According to building codes, when installing pipelines transporting hot, cold water, steam and other media, it is required to install three-way valve for manometer.
It provides the ability to check and disable the meter. The valve allows you to relieve pressure, blow out the outlet, which prevents the needle from sticking, increases the accuracy of its readings. Lack of fittings can lead to accidents and serious damage to pipelines.
Execution options
The raw material for the manufacture of three-way valve bodies is brass, which can withstand significant loads. It is resistant to wear, aggressive substances, high temperatures, and is not prone to corrosion.
There are the following types of three-way valves:
- Cork tension. It has a simple design and is presented in four modifications. Among the disadvantages of such fittings are the likelihood of the plug shank breaking off due to insufficient metal hardness, the need for significant efforts.
- Ball with drainage. The crane has a compact size, is not prone to accumulation of debris in flow areas, is characterized by a high degree of tightness and ease of use. Can be used in stagnant areas. The control is carried out using a handle in the form of a lever.
- Button. Avoids constant pressure of the medium on the working mechanism of the measuring device. Measurements are carried out by pressing a button.
To connect three-way valves for manometers to pipelines, external and internal threads are used. This method of fastening ensures the reliability of fixing the reinforcement, dismantling when replacing without destroying the communications section.
Advantages
Three-way valves for manometers retain their functionality for a very long time. They are also characterized by:
- low coefficient of hydraulic resistance;
- reliability, structural strength;
- ease of installation, maintenance, which do not require the use of special equipment.
Three-way valves can be in several positions. In the first case, when the manometer is connected to the communications, the pressure of the transported medium is measured. If the device does not have access to the pipeline and is connected to an external air environment, the indicators always correspond to zero. Another position is required when connecting the test measuring device to the main pressure gauge.
