Abstract
The invention discloses a current limiting device which is special for a fuel gas valve and capable of effectively controlling fuel gas overcurrent closing. The current limiting device is characterized in that the device is composed of a rubber closing base, a rubber balance rib and a rubber closing cover, wherein the rubber closing base is made to be a round rube shape with rubber special for fuel gas and is composed of a closing port and a fixing seat; the rubber balance rib is a round hook-like flat rib made of the rubber special for the fuel gas, one end of the rubber balance rib is connected with the rubber closing base, and the other end of the rubber balance rib is connected with the rubber closing cover; and the rubber closing cover is made to be a round flake shape with the rubber special for the fuel gas, the diameter of a round flake is larger than that of the closing port, and the round flake and the closing port can be matched tightly. The current limiting device is simple in structure, stable in technical performance, free of adjustment, easy to install, safe, reliable and durable.
Description
Technical field：The present invention relates to the special current limliting dress of gas valve that a kind of energy effective control combustion gas excessively stream is closed
Put, patented technology of the present invention can be applicable to the bottled liquefied petroleum pressure regulator of various models, pipe gas pressure regulation
In the gas valves such as device, pipe gas self-closing valve, prevent from taking over long because of gas outlet, or inlet pressure be excessive,
Cause overcurrent value excessive, gas leakage cannot be closed, cause the generation of fire explosion, so as to improve use
Gas safety.
Background technology：With the development of society, the extensive application of new forms of energy, combustion gas have become industry with life
Upper necessary fuel energy, into huge numbers of families.In resident is using gas process, almost have everyday
Various leakages, be poisoned, catch fire or explosion accident generation, wherein in combustion gas use, because of combustion gas
Leakage, the accident of initiation can be found everywhere.Liquefied petroleum pressure regulator, pipeline of the patent of the present invention in various models
Application in the gas valve such as gas pressure regulator, governor and pipe gas self-closing valve, can be effectively prevented gas leakage, subtract
It is few to lose, life security is protected, is improved the quality of living.
The content of the invention：The present invention is the special current-limiting apparatus of gas valve that a kind of energy effective control combustion gas excessively stream is closed.
The technical scheme is that to reach foregoing invention content：
The special current-limiting apparatus of gas valve that a kind of energy effective control combustion gas excessively stream is closed, by elastomeric closure seat, rubber
Glue balance muscle (2), elastomeric closure lid (1) are constituted, it is characterised in that：Elastomeric closure seat, elastomeric closure lid (1)
It is connected with each other with rubber balance muscle (2), and cooperates.
Technical scheme also includes：
The special current-limiting apparatus of described gas valve, it is characterised in that elastomeric closure seat is made up of combustion gas special (purpose) rubber
Circular tube shaped, and be made up of closing mouth (3) and fixed seat (4).
The special current-limiting apparatus of described gas valve, it is characterised in that rubber balance muscle (2) is by combustion gas special (purpose) rubber system
Justify hook-shaped into flat muscle, and one end connection elastomeric closure seat, other end connection elastomeric closure lid (1).
The special current-limiting apparatus of described gas valve, it is characterised in that elastomeric closure lid (1) is by combustion gas special (purpose) rubber system
Circular lamellar, and circular piece is with diameter greater than closing mouth (3) diameter, and can be fitted close.
Advantages of the present invention：The special current-limiting apparatus of gas valve are installed on the bottled liquefied petroleum pressure regulation of various models
At the gas valve air inlets such as device, pipeline gas governor, pipe gas self-closing valve, effectively can prevent because of pressure regulation
The adapter of the combustion gas such as device, self-closing valve valve air gate is long, or inlet pressure is excessive, causes overcurrent value to become big,
Gas leakage cannot be closed, and cause the generation of fire explosion.Present configuration is simple, and technical performance is steady
It is fixed, without the need for adjusting, install easy, safety is reliable, durable.
Description of the drawings：Accompanying drawing is the special current-limiting apparatus structural representation of gas valve.
Specific embodiment：Referring to the drawings, the special current-limiting apparatus of gas valve of the present invention are by elastomeric closure seat, rubber
Glue balance muscle (2), elastomeric closure lid (1) are constituted.Pipe is made by combustion gas special (purpose) rubber including elastomeric closure seat
Shape, and be made up of closing mouth (3) and fixed seat (4)；It is made up of combustion gas special (purpose) rubber including rubber balance muscle (2)
Flat muscle circle is hook-shaped, and one end connection elastomeric closure seat, other end connection elastomeric closure lid (1)；Including rubber
Close lid (1) and round sheet, and circular piece made with diameter greater than closing mouth (3) diameter by combustion gas special (purpose) rubber,
And can be fitted close.
The special current-limiting apparatus of gas valve of the present invention only work as gas leakage using normally open is front in, or
During pressure super large, elastomeric closure lid (1) can be closed automatically with mouth (3) is closed, and realize closing function；In row
Except failure, when normal ventilation is used, under rubber balance muscle (2) effect, elastomeric closure lid (1) with close mouth (3)
It is automatically separated, returns to normally open.
