use of propane gas can be continued to ignite again with butane gas, so you do not have to purchase a separate butane gas burner in the business or home separately It is possible to purchase and use only the required amount without having to prepare a large amount of propane gas cylinders in advance, and it can be easily converted to butane gas when the supply of propane gas is stopped. It is an object of the present invention to provide a gas switching valve of a propane butane gas burner.

In order to achieve the above object, the present invention is directed to a valve;

In the shape of a rod, a knob is coupled to the upper portion, and a screw fastening portion is formed at the lower portion thereof, and a butane gas closing recess formed at one side thereof is formed, and a butane gas supply hole is formed in which the circumferential edge is cut long from the butane gas closing recess. The other side of the butane gas closing recess is formed with a butane gas supply eccentric cam having a butane gas communication hole with a predetermined thickness cut inward from the circumferential edge, and one side of the opposite side of the butane gas closing recess is cut below the butane gas closing recess. The propane gas closing recess is formed, and a propane gas supply hole is formed in which the circumferential edge is elongated from the propane gas closing recess, and the propane gas communication hole is cut in a predetermined thickness from the circumferential edge to the other side of the propane gas closing recess. A valve shaft on which a propane gas supply eccentric cam is formed;

A valve actuating recess is formed into the center of the valve shaft with a rectangular facet, and a fastening portion is formed at the inner circumference of the upper end of the valve actuating recess, and a butane gas closing recess and a butane gas communicating hole of the valve shaft are formed. A fastening hole is formed, and a propane gas fastening hole communicating with the propane gas closing recess of the valve shaft and the propane gas communication hole is formed, and a burner fastening hole communicating with the butane gas supply hole and the propane gas supply hole is located between the propane gas fastening hole and the butane gas fastening hole.

By the butane gas supply eccentric cap 11, the operation pin 31 is slowly retracted inward, so that the flange 32 of the rear end enters the carbon resilient portion 335 and presses the carbon spring 34 to contract.

At this time, the butane gas injection hole 36 of the butane gas supply pipe 38 communicates with the butane gas closing recess 13, and the butane gas entering the butane gas closing recess 13 by an appropriate pressure is supplied with the butane gas below. The ball 14 enters the burner fastening hole 26 and is continuously supplied to the burner 52 through the burner pipe 50.

As described above, the present invention can be used by igniting butane gas again when propane gas is dropped during the use of propane gas, so it is not necessary to purchase a butane gas burner for outdoor use in a business or home, thereby reducing the cost and a large amount of propane gas containers in advance. It is possible to purchase and use only the necessary amount without having to provide it, and it can be easily converted to butane gas when the supply of propane gas is stopped, so it is simple and convenient to use, and there is no concern about fuel interruption.
