A pipe fitting is a part that connects a pipe into a line. According to the connection method can be divided into socket pipe fitting, threaded pipe fittings, flange pipe fittings and welded pipe four categories. Made of the same material as the pipe. There are elbow (elbow), flange, three-way pipe, four-way pipe (crosshead) and reducing pipe (size head) and so on. A place where a pipe bends; an elbow. Flange is used to connect pipe to pipe parts, connected to the end of the pipe, tee is used for the place where three pipes meet; A place where four pipes meet; a quad pipe. A place where two pipes of different diameters are connected.
(1) cut-off valve: cut-off valve also known as closed-circuit valve, its role is to connect or cut off the medium in the pipeline. Block valves include gate valves, globe valves, plug valves, ball valves, erfly valves and diaphragm, etc.
(2) check valve: Check valve calls boiler check valve again check valve or check valve, its action is to prevent medium backflow in pipeline. Pump water off the end of the boiler check valve also belongs to the category
(3) mud relief valve: the role of relief valve is to prevent pipeline or device medium pressure in excess of the specified value, so as to achieve the purpose of safety protection.
(4) control valve: Control valve including control valve, throttle valve and pressure reducing valve, its role is to regulate the pressure of the media, such as flow parameters.
(5) shunt valve: shunt valve, including a variety of distribution valves and traps, etc., its role is to distribute, separate or mixed media pipeline.
What are the advantages?
Different pipe fittings are slightly different.
Sheung Shui: If lined with plastic steel pipe, pipe diameter DN100 following wire connection, elbow, tee, four, hoop, on the wire, diameter change, wire plug and so on.
Pipe diameter DN100 or more trench connection, trench elbow, trench three, trench four, trench flange, mechanical three, mechanical four, and so on.
If the words of plastic pipe (PPR water pipe, etc.): hot melt tee, hot melt elbow, direct hot melt, hot-melt variable diameter, directly within the wire, the wire directly, wire elbow, 90, etc.
Water: mechanism of cast iron pipe, then: 45 degrees oblique tee, along the water tee, 45 degrees inclined four-way, with the water Sitong, double 45 degree elbow, 90 degrees elbow, 45-degree bend, are three, four, the riser check port, the level of cleaning pipe, blocking, and so on.
Plastic pipes, such as UPVC drains, Bonding: 45 degrees oblique tee, water three, 45 degrees inclined four, water four, 45 degree elbow, is three, four, riser inspection mouth, horizontal cleaning pipe, plugging and so on.
