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. Common appliances that use regulators include gas stoves, propane grills, or oxy-fuel bottles for welding. Each type of regulator's components consists of a set spring attached to a rod that runs down from a set screw through a diaphragm into the valve. There are three primary operating components working together to regulate the pressure within the valve. The loading mechanism determines the delivery pressure. Most often, it is a spring.589. In the United States, tetrahydrothiophene (thiophane) or amyl mercaptan are also approved odorants, although neither is currently being utilized. An LPG regulator is a device that maintains a stable downstream 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.

A hose is a flexible hollow tube designed to carry fluids from one location to another. Hoses are also sometimes called pipes (the word pipe usually refers to a rigid tube, whereas a hose is usually a flexible one), or more generally tubing. The shape of a hose is usually cylindrical (having a circular cross section). Hose design is based on a combination of application and performance. Common factors are size, pressure rating, weight, length, straight hose or coilhose, and chemical compatibility. Applications mostly use nylon, polyurethane, polyethylene, PVC, or synthetic or natural rubbers, based on the environment and pressure rating needed. In recent years, hoses can also be manufactured from special grades of polyethylene (LDPE and especially LLDPE). Other hose materials include PTFE (Teflon), stainless steel, and other metals. Dredge rubber hoses have a long story, 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.
