Description
The technical field is as follows: the utility model relates to a can effective control gas overflow automatic accuse stream device of closing, the utility model discloses a technique can be applied to in the gas valves such as the bottled liquefied petroleum pressure regulator of various models, pipeline gas pressure regulator, pipeline gas self-closing valve, prevents to take over the overlength because of the gas outlet, or air inlet pressure is too big, causes the overflow value too big, and the gas leaks and can't close, arouses the emergence of fire explosion accident to improve and use gas safety.
Background art: with the development of society and the wide application of new energy, gas becomes a necessary fuel energy in industry and life, and enters thousands of households. During the use of gas by residents, various accidents such as leakage, poisoning, fire or explosion occur almost every day, wherein the accidents caused by the gas leakage are all the same during the use of the gas. The utility model discloses an application in the liquefied petroleum pressure regulator of various models, pipeline gas pressure regulator and pipeline gas self-closing valve etc. gas valves can prevent effectively that the gas from leaking, reduces the loss, protects life safety, improves quality of life.
The invention content is as follows: the utility model relates to a can effective control gas overflow the automatic accuse stream device of closing.
In order to achieve the above invention contents, the technical scheme of the utility model is as follows:
the utility model provides a can effective control gas overflow automatic accuse that closes and flow device comprises rubber closure plate 1, arc rubber muscle 2, tubular rubber seat, its characterized in that: the rubber closing sheet 1 is connected with the tubular rubber seat through the arc-shaped rubber rib 2 and is matched with the tubular rubber seat.
The technical scheme of the utility model still include:
the automatic gas flow control device is characterized in that the tubular rubber seat is made of special gas rubber into a cylindrical shape and consists of a closing opening 3 and a base 4.
The automatic gas flow control device is characterized in that the arc-shaped rubber rib 2 is made of special gas rubber, one end of the arc-shaped rubber rib is connected with the tubular rubber seat, the other end of the arc-shaped rubber rib is connected with the rubber closing piece 1, and the size and the thickness of the arc-shaped rubber rib 2 are set according to sensitivity requirements.
The automatic gas flow control device is characterized in that the rubber closing piece 1 is made of special gas rubber into a square sheet shape, one side of the square sheet shape is longer than the diameter of the closing opening 3, and the other side of the square sheet shape is shorter than the diameter of the closing opening 3 and can be tightly matched with the closing opening 3.
The utility model has the advantages that: the automatic gas flow control device is arranged at the gas inlet of various types of gas valves such as bottled liquefied petroleum pressure regulators, pipeline gas pressure regulators and pipeline gas self-closing valves, and can effectively prevent the occurrence of fire and explosion accidents caused by the fact that the overflow value is increased and the gas leakage cannot be closed due to overlong gas outlet connecting pipes of the gas valves such as the pressure regulators and the self-closing valves or the overlarge pressure of the gas inlet. The utility model discloses simple structure, technical performance is stable, need not to adjust, and the installation is easy, and is safe, reliable, durable.
Description of the drawings: the attached drawing is a structural schematic diagram of the automatic gas flow control device.
In the figure, 1 is a rubber closing sheet, 2 is an arc-shaped rubber rib, 3 is a closing opening, and 4 is a base.
The specific implementation mode is as follows: referring to the attached drawings, the automatic gas flow control device of the utility model comprises a rubber closing piece 1, an arc-shaped rubber rib 2 and a tubular rubber seat, wherein the tubular rubber seat is made of special gas rubber into a cylindrical tubular shape and consists of a closing port 3 and a base 4; the gas-fired pipe-shaped rubber closing piece comprises an arc-shaped rubber rib 2, wherein the arc-shaped rubber rib is made of special gas rubber, one end of the arc-shaped rubber rib is connected with a tubular rubber seat, the other end of the arc-shaped rubber rib is connected with a rubber closing piece 1, and the size and the thickness of the arc-shaped rubber rib 2 are set according to sensitivity requirements; the gas-fired square sheet type gas-fired rubber sealing device comprises a rubber sealing sheet 1, wherein the rubber sealing sheet is made of special gas rubber, one side of the square sheet is longer than the diameter of a sealing opening 3, and the other side of the square sheet is shorter than the diameter of the sealing opening 3 and can be tightly matched with the sealing opening 3.
The automatic gas flow control device of the utility model is in a normally open state before use, and only when gas leaks or the pressure is too high, the rubber closing sheet 1 and the closing port 3 can be automatically closed, thereby realizing the flow control function; when the air vent valve is used for removing faults and ventilating normally, the rubber closing sheet 1 and the closing opening 3 are automatically separated and are restored to a normally open state under the action of the arc-shaped rubber ribs 2.
