Description

An improved natural gas relief valve

Technical Field

The utility model relates to the technical field of relief pipes, and more specifically to an improved relief valve for natural gas.

Background Art

The vent pipe is a device specially used to discharge the air or gas inside the pipeline. When the pipeline is put into operation, the vent pipe is used to discharge the air in the pipe. When the pipeline or equipment is under maintenance, the vent pipe can be used to discharge the gas in the pipe to prevent the formation of explosive mixed gas in the pipeline. Its function is to provide overpressure protection for downstream equipment and higher pressure.

At present, the vent pipes used in economic construction are generally made of steel. Although this type of vent pipe has good strength, it is generally installed outdoors underground, which leads to a relatively humid environment. Although steel vent pipes are generally made of stainless steel, long-term exposure to this environment will cause corrosion and damage to the steel vent pipe, affecting its use and safety, and easily causing dangerous accidents, making it inefficient for users to handle accidents.

Utility Model Content

According to one aspect of the utility model, a natural gas improved relief valve is provided, which is installed on the air inlet pipes on both sides of the valve body. The natural gas improved relief valve comprises a PE relief pipe, a relief valve, a flange root and an electric fusion sleeve. The relief valve is installed on the top of the PE relief pipe, and the bottom of the PE relief pipe is connected to the flange root through the electric fusion sleeve. The flange root is connected to the ball valve through a flange plate.

Preferably, based on the above scheme, it further comprises a steel protection tube, wherein the protection tube is sleeved outside the PE discharge pipe.

Preferably, based on the above scheme, the protective cylinder includes a cylinder body, a connecting ear plate and a connecting frame, the connecting ear plate is installed at the bottom of the cylinder body and is evenly arranged along the circumferential direction of the cylinder body, and the connecting ear plate is connected to the flange plate by bolts; the connecting frame includes a connecting plate, a connecting rod and a clamp connected to the PE discharge pipe, the connecting rod is installed on the top outer edge surface of the cylinder body through the connecting plate, and the clamp is welded to the end of the connecting rod.

Preferably, based on the above solution, the end of the connecting rod is provided with a thread, the connecting plate is provided with a screw hole, and the connecting rod and the connecting plate are locked and adjusted by a nut.

The utility model discloses an improved natural gas relief valve, which adopts a PE relief pipe to replace a traditional steel relief pipe, and can be quickly and conveniently installed on a ball valve in combination with a flange root and an electric fusion sleeve, and the replacement is convenient and quick. A detachable protective cylinder is arranged outside the PE relief pipe, so as to protect the PE relief pipe and avoid damage thereof caused by external force, thereby affecting its safety. At the same time, the protective cylinder and the PE relief pipe are detachably connected, so that maintenance is convenient and cost-effective.
