All about sanitary fittings

To install plumbing fixtures in the bathroom, various auxiliary parts are required, including fittings. This product is installed in pipelines and allows you to control the control in them. Today we'll talk about plumbing fixtures, their main features and varieties.

Plumbing fittings are special equipment designed to control the pipeline.

This design makes it easy to shut off the fluid flow in the pipe., regulate the pressure indicator and the pressure of the liquid, protect against an excessive increase in pressure inside, mix substances from different directions.

Depending on the type of construction, such products are divided into several types.

• Gate valves. These elements are of the shut-off type. In them, the main mechanism is located at an angle of 90 degrees to the centerline of the pipes. Such parts can be wedge and hose. They are made from a copper base.

• Gate. This part allows you to shut off the fluid supply using a special disc. It can be attached to the piping system using either a tightening or flanged connection. Sometimes welding is also used for fixing. The gates are distinguished by the greatest lightness, insignificant hydraulic resistance.

• Valve. This part is often referred to as a valve. They are created with a special poppet element, it can be either locking or regulating. Special diaphragm valves are very popular today, which allow you to shut off the flow of water using an elastic thin membrane.

• Tap. This product most often has a conical or cylindrical shape. It can rotate 90 degrees, some varieties can rotate 180 degrees. The valve can be either ball or shut-off.

• Fitting. Such elements act as connecting parts that allow pipes to be securely fastened together without changing their direction.

Plumbing fittings can be classified into several separate varieties, depending on the design features of the body.

• Pass-through system. This design consists of connecting pipes that are parallel to each other. In this case, direct-flow valves are distinguished, in which the spindle line is not perpendicular to the axis of the connecting pipes. Typically they are at a 45 degree angle. Axisymmetric valves are also distinguished, in which the movable section of the gate moves along the direction along the axis of the nozzles.

• Corner system. In this case, the axes of the inlet and outlet nozzles are placed perpendicularly or not parallel to each other.

• Multi-pass system. With such a system, the working part will enter simultaneously or alternately into one or several nozzles at once.

Depending on the purpose, these structures can be divided into several separate categories.

• Plumbing design, regulating. It is designed to independently establish the necessary temperature conditions, pressure level.Depending on the type of energy used, a category can be distinguished that functions from an external power supply device (most often from an electrical system), the second category will be powered by the energy of the working environment, for example, from a special pressure regulator.

• Plumbing system, locking and regulating. These products allow you to completely shut off the movement of flow through the pipeline. And also with the help of them it will be possible to simply increase or decrease the pressure inside.

• Distribution and mixing plumbing construction. These varieties allow you to set the required direction of water flow. And they also make it possible to mix various liquids with each other. Most often, various bellows regulators, mixing valves, and control valves act as such fittings.

• Safety plumbing fittings. Such systems are used to protect the pipeline from excessive pressure. They automatically release the media when needed. As a rule, valves of lever and spring types act as such devices.

Several groups should be distinguished in this classification.

• Manual control models. Such elements have the simplest design. They are also considered to be the most common patterns. Hand-made products work with the help of swing devices, valves.

• Remote control models. These parts do not have any adjustments on the body. They are equipped with special remote view adapters, thanks to which the devices are controlled from a certain distance.

• Drive type models. These varieties are installed directly on the plumbing equipment itself. In this case, the control is carried out using an electric drive.

• Automatic type models. Such products will consume energy directly from the working environment itself, and they can also receive the necessary signals from external sources.

Different models can be installed in different ways. Let's take a closer look at the most popular options.

• Coupling. With this method of installation, couplings with different threaded parts are used. This design is used quite often, including for fixing valves, various valves.

• Tsapkovy. In this case, the parts will be attached using a special external thread for a strong O-ring. The pin type of fixation is used for various, including more aggressive environments.

• Fitting. With this fixing, the fittings will be fixed to the fitting or to the nipple, which are located on the plumbing equipment itself. This technology is often used for ball valves.

• Welding fixation. This option is considered the most reliable and durable, but difficult. The fittings have special pipes, which make it possible to weld them to plumbing fixtures.

• Flanged. Fastening of products is carried out using flanges. Such fasteners are quite strong and reliable, they provide durable connections.

• Coupling. The products are connected to the system by tying the studs between the flanges. This method is the most durable and reliable.
