Gas regulator's Full-time Job

Designed in 1835, the gas regulator's concept is easy, and its impact has been long-lasting. There are various types of regulators, but their function is the same: to use a valve system to control natural gas or propane pressure or other gas flow.pressure regardless of changes in gas flow and upstream pressure. Among them, the LPG jumbo regulator and the LPG quick-on regulator are typical representatives.

which features high strength and flexibility. A flexible dredging hose widely used in dredgers to convey silt or gravel. It is resistant to abrasion and wear to ensure long service life. Types of flexible dredge hose include the floating rubber hose, discharge hose, suction hose, armored hose and ceramic hose. To achieve a better pressure resistance, hoses can be reinforced with fibers or a steel cord. Commonly used reinforcement methods are braiding, spiraling, knitting and wrapping of fabric plies. The reinforcement increases the pressure resistance but also the stiffness. To obtain flexibility, corrugations or bellows are used. Usually these corrugated internal or helical reinforcement rings are applied to maintain these corrugated or bellowed structures under pressure.

The gas hose includes a pipe joint, the pipe joint is composed of a pipe body and a steel sleeve fastened to one end of the pipe body, the pipe body has a through hole, and the one end of the pipe body is formed with a an annular coupling groove into which the hose is inserted, the axial depth of the annular coupling groove is greater than the length of the steel sleeve, and a part of the inner surface of the annular coupling groove is a tapered surface, a step is formed where the inner end of the tapered surface abuts another part of the inner surface of the annular coupling groove. The structure avoids the phenomenon that when the pipe joint is matched with the hose, the hose is inserted too deeply into the pipe joint, which causes deformation of the end of the pipe joint, which is beneficial to the smooth flow of gas and has high safety. A circular arc transition is adopted at the junction between the outer surface and the inner surface of the annular coupling groove to prevent stress concentration.

A gas stove is a stove that is fuelled by combustible gas such as syngas, natural gas, propane, butane, liquefied petroleum gas or other flammable gas. Before the advent of gas, cooking stoves relied on solid fuels such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was established in England in 1836. This new cooking technology had the advantage of being easily adjustable and could be turned off when not in use. The gas stove, however, did not become a commercial success until the 1880s, by which time supplies of piped gas were available in cities and large towns in Britain. The stoves became widespread on the European Continent and in the United States in the early 20th century. Gas stoves became more common when the oven was integrated into the base and the size was reduced to better fit in with the rest of the kitchen furniture. By the 1910s, producers started to enamel their gas stoves for easier cleaning. Ignition of the gas was originally by match and this was followed by the more convenient pilot light. This had the disadvantage of continually consuming gas. The oven still needed to be lit by match and accidentally turning on the gas without igniting it could lead to an explosion. To prevent these types of accidents, oven manufacturers developed and installed a safety valve called a flame failure device for gas hobs (cooktops) and ovens. Most modern gas stoves have electronic ignition, automatic timers for the oven and extractor hoods to remove fumes. Gas stoves are a significant source of indoor air pollution, and require good ventilation to maintain acceptable air quality.
